CSRF verification failed. Request aborted.No solution works for me on the internet

Importing Model from different App - Getting Relative Import or No module Errors
I've read numerous Stackoverflows on this subject and unfortunately still don't understand what's going on and can't get this to work. I'm trying to import a model contained in a different app of the same project. I've tried just about everything including: from ProjectName.Appname.models import Class from ..AppName.models import Class import ProjectName.Appname.models (then reference via models.ClassName) from Appname.models import Class Nothing seems to work. I either get a no module error, or relative import error. Note, PyCharm doesn't show any errors and displays the location of the file/class when hovering over the import, so naming is correct. The error only occurs when running check. -
SSL/TLS Error when Testing Django API via HTTPS on Localhost
In an effort to test an API via an HTTPS connection locally, I followed the approach described here by Evan Grim where I use stunnel4 as a middleman between my requests and my API server. Here's a minimalist urls.py that will generate a token provided a valid username and password. from django.urls import include, path from django.contrib import admin from rest_framework_simplejwt import views as jwt_views urlpatterns = [ path("admin", admin.site.urls), path('api/token/', jwt_views.TokenObtainPairView.as_view(), name='token_obtain_pair'), path('api/token/refresh/', jwt_views.TokenRefreshView.as_view(), name='token_refresh'),] I have also modified the stunnel4 config file as below. pid= cert = stunnel/stunnel.pem sslVersion = all foreground = yes output = stunnel.log options = NO_SSLv2 [https] accept=8443 connect=8001 TIMEOUTclose=1 However, when I try any route via postman or curl (at port 8443), I receive the following errors.

SearchVectorField - joined reference not allowed for taggit field
My model definition is as follows (a simplified model of the one being used in actual product. There are a coupe of other fields: from django.db import models from taggit.managers import TaggableManager from django.contrib.postgres.search import SearchVectorField from django.contrib.postgres.indexes import GinIndex class Product(models.Model): tags = TaggableManager() search_vector = SearchVectorField(null=True) class Meta: indexes = [ GinIndex(fields=['search_vector']) ] I run make migrations and migrate commands. These work correctly. I then run the following set of commands to build the index: search_vector = SearchVector('tags__name') Product.objects.all().update(search_vector=search_vector) I end up getting the following error: django.core.exceptions.FieldError: Joined field references are not permitted in this query This is clearly caused by the tags__name field, but I am not sure how to solve it. Can someone please explain what I would need to do in order to run the above commands correctly? Thanks! -
How to unpack a Python queued job results?
I finally got to setting up RQ to help me with long running function calls in django, but I'm running into a problem with unpacking the values from a queue's result. I checked out the docs as per https://python-rq.org/docs/results/ but to no avail. Here's what my code currently looks like under views.py: def render_data(request): reddit_url = request.POST.get('reddit_url') sort = request.POST.get('sort') res = q.enqueue(run_data, reddit_url, sort) val1, val2 = res.result data = { 'val1': val1, 'val2': val2, } return JsonResponse(data) The expected response would be the returned values, but instead, in console I receive an error 500 along with createError.js:16 Uncaught (in promise) Error: Request failed with status code 500. In Heroku console, the error is File "/app/pc_algo/views.py", line 49, in render_data 'val1': val1, NameError: name 'users_data' is not defined Am I unpacking the jobs results wrong? I've tried looking up the error but I couldn't find a better tutorial on RQ results than the one above. -

Django cannot find new modules, using pyenv and virtualenv
I’m sure this is pretty straightforward to someone experienced. I’m learning Django through the Wedge of Django ebook. I’m using Python 3.8.7 installed via pyenv like so: pyenv install 3.8.7 Then I’ve set up a virtualenv like so: pyenv virtualenv 3.8.7 everycheese I activate the virtualenv in my repo like so: pyenv local everycheese The environment is shown as active in the prompt, as it starts with (everycheese). The main project is cloned from Django Cookiecutter https://github.com/cookiecutter/cookiecutter-django I’ve then used pip to install requirements from the requirements.txt files. However - I’m running into trouble when I try to add new packages (by adding the package to requirements.txt as a new line and installing again with pip). pip list, or pip freeze both show the new module. But when I add the module to my INSTALLED_APPS and try to import it in my models.py file, Django cannot find it. When I type which python, and which pip, they point to different directories and I think this may be part of the problem but I am stuck. -

