如何使用多个关键字在django中查询数据库

我有一个Job模型，有这样的类

class Job(models.Model):
 title = models.CharField(max_length=100)

我想查询jobs_job数据库以实现搜索功能

def search(request):
 if request.method == "GET":
   search_terms = request.GET['title']
   search_terms = search_terms.split(',')

   jobs = Job.objects.filter(title__contains=search_terms[0])

问题是我只能将一个项目传递给contains方法，

如何使用多个单词搜索作业模型标题属性

Answer 1

例如你可以做

from django.db.models import Q

def search(request):
    if request.method == "GET":
      search_terms = request.GET['title'] 
      search_terms = search_terms.split(',')
      #get rid of duplicates
      search_terms = set(search_terms)
      queryargs = [Q(title__contains=i) for i in search_terms]
      jobs = Job.objects.filter(*queryargs)

Answer 2

使用django.db.models.Q个对象。像这样：

from django.db.models import Q

def search(request):
   if request.method == "GET":
       search_terms = request.GET['title']
       search_filter = Q()
       for term in search_terms.split(','):
            search_filter |= Q(title__contains=term)

       jobs = Job.objects.filter(search_filter)

这将搜索任何条款（OR），以搜索所有条款（AND）而不是search_filter &= Q(title__contains=term)。
