使用AND

Question

我有一个django查询来过滤模型并打印出符合搜索条件。

以下是观点

if user_search != '' and (start_date != '' and end_date != ''):
    items = Order.objects.filter(
         Q(client__email__iexact=user_search) , Q(created_on__range=(start_date, end_date))
        )
    print "items ", items

django过滤器用于打印用户搜索的电子邮件地址，该地址属于日期范围。 但是代码我还打印了一些未经搜索但仍在日期范围内的电子邮件

这是模型

class Order(models.Model):
    client               =      models.ForeignKey(User, related_name = "order_user")
    order_number         =      models.CharField(max_length = 12)null=True)
    terms_and_conditions =      models.BooleanField(default=False)
    order_status         =      models.CharField(max_length = 20, choices = ORDER_STATUS, default = "new")
    created_on           =      models.DateTimeField(auto_now_add = True)
    edited_on            =      models.DateTimeField(auto_now_add = False)



    def __unicode__(self):
        return self.order_number

使用&对Q个对象执行AND操作。

if user_search != '' and (start_date != '' and end_date != ''):
    items = Order.objects.filter(
         Q(client__email__iexact=user_search) & Q(created_on__range=(start_date, end_date))
        )
    print "items ", items
