【问题描述】：

我对 Django 很陌生。

当我尝试包含 api.py 文件中的 url 时，它会返回一个错误。

这里是文章应用文件夹中的 api.py 文件

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'

这里是文章应用文件夹中的 urls.py 文件

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'))
]

我得到的错误是这个

【解决方案1】：

从include中删除引号将解决问题

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

注意：Django include 函数使用 python 的 import_module 从字符串导入模块，但在这里，article_resource 仅在您的本地范围内可用。
