django 1.4.2 admin

Exception Type: TypeError at /admin/article/sarticle/add/
Exception Value: 'int' object is not iterable
local vars:
name
'genre_flags'
self
<bitfield.forms.BitFieldCheckboxSelectMultiple object at 0xb40832ac>
attrs
{'id': u'id_genre_flags'}
value
0
choices
()

model:
genre_flags = BitField(flags=[
'PressRelease',
'Satire',
'Blog',
'OpEd',
'Opinion',
'UserGenerated',
], default=('PressRelease',), help_text=genres_help)

admin.py:

formfield_overrides = {
    BitField: {'widget': BitFieldCheckboxSelectMultiple},
}   

When editing the widget works as expected.
The exception occurs only when adding a new object.

fix follows

this seems to fix it. convert initial value that comes as int to a list of flag names.

dude, the formatting is not helping.

django=1.4.2
in the model:
genre_flags = BitField(verbose_name=u'Genre',flags=[
'PressRelease',
'Satire',
'Blog',
'OpEd',
'Opinion',
'UserGenerated',
], default=('PressRelease',),help_text=genres_help)
does the job for me.

Working! 👍 thanks

This works great. Can we make a pull request for this?

Here it is : #32

The usage of admin in README also has typo,

It should be,

    list_filter = (
            ('flags', BitFieldListFilter),
            )

Hi, can a maintainer merge this request. I have a similar problem. Impossible to add en entry which has a bitfield.
