The *Country Module* introduces the following concepts:
|
|
|
|
.. _model-country.country:
|
|
|
|
Country
|
|
=======
|
|
|
|
This is the top level concept provided by the *Country Module*.
|
|
Each country record in Tryton represents a specific country, political state
|
|
or nation.
|
|
|
|
The ISO 3166 standard defines the codes and names of countries and is used when
|
|
`Loading and updating countries and subdivisions`.
|
|
|
|
.. seealso::
|
|
|
|
Countries can be found under the main menu entry:
|
|
|
|
|Administration --> Countries|__
|
|
|
|
.. |Administration --> Countries| replace:: :menuselection:`Administration --> Countries`

|
.. _model-country.subdivision:
|
|
|
|
Subdivision
|
|
===========
|
|
|
|
The *Subdivision* of a `Country <model-country.country>` represents a well
|
|
defined area of that country.
|
|
Subdivisions can be any size, ranging from regions, provinces, states, and
|
|
counties down to municipalities, cities and boroughs.
|
|
|
|
The ISO 3166-2 standard defines codes and names for country subdivisions.
|
|
These are automatically loaded and updated along with the countries.
|
|
|
|
.. _model-country.postal_code:
|
|
|
|
Postal Code
|
|
===========
|
|
|
|
The *Postal Code* concept is used to store postal codes, and their relationship
|
|
to `Countries <model-country.country>`, `Subdivisions
|
|
<model-country.subdivision>` and cities.
|
|
Depending on the country they relate to these codes are known locally as
|
|
either postcodes, post codes, :abbr:`PIN (Postal Index Number)` or
|
|
:abbr:`ZIP (Zone Improvement Plan)` codes.
|
|
|
|
A script is provided for `loading and updating postal codes`.
