If I'm understanding you correctly, you could use a callable in the
list_display definition.
https://docs.djangoproject.com/en/2.0/ref/contrib/admin/#django.contrib.admin.ModelAdmin.list_display
def lower_case_name(obj):
return ("%s" % str(obj).lower()
lower_case_name.short_description = 'Substance'
class SubstanceAdmin(admin.ModelAdmin):
list_display = (lower_case_name,)

Subject: Admin case-insensitive sorting question
I have tried every which way to produce a case-insenstive list of substances in
the Admin including this:
def get_queryset(self, request):
return super(SubstanceAdmin,
self).get_queryset(request).order_by(Lower('name').asc())
Which DOES work (as proven via print statement) but doesn't display that way in
the Admin which uses the natural ascii order. It is the list_display feature
which re-orders the substances.
I can get them sorting pseudo-insensitively by using a method to uppercase the
first char of the name and passing that method to list_display.
However, that prevents the column order reversal feature which is a function of
the list_display feature.
I thought a case insensitive model manager might work until I saw in the docs
that subsequent order_by filtering will spoil it and I would still have to
pseudo_name them anyway.
So the question is ... should I bite the bullet and add a sort field to the
model and fill it with the substance name converted to lower-case?
Thanks
Mike
