Django错误语法错误：无效语法

Question

看来我卡住了。我需要你的帮助来修正这个错误。 我觉得网址上的正则表达式是烂的。任何帮助都将不胜感激。在

这是错误：

File "/Users/cohen/Documents/project/sanctions/batches/urls.py", line 2, in from . import views File "/Users/cohen/Documents/project/sanctions/batches/views.py", line 23 def detail_businessname(request): ^ SyntaxError: invalid syntax

以下是我的模型：

以下是我的观点：

^{pr2}$

这些是网址：

from django.conf.urls import url
from . import views

urlpatterns = [
    # /batches/
    url(r'^$', views.index, name='index'),

    # /batches/2
    url(r'^(?P<batches_id>[0-9]+)/$',views.detail, name="detail"),

    # businessname/1
    url(r'^(?P<businessname_id>[0-9]+)/$',views.detail_businessname, name="detail_businessname"),

    # individuals/1
    url(r'^(?P<individuals_id>[0-9]+)/$', views.detail_individuals, name="detail_individuals"),

非常感谢你， 科恩

你错过了封闭的胸罩

return HttpResponse("<h2>Details for Batches ID:"  + str(BatchNumber + "</h2"))
