NoReverseMatch Django URL问题

标签： django django-views

我正在尝试在我的django项目中实现一个典型的url，但是我一直收到错误信息。我检查了我在KWARGS中传递的网址，视图和html代码。我不知道这里出了什么问题，请帮忙？

home.html在模板中使用user_profile_detail

userprofile / home.html 

<div class="sidebar-fixed position-fixed side_nav_bar ">

    <a class="logo-wrapper waves-effect">
        <img src="/" class="img-fluid" alt="">
    </a>

    <div class="list-group list-group-flush">
        **<a href="{% url 'userprofile:dashboard' user_profile_detail.slug %}" class="list-group-item {% if request.path == dashboard %}active{% endif %} waves-effect">
            <i class="fa fa-pie-chart mr-3"></i>Dashboard
        </a>**

        <a href="{% url 'userprofile:profile' user_profile_detail.slug  %}" class="list-group-item {% if request.path == profile %}active{% endif %} list-group-item-action waves-effect">
            <i class="fa fa-user mr-3"></i>Profile</a>

        <a href="{% url 'userprofile:watchlist' user_profile_detail.slug  %}" class="list-group-item {% if request.path == watchlist %}active{% endif %} list-group-item-action waves-effect">
            <i class="fa fa-eye mr-3" aria-hidden="true"></i>WatchList</a>

        <a href="{% url 'userprofile:blog' user_profile_detail.slug  %}" class="list-group-item {% if request.path == blog %}active{% endif %} list-group-item-action waves-effect">
            <i class="fa fa-book mr-3" aria-hidden="true"></i>My Blogs</a>

        <a href="{% url 'userprofile:history' user_profile_detail.slug  %}" class="list-group-item {% if request.path == history %}active{% endif %} list-group-item-action waves-effect">
            <i class="fa fa-history mr-3" aria-hidden="true"></i>My Browsing History</a>
    </div>

</div>

您的上下文字典具有profile键：'profile': user_profile_detail,。因此，在模板中，您应该使用profile而不是user_profile_detail：

"{% url 'userprofile:dashboard' profile.slug %}"
