render_to_string in lib class not working

Question

I'm trying to use delayed_job to update a remote database via xml

In my lib folder I put a file with a class that should do a render_to_text with template.xml.builder, but I get:

undefined method `render_to_string' for #<SyncJob:0x7faf4e6c0480>... 

What am I doing wrong?

Answer 1

ac = ActionController::Base.new() ac.render_to_string(:partial => '/path/to/your/template', :locals => {:varable => somevarable}) 

Answer 2

I had problems with a undefined helper method then I used ApplicationController

ApplicationController.new.render_to_string
