在 django 中同时搜索用户的名字和姓氏

Question

我有一个网页，它显示用户的详细信息，例如他们的名字和姓氏、用户名、电子邮件等。但我只能在搜索栏中搜索用户的名字或姓氏，我该怎么做使用户能够输入用户的名字和姓氏并显示详细信息吗？

这就是我的网页如下图所示的样子（例如：员工姓名显示为 admin（名字）和 Tan（姓氏）：

views.py

@login_required()
def allstaff(request):
    search_post = request.GET.get('q')
    if (search_post is not None) and search_post:
        allusername = User.objects.filter(Q(first_name__icontains=search_post) | Q(last_name__icontains=search_post) | Q(
            username__icontains=search_post) | Q(email__icontains=search_post))
        if not allusername:
            allusername = User.objects.all().order_by("-date_joined")
    else:
        allusername = User.objects.all().order_by("-date_joined")

    page = request.GET.get('page')
    paginator = Paginator(allusername, 3)
    try:
        allusername = paginator.page(page)
    except PageNotAnInteger:
        allusername = paginator.page(1)
    except EmptyPage:
        allusername = paginator.page(paginator.num_pages)


    context = {'allusername': allusername, 'query': search_post}

    return render(request, 'allstaff.html', context)

allstaff.html

您可以使用Concat 数据库功能。 User.objects.annotate(full_name=Concat("first_name", V(" "), "last_name"))

from django.db.models import Value as V
from django.db.models.functions import Concat

@login_required()
def allstaff(request):
    search_post = request.GET.get('q')
    if (search_post is not None) and search_post:
        allusername = User.objects.annotate(full_name=Concat("first_name", V(" "), "last_name")).filter(Q(full_name=search_post)| Q(first_name__icontains=search_post) | Q(last_name__icontains=search_post) | Q(
            username__icontains=search_post) | Q(email__icontains=search_post))
        if not allusername:
            allusername = User.objects.all().order_by("-date_joined")
    else:
        allusername = User.objects.all().order_by("-date_joined")

    page = request.GET.get('page')
    paginator = Paginator(allusername, 3)
    try:
        allusername = paginator.page(page)
    except PageNotAnInteger:
        allusername = paginator.page(1)
    except EmptyPage:
        allusername = paginator.page(paginator.num_pages)


    context = {'allusername': allusername, 'query': search_post}

    return render(request, 'allstaff.html', context)
