How can I limit the amount records that can be created
I would like to limit the total amount of records a user can create for a specific resource, I can retrieve this from the backend, but I wouldn't know how I would implement that to work in Refine

Hi @blackbearftw. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:

Hmm, I don't know enough to give you a confident answer yet. However, you might find it helpful to look into refine's data fetching hooks, such as
useCreateMany
, which is used to create multiple records. You could potentially use this hook in combination with some custom logic to limit the number of records a user can create.
You can find more information about these hooks in the refine documentation (https://refine.dev/docs/guides-concepts/data-fetching#fetching-data).

@kapa.ai well its more when a list is fetched, I could response along a canCreateRecord: true based on some logic in the backend
Let me check the knowledge base for you. One moment! :books:
----------------------
In that case, you can use the
useList
or useInfiniteList
hooks to fetch a list of records. When you fetch the list, you can include the canCreateRecord
field in your response from the backend.
Here's a basic example of how you might use the useList
hook:
In this example, data
would be the response from your API. You would replace the comments with your actual logic for handling whether or not the user can create a record.
You can find more information about these hooks in the refine documentation (https://refine.dev/docs/api-reference/core/hooks/data/useList/).

but doesn't this require a specific data structure for refine @kapa.ai ?

----------------------
Yes, refine does expect a specific data structure for the response from your API. For the
useList
and useInfiniteList
hooks, the response should include data
and total
fields. The data
field should be an array of records, and the total
field should be the total number of records.
However, you can include additional fields in your response as needed. In your case, you could include a canCreateRecord
field in your response. Refine will still be able to parse the data
and total
fields correctly, and you can access the canCreateRecord
field in your component.
Here's an example of how you might structure your response:
And here's how you might use this response in your component:
In this example, data
would be the response from your API. You would replace the comments with your actual logic for handling whether or not the user can create a record.
You can find more information about these hooks in the refine documentation (https://refine.dev/docs/api-reference/core/hooks/data/useList/).

what about useTable and getRowModel @kapa.ai
Let me check the knowledge base for you. One moment! :books:
----------------------
The
useTable
hook in refine is used to fetch data according to the sorter, filter, and pagination states. It uses the useList
hook under the hood for fetching the data. The getRowModel
method returned by the useTable
hook is used to retrieve the rows of the table.
Here's an example of how you might use these in your component:
In this example, rows
would be an array of row models for the table. Each row model represents a row in the table and provides methods for interacting with the row's cells.
If you want to limit the number of records a user can create, you could include a canCreateRecord
field in your response from the API, similar to the useList
example I provided earlier. You could then check this field before allowing the user to create a record.
You can find more information about the useTable
hook and the getRowModel
method in the refine documentation (https://refine.dev/docs/core/hooks/use-table/).

@kapa.ai can I show an error when the create action fails
Let me check the knowledge base for you. One moment! :books:
----------------------
Yes, you can show an error when the create action fails. Refine provides a way to customize the error notification that shows up when the data fetching fails. This can be done using the
errorNotification
prop in the useCreate
hook.
Here's an example of how you might use this:
In this example, mutate
is a function that you can call to create a new record. If the creation fails, the errorNotification
function will be called, and you can customize the error message that is shown.
You can find more information about this in the refine documentation (https://refine.dev/docs/core/hooks/data/use-create#errornotification).

@kapa.ai can I customize that message per error?
