I am new to Django Class Based Views and I am working on a project where on the template I want to have Form for creating customer accounts on the left and list of existing customers on the right. So far I have the list of existing customers displayed but for the form I don't know how to pass its variable context to the same template, or it is not possible to Pass a Form that would be submitted inside a ListView Method. And I also want to generate unique account numbers of 10 Digits in ModelForm which I want the form field to be auto-filled and disabled Here is my form code:
import secrets
#I want to Generate Account Number of 10 Digits but getting only 2
account = secrets.randbits(7)
#class for Customer Account Form
class CustomerAccountForm(forms.ModelForm):
def __init__(self, *args, **kwargs):
super().init(*args, **kwargs)
self.fields['accountnumber'].initial = account
class Meta:
model = Customer
fields = ['accountnumber','surname','othernames','address','phone']
Code for my views (ListView)
class CustomerListView(ListView):
model = Customer
form_class = CustomerAccountForm
template_name = 'dashboard/customers.html'
#Function to get context data from queries
def get_context_data(self, **kwargs):
context_data = super().get_context_data(**kwargs)
#Get Day of today from current date and time
now = datetime.datetime.now()
#Get the date today
date_today = datetime.datetime.now().date
#Count Number of Withdrawals Today and passing in context
context_data['count_withdrawals_today'] = Witdrawal.objects.filter(date__year=now.year, date__month=now.month, date__day=now.day).count()
context_data['count_deposits_today'] = Deposit.objects.filter(date__year=now.year, date__month=now.month, date__day=now.day).count()
context_data['count_accounts'] = Customer.objects.count()
context_data['count_users'] = User.objects.count()
#Calculate today Deposit Today
context_data['total_deposit']= Deposit.objects.filter(date__year=now.year, date__month=now.month, date__day=now.day).aggregate(total_deposit=Sum('deposit_amount')).get('total_deposit') or 0
#Calculate today Withdrawal Today
context_data['total_withdrawal']= Witdrawal.objects.filter(date__year=now.year, date__month=now.month, date__day=now.day).aggregate(total_withdrawal=Sum('withdrawal_amount')).get('total_withdrawal') or 0
return context_data
Someone should please help me on how this is properly done and the form would be submitted successfully. Thanks in anticipation for your answer.

secrets.randbits(k)
generates a random integer within a bit range.
For k=4 then Unsigned integer From 0 to 15.
For k=8 then Unsigned integer From 0 to 255.
For k=16 then Unsigned integer From 0 to 65,535, and so on.
If you want 10 random digits then you can use for example:
import random
account = "".join(str(random.randint(0, 9)) for _ in range(10))

After going through many tutorials and blogs on Django Class Based Views with ListViews for Forms, I discovered that ListViews was designed to populate Model items while FormViews is designed for creating and processing forms both can't be used on one template. In these case, I concluded that for a Django Template to be able to process Model Form and at the same time Populate Database items, it needs not to use Class Based Views but Function Based Views.
