Question

我尝试生成一个进程，该进程开始对我的views.crawl中的某些网站进行爬网，这是ajax响应。但是我收到一个AppRegistryNotReady异常：“提高AppRegistryNotReady（“尚未加载应用程序。”）“。我不知道该怎么解决。

这是我的视图文件：

from django.shortcuts import render
from .models import WebPath,FilePath
from django.http import JsonResponse
...
def main(url):
    weburl=WebPath(url,None)
    weburl.save()
    while(WebPath.objects.filter(path=None)):
        starturl()
    downloadfile()

# Create your views here.
def start(request):
    return render(request,'start.html')

@csrf_exempt
def crawl(request):
    global process
    if request.POST['status']=='ok':
        process=multiprocessing.Process(target=main,args=[request.POST['url']])
        process.start()
        print(process.pid)
        return JsonResponse(['ok'],safe=False)
    else:
        process.terminate()
        return JsonResponse(['ok'],safe=False)

例外是：

Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "F:\Anaconda\Anaconda\lib\multiprocessing\spawn.py", line 105, in spawn_main
    exitcode = _main(fd)
  File "F:\Anaconda\Anaconda\lib\multiprocessing\spawn.py", line 115, in _main
    self = reduction.pickle.load(from_parent)
  File "E:\python\django\crawltsinghua\crawl\views.py", line 2, in <module>
    from .models import WebPath,FilePath
  File "E:\python\django\crawltsinghua\crawl\models.py", line 4, in <module>
    class WebPath(models.Model):
  File "F:\Anaconda\Anaconda\lib\site-packages\django\db\models\base.py", line 87, in __new__
    app_config = apps.get_containing_app_config(module)
  File "F:\Anaconda\Anaconda\lib\site-packages\django\apps\registry.py", line 249, in get_containing_app_config
    self.check_apps_ready()
  File "F:\Anaconda\Anaconda\lib\site-packages\django\apps\registry.py", line 132, in check_apps_ready
    raise AppRegistryNotReady("Apps aren't loaded yet.")
django.core.exceptions.AppRegistryNotReady: Apps aren't loaded yet.

引发AppRegistryNotReady（“尚未加载应用程序。”）
