Creating new user with random password in django - django

Question

I have been working on a project where admin registers users to use the website. say in my case admin registers teachers and students of the school. I need some way to create random password for every new user and a email will be sent using registered email with the password. I am using custom user model.
class MyAccountManager(BaseUserManager):
def create_user(self, email, username, password=None):
if not email:
raise ValueError("Users must have email Id")
if not username:
raise ValueError("Users must have an username")
user = self.model(email=self.normalize_email(email),
username=username)
user.set_password(password)
user.save(using=self._db)
return user
def create_superuser(self, email, username, password=None):
user = self.create_user(email=self.normalize_email(email),
username=username,
password=password)
user.role = 'ADM'
user.is_admin = True
user.is_staff = True
user.is_superuser = True
user.save(using=self._db)
return user
class User(AbstractUser):
email = models.EmailField(verbose_name="Email", unique=True)
ROLE_CHOICES = [
('STD', 'STUDENT'),
('THR', 'TEACHER'),
('ADM', 'ADMIN')
]
role = models.CharField(max_length=3, choices=ROLE_CHOICES, default='STD')
username = models.CharField(max_length=50, unique=True)
first_name = models.CharField(max_length=30)
last_name = models.CharField(max_length=30)
date_of_birth = models.DateField(null=True)
description = models.TextField(null=True)
image = models.ImageField(default='default.jpg', upload_to='profile_pics')
date_joined = models.DateTimeField(verbose_name="date joined", auto_now_add=True)
last_login = models.DateTimeField(verbose_name="last login", auto_now=True)
is_admin = models.BooleanField(default=False)
is_staff = models.BooleanField(default=False)
is_superuser = models.BooleanField(default=False)
USERNAME_FIELD = 'username'
REQUIRED_FIELDS = ['email']
objects = MyAccountManager()
here my register view.
#login_required
def register(request):
if not request.user.is_superuser:
return HttpResponse('Unauthorized', status=401)
if request.method == 'POST':
form = UserRegisterForm(request.POST)
if form.is_valid():
username = form.cleaned_data.get('username')
email = form.cleaned_data.get('email')
password = User.objects.make_random_password(length=10,
allowed_chars='abcdefghjkmnpqrstuvwxyzABCDEFGHJKLMNPQRSTUVWXYZ23456789')
form.save()
user = User.objects.filter(username=username)
user.set_password(password)
user.save()
send_mail(
'Login details',
'Here is your login details \n username : ' + username + '\n password : ' + password,
from_email=None,
recipient_list=[email],
fail_silently=False,
)
messages.success(message="Email has been sent to " + email + ".")
return redirect('register')
else:
form = UserRegisterForm()
return render(request, 'users/register.html', {'form': form})
here is my UserRegisterForm
class UserRegisterForm(UserCreationForm):
email = forms.EmailField(required=True)
def __init__(self, *args, **kwargs):
super(UserCreationForm, self).__init__(*args, **kwargs)
del self.fields['password1']
del self.fields['password2']
class Meta:
model = User
fields = ['username', 'email', 'role']
What are the possible ways I can set this. I tried by overriding form.save() by didnt seem to work.

Form .save() accepts an optional commit keyword argument, if you call save() with commit=False, then it will return an object that hasn’t yet been saved to the database. You can modify the data and then save it.
def register(request):
...
f = UserRegisterForm(request.POST)
if f.is_valid():
u = f.save(commit=False)
raw_password = User.objects.make_random_password(...)
u.set_password(raw_password)
u.save()
...
Template
<form action="..." method="post">
{% csrf_token %}
{{ form }}
<input type="password" name="password1" value="random_value" hidden>
<input type="password" name="password2" value="random_value" hidden>
<input type="submit" value="Submit">
</form>
