While Odoo ERP customization offers numerous benefits, businesses may encounter challenges such as:
To begin the customization journey, businesses should follow these steps:
In Part 1, we explored the fundamental aspects of Odoo ERP, its role in business process optimization, and the benefits of customization. Now, in Part 2, we will delve into the technical aspects of Odoo ERP customization, including module development, database structure, coding best practices, and integration techniques.
Before diving into customization, it’s crucial to understand Odoo’s architecture. Odoo is built on Python and JavaScript, with a PostgreSQL database at its core. It follows a Model-View-Controller (MVC) architecture, ensuring a clean separation between data, user interface, and business logic.
Custom module development is essential for tailoring Odoo ERP to business needs. Let’s walk through the process of creating a custom module in Odoo.
To develop in Odoo, set up the environment with:
Navigate to Odoo’s Add-ons Directory
cd /odoo/custom_addons
mkdir custom_module
cd custom_module
Define Module Structure
A basic Odoo module contains:
custom_module/
├── __init__.py
├── __manifest__.py
├── models/
│ ├── __init__.py
│ ├── custom_model.py
├── views/
│ ├── custom_model_views.xml
├── security/
│ ├── ir.model.access.csv
├── static/
├── data/
Define Module Manifest (__manifest__.py)
The manifest file describes the module’s metadata:
{
‘name’: ‘Custom Business Module’,
‘version’: ‘1.0’,
‘author’: ‘Your Name’,
‘category’: ‘Custom’,
‘depends’: [‘base’],
‘data’: [
‘security/ir.model.access.csv’,
‘views/custom_model_views.xml’,
],
‘installable’: True,
‘application’: True,
}
Define a Model (custom_model.py)
Models define the structure of business data in Odoo.
from odoo import models, fields
class CustomBusinessModel(models.Model):
_name = ‘custom.business’
_description = ‘Custom Business Module’
name = fields.Char(string=”Name”, required=True)
description = fields.Text(string=”Description”)
active = fields.Boolean(string=”Active”, default=True)
Create XML Views (custom_model_views.xml)
Views define how data is displayed in the Odoo UI.
<odoo>
<record id=”view_custom_business_form” model=”ir.ui.view”>
<field name=”name”>custom.business.form</field>
<field name=”model”>custom.business</field>
<field name=”arch” type=”xml”>
<form string=”Custom Business”>
<group>
<field name=”name”/>
<field name=”description”/>
<field name=”active”/>
</group>
</form>
</field>
</record>
</odoo>
Define Security Rules (ir.model.access.csv)
Security rules define who can access the module.
id,name,model_id:id,group_id:id,perm_read,perm_write,perm_create,perm_unlink
access_custom_business,custom.business,model_custom_business,base.group_user,1,1,1,1
Install the Module
Restart Odoo and install the module:
./odoo-bin -c odoo.conf -u custom_module
This process successfully creates a custom module in Odoo, allowing businesses to extend functionality as needed.
Odoo allows businesses to automate repetitive tasks using:
from odoo import models, fields, api
class InvoiceApproval(models.Model):
_inherit = ‘account.move’
@api.model
def auto_approve_invoices(self):
invoices = self.search([(‘state’, ‘=’, ‘draft’)])
for invoice in invoices:
invoice.action_post() # Auto-post invoices
This script automatically approves draft invoices on a scheduled basis.
Many businesses require integration with external platforms like payment gateways, eCommerce stores, and marketing tools.
Odoo provides a REST API and XML-RPC API for external communication.
import json
import requests
odoo_url = “https://your-odoo-instance.com”
db = “your_db_name”
username = “admin”
password = “your_password”
# Authenticate
response = requests.post(f”{odoo_url}/web/session/authenticate”, json={
“jsonrpc”: “2.0”,
“params”: {“db”: db, “login”: username, “password”: password}
})
session_id = response.json().get(‘result’, {}).get(‘session_id’)
headers = {‘Cookie’: f’session_id={session_id}’}
# Fetch Customers
customers = requests.post(f”{odoo_url}/web/dataset/call_kw”, json={
“jsonrpc”: “2.0”,
“method”: “search_read”,
“params”: {“model”: “res.partner”, “domain”: [], “fields”: [“name”, “email”]}
}, headers=headers)
print(customers.json())
This script retrieves customer data from Odoo using the API.
In Part 2, we explored the technical aspects of customizing Odoo ERP, including module development, API integration, and workflow automation. Now, in Part 3, we will focus on customizing the user interface (UI/UX), reports, dashboards, and mobile responsiveness to enhance usability and decision-making.
Odoo’s UI framework is built using:
A well-designed UI/UX in Odoo ensures better usability, faster navigation, and improved user engagement.
Odoo provides different types of views that can be customized to fit business needs.
