redirecto_to within helpers

rubyonrails-talk

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.
