<Edit> Save works, Delete doesn't

Hi! Confused about this one. I'm using <Edit> to populate a form with existing data. It prepopulates correctly, and any edits I make are stored. However, delete does not -- in fact, it doesn't make the API call at all. I have canDelete: true enabled in _app. Any advice?

Hi @avangeous. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- In the <Edit> component, the canDelete property allows you to add a delete button. If the resource has the canDelete property, refine adds the delete button by default. When clicked on, the delete button executes the useDelete method provided by the dataProvider. Here's an example of how you can use it:

import { Edit } from "@refinedev/antd";  // replace "antd" with your UI library
import { usePermissions } from "@refinedev/core";  

const PostEdit: React.FC = () => {  
 const { data: permissionsData } = usePermissions();  
 return (  
 <Edit  
 canDelete={permissionsData?.includes("admin")}  
 deleteButtonProps={{ size: "small" }}  
 saveButtonProps={{ size: "small" }}  
 >  
 <p>Rest of your page here</p>  
 </Edit>  
 );  
};

import { Edit } from "@refinedev/antd";  // replace "antd" with your UI library
import { usePermissions } from "@refinedev/core";  

const PostEdit: React.FC = () => {  
 const { data: permissionsData } = usePermissions();  
 return (  
 <Edit  
 canDelete={permissionsData?.includes("admin")}  
 deleteButtonProps={{ size: "small" }}  
 saveButtonProps={{ size: "small" }}  
 >  
 <p>Rest of your page here</p>  
 </Edit>  
 );  
};

In this example, the delete button is only shown if the user has "admin" permissions. You can adjust this according to your needs. If the delete button is present but the API call is not being made, it could be an issue with your dataProvider configuration. The dataProvider is responsible for making the actual API calls. You might want to check your dataProvider setup and ensure that the delete method is correctly implemented. For more information, you can refer to the following documentation: - <Edit> component (https://refine.dev/docs/api-reference/antd/components/basic-views/edit) - useDelete hook (https://refine.dev/docs/api-reference/core/hooks/data/useDelete/) - dataProvider (https://refine.dev/docs/api-reference/core/providers/data-provider/) - usePermissions hook (https://refine.dev/docs/api-reference/core/hooks/authentication/usePermissions/) ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai My dataprovider provides a deleteOne rather than useDelete. Could this be why?

kapa.ai•14mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- Yes, that could be the reason. The useDelete hook in refine uses the deleteOne method from your dataProvider to delete a record. If your dataProvider provides a deleteOne method, it should work correctly with the useDelete hook. Here's an example of how the deleteOne method might look in your dataProvider:

deleteOne: async ({ resource, id, variables }) => {  
 const url = `${apiUrl}/${resource}/${id}`;  
  
 const { data } = await axiosInstance.delete(url, {  
 data: variables,  
 });  
  
 return {  
 data,  
 };  
},

deleteOne: async ({ resource, id, variables }) => {  
 const url = `${apiUrl}/${resource}/${id}`;  
  
 const { data } = await axiosInstance.delete(url, {  
 data: variables,  
 });  
  
 return {  
 data,  
 };  
},

In this example, deleteOne is an asynchronous function that takes an object with resource, id, and variables properties. It constructs a URL using the resource and id, sends a DELETE request to that URL with axiosInstance.delete(), and then returns the response data. When you call useDelete, it returns a mutate function. You can then call this function with an object containing resource and id properties to delete a record:

const { mutate } = useDelete();  
  
mutate({  
 resource: "products",  
 id: 1,  
});

const { mutate } = useDelete();  
  
mutate({  
 resource: "products",  
 id: 1,  
});

In this example, mutate is called with an object containing resource and id properties. These properties are passed to the deleteOne method in your dataProvider. If your deleteOne method is correctly implemented and useDelete is still not working, there might be another issue. You might want to check the rest of your dataProvider configuration and your component code. For more information, you can refer to the following documentation: - useDelete hook (https://refine.dev/docs/api-reference/core/hooks/data/useDelete/) - dataProvider (https://refine.dev/docs/api-reference/core/providers/data-provider/) ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai deleteOne doesn't seem to be called. Any possible reasons?

kapa.ai•14mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- There could be several reasons why the deleteOne method is not being called: 1. Check your useDelete hook usage: Ensure that you're calling the useDelete hook correctly in your component. The useDelete hook returns a mutate function that you can call to delete a record. Here's an example:

    const { mutate: deleteBlogPost } = useDelete();

    const { mutate: deleteBlogPost } = useDelete();

