Models_Class 有choice,如何显示其中文

 

 

 

方式二：用模板语言

- get_server_status_id_display( );  #局限性：条件必须是对象QuerySet[对象，对象]

代码：

def test(request):
    """
    模板语言显示 choice
    :param request:
    :return:
    """

    server_list = models.Server.objects.all()
    for row in server_list:
        print(row.id,row.hostname,
              "===",
              row.server_status_id,row.get_server_status_id_display() )
    return render(request, 'test.html', {'server_list': server_list})

 

<ul>
    {% for row in server_list %}
        <li>{{ row.hostname }}---{{ row.get_server_status_id_display }}</li>
    {% endfor %}

</ul>

 

 

-yield实现

代码:

def xx(data_list):
    for row in data_list:
        for item in models.Server.server_status_choices:
            if item[0] == row['server_status_id']:
                row['server_status_id_name'] = item[1]
                break
            print('***',item)
        yield row


def test(request):
    """
    模板语言显示 choice
    :param request:
    :return:
    """

    data_list =models.Server.objects.all().values('hostname','server_status_id')
    print(data_list)

    return render(request,'test.html',{'server_list':xx(data_list)})  #注意xx()

 

<ul>

    {% for row in server_list %}
        <li>{{ row.hostname }}---{{ row.server_status_id_name }}</li>
    {% endfor %}

</ul>
