How i can manage Chat system between my React(front-end) and Django (back-end)
I am working on a chat application, in which I'm gonna use React for the Front-end and Django as the back-end. Note: Both are on different servers. Everything will work through the APIs. I want to know how I can establish a connection between React and Django so I can get real-time messages and display them to the user. Should I use socket.io-client in my React app and Django-channels in my Django app.??? or is there any other way to do this?? And Instagram and other Companies that are using these both stack, how they are doing this stuff??? Please answer ... Kind Regards, Huzaifa -
Error while changing a Char field to Array Field in Django
I am trying to change a existing CharField in a django model (it also allows null and contains null values in db currently) now I am trying to change it to an Array Char Field, but it throws the below error "django.db.utils.IntegrityError: column "tags" contains null values" From tags= models.CharField(max_length=255, blank=True, null=True) To tags = ArrayField(models.CharField(max_length=255, blank=True, null=True)) I have selected option 2 while before running migrate -
Django Redirect: No errors, but no redirect
I POST some data via an HTML form using AJAX to modify data in my database. The data is successfully modified by executing stored procedures on the DB. Final line of the view.py function call is return redirect('Home'). The redirect is successfully executing, but I am not being redirected. I can overcome this by adding window.location.href = 'http://127.0.0.1:8000/ in the success function of the AJAX call. The problem is, I want to use messages.success(request, 'Data Successfully Updated'), which only appears after refreshing the AJAX-originating redirect. Is there a reason why return redirect('Home') is not working here, and is there a way to overcome this? Home is the name of my path in urls.py [06/May/2021 17:23:52] "POST /search/ HTTP/1.1" 302 0 // submitting changes to database [06/May/2021 17:23:55] "GET / HTTP/1.1" 200 4750 // The page I am intending to redirect to Ajax Call function updateCards(){ ajaxUpdCard().done() function ajaxUpdCard() { return $.ajax({ type: 'POST', url: '', data: {csrfmiddlewaretoken: window.CSRF_TOKEN, Action: 'Card', CardID: $('#currentCardID').val(), BCard: $('#sr-bad_card').val(), CNum: $('#sr-card_number').val(), CPin: $('#sr-pin_number').val(), Bal: $('#sr-balance').val()} }) } } views.py if request.method == 'POST' and request.POST['Action'] == 'Card': cardID = request.POST['CardID'] Bcard = int(request.POST['BCard']) CNum = int(request.POST['CNum']) CPin = int(request.POST['CPin']) if request.POST['CPin'] != '' and request.POST['CPin'] … -

Conditionally authenticate users to DRF view
I have a DRF view as such: class DocumentsView(generics.ListCreateAPIView): permission_classes = () authentication_classes = () # I typically enforce authentication with # authentication_classes = (JWTCookieAuthentication,) def list(self, request): pagination_class = None if request.user.is_authenticated: ... return protected data ... else: ... return generic data ... I want to allow both users sending a valid token and those not sending a valid token to both get a response from this endpoint. However, request.user.is_authenticated returns False, even when a valid token is sent (I understand why). How can I try to authenticate the user, but still allow them to proceed even if not presenting a token? Or is better practice to not have the same view to authenticated an unauthenticated users? -

Django date format by an user
I'm writing a Django application that requered to give the user the ability to create his own time format, over an API (problay GraphQl). I've figure out the following way, but it seems to be really hard solution for relativlly small problem. class Formatter(models.Model): ... class DateLetter(models.Model): formatter = models.ForeignKey(Formatter, related_name="letters", on_delete=models.CASCADE) index = models.IntegerField(db_index=True) letter = models.CharField(max_length=255, unique=True, choices=LetterChoices.CHOICES, default=LetterChoices.Y) And after that, just going with some sort of loop to get the instance as a date format (%Y-%m-%d) etc. -
Django multiple user roles using AbstractUser without username field
I am trying to build an electronic information system for one teacher and students. Using the tutorial shown here: https://simpleisbetterthancomplex.com/tutorial/2018/01/18/how-to-implement-multiple-user-types-with-django.html , in my models.py I have implemented the student and teacher models this way: class User(AbstractUser): is_student = models.BooleanField(default=False) is_teacher = models.BooleanField(default=False) class Student(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE, primary_key=True) f_name = models.CharField(max_length=20) l_name = models.CharField(max_length=30) parent_tel_numb = models.CharField(max_length=13) parent_f_name = models.CharField(max_length=20) parent_patronimic = models.CharField(max_length=30) parent_l_name = models.CharField(max_length=30) group = models.ForeignKey(Group, to_field='id', on_delete=models.SET_NULL, blank=True, null=True) class Teacher(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE, primary_key=True) For my application I would like to exclude the username field both for Teacher and Student models. Instead, I want to use email as username. I have previously tried to do it this way, modifying the User model: class User(AbstractUser): is_student = models.BooleanField(default=False) is_teacher = models.BooleanField(default=False) username = None email = models.EmailField(unique=True) USERNAME_FIELD = 'email' REQUIRED_FIELDS = [] However, after that, when I tried to create a superuser in the terminal, the username field was omitted during the creation of superuser and after submission of email and password, I got an error, saying the username field is absent. How do I deal with this issue? -

