Issue with passing parameter to action using link_to

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))

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?

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.

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).

If it were being directed to some other action, then ***************
should
not have been printed. And when I am trying to access this parameter
from
the view “index.html.haml”, its value is printed exactly what is being
passed.

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.

Verified it. Don’t have puts anywhere else.

Jim asked you to post the contents of the log (log/development.log)
when you click the link. Why have you not done that? Or have I
missed that message?

I haven’t posted the log yet because the code I posted is an example of
what I am using. I can’t post the code as it is proprietary. And so the
log
contains info that might violate it.

Create a new rails app and try to replicate the behavior. If you can do
that, we
might be able to help. If not, consult within your company. Good luck!

Thanks for the help. Will give it a try and post accordingly.
