Learn how the name_create function works in Odoo to quickly create records in many2one fields with just the display name. Enhance your Odoo modules.

Understanding the name_create Function in Odoo

Odoo provides a powerful framework for handling database records, including creating new records in models. One of the lesser-known but very useful methods in Odoo is the name_create function, which simplifies the creation of records in relation fields. In this blog, we’ll dive into the purpose and usage of the name_create function in Odoo.

What is the name_create Function?

The name_create function is a specialized method that Odoo uses when creating a new record in a many2one or similar relational field. When a new value is entered in a relational field, instead of selecting an existing record, Odoo calls the name_create function to create a new record with minimal data. The key benefit of this method is that it allows creating a new record based only on the name or display name.

How name_create Works in Odoo

The name_create method is particularly useful when working with fields like many2one, where you want to quickly create a related record with just the display name. For example, when creating a new partner or product through a relational field, Odoo will use this method to insert the new record with a default name.

The typical structure of the name_create function is:

python

    def name_create(self, name):
        return self.create({'name': name}).name_get()[0]
    

In this code snippet, Odoo creates a new record using the provided name, and then retrieves its name_get value, which will be displayed in the UI.

Example of name_create in a Custom Model

Let’s take a simple example where we implement the name_create method in a custom model. In this case, we want to allow users to quickly create a new record in a many2one field by entering the name directly.

python

    from odoo import models, fields
    class CustomModel(models.Model):
        _name = 'custom.model'
        _description = 'Custom Model'
        name = fields.Char(string='Name', required=True)
        def name_create(self, name):
            return self.create({'name': name}).name_get()[0]
    

Here, when a new value is entered in the many2one field that relates to custom.model, the name_create function will be called, and a new record will be created with just the provided name.

When to Use name_create

The name_create function is useful when you need to allow users to quickly create new records in many2one or other relational fields with minimal data entry. This functionality is often used in scenarios such as:

  • ▹ Creating new customers or products directly from a form without navigating away
  • ▹ Handling quick data entry for reference fields
  • ▹ Improving user experience by streamlining data creation workflows

Conclusion

The name_create function in Odoo is an efficient method for creating records on the fly within relational fields, such as many2one. It allows for quick and simple record creation based on a single field (usually the name), improving user experience and workflow efficiency. Whether you are developing custom modules or working with Odoo’s default models, knowing how to leverage name_create can be incredibly beneficial.
