Hi all, I need to inherit parent class attributes and functions to  a child class but to create a child entry, i have to create first the parent reference and child attribut (here: amount and is_active).

I would like to automatically create the parent object and  child from on form. ie a form with name, code, amount and is_active

We put all required attributes and asked odoo to create parent and child references.

Any suggestion please ?

Best regards

PS: I'm using odoo15

class ParentModel(models.Model):
_description = "Parent "
_name = "generic.parent"
name = fields.Char("Name", required=True)
code = fields.Char("Code", default="/", required=True)


class ChildModel(models.Model):
_description = "Child Model"
_inherits = {'generic.parent': 'parent_id'}
_name = "child.name"
amount = fields.Float("amount", default=0.0)
is_active = fields.Boolean("Is Active ?", default=False, required=True)
parent_id = fields.Many2one('generic.parent', string='Parent ID', ondelete='cascade')

Inheritance in odoo models is not like the abstraction of other python frameworks such as Django and etc. The closest solution is for ParentClass to inherit from AbstractModel like:

class ParentModel(models.AbstractModel):
    _name = "generic.parent"
    name = fields.Char("Name", required=True)
    code = fields.Char("Code", default="/", required=True)


class ChildModel(models.Model):
  _inherit = 'generic.parent'
    amount = fields.Float("amount", default=0.0)
    is_active = fields.Boolean("Is Active ?", default=False, required=True)
