How to connect local React app to local REST API for production
I have a system where I want several tablets to connect to a local server on a local network. It would be nice to use react native on the tablets and connect to a local Django REST API on an apache server. I don't want this system touching the web whatsoever (totally offline). Is there a way to do this given self-signed SSL certs are supposedly development only? This networking part of it is new to me. -

Django, OOP question to deal with EAV and complex attributes tables/models for diverse products
I have this model and I want to run select_related query for the category related product's attributes. class auction_product(models.Model): title = models.CharField(max_length=64) date_added = models.DateField(default=timezone.now) user = models.ManyToManyField(User, through='product_ownership', related_name='product_user') category = models.ForeignKey(Categories, on_delete=models.CASCADE) condition = models.CharField(max_length=5, choices=[('N', 'New'), ('U', 'Used')]) description = models.CharField(max_length=4096) product_bid = models.ManyToManyField(User, through='bid', related_name='product_bid') product_comment = models.ManyToManyField(User, through='comment') album = models.OneToOneField(ImageAlbum, related_name='product_model', blank=True, null=True, on_delete=models.CASCADE) class extra_vehicle_attributes(auction_product): product = models.OneToOneField('auction_product', primary_key=True, parent_link=True, on_delete=models.CASCADE, related_name="vehicle_attributes") make = models.CharField(max_length=128) model = models.CharField(max_length=128) year = models.IntegerField() mileage = models.IntegerField() class extra_pc_attributes(auction_product): product = models.OneToOneField('auction_product', primary_key=True, parent_link=True, on_delete=models.CASCADE, related_name="pc_attributes") processor = models.CharField(max_length=264) ram = models.FloatField() brand = models.CharField(max_length=64) motherboard = models.CharField(max_length=264) case = models.CharField(max_length=264) screen_size = models.FloatField() weight = models.FloatField() Now in the views.py for instance I am running this code below, but it is getting really tedious to write because each time I have to write .vehicle_attributes or pc_attributes or whatever attributes I may have and write it after the object in python code. Is there a way where I can get all the select_related mentioned fields properties without having to write like .vehicle_attributes for each object? I just want python to spit out all the possible fields auction_product may belong to its attributes foreign table without having … -
Uploading duplicated files with Django when reloading page
I'm trying to upload some files and I'm having problems with duplication. To uploading the file I do the following: views.py: from django.core.files.storage import FileSystemStorage def contView(request): if request.method == 'POST' and request.FILES.get('myfile'): myfile = request.FILES['myfile'] fs = FileSystemStorage() filename = fs.save('uploads/'+myfile.name, myfile) uploaded_file_url = fs.url(filename) # Return template_name ='cont/mainCont.html' context = {} return render(request, template_name, context) Template: <form method="post" enctype="multipart/form-data">{% csrf_token %} <div class="input-group"> <input type="file" name="myfile" class="form-control"> <span class="input-group-btn"> <button class="btn btn-default" type="submit">Importar</button> </span> </div> </form> The upload works perfectly but when I refresh the page it upload the same file again. Why is this happening? I need to empty something? Thank you very much! -
Use Twitter API in Celery task - need to use access_key and access_secret from auth user
I have the following function in my views.py that will send me the authorised user's key tokens. I can then manually amend these tokens for my Twitter API function locally to run the program. def like(request): oauth = tweepy.OAuthHandler(CONSUMER_KEY, CONSUMER_SECRET) access_key = request.session['access_key_tw'] access_secret = request.session['access_secret_tw'] send_mail( 'Auth Codes', # subject 'access key - ' + os.environ['oaccess_key'] + '\n' + 'access_secret - ' + os.environ['oaccess_secret'], # message DEFAULT_FROM_EMAIL, # from email [DEFAULT_FROM_EMAIL], ) return render(request, "home.html") However having to do this manually isn't great and for security reasons I'd rather not have them emailed. I want to push the function to a celery task so that I don't need the sendmail() at all. My celery task would look like this after liking.delay() being called within like() - @app.task(bind=True) def liking(self): oauth = tweepy.OAuthHandler(CONSUMER_KEY, CONSUMER_SECRET) oauth.set_access_token(access_key, access_secret) api = tweepy.API(oauth) ** Rest of my code using the Twitter API ** I have tried setting the access_key and access_secret as environmental variables but they do not import to the celery.py. Is there any way that I'm missing that can enable this to work? -

