I'm developing a project in Django in which I'm using a view(verify) to verify the student's login details. If the student is valid user then it'll redirect to a page(display.html) where all the details of that particular student is displayed. How can i pass the object containing the student details from verify view to the display.html?? -
Is there a penalty for including extra template_tags in Django templates
I am reviewing a big Django project where extra template_tags are loaded on top of the template files. Are the template tags file loaded even if they are not used within the template file? Any other best practices around this? -

Daphne on Google App Engine Flexible for Django Channels app: 502 Bad Gateway Error nginx
I'm new to web development so I appreciate some hand-holding by the smart folks here. I'm trying to switch from gunicorn to Daphne for my Django app on GAE Flex, since I need to use Django Channels. I see many questions on SO (and other tutorials online) on how to use daphne on standalone linux machines but not on app engines like GAE Flex. Previously the site worked fine with gunicorn as entrypoint (in the app.yaml file). I just replaced it with daphne (I'd like to avoid changing nginx configurations, Unix sockets etc so I guess I'm ok with Daphne serving both HTTP and ws requests). So now my app.yaml looks like: runtime: python env: flex runtime_config: python_version: 3 entrypoint: daphne -b 0.0.0.0 -p 8001 my_project_name.asgi:application I've already made a .asgi file next to my .wsgi file and declared an application there. In requirements.txt I've ensured the daphne(2.4.1) and asgiref(3.2.3) packages are the latest versions. Finally when I do 'gcloud app deploy', deployment appears to happen smoothly and in the build logs I can see: Step #1: Step 9/9 : CMD exec daphne -b 0.0.0.0 -p 8001 my_project_name.asgi:application Step #1: ---> Running in c6f3762a5ce2 But I'm getting a 502 Bad … -

How do I use Node.js to read server file within a Django application?
I have a django application that I use to visualize data. The data itself is in an Amazon S3 bucket, and the plotting of the data is done using bokeh. One of the applications however, uses d3 instead. And while I managed to configure the bokeh apps to work properly, I don't know how to do that with the d3 app. It has to read data either directly from S3 or locally (If I download it within django views before rendering the web page) and plot it. But whatever I try I get a 404 Not Found error. I'm learning as I go, so I don't know what I'm doing wrong. Going through SO, I found this question which gives an example of downloading a file from S3 using Node.js, but I am already running a django server so I don't know if that works. I should also mention that the files to be read are quite large (several megabytes). So, to summarize, my question is: Is using Node.js my only solution here and can it be done without having both Nodejs and django running at the same time? I'm worried that this might be too complex for me to … -
Trying to convert a string in urls.py in django to all lowercase?
Essentially, I am trying to convert a dynamic url in the form of example.com/products/productName/ into a url where the productName is all lowercase. In urls.py, I have path('products//', product_detail_view)...this should redirect to a product detail page with the productName (whatever that might be) in all lowercase. I tried appending .lower() to the 'products//' and that turned the field productName into productname which is not a recognized field in models.py. I then tried 'products//' which also didn't work at all? Anyone have any suggestions? -
Redirect to user change form in Django Admin
I have almost completed adding a PIN number field for users in the Django admin. previous question I have a separate form to change the PIN number, very similar to that seen when changing a password. I have an issue with the successful redirect after a form submit. I would like to redirect back to the user change form, but have been able to do so. What is the url pattern required to redirect to that page on a successful redirect? When submitting a new password successfully you can redirect back to the user change page therefore it is possible. -
Perfect way of using Django services in one container?
I have a Django project with a few microservices which heavily rely on django infruscucture itself. It is not possible to cut them out in sepate comtainers, unless I agree to bascially multiple the same project in different containers and use separate CMD or ENTRYPOINT at the end of each DOCKERFILE. I fount no better solution and did it that way. So now my docker-compose.yml consists out of this: dg: &dg image: python:3.7.6-alpine command: .... --> ( gunicorn --config ./gunicorn.conf.py core.wsgi:application) dg_socketshark: <<: *dg restart: on-failure ports: - 9011:9011 command: /start-dg_socketshark.sh --> (python -u manage.py run_binance) dg_run_telegram: <<: *dg restart: on-failure command: /start-dg_run_telegram.sh --> (python -u manage.py run_binance) .... other services ..... Now I got the same source folders copied in different images. It works. But the total images size is 3 times bigger than th origin folder itself. ❯ docker images REPOSITORY TAG IMAGE ID CREATED SIZE python 3.7.6-alpine a139f223ffae 9 hours ago 696MB ..... But is there a better way to use one image with microservices in it, rather than copying the same source over and over? -
Django - django-privacy-mgmt package not displaying html
I need help implementing this package this package into this django project: When viewing the page source, I see the app's HTML loaded from the render tags. But on the actual page, I am not seeing any of the outputted HTML from those render tags. Can someone please summarize a step by step set of instructions to get this package to work? The instructions provided can be confusing sometimes. I did not do the following and am not sure how to do these parts: 1) install the add-on on divio.com or via pypi (would rather not install this since it seems to costs money - unless there is a way to use it for free) 2) update your templates/django_privacy_mgmt to reflect your frontend toolchain situation (not sure where in my project to put these files. 3) Then check what kind of tracking items your website is using (either in the templates or via Google Tag Manager or in any imaginable other way) and add them in the "Django Privacy Mgmt" section of the Django Admin interface to the list of 'Tracking Items'. This is necessary so that we can show a list of tracking items to the user in the … -
Default image for imagefield doesn't store the default image

