ruby on rails - Why my data won't save to SQL? -

i'm quite new ruby on rails. i'll playing around it. actually, i'm trying create form title , daterangepick (bootstrap).

so, works fine until now. have 1 problem: data don't save in database. everytime submit form creates new record, inserts automatically "created_at" etc. 2 fields "title" , "date" empty every time... don't know fault is. may of can me? pls give me answer explication, cause i'm trying understand whats going on.

here code (i'm using simple_form gem)

new.html.erb:

<%= simple_form_for @event |f| %>     <%= f.input_field :title, required: false %>     <%= f.input :date, input_html: { class: "daterange" }, required: false %>     <%= f.button :submit %> <% end %> <script type="text/javascript">   $(document).ready(function() {     $('input[class="string optional daterange"]').daterangepicker(         {           locale: {             format: 'yyyy-mm-dd'           },           startdate: '2013-01-01',           enddate: '2013-12-31'         },         function(start, end, label) {           alert("a new date range chosen: " + start.format('yyyy-mm-dd') + ' ' + end.format('yyyy-mm-dd'));         });   }); </script> 

events_controller.rb:

class eventscontroller < applicationcontroller    def index     @event = event.all   end    def show    end    def new     @event = event.new   end    def create     @event = event.new(event_params)      if @event.save       redirect_to @event     else       render 'new'     end   end    private   def event_params     params.permit(:title, :date)    end end 

i think should enough... sure can post more of code if wish, think problem has here somewhere, since works fine... routes fines, can insert, redirects me /events/:id ... database keeps beeing empty. thank !!!

you need require in params:

  def event_params     params.require(:event).permit(:title, :date)   end
