Hello, I create a form with simple_form. Now I got 2 problems: 1)The validation fails, fx when a field is filled, the validation says the field is empty and the field is not marked red. Here is the controller: def new @action = Action.new @note_type [['Ad','Ad'],['Promotion','Promotion'],['Poll','Poll'],['Location','Location']] end def create @note_type [['Ad','Ad'],['Promotion','Promotion'],['Poll','Poll'],['Location','Location']] @action = Action.new(params[:action_params]) if @action.save flash[:success] = "New Action saved" redirect_to "/" else render 'new' end end private def action_params params.require(:action).permit(:action_name, :startDate,:endDate,:contentURL, :previewImageURL,:message,:noteType, :prob,:maxSendingsDayAll,:maxSendingsTotalAll, :maxSendingsDeviceAll,:maxSendingsDeviceTotal, :updateInterval) end action.rb(model): class Action < ActiveRecord::Base VALID_URL_REGEX = /\A[\w+\-.]+@[a-z\d\-.]+\.[a-z]+\z/i before_save { self.contentURL = contentURL.downcase } before_save { self.previewImageURL = previewImageURL.downcase } validates :action_name, presence: true validates :startDate, presence: true validates :endDate, presence: true validates :contentURL, presence: true, format: { with: VALID_URL_REGEX } validates :previewImageURL, presence: true, format: { with: VALID_URL_REGEX } validates :message, presence: true validates :noteType, presence: true validates :prob, presence: true validates :maxSendingsDayAll, presence: true validates :maxSendingsTotalAll, presence: true validates :maxSendingsDeviceAll, presence: true validates :maxSendingsDeviceTotal, presence: true validates :updateInterval, presence: true end new.html.erb <h1>New Action</h1> <div class="row"> <div class="span6 offset4"> <%= simple_form_for(@action) do |f|%> <%= render 'shared/error_messages' %> <%=f.label :action_name, "Action name"%> <%=f.text_field :action_name%></br> <%=f.input :startDate,:as => :datetime_picker, :label =>"Start date"%> <%=f.input :endDate,:as => :datetime_picker, :label =>"End date"%> <%=f.label :contentURL, "Content url"%> <%=f.text_field :contentURL%></br> <%=f.label :previewImageURL, "Preview image url"%> <%=f.text_field :previewImageURL%></br> <%=f.label :message, "Message"%> <%=f.text_area :message%></br> <%=f.label :noteType, "Note type"%> <%=f.select(:noteType, @note_type,:html =>("multiple"))%></br></br> <%=f.label :prob, "Sending probhability"%> <%=f.number_field :prob%></br> <%=f.label :maxSendingsDayAll, "Maximum sendings per day"%> <%=f.number_field :maxSendingsDayAll%></br> <%=f.label :maxSendingsTotalAll, "Maximum sendings"%> <%=f.number_field :maxSendingsTotalAll%></br> <%=f.label :maxSendingsDeviceAll, "Maximum sendings per device"%> <%=f.number_field :maxSendingsDeviceAll%></br> <%=f.label :maxSendingsDeviceTotal, "Maximum sendings per device per day"%> <%=f.number_field :maxSendingsDeviceTotal%></br> <%=f.label :updateInterval, "Action resend interval"%> <%=f.number_field :updateInterval%></br> <%= f.submit "Create Action", class: "btn btn-large btn-primary" %> <%end%> </div> </div> <script type="text/javascript"> $('.datetimepicker').datetimepicker({ language: 'en', }); $("#action_noteType").select2({ width: "470px" }); </script> I know it is not good style to post so much code and asking for a perfect solution. But I worked several days on this problem, and don't know how to solve it :( Thanks for your help -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
