Hi @olafg. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- You can use raw GraphQL queries with the GraphQL data provider in Refine by using the gqlQuery and gqlMutation fields in the meta property. These fields accept a GraphQL operation as graphql's DocumentNode type. You can pass these queries or mutations to your data provider methods through data hooks like useOne, useList, useForm from anywhere across your application. Here's an example of how you can use raw GraphQL queries and mutations:
import gql from "graphql-tag";
import { useOne, useUpdate } from "@refinedev/core";

const GET_PRODUCT_QUERY = gql`
query GetProduct($id: ID!) {
product(id: $id) {
id
title
category {
title
}
}
}
`;

useOne({
resource: "products",
id: 1,
meta: {
gqlQuery: GET_PRODUCT_QUERY,
},
});

const UPDATE_PRODUCT_MUTATION = gql`
mutation UpdateOneProduct($id: ID!, $input: UpdateOneProductInput!) {
updateOneProduct(id: $id, input: $input) {
id
title
category {
title
}
}
}
`;

const { mutate } = useUpdate();

mutate({
resource: "products",
id: 1,
values: {
title: "New Title",
},
meta: {
gqlMutation: UPDATE_PRODUCT_MUTATION,
},
});
import gql from "graphql-tag";
import { useOne, useUpdate } from "@refinedev/core";

const GET_PRODUCT_QUERY = gql`
query GetProduct($id: ID!) {
product(id: $id) {
id
title
category {
title
}
}
}
`;

useOne({
resource: "products",
id: 1,
meta: {
gqlQuery: GET_PRODUCT_QUERY,
},
});

const UPDATE_PRODUCT_MUTATION = gql`
mutation UpdateOneProduct($id: ID!, $input: UpdateOneProductInput!) {
updateOneProduct(id: $id, input: $input) {
id
title
category {
title
}
}
}
`;

const { mutate } = useUpdate();

mutate({
resource: "products",
id: 1,
values: {
title: "New Title",
},
meta: {
gqlMutation: UPDATE_PRODUCT_MUTATION,
},
});
In this example, GET_PRODUCT_QUERY and UPDATE_PRODUCT_MUTATION are raw GraphQL queries and mutations respectively. They are passed to the useOne and useUpdate hooks through the gqlQuery and gqlMutation fields in the meta property. For more information, you can refer to the Data Fetching guide in the Refine documentation (https://refine.dev/docs/guides-concepts/data-fetching#graphql). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

I tried this, but the query sent to the API contains sort and where options which I did not specify @kapa.ai

Let me check the knowledge base for you. One moment! :books: ---------------------- If your GraphQL server does not support sort or where arguments and you're getting an error like "Unknown argument sort on field Query", you can override the dataProvider to remove these arguments from the query. Here's how you can do it according to a discussion on a Github issue (https://github.com/refinedev/refine/issues/2189):
import { graphql } from "@refine.dev";

export default graphql<{}>({
client: yourClient,
resources: {
posts: {
list: {
variables: (params) => {
const { sort, filter, ...rest } = params;
return rest;
},
},
},
},
});
import { graphql } from "@refine.dev";

export default graphql<{}>({
client: yourClient,
resources: {
posts: {
list: {
variables: (params) => {
const { sort, filter, ...rest } = params;
return rest;
},
},
},
},
});
In this example, the variables function in the list method of the posts resource is overridden to remove the sort and filter parameters from the query. This way, the query sent to the API will not contain sort and where options. For more information on how to override specific functions of data providers, you can refer to the Refine documentation (https://refine.dev/docs/faq/#how-i-can-override-specific-function-of-data-providers). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai how do I use this overriden data provider in my resource list?
K
kapa.ai83d ago
Let me check the knowledge base for you. One moment! :books: ---------------------- You can use the overridden data provider in your resource list by passing it to the Refine component's dataProvider prop. Here's how you can do it:
import { Refine } from "@refinedev/core";
import myDataProvider from "./myDataProvider"; // import your overridden data provider

