Question

Having this route:

map.foo 'foo/*path', :controller => 'foo', :action => 'index' 

I have the following results for the link_to call

link_to 'Foo', :controller => 'foo', :path => 'bar/baz' # <a href='/foo/bar%2Fbaz'>Foo</a> 

Calling url_for or foo_url directly, even with :escape => false, give me the same url:

foo_url(:path => 'bar/baz', :escape => false, :only_path => true) # /foo/bar%2Fbaz 

I want the resulting url to be: /foo/bar/baz

Is there a way around this without patching rails?

Answer 1

Instead of passing path a string, give it an array.

link_to 'Foo', :controller => 'foo', :path => %w(bar baz) # <a href='/foo/bar/baz'>Foo</a> 

If you didn’t have the route in your routes file, this same link_to would instead create this:

# <a href='/foo?path[]=bar&path[]=baz'>Foo</a> 

The only place I could find this documented is in this ticket.
