Django contrib 消息，不打印 Box 标签

Question

我是 Django 的新手，我构建了一个小应用程序，我想在单击按钮时显示一条消息。消息正确显示到网络应用程序，但它只显示文本，不显示颜色框（绿色表示成功，红色表示错误）。我在 DOCS 和 Whosebug 上搜索了很多，但没有找到答案。谢谢你的帮助

views.py

from django.contrib import messages

def send_sms(request):
    if request.method == 'POST':
        form = ClientInfo(request.POST)
        if form.is_valid():
            try:
                sms = Client.messages.create(
                    from_="+XXXXXXXXXX",
                    body=mess,
                    to=sms_client
                )
                send = sms.sid

                messages.add_message(request, messages.SUCCESS, 'Succes! Message has been sent!')

            except:
                messages.error(request, 'Error! Message has not been sent!')

好的 - 我遗漏了一些部分，例如在 python 中导入库并触发 ajax 请求 - 如果您需要这些，请告诉我。否则，如果您坚持这种模式，您应该能够使用您的 Django 应用程序完成很多工作。

views.py:

# define behavior when requests are sent to 'send_message':
def SendMessage(request):

    # unpack request:
    status = request.POST['status']

    # set message depending on status:
    if status == True:
        message = 'Everything okay!'
    elif status == False:
        message = 'Something went wrong...'

    # pack context:
    context = json.dumps({
        'message' : message,
        'status' : status,
    })

    # return an HTTP response with context:
    return HttpResponse(context)

urls.py:

# route url to view function:
urlpatterns = [
    path('send_message/', views.SendMessage, name='send_message'),
]

模板：

// create ajax request:    
$.ajax({

    // send to url:
    url : "{% url 'send_message' %}",
    type : 'POST',

    // add data to post request:
    data : {
        'status' : // status is either true or false based on some logic
    },
    dataType    :'json',

    // this function executes if we get a succesfull response from the backend:
    success : function(context) { 

        // get the value of 'status' and 'message' that was set in the backend:
        var status = context.status
        var message = context.message

        if (status) {/* do something if status is true */ }
        else {/* do something if status is false */}
    },
});
