我是python中的新手.今天当我写一些搜索功能时遇到错误.我使用sqlalchemy orm来做到这一点,在我的函数中,我输入一个中文单词作为关键词.html页面给我一个UnicodeEncodeError在/ user/search:'latin-1'编解码器不能编码位置0-1中的字符:序数不在范围内(256).我的代码是这样的:

def user_search(request):
    name = request.GET.get('name').strip()
    user_list = list()

    if name:
        user_list = User.get_by_name(name)

class User(object):
    @classmethod
    def get_by_name(cls, name):
        return DBSession.query(cls).filter(cls.name==name)

Traceback在这里:

当我使用alembic来控制项目数据库的版本时,env.py中的部分代码如下:

# add your model's MetaData object here
# for 'autogenerate' support
# from myapp import mymodel
# target_metadata = mymodel.Base.metadata
from al_test.models import metadata

target_metadata = metadata

当我运行'alembic revision --autogenerate -m"添加用户表"'时,我收到一个错误:文件"alembic/env.py",第18行,来自al_test.models导入元数据ImportError:没有名为al_test.models的模块

那怎么解决这个问题呢？谢谢!
