I am trying to use a html form from the internet with Django. However, after watching crazy amount of videos on youtube and reading through https://docs.djangoproject.com/en/1.10/topics/forms/ , I can't manage to make it work. When I click the submit button, Chrome tells me the "The form has submitted", but nothing else happens. It should log the user in and redirects to the index page.
registration_form.html

I am new to Django and I was trying to select a foreign key from my html template and save it in my database. It worked fine in admin panel but when I created a template myself I could display all the keys but I got error while posting the form.
Here is the model, views and html code.
# urls.py
from django.contrib import admin
from django.urls import path
from Home import views
urlpatterns = [
path('', views.home, name="Home"),
path('postBlog', views.postBlog, name="Post-Blog"),

# from Home.forms import BlogForm
# Create your views here.
def home(request):
return render(request, 'Home/HomePage.html')
def postBlog(request):
if request.method == 'POST':
title = request.POST.get('title')
author = request.POST.get('author')
blog = request.POST.get('blog')
date = request.POST.get('date')
time = request.POST.get('time')
form = Blog(title=title, author=author, body=blog, date=date, time=time)
form.save()
return render(request, 'Home/HomePage.html', {'dic': form})
else:
users = User.objects.all()
dic = {'users': users}
return render(request, 'Forms/Post-Blogs.html', dic)
# models.py

I got this error: Cannot assign "'2'": "Blog.author" must be a "User" instance.
When trying to create a simple web page with login and sign up i ran into the issue of django not recognzing the created user. In views.py i created a simple message that displays "Incorrect password or email" if user does not exist. I created a user and made sure that the password was correct when i inputed it into the login form however it still gave me the message of "Incorrect password or email". Instead of redirecting to home like a created user should it errored and i could not figure out why it is not accepting the password/email in the form.
views.py
from django.shortcuts import redirect, render
from django.contrib.auth import authenticate, login, logout
from django.contrib import messages
from django.contrib.auth.models import User
def home(request):
return render(request, 'home.html')
def signup(request):
if request.method == "POST":
email = request.POST['email']
password = request.POST['password']
myuser = User(email=email)
myuser.set_password(password)
myuser.save()
messages.success(request, "Your account has been successfully created ")
return redirect('signin')
return render(request, 'signup.html')
def signin(request):
if request.method == "POST":
email = request.POST['email']
password = request.POST['password']
user = authenticate(request, email = email, password = password)
if user is not None:
login(request, user)
email = user.email
messages.success(request, "Successfully Logged In")
return redirect ('home')
else:
messages.info(request, "Email or Password is Incorrect")
return render(request, 'signin.html')
return render(request, 'signin.html')

What is the status of your user. An inactive user is one that has its is_active field set to False. The default backend ModelBackend and RemoteUserBackend prohibits the inactive users from authenticating. You didn't specify user status. So please check the user status also.
You can improve this part as following:
myuser = User(email=email, is_active=True)
myuser.set_password(password)
myuser.save()
To set password you have to use set_password function.
I've created a login page as a homepage and only by adding manually in Django administration can create a user. I didn't create a registration form and message error else statement in home viwes.py is working on the admin panel. If I login by user, I get CSRF token error
homepage

<a href="{% url 'signup' %}">

</div>
</form>
for creating user you must use
User.objects.create_user() method
Ex: User.objects.create_user(username=username,email=email,password=password)
I can't render form username on the template. like I want to to render the form fields automatically which I defined in forms.py file but it's not working. here you go below for my detailed files
forms.py
class CreateUserForm(UserCreationForm):
class Meta:
model = User
fields = ['username', 'email', 'password1', 'password2']

form = CreateUserForm(request.POST)
if form.is_valid():
form.save()

def regPage(request):
form = CreateUserForm()
if request.method == 'POST':

if form.is_valid():
form.save()
# consider adding a redirect page here this is a good approach
else:
context = {'form':form}
return render(request, 'web/car-finder-home.html',context) # your forgot to add context
Now inside your template you can access the form...
I didn't add in core urls.py
from my_app_name import urls
urlpatterns = [
path('cars/', views.regPage, name="register"),
]
xD
I am unable to save my form responses to the database as an object in Django.
Everytime I click on submit to submit my form, I am just logged out of my website and the object isnt saved in the database either.
Can anyone tell me where I am going wrong?
This is my models in models.py.
class Chain(models.Model):
name = models.CharField(max_length=255)
user = models.ForeignKey(User, on_delete=models.CASCADE)
year = models.CharField(max_length=10, default="20XX")
sem = models.CharField(max_length=30, default="Default Semester")
code = models.CharField(max_length=10, default="SUB-CODE")
slot = models.CharField(max_length=10, default="EX+EX")
last_updated = models.DateTimeField(auto_now=True)
def __str__(self):
return self.name
This is my view in views.py file.
#login_required(login_url='/')
def create_course(request):
if request.method == 'GET':
return render(request, 'create_course.html', {})
elif request.method == 'POST':
name=request.POST['name']
year=request.POST['year']
sem=request.POST['sem']
code=request.POST['code']
slot=request.POST['slot']
newchain = Chain(
name=name,
year=year,
sem=sem,
code=code,
slot=slot,
)
newchain.user = request.user
newchain.save()
return redirect('success')
This is my HTML code for the form.
{% extends 'authmain.html' %}
{% block content %}
<h3> <p class="text-center"> Create a new Course Blockchain: </p> </h3>
<div class="card border-dark mb-3 mx-auto" align="center" style="width: 40rem;">
<div class="card-body">
<h5 class="card-title">
<form method='POST'>
{% csrf_token %}
<label for="year">Year: </label>
<input type="text" id="year" name="year" value=""><br>
<label for="code">Course Code: </label>
<input type="text" id="code" name="code" value=""><br>
<label for="name">Course Name: </label>
<input type="text" id="name" name="name" value=""><br>
<label for="slot">Slot: </label>
<input type="text" id="slot" name="slot" value=""><br>
<label for="sem">Semester: </label>
<input type="text" id="sem" name="sem" value=""><br>
<button class="btn btn-outline-primary" type="Submit"> Create </button>
</form>
</h5>
</div>
</div>
{% endblock %}
This is my urls.py.
from django.urls import path, include
from . import views
urlpatterns = [
path('', views.home, name="home"),
path('register/', views.register, name="register"),
path('logout/', views.logoutuser, name="logoutuser"),
path('dashboard/', views.dashboard, name="dashboard"),
path('create_course/', views.create_course, name="create_course"),
path('success', views.success, name="success"),
]
This is the view function for success.
#login_required(login_url='/')
def success(request):
return render(request, 'success.html', {})
The issue is that you are not closing form tag in the authmain.html.
<ul class="navbar-nav ml-auto">
<li class="nav-item">
<form action="{% url 'logoutuser' %}" method='POST'>
{% csrf_token %}
<button class="btn btn-outline-info mb-auto" type="submit">Logout</button>
----- CLOSING FORM TAG MISSING HERE ---
</li>
</ul>
and when you submit the form at Create Course, you actually trigger this form, which logs out the user. Add closing tag to the logout form and you'll fix your problem.
Sometimes debugging can be a bit tricky.
To save directly in the database in Django use Model.objects.create()
Chain.objects.create(user=request.user, name=name, year=year, sem=sem,
code=code, slot = slot)
You need to use a model form to achieve this
class MyForm(ModelForm):
class Meta:
model = MyModel
fields = []
And then you can do something like this:
form = MyForm(request.POST)
if form.is_valid():
new_item = form.save()
...
And it will save directly to the database.
