Question

I have a user table and an organization table. When you sign up for a user, the application also creates a new organization for you. I did this by putting this code in user.rb:

class User < ActiveRecord::Base
  before_create :create_organization
  belongs_to :organization

  private
  def create_organization
    self.organization = Organization.create :name => self.name
  end
end

But there will be some cases where parameters will be passed on through the URL, such as

http://localhost:3000/sign_up?organization_id=10

How do I create some sort of if-then statement so that if the organization_id parameter is present, the user model DOESN’T create a new organization.. But instead submits the existing organization_id parameter as the organization_id for the user?

Answer 1

Simple add check into your model,

  def create_organization
    organization = Organization.create :name => name unless organization_id.present?
  end

And in your controller simply set organization_id from params.
