How to convert large object to xml file?

Question

Django

In a project I'm using
data = render_to_string("****.xml", products)
The product object got too big and the process is being killed at runtime.
How to deal with it?

Answer 1

1. Use queryset.iterator() to get rid of storing the whole list of objects
   
2. Use StreamingHTTPResponse to not buffer all output
   
3. Form XML not entirely using a cycle in the template, but one element at a time (plus XML header / footer)
