Domain-maked Django app not working as expected
I am running a Django app alongside a basic html website using Apache2, by attaching the django app through my.site/myapp When I access it like my.site/myapp/some-location it works just fine, but if I access it through my domain with masking enabled such as domain.site/some-location it returns a 404. The domain points to my.site/myapp with masking enabled as mentioned. Site configuration: <VirtualHost *:80> Alias /static /var/www/myapp/static <Directory /var/www/myapp/static> Require all granted </Directory> <Directory /var/www/myapp/myapp> <Files wsgi.py> Require all granted </Files> </Directory> WSGIDaemonProcess myapp python-path=/var/www/myapp python-home=/var/www/djangoenv WSGIProcessGroup myapp WSGIScriptAlias /myapp /var/www/myapp/myapp/wsgi.py </VirtualHost> A specific example that doesn't work: domain.site/admin, which however works well on my.site/myapp/admin. -
Way to query internal data structure for running python program [closed]
Hi I a newbie to software development, I wanted to build a python application that will open TCP connection and listen to logs and do some action based on them. I am planning to use dictionary to store my datas. Just wondering is there a way or CLI package that I can use to query the internal data structure while program is running. I googled and found flask as an option but from what I understand its mainly for web-development. Does it make sense to use Flask for these kind of my application ? Am I going in right direction or is there any other resources that will point me in right direction ? -

How to assert that a class has a class exclusive property in Django/Python?
I have two models in Django, one that is the base and the other that is inherited. The base model has a database field (which in Python is an attribute of the class) and the inherited model has a property that is exclusive to the Class (not of every instance created). Both can yield different things. from django.db import models from django.utils.decorators import classproperty class Parent(models.Model): somefield = models.TextField() class Child(Parent): @classproperty def somefield(cls): return 'something' How can I create a test to ensure that all the child models created from the parent model have that class exclusive property? Because if I use hasattr() it will consider the field and the property. Something like this assertTrue(hasattr(Child, 'somefield')) assertFalse(hasattr(Parent, 'somefield')) -

Django Can't get ListView to reorder based on date
I am attempting so change the display order of a ListView to show the most recently added item. I have tried several methods in the view but so far none has had an effect on the output. The page still displays the oldest entry first.

Passing a variable from views.py to models.py django
I am still very new to programming. My issue is this I have 2 models, one for Sale and one for Agent. now to render each Agent and the sales they made(with different attributes) uniquely I needed to write model methods under my sale model to allow to me to call them in the template. Now my issue is this, I want to be able to render that exact thing but by what dates the user chooses, I have tried manually doing this through my project files and it works, but I want to know is it possible to have those values moved from user into my method? What I mean is there is a basic form in the nav bar that allows the person to choose a from and to date, but those values I am not sure how to pass them into my models.py under the method where I need this date range applied. I will show an example. #this is my view that grabs relevant dates def asearch_stats(request): if request.method == 'POST': from_date = request.POST['from'] to_date = request.POST['to'] return render(request,"Sales/salesfilter.html",{"flookup":flookup}) # this is my model with the methods I'm referring to below: class SalesAgent(models.Model): user = models.OneToOneField(User,on_delete=models.SET_NULL,null=True,related_name="sauser") … -
Why am I not getting CSRF warning from django?
So usually when you try to make a POST request to the server in Django without CSRF token it gave you this page but for the past 3 months I've been playing with DRF and custom user model and I didn't even realized until now that I've actually not been getting that error despite not using CSRF in my postman header. There's also some more details made it more confusing to me first I made a post request to TokenObtainPairView from djangorestframework_simplejwt containing username and password (I'm using base user model) for login and it was successful Right after that I made another post request to add a title (a model that only have 1 field which is a charfield) and then it gave me CSRF warning I also have an almost identical project to this the only difference being the other projects uses custom user model and it never gave me any CSRF warning. So I suspect this has something to do with the user model somehow So to summarize my question: Why doesn't it gave me CSRF warning in the first POST request? does this have anything todo with custom user model? if so what am I missing? … -
Django DRF: Take extra input from user using serializer but not present in the model

Authenticate users in my django app using an existing ASP.Net IdentityServer login app
I'm trying to authenticate users in my django app using an existing ASP.Net IdentityServer login app. I've seen the documentation has an example for an angular or react(Javascript based app) but not django. Does anyone have some sample code or tutorial that shows how to do in django? I'm new at this. Especially when it comes to the call back. I'm not sure i need to use an open iD client package to do this. Can this work with django? I appreciate any assistance https://identityserver4.readthedocs.io/en/latest/quickstarts/4_javascript_client.html?highlight=authority#add-your-html-and-javascript-files
