InvalidSchema找不到的连接适配器，djang中有错误

Question

我正在尝试http://robobrowser.readthedocs.org/en/latest/readme.html，这是一个基于漂亮的soup和requests库的新python库。我目前正在使用它打开一系列页面，并将响应保存到一个列表中，以便以后进行解析。调试器中的列表如下：

pages =   [<Response [200]>, <Response [200]> ....]

我通过让robobrowser对象遍历一些页面并保存响应来生成此列表：

while pageRight:
    browser.follow_link(pageright[0])
    browser
    page = browser.response
    pages.append(page)
    pageRight= browser.select(".pageright")

上面这一部分似乎运行良好，但是当我尝试：

ag = "myagent"
browser = RoboBrowser(user_agent=ag)

for page in pages:
    browser.open(page.content)
    for listing in browser.select('.listingInfo'): #a list
        pl = getParsedListing(listing)
        listings.append(pl)

在我的django索引文件中，我得到一个错误：

InvalidSchema at /index/

No connection adapters were found for..

回溯：

Traceback:

我做错什么了？
