Django：Bootstrap 按钮链接不起作用

Question

我在 Django 的民意调查应用程序中创建了一个链接，看起来我的按钮链接不起作用。我在这里做的错误是什么？

我的 urls.py 是

from django.conf.urls import url

from . import views

app_name = 'polls'

urlpatterns = [
    # ex: /polls/
    #url(r'^$', views.index, name='index'),
    url(r'^$', views.IndexView.as_view(), name='index'),


    url(r'^login/$', views.LoginView.as_view(), name='login'),

    # ex: /polls/5/
    # the 'name' value as called by the {$ url $} template tag
    #url(r'^(?P<question_id>[0-9]+)/$', views.detail, name='detail'),
    url(r'^(?P<pk>[0-9]+)/$', views.DetailView.as_view(), name='detail'),

    # ex: /polls/5/results/
    #url(r'^(?P<question_id>[0-9]+)/results/$', views.results, name='results'),
    url(r'^(?P<pk>[0-9]+)/results/$', views.ResultsView.as_view(), name='results'),

    # ex: /polls/5/vote/
    url(r'^(?P<ballot_id>[0-9]+)/vote/$', views.vote, name='vote'),

]

我创建了这样的按钮和链接

<button type="submit" class="btn btn-primary"><a href="{% url 'polls:index'  %}"></a>
  {% bootstrap_icon "home" %}
</button>
 <button type="submit" class="btn btn-primary"><a href="{% url 'polls:login'  %}"></a>
  {% bootstrap_icon "user" %} User Login
</button>

在检查员中它看起来像

对此有2种解决方案：

要么放置 的<a>外部<button>，如下所示：

<a href="{% url 'polls:index'  %}">
    <button class="btn btn-primary">{% bootstrap_icon "home" %}</button>
</a>

或者只留下<a>（并删除<button>），如下所示：

<a href="{% url 'polls:index'  %}" class="btn btn-primary">{% bootstrap_icon "home" %}</a>
