Trigger function when form loading is complete
Is there a way to have a custom function fire once a form has finished loading? Specifically for the ant design hook of useForm?

Hi @HypnoticMeat. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:
----------------------
To trigger a custom function once a form has finished loading using the Ant Design
useForm
hook in refine, you can utilize the formLoading
state. The formLoading
state is a boolean value that indicates the loading status of the form. By monitoring this state, you can execute your custom function when the form loading is complete.
Here is an example of how you can achieve this:
In this example, the useEffect
hook monitors the formLoading
state. When formLoading
changes to false
, indicating that the form has finished loading, the myCustomFunction
is executed.
For more information on formLoading
, you can refer to the documentation (https://refine.dev/docs/data/hooks/use-form#formloading).

@kapa.ai but that will fire myCustomFunction every time the component re-renders once the form loading is complete. I want the function to fire only a single time, when the form first finishes loading to do some initial setup. But not fire subsequently when other state management functions are called post form load.
Let me check the knowledge base for you. One moment! :books:

To ensure that your custom function fires only once when the form first finishes loading, you can use a combination of the
useEffect
hook and a state variable to track whether the function has already been executed. Here’s how you can do it:
In this example, the useEffect
hook checks both formLoading
and hasLoaded
. The custom function myCustomFunction
is called only if formLoading
is false
and hasLoaded
is false
. After the function is executed, setHasLoaded(true)
ensures that the function will not run again on subsequent re-renders.
This approach ensures that your custom function is triggered only once when the form first finishes loading, and not on subsequent state changes or re-renders.
