Hello,

Reason for Deprecation:

The name_get method was deprecated in Odoo 17 (commit #122085) in favor of a more standardized approach using the display_name field. This change aims to improve code maintainability and consistency across different models.

Alternative Method:

Instead of name_get, you should now access the display_name field directly. This field is designed to provide a human-readable representation of a record, often combining multiple fields for better context.

Here's how to use display_name:

record = self.env['your_model_name'].browse(record_id)
record_name = record.display_name

And override _compute_display_name method: 

• Create a method named _compute_display_name decorated with @api.depends
• Inside the method, define the logic for generating the display name. You can access other fields of the record (self) and combine them as needed.
• Finally, assign the generated string to self.display_name.

#=== COMPUTE METHODS ===#

@api.depends('partner_id')
@api.depends_context('sale_show_partner_name')
def _compute_display_name(self):
    if not self._context.get('sale_show_partner_name'):
        return super()._compute_display_name()
    for order in self:
        name = order.name
        if order.partner_id.name:
            name = f'{name} - {order.partner_id.name}'
        order.display_name = name
And override _compute_display_name method:

  Hope it helps
