Few files needs to be created compulsory. We will take an example let say – “test_module”

First of all, we will see the architecture of a typical OpenERP module.

  3. Python files
  4. XMLFiles
    1. Actions
    2. Menu Entries
    3. Reports
    4. Wizards

All the modules are located in server/addons directory.

The following steps are necessary to create a new module “test_module”:

– create a subdirectory in the server/addons directory having module name test_module.

– create a module description file:

– create the Python file containing the objects.

– create .xml files that download the data (views, menu entries, demo data, …).

– optionally create reports, wizards or workflows.

We will see each files introduction one by one.

The file:

The file is, like any Python module, executed at the start of the program. It needs to import the Python files that need to be loaded.

So, if you create a “” file, containing the description of your objects, you have to write one line in


The file

In the created module directory, you must add a file. This file, which must be in Python format, is responsible to

  1. determine the XML files that will be parsed during the initialization of the server, and also to
  2. determine the dependencies of the created module.

This file must contain a Python dictionary with the following values:

"name" : "Test Module",
"version" : "1.1",
"author" : "Open",
"category" : "Test Base/Test Base",
"depends" : ["base"],
"init_xml" : [],
"demo_xml" : [],
"update_xml" : ["test_view.xml"],
"installable": True,
"active": True

The file

from osv import osv

from osv import fields

class test_base(osv.osv):

    ”’Test Base Class”’







The text_view.xml file

<?xml version=“1.0” encoding=“utf-8”?>

            <field name=“view_type”>form</field>

            <field name=“view_mode”>tree,form</field>


        <menuitem id=“menu_test_base_main” name=“Test Base”/>

        <menuitem id=“menu_test_base” parent=“menu_test_base_main”

                  name=“Test Base” action=“action_test_seq”/>
