Make an update request using Axios in React and Material UI - reactjs

I am pretty new to React, and the only CRUD functionality I have done has been in MVC.net, so I am pretty lost here and none of the tutorials I am finding seem to be the situation I have going on...or maybe I am just misunderstanding them. The tips I got with my initial question helped, but I am still no getting it to work, so hopefully now I have supplies enough info to help other help me. I did no include all of the input fields because their are like 15 and it was just redundant.
I am pulling up the modal using this onClick event:
onClick={()=> {handleEditModal(item)}}
modalFunctions.js
// Modal Functionality
export function ModalFunctions() {
const [selectedRecord, setSelectedRecord] = useState([]);
const [openModal, setOpenModal] = useState(false);
const handleEditModal = item =>{
setOpenModal(true)
setSelectedRecord(item)
}
return {
selectedRecord,
setSelectedRecord,
openModal,
setOpenModal,
handleEditModal,
handleDetailModal
}
}
// Form Functionality
export function FormFunctions(validateOnChange = false, validate) {
const [values, setValues] = useState('');
const [errors, setErrors] = useState({});
const handleInputChange = e => {
const { name, value } = e.target
setValues({
...values,
[name]: value
})
if (validateOnChange)
validate({ [name]: value })
}
return {errors, handleInputChange, setErrors, setValues, values}
}
DataTable.js
// Imported Modal Functions
const {
selectedRecord,
openModal,
setOpenModal,
handleEditModal,
handleDetailModal
} = ModalFunctions();
const baseURL = 'http://localhost:8080/api/tanks';
// Fetch Data
useEffect(() => {
const fetchData = async () =>{
setLoading(true);
try {
const {data: response} = await axios.get(baseURL);
setTableData(response);
} catch (error) {
console.error(error.message);
}
setLoading(false);
};
fetchData();
}, [baseURL, setTableData, setLoading]);
// The Modal
return(
<Modal
title={ "Editing: " + (selectedRecord.tankName) }
openModal={openModal}
setOpenModal={setOpenModal}
>
<TankEdit
selectedRecord={selectedRecord}
setOpenModal={setOpenModal}
openModal={openModal}
/>
</Modal>
)
TankEdit.js
export function TankEdit(props) {
const { baseURL, openModal, selectedRecord, setOpenModal, setTableData } = props;
const validate = (fieldValues = item) => {
let temp = { ...errors }
if ('tankName' in fieldValues)
temp.tankName = fieldValues.tankName ? "" : "This field is required."
setErrors({
...temp
})
if (fieldValues === values)
return Object.values(temp).every(x => x === " ")
}
const {
values,
setValues,
errors,
setErrors,
handleInputChange,
} = FormFunctions(true, validate);
useEffect(() => {
if (selectedRecord !== null)
setValues({
...selectedRecord
})
}, [selectedRecord, setValues])
function editRecord() {
axios.put(`${baseURL}`, {
title: "Success",
body: "The record had been successfully updated"
}).then ((response) => {setTableData(response.data);})
}
const handleSubmit = e => {
e.preventDefault()
if (validate()) {
editRecord(values);
}
setOpenModal(false)
}
const item = values; // used for easier referencing (matches table item)
return (
<Form onSubmit={handleSubmit} open={openModal}>

<Controls.Button

My company is only wanting a Read and an Update function, since Creating and Deletion will be handled another ways, so this is my final hangup. I think I am close, but I am missing something.
Can anyone point me in the right direction?
THANKS!!!!

