A gem for generating url-safe permalink-string from any other attribute in the same ActiveRecord model.
Make you urls look like
'/users/olkarls' instead of
put this in your gemfile:
And run in your terminal:
If your model doesn’t already have the permalink attribute you can run this generator command:
rails g has_permalink [Model]
That will generate a migration which adds a permalink attribute [Model] and indexes it. Don’t forget to:
class Post < ActiveRecord::Base has_permalink end
The plugin assumes that the permalink attribute is generated from the title attribute but it can be changed by providing an argument like this:
class Post < ActiveRecord::Base has_permalink :heading end
The permalink attribute is generated by the before_validation callback and is only transformed if it’s blank. If it's not blank and you want to regenerate it use:
Use this syntax your controller:
def show @post = Post.find_by_permalink(params[:id]) end
