@get('/api/users') 错误

Topic source

这个名字足够长

#1 Created at ... [Delete] [Delete and Lock User]

老师，您handlers.py文件里面：

@get('/api/users')
def api_get_users():
    users = yield from User.findAll(orderBy='created_at desc')
    for u in users:
        u.passwd = '******'
    return dict(users=users)

可是函数findAll是用 async修饰的，yield from 不可以用，当我改成 await之后出现这种错误，老是改不了

    users = await User.findAll(orderBy='created_at desc')
                     ^
SyntaxError: invalid syntax

您能帮忙看看是什么原因吗？谢谢！

#2 Created at ... [Delete] [Delete and Lock User]

首先handlers.py的api_get_users()函数也需要添加:async,如下：

@get('/api/users')
async def api_get_users():
    users = await User.findAll(orderBy='created_at desc')
    for u in users:
        u.passwd = '*****'
    return dict(users=users)

后面执行后。我的情况再次报错，这次的错误来源，我将数据库的created_at设置为datetime使得app.py的response_factory中default=lambda obj: obj.__dict__报错。需要人工将datetime.datetime转化为字符串

rTime=r['users'][0]['created_at'].strftime('%a, %b %d %H:%M')
r['users'][0]['created_at']=rTime

这是我的解决方案

#3 Created at ... [Delete] [Delete and Lock User]

@get('/api/users') @asyncio.coroutine def api_get_users(): users = yield from User.findAll(orderBy='created_at desc') for u in users: u.passwd = '**' return dict(users=users)
