You forgot the case for normal GET request :)
something like that
def register(request):
form = UserRegisterForm()

form = UserRegisterForm(request.POST)
if form.is_valid():
form.save()
return redirect('login')
return render(request, 'register.html', {'form': form})

View didn't return HTTPResponse object

I was trying to create a blog app by following an online Django tutorial and while I was testing the sign-up page, I ran into a Value Error saying that the view did not return a HTTP response object. i tried everything but i could not find the answer as i am not a Django expert
in the users app's views.py file was the code that threw the error
from django.shortcuts import render, redirect
from django.contrib.auth.forms import UserCreationForm
from django.contrib import messages
def register(request):
if request.method == 'POST':
form = UserCreationForm(request.POST)
if form.is_valid():
username = form.cleaned_data.get('username')
messages.success(request, f'Account Created for {username}')
return redirect('blog-home')
else:
form = UserCreationForm()
return render(request, 'users/register.html', {'form': form})
and this is the register template
{% extends "myblog/base.html" %}
{% block content %}
<div class="content-section">
<form method="POST">
{% csrf_token %}
<fieldset class="form-group">
<legend class="border-bottom mb-4">
Join Today!
</legend>
{{ form.as_p }}
</fieldset>
<div class="form-group">
<button class="btn btn-outline-info" type="submit">
Sign Up!
</button>
</div>
</form>
<div class="border-top pt-3">
<small class="text-muted">
Already Have an account?
Sign In!
</small>
</div>
</div>
{% endblock content%}
And this is the file structure of the project
File Structure
If we have a POST request, and the form is not valid, you do not return anything. Unindent the render call, so:
def register(request):
if request.method == 'POST':
form = UserCreationForm(request.POST, request.FILES)
if form.is_valid():
username = form.cleaned_data.get('username')
messages.success(request, f'Account Created for {username}')
return redirect('blog-home')
else:
form = UserCreationForm()
return render(request, 'users/register.html', {'form': form})
You can write function like this ...
def register(request):
form = UserCreationForm()
if request.method == 'POST':
form = UserCreationForm(request.POST)
if form.is_valid():
username = form.cleaned_data.get('username')
messages.success(request, f'Account Created for {username}')
return redirect('blog-home')
else:
form.errors
context = {'form': form}
return render(request, 'users/register.html', context)
return something for the function register also , you are returning only in if else conditions
return render(request, 'users/register.html', {'form': form}) add this at the end of the function outiside if else (now we have returned something for the function register also , you are returning only in if else conditions

How to stop Django from rendering result in new tab

I have following views and each time form is submitted, result is rendered in new tab which has empty form.
How to render result in same form (with data submitted) without opening new tab?
views.py
class contact(View):
def __init__(self, logger=None, **kwargs):
self.logger = logging.getLogger(__name__)
def get(self, request):
return render(request, 'test.html')
def post(self, request):
if request.method == 'POST':
form = ContactForm(request.POST, request.FILES)
if form.is_valid():
self.host = form.data['ip']
messages.success(request, "Successful")
else:
form = ContactForm()
else:
form = ContactForm()
return render(request, 'test.html', {'form':form})
forms.py
class ContactForm(forms.Form):
ip = forms.CharField()
urls.py
urlpatterns = [
path('', contact.as_view()),
]
html
<body>
<form action="/" method= "post" enctype="multipart/form-data">
{% csrf_token %}
{{ form }}
<button type="submit">Submit</button>
</form>
</body>
if form.is_valid()
form.save()
messages.success(request, 'Contact request submitted successfully.')
return render(request, 'your_page.html', {'form': ContactForm(request.GET)})

