Ajax with Radius Tag in Frontend

Ruby Apps Radiant CMS
1

Hi

I started with Radiant a few days ago and want to use Ajax in the
fronted.

I would like to do it as radius tag so that I can use functionality in
layouts and snippets. Everywhere I searched for possible solution I got
following article: AJAX Controller/View Methods/Helpers in Extension/Tag Block - Radiant CMS - Ruby-Forum

So I tried following:

The Tag module:

module CustomerReferencesTags
include Radiant::Taggable

tag ‘customerReferences:index’ do |tag|
link_to_remote ‘A’, :url =>{ :action => ‘ajaxtest’ }
end
end

The result of this try was "undefined method “link_to_remote’ for #”.

Does somebody know the current way to do it in Radiant or knows a good
turtorial?

Thx a lot for help.

You’re better off just writing the JavaScript code yourself. Radiant’s
tag definitions live in the model layer (essentially) and don’t have
access to the ActionView helpers. That said, you might be able to do
something like this:

tag ‘myAjaxTag’ do |tag|
helper = ActionView::Base.new
helper.send :instance_variable_set, “@request”,
tag.globals.page.request
helper.link_to_remote ‘A’, :url => {:action => ‘ajaxtest’, :controller
=> ‘mycontroller’ }
end

However, that’s a lot of work just to create a link with an Ajax
callback. It would be better practice to create a plain link and then
apply the Ajax callback unobtrusively. LowPro’s Remote.Link works well
for that. Something like this:

In your JS

Event.addBehavior({
‘a.remote’: Remote.Link
});

In your HTML
