Middleware presence couldn't block request from hitting the routes
I have written the middleware for Session Management, What I observe is that the Middleware is working fine up to the expectations when it comes to redirection to the desired page as per the session state. But the problem is that the routes which I have written only to be hit when the session is active, are still getting hit irrespective of session state even after the redirection. E.g: The secure home route should only be accessible when the session is set, Middleware doing their job by redirecting the page to Login, But In the server, I can see the Home route was still hit I could write again the block of code like if sessionActive: // Code Goes Here Which Should Run For Active Session State else: // Return with Forbidden Message I'm assuming Why should I write above piece of code when the middleware is in place?

Why the url works with parameter pk and not pk2?
When I try to send pk2 or any other arguement, it raises an AssertionError. What I mean is this that the url path('grade/<str:pk>/', IndividualGrade.as_view(), name="get-grade") doesnt gives me an error while the one below gives error: path('grade/<str:pk2>/', IndividualGrade.as_view(), name="get-grade"). My view is fairly simple as below: class IndividualGrade(generics.RetrieveUpdateDestroyAPIView): ''' PUT/GET/DELETE grade/{grade:pk}/ ''' queryset = Grade.objects.all() serializer_class = GradeSerializer def put(self, request, *args, **kwargs): try: g1 = Grade.objects.get(grade=kwargs["pk"]) serializer = GradeSerializer(g1, data=request.data) flag = 0 except Grade.DoesNotExist: # Create a new grade if a grade doesnt exist g1 = Grade.objects.get(grade=kwargs["pk"]) serializer = GradeSerializer(g1, data=request.data) flag = 1 if serializer.is_valid(): # call update/create here else: return Response(serializer.errors) return Response(serializer.data, status=status.HTTP_200_OK) I realized pk2 in the url works if I write my own get function (tried in another view), but I don't know how to fix this without writing my own get. While this have been discussed here. But I am still not sure how to fix it without writing my own get. -
Saving images uploaded through ImageField
I am trying to set up a webapp that accepts image uploads from a user, using ImageField, but I cant seem to figure out how to save the uploaded image. My media folder is empty even though there doesnt seem to be any errors. Went through a lot of tutorials to no avail. I get the basic concept, create a form, model, set media in settings.py, handle upload in views, and I am getting a working view with a image upload form, but uploading an image does not save. settings.py MEDIA_URL = '/media/' MEDIA_ROOT = os.path.join(BASE_DIR, 'media') urls.py urlpatterns = [ path('embed/', embed, name = 'embed'), path('success', success, name = 'success'), ] if settings.DEBUG: urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT) forms.py class imguploadform(forms.ModelForm): class Meta: model = imgupload fields = ['title', 'image'] models.py class imgupload(models.Model): title = models.CharField(max_length = 20) image = models.ImageField(upload_to="media/images/", default = None) def __str__(self): return self.title views.py def embed(request): if request.method == 'POST': form = imguploadform(request.POST, request.FILES) if form.is_valid(): newimg = imgupload(title=request.POST['title'], image=request.FILES['image']) newimg.save() return redirect('success') else: form = imguploadform() return render(request, 'webapp/imgupload.html', {'form' : form}) def success(request): return HttpResponse("Successfully uploaded") Another thing to note, the admin panel does not show the image model -
Custom Dependent Dropdown in Django
I am trying to implement two dropdowns in my registration page with custom fields that prompt a user to select their phone brand and the specific model of their phone. I want to have the phone model dropdown to be dependent of the phone brand dropdown. In other words, if I select that I have an Apple phone, the phone model dropdown should only give me the options Iphone 6, Iphone 7, Iphone 8, etc. So far I have not been able to discover how to do a custom dependent form so I tried starting small and doing one regular dropdown. Unfortunately, I was also unable to do that. To add the regular dropdown I added the following to my models.py from django.db import models PHONES = ( ('samsung','SAMSUNG'), ('iphone', 'IPHONE'), ('oneplus','ONEPLUS'), ('lg','LG'), ) class Phones(models.Model): phone = models.CharField(max_length=6, choices=PHONES, default='iphone') And then adding the following to forms.py from django import forms from django.contrib.auth.forms import UserCreationForm from django.contrib.auth.models import User from main.models import Phones class NewUserForm(UserCreationForm): email = forms.EmailField(required=True) class Meta: model = User, Phones fields = ("username", "email", "phone", "password1", "password2") def save(self, commit=True): user = super(NewUserForm, self).save(commit=False) user.email = self.cleaned_data["email"] if commit: user.save() #saves to db return user … -

