How to use Valentina or DBeaver to load/import a .sql dump file (from the development version of a website) to the local version on my computer?
I have a .sql file which is a dump of the data coming from the development version of a website. I want to use that data in the local version of the website's Django backend running on my desktop I can see it at localhost:8000 but in the docker-compose.yml file the db is located at port 5432. What are the steps I need to do using Valentina or DBeaver to load in the data such that that data is what I see in Valentina or DBeaver ? I've already tried loading the dump through right-clicking the name of the database then choosing load dump from the options but I still don't see any data in the database tables. -
Django Table - Single Row if Item is unique
Is there a way to get all the amounts on a single row in HTML if "category name" is unique? According to my code, "category name" is no longer unique because it is being annotated by month.

Will I need a consumers.py, asgi,py and routing.py using Tradier's websocket API?
So I'm trying to stream market data via the tradier API with websockets. Here are 2 links to the docs: https://documentation.tradier.com/brokerage-api/streaming/websocket-streaming https://documentation.tradier.com/brokerage-api/streaming/wss-market-websocket I'm not too familiar with websockets, so I'm wondering if I need to use django channels and add a consumers.py, asgi.py, and routing.py to stream this market data live to a front end? If the answer is yes, what would I need to add in each of these files? I've tried just having a consumers.py and having the streaming endpoint in urls.py consumers.py: import json import logging import websockets from channels.generic.websocket import WebsocketConsumer from .tradingAPI.tradier import tradierFunctions logger = logging.getLogger(__name__) class TradierStreamConsumer(WebsocketConsumer): async def connect(self): await self.accept() logger.info("WebSocket connection established") uri = "wss://ws.tradier.com/v1/markets/events" async with websockets.connect(uri, ssl=True, compression=None) as websocket: payload = { "symbols": ["SPY", "NVDA"], "sessionid": tradierFunctions.createStreamingSession(), "filter": ["quote"], "linebreak": "true" } await websocket.send(json.dumps(payload)) logger.info(f"Sent payload: {payload}") async for message in websocket: logger.info(f"Received message: {message}") await self.send(text_data=json.dumps({"message": message})) urls.py: urlpatterns = [ ... path('api/tradier/stream', TradierStreamConsumer.as_asgi()), ] I expected continuous JSON data being streamed to the web page, but in reality I get this: Also, this is my console output when I log the info: -
"<Model: ModelInstance>" needs to have a value for field "id" before this many-to-many relationship can be used
Currently getting this error between my UserProfile model and Song model when I try to get all user songs "song = user_prof.songs.all()" and error is the title "<UserProfile: ...>. This is my first time using a through model for two models (Song and Note) and am suspicious.

WordPress blog in Subdirectory of Django site on cPanel
I've gone through several similar posts here on StackOverFlow but I can't get it to work. What I want to achieve is to load any url that contains /blog/ with WordPress.

How can one enable a mix of authenticated and unauthenticated websockets using Django Channels?
I'm running a Django application with DRF and Channels and I've configured a number of websockets, one of which I need to be open/insecure. However, all I can figure out is how to enable/disable security at the application level, not at the consumer specific level. Here is the asgi.py configuration: application = ProtocolTypeRouter( { "http": django_application, "websocket": AllowedHostsOriginValidator( AuthMiddlewareStack(URLRouter(websocket_routing.websocket_urlpatterns)) ) } ) Alternatively, to disable the authentication, I can switch the websocket entry to URLRouter(websocket_routing.websocket_urlpatterns) With the DRF views, its easy enough to disable authentication: class WebhookCallEvents(APIView): authentication_classes = [] permission_classes = [] But these properties don't seem to work in a consumer class: class MyConsumer(AsyncWebsocketConsumer): authentication_classes = [] permission_classes = [] How would one enable authentication for some websockets but have it disabled for others within the same application? Looks like this is a duplicate of this question over here: Django Channels 2 websockets multiple AuthMiddlewareStacks However, none of the answers are accepted, so perhaps restating the question will yield some results. -
Django: Views and URLs Configured, but Pages Not Found (404 Error) - only /admin shows
I'm encountering an issue with my Django project. I've set up views and URLs for several pages like 'landing', 'chat', 'impressum', 'sales', 'team', and 'user'. However, when I try to access these pages in the browser, I receive a 404 error indicating that the pages cannot be found. Here's the relevant code I've implemented: from django.contrib import admin from django.urls import path from . import views urlpatterns = [ path('admin/', admin.site.urls), path('', views.landing, name='landing'), path('chat/', views.chat, name='chat'), path('impressum/', views.impressum, name='impressum'), path('sales/', views.sales, name='sales'), path('team/', views.team, name='team'), path('user/', views.user, name='user'), ] # views.py from django.shortcuts import render def landing(request): return render(request, 'landing.html') def chat(request): return render(request, 'chat.html') def impressum(request): return render(request, 'impressum.html') def sales(request): return render(request, 'sales.html') def team(request): return render(request, 'team.html') def user(request): return render(request, 'user.html') # settings.py import os TEMPLATES = [ { 'BACKEND': 'django.template.backends.django.DjangoTemplates', 'DIRS': [os.path.join(BASE_DIR, 'teacherassistant/templates')], 'APP_DIRS': True, 'OPTIONS': { 'context_processors': [ 'django.template.context_processors.debug', 'django.template.context_processors.request', 'django.contrib.auth.context_processors.auth', 'django.contrib.messages.context_processors.messages', ], }, }, ] Despite correctly defining URLs and views, I'm unable to render the respective HTML templates for each page as intended. It seems like there's an issue with how Django is handling the routing.[enter image description here]enter image description here -

