Django: Is annotating twice with same lookup a bad practice?
I want to annotate a queryset to filter with this annotation. In some cases, my queryset might already have the annotation set. What happens if I annotate my queryset twice (same lookup, and same values): Does it perform unnecessary jobs on the DB side? Example: queryset = MyModel.objects.annotate(my_annotation=F("some stuff")).filter(my_annotation="some other stuff") # a bit later queryset = MyModel.objects.annotate(my_annotation=F("some stuff")).filter(my_annotation="some other stuff") If yes, how can I check the already annotated lookups without evaluating my queryset? -
Add another and remove is not showing django formset is anythng i missed in html
I have created a formset, which is showing in html but its not showing add another or delete links. When I check the console. I am getting an error like this also, custom.min.js:1 Uncaught TypeError: $(...).slimScroll is not a function at HTMLDocument.<anonymous> (custom.min.js:1) at c (jquery.min.js:3) at Object.fireWith [as resolveWith] (jquery.min.js:3) at Function.ready (jquery.min.js:3) at HTMLDocument.H (jquery.min.js:3) Is this happening because of above error or i missing something in my code.

Passing request to messages.error in TemplateView Class
I'm replacing my view defs with classes. I first tried a View: class DiscoverView(View): def get(self, request): page_name = 'discover' try: page = Pages.objects.get(name='discover') except (Pages.DoesNotExist, Pages.MultipleObjectsReturned): messages.error(request, 'Page is not configured: ' + page_name) return redirect('MS_Home') context = { 'page': page, } return render(request, 'base/discover.html', context) This worked fine. I next decided to do a TemplateView with an intervening parent class to try to stay dry. class PageView(TemplateView): def get_context_data(self, *args, **kwargs): context = super().get_context_data(**kwargs) page_name = kwargs['page_name'] try: page = Pages.objects.get(name=page_name) except (Pages.DoesNotExist, Pages.MultipleObjectsReturned): messages.error(self.request, 'Page is not configured: ' + page_name) return redirect('MS_Home') context['page'] = page return context class AboutView(PageView): template_name = 'base/about.html' def get_context_data(self, *args, **kwargs): kwargs['page_name'] = 'about' context = super().get_context_data(**kwargs) return context The normal path works. When the exception is thrown, it dies on the message.error: context must be a dict rather than HttpResponseRedirect. If I take out self.request in the messages.error() call, it complains about a missing parameter so I'm pretty sure it doesn't like self.request. How should I pass request to messages.error()? -

create_user not returning full user object of the newly created user
I am doing simply: user = User.objects.create_user(**data) print(user['id']) # user.pk dont work. If i do print(user), I see username of the newly added user.

Registration information not saving to database in Django
The registration part of the code does not work. After creating a new user it just redirects to the registration page and I can not figure out why.

