Django高级过滤 [英] Django Advanced Filtering

问题描述

可以根据模型字段的选择过滤查询集吗？

Can I filter a queryset based on a model field's choices?

模型：

COLORS = (
    ('BLACK', 'black'),
    ('RED', 'red'),
    ('BLUE', 'blue'),
    //etc..
)

class Thing(Models.model):
    color = models.CharField(max_length=5, choices=COLORS)

查看：

def filter_by_color(request):
    q = Thing.objects.filter(???) 

有没有办法根据不同的颜色选择过滤 Thing ？另外，有没有办法动态写入，所以所有的颜色选择都可以响应单个视图？

Is there a way to filter Thing based on different color choices? Also, is there a way to write this dynamically, so that all color choices can respond to a single view?

推荐答案

想要这个？

查看

def filter_by_color(request, color):
     q = Thing.objects.filter(color=color)

所以当你访问 http：// yoursite / thisview / black 您将获得 Thing s黑色，当您访问 http：// yoursite / thisview / red 你会得到 Thing s，用红色。

So when you access http://yoursite/thisview/black you will get Things with black color and when you access http://yoursite/thisview/red you will get Things with red color .
