I would like to see if there is a way to prevent a refresh and use the hook "useUpdate" in React-Admin.
Use case would be I am emplimenting a auto save feature for my form and save it on the back end.
I'm currently using useUpdate but with the nature of my form, a reload would not be a good UI because the form could be 50-100 fields long. So a user could be editing a field close to the end and auto save will send them back to the top of the page.
I still want to use the data provider. Currently this is only being used to Edit a record

I want to be able to validate the entire form and get the validation result, but I want to do it 'silently'(i.e without making my fields go red). I know that formContext.trigger exists, but that doesn't seem to have a softer setting. I don't want to show errors to the user, I just want to check if what they have got so far is valid. Is this possible with react hook form?
Context:
I'm using 'onChange' mode for my form
I need to do this because as a user fills my form in, which is for a pricing page, I want to send requests to get the pricing information which changes based on the form data. I don't want to send a pricing request if the form isn't valid, but I don't want to trigger full validation and make the fields go red when the user hasn't done anything wrong, they're just filling the form out in order.
I am making a web app in which I have a section which has an input field. Anything that is submitted through the input field gets posted to an API. So when you land on that screen you see all the previous inputs made. What I am not able to figure out is and the thing I want to achieve is that when someone submits a new input it doesn't reflect in UI until and unless you go back and come back to the screen. I want that as soon as you send an input the input string should be reflected in the UI. How can this be done using AngularJS?
You have two options, at a very basic level they are:
1) The first is to re-query all the list when the item is saved:
api.save(newPost).then(() => getAllPosts());
2) You can return the recently saved post and add it to the list:
api.save(newPost).then((saved) => $scope.posts.push(saved));
You'll need to handle all the unwrapping (etc) based on how you're making the calls.
We have a web app composed of several pages containing links of data retrieved from database. Upon clicking one link[data], the user should be directed to another page. For navigation between pages, we have used breadcrumb. The breadcrumb is stored in redux store. Currently, when the user tries to ctrl+click or open link in new tab, we managed to use single store across multiple tabs. Hence, if the user opens 3 separate links [data] in new tabs, the updates made on the breadcrumb affect previously opened tabs when these tabs/pages are refreshed. For example:
In homepage, I have these links:
Data_1
Data_2
Data_3
Current breadcrumb in the homepage is like this:
HomePage/
Once the user opens Data_1 in new tab, the expected breadcrumb in the new tab is:
HomePage/Data_1/
Similarly, if the user tries to open Data_2 and Data_3, in new tabs, the breadcrumbs should appear as follows for tab 1 and tab 2, respectively:
HomePage/Data_2/
HomePage/Data_3/
In the current implementation, I managed to update the state of breadcrumb whenever new links are opened such that breadcrumb[0] would be equivalent to HomePage while breadcrumb[1] was initially Data_1, then became Data_2, and lastly Data_3. Hence, the last value of breadcrumb[1] is Data_3 since that's the last opened link. My problem is that whenever the user refreshes previously opened tabs/pages corresponding to Data_1 and Data_2, since they are all using a single store and breadcrumb[1] has been changed to Data_3, the breadcrumbs in Data_1 and Data_2 pages also become Data_3.
In this case, I can just think of using multiple stores since I perceive that it could be the only solution given my use case. Meanwhile, I can't find any sufficient documentation online regarding using multiple stores in redux. Maybe I can pass the store to the next page in params...? something like that
Can someone please help. Thanks in advance.
To emulate per-tab same site persistency, I would, right before the page is about to be refreshed (window.beforeunload or similar)
1 - Write to localStorage about my breadcrumb
2 - Refresh
3 - Read from localStorage about my breadcrumb to initialize myself properly (so the data here SHOULD be mine because i just wrote it)
4 - remove breadcrumb information from localStorage (to prevent other tabs from reading it)
Now, you still have the case where the user just closes the tab, so you would have stale data about the breadcrumb in your localStorage. You can add a little expiration mechanism (you might consider that data in the localStorage older than 10 seconds is stale and just pretend it isn't here and delete it at step 3.) Cookies would work pretty much the same, with a built-in expiration mechanism.
React router has very cool feature: if you have a list of items (Instagram for example) and if you click on one item, content opens in modal/overlay but if you copy-paste the link to new tab/window or share the link with a friend for example, it opens in its own page.
I would love to use this feature but I need to find a custom solution..
My posts are very data heavy
I've split posts data into 2 tables in database
1st is very lightweight containing essential data: 4-5 columns
2nd table is very heave, ~30 columns
When user uses search filter, list updates only with data from 1st table
If user clicks on post, it will open in a modal/overlay
I will recycle the data I already have (from 1st table) and also get rest of the data from 2nd table
However, when user shares the link or opens it in new tab/page, data from 1st table is not present. I would need to integrate a conditional logic:
If post opens in list view (modal/overlay), only get additinal 2nd table data
If it's opened in a new tab/window in its own page, get all the data, 1st table included
How could I integrate this with React router? Has anyone already tried it? This would also allow to use different layout/components when user opens item in page view. Is there a way to check it?
Or is there a flaw in my logic? I imagine list would update very fast because it doesn't require huge amount of data and also would modal/overlay because it recycles some of the data.
I read all the docs, also searched online - didn't find anything.
Modals in react router are great. I've used the pinterest example and adapted it to my own needs.
Ensure you do your check on state.modal===true in a master layout component to give you the modal styling.
you'll need to check if table 1 stuff is present in your state and dispatch an action to trigger the async call in componentDidMount. You should be fetching table 2 in all scenarios.
I have a form that I'm using to enter data.
I'm calling the Create action using an invoke action on refresh set on ifNeeded.
The problem I have is that when I try to navigate away with empty fields the form validation stops me from doing so.
I know the Create action shouldn't be doing this as Oracle changed that to CreateInsert but I think this is because one of the entity object attributes is of type DBSequence and to my knowledge that sets a dummy value of -1 until the db trigger changes it.
What can I do to enable the user to leave the page empty and navigate away?
Set immediate to true.
