No Dynos is running for Django web app on Heroku
I am working on a web app that i have made using Python, Django. After completed this app in development I have decided to host the app on Heroku so that other peoples will also visit my website to do so I signed up on Heroku and create a new app. I then pushed my app to heroku using git but whenever I visit url I get: Application error An error occurred in the application and your page could not be served. If you are the application owner, check your logs for details. You can do this from the Heroku CLI with the command heroku logs --tail When I go to resource page of my app I realize that there is no dyno instance running. I check the logs and I'm getting a H14 - No web processes running.Which suggest that my app has no dyno's indeed. I tried a lot of solution from internet and have searched all stack overflow questions related to this problem but my problem still not solved: Here is the command in my Procfile: web: gunicorn MyFirstWebsite.wsgi --log-file - Any help would be really appreciated. -
Line ChartJs does not render - Date format issue
I am trying to plot a line chart using Django and ChartJs. I created a list of dates in my view file that I would like to use as x-axis data in my chart. I rendered my list of dates in my template through built-in template tags {{ date }}. When I run the server and open my template, no issue appears, even the chart. When I inspect my html file, the list has “'” prior each date element in my list (I attached a capture). enter image description here I think this is why it does not work but I can’t figure out why I have this text in my list. I'm assuming that this is the index. I tried to convert my dates list into string but it is still the same. Do you guys have any idea ? Thank you for your help. [from django.shortcuts import render import yfinance as yf import pandas as pd from datetime import datetime as dt def HomeView(request, *args, **kwargs): data = yf.download(tickers='SAF.PA') data\['Date'\] = data.index data\['Date'\] = data\['Date'\].dt.strftime("%Y-%m-%d") context = { "Date" : data.Date\[0:5\].tolist(), "Close" : data.Close\[0:5\].tolist() } return render(request, "home.html", context)][1] -

Filtering searches with Django
I'm trying to add filters to my search with Django_Filters. But when I try to filter an already existing search, the ?q=mysearch is eliminated and after that the filters are applied. This is the code: def get_queryset(self): #this is the search part qs = self.model.objects.all().order_by('id') search = self.request.GET.get('q') if search: qs = qs.filter(Título__icontains=search) return qs def get_context_data(self, **kwargs): #here's when I try to filter context = super().get_context_data(**kwargs) MyFilter = PubFilters(self.request.GET, queryset=self.get_queryset()) queryset = MyFilter.qs search = self.request.GET.get('q') paginator, page, object_list, is_paginated = self.paginate_queryset( queryset, self.get_paginate_by(queryset) ) queries = self.request.GET.copy() queries.pop('page', None) context.update( filter=MyFilter, filtered_items=object_list, page=page, is_paginated=is_paginated, count=paginator.count, queries=queries, búsqueda=self.request.GET.get('q') ) return context Any idea on how to solve this? If you need any other piece of code, please ask. Thanks in advance! -
Deploying dockerized Django with channels + Nginx + Daphne
i have a django application, running in Docker, which is using channels 2 (for a chat app). When running docker-compose up on local, the site and websocket chat works like a charm. Now i tried to deploy the project: I want to run the whole project only on ASGI with daphne (instead of Daphne for Websocket and gunicorn for standard requests). Well, i tried it for three days now, i dont get it working. I am completey lost. The website with "standard" http requests over https is working perfect, the chat with websockets gives me a 500 error, but the error message is a miracle to me. I have really no idea, what to do next.

Python Django Best Practice for request.user in Class Based Views and Queryset
I am using class based views and have always the same problem without an elegant solution. My querysets should only show the ones that are owned of the request user. Code view: class MyListView(ListView): model = MyModel def get_queryset(self): return self.model.objects.owned_by_user(self.user) def __init__(self, **kwargs): super().__init__(**kwargs) self.user = None def dispatch(self, request, *args, **kwargs): self.user = request.user return super().dispatch(request, *args, **kwargs) model: class MyModelQuerySet(models.QuerySet): def owned_by_user(self, user): return self.filter(user_field=user) class MyModelManager(models.Manager): def get_queryset(self): return MyModelQuerySet(self.model, using=self._db) def owned_by_user(self, user): return self.get_queryset().owned_by_user(user) class MyModel(models.Model): user_field = ... objects = ProductRequestManager() Best practice 1: I think I have to overwrite dispatch to add the request.user. My IDE notes "Instance attribute user defined outside of init. In order to prevent this I also need to overwrite init(). How can I achieve this with less code? Best practice 2: Is there another way to get querysets belonging to the current user? -

