---------------------- 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:
const {
control,
handleSubmit,
watch,
formState: { errors },
} = useForm <IFormValue>
{
mode: "onChange",
defaultValues,
resolver: yupResolver(schema),
};

const handleSubmission = (data: any) => console.log(data);
const {
control,
handleSubmit,
watch,
formState: { errors },
} = useForm <IFormValue>
{
mode: "onChange",
defaultValues,
resolver: yupResolver(schema),
};

const handleSubmission = (data: any) => console.log(data);
And then you would add an onSubmit event handler to the form and pass the handleSubmit method and formSubmission function to it:
<form
onSubmit={handleSubmit(formSubmission)}
style={{ display: "flex", flexDirection: "column" }}
>
...
</form>
<form
onSubmit={handleSubmit(formSubmission)}
style={{ display: "flex", flexDirection: "column" }}
>
...
</form>
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). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

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):
const {
control,
handleSubmit,
watch,
formState: { errors },
} = useForm({
mode: "onChange",
defaultValues,
});
const {
control,
handleSubmit,
watch,
formState: { errors },
} = useForm({
mode: "onChange",
defaultValues,
});
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). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@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):
import { Edit, useForm } from "@refinedev/antd";
import { Form, Input } from "antd";

const PostEdit: React.FC = () => {
const { formProps, saveButtonProps } = useForm<IPost>();

return (
<Edit saveButtonProps={saveButtonProps}>
<Form {...formProps} layout="vertical">
<Form.Item
label="Title"
name="title"
rules={[
{
required: true,
},
]}
>
<Input />
</Form.Item>
</Form>
</Edit>
);
};
import { Edit, useForm } from "@refinedev/antd";
import { Form, Input } from "antd";

const PostEdit: React.FC = () => {
const { formProps, saveButtonProps } = useForm<IPost>();

return (
<Edit saveButtonProps={saveButtonProps}>
<Form {...formProps} layout="vertical">
<Form.Item
label="Title"
name="title"
rules={[
{
required: true,
},
]}
>
<Input />
</Form.Item>
</Form>
</Edit>
);
};
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. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai please read carefully my code and tell me why i have this error :
....
const { form, formProps, onFinish } = useForm<any>({
action: "create",
dataProviderName: PROVIDERS.LEARNING_LAB,
resource: process.env.REACT_APP_LOGIN_PATH!+`?${query}`
})

useEffect(() => {
form.resetFields();
form.setFieldsValue({});
}, [])

if(isLoadingAuths || isLoadingClients) return <></>

const handleFinish = (values: any) => {
onFinish(values)
.then(d => console.log(d))
.catch(() => {})
}

return (
<div className="container">
<ConfigProvider theme={{token: { colorPrimary: clientDetails?.color ?? "" }}}>
<Form name="connect" onFinish={handleFinish} {...formProps} size="large" className="form">
...
</Form>
</ConfigProvider>
</div>
)
....
const { form, formProps, onFinish } = useForm<any>({
action: "create",
dataProviderName: PROVIDERS.LEARNING_LAB,
resource: process.env.REACT_APP_LOGIN_PATH!+`?${query}`
})

useEffect(() => {
form.resetFields();
form.setFieldsValue({});
}, [])

if(isLoadingAuths || isLoadingClients) return <></>

const handleFinish = (values: any) => {
onFinish(values)
.then(d => console.log(d))
.catch(() => {})
}

return (
<div className="container">
<ConfigProvider theme={{token: { colorPrimary: clientDetails?.color ?? "" }}}>
<Form name="connect" onFinish={handleFinish} {...formProps} size="large" className="form">
...
</Form>
</ConfigProvider>
</div>
)
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:
// useEffect(() => {
// form.resetFields();
// form.setFieldsValue({});
// }, [])
// useEffect(() => {
// form.resetFields();
// form.setFieldsValue({});
// }, [])
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. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
