Hello all. This is a rails 3 oriented question.
I'm creating a simple, application-wide view-helper method in my
app/helpers/application_helper.rb that will be called in the context of
several different controller/action views.
module ApplicationHelper
def my_custom_link_to
link_to "Here Silly"
end
end
As you can see, by NOT providing any link-location (url_for) options, my
little helper will default to simply creating links to the current page
(uses the current controller and action to generate the link). This is
exactly what I want...
Except (I'm sure you saw this coming): I want the generated link to always
be identical (except for query string parameters) to the current URL as
shown in the browser's window. Normally, this is already the case for
default resource-routed links. However, I've got some resources available
through several (aliased?) routes. Example (config/routes.rb):
...
resources :entities
resources :rolodex, :controller => :entities
...
When I'm using my helper in my app/views/entities/index.html.erb, the path
in the generated link is always /entities, regardless of whether the page
was accessed through the /rolodex or /entities route. I'd like the path to
be /rolodex when the page is requested using this path and /entities when
/entities is requested. And just FYI, changing the fact that my "entity"
resource is available via these multiple routes isn't an option (and this
isn't the only resource we have with such aliasing).
The technique that (seems) to work the way I want it, it to change my method
above to use request.fullpath:
def my_custom_link_to
link_to "Here Silly", request.fullpath
end
Though this works, I'm wondering if there is a more idiomatic way to
accomplish this. So, is there?
Thanks!
