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
