Learn how to use the Write ORM method in Odoo to update existing records efficiently with examples and best practices.

Odoo Write ORM Method

The Write ORM method in Odoo is a powerful tool that allows developers to update existing records in the database. This method is part of Odoo's Object-Relational Mapping (ORM) capabilities, which simplify database interactions and enhance productivity.

Understanding the Write Method

The write method is used to modify the fields of existing records. It takes a dictionary of field names and their new values as an argument. The method can be called on a recordset, which can include one or more records.

Basic Syntax

The basic syntax for the write method is as follows:

python
recordset.write({'field_name': new_value})

Example Usage

Here's an example of how to use the write method in Odoo:

python

# Assume we are updating the name of a partner
partner_id = self.env['res.partner'].browse(1)  # Fetch the partner with ID 1
partner_id.write({'name': 'New Partner Name'})  # Update the name

In this example, we fetch a partner record with ID 1 and update its name to "New Partner Name" using the write method.

Updating Multiple Records

You can also update multiple records at once. For example:

python

# Update multiple partners
partner_ids = self.env['res.partner'].search([('country_id', '=', country_id)])  # Fetch partners in a specific country
partner_ids.write({'active': False})  # Deactivate all fetched partners

In this case, all partners from a specific country are fetched and marked as inactive.

Best Practices

When using the write method, consider the following best practices:

  • ▹ Always check for the existence of records before attempting to write to them.
  • ▹ Use the write method judiciously to minimize database write operations.
  • ▹ Implement necessary business logic or validation before updating records.

Conclusion

The Write ORM method is an essential tool in Odoo for developers who need to update records efficiently. By understanding its syntax and best practices, you can enhance your Odoo applications and ensure optimal performance.
