Juixe TechKnow knowing is half the battle

hey, lots of good stuff up here. sadly, I think the acts_as_voteable is broken. firstly the :submitted above should probably be :created_at as there is no submitted attribute in votes.

also the voted_for and voted_against methods use TRUE and FALSE which errors in mySQL since mySQL uses int(1) for boolean types. is there a reason for this? i hate to see good plugins fall out of service.

@Lawrence - Thanks for bringing this to my attention. On MySQL 4.1.15, the vote column is a tinyint(1) and I get no error casting votes. I guess I could just use 1/0 instead of TRUE/FALSE to cast a vote. Let me read up on booleans on MySQL…

Hey,

Thanks for this plugin. There is one thing though, I would like to go for the route of allowing a user to vote from 1 through 5, instead of a basic vote for 1 point for e.g (that’s what your plugin currently acts as).

How would I implement such a functionality? Could it be done with some slight modification to your plugin?

Hi, Thanks for the plugin, but for some reason it does not work for me. I have done what you have mentioned but it does not work and does not recognize the acts_as_voteable class or method.

Please tell me how i can fix this.

I’m using instantrails version 1.7

I had a 1 N database problem with using acts_as_voteable when applied to a list of comments. I solved this with some updated code. If you are including in the votes table correctly, this will yield 0 extra database hits and hopefully squeeze out some extra performance.

def votes_for
  votes_with_vote_of true
end

def votes_against
  votes_with_vote_of false
end

def votes_with_vote_of(vote)
  count = 0
  self.votes.each { |v|
    count  = 1 if v.vote == vote
  }
  count
end

I have no been able to get a validation working with act_as_voteable

How would I handle checking that the user_id, voteable_id, and vote are unique so the same person cant vote twice on the same post?

I’ve tried putting “validates_uniquness_of” everywhere but its not working. Under the Post.rb its not validating but the vote is still being entered in the db.

thanks

I had the same issue as Dan, but I solved it by creating a new instance method.

Just stick this under module InstanceMethods

def vote (value, user)
  if user
    self.votes.each { |v|
      if user.id == v.user_id
        if v.vote == value
          return false
        else
          v.update_attribute(:vote, value)
          return true
        end
      end
    }
    self.votes  value, :user_id => user.id)
    return true
  end
end

To use it just call rated_item.vote value, user for instance: ad.vote true, user

One quick caveat, you need to pass it actual boolean values or the comparison doesn’t work (at least with MySQL). So I have

vote_value = false
vote_value = true if params[:vote] == 'true'
ad.vote vote_value, user

in my controller. Hope this helps someone…

Is a reputation system planned (i.e. each vote can have a weight based on the user that expressed it)?

If not, any idea on how it should be implemented?

Keeping the reputation count in User can be expensive when retrieving the vote count for a voteable (each vote would have to be multiplied by the reputation every time), but storing the reputation in the vote it’s not right because it varies with time.

What do you think?

It’s been a while since you’ve made changes.. but I was wondering, is there a “neutral” vote?

I’ve added some functionality to this plugin, updated it to use named_scopes, the polymorphic keyword, and a couple other goodies.

I’m planning to add ranged voting (configurable as 1..10, etc) and karma-weighted voting as well.

Not sure if acts_as_voteable is still being maintained. If it is, I’m happy to fold my changes into the main project.

Otherwise, you can see my enhancements on GitHub, Vote Fu.

Hello, you have an error in the module acts_as_voteable.rb:

on line 12:

:dependent => :true

On rails 2.1.1 :dependent => :true raises a fatal error. You can change for :nullify with the same effects to correct this error.

Regards.

@Lukas: you just need to edit lib/acts_as_votable.rb under plugin directory. And change :dependent=>true to :dependent=>:destroy. it will work fine.
