Django中的Bootstrap3選項卡

Question

我想在我的應用程序中實現Bootstrap3選項卡 ，該選項卡按州顯示學校數據。 因此，如果您轉到example.com/ma/，您將看到馬薩諸塞州的信息以及按年級排序的標簽。

我已經在使用queryset按狀態進行過濾，以便在example.com/ma/上僅顯示“ ma”結果。 而且我可以在其中一個標簽中顯示所有數據，但不能為多個標簽過濾掉它們。 為簡單起見，我只想在此處為“全部”和“高中”做標簽。

這是我的models.py ：從django.db導入模型

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

這是我的state.py模板：

{% 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 %}

這是我的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

為了完整起見 ，以下是此視圖的urls.py ：

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

我不相信我要在此處使用多個查詢集，而是找到一種方法在“高中”視圖中向我的context_data添加一個附加過濾器，然后將其添加到模板中。 但是，我添加其他上下文過濾器的嘗試均失敗了。 思考？

您可以將新的查詢集添加到上下文中：

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

然后在模板中循環schools_highschool 。 我認為您的模板也有些不足。 也許這樣做：

{% 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答案是正確的，但是您也可以根據模板中的這一查詢集進行過濾：

<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 -->
