Add import example for force_authenticate in testing

[phalt]

Doing a bit of testing with authentication and I noticed there was no mention of where to import the force_authenticate method anywhere, so I've added it to the first example where force_authenticate is introduced.

Fixes PEP8 W503 errors

Yah.

[tomchristie]

Damnit, really need to pin pep8.

[tomchristie]

Bit meh to these silent upgrades.

We'll have to resolve it before we can merge anything else. Either pin pep8 to a lower version that's not so crazy about exactly where binary operators should be positioned, or by re-positioning 'em.

Eg:

• https://github.com/tomchristie/django-rest-framework/blob/master/rest_framework/serializers.py#L657
• https://github.com/tomchristie/django-rest-framework/blob/master/rest_framework/renderers.py#L462

Sorry - nothing related to your PR of course, but does block it.

Wow that's weird, I added a single line in the docs?

[phalt]

@tomchristie raise this as an issue / separate PR?

Testing against a newer version of pep8 than the previous commit/PR.
We pin flake8, but not pep8, which it depends on.

@phalt Yeah.

Tox is pinning pep8 to pep8==1.5.7, yet still throwing the error. Looks like tox has flake8 pinned at 2.3.0 and not 2.2.2 like in requirements.txt.

I'll just fix the pep8 errors :)

https://github.com/tomchristie/django-rest-framework/blob/master/tox.ini#L26 How can it not be running 2.2.2?

Wondering if now that we have #2568 this can be cleaned up to only include the missing import

[phalt]

@jpadilla I'll rebase and push

[phalt]

@tomchristie @jpadilla tah dah

[jpadilla]

@phalt thanks!
