Internal server error running Django on Heroku accessing from browser
I think this is a simple fix, but I've deployed quite a few Django apps to Heroku and I still can't figure out what's going on. Accessing https://dundjeon-finder.herokuapp.com/ gives me a 500 error when using the browser/curl, but if I shell into the app using heroku run ./manage.py shell I can render the views no problem. My logs aren't telling me anything (just that the response is 500), and Sentry isn't receiving an error (it has previously when the database env variable was set badly), so I'm assuming it's something to do with the way the request works. The repo is public, any help would be much appreciated! The settings file is here. -
Virtual environment for Django in ubuntu 20.04
After installing Django, I install virtual environment by using the command - pip3 install virtualenvwrapper-win.Also run sudo pip3 install virtualenv Added the following to the end of the .bashrc file export WORKON_HOME=~/virtualenvs export VIRTUALENVWRAPPER_PYTHON=/usr/bin/python source ~/.local/bin/virtualenvwrapper.sh then source ~/.bashrc gets successfully executed. But when I run this command - mkvirtualenv test to create virtual environment, I am getting this- created virtual environment CPython3.8.5.final.0-64 in 94ms creator CPython3Posix(dest=/home/rudrakshi/.virtualenvs/test, clear=False, no_vcs_ignore=False, global=False) seeder FromAppData(download=False, pip=bundle, setuptools=bundle, wheel=bundle, via=copy, app_data_dir=/home/rudrakshi/.local/share/virtualenv) added seed packages: pip==20.3.1, setuptools==51.0.0, wheel==0.36.1 activators BashActivator,CShellActivator,FishActivator,PowerShellActivator,PythonActivator,XonshActivator Command '' not found, but can be installed with: sudo apt install mailutils-mh # version 1:3.7-2.1, or sudo apt install meshio-tools # version 4.0.4-1 sudo apt install mmh # version 0.4-2 sudo apt install nmh # version 1.7.1-6 sudo apt install termtris # version 1.3-1 I also installed the mailutils-mh but still getting this. -
Is it possible to use Azure Shared Access Signature outside of Azure?
Since Azures Shared Access Signatures (SAS) is an open standard I want to use it in my Django application which has no links to Azure whatsoever. I basically want to create a piece of code that creates read permission for the next 24 hours on a specific url I'm serving. So I've watched some video's on SAS and I installed the python library for it (pip install azure-storage-blob). I read over the README here on github but as far as I can see it always requires an Azure account. Is it also possible to use SAS in my own (Python) application? I imagine it to create the hashes based on a pre-defined secret key for. If this is possible, does anybody have any example code on how to create the url and how to validate it? Preferably in Python, but example code in other languages would be welcome as well. -
Python-Django-Heroku not able to locate images in heroku, images not visible
so I recently deployed my django/python website (that used sqllite as a database) to heroku which hosts websites for free, everything is functioning normally like when I used to run localhost in my browser, except that this project is using postgressql database with heroku and images aren't appearing on my website, I looked everywhere and I think it has to do with the uploads file in the database(the path of the image is still the same but the location of the image changed). local host image link: "http://localhost:8000/image/download/uploads/products/white_shirt_MERETfT.jpg" heroku image link: "https://supremelebanon.herokuapp.com/image/download/uploads/products/offwhite_shirt_tQWa19c.jpg" it says image not found for when I load the website on heroku hosting.

How to pass object by id after saving from form using redirect?
I am sorry for asking this. I described a service that uploads an image through a form. The bottom line is that after a successful download (add_picture), I have to get to the image page (picture_detail). I don’t understand why I can’t transfer ID. I did the following: models.py: class Picture(models.Model): url = models.URLField(blank=True, verbose_name='Ссылка на изображение') image = models.ImageField(upload_to='pictures/%Y/%m/%d', width_field='image_width', height_field='image_height', blank=True, verbose_name='Изображение') def get_absolute_url(self): return reverse('home:picture_detail', args=[self.id]) views.py: def add_picture(request, id=None): picture = Picture.objects.filter(is_active=True) # picture_form = None # picture = get_object_or_404(Picture, id=id) if request.method == 'POST': form = PictureCreateForm(data=request.POST, files=request.FILES) if form.is_valid(): form.save() # picture = get_object_or_404(Picture, id=id) bb = Picture.objects.get(id=id) return HttpResponseRedirect(reverse('home:picture_detail', kwargs={'id': id})) else: return render(request, 'add_picture.html', locals()) else: form = PictureCreateForm() return render(request, 'add_picture.html', locals()) urls.py: urlpatterns = [ path('', views.home, name='home'), path('add_picture/', views.add_picture, name='add_picture'), path('picture_detail/<int:id>/', views.picture_detail, name='picture_detail'), ] As a result, I should get to a page of this kind: -

Database-Query in DjangoChannels Consumer returns coroutine object instead of query-set
I am using an AsyncConsumer from wich an async task calls a syncronous function via the asgiref sync_to_async function. In this function the result of a database query is supposed to be saved to a variable and later iterated over, but instead of the resulting queryset, the variable just saves the coroutine object. a simplified version of the code: class ChatConsumer(AsyncConsumer): ... async def collect_votes_task(self): await sync_to_async(self.process_sessions()) def process_sessions(self): current_session = self.get_current_session(self.room_name) print(current_session) # do other stuff with the query-set @database_sync_to_async def get_current_session(self, current_session_code): current_session = Session.objects.filter( session_code=current_session_code) return current_session prints: <coroutine object SyncToAsync.__call__ at 0x000001B1CBBF03C0> I am fairly new to DjangoChannels, so excuse me if the reason this happens is obvious. -

Django Date and time issue. Server ahead of timezone
I was working on an app and I can't solve the issue of date and time. In setting.py file I have set the timezone to UTC. TIME_ZONE = "UTC" USE_I18N = True USE_L10N = True USE_TZ = True I live in UTC+05 so when I publish a blog the date and time is 5 hours into the future so the blog can only publish after 5 hours.

I want to create a set of buttons (answers to the questions) in Django, how should I do this?
I want to create a quiz site with a selection buttons, it should contain answer and two buttons with answers on em. When new user would open this quiz every button should be inactive, and once he would select one of answers then it should be active (and sent to the database), he could then return to this page and see his answers and change the answers whenever he wants. I want to do this without submit button (every answer should save after clicking).

is it possible to build an app with scrapy without using command line interface?
I am building an app for scraping data from other sources, however, the URL would be entered by the user on a web page, and currently, I am using BeautifulSoup and Selenium to achieve the data and it is extremely slow.

How to prevent Django to initialize "prod" DB before test DB
I'm using Django for the backend of my project and I'm currently writing tests. The thing is when I use the command python manage.py test, it first loads my actual DB before creating the test DB. The problem is that on DB initialization, I have some processes that do stuff with the App Registry (in my software you can install/uninstall apps while Django is running). So when I use the test command, it loads my App Registry from my local DB, then it creates the test DB but it seems to be using the same App Registry (since it uses the same settings when it starts). So I have tests that fail because things are already done in the App Registry (because of my local DB), that shouldn't be. So when I do python manage.py test, the output is : I do this : print("DB : ", connection.settings_dict['NAME']) somewhere to show you DB : my-db Creating test database for alias 'default'... System check identified no issues (0 silenced). .DB : test_my-db ..... ...tests are executed... .... Is there any setting that I could use to tell Django : "Hey, I'm using the test command, do not load my local DB … -

Django don't run the collectstatic command anymore when I upload an image from admin
