How to Apply o2m dynamic domain

Hello odooers  & developers, 

Its odoo tips and tricks article, where I would like to share more knowledge about the o2m dynamic domain in Odoo 17

as an odoo developer, knowing the fundamentals of o2m Dynamic Domain Filtering in Odoo behaviour, its Syntax, and how we can use the o2m dynamic domain in Odoo is essential.  

Explore o2m Dynamic Domain Method :-

This code sets up a dynamic domain for the O2M field.

"domain=lambda self: self._compute_child_domain()": This is the key part. It sets the domain for the O2M field. Here, it uses a lambda function to dynamically call the _compute_child_domain method whenever the domain needs to be evaluated. This ensures the domain is updated based on the current record's "status" and model.

o2m Dynamic Domain Method Usage and Syntax:- 

    def _compute_child_domain(self):

        for record in self:

            return [('model', '=', record._name)]

review_ids = fields.One2many(

        comodel_name='approval.request', inverse_name='res_id',

        string='Validations',

        auto_join=True,

        domain=lambda self: self._compute_child_domain()
