I have in routes.rb

map.resources :labs, :collection =\> { :group =\> :get }

which is working. But when I try to pass a parameter, e.g.

\<% form\_tag group\_labs\_path( :patient\_id =\> @patient.id ), :method  
=\> :get do %\>

The :patient\_id isn’t getting passed to the controller:

— !map:HashWithIndifferentAccess  
group: !map:HashWithIndifferentAccess  
id: “5”  
commit: Add Lab  
action: group  
controller: labs

Doing it the non-restful way works:

\<% form\_tag :action =\> :group, :patient\_id =\> @patient.id, :method  
=\> :get do %\>

— !map:HashWithIndifferentAccess  
group: !map:HashWithIndifferentAccess  
id: “6”  
commit: Add Lab  
method: get  
authenticity\_token: …  
action: group  
patient\_id: “8”  
controller: labs

Any idea how to configure the route to pass the parameter?

Many TIA,  
Craig

Have you tried just making a hidden field for the patient id? Since  
you’re submitting a form as a GET request, it should post all form  
data in the URL.

That’s an interesting design thought, which I’ll play with. But it  
seems to me I should still be able to configure the route in a RESTful  
way. Any idea how?

BTW

\<% form\_tag group\_labs\_path, :method =\> :get do %\>  
\<%= hidden\_field\_tag :patient\_id, @patient.id %\>

works perfectly of course 🙂 (Thanks!)

But I still don’t understand why

\<% form\_tag group\_labs\_path( :patient\_id =\> @patient.id ), :method  
=\> :get do %\>

isn’t permitted syntax. Someday I’ll understand RESTful routes, but  
not today 🙂
