Hi Chris,
I've a simple example how you can do this:
Model:
require 'radius'
class Content < ActiveRecord::Base
def body
context = Radius::Context.new do |c|
c.define_tag 'render' do |tag|
content = "<!--partial-->[render]=" + tag.attr['partial'] +
"<!--partial-->"
end
end
parser = Radius::Parser.new(context, :tag_prefix => 'r')
return parser.parse('<p>hello <r:render
partial="partials/google_adsense" /></p>')
end
end
View:
<div class="body">
<% @content.body.split("<!--partial-->").each do |body| %>
<% if body.include?("[render]=") %>
<%= render :partial=>body.split("[render]=")[1] %>
<% else %>
<%= markdown(body) %>
<% end %>
<% end %>
</div>
Maybe i could help you
