如何在Django中為模型使用delete（）

Question

我正在嘗試從數據庫中刪除Job對象，但不斷出現錯誤：

TypeError at /minion/deleteJob/

deleteJob() takes exactly 2 arguments (1 given)

Request Method:     GET
Request URL:    http://127.0.0.1:8000/minion/deleteJob/

這是我用來嘗試刪除作業的代碼：

#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')

如果有人知道是什么原因導致這個錯誤似乎源自python庫，我將不勝感激。

編輯：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'),
)

根據記錄，我不太了解正則表達式，所以如果這里有明顯的錯誤，請多包涵。

Answer 1

url.py中的網址錯誤

它看起來應該像這樣：

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

或者如果您還有數字：

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