我有一个ListView,从中我想使用DeleteView删除一些对象。我到目前为止所拥有的:
views.py
class BlockListView(ListView):
model= Classroom
def get_context_data(self, **kwargs):
context = super(BlockListView, self).get_context_data(**kwargs)
classroom_blocks = Classroom.objects.all()
context = {'classroom_blocks': classroom_blocks}
return context
list_classroom_view = BlockListView.as_view()
class BlockDeleteView(DeleteView):
model = Classroom
success_url = reverse_lazy('classroom:blocklist')
delete_classroom_view = BlockDeleteView.as_view()
urls.py
urlpatterns = [
path(r'^$', views.index, name='index'),
path('submitted', views.submitted, name='submitted'),
path('classup/', create_classroom_view, name='classroom'),
path('block/', views.block, name='block'),
path('blocklist/', list_classroom_view, name='blocklist'),
path(r'^(?P<pk>\d+)/blockDelete/$', delete_classroom_view, name='blockDelete'),
]
用于列表视图的模板:
{% for block in classroom_blocks %}
<li>{{ block.get_course_block_display }}<a href ="{% url 'classroom:blockDelete' block.id %}" class="button" style="color:#999999">DELETE</a></li>
{% empty %}
<li>No classes set up yet.</li>
{% endfor %}
确认删除模板:
{% block body %}
<h1>Confirm Delete</h1>
<form action="." method="post">{% csrf_token %}
<p>Are you sure you want to delete "{{ object.course_block }}"?</p>
<input type="submit" value="Confirm" />
</form>
{% endblock %}
从列表视图中单击删除按钮后,生成的URL为http://127.0.0.1:8000/classroom/%5E(%3FP89%5Cd+)/blockDelete/$
,这将指向确认删除页面。确认删除后,我收到Request URL: http://127.0.0.1:8000/classroom/%5E(%3FP89%5Cd+)/blockDelete/
答案 0 :(得分:1)
您正在使用path()
,因此您不应该使用正则表达式。将第一个和最后一个URL模式更改为:
path('', views.index, name='index'),
...
path('<int:pk>/blockDelete/', delete_classroom_view, name='blockDelete'),
现在,当您从列表视图中单击删除按钮时,应该将您带到/classroom/1/blockDelete/
之类的网址,并且提交表单时也不会出现404错误。
