Djangos data cannot be imported into the database, is my code wrong?
I am new to Django, and I'd like to ask some questions I used the model layer to create the model with fields in it,it can create user_id,movie_id field in the database. class Rating(models.Model): user_id = models.CharField(max_length=16) movie_id = models.CharField(max_length=16) rating = models.DecimalField(decimal_places=2, max_digits=4) rating_timestamp = models.DateTimeField() type = models.CharField(max_length=8, default='explicit') def __str__(self): return "user_id: {}, movie_id: {}, rating: {}, type: {}"\ .format(self.user_id, self.movie_id, self.rating, self.type) class Cluster(models.Model): cluster_id = models.IntegerField() user_id = models.IntegerField() def __str__(self): return "{} in {}".format(self.user_id, self.cluster_id) Execute this statement using Python xxx.py,I want to populate the database but it doesn't work import os import urllib.request import django import datetime import decimal from tqdm import tqdm os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'mysite.settings') django.setup() from analytics.models import Rating def create_rating(user_id, content_id, rating, timestamp): rating = Rating(user_id=user_id, movie_id=content_id, rating=decimal.Decimal(rating), rating_timestamp=datetime.datetime.fromtimestamp(float(timestamp))) rating.save() return rating def download_ratings(): URL = 'https://gitee.com/zhangyoushang/wokkk/blob/master/latest/ratings.dat' response = urllib.request.urlopen(URL) data = response.read() print('download finished') return data.decode('utf-8') def delete_db(): print('truncate db') Rating.objects.all().delete() print('finished truncate db') def populate(): delete_db() ratings = download_ratings() for rating in tqdm(ratings.split(sep="\n")): r = rating.split(sep="::") if len(r) == 4: create_rating(r[0], r[1], r[2], r[3]) if __name__ == '__main__': print("Starting MovieGeeks Population script..." ) populate() But I found that my database was empty and there was no data in it. … -

request.POST data not in forms' cleaned_data
When creating a new instance of my model I fail to transfer the data from request.POST into the forms clean method on is_valid(): class cView(TemplateView): template_name = "store/new_product.html" def post(self, request, *args, **kwargs): print(request.POST) # correctly prints <QueryDict: {'number': ['8'], 'name': ['myproduCT'], 'price': ['2']}> obj = Product.objects.create(number = request.POST["number"], data = {}) form = ProductForm(request.POST, product = obj) form.is_valid() # validates to True The form looks like: class ProductForm(forms.Form): class Meta: model = Product fields = ["id", "number", "data"] def __init__(self, *args, **kwargs): product = kwargs.pop("product") super().__init__(*args, **kwargs) self.fields["number"] = forms.IntegerField(required = True) for key in product.data.keys(): self.fields[key] = forms.Charfield(requiered = False) def clean(self): cleaned_data = super().clean() print(cleaned_data) # only prints {'number': 8} ... Why is the rest of the request.POST data not in cleaned_data? Is this happening because the forms __init__() method gets an empty product.data attribute? How would I avoid this, when the Product is just now created and not filled with (validated) data? Product looks like this: class Product(models.Model): data = models.JSONField() number = models.PositiveIntegerField() -
Django download the right file from model
I created a web app that allows users to extract geometrical and other data from a 3D model in ifc format. So the user uploads the 3D model, the app gives him some basic info about the model and lets the user decide which data he wants to download in which format (xlsx or csv) For the uploaded file I have an upload form from the model. And then when the user decides what he wants to download I retrieve the uploaded file using the objects.latest query. But that can lead to problems, right? If multiple users are uploading files at the same time it can lead to a mismatch. What would a better practice of solving this problem be? How do I associate the page visitor withe the file he uploaded? -

Stripe: 'payment_intent.succeeded' is also triggered when subscription gets renewed
I have two APIs for Stripe webhooks in my backend (Django). "Subscription" webhook: /api/subscriptions/webhook/ "Add Balance to Wallet" webhook: /api/wallet/webhook/ In the subscription webhook, I listen for invoice.paid and invoice.payment_failed events and in the wallet webhook I listen for payment_intent.succeeded event. The problem is whenever the subscription webhook gets called, the payment_intent.succeeded event is also triggered for the wallet webhook. I think that's because payment intents are also created for subscription as well. I need a way to differentiate these two (one-time payment [aka add balance to wallet] and subscription) so I don't end up with extra credit in user's wallet whenever their subscription get renewed. -

How to render error or validation messages to ModelForm in 2022
I've spent several hours researching on the internet, especially the official Django documentation, but still it is not clear to me which is the best option in 2022 (since almost all questions I read on SO are > 6 yo) and there are diverse opinions on whether crispy forms is better or not. Is still crispy forms a recommended option? How can I (and what is the most recommended way to) get the typical validation error messages? Like: "this field is mandatory" or "this input accepts numbers only"? I've seen some Django pages using those default messages but I don't know how to show them in my ModelForm fields.
