Question

I am currently developing a blogging system with Ruby on Rails and want the user to define his \"permalinks\" for static pages or blog posts, meaning:

Answer 1

You should have seolink or permalink attribute in pages' or posts' objects. Then you'd just use to_param method for your post or page model that would return that attribute.

to_param method is used in *_path methods when you pass them an object.

So if your post has title "foo bar" and seolink "baz-quux", you define a to_param method in model like this:

def to_param
  seolink
end

Then when you do something like post_path(@post) you'll get the /posts/baz-quux or any other relevant url that you have configured in config/routes.rb file (my example applies to resourceful urls). In the show action of your controller you'll just have to find_by_seolink instead of find[_by_id].
