Hello. I want create tag wich exec some method of controller and use its  
variables like views in rails. With templates and

example:

controllers/store\_controller.rb:  
class StoreController \< sitecontroller  
def find\_cart  
session[:cart] ||= Cart.new  
end

def add\_to\_cart  
@cart = find\_cart  
@cart.add\_product Product.find( params[:id] )  
end

def initialize  
@cart = find\_cart  
end  
end

modules/cart\_tags.rb:

tag ‘cart:show’ do |tag|  
t = StoreController.new  
@cart = t.cart  
ret = “”  
for cart\_item in @cart  
ret += cart.product+"  
"  
end  
ret  
end

You can not do that directly with standard Radiant, you need a Radiant  
\<-\> Rails integration extension.

Search this list for radiant+rails+integration, there have been a few  
post about this topic lately.

I for a long time use extension ‘rails\_support’. But I cannot use  
patterns created by radiant cms.  
For example it is necessary to add in tag the list from a method which  
it is stored in the controller.
