Question

我正在尝试从我的数据库中删除Job对象，并且我一直收到错误：

TypeError at /minion/deleteJob/

以下是我用来尝试删除作业的代码：

#deletes the selected job from the database
def deleteJob(request, name):
    j = Job.objects.get(pk=3)
    Job.objects.filter(name=name).delete()
    return render_to_response('Minion/detail')

如果有人知道导致这个错误的原因似乎是源于python库，我将非常感激。

编辑：urls.py

from django.conf.urls import patterns, include, url
from django.views.generic import DetailView, ListView
from django.conf.urls.defaults import *
from Minion.models import Job

urlpatterns = patterns('Minion.views',
    # URLs for the MinionUI app
    url(r'^$', 'home'),
    url(r'^index/$', 'detail'),
    url(r'^add/$', 'add'),
    url(r'^output/$', 'output'),
    url(r'^cal/$', 'calendarTest'),
    url(r'^addJobData/$', 'addJobData'),
    url(r'^deleteJob/$', 'deleteJob'),
)

为了记录，我不太了解正则表达式，所以如果这里有明显的错误，请耐心等待。

url.py中的错误网址

看起来应该是这样的：

(r'^/minion/deleteJob/(\w+)/$', 'deleteJob'),

或者如果您还有数字：

(r'^/minion/deleteJob/([a-zA-Z0-9\-\s]+)/$', 'deleteJob'),

如何在django中使用delete（）表示模型
