Django: Changing project folder / settings structure
I am currently trying to change from the default Django structure to that one. I now copied all the files in the new folders, but when running python manage.py runserver --settings=settings.local it shows the following in my terminal: Traceback (most recent call last): File "manage.py", line 16, in <module> execute_from_command_line(sys.argv) File "/Users/Marc/.local/share/virtualenvs/lumis-vJ5Odiz7/lib/python3.6/site-packages/django/core/management/__init__.py", line 371, in execute_from_command_line utility.execute() File "/Users/Marc/.local/share/virtualenvs/lumis-vJ5Odiz7/lib/python3.6/site-packages/django/core/management/__init__.py", line 317, in execute settings.INSTALLED_APPS File "/Users/Marc/.local/share/virtualenvs/lumis-vJ5Odiz7/lib/python3.6/site-packages/django/conf/__init__.py", line 56, in __getattr__ self._setup(name) File "/Users/Marc/.local/share/virtualenvs/lumis-vJ5Odiz7/lib/python3.6/site-packages/django/conf/__init__.py", line 43, in _setup self._wrapped = Settings(settings_module) File "/Users/Marc/.local/share/virtualenvs/lumis-vJ5Odiz7/lib/python3.6/site-packages/django/conf/__init__.py", line 106, in __init__ mod = importlib.import_module(self.SETTINGS_MODULE) File "/Users/Marc/.local/share/virtualenvs/lumis-vJ5Odiz7/lib/python3.6/importlib/__init__.py", line 126, in import_module return _bootstrap._gcd_import(name[level:], package, level) File "<frozen importlib._bootstrap>", line 994, in _gcd_import File "<frozen importlib._bootstrap>", line 971, in _find_and_load File "<frozen importlib._bootstrap>", line 941, in _find_and_load_unlocked File "<frozen importlib._bootstrap>", line 219, in _call_with_frames_removed File "<frozen importlib._bootstrap>", line 994, in _gcd_import File "<frozen importlib._bootstrap>", line 971, in _find_and_load File "<frozen importlib._bootstrap>", line 953, in _find_and_load_unlocked ModuleNotFoundError: No module named 'settings' Can anyone see what I am doing wrong? -
Django get most recent value AND aggregate values
I have a model which I want to get both the most recent values out of, meaning the values in the most recently added item, and an aggregated value over a period of time. I can get the answers in separate QuerySets and then unite them in Python but I feel like there should be a better ORM approach to this. Anybody know how it can be done? Simplified example: Class Rating(models.Model): movie = models.ForeignKey(Movie) rating = models.IntegerField(blank=True, null=True) timestamp = models.DateTimeField(auto_now_add=True) I wish to get the avg rating in the past month and the most recent rating per movie. Current approach: recent_rating = Rating.objects.order_by('movie_id','-timestamp').distinct('movie') monthly_ratings = Rating.objects.filter(timestamp__gte=datetime.datetime.now() - datetime.timedelta(days=30)).values('movie').annotate(month_rating=Avg('rating')) And then I need to somehow join them on the movie id. Thank you! -
Django generating spreadsheet with right extension

