[reportlab-users] Saving the generated report into Django model

[Asif Jamadar]

I found the solution,

	def report(request)

	  response = HttpResponse(mimetype='application/pdf')
    	  response['Content-Disposition'] = 'attachment;filename=ANALYSIS_REPORT.pdf'
	  buffer = StringIO()

    	  doc = SimpleDocTemplate(buffer)
		
		#Create the PDF
	

	 doc.build(document, onLaterPages=header_footer)
    
    	 pdf = buffer.getvalue()
    
    	 myfile = ContentFile(pdf)
	
	 m = Report()
    
       m.file.save('test.pdf', myfile)
	
	 response.write(pdf) 

    	 return response

Here Report is the model and file is the field of Report model.

Hope it will help someone

How can I save the dynamically generated PDF report into separate django model (database) as file.

I created model called 'Reports', in this model I defined a FileField.

In models.py

Class Report(models.Model):

file  = models.FileField(upload_to='uploads/documents)'


In views.py

                def  report(request):

         response = HttpResponse(mimetype='application/pdf')
                         response['Content-Disposition'] = 'attachment;filename=ANALYSIS_REPORT.pdf'
                        buffer = StringIO()
                       doc = SimpleDocTemplate(response)
                       ...................................................................
                      ....................................................................
                     doc.build(document)
                     pdf = buffer.getvalue()

                   myfile = ContentFile(pdf)
                   m = Report()
                  m.file.save('test.pdf', myfile)
                  return response

But the above code saves the EMPTY report.  So any advice on how to save the generated PDF report in django model

It looks from this like you are not actually using the 'buffer' variable.  Try
    doc.build(document, filename=buffer)

Originally we allowed a filename, but later we generalised it to allow
a file-like object.