Django reverts model value saved by form in POST (Ajax) when I call query by GET (Ajax)

Django - Create a model that holds aggregated Foreign Key values
I have a Django Model defined as a ServiceEvent, and another defined as Part. class ServiceEvent(Model): date = DateTimeField(null=False, blank=False, db_column='date', default=datetime.now()) vehicle = ForeignKey(Vehicle, on_delete=models.CASCADE) description = TextField(null=True, blank=False, db_column='description') # The contents of the notifications to create for this event. notification_contents = TextField(null=True, blank=False, db_column='notification_contents') # The mileage the event should occur. target_mileage = DecimalField(max_digits=10, decimal_places=2, null=True, blank=False, db_column='target_mileage') # The mileage at the time of the event. event_mileage = DecimalField(max_digits=10, decimal_places=2, null=True, blank=False, db_column='event_mileage') class Part(Model): part_number = CharField(max_length=100, null=False, blank=False, db_column='part_number') description = CharField(max_length=100, null=False, blank=False, db_column='description') price = DecimalField(max_digits=10, decimal_places=2, null=False, db_column='price') service_event = ForeignKey(ServiceEvent, on_delete=models.CASCADE) Since there can be multiple Parts per ServiceEvent, is there a way to store a column in the ServiceEvent table that contains the price of all of the parts added up that belong to a given event? I would like to do this for efficiency however I'm not sure if there is a better approach (like using a mapping table, which may still lead to the same question about the column). FYI: I'm using SQLite currently. Thanks! -
Heroku - Django - How to reduce cool down of keep alive
I have an API that creates a model object whenever an action is true. Slight problem, everytime the API sends some data it creates a connection and these connections dont seem to cool down very quickly. Connections seem to stay on for more than 60 minutes. This results in getting the following error: too many connections for role xxx As a result, I implemented the following code in my prod.py: from .base import * from decouple import config import django_on_heroku # Heroku Settings django_on_heroku.settings(locals(), staticfiles=False) # Adjust database settings import dj_database_url DATABASES['default'] = dj_database_url.config(conn_max_age=450, ssl_require=True) This was implemnted following Heroku's guidlines : https://devcenter.heroku.com/articles/python-concurrency-and-database-connections What I was hoping to achieve here was to have connections lasting a maximum of 45 seconds. (users dont need to spend more than 20 seconds on the site to get what they need). I seem to be missing something. Would you be able to shed some lights? Is there a better practice to ensure connections do not reach their limit? Edit: worth mentioning, I am on the Basic plan. Planning to move to Standard0 when ready for production. I am assuming the plan shouldnt affect the ability to define keep alives. -
Django How to Have an Internal Link on Custom Button Component
I am on DjangoCMS 3.11.3. I am not a Django developer, I primarily do .Net but was asked to help out with CSS and HTML. That went well, so now we are here... We currently have an imported Bootsrap4 Link/Button component that has far more options than the PM wants and than what the end users need. This imported plugin has 2 levels to the Internal Link and the 2nd level is hierarchical (indented) as show below: I seem to be able to have an internal link created in my custom Button component, but it only has a single dropdown of pages (each has a duplicate for some reason, the values of th duplicates are different if that means anything) and they are not indented (hierarchical) at all. I have been googling and such with no real success. I was able to dig into the repos and such to get some of the source code but it was getting insanely deep how far the spaghetti code was going. This is where you come in. I just want a simple component that lets the user pick a page within the CMS. I understand why all of the inheritence and such is … -
Django ORM: Case When not working when output is a Subquery producing a list of Ids?
I've been spending an incredible amount of time today on something I don't understand at all. Let me explain: I have a code similar to this one: puzzle_sequence__puzzles = <a subquery> puzzle_sequence__puzzles_3d = <another subquery> MyModel.objects.add_only_3d_puzzle_sequence().exclude(puzzle__in=Case( When(Q(only_3d_puzzle_sequence=True), then=Subquery(puzzle_sequence__puzzles_3d)), default=Subquery(puzzle_sequence__puzzles) )) which throws an error sqlite3.OperationalError: near "CASE": syntax error django.db.utils.OperationalError: near "CASE": syntax error or django.db.utils.ProgrammingError: (1064, "You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'CASE WHEN CASE WHEN (`games_play`.`puzzle_sequence_id` IS NOT NULL AND CASE W...' at line 1") depending if I'm on sqlite3 or MariaDB server I've been toying with it for some while now, and it seems that's it's really the Case When statement which raised the issue as both the following statements work well: MyModel.objects.add_only_3d_puzzle_sequence().exclude(puzzle__in=Subquery(puzzle_sequence__puzzles_3d)) MyModel.objects.add_only_3d_puzzle_sequence().exclude(puzzle__in=Subquery(puzzle_sequence__puzzles)) I however don't understand at all why my Case When statement would fail Is there a specific issue if the output_field of a Case When statement should be a list of objects or list of object ids ? PS: as you can see, I'm not using Postgres, so I guess I cannot force output_field=ArrayAgg Thanks in advance -
QUALIFY on a non-window field
As stated here, from 4.2 Django supports fIltering against a window function. I've tried it and Django successfully creates a QUALIFY clause when using a window field in the filter clause. However, if using, let's say, a model field, the predicate is assigned to the WHERE clause. That arises the next problem: qs.annotate( position=Window( expression=RowNumber(), order_by=order_by ) ) obj = qs.get(id=obj.id) # obj.position will always be 1, as WHERE is run before QUALIFY -

