运行 graphQL 突变的正确方法是什么？

Question

我正在使用 Rails 中的 GraphQL 并发送一个突变以在 Graphiql 中创建一个用户。我得到的只是错误。

我正在以下文件中设置突变类型和逻辑。我将只显示我的 createUser 突变，因为那是我无法通过的突变。

create_user.rb

class Mutations::User::CreateUser < Mutations::BaseMutation
    argument :attributes, Types::UserInputType, required: true
    field :user, Types::UserType, null: false
    field :errors, [String], null: false

    def resolve(attributes:)
        user = User.new(attributes.to_kwargs)
        if user.save
            {
                user: user,
                errors: []
            }
        else
            {
                user: nil,
                errors: user.errors.full_messages
            }
        end
    end
end

module Types
  class UserType < Types::BaseObject
    field :id, ID, null: false
    field :fname, String, null: true
    field :lname, String, null: true
    field :email, String, null: true
    field :password, String, null: true
    field :dpsst, String, null: true
    field :reports, [Types::ReportType], null: true
    field :reports_count, Integer, null: true
    field :token, String, null: false

    def reports_count
      object.reports.size
    end

  end
end

user_input_type.rb

  description "Attributes to create a user."
  argument :fname, String,'Firstname of user', required: true
    argument :lname, String,'Lastname of user', required: true
    argument :email, String,'Email of user', required: true
    argument :password, String,'Password of user', required: true
    argument :passwordConfirmation, String, 'Password confirmation', required: true
    argument :dpsst, String,'dpsst number of user', required: false
end

mutation_type.rb

module Types
  class MutationType < Types::BaseObject
    # TODO: remove me
    # field :test_field, String, null: false,
    #   description: "An example field added by the generator"
    # def test_field
    #   "Hello World"
    # end
    field :create_user, mutation: Mutations::User::CreateUser

    field :login, mutation: Mutations::User::Login
    field :token_login, mutation: Mutations::User::TokenLogin
    field :logout, mutation: Mutations::User::Logout
    field :update_user, mutation: Mutations::User::UpdateUser
    field :reset_password, mutation: Mutations::User::ResetPassword
    field :send_reset_password_instructions, mutation: Mutations::User::SendResetPasswordInstructions
    field :unlock, mutation: Mutations::User::Unlock
    field :resend_unlock_instructions, mutation: Mutations::User::ResendUnlockInstructions
  end
end

下面是我在下面尝试过的几个突变布局。我只是不知道如何写他们100％！或者可能我的 graphiql 搞砸了，因为我正在插入应该根据互联网工作的突变。我怀疑它可能与 to_kwargs 方法有关......

突变：

mutation createUserMutation($userInput: CreateUserInput!){
  createUser(input: $userInput) {
    user {
      id
      fname
    }
  }
}
  "userInput": {
    "email":"test@gmail.com",
    "password": "password",
    "fname":"Jake",
    "lname":"Tester",
    "passwordConfirmation":"password",
    "dpsst":"75323",
  }
}

mutation createUserMutation($attributes: UserInput!){
  createUser(input: {attributes: $attributes}) {
    user {
      token
      id
      fname
      lname
    }
  }
}
{
  "attributes": {
    "email":"test@gmail.com",
    "password": "password",
    "fname":"Jake",
    "lname":"Tester",
    "passwordConfirmation":"password",
    "dpsst":"75323"
  }
}

在最近的尝试中，我收到以下错误：

{
  "error": {
    "message": "unknown attribute 'passwordConfirmation' for User.",
    "backtrace":...(I can post this if you need it)

请教我如何进行正确的突变调用，或者至少为我指明正确的方向。谢谢！

找到问题。

由于设计需要密码确认，但我的实际创建用户逻辑不需要它，我可以在使用信息创建用户之前删除该密钥。我修复了它：

create_user.rb

class Mutations::User::CreateUser < Mutations::BaseMutation
    argument :attributes, Types::UserInputType, required: true
    field :user, Types::UserType, null: false
    field :errors, [String], null: false

    def resolve(attributes:)
        userAttributes = attributes.to_kwargs
        if userAttributes[:password] == userAttributes[:passwordConfirmation]
            userAttributes.delete(:passwordConfirmation)
        end
        user = User.new(userAttributes)
        # userAttributes.attributes.except
        if user.save
            {
                user: user,
                errors: []
            }
        else
            {
                user: nil,
                errors: user.errors.full_messages
            }
        end
    end
end
