To my code, which records a contact from the form and adds it to the db, need to add get_or_create, or write another condition (if there is a contact with such a phone — update, no - add), but i'm do it for the first time, please, I'll be glad to read solution to my problem and a brief explanation ♡

if form.is_valid():
form.save()

return redirect('/')
return render(request, 'app/main.html', { 'form':form } )

You can implement this with:
def main(request):
if request.method == "POST":
form = Forms(request.POST)
if form.is_valid():
Form.objects.get_or_create(
phone=form.cleaned_data['phone'],
defaults={'name': form.cleaned_data['name']}
)
messages.success(request, 'Form has been submitted')
return redirect('/')
else:
form = Forms()
return render(request, 'app/main.html', { 'form': form })
You must be careful however since this means that a user might edit data of another user. Perhaps it is thus worth to check if the (logged in) user has rights to update that item.

I am a beginner at Django. I want to let users fill in Form and upload a file to the specific folder at the same time, and get the form value they filled in.
Here is my forms.py
from django import forms
class UserForm(forms.Form):
first_name= forms.CharField(max_length=100)
last_name= forms.CharField(max_length=100)
email= forms.EmailField()
file = forms.FileField() # for creating file input
My functions.py (this function is to let users upload a file to the path 'mysite/upload/'.)
def handle_uploaded_file(f):
with open('mysite/upload/'+f.name, 'wb+') as destination:
for chunk in f.chunks():
destination.write(chunk)
My index.html
<head>
<meta charset="UTF-8">
<title>User Information Form</title>
</head>
<body>
<form action="" method="POST">
{% csrf_token %}
{{ form.as_p }}
<input type="Submit" name="submit" value="Submit"/>
</form>
{% if submitbutton == "Submit" %}
<h1> Your first name is {{firstname}}</h1>
<h1> Your last name is {{lastname}}</h1>
<h1> Your email is {{emailvalue}} </h1>
{% endif %}
</body>

I tried the below code in views.py, and it works.
from django.shortcuts import render
from django.http import HttpResponse
def index(request):
if request.method == 'POST':
student = StudentForm(request.POST, request.FILES)
if student.is_valid():
handle_uploaded_file(request.FILES['file'])
newfile = request.FILES['file'].name
firstname= student.cleaned_data.get("firstname")
lastname= student.cleaned_data.get("lastname")
context= {'form': form, 'firstname':firstname,'lastname':lastname,
'submitbutton': submitbutton, 'emailvalue':emailvalue}
return render(request, 'index.html', context)
It seems like my models.py, forms.py, urls.py and views.py are not recognizing the elements in each other and I don't understand what could be going wrong. I'm just starting the project (CS50W Project4-Network) and I noticed the problem when I tried to render the model form and the textarea field of the form linked to the model wouldn't show on the browser, it only shows when I click submit, as a missing field to be filled, I'm not sure if its because of the same pylint errors I'm getting or something else.
Here is my models:
from django.contrib.auth.models import AbstractUser
from django.db import models
class User(AbstractUser):
pass
class Post(models.Model):
body = models.TextField()
date = models.DateTimeField(auto_now_add = True)
author = models.ForeignKey(User, on_delete=models.CASCADE, related_name="author", default=None)
def __str__(self):
return f"{self.body} by {self.author} at {self.date}"
The forms.py:
from django import forms
from django.forms import ModelForm
from .models import Post
class PostForm(ModelForm):
class Meta:
model = Post
fields = ["body"]
widgets = {
"body": forms.Textarea(attrs={'class': 'form-control col-md-5 col-lg-6'}),
}
The views
from django.contrib.auth import authenticate, login, logout
from django.contrib.auth.decorators import login_required
from django.db import IntegrityError
from django.http import HttpResponse, HttpResponseRedirect
from django.shortcuts import render
from django.urls import reverse
from .forms import PostForm

**I left out logging in routes**
#login_required(login_url='login')
def create_post_page(request):
return render(request, "network/create_post.html")
def create_post(request):
posted = False
if request.method == "POST":
form = PostForm(request.POST)
if form.is_valid():
instance = form.save(commit=False)
instance.author = request.user
instance.save()
return HttpResponseRedirect("/create_post?posted=True")
else:
form = PostForm()
if "posted" in request.GET:
posted = True
return render(request, "network/create_post.html", {
"posted": posted,
"form": form
})
The urls:
from django.urls import path
from . import views
urlpatterns = [
path("", views.index, name="index"),
path("login", views.login_view, name="login"),
path("logout", views.logout_view, name="logout"),
path("register", views.register, name="register"),
path("create_post", views.create_post, name="create_post"),
path("create_post_page", views.create_post_page, name="create_post_page")
]
The template code where the form is not showing, only showing when I click submit as a missing field to be field
{% extends "network/layout.html" %}
{% block body %}
{% if posted %}
{% else %}
<h2>Create a new post</h2>
<form action="{% url 'create_post' %}" method = "POST">
{% csrf_token %}
{{ form.as_p }}
<input class="btn btn-secondary" type="submit" value="Post">
</form>
{% endif%}
{% endblock %}
The problems vscode keep raising:
No name 'Post' in module 'network.models'Pylint(E0611:no-name-in-module)
Module 'network.views' has no 'create_post' memberPylint(E1101:no-member)
Module 'network.views' has no 'create_post_page' memberPylint(E1101:no-member)
Somebody help me please, I feel like its a small problem but its driving me nuts because I can't figure out why.
Make sure you load the plugin "pylint_django" when pylint is called, and that you pass it the correct value for django-settings-module. To do this, create a file pylintrc in your project folder and give it the following contents:
[MAIN]
load-plugins = pylint_django,
django-settings-module = mysite.settings
I have a quiz. I have 2 pages, I create the questions and their answers on the first page and I put these questions on the second page, but I want these questions to have the Answer model input, i.e. each question has its own input.

When someone reaches your index page and enters the form we need to
Submit the form as a POST request to index view
Save the form thereby creating a model in the DB
Redirect the user to preview view using the above id
To do that the code needs to be somewhat like this, I have not tested it, but you should get the idea.
from django.shortcuts import redirect
def index(request):
form = RegisterForm()
if request.method == 'POST':
form = RegisterForm(request.POST, request.FILES)
if form.is_valid():
instance = form.save()
return redirect('preview', pk=instance.id)
context = {'form':form}
return render(request, 'event/index.html', context)
Inside your index.html change
action="{% url 'preview' form.id %}"
to
action=""
as we want it to post to the INDEX view as that is where out POST handling logic is.
The index view then redirects to preview using the newly generated object.
Also as mentioned by #Snir in the other answer, having .html in URLS is not a standard practice. It would be better to simple make it something like:
path('preview/<str:pk>', views.preview, name="preview")
The URL patterns are regexes, so you'll have to escape special regex characters, like the dot. Try (add r) or remove the dot:
path(r'preview.html/<str:pk>', views.preview,
name="preview")
I currently want to make a web app in django with a form that asks a user to input a phone number and submit, and I want that number they submit to be stored in a database using postgres. I'm having a hard time finding information on how to use post requests in django to connect to postgres.

How can I get this to store the phone number in the postgres db after I've initialized the project to use it? This was what I tried but I am consistently getting the error: 'ValueError at /
Cannot assign ">": "Post.user" must be a "User" instance.'
I think what I'm trying to do is quite simple, I've just never done it before with django and postgres, any help would be appreciated!
