Getting values from models misunderstanding

Question

I'm learning a custom module from the net and I'm seeing the sentence like this in a method:

/'partner_id': order.partner_shipping_id.id/

I know that this sentence is used to derive any information from the model - sale.order (order = sale.order), and partner_shipping_id is the field in the model. Could anybody explain what is id here? the id of the field? but it could be not id. maybe it could be name in the end of sentence. Thanks

Hello Vladislav,

*'partner_id': order.partner_shipping_id.id*

*partner_id* is *Many2one field* in the model. Hence it requires a *id* of its table.

lets print evrything one by one-

print *order*
/O/P : (sale.order,1) /
sale.order is object
1 is the id in sale.order table

print *order.partner_shipping_id*
/O/P:(res.partner,12)/
res.partner is object
12 is the id in res.partner table

print *order.partner_shipping_id.id*
/O/p :12/
12 which is id in res.partner table

/Input:/
*'partner_id':