const App = () => (
<Refine dataProvider={myDataProvider}>
{/* your resources */}
</Refine>
);
import { Refine } from "@refinedev/core";
import myDataProvider from "./myDataProvider"; // import your overridden data provider

const App = () => (
<Refine dataProvider={myDataProvider}>
{/* your resources */}
</Refine>
);
In this example, myDataProvider is the overridden data provider that you've created. It's passed to the Refine component's dataProvider prop, and it will be used for all data operations in your application. For more information on how to use data providers in Refine, you can refer to the Refine documentation (https://refine.dev/docs/data/data-provider#usage-1). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai the API I'm trying to consume data from returns a 400 http code, however, I can't figure out what is the message the api returns in order to debug my code

Let me check the knowledge base for you. One moment! :books: ---------------------- Refine expects errors to be extended from HttpError. When an API call fails, the error message from the API can be displayed by implementing error handling in your data provider. Here's a basic example of how to do this:
import { DataProvider, HttpError } from "@refinedev/core";

export const dataProvider = (apiUrl: string): DataProvider => ({
getOne: async ({ resource, id }) => {
try {
const response = await fetch(`<https://api.example.com/${resource}/${id}`>);

if (!response.ok) {
const error: HttpError = {
message: response.statusText,
statusCode: response.status,
};
return Promise.reject(error);
}

return {
data: response.data,
};
} catch (error) {
const error: HttpError = {
message: error?.message || "Something went wrong",
statusCode: error?.status || 500,
};
return Promise.reject(error);
}
},
// ...
});
import { DataProvider, HttpError } from "@refinedev/core";

export const dataProvider = (apiUrl: string): DataProvider => ({
getOne: async ({ resource, id }) => {
try {
const response = await fetch(`<https://api.example.com/${resource}/${id}`>);

if (!response.ok) {
const error: HttpError = {
message: response.statusText,
statusCode: response.status,
};
return Promise.reject(error);
}

return {
data: response.data,
};
} catch (error) {
const error: HttpError = {
message: error?.message || "Something went wrong",
statusCode: error?.status || 500,
};
return Promise.reject(error);
}
},
// ...
});
In this example, if the response from the API is not ok (i.e., the status code is not in the 200-299 range), an HttpError is created with the status text and status code from the response, and this error is rejected. You can also use an Axios interceptor to transform the error from the response before Axios returns the response to your code:
import axios from "axios";
import { DataProvider, HttpError } from "@refinedev/core";
import { stringify } from "query-string";

// Error handling with axios interceptors
const axiosInstance = axios.create();

axiosInstance.interceptors.response.use(
(response) => {
return response;
},
(error) => {
const customError: HttpError = {
...error,
message: error.response?.data?.message,
statusCode: error.response?.status,
};

return Promise.reject(customError);
},
);
export const dataProvider = (apiUrl: string): DataProvider => ({
// Methods
});
import axios from "axios";
import { DataProvider, HttpError } from "@refinedev/core";
import { stringify } from "query-string";

// Error handling with axios interceptors
const axiosInstance = axios.create();

axiosInstance.interceptors.response.use(
(response) => {
return response;
},
(error) => {
const customError: HttpError = {
...error,
message: error.response?.data?.message,
statusCode: error.response?.status,
};

return Promise.reject(customError);
},
);
export const dataProvider = (apiUrl: string): DataProvider => ({
// Methods
});
In this example, the Axios interceptor catches any error from the response and creates a custom HttpError with the message and status code from the error response. This custom error is then rejected.

@kapa.ai does the @refinedev/nestjs-query implement this error handling?
K
kapa.ai83d ago
Let me check the knowledge base for you. One moment! :books: ---------------------- The @refinedev/nestjs-query package is a data provider for APIs powered with Nest.js Query. However, the provided extracts do not specify whether this package implements the error handling as described in the previous examples. For more specific details on error handling with @refinedev/nestjs-query, you may need to refer to the package's documentation or source code. If the package does not handle errors as expected, you may need to extend or override its functionality to suit your needs. For more information on error handling in Refine, you can refer to the Refine documentation (https://refine.dev/docs/data/data-provider#error-format). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