Cant uploading data through foreign key with crispy forms

I am uploading a photo by using a foreign key in forms but I didn't get any data in a database and I didn't get any errors.
models.py
from django.db import models
class username(models.Model):
name=models.CharField(max_length=100)
phone=models.BigIntegerField()
email=models.EmailField(max_length=100)
class Profilephoto(models.Model):
profile_photo = models.FileField(upload_to='media/')
uname = models.ForeignKey(username, on_delete=models.CASCADE, null=True)
forms.py
from django import forms
from .models import Profilephoto
class DocumentForm(forms.ModelForm):
class Meta:
model = Profilephoto
fields = ['profile_photo','uname']
view.py
from django.shortcuts import render, redirect, HttpResponse
from .models import username,Profilephoto
from .form import DocumentForm
def home(request):
if request.method == 'POST':
name = request.POST['name']
phone = request.POST['phone']
email = request.POST['email']
username(name=name,phone=phone,email=email).save()
users = username.objects.latest('id')
return render(request, 'home.html',{'usernames': users})
else:
users = username.objects.latest('id')
return render(request, 'home.html',{'usernames': users})
def data1(request,id):
if request.method == 'GET':
obj = username.objects.get(id=id)
form = DocumentForm(instance=obj)
return render(request, 'data1.html', {'form': form, 'usernames': obj})
elif request.method == 'POST':
obj = username.objects.get(id=id)
form = DocumentForm(request.POST, request.FILES, instance=obj)
if form.is_valid():
form.save()
return redirect('home')
return render(request, 'data1.html', {'usernames': obj})
data1.html
<form method="post" enctype="multipart/form-data">
{% csrf_token %}
{{ form|crispy }}
<div align="center">p
<button type="submit" class="btn btn-primary">Submit</button>
</div>
</form>
Please Help me Thanks in Advance
It's happening because your DocumentForm is form of model Profilephoto and in view function you are passing Username's instance.
so in your views.py, try this:
def data1(request,id):
if request.method == 'GET':
obj = username.objects.get(id=id)
form = DocumentForm()
return render(request, 'data1.html', {'form': form, 'usernames': obj})
elif request.method == 'POST':
obj = username.objects.get(id=id)
form = DocumentForm(request.POST, request.FILES)
if form.is_valid():
form.save()
return redirect('home')
return render(request, 'data1.html', {'usernames': obj})

Django forms - submitting the data isn't working

I'm really new to Django and I want to teach myself my making a simple note. But I don't understand how django forms work. I made simple template when I can display the user's notes and now I am trying to make a view when the user can add new notes to account using a simple form.
Here is my views.py file
from django.shortcuts import render, redirect
from django.contrib.auth.forms import UserCreationForm
from django.contrib.auth.models import User
from django.contrib.auth import authenticate, login, logout
from .forms import CreateUserForm, CreateNoteForm
from django.contrib import messages
from django.contrib.auth.decorators import login_required
from .models import *
# Create your views here.
def loginPage(request):
if request.method == 'POST':
username = request.POST.get('username')
password = request.POST.get('password')
user = authenticate(request, username=username, password=password)
if user is not None:
login(request, user)
return redirect('home')
else:
messages.info(request, 'Username or pasword is incorrect')
context = {}
return render(request, 'accounts/login.html', context)
def registerPage(request):
form = CreateUserForm()
if request.method == 'POST':
form = CreateUserForm(request.POST)
if form.is_valid():
form.save()
user = form.cleaned_data.get('username')
messages.success(request, 'Account was created for '+ user)
return redirect('home')
context = {'form': form}
return render(request, 'accounts/register.html', context)
def logoutUser(request):
logout(request)
return redirect('login')
#login_required(login_url='login')
def home(request):
if request.user.is_authenticated:
username = request.POST.get('username')
context = {'username': username}
return render(request, 'accounts/home.html', context)
def notes(request):
username = None
if request.user.is_authenticated:
username = request.user.username
user_id = request.user.pk
user_notes = Note.objects.filter(user=user_id)
context = {
'user_notes': user_notes,
'username': username,
#'user_id' : user_id,
}
return render(request, 'accounts/notes.html', context)
def createNote(request):
username = request.user.username
user_id = request.user.pk
user_notes = Note.objects.filter(user=user_id)
form = CreateNoteForm()
if request.method == 'POST':
form = CreateNoteForm(request.POST)
if form.is_valid():
form.save()
return redirect('notes')
context = {'user_notes': user_notes, 'form': form}
return render(request, 'accounts/create_note.html', context)
forms.py:
from django.forms import ModelForm
from django import forms
from django.contrib.auth.forms import UserCreationForm
from django.contrib.auth.models import User
from .models import Note
class CreateUserForm(UserCreationForm):
class Meta:
model = User
fields = ['username', 'email', 'password1', 'password2']
class CreateNoteForm(forms.ModelForm):
class Meta:
model = Note
fields = ['user', 'title', 'text']
and create_note.html:
{% extends 'accounts/main.html' %}
{% load static %}
{% block content %}
<br>
<br>
<div class="container">
<div class="card text-white bg-dark mb-3">
<div class="container">
<form action="{% url 'notes' %}" method="POST">
<div class="card-body">
{% csrf_token %}
{{form}}
<input type="Submit" name="Submit">
</div>
</form>
</div>
</div>
</div>
{% endblock %}
The problem is the new note isn't added when I submit the data. And also if anyone have other suggestions for structuring my views or making this app better I am happy to read them and learn new ways of improving my project. Sorry for long post. I am really noob.
