Django中的自定义信号

Question

我在使用Django的自定义信号时遇到了问题，信号在不同的应用之间无法互相识别。我在我的

core/signals.py

from django.dispatch.dispatcher import Signal
# Signal-emitting code... emits whenever a file upload is received
# ----------------------------------------------------------------

upload_recieved = Signal(providing_args=['data'])


def upload_received_handler(sender, data, **kwargs):
    print 'upload received handler'

print 'connecting signal'
upload_recieved.connect(upload_received_handler)

文件中做了一个简单的调用。

在

core/models.py

import signals

[the model]

和

blog/admin.py

from models import article, category, media 
from django.contrib import admin
from libs.shared.core.tasks import Create_Audit_Record
from libs.shared.core import signals



class ArticleModelAdmin(admin.ModelAdmin):
    def save_model(self, request, obj, form, change):
        upload_recieved.send(sender=self, data='ddd')
        instance = form.save()
        return instance



admin.site.register(article, ArticleModelAdmin)
admin.site.register(category)
admin.site.register(media)

中也是如此。可是我在运行时遇到了错误，无法找到upload_received这个函数。有没有什么想法？

祝好，

你还没有在你的admin.py文件里导入upload_recieved这个名字。
