fetch user_profiles by avoiding N+1 query in graphql - ruby-on-rails

Question

I am using graphiql-ruby gem for using graphql. I am trying to get the list of users with its userprofile and its company. However, it consumes more than 5 minutes and hits the api several times. It even crashes my server. Can anyone help me at this, please?
this is what i have done
module Queries
module Users
extend ActiveSupport::Concern
include GraphQL::Schema::Member::GraphQLTypeNames
included do
field :users, [Types::UserType], null: false
field :user, Types::UserType, null: false do
argument :id, ID, required: true
end
field :currentUser, Types::UserType, null: false
end
# Get all users list except admins
def users
User.where.not(roles: ['admin'])
# context[:current_user].logs.info!('User Data Fetched') && user
end
def user(id:)
User.find(id)
end
def current_user
context[:current_user]
end
end
end
module Types
class UserType < Types::BaseObject
field :id, ID, null: false
field :email, String, null: false
field :user_profile, Types::UserProfileType, null: false
field :grants, [Types::GrantType], null: true
field :companies, [Types::CompanyType], null: true
field :my_companies_with_grants, [Types::CompanyGrantType], null: true
def grants
Grant.where(user_id: object.id)
end
def my_companies_with_grants
current_user = User.find_by(id: object.id)
company = current_user.companies
userid = current_user.id
company.map {|comp| { company: comp, grants: comp.get_user_grants(userid), company_id: comp.id } }
end
end
end
Here is how i am querying for the list of users
query {
employees: users {
id
email
userProfile {
...UserProfile
}
roles
createdAt
companies {
...Company
}
grants {
...Grant
}
}
}
${COMPANY}
${GRANT}
${USER_PROFILE}
why it is taking too long time to load all the users ? How can it be make efficient?
UPDATE
class ApiSchema < GraphQL::Schema
mutation(Types::MutationType)
query(Types::QueryType)
use GraphQL::Batch
end
Record loader
class RecordLoader < GraphQL::Batch::Loader
def initialize(model)
#model = model
end
def perform(ids)
#model.where(id: ids).each { |record| fulfill(record.id, record) }
ids.each { |id| fulfill(id, nil) unless fulfilled?(id) }
end
end
I changed my user_type.rb and did the following for user_profile
field :user_profile, [Types::UserProfileType, null: true], null: false do
argument :id, [ID], required: true
end
def user_profile(ids:)
RecordLoader.for(UserProfile).load_many(ids)
end
But i get "message":"Field 'userProfile' is missing required arguments: ids" issue
I setup the graphql-batch but could not figure out where should i use RecordLoader as per the way I am using(types and resolvers)
