Hi,
May I get help with this project? I am new to Django. Below is my view and
model for your review.
class Invoice(models.Model):
InvoiceNo = ShortUUIDField(length=16,
prefix="GN_",
alphabet="1234567890",
primary_key=True,
)
InvoiceDate = models.DateField(default=datetime.now, blank=True)
Account = models.CharField(max_length=50, blank=True)
PaymentDueDate = models.DateField(default=datetime.now, blank=True)
Location = models.ForeignKey(Location, on_delete=models.DO_NOTHING,
blank=True, default=1)
# Product = models.ForeignKey(Product, on_delete=models.DO_NOTHING)
Test = models.ManyToManyField("Products", blank=True,
related_name="products")
Address = models.ForeignKey(Address, on_delete=models.DO_NOTHING)
#Quantity = models.IntegerField(blank=True, default=1)
Tax = models.IntegerField(default =0)
SubTotal = models.DecimalField(blank=True,
null=True,decimal_places=2,max_digits=10)
Total = models.DecimalField(blank=True,
null=True,decimal_places=2,max_digits=10)
#Ful = models.FloatField(blank=True)
def save(self, *args, **kwargs):
#rate = Product.objects.get(pk=self.Product.id
<http://self.product.id/>)
test = Products.objects.all()
total = 0
for my in test:
total += my.SubTotal
self.SubTotal = total
self.Total = self.SubTotal + self.Tax
#self.Total = Sum(self.Total) + Sum( self.SubTotal)
super(Invoice, self).save(*args, **kwargs)
# @property
# def PerformSub(self):
# myval = self.Quantity * self.Product.Price
# return myval
# @property
# def PerformCal(self):
# self.Total = self.SubTotal + self.Tax
# def __str__(self):
# return self.InvoiceNo
class Products(models.Model):
ProductDate = models.DateField(default=datetime.now, blank=True)
Title = models.CharField(max_length=50, blank=True)
Description = models.CharField(max_length=150, blank=True)
Sku = models.CharField(max_length=50, blank=True)
Price = models.FloatField(blank=True)

SubTotal = models.DecimalField(blank=True,
null=True,decimal_places=2,max_digits=10)
SalesPrice = models.CharField(max_length=50, blank=True)
def save(self, *args, **kwargs):
# rate = Products.objects.get(pk=self.Product.id
<http://self.product.id/>)
self.SubTotal = self.Price * self.Quantity
super(Products, self).save(*args, **kwargs)
def __str__(self):
return self.Title + "" + self.Description
class InvoiceForm(ModelForm):
class Meta:
model = Invoice
fields = ['InvoiceNo', 'InvoiceDate', 'Account','PaymentDueDate',
'Location','Test', 'Address', 'Tax', 'SubTotal', 'Total'
]
Here is my view. Any help will be much appreciated thank you .
def dashboard(request):
# forms = admin.get_form(invoices, res)
location = Location.objects.all()
address = Address.objects.all()
products = Products.objects.all()
form = InvoiceForm()
# invoice = Invoice.objects.all()
# invoice = get_object_or_404(Invoice)
if request.method == 'POST':
form = InvoiceForm(request.POST)
if form.is_valid():
# myinvoice = form.save(commit=False)
print("test")
invoiceTest = form.save(commit=True)
invoice = Invoice()
invoice.InvoiceNo = form.cleaned_data['InvoiceNo']
invoice.InvoiceDate = form.cleaned_data['InvoiceDate']
invoice.Account = form.cleaned_data['Account']
invoice.PaymentDueDate = form.cleaned_data['PaymentDueDate']
invoice.Location = form.cleaned_data['Location']
invoice.Test = form.cleaned_data['Test']
invoice.Tax = form.cleaned_data['Tax']
invoice.SubTotal = form.cleaned_data['SubTotal']
invoice.Total = form.cleaned_data['Total']
invoiceTest.save()
# invoice.save_m2m()
# print(invoiceForm)
# invoice =
Invoice(InvoiceNo=InvoiceNo,InvoiceDate=InvoiceDate,Account=Account,PaymentDueDate=PaymentDueDate,Location=mylocation,Tax=Tax,SubTotal=SubTotal,Total=Total)
# invoice.save()
return HttpResponseRedirect('index')
else:
form = InvoiceForm()
# return redirect('dashboard')
return render(request, 'pages/dashboard.html', { "form" :form ,
'Location': location, 'Address': address, 'Products': products})
