Basically, I want to add(patch in) a new Field Option as in here https://docs.djangoproject.com/en/1.10/ref/models/fields/#field-options to the base Field class, so it applies to all other fields
An optional parameter called 'js_inputmask' that is just a string that will be used by a javascript library, for example :
class MyModel(models.Model):
phone = models.IntegerField(verbose_name='Phone Number', js_inputmask='(99) 9999-9999')
How can I add such? I've heard of monkey patch but not sure how to do it in constructors