Forbidden (CSRF token missing.) error when trying to make a POST request. Using React (Axios) and Django
I've been trying to solve this issue in various ways for awhile now, but every answer I have seen on here has not worked for me yet. I am running React (and Redux) on my localhost:3000, and Django on localhost:8000. I'm very still new to this, but I have seen posts where people have said to include csrf token in the header where the axios post is taken place, but that hasn't worked for me. I've also tried fiddling with settings.py, but none of that has worked as well. This is what I had before researching just to hopefully get a base. Thank you! Here is my /actions/auth.js import axios from 'axios'; import { LOGIN_SUCCESS, LOGIN_FAIL, USER_LOADED_SUCCESS, USER_LOADED_FAIL, } from './types'; // login function export const login = (email, password) => async (dispatch) => { const config = { headers: { 'Content-Type': 'application/json', }, }; const body = JSON.stringify({ email, password }); try { const response = await axios.post( `${process.env.REACT_APP_API_URL}/auth/jwt/create/`, body, config ); dispatch({ type: LOGIN_SUCCESS, payload: response.data, }); dispatch(load_user()); } catch (err) { dispatch({ type: LOGIN_FAIL, }); } }; settings.py """ from pathlib import Path import os # Build paths inside the project like this: BASE_DIR / 'subdir'.

Flask return a proper list object to test in Postman
im currenty doing some work for school; i have a flask app and some postman tests that i have to pass, one of which requests an array of dicts (something like [{dict1}, {dict1},..]) ive been trying to return this: result = [{ "reservationUid": data["reservationUid"], "status": data["status"], "startDate": data["startDate"], "tillDate": data["tillDate"], "book": book_data, "library": library_data }] ive used jsonify(), dumps() + mimetype='application/json', make_response() but nothing really helped, it seems like if i do so, postman wont count that as a json but as an undefined? for example, for return Response(dumps(result), mimetype='application/json') it returns TypeError: Cannot read property 'status' of undefined here is the part of the test where it dies: const response = pm.response.json(); pm.expect(response).to.be.an("array") const reservation = _.find(response, { "reservationUid": reservationUid }) pm.expect(reservation.status).to.be.eq("RENTED") pm.expect(reservation.startDate).to.be.not.undefined pm.expect(reservation.tillDate).to.be.not.undefined tho my response data returns looks like [ { "reservationUid": "f464ca3a-fcf7-4e3f-86f0-76c7bba96f72", "status": "RENTED", "startDate": "2021-10-09", "tillDate": "2021-10-11", ... <some more data here> } ] basically status is actually "RENTED" like required. for django apps that return serializers data with many=True field such tests work just fine, but since u cant just return an array in flask this gets so complicated :( my best solution is to redirect my requests to the django app but isnt … -
Django - create multiple tables from Excel sheets
Forgive me for the relative naivete of this question...I inherited a Django project with zero Django experience myself so I'm trying to keep this thing running while teaching myself the framework at the same time. I have an Excel workbook with multiple sheets and I want to be able to create a table for each sheet. The workbook comes from an API, so I'm using requests to download the workbook. I'm familiar with downloading an Excel workbook and creating a dataframe for each tab, but I'm not sure how to pass multiple dataframes on to multiple models within Django without making the get request one time for each of the sheets. Here is an example of my update command for a flat file get request: import os import pandas as pd import sys import json from datetime import date, datetime from utils.update_dataset_command import UpdateDatasetCommand class Command(UpdateDatasetCommand): app_label = 'my_app' model_name = 'table1' def pull_data(self, fields): # Pull the dataset from get_request = requests.get('URL.csv') dataframe = pd.read_csv(get_request.content) return dataframe What I'm trying to achieve is to be able to do something like: Class Command(UpdateDatasetCommand): app_label = myapp model_names = ['table1', 'table2', 'table3'] def pull_data(self, fields): get_request = requests.get('URL.xlsx') Excel = pd.ExcelFile(get_request.content) … -
Prefetch query with relational conditions - Django
I'm trying to make a request that prefetch all the data to reduce the amount of requests to my database. I'm using the prefetch_related() method and the Prefetch object class to tell what to load in the same request, here is my code: pairs_queryset = Pair.objects.filter(quote_id="2781", last_price__isnull=False) \ | Pair.objects.filter(quote_id="825", last_price__isnull=False) \ | Pair.objects.filter(quote_id="3408", last_price__isnull=False) queryset = Portfolio.objects.prefetch_related( Prefetch('connections__wallets__currency__metadata__images'), Prefetch('connections__wallets__currency__base_pairs', queryset=pairs_queryset), ).get(id=portfolio_id) data = Serializer(queryset).data My problem here is that I have multiple base_pairs in my database that depends on the Connection model. So I would like to add a filter that depends on a value contained in on of the previous models (i.e. connection) of the prefetch. As connections is a set (multiple values), I want that the following: connections__wallets__currency__base_pair retrieve the base_pair related to the connection currently fetched. Here is a diagram: connections__wallets__currency__base_pairs ^ |_______________________________| depends on I read the documentation and couldn't find any solution. Is it possible? -