Add wordlist.txt in exclude query
I am building a BlogApp and I am trying to add wordlist.txt at the place of exclude('wordlist.txt') What i am trying to do :- I build a feature of exclude posts according to words, For Example :- If a post contains word "Bad" then exclude that post like :- from django.db.models import Q posts = Post.objects.exclude(Q(description__contains='bad') & Q(description__contains='bad1')) BUT i am trying to exclude hundreds of words at the same time AND when i add all of them in this way then it will be very lengthy AND i don't want that, So i think I can make a file named wordlist.txt and put all my words that i want to exclude then put the path of wordlist.txt in exclude query so i do not have to write lengthy exlcude words in the query. For example :- posts = Post.objects.exclude(description__contains=wordlist.txt) ( Above example is just to explain, what i am trying to do ) I have no idea how can i do it . Any help would be Appreciated. Thank You in Advance -

Bulk update with different values in django 1.11
I have been reading the official documentacion of django 1.11 about bulk updating. My problem is that I have only seen how to update the fields for ALL the query objects. What I need is a bulk update but with different values, depending on a condition. Let me write an example. Let's say I have the following model: class A(models.Model): key = models.ForeignKey(SomeOtherModel, db_index=True) value = models.FloatField(blank=True, null=True, default=None) As you can see, the field_definition points to another model. What I want is to mass update the objects of a query of the model A based on that value. Something like this: A.objects.filter(key__id__in=[1,2,3]).update(value_for_id_1="1", ..., value_for_id_n="n") The only thing I have seen so for is this syntax: A.objects.filter(key__id__in=[1,2,3]).update(value="1") Any idea if this is even possible? How can I make this query efficient? -
The best way to get data from another database and refresh it every few seconds in Django
I am wondering what is the best way to get data from another database (on the same server but it is part of different application) and refresh it every few seconds. I want to let user to choose from a select form that contains all the objects with specific status field. I want to use pyodbc (I'm using MySQL for both of databases), run a simple select (E.g. SELECT Index, Name FROM Table WHERE Status = 'OPEN'), create object for every row if it doesn't already exist in Django database: cursor.execute("SELECT Index, Name FROM Table WHERE Status = 'OPEN") for row in cursor: try: order = Order.objects.get(index=row[0]) except Order.DoesNotExist: Order.objects.create(index=row[0], name=row[1]) but my question is- when should i run it? Time it in a loop and do it every few seconds somehow? Or should I just do it every time user requests for a view with select form that contains these objects. What is the correct approach? -

running some Dash-Plotly apps inside a Django app similar to PaaS (platform as a service)
I have a challenge and I would be grateful if you could give me some clue... I want to run some Dash-Plotly (a framework based on Flask) applications inside a Django app. I know Dash has a framework called django-plotly-dash but what I want is a Django app that our developed Dash(aka Flask) apps can easily be imported and run. In other words, I want to make Django app a Paas (Platform as a Service) and other Dash/Flask apps can be imported in Django dashboard/(our developed page) and can be accessible from the Django app. Some idea may be using Docker containers but is also has some challenges and we want to seek the most optimal solution. is there any idea??? -

How to return back just queryset objects from middleware?
I'm not sure being I understand what does Middleware will help me in Django do. but if it will help me to make some help for request/response to appear globally so that, I really need it. based on that, I read a little bit more explanations and tutorials about Middleware also, I read some docs in Django middleware hence, wanted to use a request which will return an object from query set based on this request something like you will see underneath: Order.objects.get(user=request.user, in_progress=True) I confused between the two next function names which handle the response in Middleware of Django: process_template_response and process_response the problem is I need to return back the objects which will be handled in the views.py file in Django by one of these response function. I read an old doc that supports Django 1.8 and see the difference between that two functions in response as following: the process_template_response as the documentation mentioned: is called just after the view has finished executing, if the response instance has a render() method, indicating that it is a TemplateResponse or equivalent. but when I read about process_response despite is called it before request as I understand, I figured out that … -

But when I want to do a post request to this ViewSet Its shows this error: { "detail": "Method \"POST\" not allowed." } What is the problem?
