渲染时捕获NoReverseMatch:反向''带参数'(1,)'和关键字参数'{}'未找到

Question

我的看法 :

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

我的应用程序遇到了同样的问题.以下为我解决了这个问题:

因为您使用{% url %}标记生成视图的链接,所以需要将应用程序的URL添加到项目的根URLConf模块(通过include()调用).如果您使用{% url %}带有尚未在项目中设置的URL名称的标记,则它将无法找到正确的URL,只会返回空字符串而不是URL.

所以基本上问题是你正在查找的url必须在项目的urls.py中,否则Django无法找到并跟踪它.

Answer 2

这确实是信息不够。但问题就在这里：

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

可能你需要的是：

{% extends "base.html" %}

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

{% endblock %}

但我不确定 - 这取决于你的模型代码和你的一般逻辑
