python - 为什么不在所有页面django中导入模型

Question

from models import *


def info(request):
    yasin = "teksaas"
    if check_key(request):
        api = get_api(request)
        user = api.me()
        userid = user.id
        accounts=accounts.objects.filter(twitterid=userid)
        if accounts == 1:
            return render_to_response('twitter_auth/info.html', locals())
        else:

            registeracc=accounts(twitterid=412313,others='Hello im jsaon walker what your problem i cant unt')
            registeracc.save()
            return render_to_response('twitter_auth/info.html', locals()) 
    else:
        return HttpResponseRedirect(reverse('main'))


Error : local variable 'accounts' referenced before assignment

如果我更改此代码它正在工作，但我不想要多个导入模型

def info(request):
    yasin = "teksaas"
    if check_key(request):
                from models import *
        api = get_api(request)
        user = api.me()
        userid = user.id
        accounts=accounts.objects.filter(twitterid=userid)
        if accounts == 1:
            return render_to_response('twitter_auth/info.html', locals())
        else:
            from models import *
            registeracc=accounts(twitterid=412313,others='Hello im jsaon walker what your problem i cant unt')
            registeracc.save()
            return render_to_response('twitter_auth/info.html', locals()) 
    else:
        return HttpResponseRedirect(reverse('main'))

不要像你的类一样命名你的变量

accounts=accounts.objects.filter(twitterid=userid)

尝试修复它，看看是否有帮助

from models import *
def info(request):
    yasin = "teksaas"
    if check_key(request):
        api = get_api(request)
        user = api.me()
        userid = user.id
        acc=accounts.objects.filter(twitterid=userid)
        if acc:
            return render_to_response('twitter_auth/info.html', locals())
        else:

            registeracc=accounts(twitterid=412313,others='Hello im jsaon walker what your problem i cant unt')
            registeracc.save()
            return render_to_response('twitter_auth/info.html', locals()) 
    else:
        return HttpResponseRedirect(reverse('main'))
