Python 3 incompatibility: inventory page table empty with puppetboard 0.2.1

[buzzdeee]

Hi,

accessing /inventory, I see the header of the inventory table, with all its columns, but the table contents is not rendered. Running the daemon in debug mode I see following backtrace:

[2017-02-13 13:21:24 +0100] [11148] [DEBUG] GET /inventory

I just have this in my default_settings.py with regard to INVENTORY_FACTS:

INVENTORY_FACTS = [('Hostname', 'fqdn'),
('IP Address', 'ipaddress'),
('OS', 'lsbdistdescription'),
('Architecture', 'hardwaremodel'),
('Kernel Version', 'kernelrelease'),
('PuppetXXX Version', 'puppetversion'), ]

Just added these XXX to see if it takes it and they are shown in the web interface.
Downgrading again to puppetboard 0.2.0 makes it work again.

I found this thread:
http://stackoverflow.com/questions/30418481/error-dict-object-has-no-attribute-iteritems-when-trying-to-use-networkx
so changed iteritems -> items and the table contents is rendered properly.

0.2.0 as well as the 0.2.1 run with python 3.6.0

@buzzdeee The support of Puppetboard is still limited to Python < 3 as mentioned in the header of the README:

At the current time of writing, Puppetboard supports the following Python versions:

    Python 2.6
    Python 2.7

[buzzdeee]

I was wading through the README, but obviously missed that.
Anyways, for the OpenBSD port, where I run it on, I patched that little thing,
and updated it just yesterday to the 0.2.1, since everything else seems to run fine with python 3.
So, I don't mind if you keep the issue open as a reminder, or close it with that it doesn't apply.
Looking forward to some official python 3 support ;)

@buzzdeee We are moving to python 3x support, so thanks for the feedback.

[nikolaik]

Seeing the same after bumping to 0.2.2 just now. Looking forward to a 0.3.0 release including #355 :-)

[mterzo]

This should work now that 0.3.0 is released.

[jvperrin]

I can confirm this appears to be fixed with the release of 0.3.0 and Python 3 (3.5 in our case).

[larsnaesbye]

Can't we close this issue since it has been confirmed to have been fixed in 0.3.0?
