用couchdb-python管理_users中的用户

Question

我试图使用_users从数据库couchdb-python中存储和检索用户。我是couchdb的初学者。

我用couchdb文档couchdb.mapping.Document映射了python类用户，如下所示：

import couchdb.mapping as cmap


class User(cmap.Document):
    name = cmap.TextField()
    password = cmap.TextField()
    type = 'user'
    roles = {}

但这不管用。我得到了doc.type must be user ServerError，所以我声明类型的方式可能不正确。

如何构造要与_users数据库一起使用的类？

Answer 1

在从IRC上的#couchdb频道得到一些提示后，我推出了这个类(这可能比我要求的要多.)

import couchdb.mapping as cmap

class User(cmap.Document):
    """  Class used to map a user document inside the '_users' database to a
    Python object.

    For better understanding check https://wiki.apache.org
        /couchdb/Security_Features_Overview

    Args:
        name: Name of the user
        password: password of the user in plain text
        type: (Must be) 'user'
        roles: Roles for the users

    """

    def __init__(self, **values):
        # For user in the _users database id must be org.couchdb.user:<name>
        # Here we're auto-generating it.
        if 'name' in values:
            _id = 'org.couchdb.user:{}'.format(values['name'])
            cmap.Document.__init__(self, id=_id, **values)

    type = cmap.TextField(default='user')
    name = cmap.TextField()
    password = cmap.TextField()
    roles = cmap.ListField(cmap.TextField())

    @cmap.ViewField.define('users')
    def default(doc):
        if doc['name']:
            yield doc['name'], doc

这应该是可行的：

db = couchdb.server()['_users']
alice = User(name="Alice", password="strongpassword")
alice.store(db)
