管理者リストビューに外部キー「会社名」を表示しようとしています。ただし、リストビューには、会社の(なし)のみが表示されます。私は何を間違っているのですか?
admin.py
class CampaignAdmin(admin.ModelAdmin):
#fields = ['name', 'Company_name', 'active', 'modified', 'created']
list_display = ['name', 'related_company', 'active', 'modified', 'created']
list_filter = ['active']
search_fields = ['name']
sortable_field_name = "name"
autocomplete_lookup_fields = {
'name': ['name'],
}
def related_company(self, obj):
return '%s'%(obj.Company.name)
related_company.short_description = 'Company'
admin.site.register(Campaign, CampaignAdmin)
