I have never seen "if foo = 0" used to set a value for an optional argument in Ruby. It would either be "def bar(foo=0)" or "foo ||= 0". Can you give any example of what you're talking about?


My mistake. I didn't read parent carefully enough. Although it is common to see something like:

  if(@post = Post.find(params[:id]))
    render @post
  else
    render 'Post not found'
  end