Form views are used to edit and create records. Let’s customize a Sales Order form by adding a new field and changing its layout.
Modify the Model (Python File):
from odoo import models, fields
class SaleOrder(models.Model):
_inherit = ‘sale.order’
order_priority = fields.Selection([
(‘low’, ‘Low’),
(‘medium’, ‘Medium’),
(‘high’, ‘High’)
], string=”Order Priority”, default=”medium”)
Modify the Form View (XML File):
<odoo>
<record id=”view_order_form_inherited” model=”ir.ui.view”>
<field name=”name”>sale.order.form.custom</field>
<field name=”model”>sale.order</field>
<field name=”inherit_id” ref=”sale.view_order_form”/>
<field name=”arch” type=”xml”>
<xpath expr=”//group” position=”inside”>
<field name=”order_priority”/>
</xpath>
</field>
</record>
</odoo>
This will add an “Order Priority” dropdown inside the Sales Order form.
List views display multiple records in tabular format. To add a new column in the Sales Order list view:
<odoo>
<record id=”view_sale_order_list_custom” model=”ir.ui.view”>
<field name=”name”>sale.order.list.custom</field>
<field name=”model”>sale.order</field>
<field name=”inherit_id” ref=”sale.view_order_tree”/>
<field name=”arch” type=”xml”>
<xpath expr=”//tree” position=”inside”>
<field name=”order_priority”/>
</xpath>
</field>
</record>
</odoo>
This will show the Order Priority field in the list view.
Kanban views are used for visual management. To customize a Kanban card in Sales Orders:
<odoo>
<record id=”view_order_kanban_custom” model=”ir.ui.view”>
<field name=”name”>sale.order.kanban.custom</field>
<field name=”model”>sale.order</field>
<field name=”inherit_id” ref=”sale.view_order_kanban”/>
<field name=”arch” type=”xml”>
<xpath expr=”//div[@class=’oe_kanban_content’]” position=”inside”>
<div class=”oe_kanban_details”>
<strong>Priority:</strong>
<span t-field=”record.order_priority.raw_value”/>
</div>
</xpath>
</field>
</record>
</odoo>
Now, Sales Orders will display Order Priority in their Kanban cards.
Odoo provides QWeb reports that can be customized or created from scratch.
To add the Order Priority field to the Sales Order PDF report:
Modify the Report Template (XML File):
<odoo>
<template id=”report_saleorder_document_custom” inherit_id=”sale.report_saleorder_document”>
<xpath expr=”//table[@class=’table table-condensed’]/tbody” position=”after”>
<tr>
<td><strong>Order Priority:</strong></td>
<td t-field=”o.order_priority”/>
</tr>
</xpath>
</template>
</odoo>
This will add the Order Priority field in the Sales Order PDF report.
To create a new report, follow these steps:
Define the Report Action (XML File):
<odoo>
<record id=”action_report_custom” model=”ir.actions.report”>
<field name=”name”>Custom Report</field>
<field name=”model”>sale.order</field>
<field name=”report_type”>qweb-pdf</field>
<field name=”report_name”>custom_module.report_custom_template</field>
<field name=”print_report_name”>’Order – %s’ % (object.name)</field>
</record>
</odoo>
Define the Report Template (XML File):
<template id=”report_custom_template”>
<t t-call=”web.html_container”>
<t t-foreach=”docs” t-as=”o”>
<div>
<h2>Order Report</h2>
<p><strong>Customer:</strong> <t t-field=”o.partner_id.name”/></p>
<p><strong>Priority:</strong> <t t-field=”o.order_priority”/></p>
</div>
</t>
</t>
</template>
Now, businesses can generate custom PDF reports with detailed information.
Dashboards help in real-time data visualization for better decision-making. Odoo allows:
To add a bar chart of orders grouped by priority:
<odoo>
<record id=”view_sale_order_graph_custom” model=”ir.ui.view”>
<field name=”name”>sale.order.graph.custom</field>
<field name=”model”>sale.order</field>
<field name=”arch” type=”xml”>
<graph string=”Sales Order Priority” type=”bar”>
<field name=”order_priority” type=”row”/>
<field name=”amount_total” type=”measure”/>
</graph>
</field>
</record>
</odoo>
This will display a bar chart grouping Sales Orders by priority.
Odoo’s web views are mobile-friendly, but for better performance:
<field name=”arch” type=”xml”>
<form string=”Custom Form”>
<group class=”col-sm-12 col-md-6″>
<field name=”name”/>
<field name=”order_priority”/>
</group>
</form>
</field>
This ensures responsive behavior on different screen sizes.
In Part 3, we explored UI/UX customization, reports, dashboards, and mobile responsiveness. Now, in Part 4, we will focus on security, performance optimization, and deployment strategies to ensure that an Odoo ERP system is robust, scalable, and efficient.
