myuser = User.objects.create_user(username, email, pass1)
myuser.first_name = fname

the error line which it is highlighting:
return redirect(request, "/home.html")

You specified path("", views.home, name="home") in your urls.py, therefore you can just do:
return redirect("/")
You shouldn't be passing request as a first argument to redirect(), you only need to provide a URL (relative or absolute) most of the time.
Actually, as a best practice, that URL should be provided using reverse, e.g.:
from django.urls import reverse
...
return redirect(reverse('home'))
See the doc for redirect().

Custom url based off single html input without JS

So I have probably the simplest task you could ever wish for with an html form that I cannot solve.
I want to input a brand name into a search bar, click submit and it redirect to the url/brand/[input]
I already have a working view for the urls setup in django. How would I structure the form to actually create my desired url?
<form method="GET" action="">
<input type="text" name="brand" id="brand" placeholder="Search..." aria-label="Search">
<button type="submit">Search</button>
</form>
views.py
class GetByBrand(ListView):
def get(self, request, brand):
urls.py
urlpatterns = [
path('', GetListView.as_view(), name='home'),
path('brands/<str:brand>/', GetByBrand.as_view())
]

<form method="GET" action="brands/">
<input type="text" name="brand" id="brand" placeholder="Search..." aria-label="Search">
<button type="submit">Search</button>
in URLs(import views by from. import views)
urlpatterns = [
path('brands/', views.GetByBrand),
]
in Views
from django.http import HttpResponse
def GetByBrand(request):
s = request.GET['brand']
return HttpResponse(s)

OR use AJAX in Javascript in your HTML file
$('#brand').on('submit',function(e){
var brand = $('input[name=brands]')
$.get("brands/"+brand, function(data, status){
alert("Data: " + data + "\nStatus: " + status);
});
})

So I basically solved this by using the code I had previously tried which is identical to what Wagas Develper recommended. What I had not done though was add this last line to the urls.py in the main project folder. (and I'm still not sure why this solved it but found the solution from throwing crap at the wall)
urlpatterns = [
path('admin/', admin.site.urls),
path('', include('shoes.urls')),
path('brands/', include('shoes.urls'))
For anyone curious about how the class based view is structured now.
class GetByBrand(ListView):
def get(self, request, brand):
get_results = request.GET.get('q')
The urls.py in the same directory as views.py (within app dir not main project dir)
urlpatterns = [
path('', GetListView.as_view(), name='home'),
path('brands/<str:brand>/', GetByBrand.as_view()),
path('brand_results/', GetByBrand.as_view(), name='b')
]
HTML Form
<form method="GET" class="form-inline my-2 my-lg-0" action="{% url 'b' %}">
<input class="form-control mr-sm-2 search-btn" type="text" name="q" value="{{request.GET.q}}" placeholder="Search..." aria-label="Search">
<button class="btn btn-outline-success my-2 my-sm-0" type="submit">Search</button>
</form>

no matter whether the verification code I input is wrong or right, the error is always The view users.views.RegisterView didn't return an HttpResponse object. It returned None instead.

Django's view should return some response.
From doc:
A view function, or view for short, is simply a Python function that takes a Web request and returns a Web response. This response can be the HTML contents of a Web page, or a redirect, or a 404 error, or an XML document, or an image . . . or anything, really.
So you need to add return statement to post() method, e.g. like this:
def post(self,request):
...
return render(request, 'register.html',{'register_form':register_form})

