How to send lockout response of django-axes in the login api response
The django (django-rest-framework) app is using Simple JWT for the authentication and now I am trying to integrate the django-axes in the framework. I am able to lockout the user in 5 failed login attempt and its working as expected. Everything is working fine but When the user got locked out I am not able to send the response to the user notifying him that he is locked out. Problem Statement : When user login, he recieves No active account found with the given credentials in failed attempt. But once he reaches the lockout limit he receives Account locked for 1 hours: too many login attempts. Simple-JWT Configuration: class MyTokenObtainPairSerializer(TokenObtainPairSerializer): def validate(self, attrs): print("Yes.........") data = super().validate(attrs) data['username'] = self.user.username data['id'] = self.user.id data['first_name'] = self.user.first_name data['last_name'] = self.user.last_name data['phone'] = self.user.phone data['email'] = self.user.email test = update_last_login(None, self.user) return data MyTokenObtainPairView class MyTokenObtainPairView(TokenObtainPairView): serializer_class = MyTokenObtainPairSerializer def send_response(self): return Response(self.serializer_class.data, status=status.HTTP_200_OK) I guess we need to override this validate function. But failed to do so. I was also trying to use: from axes.signals import user_locked_out class TokenObtainSerializer(serializers.Serializer): username_field = User.USERNAME_FIELD default_error_messages = { 'no_active_account': _('No active account found with the given credentials') } def __init__(self, *args, **kwargs): super().__init__(*args, **kwargs) … -

Django template: resolve nested variable [duplicate]
In the context I pass to the template, there are variables var_1, var_2, var_3, etc. I want to show the value of all those variables using a for loop. To do that, I write this code: {% with "1 2 3" as lst %} {% for x in lst.split %} <p>{{"var_{{ forloop.counter }}" }}</p> {% endfor %} {% endwith %} With this, I hope for each iteration, it first resolves the value of forloop.counter (e.g. 1), then resolves the value of the variable var_{{ forloop.counter }} (e.g. var_1) and shows this value. However, I got the error below: django.template.exceptions.TemplateSyntaxError: Could not parse the remainder: '"var_{{ forloop.counter' from '"var_{{ forloop.counter' Is there any way I can get my desired result? -

