Redirecto_to within helpers

Rails
#1

Hi all,

In one of my helpers I would like to call a redirect_to(url) action. I
know the helpers are supposed almost only for formatting the view
purposes but it’s the best way I have found to do what I want. If I call
the redirect_to action in a helper I get the error:

undefined method `redirect_to’ for #<#Class:0x23aaedc:0x23aaeb4>

any solution for this?

Thanks,
Alvaro.

There are some hackish ways. Let’s start with the basics though:

What are you actually trying to do? Share that and someone can come up
with
the solution for you. If it’s a redirect, then it needs to be called
from a
controller. The best place to put that kinda stuff is the same place you
put
before_filters: in the controller itself as a protected method, or in
app/controllers/application.rb as a protected method if you want all
controllers to see it.

(protected doesn’t really make it protected in the Java sense, it just
makes it so it’s not a URL action, as all public methods in controllers
become actions, especially if you leave the default routes in).

Hi Brian,

yes I tried to call a redirect from within a helper, but after thinking
twice I recognise that is a bad idea so I have rewritten the code to
call it from the controller.

Thank you anyway for the response.

Alvaro.
