You're right but you may have the same kind of puts code in other parts of your file.  We're just making
sure that it really is going to the index action.  Try to use debugger instead of puts when you're debugging.
There may be times when you're rendering the same template from a different action which is why
the value is printed correctly.

Hi,

I have a controller named Users with index action.

def index
    puts "************* #{params[:city]}"
    ...
    ...
end

From the view,
link_to(:city, list_users_with_city_path(:city => city.name))

You implied below that list_users_with_city_path is not yet defined
at this point so why is it not giving any errors?  where did you 
get list_user_with_city_path if you haven't defined it in the routed yet?

Wrote this by mistake. I use it this way after defining the path. What doesn't works is,

link_to(:city, users(:city => city.name)
And this is not giving any errors but nothing is received in the index action.

use users_path.  I'm not sure why it's not giving any errors.

Ah! Again I typed wrong. Yes, this is what I used, users_path and seems like I also missed the closing bracket for link_to up here. Certainly, it gave errors without "path".

So, with the correct syntax, link_to(:city, users_path(:city => city.name)), it didn't work.

i'm not sure why params[:city] isn't set when you reach that puts statement.  It may be caused by
a number of things.  Can you check if it really goes to the index action, you may have declared
something on your routes that takes precedence over the users resources?  Paste in the log after
you click on the link and you routes file (everything before the resources :users line).
 

 

 
 
But when I click on this link, it doesn't prints out anything for the params. All the "*" are being printed. The url in the browser displays,

localhost:3000/users?city=delhi

Instead when I create a new route, get '/users/:city' => 'users#index', :as => list_users_with_city
This works fine. I get proper output. 

What could be the problem?
