I have the following setup:
class NewsItem < ActiveRecord::Base
has_many :connections, :as => :connectable, :dependent => :destroy
has_many :ideas, :through => :connections
end
The relationship is a has_many :through that is also polymorphic.
I can add ideas to news items with this code:
@news_item.ideas.push(related_ideas)
related_ideas is an array of ideas.
The problem comes when I try to update the ideas for an existing news
item.
First I tried this:
@news_item.ideas.replace(new_ideas)
This literally does nothing - no log output at all, no DB activity.
Then I tried this:
@news_item.ideas.clear
@news_item.ideas.push(new_ideas)
Again, nothing at all. No error, nada. I would have expected the
‘clear’ method call to remove the records that associate the news
items and the ideas.
What am I doing wrong?
Thanks,
Hunter
