unable to load photos in Django after deploying to heroku - python

I have made a portfolio + blog website using Django. it works perfectly when running it locally but after I deployed it to Heroku, accessing the portfolio redirected me to a 500 server error. I turned on debug mode and when I did the same, it didn't throw a 500 server error, however, the pictures won't load. this is very confusing and help will be very appreciated...

Your settings.py seems fine, try adding this code to project-name/urls.py
from django.conf import settings
from django.conf.urls.static import static
urlpatterns += static(settings.STATIC_URL, document_root=settings.STATIC_ROOT) # add static file URL to django urlpatterns
If your trying to host media files note that Heroku does not support media hosting you might need to connect your Django application with something like amazon s3 bucket. You can find an article about it here.

I have mentioned the STATIC_ROOT above and have also done python manage.py collectstatic. After doing so it makes a static folder in the root where manage.py is located and it also contains all the files the django is unable to find and gives 404. I also tried using gunicorn but still it is not able to serve static files. I donot understand what mistake i am making . Any help will be really appriciated.

Check the ownership of the files. If you load your files as ec_user and try to deliver as www-data with 640 permissions you will have 404s.

Django admin site is not showing default permissions of models

My Django admin site does not show any default permissions of any models. Actually, I checked the database and I can't find any model permission in the auth_permissions table.
I've already run python manage.py makemigrations and python manage.py migrate. I also tried deleting the database and migration files and run two above command again but doesn't work. I've already registered my models in admin.py.
Any other solutions I can try ?

# Register your models here.

admin.site.register(Worker)
admin.site.register(TimeSheet)

In your admin.py you are importing all of your models as from .Model import *. Python is a case-sensitive programming language if you have not manipulated your models.py file as Models.py.
I suppose from .models import * will do the trick

The above solution solves the problem. However, my Models is actually a folder, I've been trying to divide the models into different files which are stored in that folder. So for those who have the same idea, just simply change the folder's name into models and you're good to go :v

Although I just realised I'm trying to deploy a Python / Django application which references some modules that might not be available on Heliohost.org, because this site doesn't allow shell access, please let me know if you come up with the issue.
Thank you very much in advance.

Try changing ALLOWED_HOSTS = [] to
ALLOWED_HOSTS = ['*']

Thank you for your answer. I already tried that and it gives another error saying that it cannot find the template referred in the code. I have modified the paths in the code and also the directory structure.

I already solved it by specifying the absolute path of the html document, instead of relative path. Thank you very much for your help. :-)

Every command works good except python manage.py startapp myapp [or any other app name] ./apps/myapp. Every time I run it command I get this error:
CommandError: 'myapp' conflicts with the name of an existing Python module and cannot be used as an app name. Please try another name.
I found it related with my code in __init__.py file. I mean if I comment all the codes, that error will be disappear.
Why does it happend? How can I solve it?
With Directory
Without Directory

As #juggernaut has stated. The error is happening when you use the character *, which imports everything and hence overwrites some internal.
When you run the command python manage.py startapp myapp xxxx The myapp section conflicts with an existing module and hence causes that error.
Try importing it manually instead of using from .base import * # noqa. This way you only import the modules that you will need and would not lead to any errors.

Django: ImproperlyConfigured The SECRET_KEY setting must not be empty when executing gunicorn

I'm trying to deploy a django application on AWS. I've read all the existing posts regarding the same issue and include the
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "tango_with_django.settings")
in manage.py and wsgi.py but still it does not work.
My project structure is the following one:
--chimpy
-botApp
-settings
-base.py
-production.py
-wsgi.py
-manage.py
These are my files:

As you can see all files point to the settings/production.py file, which imports everything from base.py and I have the secret key in there, but still receive the same error Django: ImproperlyConfigured: The SECRET_KEY setting must not be empty when I try to do:
gunicorn botApp.wsgi:application --bind 0.0.0.0:8001
Many thanks.
