使用 Django 的 HTML 模板中的组权限

Question

我的项目遇到了一点问题。我想将我的Django website 中的一部分授权给除一个（超级管理员）之外的所有组（访客、客户……）。

这是我的 HTML 模板：

        <!-- Home tab -->

        <ul class="nav navbar-nav">
            <li><a href="{% url "accueil" %}"> <span class="glyphicon glyphicon-home"></span> Accueil </a></li>

            {% if request.user|has_group:"admin" %}

            <li class = "dropdown">
                <a href = "#" class = "dropdown-toggle" data-toggle = "dropdown">
                    Informations Mairie
                <b class = "caret"></b>
                </a>
                <ul class = "dropdown-menu">
                    <li><a href = "{% url "Mairieform" %}"> <span class="glyphicon glyphicon-pencil"></span> Créer/Editer les informations de la Mairie </a></li>
                    <li><a href = "{% url "Mairieresume" %}"> <span class="glyphicon glyphicon-home"></span> Consulter les informations de la Mairie </a></li>
                </ul>
            </li>

            <li class = "dropdown">
                <a href = "#" class = "dropdown-toggle" data-toggle = "dropdown">
                    Actes Etat Civil
                <b class = "caret"></b>
                </a>
                <ul class = "dropdown-menu">
                    <li><a href = "{% url "home" %}"> <span class="glyphicon glyphicon-user"></span> Fiches Individuelles </a></li>
                    <li><a href = "{% url "BChome" %}"> <span class="glyphicon glyphicon-baby-formula"></span> Actes de Naissance </a></li>
                    <li><a href = "{% url "BCnotfound" %}"> <span class="glyphicon glyphicon-heart"></span> Actes de Mariage </a></li>
                    <li><a href = "{% url "BCnotfound" %}"> <span class="glyphicon glyphicon-fire"></span> Actes de Divorce </a></li>
                    <li><a href = "{% url "BCnotfound" %}"> <span class="glyphicon glyphicon-alert"></span> Actes de Décès </a></li>
                </ul>
            </li>
        </ul>

            {% elif request.user |has_group:"visiteur","employé", "officier", "maire" %}

        <ul class="nav navbar-nav">
            <li><a href="{% url "accueil" %}"> <span class="glyphicon glyphicon-home"></span> Accueil </a></li>
            <li class = "dropdown">
                <a href = "#" class = "dropdown-toggle" data-toggle = "dropdown">
                    Informations Mairie
                <b class = "caret"></b>
                </a>
                <ul class = "dropdown-menu">
                    <li><a href = "{% url "Mairieresume" %}"> <span class="glyphicon glyphicon-home"></span> Consulter les informations de la Mairie </a></li>
                </ul>
            </li>

            <li class = "dropdown">
                <a href = "#" class = "dropdown-toggle" data-toggle = "dropdown">
                    Actes Etat Civil
                <b class = "caret"></b>
                </a>
                <ul class = "dropdown-menu">
                    <li><a href = "{% url "home" %}"> <span class="glyphicon glyphicon-user"></span> Fiches Individuelles </a></li>
                    <li><a href = "{% url "BChome" %}"> <span class="glyphicon glyphicon-baby-formula"></span> Actes de Naissance </a></li>
                    <li><a href = "{% url "BCnotfound" %}"> <span class="glyphicon glyphicon-heart"></span> Actes de Mariage </a></li>
                    <li><a href = "{% url "BCnotfound" %}"> <span class="glyphicon glyphicon-fire"></span> Actes de Divorce </a></li>
                    <li><a href = "{% url "BCnotfound" %}"> <span class="glyphicon glyphicon-alert"></span> Actes de Décès </a></li>
                </ul>
            </li>
        </ul>

            {% endif %}

如您所见，我只有一个选项卡，除超级管理员组外，所有组都必须不可见。它适用于超级管理员，但我的问题是：

我如何写这行：{% if request.user|has_group:"admin" %} for ：

• 除超级管理员外的所有组
• 或访客、客户……

类似这样的：

{% elif request.user |has_group:"visiteur","employé", "officier", "maire" %}

谢谢！

最好在视图中执行此操作。

class MyView(ViewClass):
    def get_context_data(self, *args, **kwargs):
        context = super().get_context_data(*args, **kwargs)
        if self.request.user.is_superuser:
            context['show_tab'] = True
            return context
        return context

那你就可以访问这个模板了

{% if show_tab %}
  <myHtml/>
{% endif %}

我上面的回答是针对您是否使用基于类的视图。如果您使用基于函数的视图，这可能看起来更熟悉。

def my_view(request):
    context = {}
    if request.user.is_superuser<group logic>:
         context['show_tab'] = True
         return context
    return render(request, 'mytemplate.html', context)

这里的重点是您可以将字典（如上下文）传递到视图中，以使其在模板中可供您使用。