If you want to write an update request you would use axios.put to send the data to your back-end.
In your handleSubmit function you do:
let response = await axios.put('http://-------/api/tanks', { name: 'tank' });
(The second parameter is an object that needs to contain all the form data fields)
Also make sure you call e.preventDefault() in the handleSubmit function so you don't accidentally navigate elsewhere.
Then you will update your database or whatever using your back-end.

for update you should use put or patch method
and you should send id of item you want to update in request url.
I insert 2 example here.
this is for put:
const res = await axios.put('/api/article/123', {
title: 'Making PUT Requests with Axios',
status: 'published'
});
this is for patch:
const res = await axios.patch('/api/article/123', {
title: 'Making PUT Requests with Axios',
status: 'published'
});

useState in parent component not keep state, when parent component's callback function is called from child component

Update
This maybe a Formik bug, and I have switched to https://react-hook-form.com, as Formik has not been updated for a while.
https://github.com/jaredpalmer/formik/issues/3716
Context
I'm using React, Formik, and google-map-react to allow store owner edit their store address with google map place autocomplete.
I have three components:
EditStoreInfoPage is the page component, which contains EditStoreInfoForm.
EditStoreInfoForm is the form component, which contains FormikAddressField. I uses Formik here.
FormikAddressField is the one form field that supports google place autocomplete.
Store information will be fetched from backend in EditStoreInfoPage, and passed down to EditStoreInfoForm and FormikAddressField. Whenever a new address is typed in FormikAddressField, it calls a callback function handleStoreLocationUpdate passed down from EditStoreInfoPage.
Issue
Render the page without any issue. I see that formValues are populated corrected with the data fetched from backend.
However, once I finished typing the address, the form get cleared except the store address is still there.
From the console output of above screenshot, I can see that function handleStoreLocationUpdate get called, however, console.log(formValues); in function handleStoreLocationUpdate of EditStoreInfoPage contains empty value for store fields. I was expecting that the formValues here still kept the value fetched from backend, not sure why these values get wiped out as I use React useState.
Any idea what went wrong?
Code
EditStoreInfoPage
This is the React component that first call backend API to get the store information based on storeIdentifier. formValues will be populated with these information, as you can see that setFormValues is being called. formValues is passed down to child component EditStoreInfoForm as props.
type EditStoreInfoPageProps = {
storeIdentifier: string;
};
const EditStoreInfoPage = (props: EditStoreInfoPageProps) => {
let navigate = useNavigate();
const [formValues, setFormValues] = React.useState<StoreAttributes>({
storeName: "",
storeLocation: "",
storeLocationLongitude: 0,
storeLocationLatitude: 0,
});
// Get store info.
React.useEffect(() => {
const user: CognitoUser | null = getCurrentBusinessAccountUser();
if (!user) {
Toast("Store Not Found!", "Failed to get store information!", "danger");
} else {
const storeIdentifier: string = user?.getUsername();
getStoreInfo(storeIdentifier)
.then((response) => {
setFormValues({
storeName: response?.storeName || "",
storeLocation: response?.storeLocation || "",
storeLocationLatitude: response?.storeLocationLatitude!,
storeLocationLongitude: response?.storeLocationLongitude!,
});
})
.catch((error) =>
Toast(
"Store Not Found!",
"Failed to get store information!",
"danger"
)
);
}
}, []);
const handleStoreLocationUpdate = (newStoreLocation: string) => {
const geocoder = new window.google.maps.Geocoder();
console.log("handleStoreLocationUpdate");
console.log(newStoreLocation);
console.log(formValues);
const geocodeRequest = { address: newStoreLocation };
const geocodeCallback = (
results: google.maps.GeocoderResult[] | null,
status: google.maps.GeocoderStatus
) => {
if (status === "OK") {
if (results && results[0]) {
const formValuesClone: StoreAttributes = structuredClone(formValues);
formValuesClone.storeLocation = newStoreLocation;
formValuesClone.storeLocationLatitude =
results[0].geometry.location.lat();
formValuesClone.storeLocationLongitude =
results[0].geometry.location.lng();
setFormValues(formValuesClone);
} else {
Toast("Not valid address!", "Please input a valid address", "danger");
}
} else {
Toast("Not valid address!", "Please input a valid address", "danger");
}
};
geocoder.geocode(geocodeRequest, geocodeCallback);
};
const handleSubmit = (data: StoreAttributes) => {
updateStore(props.storeIdentifier, JSON.stringify(data, null, 2))
.then((response) => {
if (response.status == 200) {
Toast(
"Updated!",
"The store information has been updated. Redirect to store page...",
"success"
);
navigate("/stores/" + props.storeIdentifier);
} else {
Toast(
"Updated failed!",
"Failed to update store information.",
"danger"
);
}
})
.catch((error) => {
Toast("Updated failed!!", error.message, "danger");
});
};
const handleUpdate = (data: StoreAttributes) => {
// make a deep clone here, as formValues here is an object.
console.log("handleUpdate");
const copy = structuredClone(data);
setFormValues(copy);
};
return (
<EditStoreInfoForm
formValues={formValues}
handleStoreLocationUpdate={handleStoreLocationUpdate}
handleUpdate={handleUpdate}
handleSubmit={handleSubmit}
/>
);
};
export default EditStoreInfoPage;
EditStoreInfoForm
EditStoreInfoForm is the form component. I use Formik here. It renders the form with props.formValues. It contains a child component FormikAddressField which will be used to support google place auto complete.
export type EditStoreInfoFormProps = {
formValues: StoreAttributes;
handleStoreLocationUpdate: any;
handleUpdate: any;
handleSubmit: any;
};
const EditStoreInfoForm = (props: EditStoreInfoFormProps) => {
console.log("EditStoreInfoForm");
const onBlur = () => {
console.log(props.formValues);
}
return (
<div className="flex justify-center items-center">
<Formik.Formik
initialValues={props.formValues}
enableReinitialize={true}
validationSchema={validationSchema}
validateOnChange={false}
validateOnBlur={false}
onSubmit={(values) => {
props.handleSubmit(values);
}}
>
{({ }) => (
<Formik.Form className="w-1/3">
<div className="form-group">
<div>
<FormikTextField
label="Store Name"
name="storeName"
placeholder={props.formValues?.storeName}

