可以使用**&或使用Q（）和&运行AND运算符**，如下所示：

# "store/views.py"

from .models import Blog
from django.db.models import Q
from django.http import HttpResponse

def test(request):

    # With "&"
                                                     # ↓ Here
    qs = Blog.objects.filter(post__contains="popular") & \
         Blog.objects.filter(post__contains="simple")
    print(qs)

    # With "Q()" and "&" 
                           # ↓ Here                    # ↓ Here
    qs = Blog.objects.filter(Q(post__contains="popular") & 
                             Q(post__contains="simple"))
    print(qs)              # ↑ Here

    return HttpResponse("Test")

然后，您可以得到下面的结果：

<QuerySet [<Blog: Python is popular and simple.>]> # With "&"
<QuerySet [<Blog: Python is popular and simple.>]> # With "Q()" and "&"
[22/Dec/2022 12:08:22] "GET /store/test/ HTTP/1.1" 200 9

并且，根据PostgreSQL的查询日志，有**AND运算符**，如下所示，您可以选中在PostgreSQL上，如何记录带有事务查询（如"BEGIN"和"COMMIT"）的查询

此外，您还可以使用**filter()、|或使用Q（）和|运行OR运算符**，如下所示：

# "store/views.py"

from .models import Blog
from django.db.models import Q
from django.http import HttpResponse

def test(request):

    # With "&"
                                                     # ↓ Here
    qs = Blog.objects.filter(post__contains="popular") | \
         Blog.objects.filter(post__contains="simple")
    print(qs)

    # With "Q()" and "&" 
                           # ↓ Here                    # ↓ Here     
    qs = Blog.objects.filter(Q(post__contains="popular") | 
                             Q(post__contains="simple"))
    print(qs)              # ↑ Here
                       
    return HttpResponse("Test")

然后，您可以得到下面的结果：

<QuerySet [<Blog: Python is popular and simple.>, <Blog: Java is popular and complex.>]>
<QuerySet [<Blog: Python is popular and simple.>, <Blog: Java is popular and complex.>]>
[22/Dec/2022 12:56:41] "GET /store/call_test/ HTTP/1.1" 200 9

其中，根据PostgreSQL的查询日志，有**OR操作符**，如下所示：

• 请注意，您不应使用**and或or来运行AND或OR运算符**，因为根据此答案，它们无法正常工作，实际上，只有**&和的示例|* * 所以你应该像我上面展示的那样使用**&和|**。
