Strange behavior when sending file to django server in vuejs
When sending my audio files in vuejs I kept getting errors 'the submitted data was not a file, check the encoding type on the form.' So I tried giving it a file directly: let file = new File(['hello', ' ', 'world'], 'hello_world.txt', {type: 'text/plain'}); console.log(file) var audiopost = { id: "11", user: "username", room: "roomOne", "audiofile": file} this.$store.dispatch("audio/createAudio",audiopost); However, when analyzing in Burp the resulting post request, the audiofile field was empty.. Do you have any Idea what is happening ? Thanks for reading ! Empty Audiofield burp request -
How to "skip" submodule declaration on import
Starting with the structure (this is a Django project). root/ app_1/ views.py my_module/ __init__.py submodule/ __init__.py mixins.py I can normally import on app_1/views.py with the full declaration. from my_module.submodule.mixins import MyMixin But I wish to skip declaring submodule. from my_module.mixins import MyMixin I've tried some combinations of from x import y on both __init__.py files in my_module and sub_module but I've only managed to skip the submodules altogether. from my_module import MyMixin I don't love this option because it hides all my files. Is there a way to get it the way I want? -
How to retrieve a stripe subscription id after a checkout session in a django project?
Here is my problem. I made a stripe subscription for my django project, and I used the checkout session method. I would like to retrieve the stripe subscription id, after the payment, to put it on my customer model, so I can make a cancel subscription method for the customer, because the method given by stripe require to have this id : stripe.Subscription.modify( *sub_id*, cancel_at_period_end=True ) or stripe.Subscription.delete(*sub_id*) The problem is that I can't find the id anywhere else than in my stripe account, where I have every informations I can need, but I can't find how to retrieve it through code after the payment has been done. I need to fill the field 'stripe_sub_id' in my customer model so i can make the cancel method work. Here is the method that creates the checkout session @csrf_exempt def create_checkout_session(request): if request.method == 'GET': domain_url = 'http://127.0.0.1:8000/' stripe.api_key = settings.STRIPE_SECRET_KEY try: checkout_session = stripe.checkout.Session.create( success_url=domain_url + 'projets/success?session_id={CHECKOUT_SESSION_ID}', cancel_url=domain_url + 'projets/cancelled/', payment_method_types=['card'], mode='subscription', line_items=[ { 'price': sub_price_id, 'quantity': 1, } ] ) return JsonResponse({'sessionId': checkout_session['id']}) except Exception as e: return JsonResponse({'error': str(e)}) And here is my script to activate the session //Get stripe publishable key fetch("/projets/config/") .then((result) => { return result.json(); }) … -
How to populate dropdown menu from Django database
I would like to create two dropdown menus from the data out of a database. I have been struggling with this for the past few hours and have no idea how to fix it. I have imported my CSV file to my database using Jupyter with sqlite3: import pandas as pd import sqlite3 lol = pd.read_csv('LeagueofLegends.csv') del lol['Address'] path = '#path to directory' cxn = sqlite3.connect(path + 'db.sqlite3') cxn.cursor().executescript('drop table if exists lol;') lol.to_sql('lol', cxn, index = False) cxn.close() As far as I know, everything went well, but now I'm at the point where I want to make a few dropdown menus from the data from the database. Down below I have included a snippet of the data. The two dropdowns I want to create are a blueTeamTag and a redTeamTag dropdown. I have tried this for hours but have no clue how to do this. Also, both the blueTeamTag and the redTeamTag contain duplicated, that I have to get rid of before putting it in a dropdown. I also included my views.py, models.py, and the HTML script where the dropdown menus should go. views.py: from django.shortcuts import render from django.http import HttpResponse, HttpResponseRedirect from .models import Lol # Create … -

How to assign a user to a new object with Django?

How to trace code in a Django production system
My code behaves different in the production code, than on my development machine. I would like to debug/trace it. Since it runs on Heroku. I use PyCharm. AFAIK I can't insert import pydevd_pycharm; pydevd_pycharm.settrace(... into the code. I don't need a fancy GUI a command-line tool would be fine, too. I would be happy if I could see all lines which get executed during a particular http request. How to solve this for production systems? -
Converting .csv string data into DateField type in Django models.py

What shall I use for full text search and fuzzy search on a social network django site with a postgresql database?
So, I was looking for a search engine for my new django project with a postgresql database and I ended up with elasticsearch and sphinx. I've chosen the second one, because I thought that if you're searching in a lot of posts you need a fast search, which uses less memory, but after looking at realization of sphinx I went up like, "How do I do that on python and can I do fuzzy search with it?". I've found few django-sphinx libraries, but they seem to be abandoned (last update was 5 years ago), and in sphinx documentation I didn't find anything about django, just few mentions of python. So, is sphinx still alive and how can I use it with django, or should I choose another engine for my tasks? -

Passing arguments to Django CBV for queryset
I'm trying to figure out how can I pass arguments from a generic view where a user submits a form to a cbv template view. My first generic view is as such: def homepage(request): if request.method == 'POST': form = SearchForm(request.POST) if form.is_valid(): form_data = form.cleaned_data return redirect('filtered', city=form_data['city'], category=form_data['category']) else: form = SearchForm() return render(request, 'index.html', context={'form': form}) What Im trying to achieve is that when a user choses a city and a category then he gets submitted to a homepage that is a TemplateView where there's a queryset based on objects that are in the selected city and of selected category. class ListAd(ListView): model = Ad template_name = 'filtered' queryset = # here Im expecting to make a query based on the 'city' and 'category' chosen in previous view How to pass the city and category arguments to the ListAd view so I can use them in the queryset? This is the ursl.py urlpatterns = [ path('list_new/<city>/<category>/', views.ListAd.as_view(), name='filtered'), ] Any help would be appreciated. Thank you
