New description:
loaddata.py incorrectly throws an ImproperlyConfigured exception when
FIXTURE_DIRS is a list of one. See:
https://github.com/django/django/blame/798835112d81b852efaae0e067af389c733cd1b3/django/core/management/commands/loaddata.py#L296
I changed this code to:
{{{
286 print(fixture_dirs)
287 print(len(fixture_dirs))
288 print(len(set(fixture_dirs)))
289 if len(fixture_dirs) != len(set(fixture_dirs)):
290 raise ImproperlyConfigured("settings.FIXTURE_DIRS contains
duplicates.")
}}}
and set my FIXTURE_DIRS like so:
`FIXTURE_DIRS=('piece/core/fixtures','piece/core/fixtures2')`
when I run loaddata I see:
{{{
('piece/core/fixtures', 'piece/core/fixtures2')
2
2
Installed 6 object(s) from 2 fixture(s)
}}}
so far so good. Now set it like so:
`FIXTURE_DIRS=('piece/core/fixtures'')`
I run it and get:
{{{{
piece/core/fixtures
19
12

Comment:
`FIXTURE_DIRS=('piece/core/fixtures')` is not a list or tuple it's a
string that contains duplicates e.g. `'e'`.
