I have a query; I would be using a explicitly defined primary key field in my user table, what I want is to attach a number like '111'+ i as the primary key where i is auto incremented... but if the server stops by some chance, I would have to reload i, so I would have to save the value of i in database after each run also i would be reading i each time from database Concerns: 1. What if before i is saved server crashes, so the value of I would be corrupted 2. If I has been read once, can I be able to not read it at each run My use case is : 1. I have one US server which is seperated by UK server, but I want to have a global server too where US and UK users are both present

TypeError at /cart/ expected string or bytes-like object

I would try checking which line is causing that error in the view method, using print statements or something

order, created = Order.objects.get_or_create( customer=customer, complete=False)

order, created = Order.objects.get_or_create( customer=customer, complete=False)

Hey people! I want to implement 3 models this way: class Item(models.Model): title = models.CharField(max_length=200) price = models.DecimalField(max_digits=7, decimal_places=2) class Variation(models.Model): item = models.ForeignKey(Item, on_delete=models.CASCADE) color = models.CharField(max_length=8) class Image(models.Model): variation = models.ForeignKey(Variation, on_delete=models.CASCADE) image = models.ImageField(upload_to='images/') Now, in the Django Admin I want the user to be able to create an 'Item' object, where there should be an inline 'Variation' and also the ability to add variable number of images for each variation. But Django doesn't support nested inlines. Here's my admin.py: from django.contrib import admin from .models import Item, Variation class VariationInline(admin.StackedInline): model = Variation extra = 1 @admin.register(Item) class ItemAdmin(admin.ModelAdmin): fieldsets = [ (None, {'fields': ['title', 'price']}) ] inlines = [VariationInline] What could be the solution to this?

Did you import Sneaker class?

Guys anyone ????

if I am going to create a full api-based web application, wouldn't be Flask better than Django? I read on internet Flask has a better performance over Django but I wanted to ask you guys, as I am currently using Django but without API implementation.

order, created = Order.objects.get_or_create( customer=customer, complete=False)

solved issue

Ya, flask is faster than django but it wont have as many inbuilt functions as of django. Like Models , users panels , admin panel

Deploying to Heroku can be painfull (first time) My cheat-sheet includes following bits: — do you have gunicorn (or another server) in pipfile? — did you migrate DB? — does it have all required ENVs? — does it start in production? (provide full error if you want some help)

Can i make api request on heroku? Using requests library? I tried in pyanywhere but it was not whitelisted on their server.
