What is the best way to transition from imp to importlib for CloudLinux Passenger WSGI files?
I am looking for the best way to transition from imp to importlib with my passenger_wsgi.py file using importlib as recommended by pylint. My passenger file looks like this: import imp import os import sys sys.path.insert(0, os.path.dirname(__file__)) wsgi = imp.load_source('wsgi', 'core/wsgi.py') application = wsgi.application I have seen some examples using importlib.utils.find_spec(path) and some using importlib.machinery.SourceFileLoader('name','script') Does anyone have an example for their passenger_wsgi.py file that uses the newer method with importlib that would be the new standard they could share? -

How to get a QuerySet with type of a ForeignKey attribute in Django
I have a simple database model in Django that looks like: class Employee(Model): first_name = models.CharField(max_length=128) last_name = models.CharField(max_length=128) class PrizeDraw(Model): winner = models.ForeignKey( Employee, null=True, on_delete=models.SET_NULL, ) What I want now is a QuerySet of type Employee that contains all the winners of all PrizeDraws. I would have thought that to be fairly straightforward by something something like: def get_queryset(self): return PrizeDraw.objects.exclude(winner__isnull=True).values('winner') However, that doesn't actually return me what I want, instead it returns: <QuerySet [{'winner': (Employee1) }, {'winner': (Employee2) }, etc...]> Which makes sense according to the values() documentation it returns a Dictionary of values. But this doesn't work for me in the rest of the code I need, so I want to select only the second (i.e. value) part of the key-value pair and return that as a QuerySet that just looks like <QuerySet[Employee1, Employee2, etc...]>. How can I select the right value as to get that desired QuerySet? -

After a click to lunch button, I want to launch the process and I want to send to another page the path of results files to allow the user to download it. My problem is after clicking on lunch button and send data to the other page.

Django - How to access parent object for passing as URL primary key inside templates?
I have two Django models: class AP(models.Model): room = models.ForeignKey(Room, on_delete=models.SET_NULL, null=True) and class Room(models.Model): name = models.CharField(max_length=20, unique=True) I have passed an object of AP class as ap to the template. In the template, I am trying to create a hyperlink with ID of the room. I am creating hyperlink through the following line: <a href="{% url 'edit_ap' ap.room.id %}">{{ap.room.name}}</a> This is throwing the following error: Reverse for 'edit_ap' with arguments '('',)' not found. 1 pattern(s) tried: ['edit\\-ap/(?P<pk>[^/]+)/$'] The urls.py has the following matching pattern: path('edit-ap/<str:pk>/', views.edit_ap, name='edit_ap'), The hyperlink is working if the primary key is changed from ap.room.id to ap.room, which passes room.name as the primary key to the URL. However, I need to provide ap.room.id as the primary key. I believe it has to do with using two dots in the primary key. Can you please suggest how can I pass ap.room.id as primary key to my URL? Thank you. -

working with SQLSERVER database that doesn't have keys using DJANGO
I'm currently doing an internship at a company, they asked me to build an invoice management web app, the process is a little complicated. First I created the login page, home page and the core elements of every web app. I used PostgreSQL for this, but when I wanted to build the main functionalities of the app, I switched to a copy of their database, they are using SQL Server 2012 and the data is coming from an ERP. The problem is when I have connected to database and use inspect DB to get the tables, I discovered that all the tables in the database don't have a Primary Key or Foreign Key. I asked the IT responsible about this and he told me that the ERP is stocking the data without any keys, it uses another method. I would really appreciate it if someone could help me out of this issue. -

Different methods of Django User model
I have been using Django for 4 5 months now and i have been implimenting users by importing the user class like this example 1: from django.db import models from django.contrib.auth.models import User class Posts(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE) post_name = models.CharField(max_length=150) desription = models.CharField(max_length=200) image = models.ImageField(upload_to="images/uploads") def __str__(self): return self.desription and i have seen some people use the user model like this : example 2: class Recipe(models.Model): user = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE) name = models.CharField(max_length=220) description = models.TextField(blank=True, null=True) directions = models.TextField(blank=True, null=True) timestamp = models.DateTimeField(auto_now_add=True) updated = models.DateTimeField(auto_now=True) active = models.BooleanField(default=True) and also like this : example 3: author = models.ForeignKey(get_user_model()) now I have used both example 1 and example 2 for my projects and to mess around in my free time and both seem to work fine , I am wondering what would be the use cases for these different methods and also is there any pros or cons to these methods of using the User Model? -

And data = json.loads(request.body) and following data are same data = [{'quantity': 2, 'service_id': 1, 'price': 2}, {'quantity': 2, 'service_id': 1, 'price': 2}, {'quantity': 2, 'service_id': 1, 'price': 2}] @api_view(['GET', 'POST']) @csrf_exempt def create_order(request, *args, **kwargs): if request.method == 'POST': now = datetime.date.today() order = Order.objects.create(date=now) order.save() orderid = order.id order_id = orderid data = json.loads(request.body) print('data = '+ str(data)) price = request.session.get('price') print('Price = ' + str(price)) quantity = request.session.get('quantity') print('quantity ' + str(quantity)) service_id = request.session.get('service_id') print("Service id = "+ str(service_id)) orderitemslist = [int(v) for lst in data for k,v in lst.items()] quantity = orderitemslist[1] service_id = orderitemslist[2] price = orderitemslist[3] for item in orderitemslist: orderitemcreate= OrderItem.objects.create(order_id_id=order_id, quantity=quantity, service_id_id=service_id, price=price) orderitemcreate.save() return Response({"data created"}) else: order_qs = models.Order.objects.all().values_list() OrderItem_qs = models.OrderItem.objects.all().values_list() return Response({"Order":str(order_qs),"OrderItem":str(OrderItem_qs)}) I want to store data in db like if there are three [{'quantity': 2, 'service_id': 1, 'price': 2}, {'quantity': 2, 'service_id': 1, 'price': 2}, {'quantity': 2, 'service_id': 1, 'price': 2}] dictionaries in list. The loop should create 3 Orderitem and store each value in table. But it creates 9 orderitems because there are 9 colums(1 dict has 3 col) 3 dicts = 9 cols … -

Django, despite of setting request.method to POST it's GET in view
I'm making Django app and I have an issue, I've never had problem with before. As always in form view, I'm checking if request.method == 'POST' but somehow it returns False, My code looks like that: def recipe_create_view(request): context = {} form = RecipeForm() IngredientFormset = formset_factory(IngredientForm) formset = IngredientFormset() print(request.method) # prints GET if request.method == 'POST': form = RecipeForm(request.POST) formset = IngredientFormset(request.POST) if form.is_valid(): if formset.is_valid(): form.save() print("made a recipe") for form in formset: child = form.save(commit=False) child.recipe = parent child.save() print("made an Ingredient") return redirect('index') else: print("formset is not valid") else: print("form is not valid") else: print("request method is not correct") # I can see it every time in console context['form'] = form context['formset'] = formset return render(request, 'recipes/create_recipe.html', context) create_recipe.html <form method="POST"> {% csrf_token %} <label>recipe</label> <p>{{form}}</p> <label>ingredients</label> {% for form in formset %} <ul> <label>name</label> <li>{{ form.name }}</li> <label>quantity</label> <li>{{ form.quantity }}</li> </ul> {% endfor %} <div> <input type="submit" value="submit" class="button-33" role="button"> </div> </form> Where is the issue, it so annoyoing. I have already checked plenty of articles and nothing helps
