Django 中的 Bootstrap3 选项卡
[英] Bootstrap3 tabs in Django
本文介绍了Django 中的 Bootstrap3 选项卡的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我想在我的应用中实现 Bootstrap3 标签，它按州显示学校数据.因此，如果您访问 example.com/ma/，您将看到马萨诸塞州的信息和按年级排序的选项卡.
我已经在使用查询集按状态过滤，以便在 example.com/ma/上只显示ma"结果.我可以在其中一个选项卡中显示所有数据，但无法针对多个选项卡过滤掉它.为简单起见，我只想在这里为全部"和高中"做标签.
这是我的models.py:从 django.db 导入模型
class School(models.Model):school_name = models.CharField(max_length=200)location_state = models.CharField(max_length=2)等级 = 模型.CharField(max_length=20)
这是我的 state.py 模板:
{% 扩展 'base.html' %}{% 块内容 %}<h2>{{ state }}</h2>#This 工作并显示基于 URL 的状态<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">高中</a></li>
{% for school_by_state %}<div id="content" class="tab-content"><div class="tab-pane active" id="all"><ul><li>{{ school.school_name }}</li>
<div class="tab-pane" id="high"><ul><li>{{ ???高中???}}
</div><!-- 结束内容--></div><!-- 结束行-->{% 结束为 %}{% 端块含量 %}
这是我的views.py:
from django.views.generic import ListView从 .models 导入学校类 StateListView(ListView):模型 = 学校模板名称 = 'state.html'context_object_name = 'schools_by_state'def get_queryset(self):state_list = self.kwargs['location_state']返回 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']})返回上下文
为了完整起见，这里是此视图的 urls.py:
url(r'^(?P[A-Z]{2})/$', StateListView.as_view()),
我不相信我想在这里使用多个查询集，而是找到一种方法在highschool"的视图中向我的 context_data 添加额外的过滤器，然后我可以将其添加到我的模板中.然而，我尝试添加额外的上下文过滤器都失败了.想法?
解决方案
你可以在上下文中添加一个新的查询集:
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')返回上下文
然后在模板中循环schools_highschool.我觉得你的模板也有点不对.也许这样做:
{% 扩展 'base.html' %}{% 块内容 %}<h2>{{ state }}</h2>#This 工作并显示基于 URL 的状态<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">高中</a></li>
<div id="content" class="tab-content"><div class="tab-pane active" id="all"><ul>{% for school_by_state %}<li>{{ school.school_name }}</li>{% 结束为 %}
<div class="tab-pane" id="high"><ul>{% for school in school_highschool %}<li>{{ school.school_name }}</li>{% 结束为 %}
</div><!-- 结束内容--></div><!-- 结束行-->{% 端块含量 %}
I want to implement Bootstrap3 tabs in my app, which displays school data by state. So if you go to example.com/ma/ you will see information for the state of Massachusetts and tabs to sort by grade level.
I am already using the queryset to filter by state so that on example.com/ma/ only "ma" results appear. And I can show ALL data in one of the tabs, but can't filter it out for multiple tabs. To keep it simple, I just want to do tabs for "All" and "High School" here.
Here is my models.py:
from django.db import models
class School(models.Model):
school_name = models.CharField(max_length=200)
location_state = models.CharField(max_length=2)
grades = models.CharField(max_length=20)
Here is my template for 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 %}
And here is my 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
For completeness, here is the urls.py for this view:
url(r'^(?P<location_state>[A-Z]{2})/$', StateListView.as_view()),
I don't believe I want to use multiple querysets here, but instead find a way to add an additional filter to my context_data in the view for "highschool" which I can then add to my template. However my attempts to add additional context filters have all failed. Thoughts?
解决方案
You can just add a new queryset to the context:
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
Then loop schools_highschool in the template. I think your template is a little off too. Maybe do this:
{% 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 %}
