Link_to :back problem

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.

Anybody have any ideas on this one?

Thanks

error log?

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.
