Using pure HTML forms in Django views - html

Question

SO I'm tryng to create a Django site using HTML forms.The form takes in vendor choice and amount, which is then needed to be passed into views. The employee table's balance needs to be updated, with the amount paid deducted from the balance of the current logged in user, and an entry needs to be added to the transaction table stating the details, with credit = 0, rest info taken from form. How can this be done?
Given below are my files:
html:
<form method="POST" action="/profiles/updatingBalance">
<div class="custom-control custom-radio">
<input type="radio" class="custom-control-input" value="1" id="defaultUnchecked" name="defaultRadios">
<label class="custom-control-label" for="defaultUnchecked">Vendor 1</label>
</div>
<div class="custom-control custom-radio">
<input type="radio" class="custom-control-input" value="2" id="defaultUnchecked" name="defaultRadios">
<label class="custom-control-label" for="defaultUnchecked">Vendor 2</label>
</div>
<input type="" class="form-control" id="amount1" name="amt" aria-describedby="emailHelp" placeholder="Enter amount">
<br>
<button type="submit" class="btn btn-primary">Submit</button>
</form>
Models.py:
from django.db import models
from django.contrib.auth.models import User
import django
import datetime
# Create your models here.
class vendor(models.Model):
id = models.CharField(max_length=20, on_delete=models.CASCADE, primary_key=True)
name = models.CharField(maxlength=30, on_delete=models.CASCADE)
class employee(models.Model):
name = models.OneToOneField(User, on_delete=models.CASCADE)
id = models.CharField(max_length=20, on_delete=models.CASCADE, primary_key=True)
balance = models.IntegerField(default=0)
class transaction(models.Model):
vendor_id = models.ForeignKey(vendor, on_delete=models.CASCADE)
emp_id = models.ForeignKey(employee, on_delete=models.CASCADE)
debit = models.IntegerField()
credit = models.IntegerField()
timestamp = models.DateField(_("Date"), default=datetime.date.today)
Here's the views.py I tried. I got till updating emplyee table's balance(not sure if it's correct):
def updatingBalance(request):
if request.method=="POST":
ven_id = request.POST["defaultRadios"]
amount = request.POST["amt"]
x = employee.objects.filter(id = request.User.id)
x.balance = x.balance - amount
p = transaction(vendor_id =ven_id.value, emp_id = request.User.id, debit=amount, credit=0)
p.save()
return render(request, 'profiles/userLogin.html', employee)
return HttpResponseRedirect(request.META.get('profiles/userLogin.html'))
I am confused as to how data can be taken from pure html forms( I'm a beginner), and how that info can be used to get my desired results. Any help would be greatly appreciated.

Answer 1

to get the data from form you should pass the view that will process the information in the action attribute of the form, then with request.POST dictionary you can extract the data that you want.
html:
<form method="POST" action="/Yourapp/theview/">
your html
</form>
views:
def theview(request):
amount=request.POST["amt"]
