jquery Ajax發佈更新視圖中的django sesions

Question

我從我的表單字段發送值，以便將它們存儲在django中的會話中。我正在做下面的事情，但它沒有在django中接收POST中的數據。

<script type="text/javascript"> 

    var eventID = $('#id_eventID').val(); 
    var start = $('#id_start').val(); 
    $('a').click(function() { 
    console.log("Inside click");  
    $.post({ 
     url: "/update_session/", 
     type: "POST", 
     data: {eventID: eventID, start: start}, 
     success: function(response){}, 
     complete: function(){}, 
     error: function (xhr, textStatus, thrownError){ 
     alert("Error in ajax post"); 
     } 
    }); 
    }); 
</script> 

<a href="Event/{{field.name}}"> Add signal</a> 

我想要這個腳本執行，當我點擊上面的鏈接，然後打開一個新的窗體。所以，當我回到原始頁面（填寫完表格之後）時，我希望能夠檢索將存儲在會話中的所有數據（以我上面的方式）。

在我view.py我有以下的，

def update_session(request): 
    print request.POST 
    if request.is_ajax(): 
    try: 
    request.session['eventID'] = request.POST['eventID'] 
    request.session['start'] = request.POST['start'] 
    except KeyError: 
    return HttpResponse('Error') 
    else: 
    raise Http404 

有了這個沒有在我的Django吡嗪酰胺得到打印。它顯示一個空的Querydict {}。

另外，我的方法是否正確實現了所需的功能？或者是否有更好的方式來實現這一點..我是一個網頁開發新手.. 所以，一些來源或提示將是偉大的！

更新： * urls.py *

from django.conf.urls import patterns, url 
from EiEventService import views 

urlpatterns = patterns('', 
    url(r'^$', views.event_view), 
    url(r'^create/$', views.event_create), 
    url(r'^eventSignals/$', views.eventSignal_create), 
    url(r'^Intervals/$', views.interval_create), 
    url(r'^eventBaseLine/$', views.EventBaseline_create), 
    #url(r'^(?P<event_id>.*)/$', views.editEvent), 
) 

與視圖中的變化和通過limelights提到在urls.py加入。 我收到以下錯誤。整個回溯是，

Answer 1

你必須在/update_session/網址添加到您的urls.py - 這是你遇到的首要問題。這也是您的腳本未到達服務器的原因。

url(r'^/update_session/$', views.update_session) 

會是這種網址模式。

此外，你具有將在你的開發出現以後其他一些問題，所以我肯定會推薦你通過tutorial here
