RoR Graphql Types::BaseObject NameError

Question

当向我的rails后端发出graphql API请求时，我在app/graphql/types/query_type.rb中得到以下错误:

Started POST "/graphql" for 127.0.0.1 at 2023-04-06 13:27:07 +0200
Processing by GraphqlController#execute as */*
Parameters: {...}
Completed 500 Internal Server Error in 266ms (ActiveRecord: 0.0ms | Allocations: 3660)

NameError (uninitialized constant Types::BaseObject):
app/graphql/types/query_type.rb:2:in `<module:Types>'
app/graphql/types/query_type.rb:1:in `<main>'
...

这是QueryType类:

module Types
class QueryType < Types::BaseObject
field :discord_user, DiscordUserType, null: true do
argument :id, ID, required: true
end
def discord_user(id:)
DiscordUser.find(id)
end
field :discord_users, [DiscordUserType], null: false
def discord_users
DiscordUser.all
end
end
end

我自己没有发现命名约定的错误，因为BaseObject是由graphqlgem提供的，我不知道为什么会有一个错误。

Answer 1

你好像嵌套错了。

module Types # Types here 
class QueryType < Types::BaseObject # Types
field :discord_user, DiscordUserType, null: true do
argument :id, ID, required: true
end
def discord_user(id:)
DiscordUser.find(id)
end
field :discord_users, [DiscordUserType], null: false
def discord_users
DiscordUser.all
end
end
end

试

module Types  
class QueryType < BaseObject 
field :discord_user, DiscordUserType, null: true do
argument :id, ID, required: true
end
def discord_user(id:)
DiscordUser.find(id)
end
field :discord_users, [DiscordUserType], null: false
def discord_users
DiscordUser.all
end
end
end

Answer 2

是否定义了BaseObject?中定义了BaseObject→应用程序/graphql/类型/base_object.rb

module Types
class BaseObject < GraphQL::Schema::Object
field_class Types::BaseField
end
end
