When you include the to_field, it tells Django that you want the foreignkey to be the to_field on the CustomerProfile. It then looks for a field called payment_id (following the foreignKey relationship). This is normal.
If you remove the to_field, it will choose the primary key of CustomerProfile which is probably an AutoField. Then it will look for CustomerProfile_id which is a field that DOES exist. The point of the ForeignKey option is to link one model to another one *via the primary key*. You don't link to a random field in the model, you always link to the primary key.
