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
class dInlineAdmin(admin.TabularInline):
model = d

# admin.py
@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

Comment (by kapil garg):

I think, InlineModelAdmin works for models which have related objects. In
your example,

{{{
# admin.py

class dInlineAdmin(admin.TabularInline):
model = d

@admin.register(b)

class bSpecializedAdmin(admin.ModelAdmin):
inlines = [
dInlineAdmin,
]
}}}

model "b" is not related to model "d" and thus causing the exception. The
following code will work

{{{
# admin.py
class aInlineAdmin(admin.TabularInline):
model = a

@admin.register(d)
class bSpecializedAdmin(admin.ModelAdmin):
inlines = [
aInlineAdmin,
]
}}}
