Hi,

I’m using Rails 1.2.3 (constraint of the hosting company). I’m  
getting this error

Unknown action  
No action responded to subscriber

upon visiting [http://mydomain.com/super\_admin/subscriber/search](http://mydomain.com/super_admin/subscriber/search)

I have these files:

app/controllers/super\_admin\_controller.rb  
app/controllers/super\_admin/subscriber\_controller.rb  
app/views/super\_admin/subscriber/search.rhtml

and below is my routes.rb file. I had to comment out the  
“map.namespace :super\_admin do |adm|” because when I included it, I  
got an ‘Application error Rails application failed to start properly"’  
error.

As always, your help is greatly appreciated, - Dave

Just a hunch but you probably don’t have a method in your  
super\_admin\_controller.rb named subscriber. I see that second  
controller you wrote was app/controllers/super\_admin/  
subscriber\_controller.rb . You don’t really believe that, that url  
goes to that second controller do you?

wel it looks like rails is assuming that  
super\_admin/subscriber/search  
means super\_admin controller, subscriber action, id = search  
instead of super\_admin module, subscriber controller, search action,  
no id  
(which is fair enough - the 2 do have the same path)  
You could probably help rails by disambiguating the routes, ie stick a  
map statement that will explicity map that url to the right controller.

Thanks, Fred. I added this line

map.connect ‘/super\_admin/subscriber/search’, :controller =\>  
“super\_admin/subscriber”, :action =\> “search”

and it worked. But I have a follow up question. Do I have to add a  
line to routes.rb for each action in the subscriber controller? Is  
there a way I can write a single line to encompass all actions? Keep  
in mind I’m working with that older version of Rails, 1.2.3.

Best, - Dave

Oh, you do know that if you freeze the rails gems in to vendor you can  
run any version of rails you want, regardless of what gems the hosting  
company has installed ?

Thanks, the previous command worked. Also, on the freezing, I knew  
you could freeze backwards, but can you freeze forwards? If they’re  
running 1.2.3 and I have 2.0.2 on my dev environment, can I make that  
work?

The whole point of freezing is that instead of loading rails from gems  
you load it from /vendor.  
The host doesn’t even need to have rails installed, the version of  
their gems is completely irrelevant.
