combine modelformset and inlineformset in django views

[Asif Jamadar]

I have two models

   class A(models.Model):
name = models.CharField(50)
type = models.CharField(50)

   class B(models.Model):
field1 = ForeignKeyField(A)
value = IntegerField()

I need to generate both formsets and inline formsets using the above models.

For class A I will generate model formset, but i'm not getting how to bind 
inline formset for model B to modelformsets

How can I combine both modelformsets from model A and inline formsets  from 
model A and model B on save method in django views?

How to read barcoded value from PDF

[Asif Jamadar]

Hi,


 I have a PDF document which consist of barcode characters. Now how can I 
retrieve that bar-coded value programmatically. When I googled I found a tool 
called Pypdf which provides a function called 'PdfFileReader'

To read the PDF file, but how can I read the barcode form the existing PDF. Any 
solution?





In Reportlab I can do the following code to generate barcode and to get the 
value of that barcode



barcode=code39.Extended39("123456789",barWidth=0.2*mm,barHeight=8*mm)



bc = Paragraph("Barcode value: %s" % barcode.value, STYLES['Normal'])



document.append(bc)

But how can I achieve this from the existing PDF document??
