Rails Validate String for URL "Safety"

Question

Let's say I have this route:

get 'post/:title' => 'post#show' , :as => 'show_post'

Anyone is able to create posts, and pick their own titles. I don't want the title to contain characters like '/', '[', ']' as it could lead to bad urls generated with the helper method show_post_path('blah'). I'm sure there are other things than those character I mentioned I should be looking out for.

I'm looking for a way to validate against this in the post model.

/ Thanks

You can use Rails parameterize method to validate the string Ex-

result = yourstring.parameterize

here is source http://apidock.com/rails/ActiveSupport/Inflector/parameterize
