Why is this if statement not working in Django?
I'm just trying to run an if statement in html using django in the {% %} things. The statemnet is {% if listing in watchlist %}. Even though the listing is in watchlists, it doesn't make the if statement true. I used {{ }} to see what watchlist and listing are. for {{ watchlist }} I got: <QuerySet [<Watchlists: 15: Dan1308 has added 3: The Bus (yes the cool airplane), starting at 3000 to watchlist>]> for {{ listing }} I got: 3: The Bus (yes the cool airplane), starting at 3000 here's my views.py: def listing(request, NewListings_id): user = request.user listing = NewListings.objects.get(pk=NewListings_id) comments = Comments.objects.filter(listing=listing) watchlist = Watchlists.objects.filter(user=user) return render(request, "auctions/listing.html", { "listing": listing, "comments": comments, "user": user, "watchlist": watchlist }) and here's my models.py: class Watchlists(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE) listing = models.ForeignKey(NewListings, on_delete=models.CASCADE) def __str__(self): return f"{self.id}: {self.user} has added {self.listing} to watchlist" So, why is it not working? -
Unable to display JsonResponse in Django web project
I am working on a django project. I want to display the result of a query with JsonResponse, but I can only get the raw data, rather than the colourful Json response. Here is my code views.py from django.shortcuts import render from django.db import connection from django.http import JsonResponse import json # Create your views here. def index(request): return render(request, 'AppTPCC/index.html') def result(request): search_string = request.GET.get('name', '') query = 'SELECT * FROM item WHERE i_name ~ \'%s\'' % (search_string) c = connection.cursor() c.execute(query) results = c.fetchall() result_dict = {'records': results} return render(request, 'AppTPCC/result.html', result_dict) def query(request): query = """ SELECT w.w_country, SUM(s.s_qty) FROM warehouse w, stock s, item i WHERE i.i_name = 'Aspirin' AND i.i_id = s.i_id AND w.w_id = s.w_id GROUP BY w.w_country; """ c = connection.cursor() c.execute(query) results = c.fetchall() return JsonResponse(results, safe=False) urls.py from django.urls import path, re_path, include from . import views urlpatterns = [ re_path(r'^$', views.index), re_path(r'result', views.result), re_path(r'query', views.query, name='query'), ] Then when I type http://127.0.0.1:8000/AppTPCC/query in my browser, I can only get the raw data type.

object not being saved on database while using Ajax on django
I have this form that uses ajax on post method when saving new todo object on database and it works fine. When I add new entry on the form, it is being saved on the database and displays the new entry on the end user. However, I made a code that whenever I clicked those tasks below(the whole div), (Grocery, eat snack, etc see the picture for reference), the object's completed attribute should be True(it means the end user is done doing the task) and the texts should have a line-through on it. But, the completed attribute of each tasks listed below is not being saved as True on the database after every time I add a new entry and click the tasks, it only adds a line-through style on text, It will only be saved when I refresh the page and then click on those tasks again. in short: working: adding new entry, it displays new entry on end user without refreshing the page not working: clicking the task to make the completed attribute True after adding new entry. it only adds line-through style on each texts. (This will work ONLY if I refresh the page and then click … -
Nested writable serializer to process flattened normalized request data
I have a nested writable serializer. class GamerSerializer(serializers.ModelSerializer): account= AccountSerializer() document = DocumentSerializer() class Meta: model = Gamer fields = [ 'chosen_game', 'gamer_experience' ] This serializers is supposed to create Account object, a Gamer object related to Account as well as Document object related to Gamer. By default the nested serializer always accepts nested objects as data like this: serializer = self.get_serializer(data= { account: {...acount}, document: {...document}, chosen_game: "Minecraft", "gamer_experience": "1 year" } ) but I want the serializer to accept normalized flattened data( we assume that names of the model attributes do not overlap). Like this : serializer = self.get_serializer(data= { account_name: '', account_type:'', document_name: '', document_file: '', chosen_game: "Minecraft", "gamer_experience": "1 year" }) How can I achieve this result ? -

ebay python SDK with django - config file not found when addietm function is called through views.py, works otherwise
I'm building a django project where, in my views.py, I'm trying to call a function from another .py file in the same directory, which makes an api call to ebay.

django-cors-header problem with authorization cookies
I am using Django base authorization to protect specific routes of my API (using @login_required decorator), and Insomnia to test them out. Using Insomnia I can login using my ```api/auth`` route and then access to every protected route of my APIs. The problem comes with React: I have my React app running on localhost:3000 and my Django APIs on localhost:8000. When I log in though the login page (made with react and react-router-dom) it just works. But after that, if I open the HomePage (which fetches data from a login_required route) I get a 404 response ( which is caused by @login_required ). I tought that the problem was because of fetch and cookies, But I can't figure out a way to solve it. It seems like Insomnia automatcally stores the cookie returned by api/login but the same doesn't happen with react. I've also already tried to set credentials to include and same-origin in my login fetch. Did someone already experienced this problem?