Django form not rendering properly

I am following the documentation of the Django Forms but I do not know why my form does not want to show up !
I am creating a form that will get an email en create invitation for user to sign in using this app :https://github.com/bee-keeper/django-invitations
My forms.py:
class InviteForm(forms.Form):
email1 = forms.EmailField(label='Email 1')
My Views.py:
from django.shortcuts import render
from django.views.generic import TemplateView
from .forms import InviteForm
class candidateIndex(TemplateView):
template_name= 'candidateIndex.html'
class HRIndex(TemplateView):
template_name= 'HRindex.html'
def create_invite(request):
if request.method == 'POST':
form = InviteForm(request.POST)
if form.is_valid:
email = form.cleaned_data['email1']
invite = Invitation.create('form.email1')
invite.send_invitation(request)
print("The mail was went")
else:
print("Your form is not valid")
else:
form = InviteForm()
return render(request, 'HRindex.html', {'form': form})
My HTML:
{% extends 'base.html' %}
{% block body %}
<div class="jumbotron">
<h1>Welcome to SoftScores.com</h1>
<h2>Team analytics platfom</h2>
<h3>Welcome to {{user.username}}, it is your Page</h3>
</div>
<div class="container">
<p>
<a class="btn btn-primary" data-toggle="collapse" href="#collapseExample" aria-expanded="false" aria-controls="collapseExample">
Create a new team
</a>
</p>
<div class="collapse" id="collapseExample">
<div class="card card-body">
In order to create a new team please invite new members. A link will be sent to them in order to give the access to the application
</div>
<form method="post">
{% csrf_token %}
{{ form.as_p }}
<input type="submit" value="Submit" />
</form>
</div>
</div>
urls.py:
from django.conf.urls import url
from website import views
app_name = 'website'
urlpatterns = [
url(r'^candidateIndex/$', views.candidateIndex.as_view(), name='candidate_index'),
url(r'^HRIndex/$', views.HRIndex.as_view(), name='HR_index'),
]
When it render the page I get only the button but the form does not seems to work
Do you habe any idea ?

You HR_index url is being handled by the HRIndex view, but this does not have any code to handle the form.
url(r'^HRIndex/$', views.HRIndex.as_view(), name='HR_index'),
Since a TemplateView is not really suited to handling a form, it would be better to modify the URL pattern to use the create_invite view instead:
url(r'^HRIndex/$', views.create_invite, name='HR_index'),

how to use Django redirect to the original request after login

I practice how to use django login , but it can't redirect to the page before login
Please teach me how to do it Thank you very much
My project name is :proj
And I have an app name: app1
when I go to http://127.0.0.1:8000/f/index/ it will redirect to http://127.0.0.1:8000/accounts/login/?next=/f/index/
and after I enter the username and password,
I want to redirect to http://127.0.0.1:8000/f/index/ ( by the parameter ?next=/f/index/) but don't know how to do .
app1/views.py :
from django.contrib.auth.decorators import login_required
#login_required
def index(request):
logger.info('test')
....
proj/urls.py:
urlpatterns = patterns('',
url(r'^accounts/login/$', 'proj.views.login'),
url(r'^accounts/logout/$', 'proj.views.logout'),
url(r'^accounts/auth/$', 'proj.views.auth_view'),
proj/views.py
from django.shortcuts import render_to_response
from django.http import HttpResponseRedirect
from django.contrib import auth
from django.core.context_processors import csrf
def login(request):
c={}
c.update(csrf(request))
return render_to_response('proj/login.html',c)
def auth_view(request):
username = request.POST.get('username','')
password = request.POST.get('password','')
user = auth.authenticate(username=username,password=password)
if user is not None:
auth.login(request,user)
# return HttpResponseRedirect(request.POST.get('next')) #not work
else:
return HttpResponseRedirect('/accounts/invalid')
proj/login.html:
{% if form.errors %}
<p class="error">Sorry.that's not valid </p>
{% endif %}
<form action="/accounts/auth/?next={{ request.get_full_path|urlencode }}" method="post">{% csrf_token %}
<label for="username" >User name:</label>
<input type="text" name="username" value="" id="username">
<label for="password" >Password:</label>
<input type="password" name="password" value="" id="password">
<input type="submit" value="login" />
</form>

try this in views.py:
if user is not None:
auth.login(request,user)
return HttpResponseRedirect('/f/index/')

when you type url, and you are not login before, and django redirect to the url :http://127.0.0.1:8000/accounts/login/?next=/f/index/
after entering your username and password, and click submit button, django redirect you automatically to http://127.0.0.1:8000/f/index/
using URLresolver.
