I have a local python environment working, but when I try and load in initial data.
python manage.py loaddata initial_data.json
I get an error about "RemovedInDjango18Warning"?
I am not a python dev to say - so this error is new to me.
C:\Python27\aasoo>python manage.py loaddata initial_data.json

You should rename get_query_set to get_queryset in SearchManagerMixIn. Can you paste the definition of the class if you need more help.

I deleted some migration files that were giving me the error.
Then when I write "python3 manage.py showmigrations" I get the following error:

How to fix it?
If you have such an error at the development stage, then I don’t know if this is correct, but I would probably delete all the migrations of the conflicting application and the database too, and then run "python manage.py makemigrations"
(Sorry, comments are not available to me)

Does anyone know the answer? If so please help!

Are you following a tutorial? If so, please share it with us. There may be a problem with your python installation. Please delete all python installations on your computer and install the latest version. Then create django project again.
I'm attempting to upgrade Django from 1.10.7 to 1.11.4 with Python 2.7.11. I've run pip install Django -U and python -c "import django; print django.get_version()" confirms that Django 1.11.4 is installed. However, when I then go to run tests, I get ImportError: No module named notmigrations. Does anyone have any advice?

It looks like you are using notmigrations in your MIGRATION_MODULES setting to disable migrations (as described in this post).
In Django 1.9+, you should simply use None instead of a fake module name like 'notmigrations' (release notes).
For Django 2.0 I create setting file as described here with content like:
from settings import *
class DisableMigrations(object):
def __contains__(self, item):
return True
def __getitem__(self, item):
return None
MIGRATION_MODULES = DisableMigrations()
and run my tests with test newly created setting
I have created a custom User model in Django. Now, I want to run my application on heroku. But I can't run migrate, code error:
ValueError: Dependency on app with no migrations
How can I solve this problem?

I have made migrations locally and add "0001_initial.py" file to git.
Now it works fine.
I have some tests in myproject/core/tests/test_views_front.py. When I try to run python manage.py test myproject.core.tests.test_views_front I get:
NOTE: Using test database settings!
NOTE: Logging is disabled!

This also happens if I run python manage.py test myproject.core.tests.test_views_front.FrontPageViewTests. However, if I simply run python manage.py test or python manage.py test myproject.core.tests then all the tests (including the ones in the aforementioned file) run fine. I found this solution but my test file seems to import fine, without any errors or warnings. Is there anything else I might be missing?
You can't run test from a specific file in Django. You can either run all the test from myproject.core.tests like you did or a specific TestCase:
myproject.core.tests.YourTestCase
