Passing information from an existing record, to a new record, of a different table

If I have Table A with columns title and description, and I want to create a record in Table B, which also has a title and description column, is there a way to pass that information to new_b_path such that the /views/b/_form.html.erb populates with the data from the A record?

I am using the below code to clone a workout but this is acting within Table A so to speak. I want to clone across tables. Any ideas?

workouts_controller.rb

...
  def new
    @workout_count = Workout.count
    if params[:cloned_workout]
        workout_to_clone = Workout.find params[:cloned_workout]
        @workout = workout_to_clone.clone
      else
    @workout = current_user.workouts.new 
  end
    respond_to do |format|
      format.html # new.html.erb
      format.xml  { render :xml => @workout }
    end
  end
...

/views/workouts/s开发者_StackOverflowhow.html.erb

<%= link_to "Clone Workout", new_workout_url + "?cloned_workout=#{@workout.id}", :class => "float-right" %>

Hmm. Judging by your explanation it sounds like a better strategy might be to simply create a table called Recommended with two belongs_to relationships that just has a workout_id and user_id column. Then you can associate the recommendation to a user and the workout. You could also have a gym_id or trainer_id column for the gym or trainer that made the recommendation. Make sense?
