陷入NoReverseMatch而呈现：反转为 '' 与参数 '（1）' 和关键字参数 '{}' 未找到

Question

我的观点：

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

它真的不够信息。但问题就在这里：

{% 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 - 它从你的模型代码取决于你的一般逻辑

Answer 2

异常值：在呈现时捕获NoReverseMatch ：未找到参数'（1，）'和关键字参数 '{'''与 ''相反的''。

它看起来像你的x.content.url_internal_django_link返回一个空字符串。

检查你的数据库或临时更改{% url %}标签：

{{ x.content.url_internal_django_link }} 

，看看有什么是存储，为什么你是从数据库得到空字符串。

Answer 3

我已经得到了同样的异常输出说不能“（93L）”和关键字参数没有找到。

检查urls.py，在那里你可以看到网址不提供there.So提供的网址，然后youre不去这个错误。

Answer 4

刚刚对我的应用程序有同样的问题。以下解决方案适用于我：

由于您使用{% url %}标记来生成视图链接，因此需要将应用程序的URL添加到项目的根URLConf模块（通过include（）调用）。如果您将{% url %}标记与您尚未在项目中设置的URL名称一起使用，则它将无法找到正确的URL并仅返回空字符串而不是URL。

所以基本上问题是，你正在寻找了URL必须在项目的urls.py，否则Django的不能找到和跟踪它。

Answer 5

另一种可能性是URL的正则表达式字符串与您的请求不匹配。用户名用户名
