  • i18n/de.po: German translation
  • security/ir.mode.access.csv: Access groups and permissions

Odoo Architecture

  • Powered by Python and PostgreSQL
  • Model-View-Controller
  • API: XML-RPC

Logical Architecture

Odoo's ORM

Object Relation Mapping^2.

  • Manages models and business logic
  • Internal registry loads module definitions
  • Methods to interact with data

Everything is XML

Every view is defined as XML.

Forms, lists, pages, filters, fields, menus, records, ...

Extending Odoo

Odoo can be extended easily

  • Inherit a model and change business logic
  • Change XML-structure and update views

Inherit a Model

from odoo import models

class ProductProduct(models.Model):
    _inherit = "product.product"

    _sql_constraints = [
        (
            "default_code_uniq",
            "unique(default_code)",
            "Internal Reference must be unique across the database!",
        )
    ]