Security is a critical aspect of ERP systems since they manage sensitive business data. Odoo provides multiple security features, including access control lists (ACLs), record rules, user roles, encryption, and audit logging.
Odoo allows administrators to assign access rights based on user roles. This prevents unauthorized access and ensures that employees only see the information relevant to their roles.
To create a new security group, add the following in an XML file:
<odoo>
<record id=”group_sales_manager” model=”res.groups”>
<field name=”name”>Sales Manager</field>
<field name=”category_id” ref=”base.module_category_sales”/>
</record>
</odoo>
This creates a “Sales Manager” role. Next, we need to assign access control lists (ACLs).
ACLs define which actions (read, write, create, delete) users can perform on different models.
To restrict normal users from deleting sales orders, create an ACL file:
id,name,model_id:id,group_id:id,perm_read,perm_write,perm_create,perm_unlink
access_sale_manager,sale.order,model_sale_order,group_sales_manager,1,1,1,1
access_sale_user,sale.order,model_sale_order,base.group_user,1,1,1,0
Now, only users with the Sales Manager role can delete sales orders.
Record rules define which specific records a user can access.
For example, to restrict salespersons to only see their own sales orders, create a rule:
<odoo>
<record id=”sale_order_own_rule” model=”ir.rule”>
<field name=”name”>Salesperson Own Orders</field>
<field name=”model_id” ref=”sale.model_sale_order”/>
<field name=”domain_force”>[(‘user_id’, ‘=’, user.id)]</field>
<field name=”groups” eval=”[(4, ref(‘sales_team.group_sale_salesman’))]”/>
</record>
</odoo>
This ensures that each salesperson can only access their own sales orders.
You can also restrict access to specific fields by defining security groups in the model:
from odoo import models, fields
class SaleOrder(models.Model):
_inherit = ‘sale.order’
confidential_notes = fields.Text(string=”Confidential Notes”, groups=”group_sales_manager”)
Now, only Sales Managers can view this field.
To enhance security:
A well-optimized Odoo system ensures fast response times, smooth operations, and scalability. Performance tuning involves database optimization, caching, load balancing, and server configuration.
Since Odoo relies heavily on PostgreSQL, optimizing the database improves performance significantly.
Adding an index to commonly searched fields improves query speed:
CREATE INDEX idx_order_priority ON sale_order (order_priority);
This makes filtering by Order Priority much faster.
Odoo benefits from connection pooling, which reduces latency. Install and configure pgbouncer:
sudo apt install pgbouncer
Then configure /etc/pgbouncer/pgbouncer.ini:
[databases]
odoo = host=localhost dbname=odoo user=odoo password=your_password
[pgbouncer]
max_client_conn = 100
This allows multiple connections to be handled efficiently.
Odoo can be optimized using Redis for caching.
Install Redis:
sudo apt install redis-server
Configure Odoo to use Redis caching in odoo.conf:
[options]
cache = redis
redis_host = localhost
This significantly speeds up page loads and backend processing.
For high-traffic environments, use NGINX as a load balancer:
upstream odoo_backend {
server 127.0.0.1:8069;
}
server {
listen 80;
server_name yourdomain.com;
location / {
proxy_pass http://odoo_backend;
proxy_set_header X-Forwarded-Host $host;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
}
This allows multiple Odoo instances to share the load, improving scalability.
Once Odoo is secured and optimized, it’s time to deploy it to production.
Install Required Dependencies:
sudo apt update
sudo apt install python3-pip postgresql nginx
Download and Install Odoo:
git clone https://github.com/odoo/odoo.git –branch 16.0
cd odoo
pip3 install -r requirements.txt
Configure Odoo Service File (/etc/systemd/system/odoo.service):
[Unit]
Description=Odoo Service
After=network.target
[Service]
User=odoo
ExecStart=/usr/bin/python3 /home/odoo/odoo/odoo-bin –config=/etc/odoo.conf
Restart=always
[Install]
WantedBy=multi-user.target
Start the Odoo Service:
sudo systemctl enable odoo
sudo systemctl start odoo
To enable SSL encryption, use Certbot with NGINX:
sudo apt install certbot python3-certbot-nginx
sudo certbot –nginx -d yourdomain.com
This automatically configures SSL for Odoo.
To deploy Odoo with Docker, use the following Docker Compose file:
version: ‘3’
services:
odoo:
image: odoo:16
ports:
– “8069:8069”
environment:
– HOST=db
– USER=odoo
– PASSWORD=odoo
db:
image: postgres:13
environment:
– POSTGRES_USER=odoo
– POSTGRES_PASSWORD=odoo
– POSTGRES_DB=odoo
Run Odoo using:
docker-compose up -d
This provides fast and scalable deployment.