Django - URL with www is not safe
I have website as bukimlan.com. We set default site as shown https://bukimlan.com. There is no problem with this url. We have SSL and secure. But if user comes with https://www.bukimlan.com URL, there is a not safe error in address line. And in mobile, google says your connection is not private with www url. Google indexed some pages with www, so we need to solve this problem. Thanks for your replies. -
Filtering reverse Django relationships using same kwargs for different instances of same model
I'm relatively new to Django and I was trying to build a chat server from ground up using Django 2.0.5. I just made the following models today. class DateTimeModel(models.Model): date_created = models.DateTimeField(auto_now_add=True) date_modified = models.DateTimeField(auto_now=True) class Meta: abstract = True class Room(DateTimeModel): id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False) def __str__(self): return str(self.id) class RoomMember(DateTimeModel): room = models.ForeignKey(Room, on_delete=models.PROTECT, related_name='members') user = models.ForeignKey(User, on_delete=models.PROTECT) def __str__(self): return 'member "{}" in room "{}"'.format(self.user, self.room) class Message(DateTimeModel): sender = models.ForeignKey(RoomMember, on_delete=models.PROTECT) text = models.TextField() def __str__(self): return '"{}" sent by "{}"'.format(self.text, self.sender) Now I want to be able to run a query for a room given that I have a list of users. I tried the Q() objects from Django docs in the following way Room.objects.filter(Q(members__user=foo) & Q(members__user=bar)) but this yielded and empty QuerySet for me. Interestingly, if I search for Room.objects.filter(Q(members__user=foo)) only, then I get a QuerySet of all Rooms that contain the certain user foo. But this filtering is not specific enough for my needs. So I assume that this is not the right way to do it. Could anyone please point me to the right resource or suggest another approach if there is one? I'm using SQLite if that helps in … -
Best approach to update django project, track updates
I have a Django project, already hosted. the project contains lots of functionalities. Sometimes, when I update a part of the project, I don't remember where these updates might affect. Page 1 line 1: if obj.love_basket: line 2: up.fan = True # as well line 3: up.save() After months, I want to remove fan attribute and replace it with is_fan Page 2 line 4: class UserProfile: line 5: # fan = models.BooleanField() line 6: is_fan = models.BooleanField() This change will give an error in the future when a user hits line 2 This is just an example. How will I know where these changes may affect? -
How to set Model property, toggle a boolean in Django query?
Is it possible in my Detail view below, to set the boolean within a model to be false ? I looked through the django documentation (queryset) for something like a .set() method for this, it seems to exist but not applicable to this particular case. How can I toggle the unread boolean in my Models.py, through my view ? Also, what am I misunderstanding here and what is the better/appropriate way to do this ? Models.py: class Message(models.Model): recipient = models.ForeignKey(CustomUser, on_delete = models.CASCADE,related_name = 'recipient',null = True) sender = models.ManyToManyField(CustomUser,related_name = 'messages') date = models.DateTimeField(auto_now_add=True, blank=True) subject = models.CharField(max_length = 1000, blank = True) message = models.TextField(blank=True, null=True) unread = models.BooleanField(default = True) Views.py : ### Message detail class class MessageInboxDetail(DetailView): ''' This view lets the user view the details of a message created ''' context_object_name = 'message_detail' model = Message template_name = "myInbox/message_detail.html" def get_context_data(self, **kwargs): context = super(MessageInboxDetail, self).get_context_data(**kwargs) context.update({ 'message_detail': Message.unread.set(False) }) # Message(unread=True/False) return context -

Use passed parameter as a value in query string in django
Is it possible to use a passed parameter as a value in a django query string? So, let's pretend I want to search for specific terms (in term_list) in different fields, like username, display_name or name. Instead of doing this multiple times: q1_username = Q(username__icontains=term_list[0]) q1_email = Q(email__icontains=term_list[0]) q2_username = Q(display_name__icontains=term_list[0]) q2_email = Q(e_mail__icontains=term_list[0]) q3_username = Q(name__icontains=term_list[0]) q3_email = Q(emailaddress__icontains=term_list[0]) I want to be able to do this in a more generic way for different cases: q1_username = "display_name" q1_email = "emailaddress" q1 = build_query(term_list, q1_username, q1_email) def build_query(term_list, passed_username, passed_email): q_username = Q(insert_passed_username_here__icontains=term_list[0]) q_email = Q(insert_passed_email_here__icontains=term_list[0]) # ... return query If I try it like that, I get, not surprisingly, the following error message: Cannot resolve keyword 'insert_passed_username_here' into field. How can I use the passed_username and passed_email to replace the insert_passed_username_here and insert_passed_email_here in the function? -

