delete entity

I have an entity called File which has an id. Give me an example action to delete a File

Hi @cmilazzo. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- Sure, to delete an entity in Wasp, you can use the delete operation. Here is an example of how you can delete a File entity based on its id:

action deleteFile {
  fn: import { deleteFile } from "@src/actions.js"
}

action deleteFile {
  fn: import { deleteFile } from "@src/actions.js"
}

Then, in your actions.js file, you can implement the deleteFile function like this:

export const deleteFile = async (args, context) => {
  await context.entities.File.delete({ where: { id: args.id } })
}

export const deleteFile = async (args, context) => {
  await context.entities.File.delete({ where: { id: args.id } })
}

In this code, args.id is the id of the File entity you want to delete. The context.entities.File.delete function is provided by Wasp and it uses the Prisma's CRUD API under the hood. Please note that this is a basic example and does not include any error handling or validation. You might want to add those in a real-world application. For more information, you can refer to the Wasp documentation (https://wasp-lang.dev/docs/data-model/crud#declaring-a-crud-with-default-options). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ---------------------- Sorry @cmilazzo, I seem to be having a bit of trouble. Don't worry though, I've pinged my support and they will try to fix me up! :technologist: Perhaps try again in 15mins?

@kapa.ai Can you redefine the deleteFile function using typescript?

Let me check the knowledge base for you. One moment! :books: ---------------------- Sure, you can define the deleteFile function using TypeScript. Here's how you can do it:

import { PrismaClient } from "@prisma/client"

const prisma = new PrismaClient()

export const deleteFile = async (args: { id: number }, context: { entities: { File: typeof prisma.file } }): Promise<void> => {
  await context.entities.File.delete({ where: { id: args.id } })
}

import { PrismaClient } from "@prisma/client"

const prisma = new PrismaClient()

export const deleteFile = async (args: { id: number }, context: { entities: { File: typeof prisma.file } }): Promise<void> => {
  await context.entities.File.delete({ where: { id: args.id } })
}

In this code, args.id is the id of the File entity you want to delete. The context.entities.File.delete function is provided by Wasp and it uses the Prisma's CRUD API under the hood. Please note that this is a basic example and does not include any error handling or validation. You might want to add those in a real-world application.

@kapa.ai I get this error with that code: server/operations/actions/index.ts(87,7): error TS2353: Object literal may only specify known properties, and 'User' does not exist in type '{ File: FileDelegate<RejectOnNotFound | RejectPerOperation, DefaultArgs>; }'.

Wohooo @cmilazzo, you just became a Waspeteer level 6!

---------------------- The error message you're seeing suggests that the User entity is not recognized in the context of your deleteFile function. This could be because the User entity is not imported or not included in the context. If you're trying to access the User entity in your deleteFile function, you should ensure that it's included in the context. However, based on the function you've shared, it seems like you're only working with the File entity. Here's how your TypeScript function should look if you're only working with the File entity:

import { PrismaClient } from "@prisma/client"

const prisma = new PrismaClient()

export const deleteFile = async (args: { id: number }, context: { entities: { File: typeof prisma.file } }): Promise<void> => {
  await context.entities.File.delete({ where: { id: args.id } })
}

import { PrismaClient } from "@prisma/client"

const prisma = new PrismaClient()

export const deleteFile = async (args: { id: number }, context: { entities: { File: typeof prisma.file } }): Promise<void> => {
  await context.entities.File.delete({ where: { id: args.id } })
}

If you need to work with the User entity as well, you should include it in the context like this:

import { PrismaClient } from "@prisma/client"

const prisma = new PrismaClient()

export const deleteFile = async (args: { id: number }, context: { entities: { File: typeof prisma.file, User: typeof prisma.user } }): Promise<void> => {
  // Your implementation here
}

import { PrismaClient } from "@prisma/client"

const prisma = new PrismaClient()

export const deleteFile = async (args: { id: number }, context: { entities: { File: typeof prisma.file, User: typeof prisma.user } }): Promise<void> => {
  // Your implementation here
}

Please ensure that your User and File entities are correctly defined in your Wasp code. For more information, you can refer to the Wasp documentation (https://wasp-lang.dev/docs/data-model/crud#declaring-a-crud-with-default-options). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ---------------------- Sorry @cmilazzo, I seem to be having a bit of trouble.
