Backwards compatibility
I wrote this post in 2010, more than 13 years ago.
It may be very out of date, partially or totally incorrect. I may even no longer agree
with this, or might approach things differently if I wrote this post today. I rarely edit
posts after writing them, but if I have there'll be a note at the bottom about what
I changed and why. If something in this post is actively harmful or dangerous please get in
touch and I'll fix it.
Backwards compatibility is pain sometimes:
# We need backwards compatibility with code which spells it this way:
# def my_view(): pass
# my_view = cache_page(my_view, 123)
# and this way:
# my_view = cache_page(123)(my_view)
# and this:
# my_view = cache_page(my_view, 123, key_prefix="foo")
# and this:
# my_view = cache_page(123, key_prefix="foo")(my_view)
# and possibly this way (?):
# my_view = cache_page(123, my_view)
