Question

我在Django应用程序中遇到一个小问题而无法弄清楚它有什么问题。我有一个从前端成功发送的POST请求，django控制台也会点击URL并提供状态代码200.但问题是该视图根本没有被触发。

/urls.py

urlpatterns = [
    url('addition/', views.addition_task, name='addition'),
    url('addition-task-status/', views.addition_task_status, name='addition_task_status'),
    url('', views.algorithm_index, name='algorithm_index'),
    url('outlier/', views.run_outlier_task, name='run_outlier'),
    url('outlier-task-status/', views.outlier_task_status, name='outlier_task_status'),
    ]

/views.py

@csrf_exempt
def run_outlier_task(request):
    print("I'm here")

    if request.method == "POST":
        print("Request is post")
        metric = request.POST["metric_variable"]
        print(metric)
        path = ['MKT', 'CP_MANUFACTURER', 'CP_FRANCHISE', 'CP_BRAND', 'CP_SUBBRAND']
        drivers = ['Cumulative_Distribution_Pts', 'pct_Stores_Selling', 'Baseline_RASP_per_EQ']

        if request.session.get('file_path', None) == None:
            file_name = "anon_cntr_out_br.csv"
        else:
            file_name = request.session.get('file_path', None)

        outlier_task = outlier_algorithm.delay(path, metric, file_name, drivers)
        return HttpResponseRedirect(reverse("outlier_task_status") + "?job_id=" + outlier_task.id)
    else:
        return HttpResponse("GET Request")

def outlier_task_status(request):
    if 'job_id' in request.GET:
        job_id = request.GET['job_id']
        job = AsyncResult(job_id)
        data = job._get_task_meta()
        return HttpResponse(json.dumps(data['result']))
    else:
        HttpResponse("No job ID given")

/templates/algorithm.html

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Algorithms</title>
</head>
<body>
<div>
    <form action="{% url 'run_outlier' %}" method="post">
        {% csrf_token %}
        <input type="text" name="metric_variable">
        <input type="submit" value="Run algo with default file and attributes" />
    </form>
</div>
</body>
</html>

如果您能解决此问题，请与我们联系。我没有提到addition_task和addition_task_status视图，但它们技术上95％相同并且它们正在工作。提前谢谢。

algorithm_index的空URL匹配所有内容，因此永远不会调用异常值和异常值 - 任务 - 状态视图。你应该使用锚点：

url('^$', views.algorithm_index, name='algorithm_index'),

或者，在Django 2.0中使用新的path语法。
