通过 URL 传递参数时出现 Django TypeError

Question

您好，我在 Django（最新版本）中收到以下错误：

TypeError at /post/1/
post() got an unexpected keyword argument 'post_id'

当我点击主页上的链接查看帖子时会发生这种情况，我试图传递帖子的 ID（我使用的是默认的 [隐藏] 主键，而不是我自己的自定义主键）

这就是我的 urls.py 在索引和帖子页面中的样子：

from django.conf.urls.defaults import patterns, include, url
from journal.models import Post


# Uncomment the next two lines to enable the admin:
from django.contrib import admin
admin.autodiscover()

urlpatterns = patterns('journal.views',
    (r'^$', 'index'),
    (r'^post/(?P<id>\d+)/$', 'post'),

这是我的views.py：

from django.http import HttpResponse
from journal.models import Post
from django.template import Context, loader
import os

# Hardcoded Varibles
SITE_ROOT = os.path.join(os.path.dirname(__file__))

# Create your views here.
def index(request):
    latest_post_list = Post.objects.all().order_by('-pub_date')[:10]
    t = loader.get_template(os.path.join(SITE_ROOT, 'templates', 'index.html'))
    c = Context({
    'latest_post_list': latest_post_list,
    })
    return HttpResponse(t.render(c))

def post(request, id):
    return HttpResponse("Hello this is post %" %(post_id))

Answer 1

改变

def post(request, id):
    return HttpResponse("Hello this is post %" %(post_id))

到

def post(request, id):
    return HttpResponse("Hello this is post %s" % id)

而且我怀疑它会更好一点！
