Hi @ansellmax. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- The data from onSuccess in the mutate function for useCreate could be returning undefined for a few reasons. One possible reason could be that the mutation was not successful. The onSuccess callback is only triggered after a successful mutation. If the mutation was not successful, the data would be undefined. Another possible reason could be related to how the useCreate hook is implemented. In the useCreate hook, the data is extracted from the response of the mutation. If the response does not contain the data field, then data would be undefined. Here is an example of how useCreate is used:
const { mutate } = useCreate();

mutate(
{
resource: "products",
values: {
name: "New Product",
material: "Wood",
},
},
{
onError: (error, variables, context) => {
// An error occurred!
},
onSuccess: (data, variables, context) => {
// Let's celebrate!
},
},
);
const { mutate } = useCreate();

mutate(
{
resource: "products",
values: {
name: "New Product",
material: "Wood",
},
},
{
onError: (error, variables, context) => {
// An error occurred!
},
onSuccess: (data, variables, context) => {
// Let's celebrate!
},
},
);
In the onSuccess callback, data should contain the response from the mutation. If it's undefined, it could be due to the reasons mentioned above. For more information, you can refer to the useCreate documentation (https://refine.dev/docs/api-reference/core/hooks/data/useCreate) and the useMutation documentation (https://tanstack.com/query/v4/docs/react/reference/useMutation). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

What's the standard way to create a document and get it after success? @kapa.ai What's the standard way to create a document and get it after success?

Let me check the knowledge base for you. One moment! :books: ---------------------- The standard way to create a document and get it after success in Refine is to use the useForm hook with the onFinish and redirect functions. After a successful mutation, useForm will redirect to the "list" page by default. However, you can programmatically specify a different destination using the redirect function. Here's an example of how you can create a document and then redirect to the "show" page of the newly created document:
const { onFinish, redirect } = useForm();

const handleSubmit = async (e: React.FormEvent<HTMLFormElement>) => {
e.preventDefault();
const data = await onFinish(formValues);
redirect("show", data?.data?.id);
};
const { onFinish, redirect } = useForm();

const handleSubmit = async (e: React.FormEvent<HTMLFormElement>) => {
e.preventDefault();
const data = await onFinish(formValues);
redirect("show", data?.data?.id);
};
In this example, onFinish is used to handle the form submission and perform the mutation. The redirect function is then used to redirect to the "show" page of the newly created document. The ID of the new document is accessed from the data returned by onFinish. For more information, you can refer to the useForm documentation (https://refine.dev/docs/api-reference/core/hooks/useForm). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai createMany onSuccess response's data object returns null

kapa.ai11mo ago
Let me check the knowledge base for you. One moment! :books: ---------------------- The data from onSuccess in the mutate function for useCreateMany could be returning null for a few reasons. One possible reason could be that the mutation was not successful. The onSuccess callback is only triggered after a successful mutation. If the mutation was not successful, the data would be null. Another possible reason could be related to how the useCreateMany hook is implemented. In the useCreateMany hook, the data is extracted from the response of the mutation. If the response does not contain the data field, then data would be null. Here is an example of how useCreateMany is used:
const { mutate } = useCreateMany();

mutate(
{
resource: "products",
values: [
{
name: "Product 1",
material: "Wood",
},
{
name: "Product 2",
material: "Metal",
},
],
},
{
onError: (error, variables, context) => {
// An error occurred!
},
onSuccess: (data, variables, context) => {
// Let's celebrate!
},
},
);
const { mutate } = useCreateMany();

mutate(
{
resource: "products",
values: [
{
name: "Product 1",
material: "Wood",
},
{
name: "Product 2",
material: "Metal",
},
],
},
{
onError: (error, variables, context) => {
// An error occurred!
},
onSuccess: (data, variables, context) => {
// Let's celebrate!
},
},
);
In the onSuccess callback, data should contain the response from the mutation. If it's null, it could be due to the reasons mentioned above. For more information, you can refer to the useCreateMany documentation (https://refine.dev/docs/api-reference/core/hooks/data/useCreateMany) and the useMutation documentation (https://tanstack.com/query/v4/docs/react/reference/useMutation). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai how do I crate pages that don't require auth
kapa.ai
kapa.ai11mo ago
Let me check the knowledge base for you. One moment! :books: ---------------------- To create pages that don't require authentication in Refine, you need to modify the authProvider.checkAuth() method. This method is used to determine if a user is authenticated or not. By tweaking this method, you can bypass authentication for specific paths. Here's an example of how you can do this:
const authProvider = {
// ...
checkAuth: () => {
if (window.location.pathname === '/public-path') {
return Promise.resolve();
}
// ... existing checkAuth implementation
},
// ...
};
const authProvider = {
// ...
checkAuth: () => {
if (window.location.pathname === '/public-path') {
return Promise.resolve();
}
// ... existing checkAuth implementation
},
// ...
};
In this example, if the current path is '/public-path', the checkAuth method immediately resolves the Promise, bypassing the authentication check. For more information, you can refer to the Refine documentation on customizing auth pages (https://refine.dev/docs/tutorial/understanding-authprovider/headless/auth-pages#customizing-auth-pages). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
