show example of delete server action using prisma db client

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

#

Based on the information provided in the extracts, here's an example of how you can create a delete server action using Prisma DB client:

First, you need to create an API route that handles the delete request. This route retrieves the id of the record from the URL and uses Prisma Client to delete this record in the database.

// DELETE /api/post/:id
export default async function handle(req, res) { 
  const postId = req.query.id; 
  if (req.method === 'DELETE') { 
    const post = await prisma.post.delete({ where: { id: postId }, }); 
    res.json(post); 
  } else { 
    throw new Error(`The HTTP ${req.method} method is not supported at this route.`); 
  }
}

(Source: Vercel Guides (https://vercel.com/guides/nextjs-prisma-postgres))

Then, you can create a function in your component that calls this API route when the delete button is clicked:

async function deletePost(id: string): Promise<void> { 
  await fetch(`/api/post/${id}`, { method: 'DELETE', }); 
  Router.push('/'); // Redirect to home page after deletion
}

(Source: Vercel Guides (https://vercel.com/guides/nextjs-prisma-postgres))

Finally, you can use this function in your DropdownMenuItem for deletion:

<DropdownMenuItem onClick={() => deletePost(entry.id)}>Delete</DropdownMenuItem>

Please note that you need to replace post with the name of your model in the Prisma schema, and /api/post/${id} with the correct API route for your application.

Also, remember to import the necessary dependencies at the top of your file:

import { useRouter } from 'next/router'
import { PrismaClient } from '@prisma/client'

The useRouter hook is used to redirect the user after the deletion, and PrismaClient is used to interact with your database.

Please ensure to handle errors and edge cases appropriately in your application.

@agile aurora what options do ih ave besides router.refresh() or revalidate to update server page.

agile auroraBOT Jan 25, 2024, 11:45 AM

#

Let me check the knowledge base for you. One moment! :books:

#

Based on the information provided in the extracts, there are two main methods to manually refresh a route in Next.js:

router.refresh(): This method, provided by the useRouter hook, clears the Router Cache and makes a new request to the server for the current route. It does not affect the Data or Full Route Cache. The rendered result will be reconciled on the client while preserving React state and browser state. Source (https://nextjs.org/docs/app/building-your-application/caching#routerrefresh)
revalidatePath: This method allows you to manually revalidate data and re-render the route segments below a specific path in a single operation. Calling the revalidatePath method revalidates the Data Cache, which in turn invalidates the Full Route Cache. This method can be used in Route Handlers to revalidate data in response to a third party event (e.g. webhook) or in Server Actions to revalidate data after a user interaction (e.g. form submission, clicking a button). Source (https://nextjs.org/docs/app/building-your-application/caching#revalidatepath)

If you need to invalidate the whole client-side cache after a user signs out, you can use a workaround made by @clerkinc. However, the code for this workaround is not provided in the extracts. Source (https://github.com/vercel/next.js/issues/47812)

Please note that the effectiveness of these methods can depend on the caching strategy used on the server side. If the server is caching the data, then calling router.refresh() or revalidatePath might still return the same result. Source (https://github.com/vercel/next.js/issues/48157)

#

If you're looking for more granular control over your caching, you might want to look into using `app`, which allows revalidating tags/paths without page level ISR. Source (https://github.com/vercel/next.js/issues/48771)

@agile aurora if i can call the revalidatePath from different routes so its dynamic how would i do it then after a server action?

agile auroraBOT Jan 25, 2024, 11:49 AM

#

Let me check the knowledge base for you. One moment! :books:

#

To call revalidatePath dynamically after a server action, you would need to call it within the server action function, passing the path you want to revalidate as an argument. Here's a general example:

import { revalidatePath } from 'next/server';

export async function serverAction(req, res) {
  // Perform your server action here (e.g., database update)

  // Determine the path you want to revalidate
  const pathToRevalidate = `/your-path-here`;

  // Call revalidatePath with the determined path
  revalidatePath(pathToRevalidate);

  // Send response
  res.status(200).json({ message: 'Server action completed and path revalidated.' });
}

In this example, pathToRevalidate should be the path you want to revalidate. This can be determined dynamically based on the result of your server action.

Please note that revalidatePath only invalidates the cache when the path is next visited. This means calling revalidatePath with a dynamic route segment will not immediately trigger many revalidations at once. The invalidation only happens when the path is next visited. Source (https://nextjs.org/docs/app/api-reference/functions/revalidatePath)

Also, remember to handle errors and edge cases appropriately in your application.

@agile aurora what if the path to revalidate is dynamic and the action can be called from diff paths

agile auroraBOT Jan 25, 2024, 11:53 AM

#

Let me check the knowledge base for you. One moment! :books:

#

If the path to revalidate is dynamic and the server action can be called from different paths, you can pass the path as a parameter to your server action. Here's a general example:

import { revalidatePath } from 'next/server';

export async function serverAction(req, res) {
  // Extract the path from the request body or parameters
  const pathToRevalidate = req.body.path || req.query.path;

  // Perform your server action here (e.g., database update)

  // Call revalidatePath with the extracted path
  revalidatePath(pathToRevalidate);

  // Send response
  res.status(200).json({ message: 'Server action completed and path revalidated.' });
}

In this example, pathToRevalidate is extracted from the request body or parameters. This means you need to include the path in your request when calling the server action.

Please note that revalidatePath only invalidates the cache when the path is next visited. This means calling revalidatePath with a dynamic route segment will not immediately trigger many revalidations at once. The invalidation only happens when the path is next visited.
