Question

我正在关注Need a minimal Django file upload example

随着每次上传，列表越来越多，如何通过python shell手动删除对象数据，即文档：文档对象

>>> 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，同时确保调用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.
