Elastic BeanStalk Django Error in Pipfile
This is my first time deploying on AWS Elastic BeanStalk. I have built an application https://github.com/ChristopherPHolder/dribblz and decided I should deploy it on Elastic BeanStalk so I tried to follow their tutorial on https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/create-deploy-python-django.html I have been trying to deploy it for 2 days now but don't know what else to try. It seems like there are many questions here related to Elastic BeanStalk but not all of them have answers and non of them seem to have the same issue as me. I get this error: ERROR: ServiceError - Create environment operation is complete, but with errors. For more information, see troubleshooting documentation. And if I inspect the logs I can narrow down the error to a problem with pipenv in the pipfile. [ERROR] An error occurred during execution of command [app-deploy] - [InstallDependency]. Stop running the command. Error: fail to install dependencies with Pipfile file with error Command /bin/sh -c /usr/bin/python3.8 -m pipenv install --skip-lock failed with error exit status 1.

How to implement django-gssapi 0.9b3
I recently asked if anyone knew how to fix an issue I have with an Python/Django application that I integrated with IIS. The problem is that IIS buffering is overriding my use of the Django yield function to return output to the browser in real-time - my question was never answered and has been deleted. I only used IIS to front the application so that users would be made to sign-in using their windows credentials. Now I've decided to remove IIS altogether as I want my Django yield functionality back plus, I only have five users of the application - so I'm going to use the Django provided web server. To substitute the requirement for my users to logon using their windows credentials I would like to implement the python library 'django-gssapi 0.9b3' which would provides GSSAPI authentication for Django and in-turn, a transparent logon experience for my users. I would like to ask if anyone anyone has experience implementing this library to allow SSO for windows clients using Kerberos and if so, could you please share links for examples / instructions on how to get this library working with Django? I'm using Django 3.2.3 and Python 3.6.8 running on … -

Python/Django ModelViewSet API with routers Page not found (404)
I'm trying to build a geolocation API with Python and Django. I already have a ModelViewSet API endpoint to display Providers at the URL http://localhost:8000/Providers and the Provider's details at http://localhost:8000/Providers/{id}. I need to add another ModeViewSet to the endpoint /Providers/{id} so that I have an API endpoint /Providers/{id}/Polygons to display all polygons created by the provider with that id. Therefore visiting the URL http://localhost:8000/Providers/{id}/Polygons should display all polygons created by Provider with that id and subsequently the details of that polygon. How can I better create the url routers or the API ModelViewSet. Thanks in advance. The code I have keeps telling me this. Page not found (404) Request Method: GET Request URL: http://127.0.0.1:8000/providers/1/polygons .... ^ ^providers/<int:pk>/polygons/$ [name='polygons-list'] ^ ^providers/<int:pk>/polygons\.(?P<format>[a-z0-9]+)/?$ [name='polygons-list'] ^ ^providers/<int:pk>/polygons/(?P<pk>[^/.]+)/$ [name='polygons-detail'] ^ ^providers/<int:pk>/polygons/(?P<pk>[^/.]+)\.(?P<format>[a-z0-9]+)/?$ [name='polygons-detail'] ^ ^$ [name='api-root'] ^ ^\.(?P<format>[a-z0-9]+)/?$ [name='api-root'] The current path, providers/1/polygons, didn't match any of these.

How can objects be reordered using django-sortedm2m?
A Collection object can contain several Item objects, and an Item object can be contained by several Collection objects. The items should be ordered in each collection. I am using django-sortedm2m: from sortedm2m.fields import SortedManyToManyField class Item(models.Model): pass class Collection(models.Model): items = SortedManyToManyField(to=Item) >>> item_1 = Item.objects.create() >>> item_2 = Item.objects.create() >>> collection = Collection.objects.create() >>> collection.items.set([item_2, item_1]) >>> collection.items.all() <QuerySet [<Item 2>, <Item 1>]> As expected, the order of items as they have been added is preserved. However, I want to reorder these elements, in the spirit of a "classic" model with ForeignKeyField and order_with_respect_to: collection.set_item_order([1, 2]). What is the best or simplest way to do that? -
Django : generate a file then save it in a FileField
I have a model Contract. When users create a new Contract, they only have to provide the name. Then, my code will generate a file, and save it in contract_file which is a FileField. For this, I have a static method for generating the file, then I overwrite the save method of django's Model. class Contract(models.Model): name = models.CharField(max_length=150, null=True) contract = models.FileField(upload_to = 'contrats/', blank=True, null=True) def save(self, *args, **kwargs): filename = self.generate_contract() f = open(filename, "r") self.contract.save(filename, f) return super(Refund, self).save(*args, **kwargs) @staticmethod def generate_contract(): filename = settings.MEDIA_ROOT + 'test.txt' f = open(filename, "w") f.write("content") f.close() return filename Unfortunately, this results in an Exception Value: maximum recursion depth exceeded while calling a Python object I suppose that when I call the FileField save method, it might somehow also call the Contract' save method. But I could not solve this problem. Does anyone have a method for performing this file generation then saving it ? -
Django values method - related objects in list [closed]

Docker auto reload not working on remote server
I've setup a Django project that runs in Docker. I want to have my dev environment on a remote server and have it auto reload as I change my files locally. I've set up remote deployment in Pycharm and it works fine. All local changes are reflected on my remote server, I can also see that files get changed inside the Docker container as I've setup a volume in my docker-compose file. However auto reloading is not working, and I cannot figure out why. -

Why do I keep getting 403 Error using Nginx?
I am new to nginx so I am not sure I am understanding it right. What I am trying to is the following redirect: subdomain.domain.com -> subdomain.domain.com/something My config looks like this: server { listen 80; root /MyUser/django-app/example; server_name ~^(?<subdomain>.+).domain.com$; location ~ ^/$ { return 301 http://subdomain.domain.com/something$request_uri; } } Now when I go to subdomain.domain.com I am correctly redirected to subdomain.domain.com/something but I keep getting the 403 Error. When the redirection happens Gunicorn should check the urls.py from my django project and provide the correct view. I think I am missing something but I cannot figure out how to solve this. I can provide additional information if needed. -

Cross queries in django
