Two issues after finishing the "Getting Started" guide

Hi!

I’ve just finished the “Getting Started” guide and I, although I have many questions (XD), I’m going to ask two:

  • I’ve noticed that when I update a “Post” record, the comments associated with the post disappear…does anyone have an idea of what can be happening?
  • I’ve tried to add some validation to the “Comments” model, but I just can’t find a way to display those errors in the “show post” page when submitting an invalidate comment :S
    If you want to check out the code I wrote, here it is: https://github.com/cinexin/MiniBlogRails

Greetings!
