Hi there,
I have a question on what would be the best way to save a HABTM model.
A posting habtm categories, and a category habtm postings.
class Category < ActiveRecord::Base
has_and_belongs_to_many :postings
end
class Posting < ActiveRecord::Base
has_and_belongs_to_many :categories
end
In my blog_controller, where the actual posting is saved, is where I
think I’m having some trouble. Here’s what I currently have to save a
post:
def create
@posting = Posting.new(params[:posting])
body_content = @posting.body
body_content.gsub!( /(.*)(\n)/, ‘\1
’ )
@posting.body = body_content
@posting.save!
@posting.user_id = session[:user_id]
logger.debug("Saving the post.")
if @posting.save
flash[:notice] = 'Posting was successfully created.'
redirect_to :controller => 'list', :action => 'index'
else
render :action => 'new'
end
end
I can successfully load all the categories into a multiple selection
box on the page that is creating the posting, but I’m unsure how to
save the posting.id and the category.id into the categories_postings
table within the ‘create’ action.
Thank you,
Dave H.
