Partner first name and last name

This module was written to extend the functionality of contacts to support having separate last name and first name.


You can configure some common name patterns for the inverse function in Settings > Configuration > General settings:

  • Lastname Firstname: For example 'Anderson Robert'
  • Lastname, Firstname: For example 'Anderson, Robert'
  • Firstname Lastname: For example 'Robert Anderson'

After applying the changes, you can recalculate all partners name clicking "Recalculate names" button. Note: This process could take so much time depending how many partners there are in database.

You can use _get_inverse_name method to get lastname and firstname from a simple string and also _get_computed_name to get a name form the lastname and firstname. These methods can be overridden to change the format specified above.


The field name becomes a stored function field concatenating the last name and the first name. This avoids breaking compatibility with other modules.

Users should fulfill manually the separate fields for last name and first name, but in case you edit just the name field in some unexpected module, there is an inverse function that tries to split that automatically. It assumes that you write the name in format configured ("Lastname Firstname", by default), but it could lead to wrong splitting (because it's just blindly trying to guess what you meant), so you better specify it manually.

For the same reason, after installing, previous names for contacts will stay in the name field, and the first time you edit any of them you will be asked to supply the last name and first name (just once per contact).

Known issues / Roadmap

Patterns for the inverse function are configurable only at system level. Maybe this configuration could depend on partner language, country or company, as discussed at this OCA issue

Small missing on signup and user details form
Mathieu C
on 11/3/19, 11:31 AM

Very good module. But is it normal that this module does not apply the change also on the : - signup form ? - user details form ? It would be good if the user can directly insert firstname + lastname while creating its account. How could we implement this ? Thanks and regards

Does this change leads to first and last name too?

I am not sure if they use the same or not
