Rails: Specifing params without value to link_to
activeresource, link-to-function, ruby-on-rails
Solution
If you don't add a value to the parameters you will not be respecting the W3C standard, which mandates that the params section has the form `field=value`.
I recommend that you add a new :most_popular action to your articles controller instead.
On your routes.rb:
map.resources :articles, :collection => {:most_popular=>:get}
On your controller:
class ArticlesController < ApplicationController
...
def most_popular
@articles = ...
end
On your views:
link_to most_popular_articles_path() # /articles/most_popular
This will be HTML-compliant, your urls will look practically the same (changing one ? by one /) and your controller will be simplified (you will have the most_popular action separated from the index).
Regards!
Update (2017): It appears that the W3C standard doesn't mandate the `field=value` syntax (or doesn't mandate it any more). However some servers are documented to "choke" on queries not complying with this syntax. See Is a url query parameter valid if it has no value? for details.
Problem
Supposing the route ``` map.resources :articles ``` how do you get this ``` /articles?most_popular ``` using `link_to` method? tried the following: ``` link_to articles_path(:most_popular) # exception link_to articles_path(:most_popular => nil) # /articles link_to articles_path(:most_popular => true) # /articles?most_popular=true ``` note: i'm using inherited_resources with `has_scope`
