ruby on rails - My forum is not updating the table? -

-

i trying update table using fourm :-

<div class="row">    <div class="col-md-6 col-md-offset-3">     <%= form_for message.new |f| %>       <%= f.label :to %>       <%= f.email_field :to, class: 'form-control' %>          <%= f.label :subject %>       <%= f.text_field :subject, class: 'form-control' %>         <%= f.label :content %>       <%= f.text_area :content, class: 'form-control' %>         <%= f.submit "log in", class: "btn btn-primary" %>      <% end %>   </div> </div>

and in controller have done :-

  def create     @message = message.new(user_params)     redirect_to root_url    end      def user_params       params.require(:message).permit(:to, :subject, :content)      end

but when check table, there no update .

where going wrong ? table have 2 more attributes , not filling them forum .

.new builds new object, need save persist database.

def create   @message = message.new(user_params)   @message.save!   redirect_to root_url end
