django nginx getting csrf verification error in production over http
I've just deployed my django project on AWS with nginx. Everything works well except for when when I try to make any POST requests (over just http), I get the error: "Forbidden (403) CSRF verification failed. Request aborted." CSRF verification works if I run my server directly using Django which leads me to think that I did not set up my nginx.conf correctly. Can someone give some guidance as to how I can configure nginx to work with csrf? Here's my current config: #nginx.conf upstream django { # connect to this socket server unix:///tmp/uwsgi.sock; # for a file socket #server 127.0.0.1:8001; # for a web port socket } server { # the port your site will be served on listen 80; root /opt/apps/site-env/site; # the domain name it will serve for server_name mysite.org charset utf-8; #Max upload size client_max_body_size 75M; # adjust to taste location /media { alias /opt/apps/site-env/site/media; } location /static { alias /opt/apps/site-env/site/static; } location / { uwsgi_pass django; include /etc/nginx/uwsgi_params; proxy_pass_header X-CSRFToken; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto http; proxy_set_header X-Real-IP $remote_addr; proxy_set_header HOST $http_host; proxy_set_header X-NginX-Proxy true; } } I've also turned off both SESSION_COOKIE_SECURE and CSRF_COOKIE_SECURE in my django settings.

Upload and process a remote file called by an API REST call with a Django backend
The application is written in Django. I need to A) upload a file (an Excel spreadsheet) from a remote location (it could be via HTTP or SFTP), B) triggered by a signal/API call issued by a remote client. The file will be then processed (it could be synchronously or asynchronously) to update a database in the backend (this latter part is already working and is implemented with a file which is read locally). What is the best strategy, and tools to use to solve both points A) and B) above? -
Can't import rest_framework in Django
I'm trying to stand up a Django site and I am attempting to setup Report_builder with that. I just got the front end of report builder to work but it is not returning any data. I suspect the problem is with my rest framework. The settings did not auto create and now when I try to import it to create a serializer restframework is not recognized at all. Here is my settings page: REST_FRAMEWORK = { 'DEFAULT_AUTHENTICATION_CLASSES': ( 'rest_framework.authentication.SessionAuthentication', ), } Did I possibly install rest framework in the wrong place or?? I have the latest version. -

Python Django Rest Framework UnorderedObjectListWarning
I upgraded from Django 1.10.4 to 1.11.1 and all of a sudden I'm getting a ton of these messages when I run my tests: lib/python3.5/site-packages/rest_framework/pagination.py:208: UnorderedObjectListWarning: Pagination may yield inconsistent results with an unordered object_list: <QuerySet [<Group: Requester>]> I've traced that back to the Django Pagination module: https://github.com/django/django/blob/master/django/core/paginator.py#L100 It seems to be related to my queryset code: return get_user_model().objects.filter(id=self.request.user.id) How can I find more details on this warning? It seems to be that I need to add a order_by(id) on the end of every filter, but I can't seem to find which code needs the order_by added (because the warning doesn't return a stack trace and so it happens randomly during my test run). Thanks! -
Django social_auth for facebook no longer working
I had social_auth set up with facebook log-in for a Django app. However, recently it stopped working (even though I made no changes to the code as far as I recall). Before it worked fine, but now when I try to log in I get the following error from the Django debug screen that results: Through some further debugging I realized that the "response" variable in the facebook.py file when running the auth_complete function was non-empty, but then the parsed_response variable does not parse the response correctly and thus ends up empty. Thus in the facebook.py file of the social authentication backend, I changed the following line of code: parsed_response = cgi.parse_qs(response) access_token = parsed_response['access_token'][0] if 'expires' in parsed_response: expires = parsed_response['expires'][0] To the following: import ast parsed_response = ast.literal_eval(response) access_token = parsed_response['access_token'] if 'expires' in parsed_response: expires = parsed_response['expires'] And it works! However, this seems like a hack to me. After scouring the web for people experiencing a similar problem with the social_auth login, I couldn't find any relevant posts. Similarly, it seems odd that it just stopped working all of a sudden as it was working this entire time. Thus, I feel like although this is a working … -
Django 1.11: Can't get ManyToManyField to work

How are ManyToMany payloads kept?? Secondly, my goal is to have multiple addresses for Users. I want Users to have multiple "Addresses" (and not each address having one User) because other models can have addresses too. I don't want … -

