django.db.models has no attribute "PublishedManager"
I'm following along in a book and came across an error I can't seem to solve on my own. Im trying to add a model manager so I can search only published blog posts. In my blog app, I first added the custom manager class as shown below: class PublishedManager(models.Manager): def get_queryset(self): return super(PublishedManager, self).get_queryset().filter(status='published') I then added the following lines to my Post model. class Post(models.Model): objects = models.Manager() #default manager published = PublishedManager() #new manager The error I am getting is: AttributeError: module 'django.db.models' has no attribute 'PublishedManager' Any help greatly appreciated, I have struggling trying to figure out what is wrong for quite a while now! -
Is it possible to use the same Django models/views/etc with two different databases?
I have a Django application and I want to host it using 2 databases - one for test data and the other with real data, with the database path defined by the url accessing the site - ie test.mysite.com versus mysite.com. I looked through the Django docs at using multiple databases and routers, but those examples and others use the databases to split up the apps. For example, all data from the Customer model goes in the customer db, and all data from the User model goes in the user db as defined in settings.py. Is there a way to use one django app and configure two databases, with the db selection based on the url? Perhaps the best solution is to set up 2 virtual environments, one for mysite.com, and the other for test.mysite.com, and let apache's virtual hosts be the "router". As the app(s) evolve, I can clone the sites from the master git repo. Thanks for your thoughts! Mark -
Django Query across multiple model relationships
I'm trying to make a query for a set of instances in the ActivityPartsModel filtered by a group. When I try to run the following. I am left with an Attribute Error: "'QuerySet' object has no attribute 'activity'" activities = GroupActivityModel.objects.filter(group=id) parts = ActivityPartModel.objects.filter(activity=activities.activity.all()) print(parts) How would I go about filtering ActivityPartModel with a GroupModel ID/instance class ActivityModel(models.Model): activityName = models.CharField(max_length=100) description = models.CharField(max_length=200) workCenter = models.ForeignKey(Group, on_delete=models.PROTECT) history = HistoricalRecords() class ActivityPartModel(models.Model): activity = models.ForeignKey(ActivityModel, on_delete=models.PROTECT) part = models.ForeignKey(PartModel, on_delete=models.PROTECT) quantity = models.IntegerField(default=1) increment = models.BooleanField(default=False) # TRUE/FALSE used to represent parts ActivityPartModel/produced order = models.IntegerField(blank=False, default=100_000) location = models.TextField(max_length=50, null=True) history = HistoricalRecords() class GroupModel(models.Model): groupName = models.CharField(max_length=50) class GroupActivityModel(models.Model): group = models.ForeignKey(GroupModel, on_delete=models.PROTECT) activity = models.ForeignKey(ActivityModel, on_delete=models.PROTECT) order = models.IntegerField(blank=False, default=100_000) groupName = models.CharField(max_length=50) -
Django: checking is_null in values() queryset
I have this queryset: output = self.filter(parent=task, user=user).values( 'label', 'minutes_allotted', 'days_to_complete', 'pk', number_of_children=Count('children') ) It does the job. But I'm really only using it to check if an object has children (I don't really care about how many it has). Is there a way to use isnull here? I've tried: output = self.filter(parent=task, user=user).values( 'label', 'minutes_allotted', 'days_to_complete', 'pk', 'children__isnull' ) and: output = self.filter(parent=task, user=user).values( 'label', 'minutes_allotted', 'days_to_complete', 'pk', is_not_parent='children_isnull' ) but neither were correct. -

Nginx Bad Request (400) using upstream server in proxy_pass
I am really confused... On IP4 123.456.789.123 I have a django app running. On my local computer I create a simple nginx image with docker: FROM nginx COPY default.conf /etc/nginx/conf.d/default.conf and run it. In default.conf I use: server { listen 80; location /api { proxy_pass http://123.456.789.123; } } This version works just fine. Entering 127.0.0.1/api will lead me to my django app online.. But using: upstream djangpapp { server 123.456.789.123; } server { listen 80; location /api { proxy_pass http://djangpapp; } } will give me a bad request 400. I dont understand why. this: proxy_set_header Host $http_host; does not work, even thou it seem'd to be the solution for some people.. it even gives me a 400 in the otherwise working 1st version. -

