Django: Formset saved data retrieved single raw - django

Question

I am using Inlineformsets for an app. Data gets saved but when I retrieve data, main form data is correctly retrieved however in case of childmodel, only first raw is retrieved from DB.
Views.py
#login_required
def invoice_detail(request,pk):
invoice_detailmain = serviceinvoice.objects.get(pk=pk)
if invoice_detailmain.user != request.user:
raise PermissionDenied
invoiceitems =invoice_detailmain.serviceitems1.filter(pk=pk,user=request.user)
return render(request,'account/invoicedetail.html',{'invoice_detailmain':invoice_detailmain,
'invoiceitems':invoiceitems})
template.html
{% for items in invoiceitems %}
<tr><td>{{ items.Product }}</td>
<td>{{ items.UOM }}</td>
<td>{{ items.Quantity }}</td>
<td>{{ items.Rate }}</td>
<td>{{ items.Tax_rate }}</td></tr>
{% endfor %}
models.py
class serviceinvoice(models.Model):
user=models.ForeignKey(settings.AUTH_USER_MODEL,related_name='invoice')
invoice_number=models.PositiveIntegerField()
#invoice_no = models.CharField(max_length = 500, default = increment_invoice_number, null = True, blank = True)
invoice_date = models.DateField()
invoice_receivable=models.ForeignKey(Receivables,null=True)
total_amount=models.DecimalField(decimal_places=2,max_digits=20)
total_amountwithtax=models.DecimalField(decimal_places=2,max_digits=20)
company_det=models.ForeignKey(Company,related_name='companydetails')
class Meta:
unique_together = (("user", "invoice_number"),)
ordering=('-invoice_number',)
def __str__(self):
return self.invoice_number
def get_absolute_url(self):
return reverse('invoice:editinvoice', args=[self.invoice_number])
class serviceinvoiceitems(models.Model):
user=models.ForeignKey(settings.AUTH_USER_MODEL,related_name='serviceinvoiceitems')
invoice_number=models.ForeignKey(serviceinvoice,related_name='serviceitems1')
Product=models.CharField(max_length=1000,null=True)
UOM=models.CharField(max_length=100,null=True)
Quantity=models.FloatField(null=True)
Rate=models.FloatField(null=True)
Tax_rate=models.FloatField(null=True)
def __str__(self):
return self.invoice_number

Answer 1

I believe that your filtering is incorrect. Instead of
invoiceitems = invoice_detailmain.serviceitems1.filter(pk=pk,user=request.user)
you should be using
invoiceitems = invoice_detailmain.serviceitems1.filter(user=request.user)
Although I'm baffled to why you have a primary key from both serviceinvoice and serviceinvoiceitems to your user model. It would probably be enough for you to specify
invoiceitems = invoice_detailmain.serviceitems1.all()
