Can you explain what ur problem briefly.
In the Admin I show a list of substance names and against each one there
can be a list of clickable links to public chemical databases. When the
user clicks one of those links the database opens in a new browser page
with that substance showing. The user may then browse that public
database for info on that substance.
Currently we have hard-coded three of 14 or 15 different public chemical
databases. Different users have different preferences so I want to allow
them to select their preferred one or two in their company profile and
tweak the Admin to check the profile and display those instead of the
hard-coded three.
Since sending that earlier email I have adjust the field type to
ListField (import CharField as ListField) so that I know there is only
one field in the entire project which is a ListField. This is for CSS
and formfield_overrides.

In the Admin I would like to provide the user with checkboxes
against a list of options not stored in the database.
Specifically, I want to retrieve a comma separated list of
integers from a model field choices attribute. The model field
looks like this:
menu_links = models.CharField(max_length=LARGE, blank=True,
choices=MENU_LINKS, default='',
validators=[int_list_validator], verbose_name='Menu data
links', help_text="These selections control which URLs are
displayed in the " "'Substances and mixtures' menu", )
I'm seeing two problems.
One is getting such a widget to appear in an admin.StackedInline
class.
Two is creating the data in the above models.CharField from
choices=MENU_LINKS
Here it is ...
MENU_LINKS = [ (1, "ChemIDplus"), (2, "ChemSpider"),
(3, "NIST Webbook"), ]
In the admin I have tried
class
ProfileFilteredSelectMultiple(admin.widgets.FilteredSelectMultiple):
def __init__(self, verbose_name='Menu links',
is_stacked=False, *args, **kwargs): args +=
(verbose_name,) args += (is_stacked,)
super(ProfileFilteredSelectMultiple, self).__init__(*args, **kwargs)
Then in the nested StackedInline class ...
class CompanyProfileInline(admin.StackedInline):
model = CompanyProfile formfield_overrides = {
CharField: {'widget': ProfileFilteredSelectMultiple},
} readonly_fields = (('modified', 'modified_by',))
fieldsets = ( ('More detail for company
profile', { 'classes': ('collapse', 'wider'),
'fields': ( 'menu_links',
...
Any hints or pointers will be appreciated.
Thanks
Mike
