Re: [Rails] Please advise on render:partial form.

[Garrett Lancaster]

In the create action, that typically ends up being `render :action => :new`

Call the render method (there are loads of ways you can call it. I'd expect this approach 
to be covered by almost any "write a something app in 5 minutes" type tutorial

Background:

On my application users can post Castings [class Casting] now i want
other users to be abel to post Comments on the Castings
[Castingcomment].

Approach:

views/castings/show.html.erb '

<%= render :partial => 'castingcomment_form' %>

app/controllers/castingcomments_controller.rb

def create
@castingcomment = Castingcomment.new( params[:castingcomment] )
if @castingcomment.save
redirect_to :controller => "castings", :action => "show", :id =>
@castingcomment.casting_id
else
# what to write here ?
end
end

The problem:

When the form validates it all works, but if create goes to a error
what to write there ? I need to render the same page (views/casting/
show.html.erb) again to show the error to the user.
