Rails - model association for recursive user model relationship

Question

In my user model, I have

  belongs_to :admin_creator, foreign_key: :created_by_user_id, class_name: "User"

and in my create controller action I have...

def create
    @user = User.new(user_create_params)
    @user.created_by_user_id = current_user.id
    @user.status_code = 'P' #set status code to pending

    begin
      @user.save!
      render json: "User #{@user.email} added", status: :created 
    rescue StandardError => e
      render json: @user.errors.full_messages, status: :unprocessable_entity 
    end

  end

How can I recast my code to to use model association for "current_user" who would be the admin_creator?

When create action is called, current_user is the current admin user who is adding another (child) user account. I'm thinking it would be along the lines of... @user = current_user.users.build(user_create_params) or similar

Answer 1

Add a has_many to the User model like this:

has_many :admin_children, foreign_key: :created_by_user_id, class_name: "User"

Then you can do:

current_user.admin_children.create(user_create_params)
