在修改历史状态时是否可以订阅某些事件？怎么样？

我搜索谷歌和这个论坛,我找到了这个解决方案

sth=os.path.abspath('/home/artur/Desktop')
sys.path.append(sth)
os.environ['DJANGO_SETTINGS_MODULE'] = 'project_name.settings'

即使我的编辑器提供对import语句的支持,每个想法似乎都可以.当我尝试导入我的模型时,我得到了这个

Traceback (most recent call last):

这是我正在使用的命令:

appcfg.py download_app -A --application= appid

输出:

我的电子邮件/ pw是正确的.任何人都可以帮我翻译这个错误吗？

class Pair(models.Model):
    first = models.ForeignKey(User, related_name='pair_first')
    second = models.ForeignKey(User, related_name='pair_second')

class PairForm(forms.ModelForm):
    class Meta:
        model = Pair
        fields = ('second',)

    def clean(self):
        first = None # how can I get first?
        second = self.cleaned_data.get("second")

        if (first == second):
            raise ValidationError("You can't pair with yourself, silly.")

def pair_create(request):
    if request.method == 'POST':
        pair = Pair()
        pair.first = request.user
        form = PairForm(instance=pair, data=request.POST)
        if form.is_valid():
            form.save();
            return HttpResponseRedirect(reverse('somewhere'))
    else:
        form = PairForm()

    return render_to_response('something.html', {
        'form': form,
    }, context_instance=RequestContext(request))

登录用户想要与另一个用户配对.它们显示为带下拉列表的表单.如果他们自己选择,则提出验证错误.

问题:在PairForm的clean(self) …

我有一个很好的Mac Pro 4核+超线程.是否有任何Intellij设置需要调整才能利用这一点？通过GUI,还是编辑Info.plist文件？

我对使GWT编译/执行更快更感兴趣.(我已经 localWorkers 4设定好了).

谢谢

我怎么能这样做？

我有以下基于asynctask的代码块.我试图通过返回LoadFeed()返回List变量,并且doInBackground的返回类型是String.如果我将doInBackground的返回类型从String更改为List,那么我会收到错误
