小编rma*_*oft的帖子

我有以下型号:

class Process(models.Model):
  title = models.Charfield(max_length=255)
  date_up = models.DateTimeField(auto_now_add=True)
  days_activation = models.PositiveSmallIntegerField(default=0)

现在我需要Process根据它们的值来查询已过期的所有对象days_activation.

我试过了

from datetime import datetime, timedelta

Process.objects.filter(date_up__lte=datetime.now()-timedelta(days=F('days_activation')))

并收到以下错误消息:

TypeError:timedelta days组件的不支持类型:F

我当然可以用Python做到这一点:

filter (lambda x: x.date_up<=datetime.now() - timedelta(days=x.days_activation), 
        Process.objects.all ()), 

但我真的需要制作一个django.db.models.query.QuerySet.

当我执行时,我需要安装ruby-debug-base19以便在Netbeans IDE上激活调试:

$ gem install ruby-debug-base19

我收到以下错误.从日志生成中提取

巧合的是,我运行pip search django命令,我有时间错误.甚至指定高值超时

在日志下面:

以下脚本的目的是同时执行许多功能,但我不知道为什么它不能正常工作.
这些功能以顺序方式执行,而不是并行执行.

我很感激任何建议澄清我,我做错了什么.