</div>
<div className="form-group">

<StoresGoogleMapLocation

</div>
</Formik.Form>
)}
</Formik.Formik>
</div>
);
};
export default EditStoreInfoForm;
FormikAddressField
FormikAddressField is the field for autocomplete. See https://developers.google.com/maps/documentation/javascript/place-autocomplete to know what it is.
const FormikAddressField = ({ label, onAddressUpdate, ...props }: any) => {
const [field, meta] = useField(props);
const loader = new Loader({
apiKey: process.env.REACT_APP_GOOGLE_MAP_API_KEY!,
libraries: ["places", "geometry"],
});
const locationInputId = "locationInputId";
let searchInput: HTMLInputElement;
const autoCompleteInstanceRef = React.useRef<any>(null);
React.useEffect(() => {
loader.load().then(() => {
let searchInput = document.getElementById(
locationInputId
) as HTMLInputElement;
//console.log(searchInput);
autoCompleteInstanceRef.current = new google.maps.places.Autocomplete(
searchInput!,
{
// restrict your search to a specific type of resultmap
//types: ["address"],
// restrict your search to a specific country, or an array of countries
// componentRestrictions: { country: ['gb', 'us'] },
}
);
autoCompleteInstanceRef.current.addListener(
"place_changed",
onPlaceChanged
);
});
// returned function will be called on component unmount
return () => {
google.maps.event.clearInstanceListeners(searchInput!);
};
}, []);
const onPlaceChanged = () => {
const place: google.maps.places.PlaceResult =
autoCompleteInstanceRef.current.getPlace();
if (!place) return;
onAddressUpdate(place.formatted_address);
};
return (
<>
<label htmlFor={props.id || props.name} className="form-label">
{label}
</label>
<Field
id={locationInputId}
className="text-md w-full h-full m-0 p-0"
type="text"
{...field}
{...props}
/>
{meta.touched && meta.error ? (
<div className="error">{meta.error}</div>
) : null}
</>
);
};
export default FormikAddressField;
CodeSandbox
Here is a simplified version: https://nv1m89.csb.app/
The EditStoreInfoPage is above the EditStoreInfoForm. The formikValues in EditStoreInfoPage appears to be a copy, which is not updated every time the actual real-time formik values in EditStoreInfoForm are changed. Your real problem here is that you shouldn't have the clone in the first place.
Just pass the real store values up to the handler:
<FormikAddressField
label="Store Location"
name="storeLocation"
onAddressUpdate={(newAddress) => props.handleStoreLocationUpdate(newAddress, formValues)}
placeholder={props.formValues?.storeLocation}
/>
Now change:
const handleStoreLocationUpdate = (newStoreLocation: string) => {
To:
const handleStoreLocationUpdate = (newStoreLocation: string, formValues: StoreAttributes) => {
And use that argument.
As mentioned there are other issues here. Really you should refactor to get rid of this completely:
const [formValues, setFormValues] = React.useState<StoreAttributes>({
storeName: "",
storeLocation: "",
storeLocationLongitude: 0,
storeLocationLatitude: 0,
});
You'd do it by making the actual form state accessible to that component. Probably by changing to the useFormik pattern and loading that hook in the parent.

