Best practices for storing encrypted data that needs to be decrypted
I have a use case where I need to store userIDs and passwords to access other systems in my DRF App with a PostgreSQL DB. I must be able to retrieve this information, but I don't want to store it in plain text in the data base. The credentials will be used to login to other systems to collect data. Hashing is not an option as I need to be able to decrypt the encrypted passwords as they will be used to log into other systems. I was thinking using a vault (hashicorp), but then I need to store the keys to access the vault. That seems just shifting the problem, but not a solution. I am looking for a encryption/decryption that has not more than 2 secrets (key and vector) that could be the same for all credentials and provides a single string per password that can be stored in the DB. No fancy PostgreSQL features that are not supported by Django/DRF. I am not looking for long explanations about that you should not store a userID/Password information in a DB! -

JAVASCRIPT: After sending Item to Database (POST) the window.location.reload() does not work. How to refresh the Data in HTML-Template?
I recode a Tutorial on Youtube. Django, Python, HTML an Javascript. Everthing works fine exept the window.location.reload() function. I try some workarounds with windows.reload(true), window.href = window.href location = self.location and some more. I have a hunch that the reload is executed before or during the code before the reload. But I do not know. The goal is to send the data from the input to the database and only then refresh the page. This ist the Code from the tutorial: index.html (shortened) <body> <header> <h1>Shoppinglist</h1> <div id="input-field"> <label for="item-input">Was möchtest du einkaufen?</label> <input type="text" name="item" id="item-input"> </div> <button id="btn" onclick="addItem()">+</button> </header> <div id="item-table"> {% for row in all_items %} <div class="list-item"> <input type="checkbox"> {{row.name}} </div> {% endfor %} </div> <script> function addItem(){ let itemName = document.getElementById("item-input").value; let formData = new FormData(); let token = '{{csrf_token}}'; formData.append('itemName', itemName); formData.append('csrfmiddlewaretoken', token); fetch('/mylist/', { method: 'POST', body: formData }); window.location.reload(); }; </script> </body> </html> views.py from django.shortcuts import render from .models import ShoppingItem # Create your views here. def mylist(request): if request.method == 'POST': print('Received date: ', request.POST['itemName']) ShoppingItem.objects.create(name = request.POST['itemName']) all_items = ShoppingItem.objects.filter(done = 0) return render(request, 'index.html', {'all_items':all_items}) models.py from django.db import models from datetime import date #Create your models … -

Django Rest Framework get filtered queryset in custom get function
So I have an APIView like this: from rest_framework.views import APIView class MyAPIView(APIView): queryset = MyObject.objects.all() filter_backends = [MyCustomFilterBackend, DjangoFilterBackend] filterset_fields = ["field1", "field2"] def get(self, request): s = StatManager(self.queryset) return Response(s.dashboard()) where I filter bunch of stuff using MyCustomFilterBackend and DjangoFilterBackend. My goal is to give the filtered queryset to StatManager so it generates stats for the dashboard. Currently, s = StatManager(self.queryset) does not take filters into account. How can I provide the filtered queryset in my get function? I read the DRF documentation. I was expecting for APIView to have some function like get_filtered_queryset(). I read Filters of Django REST Framework inside GET function? and DJango filter_queryset but they have no adequate answers. -
how to disable django page caching
is there a way to prevent page caching in django? Because I have 2 views. view2 is only accessible if a request.session['iv'] exists. This is only created within view1 of a post request and is also deleted at the beginning of view1, so that access to view2 is not possible for the time being. If I am then redirected from view1 to view2 I can easily go back with the browser and land on view1. The problem is I can then go back to "show next page" and end up on view2 although the request.sesion no longer exists. This must be because the browser opens a cached version of view2, which I want to prevent. -

Fullfill drf serializer attribute from dict by key name

DRF serializer method field - seems to be hard to apply when there is few fields of different formats - charfields, datefeilds, intfields and all I need is just to pull values from dict Custom renderers - but they are applied after serialization and validation will fail and will affect whole view Any other suggestions? -
