设置ruby-graphql：找不到用户类型

Question

I'm trying to make graphql-ruby working on my rails app. So far I got everything set up more or less, but when I go to the /graphiql page in my browser, I don't have access to my custom UserType (the predefined test case worked before, though. I'm getting this error message in the network tab of the developer tools: NoMethodError in GraphqlController#execute undefined method `UserType' for # GraphQL::Define::TypeDefiner:0x007fa3728b2348

Can you help me?

My schema is defined as following: (leaves_messenger_schema.rb)

LeavesMessengerSchema = GraphQL::Schema.define do
  mutation(Types::MutationType)
  query(Types::QueryType)
end

My UserType is defined as follows: (types/user_type.rb)

Types::QueryType = GraphQL::ObjectType.define do
  name "Query"

  field :viewer, types.UserType do
    resolve ->(obj, args, ctx) {
      ctx[User.last]
    }
  end
end

and my UserType (types/user_type.rb):

Types::UserType = GraphQL::ObjectType.define do
  name 'User'
  description 'A user'

  field :id, types.String
  field :email, types.String
end

my routes.rb is defined as per generator. That should be correct since I can navigate to the graphiql page and the test case worked.

Thanks a lot for any advice you can give me!

Answer 1

i think you made a typo, try to change your code from this

field :viewer, types.UserType do to field :viewer, Types::UserType do
