陷入NoReverseMatch而呈現：反轉爲 '' 與參數 '（1）' 和關鍵字參數 '{}' 未找到

Question

我的觀點：

def display(request): 
    feed = SoukFeedMaster.objects.filter(person = request.user) 
    return render(request, 'soukfeed/display.html', {'feed' : feed ,}) 

我的模板：

{% extends "base.html" %} 

    {% block content %}  
    {% for x in feed %} 
     {% load url from future %} 
     <a href="{% url x.content.url_internal_django_link x.content.id %}"> {{x.content.content}} </a> 
     <br/> 
    {% endfor %} 

    {% endblock %}

Answer 1

它真的不夠信息。但問題就在這裏：

{% url x.content.url_internal_django_link x.content.id %} 

可能是你需要的是：

{% extends "base.html" %} 

{% block content %}  
{% for x in feed %} 
    <a href="{{ x.content.get_absolute_url }}"> {{x.content.content}} </a> 
    <br/> 
{% endfor %} 

{% endblock %} 

但我不知道 - 它從你的模型代碼取決於你的一般邏輯

Answer 2

異常值：在呈現時捕獲NoReverseMatch ：未找到參數'（1，）'和關鍵字參數 '{'''與 ''相反的''。

它看起來像你的x.content.url_internal_django_link返回一個空字符串。

檢查你的數據庫或臨時更改{% url %}標籤：

{{ x.content.url_internal_django_link }} 

，看看有什麼是存儲，爲什麼你是從數據庫得到空字符串。

Answer 3

我已經得到了同樣的異常輸出說不能「（93L）」和關鍵字參數沒有找到。

檢查urls.py，在那裏你可以看到網址不提供there.So提供的網址，然後youre不去這個錯誤。

Answer 4

剛剛對我的應用程序有同樣的問題。以下解決方案適用於我：

由於您使用{% url %}標記來生成視圖鏈接，因此需要將應用程序的URL添加到項目的根URLConf模塊（通過include（）調用）。如果您將{% url %}標記與您尚未在項目中設置的URL名稱一起使用，則它將無法找到正確的URL並僅返回空字符串而不是URL。

所以基本上問題是，你正在尋找了URL必須在項目的urls.py，否則Django的不能找到和跟蹤它。

Answer 5

另一種可能性是URL的正則表達式字符串與您的請求不匹配。用戶名用戶名
