Question

hello i was wondering if it was possible to retrieve the :id (the primary key that auto-increments in the db) after it gets saved? i have in my favorite_relationships controller

def create
    @lesson = Lesson.find(params[:favorite_relationship][:lesson_id])
    current_user.favorite!(@lesson)
    #params[:id] = ...
    respond_to do |format|
      format.html { redirect_to @lesson }
      format.js
    end
end

when current_user.favorite! gets called, it goes to my user model

  def favorite!(lesson)
    favorite_relationships.create!(lesson_id: lesson.id)
  end

however, is there a way to retrieve the :id the favorite_relationship is getting saved as? i wanted to set it in the commented out line

#params[:id] = 

i need to specify a params[:id] for a gem im using

thanks

I assume you are looking for favorite_relationships.id? in this case modify you controller to strore the value in the variable as

favorite_relationships = current_user.favorite!(@lesson)
params[:id]= favorite_relationships.id
