Override Create Method

• To override the create method we have to add a method named create like below. It will override the description field if it is empty.

  @api.model
  def create(self, vals):
      if not vals['description']:
          vals['description'] = "Enter the description here"
      res = super(HospitalAppointment, self).create(vals)
      return res

Generate Sequential Value For Field

• First we have to create a data directory and create a file named appointment_seq.xml. Insert the below code for creating a sequence.

  <record id="seq_appointment" model="ir.sequence">
      <field name="name">Appointment Sequence</field>
      <field name="code">kmhospital.appointment</field>
      <field name="prefix">AS</field>
      <field name="padding">5</field>
      <field name="company_id" eval="False"/>
  </record>

• Check Settings > Technical > Sequences if the sequence is created or not.

• Add a field name to the appointment.py file.

  name = fields.Char(string='Appointment Reference', required=True, copy=False, readonly=True, default=lambda self: _('New'))

• Add this code to the create method.

  if vals.get('name', _('New')) == _('New'):
      vals['name'] = self.env['ir.sequence'].next_by_code('kmhospital.appointment') or _('New')

• Add the code in the appointment_view.xml file inside the sheet tag.

  <div class="oe_title">
      <h1>
          <field name="name"/>
      </h1>
  </div>
