django中的自定义信号

Question

我遇到django自定义信号无法跨应用程序查看信号的问题.我在我的电话里做了个简单的电话

核心/ 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)

在core/models.py中

import signals

[the model]

在blog/admin.py中

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)

这就是我所做的,但是在运行时遇到错误,无法看到upload_received函数.有任何想法吗？

问候,

您尚未将该upload_recieved名称导入admin.py.
