Python Django-channels create one instance of class for each room
I am using django-channels to make a small webgame. So far, I've been able to connect the client to the server and have different consumers in the same room/lobby (same as in the channels tutorial, where a room is defined by it's url) sending data to each other. The problem I'm having is that currently, every time any consumer connects to the server, a new game instance is created. However what I would like to do instead is have one game instance per room, so the moment a room is created, a game instance is started. Where can I initialise the game in such a way that the consumer class in that lobby also has access to it? -
Django template table with missing data for some columns
Okay, I give up. I searched through and through and lost something that looked like an answer, so I have to ask. Say, data for a regional power grid and each power plant has a production plan for a day, all of them go as list of dicts with a plan for every hour. Data also include a power consumption forecast, which naturally only has data for hours in the future. [ {'station_id':'Grid','plan_code':1000,'plan':{1:300,2:500,3:250,...,23:519,24:200}} {'station_id':'Plant1','plan_code':1001,'plan':{1:100,2:224,3:150,...,23:239,24:100}} {'station_id':'Plant2','plan_code':724,'plan':{1:200,2:226,3:100,...,23:240,24:100}} #every hour contains value {'station_id':'Consumption','plan_code':2003,'plan':{21:1600,22:1710,23:1250,24:1100}} #only few hours have data ] What I'm trying to generate with Django template is a table of power grid production, consumption and balance values: <table> <thead> <tr style="font-size: small"> <th>Plan for</th> <th>Type</th> <th>01</th> <th>02</th> <th>03</th> ... <th>22</th> <th>23</th> <th>24</th> </tr> </thead> <tbody> {% for plan in plans %} <tr style="font-size: small"> <td>{{ plan.station_id }}</td> <td>{{ plan.plan_code }}</td> {% for hour,val in plan.plan %} <td>{{ val }}</td> {%endfor%} </tr> {% endfor %} </tbody> </table> The questions are: How dow I determine order in which plans are displayed? How do I fill a row with consumption plan with empty cells if no value is provided for that hour? Please, help a beginner here. -
How to annotate a Django QuerySet with a Point?
Lets say I have a model A that has fields lat(FloatField) and lon(FloatField). I want to annotate the QuerySet using a point: A.objects.annotate(point = Value(Point('lat', 'lon'), output_field=PointField())) I keep on getting TypeError('Invalid parameters given for Point initialization.') For some reason Django is not recognizing the fields and instead is passing them as strings (I think). How do I accomplish this? Thanks -
How to mock a function in a file?
I have a function in a file generate_new.py: def generate_new(): return ''.join(["{}".format(randint(0, 9)) for num in range(0, 4)]) Iam using the following decorator to mock the function. but it dosn't work! class TestPhoneVerify(APITestCase): def generate_token(): foo = ["11111", "22222"] return random.choice(foo) @mock.patch('lenmo.phoneverify.utils.generate_new.generate_new', side_effect=generate_token) def x(self, token): /do sth but "generate_token" function output doesn't replace "generate_new" in generate_new file! -
Why Django doesn't wrap [] or SELECT to ARRAY in case of using Array field?
For example I have such query as: Chat.objects.filter(users__contains=[user.pk]).filter(users__contained_by=mentors.values_list('pk', flat=True)) This turns to such query: SELECT "chat_chat"."created_at", "chat_chat"."updated_at", "chat_chat"."id", "chat_chat"."users" FROM "chat_chat" WHERE ("chat_chat"."users" @> [1]::integer[] AND "chat_chat"."users" <@ (SELECT V0."id" FROM "users_user" V0 INNER JOIN "users_userrequest_mentors" V1 ON (V0."id" = V1."user_id") WHERE V1."userrequest_id" IN (SELECT U0."id" FROM "users_userrequest" U0 WHERE U0."user_id" = 1))::integer[]) If I run this query , I'll face the problem of casting. cannot cast integer to integer[] But the documentation of Postgres says that arrays should be used as ARRAY[1,2,...,4] So I've wrapped [1] and (SELECT ...) to ARRAY like SELECT "chat_chat"."created_at", "chat_chat"."updated_at", "chat_chat"."id", "chat_chat"."users" FROM "chat_chat" WHERE ("chat_chat"."users" @> ARRAY[1]::integer[] AND "chat_chat"."users" <@ ARRAY(SELECT V0."id" FROM "users_user" V0 INNER JOIN "users_userrequest_mentors" V1 ON (V0."id" = V1."user_id") WHERE V1."userrequest_id" IN (SELECT U0."id" FROM "users_userrequest" U0 WHERE U0."user_id" = 1))::integer[]) And everything works fine. I'm just curious why Django (or psycopg2) skip this wrapping. Is there any special meaning for such behavior ? -
DRF Post to ViewSet without writing into Model
I've always written data into database when posting via Django Rest Framework endpoints. This time I would like to process received data and send it somewhere else without writing into DB. I switched from ModelViewSet to ViewSet, I can issue GET request OK but receiving Bad Request 400 when I curl or POST via DRF URL. Here's a working minimal code (removed need for authentication etc): urls.py from django.urls import path, include from .views import ContactView from rest_framework import routers router = routers.DefaultRouter() router.register('message', ContactView, basename='message') urlpatterns = [ path('', include(router.urls)), ] serializers.py from rest_framework import serializers class ContactSerializer(serializers.Serializer): text = serializers.CharField(max_length=250) views.py from rest_framework.response import Response from .serializers import ContactSerializer from rest_framework import viewsets class ContactView(viewsets.ViewSet): def list(self, request): return Response('Got it') def create(self, request): serializer = ContactSerializer(data=request.data) if serializer.is_valid(): return Response(serializer.data) else: return Response('Invalid') Would greatly appreciate your suggestions. -
Django Do Not Use One Model Of Third Party App
In the app django-cookie-consent, I do not want to use the following table: https://github.com/bmihelac/django-cookie-consent/blob/master/cookie_consent/models.py#L105-L119 When a user accepts/declines a cookie, a log entry in the database is created. But users could abuse this and spam click the buttons and fill up the database. Or I need a way to create a setting for settings.py to disable/enable the logging functionality completely without breaking the app since admin.py and util.py of that app have code associated with this model. How would you go about doing something like this? -

