Django: (2013, 'Lost connection to MySQL server during query') in my deployed app but not in my locally ran version
I deployed my Django app on Google App Engine and I am getting this error for one of my Select queries. The MySQL DB is hosted remotely, the locally ran(runserver) app can connect to it with no issues. Things I've tried: Remade the DB and tables Raised the timeout variables in MySQL Raised the packet size The related query and the snippet: SELECT Marketplace from marketplace # Getting items to populate the ChoiceField with connections[db_connection].cursor() as c: c.execute("SELECT Marketplace from marketplace") marketplace = c.fetchall() for k in marketplace: for v in k: mkt_choices.append(tuple([v, v])) mkt_choices = tuple(mkt_choices) Number of entries found is 26, so size shouldn't be an issue I use 2 DB connections I expect this to be one of many queries to raise this issue so I would like to know what I am doing wrong.

DJANGO ecommerce website help needed. Different orders have same OrderItems
So I am following this tutorial on YouTube to make an eCommerce website using DJANGO but the problem is that now that I'm done with the tutorial I realize something is wrong. So whenever i make a new order, that order has the order items in it, as Order model has a manytomanyfield with OrderItem. So I make one order and save it. But if i make a second order and then save it, the first order's order items will become equal to the second order which shouldn't happen. I've been at this for 4 hours now and I don't know what to do so I'd appreciate your help. Both Orders have different ref_codes so at least that is working properly. Screenshot of admin view of both orders are attached.

Django app on Nginx + Gunicorn. POST request failure - "500 Internal Server Error". Why?
I have a CentOS 7 VDS server with a Django app running on Nginx + Gunicorn setup. This application should be able to receive POST requests with medium size .docx files or large amount of text via textarea. And my problem is whenever I make POST request with files of any size OR with text larger than certain point (approx. 3/4 of A4 page) Nginx instantly throws 500 Internal Server Error. It does work with smaller texts in textarea just fine, though. I figured Nginx doesn't even send any request to Gunicorn server. Here's my nginx.conf file: worker_processes auto; error_log /var/log/nginx/error.log; pid /run/nginx.pid; # Load dynamic modules.

Is there another way to annotate Count/Sum in existing queryset?
Let me illustrate the problem with canonical models Book&Author. Here is the view: class Report(ListView): ... def get_queryset(self): ... # calculating of filters return Book.objects.filter(status='published', date= ... a bunch of filters) So that we have a queryset with all necessary filters. It might be used in another functions, for example, to get the number of books: def books_number(self): qs = self.get_queryset() return qs.count() or cost of all these books: def summa(self): qs = self.get_queryset() return qs.aggregate(Sum('price')) Now, I want to get number of books by each Author and their costs and I would be happy with something like this: def authors_info(self): qs = self.get_queryset() return Author.objects.annotate(books_number=Count( use qs somehow ... ), books_cost = Sum( use qs over field 'price' somehow ...) ) but I haven't yet found a way to do that. Well, to get it working I used this: def authors_info(self): ... # calculating of THE SAME filters AGAIN q_ = Q(status='published', date= ... a bunch of filters) count_ = Count('book', filter=q_) sum_ = Sum('book__price', filter=q_) return Author.objects.annotate(books_number=count_, books_cost=sum_) but it definitely contradicts with DRY principle. Is still there more tidy way to get queryset in one function and to annotate it in another function? -

Django allauth Sendgrid django error IncompleteRead(0 bytes read, 116 more expected)
I am using Django allauth to verify users after email however I keep getting the error: IncompleteRead(0 bytes read, 116 more expected) Currently, my view for the signup view for handling after post request is: if request.method == 'POST': form = SignUpForm(request.POST) if form.is_valid(): storage = messages.get_messages(request) for _ in storage: pass for _ in list(storage._loaded_messages): del storage._loaded_messages[0] user = form.save(commit=False) #user.is_active = False user.save() send_email_confirmation(request, user, True) return redirect('main:user_login') My Sendgrid settings is: SENDGRID_API_KEY = 'myaapikey' EMAIL_HOST = 'smtp.sendgrid.net' EMAIL_PORT = 587 EMAIL_USE_TLS = True EMAIL_HOST_USER = 'my username' EMAIL_HOST_PASSWORD = 'mypassword' DEFAULT_FROM_EMAIL = DEFAULT_EMAIL And my allauth is: AUTH_USER_MODEL = 'main.Profile' ACCOUNT_EMAIL_VERIFICATION='mandatory' ACCOUNT_UNIQUE_EMAIL = True ACCOUNT_EMAIL_REQUIRED= True ACCOUNT_AUTHENTICATION_METHOD = 'email' ACCOUNT_LOGIN_ON_EMAIL_CONFIRMATION = False ACCOUNT_EMAIL_SUBJECT_PREFIX = "JoinCampus " SOCIALACCOUNT_ADAPTER = 'main.adapters.SocialAccountAdapter' When I use the Django Email backend the email is being sent however when I use Sendgrid it doesn't work. However, if I use sg = SendGridAPIClient(os.environ.get('SENDGRID_API_KEY')) The emails are being send successfully.
