ID + Slug name in URL in Rails (like in StackOverflow)

Question

I\'m trying to achieve URLs like this in Rails:

http://localhost/posts/1234/post-slug-name

with both ID and slug name instead of either

Answer 1

Use friendly_id. It has one nice feature: you can update your url without breaking the old one.

Generating view url isn't working for me. I just added a small method in the model

def to_param
  self.friendly_id
end
