demo data in odoo

ODOO

 

demo data here means that records which will insert automatically will we install the module , and in order to do that we have to go to our module then add new folder by name"data" _ as standard _ then inside data add new xml file in which we will add our demo data record by record , so let me give an example 

let us say we have object with name student.py which is contain data about the student "name , age , phone , email"

from openerp import models, fields, api, _

class Student(models.Model):
    _name = 'student'

    """
        contain all student data
    """
    name = fields.Char('Name', required=True)
    age = fields.Integer('Age', required=True)
    phone = fields.Integer('Phone', required=True)

    email = fields.Char('Email', required=True)

then we will create the demo data file by name student_demo.xml as

<?xml version="1.0" encoding="utf-8"?>
<odoo>
    <data noupdate="1">
   
        <!-- Student Demo Data -->
        <record id="student_1" model="student.py">
            <field name="name">A</field>
            <field name="age">15</field>
            <field name="phone">123456</field>
            <field name="email">A@mail.com</field>
        </record>

        <record id="student_1" model="student.py">
            <field name="name">B</field>
            <field name="age">15</field>
            <field name="phone">123457</field>
            <field name="email">B@mail.com</field>
        </record>

        <record id="student_1" model="student.py">
            <field name="name">C</field>
            <field name="age">15</field>
            <field name="phone">123458</field>
            <field name="email">C@mail.com</field>
        </record>

     </data>
</odoo> 

now we create the student "A,B,C" and the will be insert automatically when we install our module
