Howdy, the title mostly asks the question.
Given the following:
class Article < ActiveRecord::Base ; has_many :comments ; end class Comment < ActiveRecord::Base ; belongs_to :article ; end
I have an article already instantiated in the database, referenced as @article.
Will the following code always "create" (save to DB) a new comment?
@article.comments << Comment.new :text => "Blah blah..."
I would like to be able to add comments to an article that already already exists (and may already have comments that exist) in the database w/out the new comment being saved to the database.
I would try this: @article.comments.build :text => "Blan blah..."
The reason I don't is because my Comment class is sub-classed using STI. Thus, my code really looks more like this:
klass = Comment.get_class(params[:comment_type]) # get_class returns Comment or a sub-type @article.comments << klass.new :text => "Blah blah..."
Anyone have any ideas on how I can add STI comments to an article w/ out saving them, doing so "the right way" (I'm sure I could ugly-hack it)?
Thanks.
