Eg: def view1 ( request ): val1, val2, val3 = do_common_stuff ( request ) # non-common stuff here return render ( request, "templatename", vars ) def view2 ( request ): val1, val2, val3 = do_common_stuff ( request ) # non common stuff here return render ( request, "templatename2", vars ) def do_common_stuff ( request ): # all your common code here return computed_val1, val2, val3 In other words, unless you really know what you're doing, once you return the HttpResponse object, that should be the last thing you do. Note, though. that if your "common code" wants to WRITE INTO the HttpResponse object, thats fine too... just create one and then pass it as a parameter to your common function. -- You received this message because you are subscribed to the Google Groups "Django users" group.

Then what is the fun of making the function, if it is not reusable.

What will i do if i have a large number of views having the common part.

Thanks, for the kind advise.

Re: calling the view function in the other view function
It's generally very messy for one "view" function to call another.
Better solution is to factorise out the common parts into a third function,
then make sure each of your two "view" functions have the required
render_to_response.
Also, I highly recommend using the "render" shortcut, which would turn your
more complex calls into this:
return render ( request, 'report/report_base.html', {'Head':Head,} )
