How to create a basic module in OpenERP 7

It is very easy to create a module in OpenERP 7

•  The following steps are required to create a new module "student" :

1. Create a subdirectory in the .../OpenERP/Server/server/openerp/addons/  that name module "student".
2.  Create a file Module description : __ openerp__.py
3. Create the file containing Python objects : student.py
4. Create .xml file that download data (views, menu items, data show ...) : student_view.xml
5. Finaly create a file Module start : __init__.py

• The __ openerp__.py file :

In the module directory created, you must add a __ openerp__.py file.

This file, which must be Python format is responsible for :

1. Determine the XML files that will be analyzed during the initialization of the server, and also
2. Determine the dependencies of the module created.

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

{

        "name" : "student",

        "version" : "0.1",

        "author" : "rsuna blog",

        "website" : "http://rsuna.blogspot.com/",

        "category" : "Unknown",

        "description": """ OpenERP Module test rsuna blog """,

        "depends" : ['base'],

        "init_xml" : [ ],

        "demo_xml" : [ ],

        "update_xml" : ['student_view.xml'],

        "installable": True

}

• The student.py file :

from osv import fields,osv

class student(osv.osv):

    _name = 'student'

    _columns = {

        'name': fields.char('Name',size=30,required=True, help='the name'),

        'first_name': fields.char('First Name',size=30,required=True, help='the first name'),

        'birth_date': fields.date('Birth Date',size=30,required=True, help='the birth date'),

        'email': fields.char('Email',size=50, help='the email'),

        'phone': fields.integer('Phone',size=30, help='the phone'),

    }

student()

• The student_view.xml file :

<?xml version="1.0"?>

<openerp>

<data>

    <record model="ir.ui.view" id="view_student_form">

        <field name="name">student.form</field>

        <field name="model">student</field>

        <field name="type">form</field>

        <field name="arch" type="xml">

            <form string="student">

                <field name="name" select="1"/>

                <field name="first_name" select="2"/>

                <field name="birth_date" select="0"/>

                <field name="email" select="0"/>

                <field name="phone" select="0"/>

            </form>

        </field>

    </record>

    <record model="ir.ui.view" id="view_student_tree">

        <field name="name">student.tree</field>

        <field name="model">student</field>

        <field name="type">tree</field>

        <field name="arch" type="xml">

            <tree string="student">

                <field name="name"/>

                <field name="first_name"/>

                <field name="birth_date"/>

                <field name="email"/>

                <field name="phone"/>

            </tree>

        </field>

    </record>

    <record model="ir.actions.act_window" id="action_student">

        <field name="name">Student</field>

        <field name="res_model">student</field>

        <field name="view_type">form</field>

        <field name="view_mode">tree,form</field>

    </record>

        <menuitem name="Student/Student" id="menu_student" action="action_student"/>

<menuitem name="Student" id="menu_student_student_item" parent="menu_student" action="action_student"/>

</data>

</openerp>

• The __init__.py file :

The __init__.py  file is like any Python module, executed at the beginning of the program. It needs to import the Python files to be loaded.

So if you create a "student.py" file containing the description of your items, you must write a line in  __init__.py :

- After restarts service openrerp.
go to Configuration -> Module installs, and makes a search in the area of ​​search aver the module name "student"

- Click on install
Congratulation, module installed !!
