Question

I have a User model, which :has_many :widgets

Here is the ‘edit’ method:

  def edit
    @user = current_user
    @user.widgets.build   
  end

I have an edit view which contains a user form and a widget form nested within it

In my UserController#update method, I save the data…all working as designed.

After save, I want to send the user to Widget#show with the ID of the widget that was just added to User.widgets

How do I get that ID?

Here is my update method:

 def update
    @user = User.find(params[:user][:id], :include => [:widgets])
    if @user.update_attributes(params[:user])
       redirect_to widget_path(????), notice: 'Your new Widget is ready' }
    end
  end

Answer 1

Couldn’t you scope the @user.widgets.last.id request so that you are assured of getting their last widget, something like: @user.widgets.created_by(@user).last.id
