How can I send multiple objects in axios ? is there a way to send an array to an API using axios ?
This is the code.
export const addOrderAdmin = (ownerID,array) => api.patch(`/checkout/${ownerID}`,
{
delivery: array // array with 2 objects.
}
)
and the objects was like this.
is it possible ?
you could always create an array of nested objects
example:
var customerInfo = {
name: 'bob',
phone : 'xxx-xxx-xxxx',
address: [
{
id: 1,
city: 'Buffalo'
},
{
id 2,
city: 'Houston'
]
}
then you could just patch the customerInfo object and you can use interpolation with dot accessor notation for the url

I'm new in angular and I need some help.
I have an observable getting users of type User[]
User: [
id: string,
name: string
]
and I have another array Ids of type string getting the ids of the selected users from a mat-select
Ids = this.Form.controls['users'].value
what I need right now is to subscribe to users$ observable, and get only the users that they have an id in Ids
const selectedUsers = ids.forEach(id =>this.usersSub$.value.filter((user) => user.userId === id))
something like the above but it is not really the right thing to do because it returns undefined . I'm wondering how should I properly get my selectedUsers array.
You use combineLatest to merge both observables and map all elements to accomplish it.
First, Create an observable with ids.
selectedIds$ = of([1, 3]);
players$ = of([
{ id: 1, name: 'lebron' },
{ id: 2, name: 'irving' },
{ id: 3, name: 'love' },
]);
Next, combine both observables, using the combineLatest operator, and return the players using the map to iterate over the response from the combineLast, use the filter and find to match the playerid with the ids from the selectedIds array.
const seletedUsers$ = combineLatest([this.selectedIds$,
this.players$])
.pipe(
map(([ids, players]) => {
return players.filter((p) => ids.find((id) => id === p.id));
})
)
.subscribe((v) => {
console.log(v);
});

and thanks for your attention and help,
I have a Collection in my livewire controller. This collection contains a list of players, with some properties : here we will just focus on id and name.
So we can imagine that we have 3 players in the collection :
Players[0] : 'id'=>1, 'name'=>'Yann';
Players[1] : 'id'=>2, 'name'=>'Robert';
Players[2] : 'id'=>3, 'name'=>'Jessica';
I need to get these players in my alpine data.
I can easily get these players in Alpine with the #js method :
window.addEventListener('alpine:init', () => {
Alpine.data('data', () => ({
players: #js($players),
}))
})
So, now I have in my alpine.data :
players: [
{ id: 1, name: 'Yann' },
{ id: 2, name: 'Robert' },
{ id: 3, name: 'Jessica' },
]
Now I can easily display the players in my html with a template x-for :
<template x-for="player in players">
<p x-text="player.name"></p>
</template>
But I want to add some additionnal properties in each player object. Those properties will be updated in front depending user's actions.
I would like to get something like this :
players: [
{ id: 1, name: 'Yann', touched20: 0, touched15: 0 },
{ id: 2, name: 'Robert', touched20: 0, touched15: 0 },
{ id: 3, name: 'Jessica', touched20: 0, touched15: 0 },
]
All additionnal properties are the same for each object in the array, so I imagine i could use a foreach loop to put them in the objects.
But I can't see and don't understand how i can include a loop in my alpine.data script to do this.
Anyone could help me ?
I edit my question because I found a solution :
I just make a loopPlayers function outside of my alpine data and call this function in the alpine data :
function loopPlayers() {
let players = [];
const livewirePlayers = #js($players);
livewirePlayers.forEach(element => {
players.push(element);
});
players.forEach(function(element) {
element.touched15 = 0;
})
return players;
}
And in alpine.data :
players: loopPlayers(),
Now I have my collection of players from my livewire controller & I have new properties for each element of the collection in the js data
That was easy, as usual I guess :)
I want to find a value inside an array that is already inside an array.
To give an example of my array:
[
{
ConcessionId: 1,
ConcessionName: "Coyotes",
KnownAs: [
{
TeamId: 1,
Name: "Arizona Coyotes",
},
{
TeamId: 2,
Name: "Phoenix Coyotes",
}
]
},
{
ConcessionId: 2,
ConcessionName: "Devils",
KnownAs: [
{
TeamId: 3,
Name: "Colorado Rockies",
},
{
TeamId: 4,
Name: "New-Jersey Devils",
}
]
}
]
What I want is when Icall my function it returns me the team name.
For example, I the parameter value is 3, I want Colorado Rockies as a name:
public getInfo(_TeamID) {
const concession: ConcessionInfo[] = this.concessionList$.filter(function (x) {
x.KnownAs.filter( (y)=> {
y.TeamId= +_TeamID;
return y.Name;
})
})
}
I try so many different way with filter. But never get something good. Never works.
I can make a double .foreach , for each array. but I think a better method exist than making a double loop.
Thanks
Instead of using the filter method (which is in fact working similar as a for loop), you could do forEach on both arrays. For your current data structure, there is no other way around it.
getInfo = (_TeamID) => {
let teamName = '';
this.concessionList$.forEach(entry => {
entry.KnownAs.forEach(team => {
if(team.TeamId === _TeamID){
teamName = team.Name;
return; // break the loop.
}
})
});
return teamName;
}
Here is a working example

EDIT
If you have a look at the polyfill implementation of filter from Mozilla https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/filter which is in equivalent to the native implementation of filter, you can see that it is looping through the whole array, the same way as a forEach loop. The difference is that the filter method will return a new array based on the boolean condition inside the callback function, while a forEach loop does not return anything.
Assuming myArray is contains the data you provided.
The following code will work if you're using Typescript 3.7 and above.
public getInfo(teamId: number): string | undefined {
const team = this.concessionList$
.map(concession => concession.KnownAs)
.reduce((a, b) => a.concat(b), [])
.find(team => team.TeamId === teamId)
return team ? team.Name : undefined
}
Usage:
this.getInfo(3) // Colorado Rockies
Ok how this work?
You have to understand what is find. For example:
const result = [{name: 'foo', age: 1}, {name: 'bar', age: 2}]
.find(people => people.name === 'foo')
console.log(result) // {name: 'foo', age: 1}
Given a list:
let names = [{name: "bobby"}, {name: "sydney"}, {name: "Paul"}, {name: "Grace"}
I want the output to be ["bobby", "sydney", "Paul", "Grace"]
Here is what I have tried:
var items = Object.keys(names).map(function(i) {
return names[i];
})
const items = Object.keys(names).map((key)=>names[key]);
this.setState({items});
console.log(this.state.items);
names.map(({ name }) => name)
const names = [{
name: "bobby"
}, {
name: "sydney"
}, {
name: "Paul"
}, {
name: "Grace"
}];
const keys = names.map(({
name
}) => name);
console.log(keys);
A note about react keys, they should be unique within the rendered siblings, i.e. they should be unique within the dataset. Names alone may not provide sufficient uniqueness.
A second note, you might not want to generate your react keys separately from where you need them, i.e. generally they are created when you are mapping JSX.
This is not really related to React. You can do that with JavaScript, for instance using API like map().
Here is an example:
let arr = names.map(obj => obj.name);
I have object in redux store
`{455:{id:'455',name'test'},456:{id:'456',name:'test2},457:{id:'457',name'test3'},...}`.
At now I iterate values with method Object.keys. Have any more elegant method for this case?
Many Thanks.
In stead of using Object.keys to map over the object, you can use Object.values() that returns an array of values and then map over them like
var obj = {
'455': {
id: '455',
name:'test'
},
'456': {
id: '456',
name: 'test2'
},
'457': {
id: '457',
name:'test3'
}
}
Object.values(obj).map((val) => console.log(val))
