How do I destroy all the posts when the board is destroyed?

I got a application like following.

A board has many posts
All posts belong to a board

I try to destroy all the posts under a board when I destroy the board.
My destroy function is following.

  def destroy
    @board = Board.find(params[:id])
    @post = @board.posts
    @post.destroy
    @board.destroy

    respond_to do |format|
      format.html { redirect_to(boards_url) }
      format.xml { head :ok }
    end
  end

However, it does not work.
Could anyone tell me how to destroy all the posts when the board is
destroyed?

My source code is following.

Take a look at the :dependent option for associations:

class`` Board ``< ActiveRecord::Base

``has_many ``:posts``, ``:dependent => ``:destroy

end

  1. posts.each do |post|

post.destroy

end

  1. posts.delete_all

Hi I got a solution. Here is my destroy function. Many thanks for the
reply.

  def destroy
    @board = Board.find(params[:id])
    @board.posts.destroy_all
    @board.destroy

    respond_to do |format|
      format.html { redirect_to(boards_url) }
      format.xml { head :ok }
    end
  end

You are quoting my post, where I give you a solution that handles
everything with less coding effort in the model, where it belongs... But
fiddling around with a hack in the controller, that simply shouldnt do
such work.

But maybe I am the one who is wrong?
