Is this not a tuple?

Question

I can\'t figure out what I\'m doing wrong here. My error is: ImproperlyConfigured at /admin/ \'CategoryAdmin.fields\' must be a list or tuple.

Isn\'

Answer 1

It should be:

fields = ('title', )

Example:

In [64]: type(('title'))
Out[64]: str

In [65]: type(('title', ))
Out[65]: tuple

Answer 2

You need a comma after title:

fields = ('title',)

Answer 3

No, it is not. You need to add a comma:

fields = ('title',)

It is the comma that makes this a tuple. The parenthesis are really just optional here:

>>> ('title')
'title'
>>> 'title',
('title',)

The parenthesis are of course still a good idea, with parenthesis tuples are easier to spot visually, and the parenthesis distinguish the tuple in a function call from other parameters (foo(('title',), 'bar') is different from foo('title', 'bar')).

Answer 4

Replace it with this:

fields = ('title', )
