Firstly thanks for this awesome project :) and for Cheat Sheets ;)

Here is my problem:
I tried to create circuit with a pretty long name:
TL2-902011-1.RU.ANT.5A-RU.MSK.M9A​
And got an error:
"Server Error
There was a problem with your request. This error has been logged and administrative staff have been notified. Please return to the home page and try again."

Circuit was created, but if I tried to enter it or delete it I get the same error.

I can not find where is netbox logs located, so I can not provide more info on this error.
But it is reproducible.

Well, this is strange. The problem isn't the length, but rather that there's some invisible junk hanging off the end of that string. I copied and pasted the circuit name you provided:

>>> name="TL2-902011-1.RU.ANT.5A-RU.MSK.M9A​"
>>> name
'TL2-902011-1.RU.ANT.5A-RU.MSK.M9A\xe2\x80\x8b'

This causes an issue in the circuit's __unicode__ method. I don't know how to prevent this from happening, but if you delete and recreate the circuit with a clean string it should be fine.

I just realized this circuit can't be deleted even through the admin UI because it tries to evaluate __unicode__ on the confirmation page and yields the same error.

To delete it, hover over the link to it in the circuits list and make a note of its numeric primary key. Then, run ./netbox/manage.py shell and paste in the following:

from circuits.models import Circuit
Circuit.objects.get(pk=<PK>).delete()

Thanks, I can delete it from shell.
It seems there is a problem with the last symbol if I insert string then delete last symbol and retype it Circuit created without a problem.
In shell is also good:

>>> name = 'TL2-902011-1.RU.ANT.5A-RU.MSK.M9A'
>>> name
'TL2-902011-1.RU.ANT.5A-RU.MSK.M9A'

So the problem was in messed string.
Thank you for help!
