Thanks for your recipe! Exactly what I was looking for.

I have a very similar project running and I need to filter my projects for more than just one project.

Could anyone please post a hint how to get this working for filtering multiple Clients/projects (according to the example screenshot above). I tried to figure out on my own but I’m stuck.

Thanks in advance!

Yes, you append any list option as query string params to the URL, as you wrote in your comment.

Do I understand correctly that with this recipe, I can not have the search parameters in the URL without breaking my “clean” URL’s?

That is, if my code now generates these kinds of paths: controller/action/happy/2007

by going restful and using your recipe i will have to have this implementation: controller/action?term=happy&year=2007

Right?

@Steve: the list_option_names class method returns the names of all the named scopes you want to expose as list_options. You might have a named_scope that you use only internally. So in this case you would replace :named_scope_that_is_not_a_list_option with the name of the named_scope you don’t want to expose as a list option.

A scope becomes a list option when its name is returned from the list_option_names method. The method grabs the names of all defined scopes (self.scopes.map{|s| s.first} and removes the names of those you don’t want as list_options (- [ the list of scopes to be removed goes here ] ).

In my recipe, the :named_scope_that_is_not_a_list_option is a bogus name, representing whatever you might want to put in here.

Great article.

I am a little confused about what this is doing:

def self.list_option_names self.scopes.map{|s| s.first} - [:named_scope_that_is_not_a_list_option] end

specifically the
- [:named_scope_that_is_not_a_list_option]

How do scopes become “list options”? When I run this I get the same result with or without that line.
