Question

Problem with using the REST-ful link_to while using it in a mailer.

Answer 1

+1 A:

Here's an example of a working template, I can't say for sure why yours isn't working but try generating the url in the notifier.

# notifier
def new_message_email(response)
    I18n.locale = response.recipient.language
    subject      I18n.t(:you_have_received_new_message_from_sender, :sender => response.sender.login)
    from         "[email protected]"
    recipients   response.recipient.email
    content_type "text/html"
    sent_on      Time.now
    body         :sender_login => response.sender.login, :recipient_login => response.recipient.login
  end

#template
= word_wrap "Hi #{@recipient_login}."
= word_wrap ""
%p
= word_wrap "You have received a new personal message from #{@sender_login}.", :line_width => 60
= word_wrap "Click #{link_to 'here', account_inbox_url} to view your domain.com message inbox.", :line_width => 60
= word_wrap "If the above URL does not work try copying and pasting it into your browser. If you continue to have problems, please feel free to contact us at [email protected].", :line_width => 60

You will need to generate a url, rather than a path.

eg:
account_path => /account
account_url => http://domain.com/account

edit: this should work:

#notifier
body         :unsubscribe_url => unsubscribe_url(:email => "[email protected]")

#template
= word_wrap "Click #{@unsubscribe_url} to unsubscribe.", :line_width => 60

(see above example for how this all fits together)

Answer 2

+1 A:

Does this unsubscribe_url (or _path) work in any other view?

The returned value looks like a something made from a Hash converted to String. Try to call .inspect on the object returned by "link_to()" - maybe there will be some clue?

Maybe something redefined a link_to method somewhere in your code? Use "grep def.*link_to" - maybe some clues will be there?

A test may be useful in this and later cases. Here is an example (however this is what I use in rails 1, but I hope this does not differ too much in your rails version).

def test_routing
  assert_routing '/unsubscribe', {:controller => 'user', :action => 'unsubscribe'}
  assert_recognizes Hash[:controller => 'user', :action => 'unsubscribe'],
      {:path=>'/unsubscribe', :method => :get},
      {"email"=>"[email protected]"}
  # ..and so on
end
