Link_to :back problem

Rails
1

Hello,

I have used <%= link_to “Back”, :back %> many times with no issues.
This time I am getting this error:

Unknown action
No action responded to index. Actions: access_denied, check_roles,
create, new, role_requirements, role_requirements=, and update

Any thoughts on this? I really need to use :back as the page I am
trying to go “back” to is part of a somewhat complex multipage form.
And I don’t want to resend a lot of info back to the form just to get
off of the tiny static “privacy policy” page.

Thanks for the help.

That error message seems to indicate that :back creates a link to the
index action of the controller. The message says that it can’t find an
index action and then lists the actions it did find.

My book says :back refers to the url in the HTTP_REFERER header in the
current request. Maybe :back isn’t finding any url, so link_to is
defaulting to :index?

I tested that out, and it seems that when you don’t specify an action
for link_to, the action defaults to the current action.
