Apr 13, 2026
Introduction
In the enterprise planning resources systems, Odoo is the most flexible and easy-to-use platform for developers. The key to Odoo lies in its Object-Relational Mapping (ORM) system. It is essential to undergo the Odoo Training for the ERP professional to understand Odoo ORM. This post will highlight the key concepts, methods, and real-life use cases of Odoo.
Briefing Odoo ORM
A programming method is called Odoo Object-Relational Mapping. ORM connects relational databases and object-oriented programming. It helps developers work with database records as Python objects instead of writing raw SQL queries.
Let's explain it simply -
Tables → Models
Rows → Records
Columns → Fields
Working in this way increases efficiency without mistakes and balances accuracy among applications.
Importance of Object-Relational Mapping
Developers pursuing Odoo Certification try to understand ORM while working with Odoo. Because Odoo ORM has many significance.
A. ORM removes the complicated SQL queries.
B. It ensures the authenticity and security of data.
C. It helps to accelerate the development cycles.
D. Odoo ORM offers modular and reusable code.
E. It can automatically handle relationships.
Concepts of Odoo ORM
1. Models
Models are like database tables. A Python class is used to define each model.
from odoo import models, fields
class Student(models.Model):
_name = 'student.record'
name = fields.Char(string="Name")
age = fields.Integer(string="Age")
2. Fields
In a model, the information is organized by the Fields.
The most common types of Fields are:
Char – Text
Integer – Numbers
Float – Decimal values
Boolean – True/False
Date, Datetime
Many2one, One2many, Many2many – Relationships
3. Recordsets
Odoo Object Relational Mapping uses groups of records, which are called recordsets. It does not work with individual rows or one record at a time.
students = self.env['student.record'].search([])
4. Environment (env)
The env object gives access to
Database cursor
User context
Models
self.env['res.users']
5. Domains
Domains are actually filters that help to find out the records.
students = self.env['student.record'].search([('age', '>', 18)])
Approach of ORM in Odoo
1. Create Method - Create Method is used to add new records to the database.
self.env['student.record'].create({
'name': 'John',
'age': 20
})
2. Read Method - This technique is used to retrieve information from documents.
record.read(['name', 'age'])
3. Write Method - It updates the records of already existing documents.
record.write({'age': 22})
4. Unlink Method - This method is applied when we need to remove any records.
record.unlink()
5. Search Method - Search technique uses the domain filters to get back records.
records = self.env['student.record'].search([('name', '=', 'John')])
6. Browse Method - The browse method retrieves records with the help of identities.
record = self.env['student.record'].browse(1)
7. Search Count - The Search Count gives back the exact number of records that we are looking for.
count = self.env['student.record'].search_count([])
Real-World Application of ORM
I. Odoo ORM is used for CRM development, like:
Keeping track of leads and opportunities
Follow-up automation
Monitoring consumer interactions
II. It is used for handling the stock.
Current stock information
Automation of warehouses
Monitoring suppliers
III. Object-Relational Mapping can manage finances and accounts.
Invoice generation
Financial reporting
Tax calculations
IV. It helps the human resources department to manage
Records of employees
Payroll administration
Checking attendance
V. Odoo ORM is the best solution for E-Commerce platforms. It helps in
Product catalogues
Order fulfilment
Handling of customer data
In the practical classes of Odoo Training, these use cases are included to prepare the trainees.
Conclusion
Odoo ORM helps developers to create precise and scalable databases. ORM makes development faster and easier with features like CRUD operations, computed fields, and inheritance. A proficient developer with Odoo Certification can build a reliable business application by learning Odoo ORM.
