創建一個動態查詢

Question

請告訴我如何使這個查詢動態：

products = category.product_set.filter(Q(feature__value__value='Red') 
|Q(feature__value__value='Blue'), feature__name__name='Color') 

我需要顯示所有的顏色紅色和藍色的產品。

並請告訴我如何更好地做到這一點查詢：

產品全部用紅色和藍色，但與選項-1。我的理解是正確的？：

products = category.product_set.filter(Q(feature__value__value='Red') 
|Q(feature__value__value='Blue'), feature__name__name='Color').filter(Q(feature__value__value='Yes') 
|Q(feature__value__value='No', feature__name__name='Option-1') 

Answer 1

我想你要找的東西是這樣的：

# create a dynamic set of keywords 
kwargs = {} 
name = 'Color' 
# since you're looking for literals, I would simply use 'in' as the query 
kwargs[name + "__in"] = ['Red','Blue'] 

products = category.product_set.filter(**kwargs)
