Get current controller name/action name from view

Hi.

I swear I found this in the group archives, but now I cannot find this in the group or elsewhere online!

In a view I would like to get the current controller name and action that was used to get here.

For example, I have a template that I'm using from two different controllers (and four different actions in each controller), such as :controller => "my_view", :action => "current" (or "expired", or "fixed", etc.)

In this template I'm constructing some links to specific parameter calls of this same template, and I need to know which controller was used and what action was called to get us here. I thought it was something like this:

link_to "This Year", :controller => @controller.name, :action => @controller.action

The only thing I've found in the api that looks remotely similar is UrlHelper's current_page(), but that's not quite what I'm after, as I don't want to test something, I just WANT that something :slight_smile:

Thanks.

Here is a link to what I think you are looking for

Good luck.

In a view I would like to get the current controller name and action that was used to get here.

params[:controller] params[:action]

In this template I'm constructing some links to specific parameter calls of this same template, and I need to know which controller was used and what action was called to get us here. I thought it was something like this:

link_to "This Year", :controller => @controller.name, :action => @controller.action

Use url_for (or a named route), then _don't_ pass the controller in. Url_for will find the controller in params if you don't pass it in.

(Write tests for all this stuff, using assert_xpath, to detect you are getting the links you expect!)

Excellent, thanks!

I also just found this: http://snippets.dzone.com/posts/show/4391

<%= controller.controller_name %> <%= controller.action_name %>
