Django createview m2m not saving

Django-admin start project <name> creates old version django project
I created a directory "DjangoProject1" and in it created django project through the terminal with the line $ django-admin startproject project As I was expected, there were created two things in the directory "project": file "manage.py" and another directory "project". The problem is that in that directory "project" there were: {init, setting, urls, wsgi}.py, but there wasn't file "asgi.py". From there I understood that there was created an old version django project. Again! I checked it one more time in "urls.py" file and I saw this: urlpatterns = [ url(r'^admin/', admin.site.urls), ] instead of this: urlpatterns = [ path('admin/', admin.site.urls), ] So it is definitely an old version of django project. I don't know why this problem occurs, as I installed a new version of django, and I was able to create new version django project, though I don't remember how I was doing that. Can anyone help me to liquidate this problem so that only new version django projects would be created? (PS before new version maybe I installed an old version, and probably in my computer now there are both: new and old versions of Django) -
Django Rest Framwork - Put FileField value into response
in my Django Rest Framwork project, I have the following view: class RegistrationView(APIView): def post(self, request, format=None): data = {} # check if email exists ... # check if username exists ... # at this point, we know everything is ok -> the serializer can do its work serializer = RegistrationSerializer(data = request.data) if serializer.is_valid(): account = serializer.save() data['response'] = 'registered new user' data['id'] = account.id data['email'] = account.email data['username'] = account.username data['profile_pic'] = account.profile_pic <--- HERE the problem occurs!! data['date_joined'] = account.date_joined token = Token.objects.get(user=account) data['token'] = token.key else: data = serializer.errors return Response(data) I tried to put the result of the registration process into data dictionary which is then returned as response to the user. But in the line where I have data['profile_pic'] = account.profile_pic an exception occurs stating this: UnicodeDecodeError: 'utf-8' codec can't decode byte 0x89 in position 0: invalid start byte The profile_pic field of the Account model is a FileField as you can see in the following: class Account(AbstractBaseUser): ... profile_pic = models.FileField(upload_to='Images/',default='Images/None/placeholder.jpg') How can I get the value of the FileField which basically points to the profile picture of the Account. -
Will there be any performance improvement when accessing objects this way in django ORM?

django passing a csv to another function that downloads this csv

Where is this self.add_error adds the error to?

In the documentation, it says that the password here is the field in add_error('field', 'error'). So, is the error being added to the password field? or is it being added to the following part? def __init__(self, user, *args, **kwargs): super().__init__(*args, **kwargs) self.user = user because if I have to access this error in the html template, I would have to do something like this, {% if password_form.password.errors %} and if it means accessing errors from password field, it should mean that the error is added to the password field... but the self.add_error part confuses me -
