Django chunked upload on apache
I am running a Django application on an Apache2 server, but each time I try to upload a file, I get a PermissionError: [Errno 13] Permission denied: '/chunked_uploads' error. I already gave permission to write into the chunk_uploads directory, but it did not work out either. Does some have an idea how to fix it? My config file: <VirtualHost *:80> Alias /static /home/usr/app/static <Directory /home/usr/app/static> Require all granted </Directory> <Directory /home/usr/app/backend> <Files wsgi.py> Require all granted </Files> </Directory> WSGIApplicationGroup %{GLOBAL} WSGIDaemonProcess app python-path=/home/usr/app python-home=/home/usr/app/appEnv WSGIProcessGroup app WSGIScriptAlias / /home/usr/app/backend/wsgi.py WSGIChunkedRequest On # The ServerName directive sets the request scheme, hostname and port that # the server uses to identify itself.

Django use urls with same ending
I ahve a django project with the application web-api and the following url configuration: main project urls.py urlpatterns = [ path('admin/', admin.site.urls), path('web-api/', include('webapi.urls')), ] application web-api/urls.py urlpatterns = [ path('<param1:param1>/summary', Param1Summary.as_view()), path('<param1:param1>/item/<int:id>/summary', ItemView.as_view()), ] The /web-api/param1/summary endpoint works but /web-api/param1/item/12121/summary does not work and returns a 404 status code. If I change the <param1:param1>/item/<int:id>/summary' to <param1:param1>/item/<int:id>/whatever, in the web-api/url.py I get the desired results. I have tried using url regex without succees. Any ideas on how to solve the problem? Thanks in advance! -

How to change seed packages versions when creating virtualenv?
I am running into an issue when deploying a django-rest-framework API to production. The addition of seed packages pip, setuptools and wheel upon virtualenv's creation causes my deployment to fail. It appears that the specific version of setuptools (59.1.1) used here prevents usage from Newlines (related to this issue) which are used in the description of django-hijack==2.10.1 and causes the following error. This behaviour has been reverted in the newer versions of setuptools (from 59.4.0). Thus I would like to pin the version of setuptools added in seed packages upon virtualenv creation to make sure my deployment succeeds but I have no idea if/where I can set added packages versions.

How to change dates when filtering a queryset in Django?
I want to display a list of all payments done by the company. But I want to be able to filter the dates, only showing payments for example: In the last 30 days In the last 90 days Between two specific dates Now, I know I can filter in my views between two dates, or before today for example. But how I can I do this using something like a dropdown or a Data chooser on the template? Something like this for reference. For reference, the payments model would be this: class Payment(models.Model): name = models.CharField(max_length=250) date = models.DateField(default=datetime.now) value = models.DecimalField(max_digits=10, decimal_places=2, validators=[MinValueValidator(0.00)]) -

Google Cloud App Engine (Django) and Google Cloud Storage working on a Single Domain with Custom URLs
I have a Django application working on supereye.co.uk. Django handles all URL routing such as supereye.co.uk/signin supereye.co.uk/watch etc. I am also using Google Cloud Storage that is working with Google Cloud App Engine on gs://production2.supereye.co.uk How shall I handle the routing so both App Engine and Storage can be accessible through the supereye.co.uk domain. For instance : supereye.co.uk -> Django App, Google Cloud App Engine data.supereye.co.uk -> Google Cloud Storage bucket, gs://production2.supereye.co.uk Is there any way to achieve this without relating Django App to bucket at all ? Can the bucket be accessible by its own resources? Is there any internal Google Cloud tool that will let me achieve this ? -
Best way to handle articles with Django
I'm looking for the best possible way to manage articles in Django. My idea was to load the articles as static files (there's no upload from users, so no form necessary, I guess), then create the model, but which field type to use here ? Textfield or FilePathField (in the static ?) or something else ? Then create the view and render it. The articles will be showned as cards with a summary on the index page, and each card will point to the full article page. If someone would point me in the right direction, I would appreciate. I'm checking the docs since yesterday, I might have missed the relevant part. -
Add custom admin actions to django irrelevant to objects
I want to add admin actions (for example with buttons) to django admin site that are irrelevant to particular model, for example doing administrative tasks such as optimizing database or clearing cache or log files or deleting records from multiple tables... I have seen django admin action without selecting objects, but the answers seems tricky and the solutions was selecting objects of particular model, in other ways. Is there a better to add this functionality to admin site anyway? -
How Django works with Mongodb
I need to make a Django restful api. I have a volume of data that is distributed in a tree structure with 3 attachments. I want to implement this nesting in Mongo: base->collection->object. The objects are generally the same so I don't really want to prescribe millions of models. I can draw an analogy with library: hall->stack->book. Each shelf has different books on it, but all of them are made of paper and covers. I found how to work with different databases and how to send the model to a certain database: 'default': { 'ENGINE': 'djongo', 'NAME': 'some_name', 'CLIENT': { { "host": "mongodb://.........../", } }, { "user": { 'ENGINE': 'djongo', 'NAME': 'some_name2', 'CLIENT': { { "host": "mongodb://......../", } } And accessing different databases Author.objects.using('other').all(). How to relate one model to one collection I found too: class MongoMeta: db_table = "some_collection_name" But how to combine all this I can't find. That one model can belong to different databases to different collections while being one single. -

How to post foreign key id only once in Django
class Department(models.Model): name = models.CharField(max_length=50) class Employee(models.Model): name = models.CharField(max_length=100) age = models.IntegerField() department = models.ForeignKey(Department, on_delete=models.CASCADE) I'm really wondering how to do this. Suppose there are three departments with id 1, 2, 3. So in employee model if i posted some employee with name abc and department 1. So next time if i will try to post the same department id that is 1 for another employee. I should not be able to do that. Validating this field does not work i believe because of foreign key.So how to achieve this. Any help would be really appreciated. Thank you !! -
I/O time differing on docker containers

Convert a timestamp to a DateTime field?
