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

Hope this helps.
Thank you for the reply.And what i understood is that, the self.env environment reference allows us to access any other model. For example, self.env['res.partner'] returns a reference to the Partners model. We can then use search() or browse() on it to generate recordsets.
self.env['model.name'] is used instead of self.pool.get('model.name') in the old api, to access the recordset of a particular model. In the old api, with search and browse you had pass cr, uid, context seperately, whereas with self.env it is implicit.
An environment wraps data for ORM records:
'cr', the current database cursor.
'uid', the current user id.
'context', the current context dictionary.

It's a shame the link from www.mindissoftware.com is returning a 404.
