" Area Tecnici" formset,只有内联实例,但其中一些是空的。如何避免显示空头?我只想内联一个modelAdmin内联实例,如果它有一些实例
(例如" SL Formazioni"和#34; HACCP"有一些例子,但" SL Valutazioni"" Prestazioni& Servizi" don& #39; t,所以我不想内联" SL Valutazioni"和#34; Prestazioni& Servizi")

您应该覆盖ModelAdmin.get_formsets_with_inlines
。
class MyModelAdmin(admin.ModelAdmin):
inlines = [MyInline, SomeOtherInline]
def get_formsets_with_inlines(self, request, obj=None):
for inline in self.get_inline_instances(request, obj):
# FILTER THE INLINE FORMSET TO YIELD HERE
# For example, given obj.related_instances value
if obj is not None and obj.related_instances.count() > 0:
yield inline.get_formset(request, obj), inline
