Django Rest Framework Custom Throatting Not Working
I'm creating a custom throatting for an api I've developed using django rest framework, currently there are two subscription plans, each one with its own quota, so here, in throatting.py, I've created a custom class that fetches the user quota and overwrites it to the default setting: from rest_framework.throttling import UserRateThrottle def get_user_daily_limit(user): # Some calculations # return the daily quota for user, f.ex: 20 request class SubscriptionDailyRateThrottle(UserRateThrottle): scope = "subscription" def __init__(self): super().__init__() def allow_request(self, request, view): if request.user.is_staff: return True if request.user.is_authenticated: user_daily_limit = get_user_daily_limit(request.user) if user_daily_limit: self.duration = 86400 self.num_requests = user_daily_limit else: return True if self.rate is None: return True self.key = self.get_cache_key(request, view) if self.key is None: return True self.history = self.cache.get(self.key, []) self.now = self.timer() while self.history and self.history[-1] <= self.now - self.duration: self.history.pop() if len(self.history) >= self.num_requests: return self.throttle_failure() return self.throttle_success() And this is my settings.py: REST_FRAMEWORK = { 'DEFAULT_AUTHENTICATION_CLASSES': [ 'rest_framework.authentication.TokenAuthentication', ], 'DEFAULT_THROTTLE_CLASSES': [ 'rest_framework.throttling.UserRateThrottle', 'app.throttling.SubscriptionDailyRateThrottle' ], 'DEFAULT_THROTTLE_RATES': { 'user': '5/second', 'subscription': '16/day' } } I checked the tutorial I was following and everithing seems to be fine but when I test it doing request I can't see neither the 5 seconds betweet requests nor the maximum of 16 request per day, … -
Run Django Custom Command locally?
Owing to not having a Credit Card, can't use heroku's task scheduler. https://devcenter.heroku.com/articles/scheduling-custom-django-management-commands This site talks about running the custom command locally via cli. Is it possible to automate this cli "script" so it runs every day? I know it's possible in normal python scripts but unsure about this one. All leads appreciated thanks a lot. -
Docker not recognising Dockerfile
I am running into a problem where docker isn't recognising my Dockerfile. -What I am trying to do: Make a docker upload of an existing heroku app. -The error that occurs:**** failed to solve with frontend dockerfile.v0: failed to read dockerfile: open /var/lib/docker/tmp/buildkit-mount649479195/Dockerfile: no such file or directory -What I have tried: Ensuring docker file is where my manage.py file is and ensuring it has the title Dockerfile. -My set up: I have a django project in a folder on on my desktop. The folder is called site1. In the folder is all the django files. Including my manage.py and Dockerfile I have created. My heroku app is called: tactilefire. My django app is called site1app. My docker file consists of: FROM python:3.8 ADD . /site1/ WORKDIR /site1 RUN apt-get update RUN apt-get install -y pandoc RUN apt-get install -y texlive-fonts-recommended RUN pip install --upgrade pip RUN pip install -r requirements.txt RUN python manage.py makemigrations && python manage.py migrate CMD gunicorn --bind 0.0.0.0:$PORT site1.wsgi so when I try build my docker i get the error. Any ideas? there must be something wrong with my set up? -
Can I make a Django mixin that adds context variables just before template render?
I have a Django application that uses a JSON API as its data source. Here's a simplified example of use in one of my views.py: class GroupsList(LoginRequiredMixin): def get(self, request, **kwargs): # Get file list and totals try: group_list = group_adapter.list() # makes an API call and ALSO populates a meta info class except APIAccessForbidden: return HttpResponseRedirect(reverse('logout')) return render(request, 'groups/index.html', { # can I make a mixin to add data here gained from the API call? 'group_list': group_list, }) This line: The group_adapter.list() call populates some meta information into another class, that's not related to the group_list itself. I'd like to pass that data to the template. Ordinarily I'd use a context_processor, but when the context processor is called, the API call hasn't been made yet. I could manually check the information and add it to the render() method, but then I'd need to do that in dozens of different views. Can I use a mixin here that adds this information to context AFTER the view code runs but BEFORE render passes information to the template? In other words is there a way to do this: class GroupsList(LoginRequiredMixin, RenderMetaInfoMixin): and then create a mixin something like this? class RenderMetaInfoMixin: def … -

can you combine functions in views.py using django?
I have two functions in my views.py def example1(request) return render(request, 'example1.html') def example2(request) return render(request, 'example2.html') I am curious if there is a feature django supports that allows me to better group these functions without being redundant? -

How do I initialize my admin Class from a "custom django-admin command"?
I have functions in my admin Class that I'd like to perform on a regular basis (every 10 minutes). I am trying to use the "custom django-admin commands" solution ( https://docs.djangoproject.com/en/3.1/howto/custom-management-commands/#howto-custom-management-commands ) and will use a cron job to run it. I do have the custom command working with test code, however I am running into a few issues: I'm not sure how to initialize the class (I get errors such as "missing 1 required positional argument"). If I skip instantiation I can call the functions explicitly, but then I run into these next two problems. I'm used to calling internal Admin class functions using "self.functionname()". But 'self' doesn't work when called from my custom management command. Many of my admin functions use the standard 'request' argument; however I don't have a 'request' from my custom management command. These code snippets are paraphrased from the originals. polls/management/commands/performTasks.py from django.core.management.base import BaseCommand, CommandError from polls.models import Question from polls.admin import QuestionAdmin class Command(BaseCommand): help = 'Starts the process.' def handle(self, *args, **options): QuestionAdmin.tasks(self, 'YES') # The following 2 lines I simply use to prove a successful query: myqueryset = Question.objects.filter(author="Tolkien") print(myqueryset) admin.py from django.contrib import admin from .models import Question from … -

How can I start localizing a Web App that wasn't designed with localization in mind (how can I find localizable strings)?
I am working on a large web application. It has components in both Django and in Angular.js. Our team was recently asked to evaluate the effort it would require to localize the app in French Canadian. Unfortunately, this app is several years old, and it was not designed with localization in mind (e.g., hard-coded strings everywhere). I've done some research, and I've found several best-practices for designing new, localizable apps, but little on transitioning an existing app. Our primary task is to collect a list of all of the localizable strings. Is there any way to automate this process? I thought something like a regex to find all hardcoded strings in html files would be a good start, although it sounds like that may be the wrong path. Any help would be greatly appreciated! -

How to remove specific fields from the django User Model?
From the Django User Model, I'd like to remove some fields such as 'first_name', 'last_name', 'email', 'date_joined'. I want no changes in the Auth system of the User Model, i.e. I still want authentication to be done using the username. I just want to remove some unrequired fields. Will I need to extend the AbstractBaseUser model for this, or can this be achieved just by extending the AbstractUser model? Or is there any other way also to do this ? Thanks in advance ! -

What is the best way to handle multiple clients payment setups? [closed]
Which method is the most clever and professional when first setting up and then handling multiple clients payment services in web-applications?

Stripe has a service for platforms and marketplaces but that doesn't seem to be what I'm looking for. I want to use Django as back-end. How should I proceed? Thanks! -

How to retrieve files from Django FileSystemStorage uploaded in a multisteps form using formtools wizard
I am using Django 3.0 and python 3.8.2 to develop an ads website. To add a post, I used Django formtools wizard. It worked and everything goes nicely. I could save the multiform data. However, I could not retrieve the files from the FileSystemStorage so I can save them. Hence, any help to achieve this or suggestion is much appreciated. I want to retrieve uploaded files, save them to the data base and then delete them from the wizard (from the FileSystemStorage).