Nginx isn't Serving Django Static Files Correctly Because of Trailing Slash
Currently, I have a Django web app being served by Gunicorn. Gunicorn does not serve static file requests so I am using Nginx in front of Gunicorn to serve static file requests. I am able to containerize the app fine with Docker and can successfully serve application requests but Nginx cannot serve the static file requests correctly because Django appends a trailing slash to static file requests. After running the Docker container with Django, Nginx, and Postgres services, I navigate to the home page of the web app and the first request is fine. HTTP Request 200 The rest of the incoming requests after navigating to the home page of the web app are static file requests all with 404 error codes. HTTP Request 404 The 404 error codes indicate that the server cannot find the static files but I can verify that my static files are stored in the correct location and are present. The 404 error codes are happening because Django static file requests append a trailing slash to the request. So, after reading the Nginx documentation, I discovered that Nginx treats all static file requests with trailing slashes as requests for directories and thus searches for an … -
Is sometimes single complicate query worse than two separate query?
I just came into the article on Django that says, when the amount of data is so huge it's better to split it and send them separately. I'm not really sure about this, because as far as I know, DBMS itself is so optimized and the networking is what causes the greatest portion of the latency. Are there really any cases like this? -
Django: Can't redirect to list page after clicking Submit button
Sorry for the long-ass post. I have a problem with my "update_fisher" view. It doesn't redirect to the "list_fishers" view after clicking the "Submit" button. What wonders me more is that "create_fisher" view uses the same html file for submitting forms, but it executes successfully. Here is the code for more details: fishers/views.py ... @ staff_member_required def create_fisher (request): form = FisherForm(request.POST or None) if form.is_valid(): form.save() form = FisherForm() return HttpResponseRedirect(reverse("fishers:list_fishers")) template_name = "fisher_form.html" context = {'form' : form} return render (request, template_name, context) @ staff_member_required def update_fisher (request, fisher_id): items = get_object_or_404(Fishers, fisher_id = fisher_id) form = FisherForm(request.POST or None, instance = items) if form.is_valid(): form.save() return HttpResponseRedirect(reverse("fishers:list_fishers")) template_name = "fisher_form.html" context = {'fishers' : items, 'form' : form} return render (request, template_name, context) ... fishers/urls.py from django.urls import path from . import views # this is responsible for the "namespace" in admin > urls.py app_name = 'fishers' # urlpatterns = [ path('', views.list_fishers, name = "list_fishers"), path('add_fisher/', views.create_fisher, name = "create_fisher"), path('update_fisher/<int:fisher_id>', views.update_fisher, name = "update_fisher"), fishers/templates/fisher_form.html {% extends "base.html" %} <title> {% block title %} Add/Update Information {% endblock %} </title> {% block content %} <div class = "page-header"> <h2> Fisher's Information </h2> </div> <form method … -

Retrieve Form Field Values With Ajax in Django
I have two forms. 1st form is CreateQuoteForm, which is used to create a Quote object - the user will fill this out first. The 2nd form is CreateProformaForm, which is used to create a Proforma object this will be completed second. I would like for the user to have the ability to select a Quote object from a select box and upon the click of a button, populate the CreateProformaForm fields with the data where there is overlap between the two models. Please see below for further illustration: models.py class Quote(models.Model): Name = models.CharField(max_length=30, null=True, blank=True) Shipment = models.ForeignKey(Shipment, null=True) Exporter = models.CharField(max_length=100, null=True, blank=True) QuoteNo = models.CharField(max_length=30, null=True, blank=True) class Proforma(models.Model): Name = models.CharField(max_length=30, null=True, blank=True) Shipment = models.ForeignKey(Shipment, null=True) Exporter = models.CharField(max_length=100, null=True, blank=True) QuoteNo = models.CharField(max_length=30, null=True, blank=True) Date = models.CharField(max_length=30, null=True, blank=True) Consignee = models.ForeignKey(Customer, null=True) As you can see, the models have similar fields. So after selecting the Quote in the selectbox, the fields Name, Shipment, Exporter, QuoteNo should populate in CreateProformaForm while Data and Consignee remain blank. Also to be clear - this should be an option for this user only, the form should be initialized blank. I am sure that this will … -
Uploading multiple csv files in Django using multiple file field form
I have tried uploading one csv file using Django file field form and it works well. However, switching the file field form into multiple file field form yields to an error when trying to read the csv file. What I initially tried for single csv file: in forms.py class UploadForm(forms.Form): file_field = forms.FileField(allow_empty_file = False) in views.py input_file = request.FILES['file_field'] data_set = input_file.read().decode('UTF-8') io_string = io.StringIO(data_set) next(io_string) model_list = [] for row in csv.reader(io_string, delimiter = ',', quotechar = "|"): #create Django model object based on the row and append it to model_list Sample_Model.objects.bulk_create(model_list) What I currently try for multiple csv files: in forms.py: class UploadForm(forms.Form): file_field = forms.FileField(allow_empty_file = False, widget=forms.ClearableFileInput(attrs={'multiple': True})) in views.py: input_files = request.FILES.getlist('file_field') for file in input_files: data_set = file.read().decode('UTF-8') io_string = io.StringIO(data_set) next(io_string) model_list = [] for row in csv.reader(io_string, delimiter = ',', quotechar = "|"): #create Django model object based on the row and append it to model_list Sample_Model.objects.bulk_create(model_list) I got a Stop Iteration error at the next(io_string) line. Upon browsing for its meaning and analysing the code, it seems data_set = file.read().decode('UTF-8') is the source of the problem as it does not work properly now. Thank you! -
Static files moved to a STATIC_ROOT but still none are being shown
Trying to deploy my site and everything is working fine except that the CSS in the admin page is non-existent. I have looked through all of the other posts where people have had this issue but i have already done the steps most of them forgot.

