LENZ book -- limit users to 1 vote

[rornew]

anyone -- know how to limit the user to 1 vote.

I cannot believe this book did not include the code for this.

I'm assuming that the code belongs in the story controller...somewhere here:

def vote

@story = Story.find(params[:id])
@story.votes.create ( :user => @current_user)

I'm new...I googled everything, and have found nothing.

I'm assuming it would be an if /else statement...checking to see if the story has a user id that matches the current user id. If so, the vote should not be counted.

Any help would be great. It's a good book. But not including code like this makes this book incomplete.

You can (and should use validations [1]:

class Vote < ActiveRecord::Base
  validates_uniqueness_of :user_id, :scope => :story_id
end

You may need to change the names according to your database schema.

I will try this tonight and let you know the outcome.

Hopefully, this code can help other beginners.
