django中的bootstrap3选项卡

Question

我想实施 Bootstrap3选项卡 在我的应用程序中，该应用程序按州显示学校数据。因此，如果您转到示例com.com/ma/，您将看到马萨诸塞州和标签状态的信息，以按年级排序。

我已经在使用QuerySet按状态过滤，因此仅出现“ ma”结果。而且我可以在其中一个选项卡中显示所有数据，但不能将其用于多个选项卡。为了简单起见，我只想在这里为“全部”和“高中”做标签。

这是我的 模型：来自django.db导入模型

class School(models.Model):
    school_name = models.CharField(max_length=200)
    location_state  = models.CharField(max_length=2)
    grades = models.CharField(max_length=20)

这是我的模板 state.py:

{% extends 'base.html' %}

{% block content %}

<h2>{{ state }}</h2> #This works and shows the state based on the URL

<div class="row">
    <div class="col-12 col-sm-12 col-lg-12">
    <ul class="nav nav-tabs" id="myTab">
        <li class="active"><a href="#all">All</a></li>
        <li><a href="#high">High School</a></li>
    </ul>
    </div>

{% for school in schools_by_state %}
<div id="content" class="tab-content">
    <div class="tab-pane active" id="all">
    <ul>
        <li>{{ school.school_name }}</li>
    </ul>
    </div>
    <div class="tab-pane" id="high">
    <ul>
        <li>{{ ???highschool??? }}</li>
    </ul>
    </div>  
</div><!-- end content -->
</div><!-- end row -->
{% endfor %}

{% endblock content %}

这是我的 Views.py:

from django.views.generic import ListView

from .models import School

class StateListView(ListView):
    model = School
    template_name = 'state.html'
    context_object_name = 'schools_by_state'

    def get_queryset(self):
        state_list = self.kwargs['location_state']
        return School.objects.filter(location_state=state_list)

    def get_context_data(self, **kwargs):
        context = super(StateListView, self).get_context_data(**kwargs)
        context.update({'state': self.kwargs['location_state']})
        return context

为了完整，这是 urls.py 为此观点：

url(r'^(?P<location_state>[A-Z]{2})/$', StateListView.as_view()),

我不相信我想在此处使用多个QuerySet，而是想在“高中”的视图中找到一种在Contection_Data中添加其他过滤器的方法，然后我可以将其添加到模板中。但是，我尝试添加其他上下文过滤器的尝试都失败了。想法？

Answer 1

您只需在上下文中添加一个新的QuerySet：

def get_context_data(self, **kwargs):
    context = super(StateListView, self).get_context_data(**kwargs)
    context.update({'state': self.kwargs['location_state']})

    context['schools_highschool'] = context['schools_by_state'].filter(grades='9-12')

    return context

然后循环 schools_highschool 在模板中。我认为您的模板也有些偏离。也许这样做：

{% extends 'base.html' %}

{% block content %}

<h2>{{ state }}</h2> #This works and shows the state based on the URL

<div class="row">
    <div class="col-12 col-sm-12 col-lg-12">
        <ul class="nav nav-tabs" id="myTab">
            <li class="active"><a href="#all">All</a></li>
            <li><a href="#high">High School</a></li>
        </ul>
    </div>


    <div id="content" class="tab-content">

        <div class="tab-pane active" id="all">
            <ul>
                {% for school in schools_by_state %}
                    <li>{{ school.school_name }}</li>
                {% endfor %}
            </ul>
        </div>

        <div class="tab-pane" id="high">
            <ul>
                {% for school in schools_highschool %}
                    <li>{{ school.school_name }}</li>
                {% endfor %}
            </ul>
        </div>  

    </div><!-- end content -->

</div><!-- end row -->

{% endblock content %}

JPROFFITTS答案是正确的，但是您也可以根据模板中的一个查询设置过滤：

<div id="content" class="tab-content">
    <div class="tab-pane active" id="all">
    <ul>
        {% for school in schools_by_state %}
        <li>{{ school.school_name }}</li>
        {% endfor %}
    </ul>
    </div>
    <div class="tab-pane" id="high">
    <ul>
        {% for school in schools_by_state %}
         {% if school.grade == "9-12" %}
        <li>{{ school.school_name }}</li>
         {% endif %}
        {% endfor %}
    </ul>
    </div>  
</div><!-- end content -->
