I sorted out the city name using simple icontains. similarly I want to sort out for ndays. previous ndays data needs to be shown. example: suppose today is 2019-08-29, on providing ndays to be 6, weather data of particular city has to be provided from 2019-08-24 to 2019-08-26. views.py class weatherDetail(APIView): def get_object(self, city_name, ndays): try: x = weatherdata.objects.filter(city_name__icontains=city_name) now = datetime.datetime.now() fromdate = now - timedelta(days=ndays) y = return x except Snippet.DoesNotExist: raise Http404 def get(self,*args,**kwargs): city_name = kwargs['city_name'] snippet = self.get_object(city_name,ndays) serializer = weatherdataserializer(snippet,many =True) return Response(serializer.data) models.py class weatherdata(models.Model): city_name = models.CharField(max_length = 80) city_id = models.IntegerField(default=0) latitude = models.FloatField(null=True , blank=True) longitude = models.FloatField(null=True , blank=True) dt_txt = models.DateTimeField() temp = models.FloatField(null = False) temp_min = models.FloatField(null = False) temp_max = models.FloatField(null = False) pressure = models.FloatField(null = False) sea_level = models.FloatField(null = False) grnd_level = models.FloatField(null = False) humidity = models.FloatField(null = False) main = models.CharField(max_length=200) description = models.CharField(max_length=30) clouds = models.IntegerField(null=False) wind_speed = models.FloatField(null = False) wind_degree = models.FloatField(null = False) urls.py urlpatterns = [ path('admin/', admin.site.urls), … -
Django: unique_together for foreign field
For next two models: class Foo(models.Model): parent = models.ForeignKey(Parent) name = models.CharField() class Bar(models.Model): foreign = models.ForeignKey(Foo) value = models.CharField(max_length=20) I need to have unique_together constraint for Bar model: class Meta: unique_together = ('value', 'foreign__parent') Which is impossible in Django. But is it possible to achieve this on database level (Postgresql) with some contraint or model level validation to omit possible case (lock table?) when simultaneously same value may be saved to different Bar instances? Django 2.2.4 No ModelForm or default validate_unique() -
What's the best way to handle service accounts in django?
I have a Django / REST framework application that needs to recieve logs from remote workers and store them as objects in the database so that they can be provided to users through the web interface. I am using the standard DRF token authentication and I was thinking the best way to do this would be to create a service account with permissions restricted to PUT on the log view, so that the workers could use this to send logs back to the django app. Is there a way I can have an account with token authentication but without password login? Is there any best practices / reading material around service accounts, or is there a better way of achieving this goal? I can't seem to find anything relevant. Is there an easy way of generating such an account on initial setup without having to use the admin interface so that it is ready to go on install? Thanks in advance -

How to implement 'follow' functionality on a blog author
I have a blog app that works pretty well. However I want to expand its functionality to include an option for users to follow authors. I created a class FeedListView has a get_queryset function but i dont know how to use this to return the authors the logined in user follows. my FeedListView looks like this: class FeedListView(ListView): model = Post template_name = 'blog/feed_posts.html' # <app>/<model>_<viewtype>.html context_object_name = 'posts' paginate_by = 6 def get_queryset(self): queryset = Post.objects.filter(author__followers=user) return queryset # self.user = self.get_object() # return Post.objects.filter(author__followers=user) The model (User) like this: class Profile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) image = models.ImageField(default='default.jpg', upload_to='profile_pics') follows = models.ManyToManyField('self', related_name='followed_by', symmetrical=False) def __str__(self): return f'{self.user.username} Profile' the url.py is: path('feed/', FeedListView.as_view(), name='feed_posts'), If i can get it to the state where when i navigate to the url the posts only by the followed users are displayed I would be overjoyed.

Linode/Django Can't see site when I runserver at ip:8000
I had started a fresh linode running ubuntu 19.04 and the first time I used the directions at: https://www.rosehosting.com/blog/how-to-install-mezzanine-cms-on-ubuntu-18-04/ To install Mezzanine CMS it worked just fine, I could run the runserver command and see the django website. Eventually it started giving me a problem after trying 50 ways to deploy the site using apache and mod_wsgi. I gave up and rebuilt the server and then still couldn't see the new install at the IP when I ran run server. I figured maybe it was because I accidentally installed some things using "python" and others with "python3" so I rebuilt the server. This third time I followed the direction perfectly, the only difference is I didn't install a mysql server just kept the default SQLlite server and created a DB and Django Superuser. I have added my ip as a host in settings.py and local_settings.py I have already ran makemigrations and migrate I did check to see if maybe the IP had changed when I rebuilt, it hadn't My local environment on my laptop works fine, just not the linode Any suggestions on anything I'm missing? -

Is it possible to set the enctype="multipart/form-data" for a form in the backend?

Editing dynamic choice fields in Django
I have a standard Django blog with a Post model, only on the model I have added a ManyToManyField for approvers, the idea being that the backend passes the post to 2 or more approvers to confirm the content before it is published. class Post(models.Model): author = models.ForeignKey( get_user_model(), null=True, on_delete=models.SET_NULL) title = models.CharField(max_length=30) content = models.CharField(max_length=30) approvers = models.ManyToManyField(Approvers) I will probably learn towards something like django-fsm to create a finite state machine for the Post model to govern whether it is draft/in approval/published, but I would like to be able to change the approvers field so that the number and order of approvers (users) can be changed dynamically by the user. What is the best way to do this? I thought I could try and change the approvers field to a JSONField so that users can add / delete / change the order of approvers and then handle the interpretation in the frontend and write some function to interface with django-fsm, but this feels like it conflates things too much. Am I missing a simpler route? -
