Hi,
rails 3.2.8
I must be missing something basic (and it''s been driving me mad)
because I
am trying to send one additional data attribute to my controller from a
link, but I can''t seem to get it into the params received by the
controller.
I have looked around and found answers, but none seem to affect my links.
I''ve set up a dummy app with a home page and a single link to a
contacts
page - here is the code:
routes.rb
root :to => ''home#index'', :as =>
''home''
resource ''contacts''
Haml Home Page View
# I want to be able to display ''bar'' on the contacts page
= link_to "Contacts", contacts_path, :data => {:foo =>
''bar''}
The generated html link:
<a href="/contacts <http://localhost:3000/contacts>"
data-foo="bar">contacts
</a>
But I don''t receive the foo attribute in the params object in the show
action of ContactsController.
If I add {:method => :post} to link_to, then it routes to the create action
of the ContactsController but again, foo is missing.
= link_to "Contacts", contacts_path, {:method => :post, :data =>
{:foo =>
''bar''}}
generates:
<a href="/contacts <http://localhost:3000/contacts>"
data-foo="bar"
data-method="post" rel="nofollow">contacts</a>
Can anyone point me in the right direction?
Thanks
Paul

Hi Norbert, Thanks for the reply, but can you elaborate a little?

AFAIK the generated HTML link is correct data-foo=''bar'', shouldn''t this be accessible in the controller as part of the params hash? If I inspect the params hash, all that is there is the usual key/value pairs: controller, action, (when applicable => id, method, authenticity_token). How can I send an additional data attribute to the controller? Do I have problem with my routes?

It should show you the parameters being passed. Also if you do params.inspect what do you see? You can put that in a view or use a debugger.
