Hi @alfaz_muhammed. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:

Refine provides a hook called
useForm
that you can use to modify the form data before it is submitted to the API. When you use the useForm
hook with action: "edit"
, it fetches the record data according to the id
with useOne
and returns the queryResult
for you to fill the form. After the form is submitted, it updates the record with useUpdate
.
Here is an example of how to use useForm
with action: "edit"
:
In this example, the useForm
hook is used to handle the form submission. The register
function from useForm
is used to register input/select fields in the form. The handleSubmit
function is used to handle form submission. The onFinish
function is used to handle the form submission event.
You can modify the data in the onFinish
function before it is submitted to the API. For example, you can modify the title
and content
fields like this:
For more information, you can refer to the useForm documentation (https://refine.dev/docs/api-reference/core/hooks/useForm).
Please note that this is a general guide and the actual implementation may vary depending on your specific requirements and the structure of your application.

@kapa.ai Iam handling all the form submission, in my Autocomplete, I want to modify only the data refine fills when Edit page loads only at initial time. iam modifying data on onChange and form submission but at initial render of the page, when refine fills the data, I want to modify only there
Let me check the knowledge base for you. One moment! :books:
----------------------
Refine does not provide a direct way to modify the initial data that is filled when the Edit page loads. The data is fetched and filled based on the
id
of the record using the useOne
hook.
However, you can create a workaround by using a state in your component to track the initial render and modify the data accordingly. Here's a general idea of how you can do it:
In this example, we're using a state initialRender
to track if it's the first render. When the component mounts, if it's the initial render and the form data is available, we modify the data using the setValue
method from formMethods
and then set initialRender
to false
.

Hey @alfaz_muhammed,
You can use
useForm
's queryOptions.select
props. Like this:

@kapa.ai the code you given works,
seEffect(() => {
if (initialRender && formState?.data) {
// Modify the data here
formMethods.setValue('yourFieldName', 'yourModifiedValue');
setInitialRender(false);
}
}, [formState, formMethods, initialRender]);
this code works at initial render and it resetValue the id but in the edit page, we have Refresh button, if I click that the data reloads and value go back to before I want my useEffect works there also
Let me check the knowledge base for you. One moment! :books:
----------------------
The Refresh button in Refine triggers the
useOne
hook to fetch the data again. To modify the data when the Refresh button is clicked, you can add a dependency to the useEffect
hook to listen for changes in the formState.data
object. This will cause the useEffect
hook to run whenever the data is refreshed.
Here's how you can modify the code:
In this example, the useEffect
hook will run whenever formState.data
changes, which includes when the Refresh button is clicked and the data is re-fetched.
Please note that this is a general guide and the actual implementation may vary depending on your specific requirements and the structure of your application.

@kapa.ai there is no prop 'data' from formState
Let me check the knowledge base for you. One moment! :books:
----------------------
I apologize for the confusion. You're correct,
formState
does not have a data
property. The formState
object contains information about the form state like errors
and isSubmitted
.
The data fetched by useOne
hook is available in the queryResult
object. You can use queryResult.data
to access the fetched data.
Here's how you can modify the code:
In this example, the useEffect
hook will run whenever queryResult.data
changes, which includes when the Refresh button is clicked and the data is re-fetched.
Please note that this is a general guide and the actual implementation may vary depending on your specific requirements and the structure of your application.

@kapa.ai this works fine but one problem also. if i go to list page and come back to edit page without , the data seem to be going to old form how to handle there
Let me check the knowledge base for you. One moment! :books:
----------------------
The issue you're facing might be due to the fact that the
queryResult.data
object is not being updated when you navigate away from the Edit page and then come back. This could be because the useOne
hook is not being triggered again, and so the old data is still being used.
One way to handle this is to reset the form when the Edit page unmounts. You can do this by returning a cleanup function from the useEffect
hook that calls the reset
method from formMethods
. Here's how you can modify the code:
In this example, the useEffect
hook will run a cleanup function that resets the form when the Edit page unmounts. This should ensure that the old data is not used when you navigate back to the Edit page.
