Hello, I have an app for creating invoices, but I'd like to be able to save
a .docx of the invoice when the user creates the invoice (I'm using docx
library). I'm very new to django so any direction you can give I
appreciate. I'd like to know the proper way to go about doing this.
Right now I have it so that the 'invoice_number' is generated in the model
in the save method and the 'created_by' user is assigned to the
self.request.user in the view. Please let me know if there is a better way
to do this also. Thanks for your help!
Here is my model ...
class Invoice(models.Model):
created_at = models.DateTimeField(auto_now_add=True)
their_company = models.ForeignKey(Contact,
on_delete=models.CASCADE,blank=True, null=True,)
invoice_number = models.CharField(max_length=50, default='')
bill_to = models.CharField(max_length=255, default='')
in_trash = models.BooleanField(default=False)
created_by = models.ForeignKey(settings.AUTH_USER_MODEL)
def save(self, *args, **kwargs):
if not self.id:
today = datetime.date.today()
date_str = datetime.datetime.strftime(today, '%y%m%d')
doc_str = 'IN'
last_invoice =
Invoice.objects.filter(invoice_number__startswith=doc_str).order_by('invoice_number').last()
if last_invoice:
last_invoice_num = last_invoice.invoice_number[-2:]
new_invoice_num = int(last_invoice_num) + 1
new_invoice_num = "%02d" % new_invoice_num
else:
new_invoice_num = '01'
self.invoice_number = doc_str + date_str + new_invoice_num
super(Invoice, self).save(*args, **kwargs)
class Meta:
ordering = ['invoice_number', ]
def __str__(self):
return self.invoice_number
def get_absolute_url(self):
return reverse("accounting:invoices:detail", kwargs={"pk": self.pk})
and here is my InvoiceCreateView ...
class InvoiceCreateView(LoginRequiredMixin, CreateView):
fields = ("their_company", "bill_to")
model = Invoice
form = forms.CreateInvoiceForm()
def form_valid(self, form):
object = form.save(commit=False)
object.created_by = self.request.user
object.save()
document = Document()
#use invoice data to create invoice
#save the doc
document.save('invoice.docx')
return super(InvoiceCreateView, self).form_valid(form)