react state cant delete first letter

I have this code that edit data, it works properly when adding text but removing all letters will not remove first letter.
export const Edit = (props: any) => {
const { initial } = usefetchEditUserType(props)
return (
<>
<CreateUpdate
title="Edit User Type"
useMutationHooks={useEditRole(props.id)} /** Change this */
editPermission={true}
value={initial} -->
id={props.id}
/>
<ListAssignUserAccount {...props} />
</>
);
};
CreateUpdate
const { inputValidation, handleOnChange, handleOnClickSubmit, data } = useMutationHooks;
<CardContent >
<TextField
required
//...omitted code
onChange={(e: any) => handleOnChange(e)}
error={inputValidation['input']}
helperText={inputValidation['input'] ? "Required*" : ""}
value={ data ? data : value } --> value from Edit component
/>
</CardContent>
useEditRole
export const useEditRole = (id: number) => {
const notify = useNotify()
const [inputValidation, setInputValidation] = useState({input: false, button: true})
const [data, setData] = useState("")
const handleOnClickSubmit = async () => {
await fetchCreateRole(data, "PUT", id).then((res: any) => {
notify("Successfully Updated!")
});
}
const handleOnChange = (e: any) => {
if(e.target.value) {
setData(e.target.value )
setInputValidation({ input: false, button: false})
} else {
setInputValidation({ input: true, button: true})
}
}
return { inputValidation, handleOnChange, handleOnClickSubmit, data, setData }
}
console logging seems working but in text field is not getting the changes input status. Im trying way another but then deleting in input field brings back the original or the default value

