How can I use raw queries with the graphql dataprovder library?

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:
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).

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):
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).

@kapa.ai how do I use this overriden data provider in my resource list?
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:
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).

@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:
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:
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.
For more information, you can refer to the Refine documentation (https://refine.dev/docs/data/data-provider#error-format).

@kapa.ai does the @refinedev/nestjs-query implement this error handling?
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).
