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.
Please advice me, i have been looking at this for hours.
/Niklas.

Looks like you have Casting has_many :comments, and you have a comment form on your Casting show page. If so, then you just need to render your casting show page. But this requires you to supply the Casting show page the @casting variable in your controller. ... else @casting = Casting.find(@castingcomment.casting_id) render ''casting/show.html.erb'' end I would recommend that you not have a Castingcomment class. Say you need comments for different models, then you could have Anothermodelcomment class, etc. Consider having just a Comment model and create polymorphic associations from that model. Here''s a refernce http://www.arailsdemo.com/posts/20 Here is some background for that post http://www.arailsdemo.com/posts/16 -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