Concurrent Process Logging in Django
I'm working on a Django-based application that needs to write to a logfile from multiple processes. I've looked at the idea from this answer which details the approach used in the multiprocessing-logging package here. However, I can't seem to find a way to implement it in Django in such a way that avoids throwing this error: PermissionError: [WinError 32] The process cannot access the file because it is being used by another process: /logfile.log -> /logfile.log.1 In my MyApp/settings.py file I have the handler for the logfile configured as such: 'handlers': { .... 'logfile': { 'level': 'DEBUG', 'class': 'logging.handlers.RotatingFileHandler', 'filename': BASE_DIR + "/logfile.log", 'maxBytes': 50000, 'backupCount': 2, 'formatter': 'standard', }, 'console': { 'level': 'INFO', 'class': 'logging.StreamHandler', 'formatter': 'standard' }, }, 'loggers': { 'django': { 'handlers': ['console'], 'propagate': True, 'level': 'WARN', }, 'django.db.backends': { 'handlers': ['console'], 'level': 'DEBUG', 'propagate': False, }, 'MyApp': { 'handlers': ['console', 'logfile'], 'level': 'DEBUG', }, In the part of the application that runs multiple processes, I have the logging configured as such: # Ref: https://github.com/jruere/multiprocessing-logging import logging from multiprocessing_logging import install_mp_handler LOG = logging.getLogger('MyApp') install_mp_handler() ... if __name__ == '__main__': ... with Pool() as pool: pool.map(func, iterable) Notes: This logs to the console fine but seems to … -
How to query to calculate the quantity times the price using Django ORM
I would like to know how to get the total price of: quantity times price in Django ORM, and which variable to use for template to view the value? The post is submitted successfully, but cannot get the total price: this is what I have in my views.py: context={ "tickets": Ticket.objects.all(), "total":Ticket.objects.filter(purchaser=User.objects.get(id=request.session['user_id'])).aggregate(total_cost=Sum(F('price')*F('quantity'), output_field=FloatField()) } return render(request, 'first_app/confirmation.html', context) This is in my models.py: from django.db import models from django.db.models import Sum, Aggregate, F class User(models.Model): first_name=models.CharField(max_length=100) last_name=models.CharField(max_length=100) email=models.CharField(max_length=100) password=models.CharField(max_length=100) created_at=models.DateTimeField(auto_now_add=True) updated_at=models.DateTimeField(auto_now=True) class Ticket(models.Model): venue=models.CharField(max_length=100) quantity=models.PositiveIntegerField(default=1) price=models.DecimalField(default=25.00, max_digits=10, decimal_places=2, null=True, blank=True) loop=models.CharField(max_length=100) purchaser = models.ForeignKey(User, related_name="purchases", on_delete=models.PROTECT) created_at=models.DateTimeField(auto_now_add=True) updated_at=models.DateTimeField(auto_now=True) How do you query ORM to get the total quantity * price? Should that query be included before or after you do the "ticket" key in context? Should that query be added the Ticket model field? Each each is hardcoded as $25.00 as shown in models. Thank you, I'd greatly appreciate it! -
Using SQLite3 with Django 2.2 and Python 3.6.7 on Centos7
I am moving my Django code from 2.1.7 directly to the new Django 2.2. The only problem I encountered in my Centos7 development environment was that my local development database (sqlite3) version was incompatible using my Python 3.6.7. The error I was getting from "manage.py runserver" was: django.core.exceptions.ImproperlyConfigured: SQLite 3.8.3 or later I am unable to use another version of Python because this is the maximum supported by AWS elasticbeanstalk. The Python 3.6.7 seems to come with sqlite module of version: >>> import sqlite3 >>> sqlite3.version '2.6.0' >>> sqlite3.sqlite_version '3.7.17' >>> I use a seperate development account on my local Centos7 workstation and issue pipenv shell to begin my code development and IDE. The only workaround I've found is to manually download SQLite3 autoconf version 3.27.2 and manually compile into that development account home folder using the following commands: wget https://www.sqlite.org/2019/sqlite-autoconf-3270200.tar.gz gzip -d sqlite-autoconf-3270200.tar.gz tar -xvf sqlite-autoconf-3270200.tar cd sqlite-autoconf-3270200/ ./configure --prefix=/home/devuser/opt/ make make install Following that, I have modified my .bashrc to reflect the following: export LD_LIBRARY_PATH="${HOME}/opt/lib" This seems to do the trick when I log back into my devuser account. My app seems to run correctly using my local development database. Python 3.6.7 (default, Dec 5 2018, 15:02:05) [GCC … -

Slow loading Django Admin change/add
I'm making a classic single view application, mapping multiple datasources. Django-admin is paginated so there's no impact when I view my list, the problem is when I want to change/add it is .

The difference between SessionStore and Session object in Django
I have searched online and carefully read Django documentation, but still didn't find an answer. The documentation doesn't really explain when to use SessionStore vs. Session. I had this question when I was trying to modifying request.data in a form. I need to manually modify the session object in database to save the changes made in form. Though I am not sure whether that change is only saved to database or also in cache? I have set the SESSION_ENGINE to both cache and database backend. The cache is RedisCache. CACHES = { "default": { "BACKEND": "django_redis.cache.RedisCache", "LOCATION": "redis://127.0.0.1:6379/1", "OPTIONS": { "CLIENT_CLASS": "django_redis.client.DefaultClient", } } } SESSION_ENGINE = "django.contrib.sessions.backends.cached_db" If I modify the SessionStore object in form, is still cached? Or is it only saved to database? I would really appreciate if anyone can help me gain a solid understanding of SessionStore and Session objects. -
How to change an existing variable in a django template
Newish to Django here and need some assistance. I have a bool variable empty=True. I passed the variable through views to my template successfully. In the template I have a while loop that includes an if/else statement. I need to be able to change my variable to False if it meets a condition in the if statement. Once I'm out of the loop there is another if/else statement to check in empty is True. I can't seem to figure out how to change a variable in the template. I did try a with statement to change the variable but it didn't work correctly for me because I have to end the with statement before the loop ends. Once the with statement ends, the variable reverts back to its' original value -

Saving Pillow Images from PDF to Google Cloud Server
I am working on a Django web app that takes in pdf files and does some image processing to each page of the pdfs. I am given a pdf and I need to save each page into my google cloud storage. I am using pdf2image’s convert_from_path method to generate a list of Pillow Images for each page in the pdf. Now I want to save these images to google cloud storages but can’t figure it out. I have successfully saved these Pillow images locally but I do not know how to do this in the cloud. P.S. I did not include code because I do not think you will benefit from reading my code since I am asking more about how to do it.
