Django | Correct way to pass key identfiers to query sting
I was reading this Django doc: https://docs.djangoproject.com/en/3.0/topics/db/sql/#executing-custom-sql-directly It explains how to use params for preventing SQL-Injections and the documenation also just deals with paramaters, which in valid sql can become single quoted. Django simple escapes with single quotes by using: self.baz = "test" cursor.execute("UPDATE bar SET foo = 1 WHERE baz = %s", [self.baz]) becomes: b"UPDATE bar SET foo = 1 WHERE baz = 'test'" This shows that we cannot use the param argument for key identifiers like tablenames: cursor.execute("SELECT %s FROM %s", [column, table]) since single quotes are invalid sql query (back-ticks would be valid): b"SELECT 'id' FROM 'atablename'" This means that we can just pass data with string formatting e.g.: cursor.execute(f"SELECT {} FROM {}".format(column, table)) cursor.execute("SELECT "+column+" FROM "+ table) This way we have to take care ourselfs for sql-injections. Is there anything I am missing? How can I escape key identifiers in Django, so that there are no sql-injection possibilites? -

Following Django tutorial, "python manage.py migrate" doesn't create any django tables (MySQL, Pycharm)
In mysite.settings.py I have: DATABASES = { 'default': { 'ENGINE': 'django.db.backends.mysql', 'NAME': os.path.join(BASE_DIR, 'test'), #'NAME': 'test', 'USER': 'root', 'PASSWORD': 'password', 'HOST': 'localhost', 'PORT': '3306', }} When I run 'python manage.py migrate' in the PyCharm terminal, nothing happens, no error message etc. No new tables are created in the database specified. I tried two things for NAME as you can see. MySQL Server version 8.0.19 MySQL Connector/Python 8.0.19 Python version 3.8 In PyCharm I have package mysqlclient 1.4.6 installed. Any advice on how to find the problem? How to get an error message? Thank you -
Creating a waiting queue in Django Channels?
I am currently working on a "wait queue" application on my Django app using channels. I have a channel layer using Redis to handle the connections within a group. I am also using a model in my database to track the amount of users in the queue. My question is if there is an easier and more scalable way. Will there be any issues down the road with this? class ChatConsumer(AsyncWebsocketConsumer): @database_sync_to_async def get_waiting_room(self): return WaitingRoom.objects.all().count() @database_sync_to_async def add_to_waiting_room(self, name): return WaitingRoom.objects.create(name=name) @database_sync_to_async def remove_from_waiting_room(self, name): return WaitingRoom.objects.filter(name=name).delete() async def connect(self): self.waiting_list = 'waiting_list' await self.channel_layer.group_add( self.waiting_list, self.channel_name) await self.accept() async def receive(self, text_data): self.text_data = json.loads(text_data) await self.add_to_waiting_room(self.text_data['user']) users = await self.get_waiting_room() await self.channel_layer.group_send(self.waiting_list, { 'type': 'user_list', 'users': str(users) }) async def disconnect(self, close_code): await self.remove_from_waiting_room(name=self.text_data['user']) await self.channel_layer.group_discard( self.waiting_list, self.channel_name) users = await self.get_waiting_room() await self.channel_layer.group_send(self.waiting_list, { 'type': 'user_list', 'users': str(users) }) async def user_list(self, event): users = event['users'] await self.send(text_data=users) When a user connects, they are added to a group in the channel_layer (Redis) and accepts the connection, when my user clicks a button, it sends a request to the channel and adds them to the waiting room (My Django model), on disconnect, it removes Model instance and … -
HTTP 403 Even Im Logged In
i am trying to develop django/angular project and using base user model for django user. I tried to implement JWT auth in both side. On django side i am using rest_framework_jwt library. I checked the token flow from client-side to server-side. With a simple login page on angular i use my username and password for logging in. It's accepting my data and redirects me to the main page where i use a service to get "feed" data from server-side. In this step it gives me 403 error.

how to show or hide field of model after selected django admin choise field
The main logic of my project is to take a list of lessons. Lessons can be presented in the form of only a video format or in the form of a question and answer. My models for the video and the question are completely different. The problem is that I want to set the choice in the admin panel (video or question) and when the admin selects the video, fields for the video_id(foriegn key) should appear, another way must show question_id(from Question model, Foreign Key). Below showed my code(I removed unused fields): LESSON_CHOICES = ( (1, "video"), (0, "question"), ) class Lesson(models.Model): title = models.CharField(max_length=100, blank=True, default='') class VideoLesson(models.Model): video_url = models.TextField(default='') class Question(models.Model): text = models.TextField(default='') class LessonTask(models.Model): lesson_id = models.ForeignKey(Lesson, related_name='lesson_tasks', on_delete=models.CASCADE) order_num = models.IntegerField(unique=True) type = models.BooleanField(choices=LESSON_CHOICES, default=0) question_or_video_id = models.IntegerField(unique=True) I looked at this answer how to hide or show fields of model after clicked on choice field from admin in django but I did not understand anything and it is unlikely that it will help me. thnanks)) -

