Added queryparams to dump_data view and added test for it.

For #30

This is only the multiple app_label endpoint for the /admin/smuggler/ page. I think it makes sense to just overload the /admin/dump/ aka dump_data view to have an optional app_label feature.

Merged with some cleanup and a python 3 fix to the tests, thanks!

[pconerly]

Thanks! This is the main feature I needed-- do you have the ability to deploy to pypi? Having smuggler 0.4.2 come out this week would be great.

What features or tickets do you want to finish before publishing 0.4.2?

[semente]

I will try release this today or tomorrow. Would be great if it could be tested with Django 1.7 too.

I'm away from the office till thursday so I won't be able to do anything until then. Testing Django 1.7 is just a matter of adding it to the tox config. Hopefully everything keeps working ;). I've already updated setup.py and the readme in anticipation of a new release (0.5).

Thursday is fine. Sweet. I'm running django1.7 tox tests as we speak, PR for you momentarily.
