首先，在表单集中，用 name ="form-0-DELETE" ， name ="form-1-DELETE" 等.

First, in your formset, mark your delete checkboxes with name="form-0-DELETE", name="form-1-DELETE", etc.

然后在您的 if form.is_valid和formset.is_valid 中迭代标记为删除的值.

Then in your if form.is_valid and formset.is_valid iterate over the values marked for delete.

for delete_value in formset.deleted_objects:
    delete_value.delete()

然后继续保存表单集