You can then call deleteBlogPost with an object containing resource and id properties to delete a record:

    deleteBlogPost({ resource: "posts", id: 2 });

    deleteBlogPost({ resource: "posts", id: 2 });

Refer to the useDelete documentation (https://refine.dev/docs/api-reference/core/hooks/data/useDelete/) for more details. 2. Check your dataProvider configuration: The useDelete hook uses the deleteOne method from your dataProvider to delete a record. If deleteOne is not being called, there might be an issue with your dataProvider configuration. Ensure that you've correctly implemented the deleteOne method in your dataProvider. Here's an example:

    deleteOne: async ({ resource, id, variables }) => {  
     const url = `${apiUrl}/${resource}/${id}`;  
      
     const { data } = await axiosInstance.delete(url, {  
     data: variables,  
     });  
      
     return {  
     data,  
     };  
    },

    deleteOne: async ({ resource, id, variables }) => {  
     const url = `${apiUrl}/${resource}/${id}`;  
      
     const { data } = await axiosInstance.delete(url, {  
     data: variables,  
     });  
      
     return {  
     data,  
     };  
    },

Refer to the dataProvider documentation (https://refine.dev/docs/api-reference/core/providers/data-provider/) for more details. 3. Check your API endpoint: Ensure that the API endpoint you're trying to hit exists and is correctly configured to handle DELETE requests. The deleteOne method constructs a URL using the resource and id properties and sends a DELETE request to that URL. If you've checked all of these and deleteOne is still not being called, there might be another issue. You might want to check the rest of your dataProvider configuration and your component code. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai I don't actually have <edit> on /dispatches/:id; its in a drawer on my main /dispatches page. Could this be why?

kapa.ai•14mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- Yes, that could be the reason. The <Edit> component reads the id information from the route by default. If it's used on a custom page, modal, or drawer and cannot read the id from the URL, you need to use the recordItemId prop to provide the id information. Here's an example of how you can use it:

import { Edit } from "@refinedev/mui";  // replace "mui" with your UI library
  
const CustomPage: React.FC = () => {  
 return (  
 <Edit resource="posts" recordItemId={123}>  
 <span>Rest of your page here</span>  
 </Edit>  
 );  
};

import { Edit } from "@refinedev/mui";  // replace "mui" with your UI library
  
const CustomPage: React.FC = () => {  
 return (  
 <Edit resource="posts" recordItemId={123}>  
 <span>Rest of your page here</span>  
 </Edit>  
 );  
};

In this example, recordItemId is set to 123. You should replace 123 with the id of the record you want to edit. The <Edit> component needs the id information for the <RefreshButton> to work properly. For more information, you can refer to the following documentation: - <Edit> component (https://refine.dev/docs/api-reference/mui/components/basic-views/edit) ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai I already had recordItemId being passed; save works fine. It's just delete.

kapa.ai•14mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- If the recordItemId is being passed correctly and the save functionality works fine, but the delete functionality doesn't, it might be an issue with the DeleteButton component or the deleteOne method in your dataProvider. Here's how you can use the DeleteButton component:

import { DeleteButton } from "@refinedev/mui";  // replace "mui" with your UI library
  
const MyDeleteComponent = () => {  
 return <DeleteButton resource="posts" recordItemId="1" />;  
};

import { DeleteButton } from "@refinedev/mui";  // replace "mui" with your UI library
  
const MyDeleteComponent = () => {  
 return <DeleteButton resource="posts" recordItemId="1" />;  
};

In this example, DeleteButton is used with resource and recordItemId props. You should replace "posts" and "1" with your resource name and record id. When you click the DeleteButton, it triggers the useDelete method, which in turn calls the deleteOne method in your dataProvider. If the DeleteButton is present but the API call is not being made, it could be an issue with your dataProvider configuration. The dataProvider is responsible for making the actual API calls. You might want to check your dataProvider setup and ensure that the deleteOne method is correctly implemented. For more information, you can refer to the following documentation: - DeleteButton component (https://refine.dev/docs/api-reference/mui/components/buttons/delete-button) - useDelete hook (https://refine.dev/docs/api-reference/core/hooks/data/useDelete/) - dataProvider (https://refine.dev/docs/api-reference/core/providers/data-provider/) ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
