Django: Renew and set JWTs as HttpOnly cookie using a middleware. Response() returning django.template.response.ContentNotRenderedError
I have a custom middleware where I am adding SimpleJWR HTTP_AUTHORIZATION to every authorized requests as I am using HttpOnly cookies. Also here I have added code to check whether an access token is valid or not. If not, then a request is sent using requests which fetches the new access token and set's it as HttpOnly cookie. So far, I'm able to get the new access token after it expires. But, the url from where I dispatched the request returns this error: raise ContentNotRenderedError( django.template.response.ContentNotRenderedError: The response content must be rendered before it can be accessed. At the first request it works. It returns the response and saves the tokens as HttpOnly cookies but after the token expires and if I again make the request, instead of (what I want to happen) saving the tokens as HttpOnly cookies and returning the same response again, it is returning the error. I think the issue is in the response statements. My middleware: import jwt import datetime import requests import json from rest_framework.response import Response from django.conf import settings class AuthorizationHeaderMiddleware: def __init__(self, get_response=None): self.get_response = get_response def __call__(self, request): access_token = request.COOKIES.get('access') refesh_token = request.COOKIES.get('refresh') print(refesh_token) # check if the access … -

Any suggestions for a Django Rest Framework JWT package that sets and supports HttpOnly cookies?
I've been using djangorestframework-simplejwt for a while but now I want to store the JWT token in the cookies (instead of localstorage or front-end states) so that every request that the client makes, contains the token. So did some research on it and the most relevant result I found was this stackoverflow question, in which the author is using djangorestframework-jwt which has a pre-configured setting for cookies called JWT_AUTH_COOKIE. So figured switching to that package but then ended up finding out that the package is pretty much dead. Although there is a fork for the djangorestframework-jwt that is recommended to use instead, I was wondering if anyone has any better suggestions of packages or anyways for setting the JWT token in an HttpOnly cookie in the response even in djangorestframework-simplejwt package or something. -

Celery container crashes when using django cache_page (InvalidCacheBackendError)
I am facing an issue with my Django webapp project. I am running a containerized environment using Django, Postgres, Redis and Celery. Mainly, I want to use Redis for caching and Celery to set up live updates. So far, I have been able to connect to redis and celery and store celery task results in the redis cache.

Django creating dependent dropdown menus using pyodbc queries
I'm trying to create a dependent dropdown menu in django. Basically, I have 3 menus, which are Division, District and Store. What I need is that depending on the value selected on Division, Disitrict will be filtered, and depending on the district, store will be filtered. I've seen some methods of doing here in stackoverflow but all of them are using models, and I'm using pyodbc. I haven't been able to implement any sort of filtering succesfully since I'm new to html/javascript/ajax, but here is how my files look like. views.py def homeView(request): conn = privatestuff cursor = conn.cursor() cursor.execute('''SELECT DISTINCT division FROM DimStore WHERE NOT division IN ('NULL', 'Closed') ''' ) divisions = [x[0] for x in cursor.fetchall()] cursor.execute('''SELECT DISTINCT district FROM DimStore WHERE NOT district IN ('NULL', 'Closed') ''' ) districts = [x[0] for x in cursor.fetchall()] cursor.execute('''SELECT DISTINCT SAP4Digits FROM DimStore ''' ) sap = [x[0] for x in cursor.fetchall()] context = { 'divisions' : divisions, 'districts' : districts, 'sap' : sap } return render(request, 'dashboard/home.html', context) home.html <form> <div class="row"> <div class="form-group"> <label for="example-date">Start Date</label> <input class="form-control" id="example-date" type="date" name="date"> </div> <div class="form-group"> <label for="example-date">End Date</label> <input class="form-control" id="example-date" type="date" name="date"> </div> <div class="form-group mb-3"> <legend>Division</legend> … -

Django define update_fields when creating objects in model
I am using a SQL Server table with period columns, and my model in Django is defined as class Client(models.Model): id = models.AutoField(primary_key=True) name = models.CharField(unique=True, max_length=40) sys_start_time = models.DateTimeField(db_column="SysStartTime") sys_end_time = models.DateTimeField(db_column="SysEndTime") class Meta: managed = False db_table = "client" where sys_start_time and sys_end_time are period columns. Due to sql server rules, any query defining values for these columns are invalid, which means that the sql query django generated when creating or updating this model won't work. I managed to exclude them in update_fields when performing update so that django will generate queries without period columns, but I can't use the same update_fields parameter when creating an object, otherwise I get an error saying Cannot force both insert and updating in model saving. Is there a way to let django ignore certain fields when creating an object? OR Is there a way to tell Django to send DEFAULT (sql server keyword, not string) as the value for these period columns? -

How do you implement CSRF tokens in django rest framework?
I have noticed that when using django and you make a post request, using a form for example, django asks you to add the csrf token, but when I was fetching data from an api created with django rest framework with react I realized that when I didn't send the csrf token there wasn't any error with the application. In this app I am using token authentication with knox and I have seen some posts about how to use csrf token with session authentication. My question is if token authentication does not need the csrf tokens or are they passed automaticaly by react? Thanks in advance. -
JavaScript cloning an element with a loop inside
I'm new to coding/web development, I'm using JavaScript function to clone an Element which has a loop inside it. But the function is not working. Following is my HTML code: <table> <tr> <td id="add"> <Select class="selectpicker form-control" name="audience"> <option value="all">All</option> <option value="teachers">Teachers</option> <option value="parents">Parents</option> <option value="students">Students</option> {% for i in range(1,14) %} <option>{{i}}</option> {% endfor %} </Select> </td> <td><button type=button onclick="newfield()" class="btn btn-outline-success"> + </button> <button type=button onclick="remove()" class="btn btn-outline-danger"> - </button> </td> </tr> </table> And following is my JavaScript function: function newfield(){ var newselection =document.getElementById("add").firstChild; var newfield = newselection.cloneNode(true); var x = document.getElementById("add") x.insertBefore(newfield, x.firstChild); } function remove(){ var x = document.getElementById("add"); x.removeChild(x.lastChild); } but when I manually insert the numbers from 1 to 13 in attribute. the function works perfectly. As I'm new to coding space I'd like to know whether there's a way to overcome this problem. Thank you. -
Python requests in CRON job getting called twice
I'm not really sure why but each request I make with the Python requests library is getting called twice. I am sure that the CRON job is not called twice as I'm logging a message to a logfile every time it runs. What might be the possible issue for this? Here is a screenshot of the calls: If you take a look at their times, they're very close to each other.
