What's the proper way to run a graphQL mutation? - ruby-on-rails

Question

I'm working with GraphQL in rails and sending a mutation to create a User in Graphiql. I'm getting nothing but errors though.
I'm setting up the mutation types and logic in the following files. I'll just show my createUser mutation since that's the one I can't get past.
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
Now Here's a couple of the mutation layouts I've tried below. I just don't know how to write them 100%! or potentially my graphiql is messed up, because I'm inserting mutations that should work according to the internet. I suspect it might have something to do with the to_kwargs method...
mutations:
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"
}
}
With the most recent try, I'm receiving these errors:
{
"error": {
"message": "unknown attribute 'passwordConfirmation' for User.",
"backtrace":...(I can post this if you need it)
Please teach me how to make the proper mutation calls, or at least point me in the right direction. Thank you!

Answer 1

found the issue.
Due to devise needing the password confirmation, but my actual create user logic not needing it, I could delete that key before using the information to create a user. I fixed it with:
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
