Can you use controllers/views within a tag

Using radiant (mental), I have created my extension and have the
model/view/controller working from within the admin page layout with
no problems. I can create/list/edit/destroy my model instances.

Now, I want to list each instance of my model from within a page on
the website using a radius tag <r:mytag /> and the website layout. I
believe using a tag would be the most appropriate.

As I have tried so far, I have recreated the view from within my tag
using the content << “

” method. It seems that there
should be a better way so that I don’t repeat myself by creating two
views, one for the admin page and the second for the radius tag.

Is there a way to reuse the view/controller inside the radius tag?
Maybe something like

module MyTag
include Radiant::Taggable

desc %{ <r:mytag />

Displays the list of mytag available. }
tag “mytag” do |tag|
render(:controller => MyController, :action => MyAction)
end
end

or something to that effect.

I would also like to render the form so that users can input models on
my site as well. I just thought that I would try the list first.

Very new to all of this, so any pointers or directions would be much
appreciated.

Jason, can you clarify what you are trying to do a little more? You
seem to be asking multiple questions at once.

My question is…

Can a typical rails view (created under the extension in the
extension/app/view folder) be render from a radius tag?

Short answer: no. Long answer: maybe, but it could get ugly. Although
maybe what you’re trying to do doesn’t really need a traditional Rails
view template, but a collection of tags and a snippet? Let us know more
of what you want to do.

Displays the list of mytag available. }
tag “mytag” do |tag|
render(:controller => MyController, :action => MyAction)
end

I wish it was this easy.

I look forward to the discussion of how best to do this sort of thing…

Displays the list of mytag available. }
tag “mytag” do |tag|
render(:controller => MyController, :action => MyAction)
end

I wish it was this easy.

This is just off the top of my head but:

class EasyControllerExtension

def activate
class << SiteController
def show_uncached_page(url)
@page = find_page(url)
unless @page.nil?
@page.process_controller(self)
@cache.cache_response(url, response) if live? and @page.cache?
@performed_render = true
else
render :template => ‘site/not_found’, :status => 404
end
rescue Page::MissingRootPageError
redirect_to welcome_url
end
end
class << Page
attr_accessor :controller
def process_controller(controller)
@controller = controller
process(controller.request, controller.response)
end
end
end
end

Then you should be able to just do:

tag “mytag” do |tag|
tag.globals.page.controller.render(:partial => ‘monkeys’)
end

Jason, did you ever get this to work?

I tried to implement your suggestion here, but I was not successful.
I am not sure I follow what this code is doing…but I am still
learning ruby.

I attached my attempt. Maybe you or some else can see what is wrong.

This was the error I was getting

Oh, you need to explicitely require ‘application’ to load the
application controller - The application controller is not loaded until
after the extensions, which means that any reference to a controller
will be unable to load it’s superclass (as the class is named
ApplicationController, but it is loaded from an application.rb file - a
default I’ve never understood about rails, but I’m guessing it served a
historical purpose).

Unfortunately, I have pulled away from doing any more work on this,
but I hope to get back to this soon.