Creating a single API with models which dont have direct relationship with each other
I have these 3 models. Among these 3 models, Flightdetails and Passenger are in relationship with the third model Booking. But the 1st and the 2nd model doesnt have any relationship. And in the frontend I have a form like that for the booking. What I want to do is create an POST API from passenger model where user can submit the passenger's info and it is booked. BUt what my senior is demanding is that in the same post api, I should also have the flight id( primary key) request, so that when I submit the form or book, it (the object) should also have its own flight id. I hope I explained well. class FlightDetails(models.Model): Flight_Name = models.CharField(max_length=200) Aircraft_name = models.CharField(max_length=200) Destination = models.CharField(max_length=200, verbose_name = "To") def __str__(self): # return self.Flight_Number return 'Flight({})'.format(self.id) class Passenger(models.Model): First_name = models.CharField(max_length=200, unique=True) Last_name = models.CharField(max_length=200, unique=True) Gender = models.CharField(max_length=50) Nationality = models.CharField(max_length=200, unique=True) Passport_No = models.CharField(max_length=200, unique=True) Passport_Exp_Date = models.DateField(blank=False) Contact_Number = PhoneField(help_text='Contact phone number') Email = models.EmailField(max_length=200, unique=True) # Customer_id = models.CharField(max_length=50) def __str__(self): return (self.First_name, self.Contact_Number) class Booking(models.Model): # Book_Id = models.CharField(max_length=50) flight_number = models.OneToOneField(FlightDetails, on_delete = models.CASCADE) Booking_Date = models.DateField(default= True, verbose_name = "Booking Date(dd/mm/yy)") customer_name_and_phone = … -
Deploy Django 1.7 application to Apache2 with WSGI
I am trying to deploy an old Django application (1.7) to the Apache2 server on Debian. I am finally able to run the app with ./manage.py runserver but I had no success in getting the mod-wsgi working. I've never wrote a server side application in Python so please forgive me if I am missing something obvious. These are the steps I followed Everything I tried is with /usr/bin/python which is 2.7 - I know, I should be using virtuelenv but I didn't want to add even more complexity to the while thing (since I am not familiar with it) installed mod-wsgi with apt-get install libapache2-mod-wsgi Add following config to the /etc/apache2/mods-enabled/wsgi.conf Apache2 restart <IfModule mod_wsgi.c> WSGIScriptAlias / /home/rosasystem.pl/public_html/rosasystem/rosasystem/wsgi.py WSGIPythonHome /usr/bin/python WSGIPythonPath /home/rosasystem.pl/public_html/rosasystem LogLevel warn <Directory /home/rosasystem.pl/public_html/rosasystem/rosasystem> <Files wsgi.py> Order deny,allow Require all granted </Files> </Directory> </IfModule> Since then, I keep getting this error message in the error.log - most of the stuff I've googled suggest that there is a Python version discrepancy between mod-wsgi and system/virtualenv Python version which in this doesn't make sense because everything is Python 2.7.

How to place a button in each row of table in django management form
In my Django application, I have a form with Parent/Child model objects laid out using loop. To dynamically add child form instances, I am using Django dynamic formset. Every thing works fine including saving of user inputs without hassle. So far, so good. However, now my user wants that I place one button before a particular field (spl_instructions) in each of the dynamically rendered rows (of fields). The instant field spl_instructions (of the child table) is a CharField of 255 chracters and is being rendered as Textarea in the page. The "button" is intended to be used to open the field spl_instructions if and when there is a need to enter text in the field. This route is being taken to conserve space. models.py class ProductAssy(models.Model): prod_assy_id = models.AutoField(primary_key=True, ...) prod_assy_num = models.CharField(max_length=24, ...) prod_assy_type = models.ForeignKey(MaterialType, ...) short_text = models.CharField(max_length=55, verbose_name="Description") # ... Rest of the fields class BillOfMatlItems(models.Model): bom_item_id = models.AutoField(primary_key=True, ...) prod_assy_id = models.ForeignKey(ProductAssy, ...) short_text = models.CharField(max_length=55, verbose_name="Description") spl_instructions = models.CharField(max_length=255, ...) # ... Rest of the fields forms.py class CreateProdAssyForm(forms.ModelForm): class Meta: model = ProductAssy fields = (...) class CreateAssyBomForm(forms.ModelForm): class Meta: model = BillOfMatlItems fields = (...) widgets = { 'short_text': forms.TextInput(attrs={'style': 'width:300px; text-align:right;'}), …
