我想将表的ID传递给我的函数,但我不知道发生了什么。 如果我硬编码身份证号码工作,如果我使用(?Pd +)与D +,因此它使用尽可能多的数字,如在教程中。不起作用。这应该是不同的?django 1.7如何将参数传递到函数正则表达式
谢谢你们。
我的网址
from django.conf.urls import patterns, include, url
from polls import views
urlpatterns = patterns('',
#url(r'^main_site/$', views.main_site),
url(r'^vote/$', views.vote),
url(r'^stadistics/$', views.stadistics),
# using it like this doesn't work
url(r'^vote/Restaurant_Info/(?P<rest_id>d+)/$', views.restaurant_menu),
#testing the info of the restaurant
# hard coding the id of the restaurant does work
url(r'^vote/Restaurant_Info/4/$', views.restaurant_menu),
我看来
def restaurant_menu(request, rest_id="0"):
response = HttpResponse()
try:
p = Restaurant.objects.get(id=rest_id)
response.write("<html><body>")
response.write("<p>name of the restaurant</p>")
response.write(p.name)
response.write("</body></html>")
except Restaurant.DoesNotExist:
response.write("restaurant not found")
return response
感谢您的解释,我因子评分是Django的,但我要寻找到RE,它的工作原理为字符串以同样的方式?像url(r'^/vote/thanks /(?P \ w +)/ $',views.thanks), –
