Major form validation/submitting problem.

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

    <%=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 :frowning: Thanks for your help