Django - Group by Count of Foreign Key
I have two models like so: models.py class Subscription(...): is_active = models.BooleanField(...) class Order(...): subscription = models.ForeignKey('Subscription', related_name='orders', ...) ... I want to know: How many subscriptions have x number of orders (i.e. 7 subscriptions with 1 order, 5 subscriptions with 2 orders, etc.) The average number of orders across all of my subscriptions (i.e. 2.2 orders) I can susccesfully annotate the number of orders to a subscription queryset, but I am having trouble grouping the queryset by like 'number_of_orders' from there: views.py from django.db.models import Count queryset = Subscription.objects.filter(is_active=True).annotate(number_of_orders=Count('orders') queryset = queryset.values('number_of_orders') I've tried: queryset = queryset.order_by('number_of_orders').aggregate(count=Sum('number_of_orders')) which doesn't group my subscriptions correctly, and: queryset = queryset.order_by('number_of_orders').annotate(count=Sum('number_of_orders')) which fails with this error: Cannot compute Count('number_of_orders'): 'number_of_orders' is an aggregate Ideally, I am looking for the result to be in a form that I can pass to a bar chart in chart.js, something like: data = [ {"subscriptions_with_1_order" : 5}, {"subscriptions_with_2_orders" : 3}, {"subscriptions_with_3_orders" : 3}, ... ] or more preferably (where x is the number of orders and y is the count of subscriptions with that many orders): data = [ {"x" : 1, "y" : 5}, {"x" : 2, "y" : 3}, {"x" : 3, "y" : 3}, … -

docker React, django(gunicorn), nginx reverse proxy with https give Bad request 400 on accessing backend APIs

Django Rest framework as Single Sign On
I have created DRF application with Django OAuth Toolkit (DOT) Rest Application with oAuth2 flow. I was planning to use these api's as Single Sign On (SSO). For javascript client it is working fine with "authorization_code" grant type which is returning me access token and refresh token and with those I can authorize and authenticate my javascript application. But for another Django application I am stuck to do the same. It has its own user database and default authentication backend. I want to authenticate users with SSO user database and create a session on successful login into SSO application (DRF application in my case). I want to achieve following: In Django Application I click on login link. It redirect me to SSO login page and ask me to provide user credentials. On successful login I redirect back to Django application and land on dashboard page after auto login. If anybody can spare some time and let me know if I am getting wrong anywhere it will be helpful. Thank you in advance. -

How to get Sphinx doctest to reset the Django database after each test?

Why isn't Admin detecting these models?
I'm making a kanban app to learn Django, and I've run into this problem: Admin doesn't pick up the models I've created. I had an existing Postgresql database with the necessary tables created, and autogenerated the models with python manage.py inspectdb. These are the relevant models: class Boards(models.Model): name = models.CharField(max_length=50) description = models.CharField(max_length=255) class Meta: managed = False db_table = "boards" class Columns(models.Model): name = models.CharField(max_length=25) board = models.ForeignKey(Boards, models.CASCADE, db_column="board") class Meta: managed = False db_table = "columns" class Cards(models.Model): name = models.CharField(max_length=140) description = models.TextField() deadline = models.DateTimeField() column = models.ForeignKey("Columns", models.CASCADE, db_column="column") class Meta: managed = False db_table = "cards" And this is the content of admin.py: from django.contrib import admin from .models import Boards, Columns, Cards admin.site.register(Boards) admin.site.register(Columns) admin.site.register(Cards) Just in case, these are the INSTALLED_APPS in settings.py: INSTALLED_APPS = [ "django.contrib.admin", "django.contrib.auth", "django.contrib.contenttypes", "django.contrib.sessions", "django.contrib.messages", "django.contrib.staticfiles", "rest_framework", ] Thanks in advance for the help! -
Django forms - how to select which model to create in the form
I have some loosely similar models that are separate but share a parent through concrete inheritance. Two of the models have the same form, so I want to be able to select which model to create within the form. To clarify, I want one of the fields to be a select field and the value of that field should tell the form which model class it is going to be creating. I have been trying to research this but I cannot find any related questions and all of my google searches are littered with "model form" and "model choice field" results. -
