This class hierarchy doesn't work with inlineadmin:
class hierarchy:
models.py:
{{{
class d:
pass
class a:
d = models.OneToOneField(d, on_delete=models.CASCADE,
related_name="host")
class b:
pass
}}}
admin.py
{{{
class dInlineAdmin(admin.TabularInline):
model = d
@admin.register(b)
class bSpecializedAdmin(admin.ModelAdmin):
inlines = [
dInlineAdmin,
]
}}}
Error message:
`<class 'x.admin.RequirementInlineAdmin'>: (admin.E202) 'x.Requirement'
has no field named 'host'.`
'host' is the related_name
