useCreate

useCreate is a modified version of react-query's useMutation for create mutations.

It uses create method as mutation function from the dataProvider which is passed to <Refine>.

Features

• Shows notifications after the mutation succeeds or fails.

• Automatically invalidates the list queries after mutation is succesfully run. Refer to React Query docs for detailed information →

Usage

Let'say we have a resource named categories

https://api.fake-rest.refine.dev/categories

{
    [
        {
            id: 1,
            title: "E-business",
        },
        {
            id: 2,
            title: "Virtual Invoice Avon",
        },
        {
            id: 3,
            title: "Unbranded",
        },
    ];
}

type CategoryMutationResult = {
    id: number;
    title: string;
};

import { useCreate } from "@pankod/refine-core";

const { mutate } = useCreate<CategoryMutationResult>();

mutate({
    resource: "categories",
    values: {
        title: "New Category",
    },
});

提示

mutate can also accept lifecycle methods like onSuccess and onError.

mutate(
    {
        resource: "categories",
        values: {
            title: "New Category",
        },
    },
    {
        onError: (error, variables, context) => {
            // An error happened!
        },
        onSuccess: (data, variables, context) => {
            // Let's celebrate!
        },
    },
);

Refer to react-query docs for further information. →

After the mutation runs, categories will be updated as below:

https://api.fake-rest.refine.dev/categories

{
    [
        {
            id: 1,
            title: "E-business",
        },
        {
            id: 2,
            title: "Virtual Invoice Avon",
        },
        {
            id: 3,
            title: "Unbranded",
        },
        {
            id: 4,
            title: "New Category",
        },
    ];
}

备注

Queries that use /categories endpoint will be automatically invalidated to show the updated data. For example, data returned from useList will be automatically updated.

提示

useCreate returns react-query's useMutation result which includes a lot properties, one of which being mutate.

警告

Variables passed to mutate must have these types.

{
    resource: string;
    values: TVariables = {};
}