Webhook get blocked somehow and not trigger Django view function
I have a website set up using Django and digital ocean. I am trying to add a 3rd party webhook to my site url to trigger some code, however, the view function connected to my site url never gets called (I put debug code at first, and it never got called). I try to relink the webhook to the webhook.site, and it works. I have checked the webhook endpoint URL, no problem at all. If I type the webhook endpoint URL on the browser, my debug code will get triggered. It seems like, for some reason, when the webhook tries to call my code, this request gets blocked somehow and never reaches my code. I tried to put a @csrf_exempt to my view function, but it still does not seem to be called. Any idea? -
Cant get Information out of request data (Django/Postman)
Im trying to build an api with Django. I think i build it correctly but from, for example Post-request data, i get as the field values "none" Maybe you can help me to solve this problem :) Heres the api: def apiRequests(request): if request.method == "POST": print(request.POST.get("name")) print(request.POST.get("publisher")) print(request.POST.get("price")) #Game.objects.create(name= request.POST.get('name'),publisher = request.POST.get("publisher"),price = request.POST.get("price")) elif request.method == "GET": response = Game.objects.filter(name = request.GET.get("name")) return render(request,"apirequests.html") As you may see i'm printing out the data i receive. This looks like this: [26/Aug/2022 07:11:41] "GET /api/ HTTP/1.1" 200 263 None None None Here's the model class: class Game(models.Model): name = models.CharField(max_length=200) publisher = models.CharField(max_length=200) price = models.BigIntegerField() def __str__(self): return str(self.id) + " " + self.name And here is the data I'm sending as a Post-request from Postman to the api: { "name": "FarCry", "publisher": "EA", "price": "35.66" } I think i should say that i got Problems with the CsrfViewMiddleware-Token so i commented it out in the settings.py, maybe there is the problem. Thanks for helping -
Django Models - Django admin is throwing a DataError for "setting" a string to an integer within a Foreign Key
I've setup some models for Stripe payments, one for Product and the other for Price. You can see I've set the API value from Stripe as the Primary Key. These are their fields: class Product(models.Model): stripe_product_id = models.CharField(max_length=100, primary_key=True) name = models.CharField(max_length=100) def __str__(self): return self.name class Price(models.Model): stripe_price_id = models.CharField(max_length=100, primary_key=True) product = models.ForeignKey( Product, on_delete=models.CASCADE, to_field="stripe_product_id") price = models.IntegerField(default=0) Django admin let me create Product fine using the string api key, then when I went to create a Price object using the Price API value from Stripe, and having the foreign key set to my Product. I was given the following error (my api values are redacted): DataError: invalid input syntax for integer: "prod_xyz" LINE 1: UPDATE "payments_price" SET "product_id" = 'prod_xyz... I tried using the to_field parameter in Foreign Key but that didn't seem to fix it. Does anyone know the method to fix it? Or should I just go back to using the default primary key with the product/price id as Unique? Below is what I'm attempting to do in Admin. -
Which frontend(React.js/React Native) and backend(Flask/Django) frameworks should I choose?
I'd like to develop a portfolio manager web app. In this app users will be able to manipulate portfolios by adding/editing/removing transactions and see their portfolios statistics in real time(change of the stock prices, total return). I have a list of requirements and examples of screens for the project below. It's worth to mention that I don't have experience in web-development and only know the basics of python and js. Frontend: Support both Desktop and Mobile web app versions Interactivity (Adding/Editing/Removing portfolios/transactions) Content expansion (More transactions/holdings/portfolios are added) Frequent data updates (Prices of holdings/total returns) Technologies: React.js/View.js/React native Backend: Localization (For now only English) Authorization (Users should be able to sign up/login in the system) Real time data streaming (Get financial data from yahoo or other financial sources) Technologies: Django/Flask Portfolio screen Portfolios screen AddTrade view Settings screen -
Django pass variable from button to view
This is my template file which contains a menu that generates dynamically: {% block idfs %} {% for each in list %} <li> <a href="{{each}}">{{ each }}</a> <button type="submit" value={{each}} onclick="location.href='{{each}}'" name='{{each}}'>Go</button> </li> {% endfor %} {% endblock %} I have the button there, and I need the name for each button in my view. So when user clicks on any button, I can process the output in my view. I have tried this in my view: def example(request): item = request.POST.get('name') print(item) But it doesn't work. It always returns None. Shouldn't it work? Since I am using 'name' to pass the data from template? How can I pass the generated names in my buttons to my view? -
Django new project Run Add Grop page not save selected permissions
Just create a new project, Run Add Grop page, add a new group, and select some permissions. Press the save button. A result is a new group added with no permissions. Why? I modify a little code as below: class GroupAdmin(admin.ModelAdmin): search_fields = ("name",) ordering = ("name",) # filter_horizontal = ("permissions",) def formfield_for_manytomany(self, db_field, request=None, **kwargs): if db_field.name == "permissions": qs = kwargs.get("queryset", db_field.remote_field.model.objects) # Avoid a major performance hit resolving permission names which # triggers a content_type load: kwargs["queryset"] = qs.select_related("content_type") return super().formfield_for_manytomany(db_field, request=request, **kwargs) mark out this line : filter_horizontal = ("permissions",) , for not showing the selected items listbox. run the same page: Press the save button, then got the desired result. Although the answer is right, without filter_horizontal = ("permissions",) Listbox is not suitable for users. I think the add group page is the basic function page, and should not have bugs. Why did no one fund or reply to this problem? -

How to get value of django form within that same form before submission?

How to create a Domain Name for a Django App in a LAN
I recently built a Django app that I am running on a Linux machine with Gunicorn and NGINX. The app is being run inside my company's network which is predominantly a windows environment. Currently, I am able to access the web app via the server's IP address. I know if it was a windows machine I could use the DNS to have it called by a DN. How accomplish this given that it's a Linux machine? For example, I would like to have the company users call the web app from a browser using http://analytics instead of its IP address. Would make the app much more user-friendly instead of always typing in the IP and just for best practice it's probably not secure to be showing the end user the IP anyways.
