    Prevent migration of non-database attributes

By default, when creating migrations, Django will compare all the attributes
of all models and all fields and compare them to the latest migrated state.
This means that changes to attributes like verbose_name, choices,
help_text, and validators cause new migrations to be created - even
though they have no effect on the underlying database.
This is the way Django was designed to behave, but if during development you
have constant changes to those attributes, and would like to prevent them from
generating migrations, use this snippet. Place it anywhere that gets imported
when your project runs (particularly on the command makemigrations).
You may add/remove fields from the list, based on your specific need.

  
## nomigration.py
from django.db.models import Field


IGNORED_ATTRS = ['verbose_name', 'help_text', 'choices', 'validators']
original_deconstruct = Field.deconstruct


def new_deconstruct(self):
    """Replacement for the deconstruct() method that simply ignored the attributes above."""
    name, path, args, kwargs = original_deconstruct(self)
    for attr in IGNORED_ATTRS:
        kwargs.pop(attr, None)
    return name, path, args, kwargs


Field.deconstruct = new_deconstruct
	from django.db.models import Field


	IGNORED_ATTRS = ['verbose_name', 'help_text', 'choices', 'validators']
	original_deconstruct = Field.deconstruct


	def new_deconstruct(self):
	"""Replacement for the deconstruct() method that simply ignored the attributes above."""
	name, path, args, kwargs = original_deconstruct(self)
	for attr in IGNORED_ATTRS:
	kwargs.pop(attr, None)
	return name, path, args, kwargs


	Field.deconstruct = new_deconstruct
