Rails attributes not being saved -

when trying save new entity (vote) ajax calls, attributes not being assigned.

class , method being used:

class votecontroller < applicationcontroller     respond_to :json      def vote         question_id = params[:question][:id]         user_id = current_user.id         vote = vote.where(["question_id = :q", { q: question_id }]).where(["user_id = :u", { u: user_id }]).take         respond_with |format|             if vote.nil?                 @vote = vote.new                 @vote.question = question_id                 @vote.user = user_id                 @vote.save                 format.json { render :json => { :status => 'ok' } }             else                             format.json { render :json => { :status => 'failed', :msg => 'you voted' } }             end         end     end end 

the model:

class vote < activerecord::base     belongs_to :user     belongs_to :question      attr_accessor :user, :question end 

and migration:

class createvotes < activerecord::migration   def change     create_table :votes |t|         t.references :question         t.references :user     end   end end 

these parameters being sent:

parameters: {"utf8"=>"✓", "question"=>{"id"=>"1"}, "commit"=>"up vote"} 

with puts tested current_user.id indeed returns value.

and here query executed:

insert `votes` values () 

my records in database:

+----+-------------+---------+ | id | question_id | user_id | +----+-------------+---------+ |  1 |        null |    null | |  2 |        null |    null | |  3 |        null |    null | |  4 |        null |    null | |  5 |        null |    null | |  6 |        null |    null | |  7 |        null |    null | +----+-------------+---------+ 

why aren't these attributes being assigned?

because attr_accessor :user, :question "covering up" activerecord's methods of same name. remove line , try again.
