Highlights

Related fields

Mirror a value through a dotted path — no SQL column:

company_currency_id = Many2one(
    "res.currency",
    related="company_id.currency_id",
)

• Read: partner.company_currency_id → partner.company_id.currency_id
• Write: updating the related field updates the company's currency_id
• Paths: Many2one hops only (e.g. company_id.currency_id)
• Types: related field must match the leaf (Many2one → Many2one, etc.)

Field readonly

internal_ref = Char(readonly=True)

• write() and attribute assignment raise ValueError
• Edit forms disable the input unless the view sets readonly=False
