Question

Oddly enough, my model passes validation just fine, and acts as expected, however I still have the error rendered to the view.

# Controller
def up
  @vote = Vote.create :vote => true, :voter => current_user, :voteable => Recipe.find(params[:id])
  respond_to do |format|
    format.js { render :json => {:model => 'vote', :success => @vote.valid?, :errors => @vote.errors }}
  end
  @vote.errors.clear # <= doesn't seem to help
end

The model I wrote has a custom validation:

class Vote < ActiveRecord::Base

  # ... associations etc.

  validate :voter_voting_too_frequently?

  private

  def voter_voting_too_frequently?
    last_vote_cast_by_voter = Vote.find_last_by_voter_id self.voter
    unless last_vote_cast_by_voter.nil? || last_vote_cast_by_voter.created_at < 5.seconds.ago
      errors.add_to_base("You can only vote every 5 seconds.")
    end
  end
end

And lastly, the response that is rendered to the view: (returned as js no doubt, but would be the same if it were in a <div>)

{"errors":[["base","You can only vote every 5 seconds."]],"model":"vote","success":false}

And even though it was successful, this is continuously returned.

Ideas on how to debug this?

Answer 1

It doesn’t look like it is passing the validation since the success status is false.

If you take a look at you custom validation it seems that the “unless” keyword has caused some confusion.

Try:

if !last_vote_cast_by_voter.nil? && last_vote_cast_by_voter.created_at < 5.seconds.ago
  errors.add_to_base ...
