Django HttpResponsponse 带有内参数的中导
原标题:Django HttpResponseRedirect with int parameter

我想从登录视图通过一个int参数 (user_id ) 到另一个视图。 这在 HttpResponsponseRepirect 中是可能的吗?

return HttpResponseRedirect("/profile/?user_id=user.id")

虽然我的内裤是:

(r ^profile/(?P<user_id>d+)/$ ,  ... )

但我不知道这是否正确 有什么建议吗?

最佳回答

这显然不是正确的方式, 因为您创建的 URL 与您的 urlconf 中的 URL 不匹配 。

这样做的正确方式是依靠决哥来为您这样做。 如果您给您的 URL 定义一个名称 :

urlpatterns += patterns(  , 
    url(r ^profile/(?Pd+)/$ ,   ... , name= profile ),
)

然后您就可以使用 django.core.urlresolvers. reverse 来用您的参数生成 URL :

redirect_url = reverse( profile , args=[user.id])
return HttpResponseRedirect(redirect_url)

请注意,在您的 URL 中使用 kwargs 而不是 args 更好, 但我保持了原样 。

问题回答

最后,我将上述答复合并为行动:

url = reverse( profile , kwargs={  user_id : user.id })
return HttpResponseRedirect(url)

url(r ^profile/(?P<user_id>d+)/$ ,  ... , name= profile )

和it worked perfectly.

谢谢!

这是可能的,但最好将 URL 倒转,然后重定向到 URL:

url = reverse( name_of_url , kwargs={  user_id : user.id })
return HttpResponseRedirect(url)

您应该确保您的 URL conf 在其中有一个命名参数( 在我上面的例子中, 它是一个叫做 user_ id 的参数 。
