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). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai well its more when a list is fetched, I could response along a canCreateRecord: true based on some logic in the backend
K

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:
import { useList } from "@pankod/refine";

const { data } = useList();

if (data?.canCreateRecord) {
// Allow the user to create a record
} else {
// Do not allow the user to create a record
}
import { useList } from "@pankod/refine";

const { data } = useList();

if (data?.canCreateRecord) {
// Allow the user to create a record
} else {
// Do not allow the user to create a record
}
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/). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

but doesn't this require a specific data structure for refine @kapa.ai ?
K
kapa.ai115d ago
Let me check the knowledge base for you. One moment! :books: ---------------------- 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:
{
"data": [
{
"id": 1,
"title": "Record 1"
},
{
"id": 2,
"title": "Record 2"
}
],
"total": 2,
"canCreateRecord": true
}
{
"data": [
{
"id": 1,
"title": "Record 1"
},
{
"id": 2,
"title": "Record 2"
}
],
"total": 2,
"canCreateRecord": true
}
And here's how you might use this response in your component:
import { useList } from "@pankod/refine";

const { data } = useList({ resource: "posts" });

if (data?.canCreateRecord) {
// Allow the user to create a record
} else {
// Do not allow the user to create a record
}
import { useList } from "@pankod/refine";

const { data } = useList({ resource: "posts" });

if (data?.canCreateRecord) {
// Allow the user to create a record
} else {
// Do not allow the user to create a record
}
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/). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

what about useTable and getRowModel @kapa.ai
K
kapa.ai115d ago
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:
import { useTable } from "@refinedev/react-table";

const {
getRowModel,
refineCore: {
tableQueryResult: { data: tableData },
},
} = useTable({
resource: "posts",
});

const rows = getRowModel().rows;
import { useTable } from "@refinedev/react-table";

const {
getRowModel,
refineCore: {
tableQueryResult: { data: tableData },
},
} = useTable({
resource: "posts",
});

const rows = getRowModel().rows;
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/). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai can I show an error when the create action fails
K
kapa.ai115d ago
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:
import { useCreate } from "@pankod/refine";

const { mutate } = useCreate();

mutate({
errorNotification: (data, values, resource) => {
return {
message: `Something went wrong when creating ${data.id}`,
description: "Error",
type: "error",
};
},
});
import { useCreate } from "@pankod/refine";

const { mutate } = useCreate();

mutate({
errorNotification: (data, values, resource) => {
return {
message: `Something went wrong when creating ${data.id}`,
description: "Error",
type: "error",
};
},
});
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). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

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

Let me check the knowledge base for you. One moment! :books: @blackbearftw That's a great question, but unfortunately I am only capable of responding to a maximum of five questions per thread. Don't hesitate to create a new thread for any further questions you have though. I'm here to help!

Hello @blackbearftw while you can do it with refine, it's not gonna be a reliable to enforce it on the client-side only. Ideally, your API should enforce that and return some error if user still tries to create something.