Why can't my user can't check their inbox?
So I am attempting to query and display messages between two users in an inbox. I am running into a problem where no messages are appearing for request.user's inbox. It's showing as empty when there are messages. However, when I go into an inbox for another user that my request.user has messaged while still logged in to request.user, I can see the messages from both parties there and displayed correctly. For the life of me, I don't understand why this is happening. Hell, request.user.username is passed through the template and my user's username actually prints.

Django user model. 1 admin account, 1 customer account with the same email and different password
Im trying to handle a use case where i have 2 roles. (admin , customer) There will be an admin portal and a customer portal (2 different login pages ). An admin can invite a customer An admin can be a customer as well , can invite himself into the customer portal An admin account must not share the same password as the customer account. Email is used as the unique field for both admin and customer account. For example : Admin account - customer@email.com /password1 Customer account - customer@email.com /password2 Solution 1: - Permission. Having 1 account with admin permission and customer permission. (This cant work to fit the bussiness use case) Based on this article: https://simpleisbetterthancomplex.com/tutorial/2018/01/18/how-to-implement-multiple-user-types-with-django.html Solution 2: - Creating 2 django projects. One for each user model since both accounts cant share password. The reason for separating into 2 projects is because resources such as session,login, logout will not be shared. So each portal(admin,customer) has their own resource. A create Customer API to allow admin to create a customer account in customer django project. A shared db to share related data This is the only way i can think of to handle the use case. Please let … -
How to test a Django+Celery application with multiple queues
I am wondering if it is feasible to write functional tests for a Django application using multiple Celery queues. For a single queue, I used the solution explained here, and it worked great. What I would basically want to do is the following: from celery.contrib.testing.worker import start_worker from django.contrib.staticfiles.testing import StaticLiveServerTestCase from mysite.celery import app class MyTestCase(StaticLiveServerTestCase): @classmethod def setUpClass(cls): super().setUpClass() cls.celery_worker1 = start_worker(app, perform_ping_check=False, queue="myqueue1") cls.celery_worker1.__enter__() cls.celery_worker2 = start_worker(app, perform_ping_check=False, queue="myqueue2") cls.celery_worker2.__enter__() @classmethod def tearDownClass(cls): super().tearDownClass() cls.celery_worker1.__exit__(None, None, None) cls.celery_worker2.__exit__(None, None, None) This code has two problems: I get the message /home/user/.local/lib/python3.7/site-packages/kombu/pidbox.py:74: UserWarning: A node named gen18391@Machine is already using this process mailbox! which leads me to think that multiple workers aren't handled properly. The "queue" argument isn't in the documentation and is likely not parsed at all. Consequently, the task sent to the second queue isn't being executed. -
What is the best practice for an internal API call in django
I've developed a chess API in django. I intend to develop a client for it as well. What would be the best practice for a client? Develop the client as another app in the same project in django, and perform internal API calls using requests(Is it better than calling the API externally performance wise? ) Develop the client as another app in the same project in django, and call the API's views using Django. (How would I do this, as the API expects JSON data in request) Develop the client as a standalone.
