NoReverseMatch Django url问题

Question

我正在尝试在我的 django 项目中实现一个典型的 url，但是我不断收到错误消息。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>

MODELS.PY

class Profile(models.Model):
    user = models.OneToOneField(User, on_delete=models.CASCADE)
    slug = models.SlugField(blank=True, unique=True)

观点。PY

def dashboard_view(request, slug):
    userprofile = Profile.objects.get(slug=slug)

    print(userprofile.slug)
    return render(request, 'userprofile/home.html', context)

        'page_name': 'Profile',
        'form': form
    }
    return render(request, 'userprofile/profile.html', context)

URLS.PY

app_name = 'userprofile'

Answer 1

您的上下文字典有profile 键：'profile': user_profile_detail,。所以在模板中你应该使用profile 而不是user_profile_detail：

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