OneToOneField not working with inlineadmin

[alex]

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
