Ruby on Rails: gem devise session logged in

Question

I have two tables, company and employee, so I would like when I register an employee, his registration was also for the company that was already logged, that is, without having to have to choose which company of that employee. How would I do this in ruby on rails? I'm using gem devise to login.

Answer 1

Try this in your User Controller:

    @user = User.new(user_params)
    @user.company_id = current_company.id
    respond_to do |format|
      if @user.save
        format.html { redirect_to @user, notice: 'User was successfully created.' }
        format.json { render :show, status: :created, location: @user }
      else
        format.html { render :new }
        format.json { render json: @user.errors, status: :unprocessable_entity }
      end
    end
  end

MODEL COMPANY:

class Company < ApplicationRecord
  # Include default devise modules. Others available are:
  # :confirmable, :lockable, :timeoutable, :trackable and :omniauthable
  devise :database_authenticatable,
         :recoverable, :rememberable, :validatable
    has_many :user
end

MODEL USER (the user is the employee):

class User < ApplicationRecord

  belongs_to :company

  enum kind: { pattern: 0, admin: 1 }

  has_many :approved

  has_many :expenses

end

COMPANY CONTROLLER:

      @companies = Company.all

      format.html