Django REST Framework - Social Authentication (Facebook, Twitter, etc.)
I'm building REST APIs for a platform where we have iOS, Android and Web apps as clients. Users can register normally via the Django APIs, so authenticate using their credentials or they can sign in to their Facebook or Twitter account using OAuth. I started using django-rest-framework-social-oauth2 to speed up the development of the social login part. The part that I don't understand is related to the URL callback (or URL redirect) pointing back to the server-side Django app. What URL callback should I provide? Is there already an implemented view out-of-the-box from django-rest-framework-social-oauth2? Also, is there a better package available for DRF to be used for the authentication of big projects? -

Django - fetching data from the different table to be shown in admin, getting the error 'NoneType' object has no attribute 'user'
I am beginner for the Django. I am trying to make the admin page in which I want to show the columns(user) from the table(BillingProfile) which is the foreign key to the Order Table. I have created the order model as shown below. Order Model class Order(models.Model): billing_profile = models.ForeignKey(BillingProfile, null=True, blank=True) order_id = models.CharField(max_length=120, blank=True) # AB31DE3 shipping_address = models.ForeignKey(Address, related_name="shipping_address",null=True, blank=True) billing_address = models.ForeignKey(Address, related_name="billing_address", null=True, blank=True) cart = models.ForeignKey(Cart) def __str__(self): return self.order_id The BillingProfile model is as shown below. BillingProfile Model class BillingProfile(models.Model): user = models.OneToOneField(User, null=True, blank=True) email = models.EmailField() active = models.BooleanField(default=True) def __str__(self): return self.email And the Code for the Admin Page is as below. admin.py class OrderAdmin(admin.ModelAdmin): list_display = ['__str__', 'billing_profile','get_user'] class Meta: model = Order def get_user(self, obj): return obj.billing_profile.user admin.site.register(Order,OrderAdmin) When I am trying to get the user of a specific Billing profile then I am getting the error of 'NoneType' object has no attribute user. this might be due to the fact that few rows of Order table is empty. Can't I show the users of the remaining Rows? -
Django template is not changed after update (possible cache)
I have a problem with Django. Possibly with it's cache. Version 1.11 I use template in urlpatterns like : urlpatterns = [ url(r'^service_preview/', include(serviceprev_urls, namespace = 'service_preview')), url(r'^service_preview/',TemplateView.as_view(template_name='service_preview.html')), ] After a lot of updates, applied to my template, the cnahges stop appearing in user's browser. I have actual template in my templates folder and some previous version when preview source code in browser. If i rename template (this should raise error because template is absent), i still have that previous template in browser source. Browser page refreshing, clear browser cache etc does not help. There are no duplicates of this page in my template folder. When i use another template, all ok. Possibly, problem is in django cache. I don't know how to force clear cache, maybe it would be a solution. I put this at app setting file, but it doesn't helps. CACHES = {'default': {'BACKEND': 'django.core.cache.backends.dummy.DummyCache',}} Please, help me with solving problem -

Django authentication with basic auth with LDAP support and no User model
This is my first Django project so please bear with me. I am creating a pure DRF project. My requirement is that the user will call the REST APIs while sending the user creds in basic auth format which I need to validate against a LDAP server. Also, each API with have the credentials sent and so I do not need to store the credentials at my end (in the default USER model) I was aiming to use : REST_FRAMEWORK = { 'DEFAULT_AUTHENTICATION_CLASSES': ( 'rest_framework.authentication.BasicAuthentication', ) } and INSTALLED_APPS = [ 'django.contrib.auth', } to be able to read the basic auth creds and then hoping to hook in: AUTHENTICATION_BACKENDS = [ 'django_auth_ldap.backend.LDAPBackend', ] to authenticate the user at LDAP server. questions: -- is there any better approach ? -- since I am only passing on the credentials to LDAP server to know if the creds are valid, I do not need the USER table in the database. I need it only for object modeling. How can I acheive this? would a Proxy model help? Can we have an abstract model as the AUTH_USER_MODEL? or using a remote user authentication backend a better option? -
