如何使用字符串作为关键字参数？

本文介绍了如何使用字符串作为关键字参数？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 具体来说，我试图使用一个字符串仲裁过滤ORM。我已经尝试过exec和eval解决方案，但是我正在进入墙壁。下面的代码不起作用，但这是我知道如何解释我想去哪里的最好方法。

from gblocks.models import Image f ='image__endswith =jpg'＃将在另一个区域脚本化，但以文本< user input> d = Image.objects.filter（f） ＃对于非django pythonistas：d = Image.objects.filter（image__endswith =jpg） ＃将是非动态的等价物。

解决方案

d = Image.objects.filter（** {'image__endswith'：jpg}）

Specifically, I'm trying to use a string to arbitrairly filter the ORM. I've tried exec and eval solutions, but I'm running into walls. The code below doesn't work, but it's the best way I know how to explain where I'm trying to go

from gblocks.models import Image f = 'image__endswith="jpg"' # Would be scripted in another area, but passed as text <user input> d = Image.objects.filter(f) #for the non-django pythonistas: d = Image.objects.filter(image__endswith="jpg") # would be the non-dynamic equivalent.

解决方案

d = Image.objects.filter(**{'image__endswith': "jpg"})