Django treating DateTimeField as both UTC and America/Chicago
In my views.py I am both writing to and reading from a PostgreSQL table that has a DateTimeField. When creating a new entry, the date field is populated in UTC time. When pulling the data from the database in views.py the UTC timestamp is being treated as though it is in the timezone "America/Chicago". # settings.py TIME_ZONE = 'America/Chicago' USE_I18N = True USE_L10N = True USE_TZ = True I've tried supplying varios timezone aware dates when creating the entry in the database but it always appears as UTC when viewing the database directly. When I pull the data back django is treating the UTC datetime as if the timezone were "America/Chicago" # views.py CT = pytz.timezone("America/Chicago") UTC = pytz.timezone("UTC") # attempt_1 = datetime.datetime.utcnow().astimezone(CT) # attempt_2 = datetime.datetime.now().astimezone(CT) # attempt_3 = datetime.datetime.utcnow() attempt_4 = datetime.datetime.utcnow().astimezone(UTC) new_entry = MyModel(date=attempt_4) new_entry.save() -

Django : is there a way to create a popup window without the use of a template file?
I'm accessing instruments from a Django application (sorry if I don't use the right terms I am not a developper). One of the instrument we use must do the same measurement a few times : Once the instrument has made an acquisition, the user must do some things, inform the application, so it can starts the next acquisition. I wanted to make everything from the view to make it simpler. So basically I need to make a popup window before the acquisition, and wait for the user to close this window to start the acquisition. The messages from django need some lines in the template, but I'd like to do all this before accessing the template ? Is that possible ? Thank you for your answers ! -
Django send http response without changing page
In django, if i wanted to send back a return httpresponse but not make a new page eg: when i send a http response it becomes https://localhost:8000/appname/submit/, i want to send an http response to https://localhost:8000/appname/ and not change it? I just want a general answer nothing specialised, if any code is needed please tell me. From my research i found a question with a very similar title unfortunately it is for flask or ajax and not django focused [yes i might be able to work it out but i recently just started django so it's a bit confusing :) ] -
Header refuses to show up on mobile view
I've spent a week trying to figure this out. I'm building a django website, and I have a navigation menu that always remains hidden behind some element when I look at the website on my mobile view. On Chrome Dev Tools, it looks perfectly fine, but on my phone, it's completely gone. Example of Chrome Dev Tools vs Phone: My first step in solving this was looking at the z-index. None of the indexes I tried worked, and I made sure to search for solutions to z-indexes not working on the Internet as well, such as having necessary prerequisites. Since my navigation menu is in my base.html template file, I even moved the header down to the very bottom of the body element (it has a fixed position), so that {%block content%} was always above the header. That didn't work either. So I tried moving all elements to the left whenever the navbar was open. This is what happened. If I try inspecting this on chrome dev tools by right clicking the empty space where there should be empty space, I get the following: ...meaning the only thing that's there is the HTML file itself. I'm completely baffled. I have … -

Django FileField wont update path and url after save()
I have this model: class Galeria(models.Model): galeriaid = models.AutoField(db_column='GaleriaID', primary_key=True) nombre = models.CharField(db_column='Nombre', max_length=128, blank=True, null=True) ruta = models.FileField(db_column='Ruta', max_length=512, blank=True, null=True) And I overrided the save() to make my file look like {pk}.jpg or {pk}.mp4. The code works but it doesnt update the file.path and file.url. I get "media/{file}" instead of "media/imagenes/%Y%m/{file}".

Override django serializer or models create method
I'm trying to add data to my database.

How should I do ? When I add a Laboratoire, I have Tutelle to create ... Should I implement the create in the Models ? As I am new to django, I have hard time to understand the subtility of functions calls. -
wagtailtrans with prefix_default_language=False: root (/) not found when changing language
I am using Wagtailtrans and have set prefix_default_language=False in my urls.py. Default language is 'en'. Root page 127.0.0.1:8000/ loads as expected. When I change to another language (in my case load 127.0.0.1:8000/nl/) the translated page loads as expected. But when I then change back to root 127.0.0.1:8000/, I get Page not found. When I then load 127.0.0.1:8000/en/ I get Page not found as expected, but subsequently loading 127.0.0.1:8000/ gives me the correct English home page. So then apparently some language setting has changed. My guess is this is caused by Wagtailtrans's TranslationMiddleware, because when I use LocaleMiddleware instead, this behavior does not occur. My question: is this 'normal' or perhaps 'intended' behavior, or am I doing something wrong? It seems to me that when prefix_default_language=False, the home page should always be found. And what am I missing if I just keep using LocaleMiddleware (not recommended in docs)? settings/base.py: MIDDLEWARE = [ 'django.contrib.sessions.middleware.SessionMiddleware', 'wagtail.core.middleware.SiteMiddleware', 'wagtailtrans.middleware.TranslationMiddleware', # depends on the previous line and replaces the next line # 'django.middleware.locale.LocaleMiddleware', 'django.middleware.common.CommonMiddleware', ... project urls.py: ... urlpatterns += i18n_patterns( ... url(r"", include(wagtail_urls)), prefix_default_language=False ) Any help appreciated! -
Why background color of navigation bar in Bootstrap does not change?
