Request.POST or Request.POST.get both not providing values in views.py
Question
I am not using Forms in my solution and only trying to get the values from the request.POST so as to save it in the database in the Views.py.
It was working before but strangely when I print the key, value pair of the request object it sometimes shows the value and sometime has None in it.
HTML:

Views.py - I will eventually try to get all the form fields but for the sake of debugging I am trying to get one form field only.
def modify(request, customer_customerid):
customer = get_object_or_404(Customer, pk=customer_customerid)
if request.method =='POST':
customer.CustomerShortName = request.POST.get('txtCustShortName','')
customer.save()
return redirect('/customers/' + str(customer_customerid))
Model.py
class Customer(models.Model):
customerid = models.AutoField(db_column='CustomerID', primary_key=True) # Field name made lowercase.
customername = models.CharField(db_column='CustomerName', max_length=50) # Field name made lowercase.
customershortname = models.CharField(db_column='CustomerShortName', max_length=50) # Field name made lowercase.
msastartdate = models.DateField(db_column='MSAStartDate') # Field name made lowercase.
msaenddate = models.DateField(db_column='MSAEndDate') # Field name made lowercase.
externalcustomer = models.BooleanField(db_column='ExternalCustomer') # Field name made lowercase.
state = models.CharField(db_column='State', max_length=50) # Field name made lowercase.
country = models.CharField(db_column='Country', max_length=50) # Field name made lowercase.
alldatasourcerequired = models.BooleanField(db_column='AllDataSourceRequired') # Field name made lowercase.
timezone = models.CharField(db_column='TimeZone', max_length=50) # Field name made lowercase.
lastmodifiedutc = models.DateTimeField(db_column='LastModifiedUTC') # Field name made lowercase.
lastmodifiedby = models.CharField(db_column='LastModifiedBy', max_length=50) # Field name made lowercase.
active = models.BooleanField(db_column='Active') # Field name made lowercase.
class Meta:
managed = False
db_table = 'Customer'
Updated with the View which renders the form:
def detail(request, customer_customerid):
customer = get_object_or_404(Customer, pk=customer_customerid)
contact = Contact.objects.get(reftable='Customer',
refid=customer_customerid)
country = Country.objects.all()
location = LocationTimezoneMapping.objects.all()
context = {'customer':customer,'contact':contact, 'country': country, 'location':location}
return render(request, 'customers/detail.html', context)

I needed to update the URL in the html form by appending the URL with "modify" so that there is a difference in the landing URL and the URL after clicking the Save button.
This is necessary as the my view and edit pages were on the same html.
jquery in html
$("#btnSave").click(function(){
$(location).attr("href").append("modify")
$("#frmDetails").submit();
});
URL.py
path('modify/<int:customer_customerid>/', views.modify, name='modify'),