React set default value from Select List after load

I have a form that has a select list of countries and a cascading select list of regions. When a new country is selected, the corresponding regions are loaded. I am trying to set the value for the region after the the select list loads as the first value in the list. On page render I am loading the country select list here:
useEffect(() => {
fetchCountries();
}, []);
When a new country is selected, I am triggering the corresponding regions to be loaded here:
useEffect(() => {
fetchRegions();
regionData.length && setInput({...input, ["region"]: regionData[0].value})
}, [input["country"]]);
This is also where I am trying to set the default region value as the first item in the list, but the state is not being updated. Where have I gone wrong? More code below, with non-relevant code removed for brevity.
export default function Signup() {
const initialInput: SignupRequest = {
country: "US",
region: ""
};
const initialErrors: ValidationError = {
country: "",
region: ""
};
const [input, setInput] = useState<SignupRequest>(initialInput);
const [errors, setErrors] = useState<ValidationError>(initialErrors);
const [countryData, setCountryData] = useState<SelectListModel["data"]>([]);
const [countryLoaded, setCountryLoaded] = useState<boolean>(false);
const [regionData, setRegionData] = useState<SelectListModel["data"]>([]);
const [regionLoaded, setRegionLoaded] = useState<boolean>(false);
useEffect(() => {
fetchCountries();
}, []);
useEffect(() => {
fetchRegions();
regionData.length && setInput({...input, ["region"]: regionData[0].value})
}, [input["country"]]);
function handleSelectChange(event: React.ChangeEvent<HTMLSelectElement>) {
const { name, value } = event.target;
setInput({ ...input, [name]: value });
}
function handleBlur(event: React.ChangeEvent<HTMLInputElement | HTMLSelectElement>) {
const { name, value } = event.target;
validateInput(name, value);
}
function validateInput(name: string, value: string | string[] | boolean) {
let result = ValidationService.ValidateInput(name, value);
setErrors({ ...errors, [name]: result });
}
function handleFormSubmit(event: React.FormEvent<HTMLFormElement>) {
// process form
}
async function fetchCountries() {
const response = await LocationService.getAllCountries();
if (response?.ok) {
const responseData = await response.json() as CountryResponse[];
const countries = LocationService.maptoCountrySelectList(responseData);
setCountryData(countries);
setCountryLoaded(true);
}
}
async function fetchRegions() {
const response = await LocationService.getRegionsByCountryCode(input["country"]);
if (response?.ok) {
const responseData = await response.json() as RegionResponse[];
const regions = LocationService.maptoRegionSelectList(responseData);
setRegionData(regions);
setRegionLoaded(true);
}
}
return (
<div className="account-content">
<form onSubmit={handleFormSubmit}>
<FormGroup addClass='form-group'>
<Label label='country' title='Country' />
{!countryLoaded
? <LoadingSpinner text="Loading..." />
: <SelectList data={countryData} name='country' value={input["country"]} addClass={countryLoaded && errors["country"] ? 'is-invalid' : ''} onChange={handleSelectChange} onBlur={handleBlur} />}
<FormError message={errors["country"]} />
</FormGroup>
<FormGroup addClass='form-group'>
<Label label='region' title='State/Region/Province' />
{!regionLoaded
? <LoadingSpinner text="Loading..." />
: <SelectList data={regionData} name='region' value={input["region"]} addClass={regionLoaded && errors["region"] ? 'is-invalid' : ''} onChange={handleSelectChange} onBlur={handleBlur} />}
<FormError message={errors["region"]} />
</FormGroup>
<Button type='submit' value='Sign Up' addClass='btn-mdBlue' />
</form>
</div>
)
}
You need to setInput for region inside your fetchRegions function because setState is not synchonous so when you setRegion, and right after you setInput, region is still empty, on next render region gets filled with your previous setRegion but useEffect has already been run
const fetchRegions = async () => {
const regions = await // fetchsomething
setRegions(regions);
setInput({ ...input, region: regions[0].value });
}

Set value to textfield with hooks and redux material ui

I'm building an app using react, redux, and redux-saga.
The situation is that I'm getting information from an API. In this case, I'm getting the information about a movie, and I will update this information using a basic form.
What I would like to have in my text fields is the value from the object of the movie that I'm calling form the DB.
This is a brief part of my code:
Im using 'name' as an example.
Parent component:
const MovieForm = (props) => {
const {
movie,
} = props;
const [name, setName] = useState('');
const handleSubmit = (e) => {
e.preventDefault();
onSubmit({
name,
});
};
const handleSetValues = () => {
console.log('hi');
console.log(movie, name);
setName(movie.name);
setValues(true);
};
useEffect(() => {
if (movie && values === false) {
handleSetValues();
}
});
return (
<Container>
<TextField
required
**defaultValue={() => {
console.log(movie, name);
return movie ? movie.name : name;
}}**
label='Movie Title'
onChange={(e) => setName(e.target.value)}
/>
</Container>
);
};
export default MovieForm;
....
child component
const MovieUpdate = (props) => {
const { history } = props;
const { id } = props.match.params;
const dispatch = useDispatch();
const loading = useSelector((state) => _.get(state, 'MovieUpdate.loading'));
const created = useSelector((state) => _.get(state, 'MovieUpdate.created'));
const loadingFetch = useSelector((state) =>
_.get(state, 'MovieById.loading')
);
const movie = useSelector((state) => _.get(state, 'MovieById.results'));
useEffect(() => {
if (loading === false && created === true) {
dispatch({
type: MOVIE_UPDATE_RESET,
});
}
if (loadingFetch === false && movie === null) {
dispatch({
type: MOVIE_GET_BY_ID_STARTED,
payload: id,
});
}
});
const updateMovie = (_movie) => {
const _id = id;
const obj = {
id: _id,
name: _movie.name,
}
console.log(obj);
dispatch({
type: MOVIE_UPDATE_STARTED,
payload: obj,
});
};
return (
<div>
<MovieForm
title='Update a movie'
buttonTitle='update'
movie={movie}
onCancel={() => history.push('/app/movies/list')}
onSubmit={updateMovie}
/>
</div>
);
};
export default MovieUpdate;
Then, the actual problem is that when I use the default prop on the text field the information appears without any problem, but if i use defaultValue it is empty.
Ok, I kind of got the answer, I read somewhere that the defaultValue can't be used int the rendering.
So I cheat in a way, I set the properties multiline and row={1} (according material-ui documentation) and I was able to edit this field an receive a value to display it in the textfield

