Hmm, I don't know enough to give you a confident answer yet. However, based on the information provided, it seems like you might not have connected your form instance created by
useForm
to any Form element. This is usually done by passing the form
prop to the Form element.
Here's a basic example of how to use useForm
in refine:
And then you would add an onSubmit
event handler to the form and pass the handleSubmit
method and formSubmission
function to it:
For more detailed information, you might want to check the refine documentation (https://refine.dev/docs/packages/documentation/react-hook-form/useForm) or the React Hook Form documentation (https://react-hook-form.com/get-started).

"Forget to pass 'form' prop?" -> No, so this i why I don't understand
@kapa.ai read again please
Let me check the knowledge base for you. One moment! :books:

The warning you're seeing typically indicates that the form instance created by
useForm
is not connected to any Form element. This is usually done by passing the form
prop to the Form element.
In the context of refine, useForm
is a hook used to manage forms. It returns the necessary properties and methods to control the form. Here's a basic usage of the useForm hook from the refine blog (https://refine.dev/blog/react-hook-form-validation-examples):
You should ensure that the form instance returned by useForm
is connected to your Form element. If you're using a library like Ant Design, you would typically pass the form
instance as a prop to the Form
component.
If you're still having trouble, I would recommend referring to the documentation for the specific useForm
hook you're using in refine, whether it's the Ant Design version (https://refine.dev/docs/api-reference/antd/hooks/form/useForm), the Mantine version (https://refine.dev/docs/api-reference/mantine/hooks/form/useForm), or the React Hook Form version (https://refine.dev/docs/examples/form/react-hook-form/useForm).

@kapa.ai that's already what I do with {...formProps}
Let me check the knowledge base for you. One moment! :books:
----------------------
The
formProps
returned by the useForm
hook in refine is used to manage the state and actions of the Ant Design <Form>
component. It should be spread into the <Form>
component as you're doing with {...formProps}
.
Here's an example from the refine documentation (https://refine.dev/docs/api-reference/antd/hooks/form/useForm):
In this example, formProps
is spread into the <Form>
component, which connects the form instance created by useForm
to the Form element.
If you're seeing a warning about the instance created by useForm
not being connected to any Form element, it could be due to a variety of reasons. It's possible that there's an issue with the way your form is set up, or there could be a problem with the useForm
hook itself.
Without more information about your specific setup, it's difficult to provide a more precise answer. I would recommend checking your form setup and ensuring that you're correctly using the useForm
hook as per the refine documentation.

@kapa.ai please read carefully my code and tell me why i have this error :
I literally connect my form instance to the form but I still get this error
Let me check the knowledge base for you. One moment! :books:
----------------------
Your code seems correct at first glance. You're correctly spreading
formProps
into the Form
component, which should connect the form instance created by useForm
to the Form element.
However, the issue might be related to the useEffect
hook where you're calling form.resetFields()
and form.setFieldsValue({})
. These calls might be causing the form to lose its connection with the useForm
instance.
Try removing or commenting out the useEffect
block and see if the warning persists:
If the warning disappears, then the issue is likely with how the useEffect
hook is interacting with the form. If the warning persists, then the issue might be elsewhere in your code or it could be a bug with the useForm
hook itself.
If you're still having trouble, I would recommend checking the refine documentation (https://refine.dev/docs/api-reference/antd/hooks/form/useForm) or seeking help from the refine community or support channels.
