This is a very small, simple piece of code, but essential for using fields of type 'money' on MS SQL Server, through FreeTDS. This took me quite some time to hunt down, as get_placeholder() is in fact an undocumented feature.

Example:

class MyModel(models.Model):
    price = MoneyField()

from django.db import models

class MoneyField(models.DecimalField):
    
    def __init__(self, *args, **kwargs):
        # Default to the max size for SQL Server's money datatype
        kwargs['max_digits'] = kwargs.get('max_digits', 20)
        kwargs['decimal_places'] = kwargs.get('decimal_places', 2)
        super(MoneyField, self).__init__(*args, **kwargs)
    
    def get_placeholder(self, value):
        return r'CONVERT(money, %s)'
