Question

基于我选择的多个过滤器，我在JSON下面创建了。

{
    "category1": ["A", "B", "C"],
    "category2": ["x", "y", "z"],
    "category3": ["med1", "med2"]
}

我正在寻找从JSON以上动态创建的以下查询

query=((Q(category__name__contains="category1") &
(Q(subcategory__name__contains="A")|  
Q(subcategory__name__contains="B")|Q(subcategory__name__contains="C"))
)|(Q(category__name__contains="category2") &
(Q(subcategory__name__contains="x")| 
Q(subcategory__name__contains="y")|Q(subcategory__name__contains="z"))

)|(Q(category__name__contains="categor3") & 
(Q(subcategory__name__contains="med1")| 
Q(subcategory__name__contains="med2"))
))

Product.objects.filter（查询）

关于如何做到这一点的任何想法？我是否必须使用行SQL查询或者可以通过Django查询来完成？

Answer 1

用于：

query = (Q(category__name__contains="category1") &
         Q(subcategory__name__in=json['category1'])) |
        (Q(category__name__contains="category2") &
         Q(subcategory__name__in=json['category2'])) |
        (Q(category__name__contains="categor3") & 
         Q(subcategory__name__in=json['categor3']))

为AND＆amp;创建动态查询使用django的OR条件
