How to fix heroku app deployment? App runs locally but not online
I'm trying to deploy a dog breed classifier django app on heroku, but for some reason heroku doesn't seem to find the path to the exported pkl model file. Whenever I run locally, everything works fine. I'm using the "path" module's "exist()" method to check for the presence of the file first before importing the module, hence the reason for the exception thrown. Here's the stack trace for the error: Environment: Request Method: GET Request URL: https://mydogbreed.herokuapp.com/ Django Version: 3.2.5 Python Version: 3.9.6 Installed Applications: ['django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', 'rest_framework', 'api.apps.ApiConfig', 'corsheaders', 'frontend'] Installed Middleware: ['django.middleware.security.SecurityMiddleware', 'django.contrib.sessions.middleware.SessionMiddleware', 'django.middleware.common.CommonMiddleware', 'django.middleware.csrf.CsrfViewMiddleware', 'django.contrib.auth.middleware.AuthenticationMiddleware', 'django.contrib.messages.middleware.MessageMiddleware', 'django.middleware.clickjacking.XFrameOptionsMiddleware', 'corsheaders.middleware.CorsMiddleware', 'whitenoise.middleware.WhiteNoiseMiddleware'] Traceback (most recent call last): File "/app/.heroku/python/lib/python3.9/site-packages/django/core/handlers/exception.py", line 47, in inner response = get_response(request) File "/app/.heroku/python/lib/python3.9/site-packages/django/core/handlers/base.py", line 167, in _get_response callback, callback_args, callback_kwargs = self.resolve_request(request) File "/app/.heroku/python/lib/python3.9/site-packages/django/core/handlers/base.py", line 290, in resolve_request resolver_match = resolver.resolve(request.path_info) File "/app/.heroku/python/lib/python3.9/site-packages/django/urls/resolvers.py", line 556, in resolve for pattern in self.url_patterns: File "/app/.heroku/python/lib/python3.9/site-packages/django/utils/functional.py", line 48, in __get__ res = instance.__dict__[self.name] = self.func(instance) File "/app/.heroku/python/lib/python3.9/site-packages/django/urls/resolvers.py", line 598, in url_patterns patterns = getattr(self.urlconf_module, "urlpatterns", self.urlconf_module) File "/app/.heroku/python/lib/python3.9/site-packages/django/utils/functional.py", line 48, in __get__ res = instance.__dict__[self.name] = self.func(instance) File "/app/.heroku/python/lib/python3.9/site-packages/django/urls/resolvers.py", line 591, in urlconf_module return import_module(self.urlconf_name) File "/app/.heroku/python/lib/python3.9/importlib/__init__.py", line 127, in import_module return _bootstrap._gcd_import(name[level:], package, … -
Is there a workaround for Django's `ModelDoesNotExist` error in a situation like this?
So I get a ModelDoesNotExist error when I run manage.py runserver because in a file in my directory, I make a query to a table which has not been populated yet. def __init__(self): self.spotify_object = SocialToken.objects.get(account__provider="spotify") The above is a class instantiated to perform some sort of authentication and the SocialToken table gets populated only after I login. Now, I was wondering if there was a way to escape the error by triggering this part of the code only after I login? I only use the class in an endpoint, and during that period, the table would have been populated but the fact that it is not populated before running the server is causing a DoesNotExist error. Is there a solution to this?

Django - Is it possible to use other value than pk for modelform field?
I have a model form and I post the form via AJAX. One of the fields is a manytomany field and I render it as checkboxes. By default django uses PKs of the models in the queryset that is passed in. Is there a way to use another field of the model as value instead of PK values. (I have PK as integer - for a reason. I also have a UUID field which is not PK. I want to use that one for values.) -
