Validates_presence_of fails on observer

Hi,

I have the following model that uses the plugin act_as_voteable:

class Video < ActiveRecord::Base

belongs_to :user

acts_as_voteable

acts_as_commentable

attr_accessible :url, :title, :description, :vote_count

validates_presence_of :url, :title, :description

end

I also have an observer for Vote model, so each time a user cast a vote to a video, or other content, I will update some info, including the vote_count on video model or other content. The code that runs each time a vote is created is:

def update_user_points_and_votes_count(vote, factor)

content_clazz = Kernel.const_get(vote.voteable_type)

content.vote_count +=1*factor

content.save!

end

Basically, I will update vote_count when a vote is casted to a video, or other kind of content that act_as_voteable.

The problem is that the instruction content.save! raises a validation exception on :url (in the list of validates_presence_of). I think that it will fail also on the other attributes in the list of validates_presence_of.

What I’m missing?

thank you,

Hi, I missed on line in the second block of code:

def update_user_points_and_votes_count(vote, factor)

content_clazz
= Kernel.const_get(vote.voteable_type)
#missing
content = content_clazz.fin(vode.voteable_id)

content.vote_count +=1*factor

content.save!

end

Thank you
