在呈现时捕获NoReverseMatch：反向为''与参数'（1，）'和关键字参数'{}'未找到 [英] Caught NoReverseMatch while rendering: Reverse for '' with arguments '(1,)' and keyword arguments '{}' not found

问题描述

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 %}

推荐答案

刚刚遇到与我的应用程序相同的问题。以下内容为我解决了问题：

Just had the same problem with my app. The following solved it for me:

由于您使用 {％url％} 标签来生成链接到视图，您需要将应用程序的URL添加到项目的根URLConf模块（通过include（）调用）。如果您使用项目中尚未设置的URL名称的 {％url％} 标记，则无法找到正确的URL并且将简单地返回一个空字符串而不是URL。

Because you’re using the {% url %} tag to generate the link to the view, you need to add the URLs for the application to your project’s root URLConf module (via include() calls). If you use the {% url %} tag with a URL name that you haven’t yet set up in your project, it won’t be able to find the correct URL and will simply return an empty string instead of a URL.

所以基本上问题是你要查找的url必须在你的项目的urls.py中否则Django找不到并追踪。

So basically the problem is that the url you're looking up must be in the urls.py of your project, otherwise Django can't find and trace it.
