【问题描述】：

这是我的 Django 视图：

    def get_initial_queryset(self):
    filter_dict=

    location=self.request.POST.get('location_id')
    if location:
        set_if_not_none(filter_dict, 'port__device__host__location', location)
    client=self.request.POST.get('client')   
    if client:
        set_if_not_none(filter_dict, 'client__icontains', client)
    phone=self.request.POST.get('phone')    
    if phone:
        set_if_not_none(filter_dict, 'phone__icontains', phone)
    if line:
        set_if_not_none(filter_dict, 'line__icontains', phone)

    return Client.objects.filter(**filter_dict)

这里我需要用where phone like %phone% or line like %phone%这样的OR条件进行过滤 如何使用过滤器做到这一点？

【参考方案1】：

见Complex queries with Q objects。你需要这样写：

from django.db.models import Q
Client.objects.filter(Q(phone__icontains=phone) | Q(line__icontains=phone))

你也可以像这样构建 Q 对象：

filter = Q()
location = self.request.POST.get('location_id')
if location:
    filter = filter & Q(port__device__host__location=location)
client = self.request.POST.get('client')
if client:
    filter = filter & Q(client__icontains=client)
phone = self.request.POST.get('phone')
if phone:
    filter = filter & (Q(phone__icontains=phone) | Q(line__icontains=phone))
return Client.objects.filter(filter)