how to update a form inside a class based detail view?
I created a survey form for each user which the staff user can fill it for them. I created a detail view and added formMixin just like this: class ScientificInfoView(FormMixin, DetailView): model = ScientificInfo template_name = 'reg/scientific-info.html' form_class = ScientificInfoForm def get_success_url(self): return reverse('scientific-info', kwargs={'pk': self.object.pk}) def get_context_date(self, **kwargs): context = super(ScientificInfoView, self).get_context_data(**kwargs) context['form'] = ScientificInfoForm() return context def post(self, request, *args, **kwargs): self.object = self.get_object() form = self.get_form() if form.is_valid(): return self.form_valid(form) else: return self.form_invalid(form) def form_valid(self, form): f = form.save(commit=False) f.user = self.object.user f.save() return super(ScientificInfoView, self).form_valid(form) it works just fine but I want the staff to be able to edit and update these forms as well. If I click on the object and refill the form it wouldn't update the previous one but makes a new object for that user. I don't want that. I need to somehow change this view to update the view if the user has this object already. I created a dashboard that divides those who have filled forms and those who haven't. I want the filled ones to get redirected to the update view, not the detail view I wrote. is there a way to update this one or should I create … -

guidance with Dj-rest-auth and implementing google login in flutter app
I have a flutter application with a DRF back end. currently using Dj-rest-auth for regular authentication (token). I'm at a point where I'd like to implement social authentication (specifically Google). I searched a few resources but still don't quite get the workflow. https://github.com/iMerica/dj-rest-auth/pull/336/commits/8f5cc65049c4bcb0c650bde707f5023013497b20 my guess is: you set up your application on google cloud console. You make a request to get an "access token" to the google auth on the Frontend (in my case flutter) send that access token to your Back end - django to confirm. which then sends back a regular token for authentication? Any guidance would be appreciate. -
Django intermittent multithread shared queue
I am trying to solve this simple problem in django the Correct Way Worker1(thread): django connected to serial device streaming data ~ 1kb/s Consumer1(thread): reads FIFO (queue) and processes the data as it enters the fifo **the consumer will run intermittently How do I pass the queue object to the newly created consumer if the worker is already running with its own queue?
