The Mongo connector currently does not support Cascading Deletes

I'm working with Prisma and I want to support CASCADE delete but although I have done everything mentioned in the docs I'm still not getting it to work

this is the error I'm getting when I try to Prisma deploy

Errors:

  Restaurant
    ✖ The Mongo connector currently does not support Cascading Deletes, but the field `foods` defines cascade behavior. Please remove the onDelete argument.}

Here is the code

type Restaurant {
      id: ID! @id
      name: String!
      foods: [Food!]! @relation(onDelete: CASCADE, name: "FoodToRestaurant", link: INLINE)
    }

    type Food {
      id: ID! @id
      name: String!
      desc: String
      price: Float!
      category: Category!
      restaurant: Restaurant! @relation(name: "FoodToRestaurant", onDelete: SET_NULL)
    }

I expect when the restaurant gets deleted all its foods should also be deleted

I have CASCADE deleted with Prisma PostgreSQL but now I want to use MongoDB for this app

As it's not possible, you should manage it manually.

Means you should delete all of related entities recursively.

For example if it's your db schema:

Question -> Comment -> Rate

If you want to delete a question, you should delete all of comments related to that question, and if you want to delete a comment, you should delete all of rates assigned to that comment. So you need some recursive functions for deleting these entities.

function deleteQuestion(questionId) {
  for each comment related to questionID
    deleteComment(commentId)
  delete(questionId)       
}

function deleteComment(commentId) {
  for each rate related to commentId
    deleteRate(rateId)
  delete(commentId)       
}

function deleteRate(rateId) {
  delete(rateId)       
}
