Custom Validator to Prevent an appointment from being scheduled too early in day?


Custom Validator to Prevent an appointment from being scheduled too early in day?

hop of those help? You can create your own, the same way active record does. This results in clean, portable, easy to test custom validations. An example might look like:
create app/validators/during_business_hours_validator.rb with:
code :
class DuringBusinessHoursValidator < ActiveModel::EachValidator

  def validate_each(record, attribute, value)
    # example - do whatever you want here
    unless value.present? && during_business_hours(value)
      record.errors[attribute] << 'must be during business hours'
    end
  end

  def during_business_hours(time)
    # from http://stackoverflow.com/q/10090962/525478
    Range.new(
      Time.local(time.year, time.month, time.day, 6, 30),
      Time.local(time.year, time.month, time.day, 21)) === time
  end

end
validates :appointment_date,
          during_business_hours: true

it should still fix some issue Everything looks ok althought I am not sure why you are attaching the Click function to your submit button. I would remove that and test it as it maybe be overriding the default behavior.
Also I think you need to capitalize the IsValid property:
code :
args.IsValid = false;

hop of those help? I had the same problem a while ago. You need a scope :overlapping, that reads overlapping appointments for an appointment and a validator to check. This example is for a PostgreSQL DB. You have to adjust it for your DB, if you're using another DB.
code :
class Appointment < ActiveRecord::Base

  belongs_to :member
  belongs_to :trainer

  validate :overlapping_appointments

  scope :overlapping, ->(a) {
     where(%q{ (appointment_at, (appointment_at + duration)) OVERLAPS (?, ?) }, a.appointment_at, a.appointment_to)
    .where(%q{ id != ? }, a.id)
    .where(trainer_id: a.trainer.id)
  }

  def find_overlapping
    self.class.overlapping(self)
  end

  def overlapping?
    self.class.overlapping(self).count > 0
  end

  def appointment_to
    (appointment_at + duration.hour.hours + duration.min.minutes + duration.sec.seconds).to_datetime
  end

  protected

  def overlapping_appointments
    if overlapping?
      errors[:base] << "This appointment overlaps with another one."  
    end
  end

end

I think the issue was by ths following , I solved the problem after thinking about it anew. I discarded my previous method and wrote a new one:
code :
  private

  def today_appointment
    self.date == Date.current    
  end  
validates_time :starts_at, :after => :now, :if => :today_appointment

To fix this issue First check BaseValidator.php file Path. it's correct or Not.
If BaseValidator.php file Path is correct and after added this all changes you need to once Install / Un-install extension and clear Install Tool cache.

I wish did fix the issue. Adding an error just to the field without specifying the rule I don't think will work, that's why the message from the validation request takes precedence.
So change it to this:
code :
$validator->errors()->add('status.appointment_status', __('Invalid status for an appointment in past'))
