Question

在Django,你们如何想获得两种不同的价值观,就像以下那样?

profile_setting = (pSetting.objects.get(module="my_mod", setting_value=1) or
                   pSetting.objects.get(module="my_mod", setting_value=0))

Answer 1

http://docs.djangoproject.com/en/dev/topics/db/queries/#complex-lookups-with-q-objects”rel=“noreferer”



profile_setting = pSetting.objects.get(Q(module="my_mod"),
                  Q(setting_value=1)|Q(setting_value=0))

此外,为了改进你的编码风格,请大家看一下编码准则。 PSetting。

Answer 2

你们是否确信你只是一个物体?

如果你试图 gr一堆物体,那么你们都需要做的是链条过滤器:

profile_setting = pSetting.objects.filter(module="my_mod", setting_value__in=0)
                         .filter(module="my_mod", setting_value__in=1)

然而,由于除了确定价值之外的一切都一样,你只能看一看一个清单或图:

profile_setting = pSetting.objects.filter(module="my_mod", setting_value__in=[0,1])

(如果你确信你只拿一个物体作为对你的询问的答复,上述建议是罚款)

Answer 3

这项任务的标的有<代码>Q(>>) : 标的

例如:

profile_setting = pSetting.objects.get(
    Q(module="my_mod", setting_value=1) | Q(module="my_mod", setting_value=0)
)

Answer 4

 profile_setting = pSetting.objects.get(module="my_mod",setting_value__in=[0,1])

Answer 5

对于这类询问,请查阅以下文件:

and for your specific problem you can pass multiple queryset objects(Q) for queryset use | for OR condition and & for AND condition in both get() and filter() functions.