Here are the models I've set up (relevant fields only) #models.py class Game(models.Model): gamecode = ShortUUIDField(length=4, max_length=4, unique=True) phasenumber = models.IntegerField(default=1) isActive = models.BooleanField(default=True) class Player(models.Model): game = models.ForeignKey(Game, on_delete=models.CASCADE) user = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE) isPlaying = models.BooleanField(default=True) class PlayerVote(models.Model): byplayer = models.ForeignKey(Player, on_delete=models.CASCADE) forplayer = models.ForeignKey(Player, on_delete=models.CASCADE, related_name="voteforplayer") gamephasenumber = models.IntegerField() timestamp = models.DateTimeField(auto_now_add=True) When a user joins a game, they get an entry in the "Player" model. When they cast a vote for another player, an entry is added to the "PlayerVote" model showing which player voted (byplayer), who they voted for (forplayer), and the phase that the game is in (gamephasenumber) (this is just an integer that increases each phase of the game) What I'd like to do is create a QuerySet which contains each player and how many votes they got in this phase of the game. I can do the below to get the votes they've received for all phases playerswithvotes = Player.objects.select_related('game').filter(game = activegame.game, game__phasenumber = activegame.game.phasenumber, isPlaying = True).annotate(votesreceived=Count('voteforplayer')).order_by('-votesreceived') But how … -

Trial 1: class UserAdmin(ImportExportModelAdmin): list_display = ('username', 'email'....) admin.site.unregister(User) admin.site.register(User, ImportExportModelAdmin) Trial 2: class UserAdmin(ExportMixin, admin.ModelAdmin): list_display = ('username', 'email'.....) admin.site.unregister(User) admin.site.register(User, UserAdmin) Restarted the development server. the django-import-export is in INSTALLED_APPS in settings.py Expected behavior: The "Export selected" button should appear in the Django admin user list view. Actual behavior: The button is not displayed. My Question: Why the button is not showing and how can I fix it. Any suggestions or insights into why the button might not be showing would be greatly appreciated. -
Django, Settings module not found on YouStable hostings
I have been deploying django websites on a shared hosting platform (YouStable). With my latest attempt I get a 500 server error page, because it can’t find the settings file. Background I did previously manage to deploy a site that worked. I deleted that when I had problems because I had chosen app names that conflict with reserved words and I also discovered I could pip install the Bootstrap web framework (although I need to sort this issue first). I have since had problems creating a new site. I reported a problem when the hosting server was trying to run code from a virtual environment connected to a previous site ( the site and venv have been deleted). The hosting support techies have fixed that. What I did. The procedure for deployment involves creating a Python ‘app’ in CPanel's ‘Setup Python app’ by; selecting a Python version (I chose 3.11), choosing a name (‘myapp’), selecting the domain name and saving the app. This creates a virtual environment (or venv) using my username (‘username’), the app name and the Python version. For me: /home/username/virtualenv/appname/3.11/ CPanel then displays the code to select and activate this venv for use in the terminal section … -
slider input ranges in html with min and max values inside a table and a for loop
I'm a newbie and battling my first issues with Django, html, js and so on.. I wonder if anyone can help me out here. I have a page where you must enter a series of ranges of attendances and prices for a movie center. If you purchase entrances to a movie if you go to the movies once you pay 8, if you plan to go from 2 to 5 times you pay 20 but if you plan to go 6 to 10 times you pay 30. what I'm getting is this The thing is that the list will grow every time you make a new range of prices. I can forsee someone adding another range from 11 to 20 times and paying 35$. ` #visit range <th scope="col">Precio</th> <th></th> </tr> </thead> <tbody> {% for cuota in cuotas %} <tr> <td><input name="range" id="range" min="0" max="100" value="0" type="range"></div> <td><a class="price">{{ cuota.price }}</a></td> <td style="text-align: right"> <button type="button" class="btn btn-secondary btn-xs text-align-right"><i class="fas fa-edit"></i></button> <button type="button" class="btn btn-secondary btn-xs"><i class="fas fa-trash-alt"></i></button> </td> </tr> {% endfor %} </tbody> </table> </div> </div>` The thing here is that the list will grow and I should have an unique ID for each slider and so on. … -
