Django: is_valid() method is always false why?
Everytime i get the stu_name variable value from form without using is_valid() function then stu_name is always return value enter by user but with is_valid() stu_name is always None.I do some experiments and i found that is_valid() is always return false but why? This is views.py file code. from django.shortcuts import render from django.http import HttpResponse from .models import student from .forms import student_data def my_data(request): stu_name=None myform=student_data(request.POST) if (request.method=="POST" and myform.is_valid()): stu_name=myform.cleaned_data['user'] else: myform=student_data return render(request,'show.html',{'student':stu_name}) This is my html file where the form code is written. <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>Document</title> </head> <body> <div> <form action="/payment/show/" method="POST"> {% csrf_token %} <label for="">Name</label> <input type="text" name="user" required> <label for="">ID</label> <input type="number" required> <label for="">Address</label> <input type="text" required> <button type="submit">Add Me</button> </form> </div> </body> </html> forms.py file code. from django import forms class student_data(forms.Form): name=forms.CharField(widget=forms.TextInput,max_length=20) id=forms.IntegerField(widget=forms.NumberInput,max_value=6) address=forms.CharField(widget=forms.TextInput,max_length=50) -

Intermediate data - Class methods vs functions [closed]
After my app receives data from an external source a lot of functions are called on the data. This to make normalizations, calculations etc. before the data is saved in a Model. What is best practice? To use functions to transform the data e.g. intermed = normalize(intermed intermed = calculate_totals(intermed) To create a special Class with methods e.g. intermed = IntermediateClass() intermed.title.normalize() To create intermediate fields in the ModelClass, that don't get saved to the db. mymodel.calculate_temp_totals() mymodel.save() Any ideas. Thanks in advance. -

Python Django safe increment / decrement
I want to build an api for a article amount management system for my store. With this I need to safely increment or decrement the amount of an article and log it with the user who executed it to the database. It should look like this: from django.db import models from django.contrib.auth.models import User class Article(models.Model): name = models.CharField(...) amount_in_store = models.IntegerField(...) ... class ArticleAmountChange(models.Model): article = mdoels.ForeignKey(Article, ...) amount_change = models.IntegerField(...) user = models.ForeignKey(User, ...) ... But how can I guarantee the amount_in_store will always be the sum of all amount_changes for this article and still have a great performance? So I don't want to query over all ArticleAmountChange and sum the amount_changes because after some time of use there will be thousands of ArticleAmountChanges. Can you help me? -

Django Dev Server Module Whitenoise Not found
I'm trying to use Whitenoise in dev as suggested per the docs, but when I run the django dev server with the whitenoise module loaded in INSTALLED_APPS and MIDDLEWARE, as such: INSTALLED_APPS = [ 'django.contrib.admin', 'django.contrib.auth.backends.ModelBackend', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', 'rest_framework', ...other MIDDLEWARE = [ 'django.middleware.security.SecurityMiddleware', 'whitenoise.middleware.WhiteNoiseMiddleware', 'django.contrib.sessions.middleware.SessionMiddleware', 'django.middleware.common.CommonMiddleware', 'django.contrib.auth.middleware.AuthenticationMiddleware', 'django.contrib.messages.middleware.MessageMiddleware', 'django.middleware.clickjacking.XFrameOptionsMiddleware', ] Yet when I make sure the module is installed using pip install whitenose, I get the error: ModuleNotFoundError: No module named 'whitenoise' Yet when I try pip install whitenoise I get: Requirement already satisfied: whitenoise in /Users/USERNAME/Development/venv/yourdash/lib/python3.7/site-packages (5.0.1) So I'm forced to run during dev without whitenoise. But because of this, I do run into issues as a result of different static files between dev/prod. So how can I ensure whitenoise will run while using the django dev server? -

Django - which create() method to override before saving incoming data as object
I have the following model in my models.py file: class Video(models.Model): created = models.DateTimeField(auto_now_add=True) text = models.CharField(max_length=100, blank=True) video = models.FileField(upload_to='Videos/', blank=True) gif = models.FileField(upload_to='Images/', blank=True) class Meta: ordering = ('created', ) Before Django creates an instance of this model, I want to set the gif field on the Django site.

Nginx rewrite after proxy pass
I am using Django + Gunicorn to serve files and nginx as a static file server, you can see a part of the configuration file below location /static/ { root /some/folder; } location / { proxy_pass http://127.0.0.1:8080; proxy_set_header Host $host; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Real-IP $remote_addr; } What I want to do is to access static files without putting /static/ into url. As I see it, if there is initially no /static/ in the url, than the request should be passed down to Django (/). If there is /static/, than then it should be cut away and the appropriate static file should be served.
