Django Makemigrations and Migrate keep repeating

Question

Something seems to be occurring with my django app. There are two models, one where I altered and the other a new addition. Ever since these two changes my makemigrations and migrate has continued to be the same changed with the migration number incrementing. When I makemigrations:

Migrations for 'om':
  0033_auto_20200122_0001.py:
    - Alter field delivery_date on growerpurchaseorderitem
Migrations for 'accounts':
  0105_auto_20200122_0001.py:
    - Alter field created on pushtoken
    - Alter field push_token on pushtoken

And when I migrate

Synchronizing apps without migrations:
  Creating tables...
    Running deferred SQL...
  Installing custom SQL...
Running migrations:
  Rendering model states... DONE
  Applying accounts.0105_auto_20200122_0001... OK
  Applying om.0033_auto_20200122_0001... OK

I have tried to fake a migration to get past this but no luck. It is an issue as any new changes are not registering to my models.

EDIT:

Show migrations:

for my om

[X] 0030_auto_20200121_2339
 [X] 0031_auto_20200121_2343
 [X] 0032_auto_20200121_2348
 [X] 0033_auto_20200122_0001

for my accounts

[X] 0099_certpdf_expiration_date
 [X] 0100_pushtoken
 [X] 0101_auto_20200121_2145
 [X] 0102_auto_20200121_2339
 [X] 0103_auto_20200121_2343
 [X] 0104_auto_20200121_2348
 [X] 0105_auto_20200122_0001

@HarshNagarkar unfortunately, no. I don't have that in my meta — Andy Nguyen, Jan 22 '20 at 00:58
Do your model fileds have changing default values, like for example `datetime.now()`? — Klaus D., Jan 22 '20 at 01:34
@KlausD. yes. I have used that before though. Is it the issue? — Andy Nguyen, Jan 22 '20 at 01:56
Most likely. Try to remove the parentheses! Django should do the call if needed only. — Klaus D., Jan 22 '20 at 02:11
fixed it. turns out when i went to remove the parentheses i found that i also had something along the lines of `blank=true,null=true` causing this to happen. Thank you @KlausD. — Andy Nguyen, Jan 22 '20 at 17:56

According to my research, this is most likely the point where the program gets awry:

Synchronizing apps without migrations:

Try creating the migrations and then fake the first migration:

python manage.py makemigrations <app_name>
python manage.py migrate --fake-initial

Where the commands will skip any migration where the tables were already created.

P.S. If you don't know what fake migrations are, check out the explanation.

Whatever the problem with migrate, just delete lastly auto created files in the migrations folder and do it again.

You can also edit it directly and run:

python manage.py makemigrations

python manage.py migrate
