django mod_wsgi and apache: module not found error
I am trying to move my django project to production using apache2 and mod_wsgi. I keep getting a wsgi_error "ModuleNotFoundError" in the apache logs. I run on ubuntu 22.04. After going through the various posts on the web I still am not getting anywhere, so I have now started from scratch by creating a new example django app. The same error occurs. PS, When I use "runserver" the django app displays fine in the browser. Also a simple wsgi "hello_world" app runs fine in apache. So I think the basic setup is fine. I have created a django test application "mytest" with django-admin startproject mytest The project is created in /home/user/myprojects/mytest, the group of all directories is www-data In mytest I have the usual django structure home/user/myprojects/mytest manage.py mytest asgi.py __init__.py settings.py urls.py wsgi.py The wsgi.py is: (The django/python runs in a virtual environment I found that I needed to add code to the wsgi to actually activate the virtual environment) """ WSGI config for mytest project.

Django - If statement with request.user
I have a problem with an if-statement. I just want to check on a page if the user who requests the listing page is the same one as the user who won the listing on that page. My view looks like this: def show_closed_listing(request, listing_id): closed_listing = InactiveListing.objects.get(id=listing_id) field_name = "winning_user" winning_user = getattr(closed_listing,field_name) message = False print(request.user) print(winning_user) if request.user == winning_user: print("This is good") message = "You have won this listing!" else: print("Not good") return render(request, "auctions/closed_listing.html", { "closed_listing" : closed_listing, "message" : message }) When I visit a page, signed in as Test2, when Test2 has won the listing, my terminal shows as follows: Test2 Test2 Not good As also can be seen here I don't get why request.user and winning_user look the same, but the if-statement is false? If needed, here is my model: class InactiveListing(models.Model): title = models.CharField(max_length=64) description = models.CharField(max_length=512, default="") winning_user = models.CharField(max_length=128) winning_price = models.DecimalField(max_digits=6, decimal_places=2, default=0.01) def __str__(self): return self.title -

for loop in django template input is only fetching the last one
I have a for loop in django templates and each iteration must save to two different instances. templates <p><label>{% trans "Payment Method" %}</label> {% for rs in shopcart %} <select class="input" name="payment" id="id_payment{{forloop.counter}}"> <option value="COD" data-description="Item 1" selected="selected">{% trans "COD" %}</option> <option value="Bank Transfer" data-description="Item 2">{% trans "Bank Transfer" %}</option> </select> <p id="description{{forloop.counter}}"></p> <script> $('#id_payment{{forloop.counter}}').change(function(){ var $selected = $(this).find(':selected'); $('#description{{forloop.counter}}').html($selected.data('description')); }).trigger('change'); </script> {% endfor %} views form = OrderForm(request.POST) if form.is_valid(): for rs in shopcart: d = Order() d.payment = form.cleaned_data['payment'] d.save() else: messages.warning(request, form.errors) form = OrderForm() context = { 'form': form } return render(request, 'Order.html', context) I wanted the payment choice to be made for each product in shopcart, but the last choice is fetched and given to all the products in the shopcart.

Django: get all objects with a defined set of related objects
Let's say we have a many2many relationship as follows: from django.db import models class Author(models.Model): name = models.CharField(max_length=100) class Book(models.Model): title = models.CharField(max_length=100) authors = models.ManyToManyField(Author, related_name="books") and now I have a known set of Authors: authors = Author.objects.filter(...) How can I get all the books that are authored by that exact set of authors? books = Book.objects.filter(X) what is X? Such that I have all the books authored by exactly that set of authors? I have tried, just because: books = Book.objects.filter(authors__in=authors) But nah, that returns the books to which any of those authors contributed it seems. I want the books that all of those authors contributed to and only those authors. Thus far, this has stumped me. -

Django url path regex: capturing multiple values from url
How do I capture multiple values from a URL in Django? Conditions: I would like to capture ids from a URL. The ids vary in length (consist of numbers only), and there can be multiple ids in the URL. Check out the following two examples: http://127.0.0.1:8000/library/check?id=53&id=1234 http://127.0.0.1:8000/library/check?id=4654789&id=54777&id=44 The solution may include regex. urlpatterns = [ path("", view=my_view), path("<solution_comes_here>", view=check_view, name="check_view"), ] P.S. all solutions I found on this platform and Django documentation only explain cases for capturing single values from the URL -

can I add my script/apis to my Django project? If so how can I do this
So I am building a Django web app, and I want to allow users to search for their desired crypto currency and then return the price. I plan on getting the price from coinbase or some other site that already presents this information. How would I go about this. I figure I would have to wrote the script to get the price under views.py. What would be the best approach? Can I add a web scrapping script that already does this to django? Or would I have to connect say coinbases api to my Django project. If so how do I do this? -

Django serializer not raising exception over model constraints
I have this dummy model from django.db import models class ChertModel(models.Model): username = models.CharField(gettext_lazy('username'), max_length=150, unique=True) o2 = models.CharField(gettext_lazy('username2'), max_length=150,editable=False, default='lllss') and with serializer class ChertSer(serializers.ModelSerializer): class Meta: model = ChertModel fields = ['username','o2'] note I have an instance with username='sd' and o2='434as' so when in the view I want to update the o2 fields which is supposedly editable=False it doesnt update it which is ok but the problem is that it doesnt raise exception over model constraints. note I have checked this configuration with editable=True and the serializer applies changes thus there is no problem with serializer. class ChertView(views.APIView): def get(self, request): lt1=ChertModel.objects.get(username='sd') print('1',lt1.o2) ser=ChertSer(instance=lt1, data={'username':'sd','o2':'newo2'}, partial=True) print(ser.is_valid()) ser.is_valid(raise_exception=True) ser.save() lt1=ChertModel.objects.get(username='sd') print('2',lt1.o2) since it would make problem of changes of user not applied to model instance without acknowledging it to user. so my question is how to detect the times the updating object is not applied due to model constraints? of course I can manually detect it by checking ser.data=={'username':'sd','o2':'newo2'} but is there any more formal or common way to handle this? -
