Hi,
env(Environment) in new API is to provide an encapsulation around cursor, user_id, model, and context, Recordset and caches.
It evades the use of infamous function signature *def afun(self, cr, uid, ids, context=None):* and in new API its *def afun(self):*
And if you want to call ORM method directly from an object you can use *self.env['obj'].method* instead of *self.method*
An environment wraps data for ORM records:
'cr', the current database cursor.
'uid', the current user id.
'context', t
