[...] Acts As Rateable – If you have locations you’ll need to rate them right? Chances are there’s other things on your site that need rating as well, so this cleans up some of the code for this. It’s something that could be done without a plugin, sure, but adding “acts_as_rateable” to a model is all you need to get going. [...]

Ok just thought I’d let you know I fixed the issue by replacing the line 12 in acts_as_rateable.rb to:

has_many :ratings, :as => :rateable, :dependent => :destroy

The :dependent => true option on has_many association was deprecated in 1.1:

Hi, I’m getting the following error when trying to use this plugin with a model in rails 2.0.1:

ArgumentError in MediaController#articles

The :dependent option expects either :destroy, :delete_all, or :nullify (true)

My model is Article, it is currently using the following plugins:
has_self_referential_many_to_many :related
acts_as_taggable
acts_as_commentable
acts_as_rateable

If I comment out the first four plugins and leave rateable in, I still get the error. It’s currently breaking on this line:

Library/Ruby/Gems/1.8/gems/activerecord-2.0.1/lib/active_record/associations.rb:1149:in `configure_dependency_for_has_many’

Can you help?

with the newer version of rails there will be an error called :
“The :dependent option expects either :destroy, :delete_all, or :nullify (true)”
which appears in:
“vendor/plugins/acts_as_rateable/lib/acts_as_rateable.rb:12:in `acts_as_rateable’”

The Line looks like this :
“has_many :ratings, :as => :rateable, :dependent => true”

just change the true to one of these :
” :destroy This destroys the associated objects”

” :delete_all deletes them directly from the database ”

” :nullify to set the keys to null”

so the line should look somthing like this afterwards :

“has_many :ratings, :as => :rateable, :dependent => :destroy”

Anand:
The performance of the average rating calculation can be improved greatly by using SQL instead of ruby.

# Helper method that returns the average rating
#
def rating
  Rating.average( :rating, :conditions => {
    :rateable_id => self.id,
    :rateable_type => self.class.name
  })
end

Seth:
use the find_ratings_by_user method
