我有一个模型如下.
class TankJournal(models.Model):
user = models.ForeignKey(User)
tank = models.ForeignKey(TankProfile)
ts = models.IntegerField(max_length=15)
title = models.CharField(max_length=50)
body = models.TextField()
我还有一个上述模型的模型表格如下.
class JournalForm(ModelForm):
tank = forms.IntegerField(widget=forms.HiddenInput())
class Meta:
model = TankJournal
exclude = ('user','ts')
我想知道如何设置该坦克隐藏字段的默认值.这是我到目前为止显示/保存表单的函数
def addJournal(request, id=0):
if not request.user.is_authenticated():
return HttpResponseRedirect('/')
# checking if they own the tank
from django.contrib.auth.models import User
user = User.objects.get(pk=request.session['id'])
if request.method == 'POST':
form = JournalForm(request.POST)
if form.is_valid():
obj = form.save(commit=False)
# setting the user and ts
from time import time
obj.ts = int(time()) …我在d3中有以下简单的行但是没有问题试图弄清楚如何传递data2并更新行以反映更改.

我有一个kubernetes集群,我试图从头开始构建而不使用他们的构建脚本.除了自动缩放之外,几乎所有东西都在工作.由于某种原因,控制管理器无法找到或不知道heapster正在运行.
我打开了一张票,但似乎没有回复

我设置的东西.

我有以下代码将我的所有用户从multichoice字段放入列表
USERS = []
for user in User.objects.filter(groups__name='accountexec'):
USERS.append((user.id,user))
我需要使用Log.objects.filter()来获取USERS列表中用户=的所有日志
我在尝试提取python中的所有电子邮件标题时遇到了一些问题.我知道如何获得我正在寻找的那些,但我想保存所有的标题,我不知道该怎么做.
我将它加载到电子邮件对象中
import email
f = open(kwargs['opt_emailfile'])
msg = email.message_from_file(f)
f.close()
所以我可以得到
msg['To']
msg['From']
但我想要所有标题
解
这就是我在答案中所做的
f = open(kwargs['opt_emailfile'])
msg = email.message_from_file(f)
f.close()
parser = email.parser.HeaderParser()
headers = parser.parsestr(msg.as_string())
for h in headers.items():
print h
我有以下型号
class Command(models.Model):
server = models.ForeignKey(Server)
user_login = models.CharField(max_length=100)
user_run = models.CharField(max_length=100)
host = models.CharField(max_length=100)
ip = models.CharField(max_length=100)
session = models.CharField(max_length=100)
command = models.TextField()
ts = models.DateTimeField(auto_now_add=True)
version = models.CharField(max_length=100)
type = models.CharField(max_length=100)
我有以下搜索查询
cmds = Command.objects.filter(Q(user_login__contains=form.cleaned_data['loguser']),
Q(user_run__contains=form.cleaned_data['runuser']),
Q(host__contains=form.cleaned_data['loghost']),
Q(command__contains=form.cleaned_data['command']),
Q(server__contains=form.cleaned_data['host']),
Q(session__contains=form.cleaned_data['session'])) \
.order_by('-id')[:100]
我需要通过以下字符串搜索server.host
如果我尝试添加以下内容,则会收到错误消息
Q(server__contains=form.cleaned_data['host']),
Exception Type: TypeError
Exception Value:
Related Field has invalid lookup: contains
Exception Location: /usr/lib/python2.5/site-packages/django/db/models/fields/related.py in get_db_prep_lookup, line 156
form.cleaned_data ['host']将包含主机名的文本字符串.
