[英]Graphql mutation error: "Field 'createUser' is missing required arguments: input"
I'm trying to follow along this article on how to create a mutation on a rails server using GraphQl https://www.howtographql.com/graphql-ruby/4-authentication我正在尝试遵循这篇关于如何使用 GraphQl https://www.howtographql.com/graphql-ruby/4-authentication在 Rails 服务器上创建突变的文章
However, I'm stuck at the CreateUser Mutation step, I get the follow error hash when trying it out in GraphiQL:但是,我被困在 CreateUser Mutation 步骤中,在 GraphiQL 中尝试时出现以下错误哈希:

I just followed the code in the article, my files:我只是按照文章中的代码,我的文件:
create_user.rb创建用户.rb
module Mutations
class CreateUser < BaseMutation
# often we will need input types for specific mutation
# in those cases we can define those input types in the mutation class itself
class AuthProviderSignupData < Types::BaseInputObject
argument :credentials, Types::AuthProviderCredentialsInput, required: false
end
argument :username, String, required: true
argument :auth_provider, AuthProviderSignupData, required: false
type Types::UserType
def resolve(username: nil, auth_provider: nil)
User.create!(
username: username,
email: auth_provider&.[](:credentials)&.[](:email),
password: auth_provider&.[](:credentials)&.[](:password)
)
end
end
end
user_type.rb用户类型.rb
module Types
class UserType < BaseObject
field :id, ID, null: false
field :email, String, null: false
field :username, String, null: false
field :photo, String, null: true
field :phone, String, null: false
field :island, IslandType, null: false, method: :island
field :archipel, ArchipelType, null: false, method: :archipel
field :created_at, String, null: false
field :updated_at, String, null: false
end
end
I have no clue where this 'input' thing is coming from.我不知道这个“输入”的东西是从哪里来的。
Without realizing I inilialized my project with a configuration that used Relay.没有意识到我使用使用 Relay 的配置初始化了我的项目。
By commenting this code inside my **_schema.rb file it worked again.通过在我的 **_schema.rb 文件中注释此代码,它再次起作用。
# Opt in to the new runtime (default in future graphql-ruby versions)
# use GraphQL::Execution::Interpreter
# use GraphQL::Analysis::AST
# Add built-in connections for pagination
# use GraphQL::Pagination::Connections
As well as these lines inside base_mutation.rb and replaces with these.以及 base_mutation.rb 中的这些行并替换为这些行。
# class BaseMutation < GraphQL::Schema::RelayClassicMutation
# argument_class Types::BaseArgument
# field_class Types::BaseField
# input_object_class Types::BaseInputObject
# object_class Types::BaseObject
# end
class BaseMutation < GraphQL::Schema::Mutation
null false
end
If you're not interested in commenting out fields... I ran across the same error.如果您对注释字段不感兴趣......我遇到了同样的错误。 For whatever reason
input
is the name of the key you pass your arguments into as a hash/object.无论出于何种原因,
input
都是您将参数作为散列/对象传递给的键的名称。
Example from using this tutorial: https://www.howtographql.com/graphql-ruby/3-mutations/使用本教程的示例: https : //www.howtographql.com/graphql-ruby/3-mutations/
mutation {
createLink(input: {
url: "foo",
description:"bar"
}) {
url
description
}
}
