在我的情况下，更改表单加载非常慢在管理界面中，因为 models.py 中的 SeverHasDisk 模型中的one_to_one字段“disk”。 admin.py 中的 ServerHasDiskInLine 中有磁盘字段。当我从admin.py中的 ServerHasDiskInLine 中排除“磁盘”字段时，它可以正常工作。 有没有办法通过 ServerHasDiskInLine（admin.TabularInline）使用表单类来提高性能 或其他什么？

答案 0 :(得分：0)
这是快速解决方案。 我刚刚在 Admin.py 中为 ServerHasDiskInLine 类添加了一个属性 raw_id_fields =（“disk”，）所以新类是
class ServerHasDiskInline(admin.TabularInline):
model = ServerHasDisk
raw_id_fields = ("disk",)
extra = 0
classes = ('grp-collapse grp-open',)
#exclude = ['disk']