How to register/login a user with django oauth toolkit
I've been trying to implement oauth2 authentication system to my register/login system. The problem I'm facing is django-oauth-toolkit docs don't explain how to register a user, like what I should do with my register/login APIView. I know that I should get client_id and client_secret after creating a user and use them while logging in but don't know how to implement that logic to my views. So there is my code: views.py class UserRegisterAPIView(generics.CreateAPIView): queryset = CustomUser.objects.all() serializer_class = UserCreateSerializer class UserLoginAPIView(APIView): serializer_class = UserLoginSerializer def post(self, request, *args, **kwargs): data = request.data serializer = UserLoginSerializer if serializer.is_valid(raise_exception=True): new_data = serializer.data return Response(new_data, status=HTTP_200_OK) return Response(serializer.errors, HTTP_400_BAD_REQUEST) -
SHH port forwarding with Nginx and Gunicorn web server not working
I want to host a Django web app that runs on my local workstation with no static public IP address. I've got a Linux server with a public IP address, which I want to use as a proxy to my web app so as to make it available to the outside world. I've setup Nginx with Gunicorn locally, and it works just fine when tested locally.

How to execute a javascript function above two columns and return as a third column?

How to structure User - Team - Project model Django (ManyToMany)
I'm hoping someone can give me a push in the right direction, at least conceptually. What I'm trying to achieve; a model where: You have users, teams and projects; Teams should always be linked to a project (i.e. they exist "in" projects) Users can be linked to a project without being a team; Users can be in multiple teams and projects I've read something about Models Managers before, should I use these? Something else I'm struggling with is that users can/should be linked to projects directly or though a team, will this cause problems? below some snippets from the models.py file class User(models.Model): email = models.EmailField( verbose_name='email address', max_length=255, unique=True ) first_name = models.CharField(max_length=100) last_name = models.CharField(max_length=100) class Workstream(models.Model): name = models.CharField(max_length=100) project = models.ForeignKey(Project, on_delete=models.CASCADE) members = models.ManyToManyField(User) #Like this? class Project(models.Model): name = models.CharField(max_length=100) members = models.ManyToManyField(User) #Like this?

Why is my ManyToManyField in Django returning only one value?
In my Django project, I have a class with a ManyToManyField: class ContestCategory(models.Model): name = models.CharField(max_length=70, blank=False, null=False) judges = models.ManyToManyField('users.CustomUser', null=True) I can see after migrating that everything worked fine and the table is created. I made a form to change the judges like this: class JudgesForm(forms.ModelForm): class Meta: model = ContestCategory fields = ['judges'] def __init__(self, *args, **kwargs): super(JudgesForm, self).__init__(*args, **kwargs) In my view, the form appears and correctly displays all the CustomUser objects there are, and shows no error when saving. However, in my post method, when I do this: class SubmissionCategoriesDetailView(LoginRequiredMixin, DetailView): model = ContestCategory template_name = 'reportes/detail_submission_categories.html' form_class = JudgesForm def post(self, request, *args, **kwargs):# 1711 5656 2230400 7616 pk_category = kwargs.get('pk') judges = request.POST.get('judges') logging.info(str(judges)) return HttpResponseRedirect(reverse('reportes:submission_categories')) I get in the logs that 'judges' returns the correct Id of my CustomUser but only if I have just one CustomUser selected. Whenever I choose more than one, it only gives me in 'judges' the Id of the last one that was chosen, not of all of them. Why is this happening? Should I use a different widget than the automatic one or is there something missing from the models? Any help would be appreciated. -

Why isn't one function loading my model into a database even though it works for a different model?
I am trying to load 500 instances of two different models into my Django database. I wrote a migration to accomplish this, which runs a function for each model that loads the required instances into the database. The two functions are exactly the same except for the type of model it creates. However, for some reason, only the first function (loadSongs) properly loads the functions into the database correctly. The second function (loadAlbums) immediately yeilds a TypeError and says that an object of "NoneType" is not callable. I've already made sure that the array I pass into bulk_create is not empty, and every instance of the model seems to be saving into the array properly. Does anyone know what the issue might be? Here are the two functions I am calling: from bs4 import BeautifulSoup import numpy as np from ..models import Song,Album from django.db import migrations import requests from time import sleep from random import randint # Create function to load song data into table def loadSongs(apps, schema_editor): # Initialize counter to iterate through site pages, initialize album rankings, create model, then scrape pages one by one links = np.arange(1,11,1) rank = 500 songList = [] for link in … -
