Hi,
I have an app with nested resources - categories and services, so my
routes.rb contains the following
map.resources :categories do |category|
category.resources :services do |service|
end
Obviously this gives me urls like /categories/1/services/2
I would like to modify the app to display more human urls like
/categories/category_name/services/service_name
Or even better - /category_name/service_name
Both models have a name field in their database table.
Can anybody advise if there is a simple way to modify the routes.rb
and show actions in the controllers to set this up?
I feel like there must be a way to do this with minimal code and no
heavy lifting, but just can''t see it.
Thanks,
Dan

The to_param method on your model is what gets called to generate the
ID for the URL.
So a simple solution is to just change that. Lets say your "Category"
model has a unique "slug" field. You could change it to this:
class Category
def to_param
self.slug
end
end
Then instead of finding by ID in your controller like this:
Category.find(params[:id])
You would need to find by slug:
Category.find_by_slug(params[:id])
That doesn''t require any changes to routes. I know there are gems that
do this (maybe a little more elegantly). But this is a quick way to
get it working with minimal changes, and without any extra gems. Just
make sure whatever field(s) you use for to_param are unique.

Just an update on this thread. I now have pretty and meaningul urls of the form mysite.com/categories/ permalink However, there are evidently some old links out there on the web that still point at mysite.com/categories/1 These now throw an error. Is there any way to catch any urls that still contain an integer id and redirect them to the new permalink in the controller?

Hi,
I am confused as to how I would modify the routes to only catch the
urls that have an integer id?
For example, I have an articles resource so my routes file contains:
map.resources :articles
And I have modified my model file with
def to_param
permalink
end
and the controller to contain
@article = Article.find_by_permalink(params[:id])
Therefore, the working url would look like mysite.com/articles/
permalink
But every time someone tries to access mysite.com/articles/1 which was
posted as a link on a forum somewhere months ago I get an error
notification.
How would I modify the routes to stop this erroring and automatically
redirect to the appropriate permalink url?
Cheers Dan

Hi Marnen,> Either use a regex to match the parameter (and then send it to a > different controller action) or have a single controller action that > runs both find_by_permalink and find_by_id.I have added this to the controller which seems to work well, as my regex writing is weak. @article = Article.find_by_permalink(params[:id]) unless @article @article = Article.find(params[:id]) end Thanks for the help. I really appreciate it.

You don''t need a very sophisticated regex, and no Ruby programmer can afford to be scared of regexes. http://www.rubular.com is your friend if you need help. Regexes are an essential tool in anything involving string processing -- and that includes Rails routing. Don''t ignore them.> > @article = Article.find_by_permalink(params[:id]) > unless @article > @article = Article.find(params[:id]) > endThat works, but you might want to move it to the model (perhaps in a find_by_permalink_or_id method).> > Thanks for the help.

Setup an "old_article" route in routes.rb that explicitly matches those old urls... Something like (for 2.x): map.old_article ''/articles/:id'', ..., :requirements => {:id => /\d+-.*/} Then, in the action for old_article you can find the article and *301* redirect it to the new article URL. Doing this will get you a little SEO boost from Google. Or rather... they won''t punish you for duplicate content... If you''re using Rails 3, the syntax will change a bit and you could probably put it all in the routes file using the new redirect stuff. Maybe.