How can I update component whenever typing in input tag in React?

What the below code does is to get data from API, and then render it on the page. searchChange function takes a value from the input tag, and setValue for query state. My api endpoint takes argument to filter the API such as http://127.0.0.1:8000/api/deals/?q=${query}.
I'm very confused how I can update the DealList component with the API updated with query state whenever typing something in the input tag. I'm thinking of that I need to something in searchChange function, but not sure what to do there.
index.js
const useFetch = (url, query, defaultResponse) => {
const [result, setResult] = useState(defaultResponse);
const getDataFromAPI = async url => {
try {
const data = await axios.get(url);
setResult({
isLoading: false,
data
});
} catch (e) {}
};
useEffect(() => {
if (query.length > 0) {
getDataFromAPI(`${url}?q=${query}`);
} else {
getDataFromAPI(url);
}
}, []);
return result;
};
const Index = ({ data }) => {
const query = useInput("");
const apiEndpoint = "http://127.0.0.1:8000/api/deals/";
const dealFetchResponse = useFetch(apiEndpoint, query, {
isLoading: true,
data: null
});
const searchChange = e => {
query.onChange(e);
query.setValue(e.target.value);
};
return (
<Layout>
<Head title="Home" />
<Navigation />
<Container>
<Headline>
<h1>The best lease deal finder</h1>
<h4>See all the lease deals here</h4>
</Headline>
<InputContainer>
<input value={query.value} onChange={searchChange} />
</InputContainer>
{!dealFetchResponse.data || dealFetchResponse.isLoading ? (
<Spinner />
) : (
<DealList dealList={dealFetchResponse.data.data.results} />
)}
</Container>
</Layout>
);
};
export default Index;
The biggest challenge in something like this is detecting when a user has stopped typing.. If someone is searching for 'Milk' - when do you actually fire off the API request? How do you know they aren't searching for 'Milk Duds'? (This is hypothetical, and to demonstrate the 'hard' part in search bars/APIs due to their async nature)..
This is typically solved by debouncing, which has been proven to work, but is not very solid.
In this example, you can search Github repos...but even in this example, there are unnecessary requests being sent - this is simply to be used as a demonstration. This example will need some fine tuning..
const GithubSearcher = () => {
const [repos, setRepos] = React.useState();
const getGithubRepo = q => {
fetch("https://api.github.com/search/repositories?q=" + q)
.then(res => {
return res.json();
})
.then(json => {
let formattedJson = json.items.map(itm => {
return itm.name;
})
setRepos(formattedJson);
});
}
const handleOnChange = event => {
let qry = event.target.value;
if(qry) {
setTimeout(() => {
getGithubRepo(qry);
}, 500);
} else {
setRepos("");
}
};
return (
<div>
<p>Search Github</p>
<input onChange={event => handleOnChange(event)} type="text" />
<pre>
{repos ? "Repo Names:" + JSON.stringify(repos, null, 2) : ""}
</pre>
</div>
);
};
ReactDOM.render(<GithubSearcher />, document.body);
