我有一個創建對象的項目，我想使用uuids鍵入對象。當我在manage.py中使用簡單的Django測試服務器運行此項目時，一切都很好。然而我正在嘗試部署到heroku，所以我已經建立了一個virtualenv與一個gunicorn服務器，打破了我的代碼。我已將錯誤追溯到由於某種原因，與此服務器一起運行時，我的UploadedFile對象始終具有空白的訪問鏈接。在virtualenv中將Django項目切換到gunicorn服務器時出錯
這裏是我的models.py代碼：
from django.db import models
import uuid
import datetime
# UUID field will be used to key file upload objects
class UUIDField(models.CharField) :
def __init__(self, *args, **kwargs):
kwargs['max_length'] = kwargs.get('max_length', 64)
kwargs['blank'] = True
models.CharField.__init__(self, *args, **kwargs)
class UploadedFile(models.Model):
#accessLink = UUIDField(primary_key=True, editable=False)
accessLink = models.CharField(primary_key=True, max_length=64)
uploadTime = models.DateTimeField(default=datetime.datetime.now)
filename = models.CharField(max_length=200)
def __init__(self, *args, **kwargs):
super(UploadedFile, self).__init__(*args, **kwargs)
if self.accessLink is '':
self.accessLink = str(uuid.uuid4())
def __unicode__(self):
return filename
這裏是包含在views.py我的指數代碼：
from django.http import HttpResponse # Just for lulz
from django.shortcuts import render
from django.core.context_processors import csrf
from django.shortcuts import render_to_response
from django.template import Template, Context
from smartfile import BasicClient
from filemapper.models import UploadedFile
def index(request):
if request.method == 'POST':
c = {}
c.update(csrf(request))
authKey = 'ggcCEFzGBcJYAQSHNf7AnF8r7c03cB'
authPassword = 'CJlxZHCocieiPOKuhI6GdGOwwTMr2i'
api = BasicClient(authKey, authPassword)
for f in request.FILES.values():
# Create our record of the file
u = UploadedFile(filename=f.name)
u.save()
# Create a directory on smartfile
api.post('/path/oper/mkdir/', path=u.accessLink)
# Upload the file to s
api.post('/path/data/' + u.accessLink, file=f.file, name=u.filename)
# This page should display how to access the uploade
return generate(request, u.accessLink)
else:
return HttpResponse('File not found')
else:
return render(request, 'filemapper/index.html')
的代碼失敗，當我嘗試發佈一個文件添加到索引，因爲u.accessLink不是正確形成的UUID，它是一個空白字符串。
