Hi,

You can achieve it easily as follows:


currency_id = fields.Many2one('res.currency', default=lambda self: self.env.company.currency_id, readonly=True)


Thanks & Regards

Hello,

In Odoo, you can access the current company object by calling ".company" from the "env" object. For example, "self.env.company" will return the current company. The company object has a field called "currency_id" which contains the default currency ID.

To select the default company in a field, you can use a lambda function. Here's an example:

currency_id = fields.Many2one('res.currency', default=lambda self: self.env.company.currency_id, readonly=True)

Regards
