Type Of model Inheritance in odoo:<\/span><\/span><\/p>\n

Inheritance by extension:<\/span><\/p>\n

<\/p>\n

<\/p>\n

from odoo import models, fields, api<\/span><\/p>\n


<\/span><\/p>\n

class ParentModel(models.Model):<\/span><\/p>\n

    _name = ‘parent.model’<\/span><\/p>\n

    <\/span><\/p>\n

    name = fields.Char()<\/span><\/p>\n

    age = fields.Integer()<\/span><\/p>\n

    <\/span><\/p>\n

    @api.multi<\/span><\/p>\n

    def do_something(self):<\/span><\/p>\n

        # some functionality<\/span><\/p>\n

        pass<\/span><\/p>\n


<\/span><\/p>\n

class ChildModel(models.Model):<\/span><\/p>\n

    _name = ‘child.model’<\/span><\/p>\n

    _inherit = ‘parent.model’<\/span><\/p>\n

    <\/span><\/p>\n

    email = fields.Char()<\/span><\/p>\n

    <\/span><\/p>\n

    @api.multi<\/span><\/p>\n

    def do_something(self):<\/span><\/p>\n

        # overriding parent method<\/span><\/p>\n

        pass<\/span><\/p>\n

In this example, the ChildModel inherits from the ParentModel using the _inherit attribute. The child model also adds a new field email and overrides the do_something method of the parent model.<\/span><\/p>\n


<\/span><\/p>\n

Inheritance by delegation:<\/span><\/p>\n

<\/p>\n

from odoo import models, fields, api<\/span><\/p>\n


<\/span><\/p>\n

class ParentModel(models.Model):<\/span><\/p>\n

    _name = ‘parent.model’<\/span><\/p>\n

    <\/span><\/p>\n

    name = fields.Char()<\/span><\/p>\n

    age = fields.Integer()<\/span><\/p>\n

    <\/span><\/p>\n

    @api.multi<\/span><\/p>\n

    def do_something(self):<\/span><\/p>\n

        # some functionality<\/span><\/p>\n

        pass<\/span><\/p>\n


<\/span><\/p>\n

class ChildModel(models.Model):<\/span><\/p>\n

    _name = ‘child.model’<\/span><\/p>\n

    <\/span><\/p>\n

    parent_id = fields.Many2one(‘parent.model’)<\/span><\/p>\n

    email = fields.Char()<\/span><\/p>\n

    <\/span><\/p>\n

    @api.multi<\/span><\/p>\n

    def do_something(self):<\/span><\/p>\n

        # some functionality delegated to parent model<\/span><\/p>\n

        self.parent_id.do_something()<\/span><\/p>\n

        pass<\/span><\/p>\n

In this example, the ChildModel does not inherit from the ParentModel. Instead, it creates a Many2one field parent_id to delegate some of its functionality to the ParentModel. The child model also adds a new field email and overrides the do_something method to delegate some functionality to the parent model.<\/span><\/p>\n


<\/span><\/p>\n

Inheritance by prototype:<\/span><\/p>\n

from odoo import models, fields, api<\/span><\/p>\n


<\/span><\/p>\n

class ParentModel(models.Model):<\/span><\/p>\n

    _name = ‘parent.model’<\/span><\/p>\n

    <\/span><\/p>\n

    name = fields.Char()<\/span><\/p>\n

    age = fields.Integer()<\/span><\/p>\n

    <\/span><\/p>\n

    @api.multi<\/span><\/p>\n

    def do_something(self):<\/span><\/p>\n

        # some functionality<\/span><\/p>\n

        pass<\/span><\/p>\n


<\/span><\/p>\n

class ChildModel(models.Model):<\/span><\/p>\n

    _name = ‘child.model’<\/span><\/p>\n

    <\/span><\/p>\n

    _inherits = {‘parent.model’: ‘parent_id’}<\/span><\/p>\n

    parent_id = fields.Many2one(‘parent.model’)<\/span><\/p>\n

    <\/span><\/p>\n

    email = fields.Char()<\/span><\/p>\n

    <\/span><\/p>\n

    @api.multi<\/span><\/p>\n

    def do_something(self):<\/span><\/p>\n

        # overriding parent method<\/span><\/p>\n

        pass<\/span><\/p>\n

In this example, the ChildModel inherits from the ParentModel using the _inherits attribute to create a copy of the ParentModel. The child model also adds a new field email and overrides the do_something method of the parent model.<\/span><\/p>\n
