Hey all
I'm experimenting with writing a scraper at the moment and have hit a

Part of the DOM is added after the page has loaded via javascript.
This means when I make an a request the HTML response I receive back
doesn't accurately represent the page.
Here's a simplified example:
doesn't send, it's likely an issue with your login details
or with the smtp domain.
Also, check that

Hi Valentino
You shouldn't use puts, for output in the view.
You probably want to split the info for each event into seperate cells
so your table is well-structured.
In which case I'd write a helper_method and throw most of the work
into there.
If not, you can stop html from collapsing

Sure,
From what you've written, it looks like your event model has
attributes called dreq_reqno, dreq_status and dreq_create_time and
you've joined these together with the event_detail method.
If this is the case, you could add a method in on of your helper files
(probably EventsHelper) that
:
Page.find_by_pageTitle(:pageTitle)
Also - I would try to stick to the convention of underscoring column
names rather than camelCase.

Vipin,
wouldn't it be better moving this out of the controller altogether?
If every A should have a B then I'd create an observer - AObserver
and add an after_create callback:
class AObserver ActiveRecord::Observer

B.create! :a_id = a.id
