Can't connect a model to anothe model on Prisma-CodePudding

I'm developing a simple project for food ordering and I'm using Node.js, Express, and Prisma as ORM for dealing with SQlite.

This is my actual schema.prisma:

generator client {
  provider = "prisma-client-js"
}

datasource db {
  provider = "sqlite"
  url      = env("DATABASE_URL")

The Controller will receive this JSON:

{
    "name": "Tomato sandwich",
    "description": "Tomato sandwich",
    "price": "22.00",
    "category": "Main",
    "ingredients": "09ea6c56-a289-474a-ac2a-33ccd7512c6e"
}

And on my repository I have a function for add a product on my database:

async create(name, description, price, category, ingredients) {
    return await prisma.products.create({
      data: {
        name,
        description,
        price,
        category,
        ingredients: {
          connect: { id: ingredients },
        },
      },
    });
  }

But I'm not able to create the relationship with the ingredients table, this error occurs:

The required connected records were not found. Expected 1 records to be connected after connect operation on one-to-many relation 'ProductsToProductsHasIngredients', found 
0.

CodePudding user response：

Basically the Ingredients table do not have the ingredient you wanted to to connect while creating the Product. You can do something like Create or Connect or only create instead of connect.

    ingredients: {
      connectOrCreate: {
        where: {
          id: ingredients,
        },
        create: {
          id: ingredients
          ...otherRequiredFields,
        },
      },
    },
