Overview

This module ensures data integrity in your Odoo system by preventing the creation of multiple partners with the same email address. It provides both database-level constraints and application-level validation for comprehensive protection against duplicate emails.

Key Features

🔒 SQL Constraint

Database-level UNIQUE constraint ensures email uniqueness at the lowest level.

✅ Python Validation

Additional @api.constrains validation with detailed error messages.

🔍 Case-Insensitive

Email comparison ignores case to catch variations like User@email.com.

📊 Batch Support

Works correctly with import operations and batch record updates.

How It Works

When a user attempts to create or update a partner with an email address that already exists in the system, they will see a clear error message:

"A partner with email 'example@domain.com' already exists: John Doe"
