问题是,循环第二次的时候, 没有数据~
applist = self.collect.find(query, sort=[('weight', DESCENDING)])
self.render(
template_name,
cates=applist,
)
print type(applist)
print applist
<class 'pymongo.cursor.Cursor'>
<pymongo.cursor.Cursor object at 0x7f6a45215d10>
applist = self.collect.find(query, sort=[('weight', DESCENDING)])
self.render(
template_name,
cates=list(applist),
)
print type(applist)
print applist
<type 'list'>

将cursor 对象转换为list类型,解决了这个问题
