Django tastypie web应用程序中的Django中的ModuleNotFound错误

Question

我对Django很新颖。

当我尝试从api.py文件包含url时，它返回一个错误。

下面是文章的应用程序文件夹

from tastypie.resources import ModelResource 
from tastypie.constants import ALL 
from article.models import Article 


class ArticleResource(ModelResource): 
    class Meta: 
     querySet = Article.objects.all() 
     resource_name = 'article' 

这里api.py文件从文章app文件夹

from django.conf.urls import url 
from article.views import * 
from .api import ArticleResource 
from django.conf.urls import include 

article_resource = ArticleResource() 

urlpatterns = [ 
url(r'^api/',include('article_resource.urls')) 
] 

和错误我回来了urls.py文件是这样的

ModuleNotFoundError: No module named 'article_resource' 

Answer 1

删除包含引号将解决问题

urlpatterns = [ 
url(r'^api/',include(article_resource.urls)) 
] 

注意：Django的include功能使用Python的import_module从字符串导入模块，但在这里，article_resource只在本地范围内都有效。
