Retrieve accurate data

Hi! Hope you're well! I have recipe categories (lasagne, chocolate cake...) that have recipes (vegetarian lasagne, gluten-free chocolate cake...). These recipes have ingredients (butter, eggs...) On the customer's side, I have a selector that allows the user to select the ingredients they want and don't want to have in their search. Example: the user wants recipes that have eggs AND apples, but NO cheese. A recipes with eggs, apples and butter must be displayed. Here's my query:

return await prisma.recipesCategory.findMany({
  where: {
    recipes: {
      some: {
        ingredients: {
          some: {
            ingredientId: { 
              in: ingredientsIdsWanted 
            },
      },
      every: {
        ingredientId: {
          notIn: ingredientsIdsNotWanted,
        },
      },
    },
      },
    },
  },
});

return await prisma.recipesCategory.findMany({
  where: {
    recipes: {
      some: {
        ingredients: {
          some: {
            ingredientId: { 
              in: ingredientsIdsWanted 
            },
      },
      every: {
        ingredientId: {
          notIn: ingredientsIdsNotWanted,
        },
      },
    },
      },
    },
  },
});

the problem I have with this query is that it returns the recipe even if it contains only one ingredient in the list, which is normal since there's the some However, if I put an every and the recipe contains additional ingredients, it won't be displayed even if the conditions are met. I've been trying to find a solution for I don't know how long, and I just can't seem to get it, I feel like I'm going crazy or maybe it's simple and I'm looking for too complicated ahah thanks in advance!

Hi @IceCrew Can you please share your schema? Meanwhile will this solve your usecase

return await prisma.recipesCategory.findMany({
  where: {
    recipes: {
      some: {
        AND: [
          {
            ingredients: {
              every: {
                ingredientId: {
                  in: ingredientsIdsWanted,
                },
              },
            },
          },
          {
            ingredients: {
              none: {
                ingredientId: {
                  in: ingredientsIdsNotWanted,
                },
              },
            },
          },
        ],
      },
    },
  },
  include: {
    recipes: {
      include: {
        ingredients: true,
      },
    },
  },
});

return await prisma.recipesCategory.findMany({
  where: {
    recipes: {
      some: {
        AND: [
          {
            ingredients: {
              every: {
                ingredientId: {
                  in: ingredientsIdsWanted,
                },
              },
            },
          },
          {
            ingredients: {
              none: {

This is my schema : https://github.com/lviardcretat/recepto/blob/main/prisma%2Fschema.prisma

GitHub

recepto/prisma/schema.prisma at main · lviardcretat/recepto

A solution for storing a large number of recipes and ingredients for daily use (recipe book, weekly recipe management, etc.). - lviardcretat/recepto

IceCrewOP•3mo ago

it doesn't work, that's the problem I was explaining above if I want to search for a recipe with just one of its ingredients, you won't find anything because with the every you have to put in ALL its ingredients
