You must make sure exclude
is a tuple (or list), and not a string. If you use parenthesis with one string, the resulting value will be a string, not a tuple like you might expect:
Python 3.5.2 (default, Nov 17 2016, 17:05:23)
>>> ('foo')
'foo'
>>> ('foo', )
('foo',)
>>>
In your case, you should add a comma after 'index'
like this:
class slsummTable(tables.Table):
class Meta:
model = DailyslSumm
exclude = ('index', ) # <- note the extra comma here
