Problem with url_for and named routes in ActionMailer View: "Controller and action required"

Question

I try to provide a confirmation link in my user welcome email and I get the following Rails error:

Need controller and action!

This bothers this line:

<p>Please take a moment to activate your account by going to: 
<%= link_to confirm_user_url(:id => @user.confirmation_code) %>.</p>

In my environment development.rb, I have the following line:

config.action_mailer.default_url_options = {
  :host => "localhost", :port => 3000
}

---

No problem with the variable @user. I tested email with things like @user.usernameand @user.confirmation_code. I'm having trouble with url_forand are called routes like confirm_user_url.

When I check my routes with rake routes, it appears confirm_user, so this is not a problem with the specified route that does not exist.

I can’t figure it out. What gives?
