Question

Hi Guys I have a Relationships in Mongoid and I can not add current_user to this relation for get the user that create the deal. A relation with 3 model.

I have three models user.rb, house.rb and deal.rb

user.rb Relationships (devise model)

# Relationships
has_many :houses, dependent: :destroy
has_many :deals, dependent: :destroy
key :title

house.rb

# Relationships
 belongs_to :user
 embeds_many :deals

deal.rb

# Relationships
 embedded_in :house, :inverse_of => :deals
 belongs_to :user

In my routes.rb

 resources :houses do
  resources :deals
 end

In my houses_controller.rb in my create method I get current_user for each house of this side:

def create
   #@house = House.new(params[:house])
   @house = current_user.houses.new(params[:house])
    respond_to do |format|
      if @house.save
        format.html { redirect_to @house, notice: 'House was successfully created.' }
        format.json { render json: @house, status: :created, location: @house }
      else
        format.html { render action: "new" }
        format.json { render json: @house.errors, status: :unprocessable_entity }
      end
    end
  end

In my deals_controller.rb I have the created method this:

    def create 
      @house = House.find_by_slug(params[:house_id])
      @user = User.find(:user_id)
      @deal = @house.deals.create!(params[:deal])
      redirect_to @house, :notice => "Comment created!" 
    end

How I can add to this last method create, the current_user that created the deal?

You can simply add these two lines to the create action:

@deal.user=current_user
@deal.save

And I would also suggest you not to use create! instead you should use .new and .save like in the scaffolded create actions! 😉
