Django CSRF cookie + ReactJS axios post request
HI I've been stuck on this axios post request for couple days. I'm trying to send a post request to the REST API so that it could create a new data entry in the backend. After I sent the post request using axios along with XSRF token and CSRF token, I always got "OPTIONS /endpointURL HTTP/1.1" 200 0" instead of the actual post request Here's my code for the axios post request import axios from '../helpers/axios'; axios({ method: "post", url: "http://endpointurl", withCredentials: true, headers: { 'Content-Type': 'application/json', 'X-CSRF-TOKEN': localStorage.getItem('xsrftoken'), 'csrftoken': localStorage.getItem('csrftoken') // 'XSRF-TOKEN': localStorage.getItem('userToken') }, data: { name: this.state.name, } }).then(res => { console.log(res); console.log(res.data); }) I also tried to send a wrong token along with the post request, I would still get "OPTIONS ..." if i remove withCredentials: true from the code, i would get Forbidden (CSRF cookie not set.) ../helpers/axios import axios from 'axios' /** * Config global for axios/django */ axios.defaults.xsrfHeaderName = "X-CSRFToken" axios.defaults.xsrfCookieName = 'csrftoken' export default axios And this is how I got the tokens // using jQuery function getCookie(name) { var cookieValue = null; if (document.cookie && document.cookie !== '') { var cookies = document.cookie.split(';'); for (var i = 0; i < cookies.length; i++) … -
Django NoReverseMatch error for Tutorial Part 3
Hi I've been trying to figure out why I keep getting the NoReverseMatch error in my program but can't seem to figure out why. I doubled checked that my question.id was correct and checked the urls.py to also make sure that there was nothing wrong but I keep getting the error when I add the {% url %}. I have also been through almost all of the other stackoverflow posts and have still not been able to figure out the issue. Any help is much appreciated!

Delete header in django rest framework response
I'm trying to delete Server header from django rest framework response, but I didn't find an easy way, so I create a middleware to delete it. This is my first try: middleware.py class RemoveHeaders(object): def process_response(self, request, response): response['Server'] = '' return response This middleware works ok, but the problem is that it fills server header with empty string and not delete it. so I tried the next: class RemoveHeaders(object): def process_response(self, request, response): del response['Server'] return response But It doesn't work. server header continues. How can I delete server header?, or do you know another alternative? thanks -
Storing additional information in django using absrtactuser
I have created custom Userclass in django(AbstarctUser). Everything works fine but my password is getting stored as plain text in database even after registering in admin.py. I do not have any forms.py explicitly defined. Also I am using nested serializers following "https://medium.freecodecamp.org/nested-relationships-in-serializers-for-onetoone-fields-in-django-rest-framework-bdb4720d81e6" tutorials My code is as below from django.contrib import admin from .models import BasicUserInfo from django.contrib.auth.admin import UserAdmin class BasicUserAdmin(UserAdmin): pass admin.site.register(BasicUserInfo, BasicUserAdmin) -
CurrentSiteManager via related model
Is it possible to use the CurrentSiteManager to check the site of a related object - not the site of the object itself? So, given the following models:- class A(models.Model): site = models.ForeignKey(Site) class B(models.Model): a = models.ForeignKey(A) I want to use the following manager on B:- on_site = CurrentSiteManager('a__site') Otherwise, I'll have to add site as a ForeignKey to both A and B and manage all the issues that come with that. But it looks like the CurrentSiteManager wants the 'site' field to be on the B class, not on A. Is my only solution to write my own CurrentSiteManager? -

Run Celery in production with Supervisor
I am trying to launch Celery v3.1.25 in production. As I have found in docs there are 4 ways to run it, 1 of them is to use Supervisor. I have used it before - my Django project is running using it.

How to use Django __time lookup in a queryset
I have a model with 2 datetime fields which looks like this: class Booking(models.Model): start_date = models.DateTimeField() end_date = models.DateTimeField() ... As test data I have 2 bookings with start_date before 17:30 and 2 bookings after 17:45, all on the same day (8 May 2018). I am trying to filter the bookings with the __time lookup to find all the bookings before (and including) 17:30. My queryset is: bookings = Booking.objects.filter(date__time__lte=datetime.time()) Where datetime.time prints as datetime.time(17, 30) and where the date part of the datetime is the same as the bookings dates. The above query is returning an empty queryset but if I use the same query except filtering for times greater than datetime.time() i.e. bookings = Booking.objects.filter(date__time__gte=datetime.time()) The queryset returns all the bookings (where it should only return the 2 bookings with start_date after 17:30). Can someone please explain to me how the __time lookup is meant to be used? EDIT I updated the filter to bookings = Booking.objects.filter(start_date__time__lte=datetime.time()) and the result is the same. -

Django - Create unique ManyToManyField?
I have been working with Django for a little while now, and I've been reaching barriers in regards to storing data with the framework. I'd like to have a ManyToManyField in which its objects are user-specific. Example: User1 Grades A+ B+ User2 Grades: B B- With my current setup, both users will have: A+,B+,B,B-. I am not sure how to work around this without queries. Course_Grades = models.ManyToManyField(CourseGrade, default=1) Assignment_Grades = models.ManyToManyField(AssignmentGrade, default=1) -
Django Test Wants Access To Master Database MS SQL Server
I've got an application that is running Django 2 that connects to a Microsoft SQL Server backend. We're in a big environment where things are pretty tightly controlled - a user account has access to the database that houses all the tables for my django application. It does not have access to the master database on the SQL Server and any request for an account that does have that level of access would likely be denied. It can create tables in the existing database, but cannot create entirely new databases. When I run the tests for the application I get the error: Got an error creating the test database: ('42000', "[42000] [Microsoft][ODBC Driver 13 for SQL Server][SQL Server]CREATE DATABASE permission denied in database 'master'. (262) (SQLExecDirectW)") So what is the best course of action for this? Is there a way to manually create the 'test database' and have Django use that for testing purposes so it isn't trying to create a new database when running tests? -
Proper way of streaming JSON with Django
i have a webservice which gets user requests and produces (multiple) solution(s) to this request. I want to return a solution as soon as possible, and send the remaining solutions when they are ready. In order to do this, I thought about using Django's Http stream response. Unfortunately, I am not sure if this is the most adequate way of doing so, because of the problem I will describe below. I have a Django view, which receives a query and answers with a stream response. This stream returns the data returned by a generator, which is always a python dictionary. The problem is that upon the second return action of the stream, the Json content breaks. If the python dictionary, which serves as a response, is something like {key: val}, after the second yield the returned response is {key: val} {key: val}, which is not valid Json. Any suggestions on how to return multiple Json objects at different moments in time? -
Search engine in javascript and django
Good day, I'm pretty new in django and python and newer still in javascript. And I'm mixing everyone! :( Step to tell you that I'm making a website where a Manager enters the movements performed during a work day, separated into a list that also that list is divided into sublists. On the website you are asked to enter the number of movements made in that workday (sublist), each of these movements correspond to different people who are discriminated against by an AUTOS AND JUDGE EJ: AUTOS: 251254 Court: PAZ 6. In javascript I managed to enter the number of movements you want to load and automatically generate the amount of input and select that I need. At that moment that the manager decided the number of movements that will be entered in that sublist, you must identify the client to whom the operation hosted in my database will be loaded, modeled in django. Then in all the input you must enter the AUTOS number and in a SELECT - OPTION select the COURT to which that car belongs and bring me the name of the client lodged in the data base and the doubt that I have is how … -

Django - Showing items that are assigned to current user's email