Copying the django database - PostgreSQL
I use this library to copy a database. In my view I added the following code: def MyCommand(BaseCommand): def handle(self, *args, **kwargs): # All this method needs is the path to your CSV. # (If you don't provide one, the method will return the CSV as a string.) NewCar.objects.to_csv('/home/app/app/cars.csv') CarBrand.objects.to_csv('/home/app/app/brands.csv') CarModel.objects.to_csv('/home/app/app/models.csv') Province.objects.to_csv('/home/app/app/provinces.csv') Img.objects.to_csv('/home/app/app/image.csv') ImgFile.objects.to_csv('/home/app/app/image_file.csv') and tries to copy via command python manage.py mycommand but it's return Unknown command: 'mycommand'. How can I fix it? I tried to create a file called "mycommand.py" in the folder next to manage.py and in the folder next to settings.py. But I still can't copy my database correctly. I will be grateful for any help (for each how to fix a mistake or copy using a different library). -
Format numbers in Django with Intcomma
I am having issues trying to use |intcomma to format a number. Let's say I multiply the values a and b which adds up to 1000000 by using: <h2>{% widthratio item.a 1 item.b %}</h2> All examples out there use intcomma with only one value: <h2>{{ item.a|intcomma }}</h2> So my question is, how do you combine widthratio with intcomma in order to get the multiplied number formatted as 1,000,000. Example below which do not work: <h2>{% widthratio value|intcomma 1 value|intcomma %} -
Django create a model by sending an email
I have a simple CRUD app written in Django. Is there the possibility to create a model instance, passing its attributes by sending an email to the web server that host my applucation?

Is there any reference about this? Thanks -
How to setup a User model in a Postgresql db with Django?

Does Django automatically URL decode values
If I have a django app that accepts data at /XXXX/, will Django pass me (in the view) the url-decoded or url-encoded data? Mock-up Example: def view(req, s): return HttpResponse("Is this URL-decoded? : " + s) urlpatterns = [ ..., path('<str:s>/', view), ..., ] -
zipfile write dont find files in gcloud
Im trying zip a few files from Google Storage. The zipfile of Python doesnt find the files in gcloud, just in the project. How can I do for my code find the files in gcloud? zip_buffer = io.BytesIO() with zipfile.ZipFile(zip_buffer, 'w') as zip_file: for revenue in revenues: # queryset with files a lot, so, for a each file, add in zip t = tempfile.NamedTemporaryFile() t.write(revenue.revenue.name) if revenue.revenue.name: t.seek(0) with default_storage.open(revenue.revenue.name, "r") as file_data: zip_file.write(file_data.name, compress_type=zipfile.ZIP_DEFLATED) # the code dont pass from this part t.close() response = HttpResponse(content_type='application/x-zip-compressed') response['Content-Disposition'] = 'attachment; filename=my_zip.zip' response.write(zip_buffer.getvalue()) return response In this part, I write the file that I opened from gcloud, but stop inside the function: def write(self, filename, arcname=None, compress_type=None): """Put the bytes from filename into the archive under the name arcname.""" if not self.fp: raise RuntimeError( "Attempt to write to ZIP archive that was already closed") st = os.stat(filename) # when I try find the file, the command os.stat search in project, not in gcloud the "os.stat(filename)" search for a file in project, how can I do for find in the gcloud? -
Django - Postgress - atomicly create instance only if doesn't exist
I want to create an element, but only if a 'similar' object doesn't exist. For example: name_to_be_created = "John" age_to_be_created = 15 if not Person.objects.filter(name=name_to_be_created, age__gte=age_to_be_created).exists(): Person.objects.create(name=name_to_be_created, age=age_to_be_created) Note that intentionally the condition is not simple enough to allow using get_or_create As I understand it using a transaction when using select and then insert doesn't guarantee this kind of consistency I'm using Postgres