Create Django model at runtime for testing purposes
The idea is to be able to write tests for my abstract models, since they cannot be instantiated or mapped to a table on the (test) database. I'm trying to create the table dynamically from a model, ideally enclosed in a with block. To do that, I dynamically create a model that inherits from the abstract model and execute the SQL to create the associated table (on __enter__), and delete the table when I'm done (on __exit__). I've tried several options: This, which fails with the error AttributeError: 'DatabaseCreation' object has no attribute 'sql_create_model'. It appears that sql_create_model is probably from an older version of Django. Doesn't look viable. This, which fails with the error django.db.utils.NotSupportedError: SQLite schema editor cannot be used while foreign key constraint checks are enabled. Make sure to disable them before entering a transaction.atomic() context because SQLite does not support disabling them in the middle of a multi-statement transaction. It actually looks like a valid solution, but fails with SQLite3. As you can see here, the implementation is trying to disable constraint checking, but failing, for some reason. This option appears as if it could be viable if I could figure out why disabling constraints checking … -
How to access data across M2M tables in Django?
What is the 'best practice' way of accessing data across a 1 (or more) many-to-many tables? This is incredibly difficult for me as I am not sure what I shuld be googling/looking up. I have attached a diagram of my data model. I am able to query data for 'C' related ot a user, by utilizing serializers. there has to be a simpler way of doing this (I'm hoping). Doing it with serializers seems incredibly limiting. I'd like to access a user's 'B' and 'C' and transform the object to only have a custom structure and possible unique values. Any direction is much appreciated. Pretty new to Django, so I apologize for this newb type of question. -

Django suggestions / autocomplete - remote API (geocoding, forward address, map)
in my spare time I am learning django. I'm making a site and currently I'm stuck, already for two days. In "search module" I try to parse address input from user and provide suggestions on city/town based on that input. Currently I am using ajax, jquery and selectize plugin in my html template. I know that this is not a long term solution as API key (google maps api key) is open to public and probably not the safest way to transfer lat/long data into backend. The reason that I am using API is that I get latitude and longitude for certain address and I need to get it into backend. I've tried to search on github for correct repo, nevertheless most of them are not up to date with django 3.1. What other solution can be used with django to call ajax? tldr: suggestion/autocomplete based on user query; remote api> reverse lookup address to latitude and longitude> latitude and longitude to backend -

(Django) UpdateView query only working sometimes
I have a school management app that has a feature to drop a student or teacher from a particular course. The problem is it only works with some users and not others. In my urls.py, I have the following: path('profile/<int:pk>/drop_session/<int:pk2>', user_views.DropStudentFromSession.as_view(), name='drop_student_session'), Then in my views.py, this is my CBV for dropping a student: class DropStudentFromSession(UserPassesTestMixin, UpdateView): model = Session template_name = 'users/drop_student_session.html' fields = [] def test_func(self): return True if self.request.user.groups.filter(name='Admin').count() > 0 else False def handle_no_permission(self): return redirect('denied') def form_valid(self, form): course = get_object_or_404(Session, pk=self.kwargs.get('pk2')) user = get_object_or_404(User, pk=self.kwargs.get('pk')) user.student.enrolled_courses.remove(course) user.save() return super().form_valid(form) def get_success_url(self): user = get_object_or_404(User, pk=self.kwargs.get('pk')) messages.success(self.request, 'Student withdrawn from session.') return reverse('user_profile', kwargs={'pk': user.id}) So the in the form_valid method, it grabs the user's PK and the session's PK so it can successfully remove it from the student's enrolled courses. But it seemed to only work with my one test user that has a PK=2, but not the others. What am I missing here? -

I have my ip as 192.168.0.5 where the django server is running i can access 192.168.0.5:8000/admin from my pc (i.e where server is running, same as the ip) but then when i try to access from a pc on lan it says CONNECTION TIMEDOUT on that pc on lan i tried to ping the ip 192.168.0.5, ping working fine Later i found that its the firewall. When I disable the firewall DJango project is accessible in LAN, else not. I havent touched the firewall at all. But in the contrary i have a reactjs app running in development mode. but its accessible on lan, SO what can i do with windows firewall to enable the django accessible on lan
