Why am I getting an smtp authentication with Django on PythonAnywhere
If you go on my webapp. You'll see a reset password option at the bottom of the login form but you need to register an account first and then try resetting your password. If you then type in your email and send, you will get a 500 Error page which I added custom styling to. So there was an error in my app in production, which does not show up in development. Everything worked perfect when I ran the localhost and tried it. I hosted my Django app on pythonanywhere so I went on my profile on PythonAnywhere and went to my log files and found this: smtplib.SMTPAuthenticationError: (535, b'5.7.8 Username and Password not accepted.

Changing ordering of model in the admin views
I have a User model in Django, in which I defined class Meta with ordering. It's defined like this: class Meta: verbose_name = _('user') verbose_name_plural = _('users') ordering = ('-speedy_net_site_profile__last_visit',) swappable = 'AUTH_USER_MODEL' But, I have two apps - Speedy Net and Speedy Match, and in Speedy Match I want a different order ( ordering = ('-speedy_match_site_profile__last_visit',) ). How can I do this? -
What is the appropriate way to use a ModelForm field as an argument to upload_to?
I have a ModelForm, where two of the fields are lastname and firstname. As several files are being uploaded by many different people, I would like to group the files into a directory based on their names. I've been trying to use a custom formatted string to do this, but so far I'm getting an error that there are not enough arguments for format string, and I am wondering if it as something to do with the form not being saved yet. My attempt to generate a filename based on form fields is: def filename_path(instance, filename): return os.path.join('applicant_documents/%s_%s/%s' % instance.last_name, instance.first_name, filename) and the field from my model is defined as: documents = models.FileField(upload_to=filename_path) Am I doing something wrong, or is this not possible? -

Django Web API Call Server Pagination Issue
So I am trying to make a call on an API endpoint that could return results to a template in the range of 0 - 450,000 items. The API has a search endpoint as so, https://api.rawg.io/api/games?search=rimworld, and since this only results in 12 games, there's only one page and my function works as expected. When there are more than 20 results, the max allowed per page for this API (RAWG.IO API). This results in the JSON having a "next" key with something like this, https://api.rawg.io/api/games?page=2&search=grand. I cannot for the life of me figure out how to get the data from any of the pages past page 1. I have resorted to using JS to write this function, but I much rather use a Django view. I run into the same issues, where I can't collect past the first page. Whenever there is more than one page, my memory usage skyrockets, the page doesn't show any results, and the loading icon runs forever. There's either a memory leak or the resulting dict that I'm storing these in to display is just that huge. Whether someone can give me some insight in either JS or Python, I'm sure I can figure out … -

Could not resolve URL for hyperlinked relationship using view name "book-detail"
Previously I was using ModelSerializer and there were no error. When I replaced it with HyperlinkedModelSerializer this error was thrown Could not resolve URL for hyperlinked relationship using view name "book detail". You may have failed to include the related model in your API, or incorrectly configured the `lookup_field` attribute on this field. this is serializers.py file: class BookSerializer(serializers.HyperlinkedModelSerializer): class Meta: model = Book fields = ['id', 'url', 'title', 'subtitle', 'isbn'] model.py class Book(models.Model): title = models.CharField(max_length=250) subtitle = models.CharField(max_length=250) author = models.CharField(max_length=100) isbn = models.CharField(max_length=13) def __str__(self): return self.title views.py class BookListView(viewsets.ModelViewSet): queryset = Book.objects.all() serializer_class = BookSerializer and urls.py router = routers.DefaultRouter() router.register('books', BookListView) app_name = "books" urlpatterns = [ path('', include(router.urls)), ] view name book-detail doesn't exist in my views, probably Django created it automatically and I don't know where to find and debug it?

Django Oscar version updated automatically
I am learning about Django Oscar. I was following a tutorial yesterday that is using Django Oscar version 1.6. I followed all the instructions in the tutorial. It was working fine yesterday. Now, when I ran my project today using python manage.py runserver, I got the error about using get_core_apps which has been removed in Django Oscar 2. I ran pip freeze to see the version of Django Oscar installed on my device and it said 2.0.2. Was it updated automatically? I did not make any changes to the project since working on it yesterday.
