Django won't connect to MySQL
After spending hours finding the correct connectors to hook up MySQL with Django, I can't create a super user. error: django.db.utils.OperationalError: (2059, "Authentication plugin 'caching_sha2_password' cannot be loaded: The specified module could not be found.\r\n") I tried setting environment variables, settings.configure() which said the settings were already configured. db info is all correctly entered in settings.py. Pycharm is able to connect to the db though, this is inside my django project and the db title in pycharm says Django default. I don't know if this means my Django project is connected to it but I just can't create a super user or that the pycharm connection is not related. DATABASES = { 'default': { 'ENGINE': 'django.db.backends.mysql', 'NAME': 'dbname', 'USER': 'root', 'PASSWORD': '', 'HOST': 'localhost', 'PORT': 3306 } } When i try django-admin dbshell I get this error: django.core.exceptions.ImproperlyConfigured: Requested setting DATABASES, but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings. Both solutions provided in the error have had no positive result. My last question got marked as duplicate although the solution didn't work, the question was also different in some ways.. anyway below is what happened when I tried using … -
Django Channels producer consumer problem not working properly
I wrote django channels code to send api data from two different sources asynchronously. The different sources takes few seconds to 1 minute to compute and send back the data. I managed to call them asynchronously using asyncio event loop. But the issue is that they are not sending the resposne back asynchronously. The code just waits for the all the data to arrive and sends everything at the same time. Channels Code: class SearchHotelConsumer(AsyncWebsocketConsumer): def __init__(self, *args, **kwargs): super().__init__(*args, **kwargs) self.source1 = Source1() self.source2 = Source2() async def connect(self): await self.accept() def disconnect(self, close_code): pass async def _source1_handler(self, request, queue): source1_response = await self.source1.async_post(request) await queue.put(source1_response.data) async def _source2_handler(self, request, queue): source2_response = await self.source2.async_post(request) await queue.put(source2_response.data) async def _send_msg(self, queue): while True: message = await queue.get() if message is None: break print('got the message') self.send(text_data=json.dumps({ 'message': message }, cls=DjangoJSONEncoder)) queue.task_done() def receive(self, text_data): text_data_json = json.loads(text_data) message = text_data_json['message'] request = HttpRequest() request.method = 'POST' request.session = self.scope["session"] request = Request(request) for key, val in message.items(): request.data[key] = val queue = asyncio.Queue() sender = asyncio.ensure_future(self._send_msg(queue)) await self._source1_handler(request, queue) await self._source2_handler(request, queue) await queue.join() sender.cancel() How can I make the message sending part truly asynchronous? -
Is it good practice to call model methods inside other model methods in Django?
I'm trying to write my code as "Pythonic" as possible in Django. Consider the following model: class MyRequest(models.Model): ... def get_prices(self): ... def set_costs(self): ... def get_details(self): self.set_costs() x = self.get_prices() return x % 10 Is it good practice to call model methods inside each other? -
Using angular js post to django back end yields a 414 error

I have been working on trying to fix the problem for the last few days but cant seem to figure things out. When I try to start up the development server for Django I get the following error: raise ImproperlyConfigured(msg.format(name-self.urlconf_name)) Django.core.exceptions.ImproperlyConfigured: The included URLconf '' does not appear to have any patterns in it. If you see valid patterns in the file then the issue is probably caused by a circular import. Any help would be greatly appreciated. I am trying to set the music app up so that when queried will send an index file. website.urls from django.contrib import admin from django.urls import include, path urlpatterns = [ path('admin/', admin.site.urls), path('music/', include('music.urls')) music.urls from django.urls import path from . import views path('', views.index, name="index") music.views from django.http import HttpResponse def index(request): return HttpResponse("<h1> This is my Home Page </h1>") -
Django - Room model needs to have a selection of many room types. One room must have at least one room type from the predefined selection
One property can have one or many rooms. One room must belong to one property. The question is at the end. I start by creating the Room Model class Room(models.Model): property = models.ForeignKey(Property) name = models.CharField(max_length=250) description = models.TextField(max_length=800) image = models.ImageField(upload_to='room_images/', blank=False) bar_rate = models.IntegerField(default=0, blank=False) max_occupancy = models.IntegerField(default=1, blank=False) extra_beds = models.IntegerField(default=0, blank=True) price_per_exra_bed = models.IntegerField(default=0, blank=True) is_breakfast_included = models.BooleanField(default=False) room_type_quantity = models.IntegerField(default=0, blank=False) ROOM_TYPES = ( ('SGL', 'Single'), ('TWN', 'Twin'), ('DBL', 'Double'), ('TRPL', 'Triple'), ('STND', 'Standard'), ('DLX', 'Deluxe'), ('EXET', 'Executive'), ('SPR', 'Superior'), ('JS', 'Junior Suite'), ('ONEBDR', 'One Bedroom'), ('TWOBDR', 'Two Bedroom'), ('THREEBDR', 'Three Bedroom'), ('FOURBDR', 'Four Bedroom'), ('FIVEBDR', 'Five Bedroom'), ('SIXBDR', 'Six Bedroom'), ('SEVENBDR', 'Seven Bedroom'), ) room_type = models.CharField(max_length=1, choices=ROOM_TYPES, default="STND") def __str__(self): return self.name I create a new form to allow the user to fill out the form. Inside forms.py class RoomForm(forms.ModelForm): class Meta: model = Room exclude = ("property",) As you can see above I exclude the property model, I don’t need to add the property info into the RoomForm. In views.py I have modified the property_add_room function to save the room into the database: @login_required(login_url='/property/sign-in/') def property_add_room(request): form = RoomForm() if request.method == "POST": form = RoomForm(request.POST, request.FILES) if form.is_valid(): room = form.save(commit=False) …
