reactjs - React，Graphql CRUD 应用程序 - 删除突变删除列表中的第一个

Question

我正在尝试使用 Graphql 在 React 中创建一个简单的 CRUD 演示。

我有后端工作，我有创建和阅读。

我正在输出一个食谱名称列表，并有一个要添加到列表中的输入字段。

列表中的每个配方都有一个删除按钮来删除该配方。

我有删除工作，但不是删除配方点击它总是删除列表中的第一个配方。

正确的 id 被传递给 delete Mutation 但网络选项卡显示列表中第一个配方的 id。

谁能看到我做错了什么。

服务器端

schema.js

exports.typeDefs = `

  type Recipe{
    _id: ID
    name: String
    description: String
  }

  type Query{
    recipe:[Recipe]
  }

  type Mutation{
    addRecipe(name: String!, description: String):Recipe,
    deleteRecipe(_id: ID):Recipe
  }

`

解析器.js

exports.resolvers = {

  Query: {
    recipe: async (obj, args, { Recipe }, info) => {
      const allRecipes = await Recipe.find()
      return allRecipes
    }
  },
  Mutation: {
    addRecipe: async (obj, { name, description }, { Recipe }, info) => {
      const newRecipe = await new Recipe({
        name,
        description
      }).save()
      return newRecipe
    },
    deleteRecipe: async (obj, { id }, { Recipe }, info) => {
      const recipe = await Recipe.findOneAndRemove({ id })
      return recipe
    }
  }
}
