django - 如何删除对象数据

Question

我正在关注需要一个最小的 Django 文件上传示例

每次上传时，列表都在增加，我如何删除对象数据，即Document: Document object通过 python shell 手动

>>> from myproject.myapp.models import Document

>>> Document.objects.all()

[<Document: Document object>, <Document: Document object>, <Document: Document object>, <Document: Document object>, <Document: Document object>, 

>>> Document

  <class 'myproject.myapp.models.Document'>

Answer 1

删除所有对象：-

Document.objects.all().delete()

删除满足某些过滤器的对象：-

Document.objects.filter(<your_filters>).delete()

删除对象但也要确保调用 django 信号（如果有）：

for document in Document.objects.filter(<your_filters>):
    document.delete()

Answer 2

remove(obj1, obj2, ...)
    Removes the specified model objects from the related object set.
