Django OperationalError no such table - django

I'm making a sign up page.
html
{{message}}
<form action="{% url 'signup' %}" method="post">
{% csrf_token %}
<div class="form-group">
<input class="form-control" autofocus type="text" name="username" placeholder="Username">

<div class="form-group">

<input class="btn btn-primary" type="submit" value="Register">
</form>
django
def signup(request):
if request.method == 'POST':
username = request.POST['username']
email = request.POST['email']
password = request.POST['password']
confirmation = request.POST['confirmation']
if password != confirmation:
return render(request, 'lms/signup.html', {
'message': 'Passwords must match.'
})
else:
try:
user = User.objects.create_user(username, email, password)
user.save()
except IntegrityError:
return render(request, 'lms/signup.html', {
'message': 'Username already taken.'
})
return HttpResponseRedirect(reverse('index'))
else:
return render(request, 'lms/signup.html')
When I submit the form, I get this error:
OperationalError at /signup
no such table: lms_user
I've already done the migrations command. I also deleted tried deleting migrations and pycache folder's content and db.sqlite3 file and did the migrations again but that didn't help either.

Django always failed when login as user, while superuser (admin) always success

So, I've tried a couple of times to register and back to login. Always failed to log in except for superuser or admin. Already checked in Django admin that the user that I have registered already there.
There is no error message in the terminal when login or register a user. Except for the error message that I've created in views.py if log in unsuccessful.
So, let's take a look into my code. First views.py
from django.contrib.auth import authenticate, login, logout
def login_view(request):
if request.method == "POST":
# Attempt to sign user in
username = request.POST["username"]
password = request.POST["password"]
user = authenticate(request, username=username, password=password)
# Check if authenticate successful
if user is not None:
login(request, user)
return HttpResponseRedirect(reverse("index"))
else:
context = {
"message": "Invalid username and/or password"
}
return render(request, "page/login.html", context)
else:
return render(request, "page/login.html")
def register(request):
if request.method == "POST":
username = request.POST["username"]
email = request.POST["email"]
# Ensure password matches with password confirmation
password = request.POST["password"]
confirmation = request.POST["confirmation"]
if password != confirmation:
context = {
"message": "Both password must match"
}
return render(request, "page/register.html", context)
# Attempt to create new user
try:
user = User.objects.create_user(username)
user.save()
except IntegrityError:
context = {
"message": "Username already exist"
}
return render(request, "page/register.html", context)
login(request, user)
return HttpResponseRedirect(reverse("index"))
else:
return render(request, "page/register.html")
And below is the template both for log in and register.
<!-- Logintemplate -->
<div class="login-register">
<div class="head">
Log in to Explore
</div>
<form action="{% url 'login' %}" method="post">

<div class="form-floating mb-3">

{% if message %}

{% endif %}
</div>

Is there something I missed or action that I need to perform?
You create the user as follows:
user = User.objects.create_user(username)
This creates a user without a password which means your user would not be able to login. pass the username and password both to the create_user method:
user = User.objects.create_user(username=username, password=password)
Note: Use a form class to make forms in Django to perform validation and cleaning. For making a user use the
UserCreationForm

updating an user's object in django

I have a problem with updating an existing user object in my database. When I update and change the user object it saves and everything is looking ok but when I change the user and I want to login this user does not authenticate. Here is my code:
def profile_edit(request):
user = request.user
profile = request.user.profile
context = {
'user': user
}
if request.method == 'POST':
username = request.POST.get('username')
password = request.POST.get('password')
email = request.POST.get('email')
user.profile.address = request.POST.get('address')
user.profile.phone = request.POST.get('phone')
user.set_password('password')
user.username = username
user.save()
user.profile.save()
authenticate(user)
context = {
'profile': profile
}
return render(request, 'helpdesk/profile.html', context)
return render(request, 'helpdesk/profile_edit.html', context)
and login view:
def login_view(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)
profile = request.user.profile
context = {
'profile': profile
}
return render(request, 'helpdesk/user_desk.html', context)
else:
context = {
'username': username,
'error': 'user not find!'
}
else:
context = {}
return render(request, 'helpdesk/login.html', context)
When updating the password you are actually setting the string 'password' as password and not the submitted password. Change user.set_password('password') to user.set_password(password) to correct this.

if password and confirm and password != confirm:
newUser = (User.objects.create_user(username,email,password))
newUser.save()
login(request,newUser)
return render(request,"login.html")
return render(request,"login.html")
so how can i solve this problem?

Signup page redirecting to same page without printing any error

After POST method signup page always redirects to same page without printing any message or redirecting to homepage or login page but I am tracing it in every steps by printing something to check how it is working. But I can signup a new user using python shell.
Terminal is giving me only this:
[28/Nov/2019 15:36:26] "GET / HTTP/1.1" 200 2574
[28/Nov/2019 15:36:46] "POST / HTTP/1.1" 200 2574

if form.is_valid():
user = form.save(commit= False)
username= form.cleaned_data['username']
password= form.cleaned_data['password']
user.set_password(password)
user.save()
authenticate(username= username, password= password)
Profile.objects.create(
user= user,
full_name=form.cleaned_data['full_name'],
codeforces_id= form.cleaned_data['codeforces_id'],
Uva_Id = form.cleaned_data['Uva_Id'],
points = 0,
department= form.cleaned_data['department']
)
if user is not None:
if user.is_active:
login(request,user)
return redirect('/')
return render(request, 'signup.html',{'msg':'Invalid'})

CSRF verification failed. Request aborted. Unusual case

I suppose that the problem of this error is hidden in template. Here is my form:
<form class="form-horizontal loginFrm" action="/login/" method="post">
{% csrf_token %}
<div class="control-group">
<input type="text" id="inputEmail" placeholder="Email" name = "username">
</div>
<div class="control-group">
<input type="password" id="inputPassword" placeholder="Password" name = "password">
</div>
<div class="control-group">
<label class="checkbox">
<input type="checkbox"> Remember me
</label>
</div>
<input type="submit" class="btn btn-success" value="Sign in">
</form>
<button class="btn" data-dismiss="modal" aria-hidden="true">Close</button>
And my login view:
def login(request):
args = {}
args.update(csrf(request))
if request.POST:
username = request.POST['username']
password = request.POST['password']
user = auth.authenticate(username=username, password=password)
if user is not None:
auth.login(request, user)
args['username'] = username
return HttpResponseRedirect('/', args, context_instance=RequestContext(request))
else:
return HttpResponseRedirect('/', args, context_instance=RequestContext(request))
else:
return HttpResponseRedirect('/',args,context_instance=RequestContext(request))
In my last project, it worked correctly. But here is this error.
View the html source on your page with the rendered login form and confirm that you have a hidden field with the csrf token.
Something like this:
<input type='hidden' name='csrfmiddlewaretoken' value='NzYXoXbN9beogdB6gf22rNXkTNQd6Jri' />
It's possible that the view you have is not passing the context_instance. It depends which method you are using to render the view in the first place.
You could use:
return render_to_response('my_template.html',
context_instance=RequestContext(request))
Or the easier render() which will automatically use RequestContext
return render(request, 'my_template.html')
as a case you can use ensure_csrf_cookie view decorator.