Django ManyToMany intermediary model, move relationship
So, after reading the documentation regarding intermediary model's, it seems that there's no built-in way of changing one side of a relationship without clearing all relationships with that side. But how can I do this anyway? I was thinking that I may have to store all of the relationships in an array / object so I can recreate them when needing to change 1 or more relations. My Models: Company Camera CompanyCameraRelationship I would want to change the relationship between Company 1 and Camera 1 to Company 1 and Camera 2. So in order to do this, I must clear all relationships between Company 1 and other Cameras? Any thoughts would be greatly appreciated! -

Django NullBooleanField - Why does 'Unknown' always default to "No" among "Unknown", "Yes" or "No" choices?
I have a model field that is a NullBooleanField with blank and null set to True. I'm calling this model in my ModelForm with default widgets. The form renders the NullBooleanField as a dropdown box with 3 values: Unknown, Yes and No. Choosing a Yes or No will set the field to their respective choices, but choosing Unknown also sets it to No. How do I make it so that choosing Unknown will result in the field being set to Null or None? This is my code: My models.py: Class ProductDetail(models.Model): in_stock = models.NullBooleanField(blank=True, null=True, default=None) quick_ship = models.NullBooleanField(blank=True, null=True, default=None) My Forms.py: class ProductMessageForm(ModelForm): class Meta: model = ProductDetail fields = ('in_stock','quick_ship') -

Molar-mass-calculators like the one from chempy or molmass.py by Gohlke both have problems with formulas like (Mg2(Si2O6))0.94 because they can't parse .94 after the parenthesis (or I'm blind). I found this regex (https://regex101.com/r/vE6nC7/1) which is almost perfect but has problems with formulas like (Mg2(Si2O6))0.94(Fe2(Si2O6))0.06 with two times double parenthesis (just (Fe2(Si2O6))0.06 works). It works if I substitute the outer parenthesis with []. There should be a nice regex for this problem with just multiple (), or? I played with regex101 but couldn't find something that works. Any help? greetings, philipp -

pyplot crashing on plt.figure() in macOS
I repeatedly get RuntimeError: main thread is not in main loop when I call plt.figure(). This is in a charting function that creates charts based on user data in a django webapp. I've seen a warning on IDLE in python 3.4 that my version of Tcl/Tk may be unstable which links to http://www.python.org/download/mac/tcltk/ for more information, but this did not provide any guidance on how to determine what version I was running in a venv, or how to update the version in the venv. This error only happens in my mac OS environment. Not sure if I'm using matplotlib wrong, or if I need to update my environment. If I need to update, I have no idea how to go about this with a virtual environment. Code: def visualize(frictionloss): """ Input: an instance of a FrictionLoss model, Return: a bar chart of the losses in b64 encoded image """ # 6 bars ind = np.arange(6) width = .65 # load psi lost in each section to a bar to show losses1 = (frictionloss.ug_1_loss, frictionloss.ug_2_loss, frictionloss.riser_loss, frictionloss.bulk_main_loss, frictionloss.cross_main_loss, frictionloss.head_1_loss) # additionally, show each head loss to later stack on top losses2 = (0, 0, 0, 0, 0, frictionloss.head_2_loss) losses3 = (0, … -
Django survey with forms
I am building a survey tool and I'm wondering how would I continue with this or if my current solution is even the proper way to do it. Admin of the page may add or remove questions from questionnaires, so if I have understood it, I can't use ModelForms to handle the form data? A form may consist of 5 multichoice questions and 2 free text questions or any other amount of different types of questions so there isn't any fixed type of questionnaire How do I then save the values of the form as I do not have a model to use? Is this even possible to achieve without using a model for the form? Thank you for any input in advance. views.py from django.shortcuts import render from .models import Questionnaire, Question, Answer def index(request): all_questionnaires = Questionnaire.objects.all() all_questions = Question.objects.all() return render(request, 'questions/index.html', locals()) def questionnaire_detail(request, questionnaire_id): questionnaire = Questionnaire.objects.get(id=questionnaire_id) questions = Question.objects.filter(questionnaire=questionnaire) return render(request, 'questions/questionnaire.html', {'questionnaire': questionnaire, 'questions': questions}) def calculate(request): if request.method == 'POST': pass models.py from django.db import models MC = 'MC' CN = 'CN' TX = 'TX' CATEGORY = ( (MC, 'Multichoice'), (CN, 'Choose N'), (TX, 'Text'), ) VALYK = '1' VALKA = '2' … -
List Django urlpatterns in Sphinx docs
I'm using sphinx to document my django app. Using sphinx-apidoc I created documentation for the whole app application, but I need to add urlpatterns from app.urls to the documentation. Currently docs for this module contains only its name, and I want to add url regexes and corresponding views information. I'd appreciate any advice on how to do that.
