What is an external id and where we can use it in Odoo?

If anyone knows what an external id is, and what are its uses, I will be thankful.

I didn't find resources about that on the web.

Thanks in advance.

By debug mode then go the the form of the recod then view metadata from the Debug icon in the top left.
You can find it in the database by YOUR_MODEL and ID in the request:

select module,name
from ir_model_data
where model = 'YOUR_MODEL' and res_id=ID

An External ID, also known as an XML Id, is an identifier for a data record. Odoo uses a base Model, ir.model.data, to map identifiers with the corresponding actual database IDs.

Whenever an External Id is referenced by another data record, or by some server-side Python code, ir.model.data allows to translate that string identifier into the specific record ID used for it in this particular database.

get_external_id

is kinda crap and may not return an id: it just gets a random existing xid but won't generate one if there is no xid currently associated with the record. And operating with xids isn't exactly fun in RPC.

Example: 

# backwards compatibility
get_xml_id = get_external_id
_get_xml_ids = _get_external_ids