Django 3 confirmation email 'redefinition of group name' error

Django class based signup view with auto login not loging in the new user
I am developing an app in Django in which I am using the default User model and auth system built in Django. To the aforementioned model I have added (via foreign key) a Profile model to store some needed info. My problem comes when I try to create a new user using a class based view extending from generic.CreateView: class SignUpView(generic.CreateView): form_class = forms.RegistrationForm success_url = reverse_lazy('home') template_name = 'registration/signup.html' def form_valid(self, form): user = form.save() birthdate = form.cleaned_data.get('birthdate') services.ProfileService.create(user, birthdate) login(self.request, user, backend=settings.AUTHENTICATION_BACKENDS[1]) return super(SignUpView, self).form_valid(form) The user is created successfully, and as you can see I want to log in that newly created user automatically. But for some reason (I have tried to troubleshoot googling around) the user is not logged in after the successful sign up. Here you can see the custom form in use that inherits from UserCreationForm: class RegistrationForm(UserCreationForm): email = forms.EmailField(required=True, label='EMAIL') birthdate = forms.DateField(required=True, label='FECHA DE NACIMIENTO') friend_token = forms.CharField( required=False, label='CÓDIGO AMIGO', max_length=8) class Meta: model = User fields = ( 'username', 'email', 'birthdate', 'password1', 'password2', 'friend_token' ) def clean(self): email = self.cleaned_data.get('email') if User.objects.filter(email=email).exists(): raise ValidationError("El email ya existe") return self.cleaned_data And here (if it is of some use) my settings.py … -

Django can not set AppConfig atrribute during ready()
i'm currently trying to set a custom attribute for the AppConfig of one of my project's apps. The point of doing so is, that the code producing the value needs to be run after App initialization. That's when i came accross the ready() method of AppConfig. So suppose i got an app called content my apporach is : from importlib import import_module from django.apps import AppConfig from django.conf import settings class ContentConfig(AppConfig): name = "content" sone_val = None def ready(self): value = ... # some code if value: self.some_val = value The ready() method gets called and at that point the value is correct. However when i try to access this attribute later in views.py via from django.apps import apps as django_apps django_apps.get_app_config("content").some_val the result is None instead. What am I overseeing/missunderstanding here? -
TemplateDoesNotExist Exception - Django is not loading template from namespaced template

API with Signed endpoint security in Django REST framework
I'm looking up on how to develop an API with an API key (for the project) and Auth Token (for the users). I'm interested in this kind of authentification for the API key Binance API but I can't find any information on how to do it. Looking at other exchanges APIs looks like is a standard way to do it. Is there any documentation or tutorial on how to accomplish this kind of API key security? So far I found this https://pypi.org/project/djangorestframework-api-key/ but I think it is not what I'm looking for. -

I am using Django I am trying to make image slider using bootstrap, this is my code so far {% extends "blog/modelsbase.html"%} {% block content%} <body> <div id="carouselExampleControls" class="carousel slide" data-ride="carousel"> <div class="carousel-inner"> <div class="carousel-item active"> <img class="d-block w-100" src= "/media/models/dd08-43fc-ae2b-c6bc75ade6f6.jpg" alt="First slide"> </div> {% for image in images %} <div class="carousel-item"> <img class="d-block w-100" src= "{{image}}" alt="Second slide"> </div> {% endfor %} </div> <a class="carousel-control-prev" href="#carouselExampleControls" role="button" data-slide="prev"> <span class="carousel-control-prev-icon" aria-hidden="true"></span> <span class="sr-only">Previous</span> </a> <a class="carousel-control-next" href="#carouselExampleControls" role="button" data-slide="next"> <span class="carousel-control-next-icon" aria-hidden="true"></span> <span class="sr-only">Next</span> </a> </div> </body> {% endblock content%} </html> this is my views.py from django.shortcuts import render import os images = os.listdir('/media/models/model1') def test_model_bt(request): return render(request,'blog/model1.html',{'title':'TEST_MODEL','images':images}) The images are showing correctly,I would like to place the images inside some sort of container to give them max size [800x800] (if they are larger than it reduce size else pass), how can I do it ? Note:for now my code is "mobile friendly" I would like to keep that I got my slider from Carousel · Bootstrap
