所以我刚刚开始将我的旧代码移植到基于类的视图，我仍然是新手。我的问题与 Django mixins 相关，我有一个 mixin，我将在各种类中使用它来验证一些信息。问题是我不知道如何访问它返回的信息而不会出现 500 内部错误。
class CheckTokenMixin(object):
def request_token(self,request):
params = {'username':settings.OAUTH_USERNAME,'password':hashlib.sha256(settings.OAUTH_PASSWORD).hexdigest()}
req = Request(settings.REMOTE_SERVER+'oauth', urllib.urlencode(params))
return json.loads(urlopen(req).read())
def get_valid_token(self):
if datetime.datetime.now() > request.session['access_token'].creation_date + datetime.timedelta(days=1):
temp = self.request_token(request)
tokenobj = AccessToken.objects.all()[:1].get()
tokenobj.access_token = temp['token']
tokenobj.creation_date = datetime.datetime.now()
tokenobj.save()
request.session['access_token'] = tokenobj
return request.session['access_token']
def get_context_data(self, **kwargs):
ctx = super(CheckTokenMixin, self).get_context_data(**kwargs)
ctx['access_token'] = self.get_valid_token()
return ctx

return super(RateAppView, self).dispatch(*args, **kwargs)
def post_ajax(self, request, username):
u = get_object_or_404(User, …因此,当它达到maxBytes大小时,我遇到了Django日志记录的一些问题.基本上当发生这种情况时,文件似乎不会旋转并创建新文件.
有人告诉我,这可能与服务器的写入权限有关,但我不知道如何正确设置,以便django能够在旧的日志文件已满时创建新的日志文件.
我的设置:

我该如何解决这个问题？
所以我试图上传一个没有任何外部插件的文件,但我遇到了一些错误.
<form method="" action="" name='upload_form' id='upload_form' >
{% csrf_token %}
<input type='file' name='file' id='file' />
<input type='button' value='Upload' id='upload'/>
</form>
<script type='text/javascript'>
$(document).ready(function() {
var csrf_token = $('input[name="csrfmiddlewaretoken"]').val();
$('#upload').click(function() {
$.ajax({
csrfmiddlewaretoken: csrf_token,
type: 'POST',
url : 'upload',
enctype: "multipart/form-data",
data : {
'file': $('#file').val()
},
success: function(data) {
console.log(data)
}
})
})
})
</script>
我的服务器:
class ImageUploadView(LoginRequiredMixin, JSONResponseMixin, AjaxResponseMixin, CurrentUserIdMixin, View):
@method_decorator(csrf_protect)
def dispatch(self, *args, **kwargs):
return super(ImageUploadView, self).dispatch(*args, **kwargs)
def post_ajax(self, request, username):
print request.POST.get('file', None)
print request.FILES …我最近向Heroku部署了一个Django应用程序并上传了一些媒体文件,一切似乎都运行良好,直到昨天我再次尝试访问该应用程序并发现它发出了404错误.
任何想法为什么会这样？
