format_suffix_patterns causes error in viewsets and routers tutorial

[patrickchiuco]

Hello!

I've been following the viewsets and routers tutorial and ran into this issue:

This has been my code so far. The only solutions I've found was to remove format_suffix_patterns and am currently finding other solutions so that I can still use suffix patterns in the url.

I've also tried using routers instead of registering them straight, and ran into the same problem:

The following is the code I have so far:

Again the only solution I've found was to turn off format_suffix_patterns by doing so:
router.include_format_suffixes = False

Any help would be greatly appreciated! Thank you.

Already saw the problem. format_suffix_pattern was being called twice and I didn't comment out my last call. Please ignore this discussion and close it.
