Hi @Joe Gaffney. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:
----------------------
The
useCustom
hook in Refine is designed to send custom query requests and it uses the custom
method as the query function from the dataProvider
which is passed to <Refine>
. It expects the url
and method
properties, which will be passed to the custom
method from the dataProvider
as parameters. When properties are changed, the useCustom
hook will trigger a new request.
However, useCustom
is a hook and hooks in React can't be called directly or conditionally, they must be used at the top level of a React function component or within a custom hook.
If you need to call a function directly, you might need to create a custom function that uses the custom
method from the dataProvider
directly, outside of a hook. This would involve interacting with your dataProvider
directly, which might require a deeper understanding of how your dataProvider
is set up.
Here's an example of how useCustom
is used:
In this example, useCustom
is used to send a GET request to the posts-unique-check
endpoint of the API. The url
and method
properties are passed to the custom
method from the dataProvider
as parameters.
For more information, you can refer to the useCustom documentation (https://refine.dev/docs/data/hooks/use-custom).

@kapa.ai But how would i call this function directly not from the hook is there a way to get the function call from the hook but not call it so i can call it later
Let me check the knowledge base for you. One moment! :books:
----------------------
In React, hooks are designed to be used directly in the component or inside other hooks. They cannot be called or stored for later use outside of these contexts. This is due to the way hooks maintain and manage state and side effects within the React component lifecycle.
If you need to perform an asynchronous operation based on an event (like a button click or a form submission), you could consider using a callback function or an event handler inside your component. This function can then use the hook and perform the necessary operations.
However, if you need to call a function directly and not from a hook, you might need to interact with your data provider directly. This would involve using the
custom
method from your data provider, which is what the useCustom
hook uses under the hood. This would require a deeper understanding of your data provider and how it's set up.
Unfortunately, without more specific information about your data provider and your use case, it's difficult to provide a more detailed answer. I would recommend checking the documentation for your specific data provider for more information on how to use it directly.

@kapa.ai how can i call the custom method on the data provider without using the hook
Let me check the knowledge base for you. One moment! :books:
----------------------
To call the
custom
method on the data provider directly without using the useCustom
hook, you would need to interact with your data provider directly. This would involve creating an instance of your data provider and then calling the custom
method on that instance.
Here's a general example of how you might do this:
In this example, dataProvider
is imported from @refinedev/simple-rest
, which is one of the data providers supported by Refine. An instance of the data provider is created with dataProvider("API_URL")
, and then the custom
method is called on that instance.
Please replace "API_URL"
, "your_custom_url"
, and "your_http_method"
with your actual API URL, the custom URL, and the HTTP method you want to use, respectively.
Remember that this is a general example and the actual implementation might vary depending on the specifics of your data provider and your use case. Always refer to the documentation of your specific data provider for more accurate information.
