Question

I want the use a field from wizard to my form view.
Let me explain with code:
class CancelAppointmentWizard(models.Model):
_name = "cancel.appointment.wizard"
_description = "Cancel Appointment Wizard"
reason = fields.Text(string="Reason")
and i want the show this "reason" field inside of some form views.
<record id="view_hospital_appointment_form" model="ir.ui.view">
<field name="name">hospital.appointment.form</field>
<field name="model">hospital.appointment</field>
<field name="arch" type="xml">
<form>
<sheet>
<group>
<field name="reason"/>
</group>
</sheet>
</form>
</field>
</record>
but of course this give me error like
hospital.appointment don't have a field like reason.
How can show this field ?
I tried to make a dummy code, i hope i was able to explain my problem.

I assume the wizard is called from the view_hospital_appointment_form. And in the wizard view let say there is a button tag with name attribute, which is this attribute associated to python method in your wizard class.
Wizard view
<record id="view_cancel_appointment_wizard_form" model="ir.ui.view">
<field name="name">cancel.appointment.wizard.form</field>
<field name="model">cancel.appointment.wizard</field>
<field name="arch" type="xml">
<form>
…
…
<footer>
<button name="action_ok" string="Ok" type="object"/>
</footer>
</form>
</field>
</record>
Python method
def action_ok(self):
ids = self.env.context.get('active_ids')
hospital_appointment = self.env['hospital.appointment'].browse(ids)
hospital_appointment.reason = self.reason
return {'type': 'ir.actions.act_window_close'}
