i have installed 'strong_parameters'. , trying make out it. can 1 please guide me model , controller code same.

remove attr_accessible models.

and in controller, lets take example of postscontroller, create private method post_params define accessible attributes of post model

class postscontroller < applicationcontroller      def update         @post = post.find(params[:id])         if @post.update(post_params)             redirect_to @post, notice: 'post updated.'         else             render "edit"         end     end      private      def post_params         params.require(:post).permit(:user_id, :description, :title)     end  end
