将 schema.grahql 匹配到数据库表

Question

我有以下数据库表。 我创建了以下 schema.graphql 文件，但感觉我没有正确建模某些表和关系。 如何修复 schema.graqhql 以匹配数据库中的表？

type User @model {
  id: ID!
  username: String!
  postedRecipes: [Recipe] @connection(keyName: "byUser", fields: ["id"])
  purchasedRecipes: [Recipe] @connection(keyName: "byUser", fields: ["id"])
  buyTransactions: [Order] @connection(keyName: "byUser", fields: ["id"])
  sellTransactions: [Order] @connection(keyName: "byUser", fields: ["id"])
  cookingCoins: Int!
}

type Recipe @model @key(name: "byUser", fields: ["userID"]) {
  id: ID!
  title: String
  description: String
  price: Int
  author: User @connection(fields: ["userID"])
  purchasers: [User] @connection(fields: ["userID"])
}

type Order @model @key(name: "byRecipe", fields: ["recipeID"]) {
  id: ID!
  item: Recipe @connection(fields: ["recipeID"])
  price: Int
  seller: User @connection(fields: ["userID"])
  buyer: User @connection(fields: ["userID"])
}
