Flask Admin不显示所有字段

Question

我有这样的模型:

class User(db.Model):
    __tablename__ = 'users'
    __table_args__ = {'mysql_engine' : 'InnoDB', 'mysql_charset' : 'utf8'}
    id = db.Column(db.Integer, primary_key=True)
    username = db.Column(db.String(80), unique=True)
    email = db.Column(db.String(120), unique=True)
    _password = db.Column('password', db.String(80))

    def __init__(self, username = None, email = None, password = None):
        self.username = username
        self.email = email
        self._set_password(password)

    def _set_password(self, password):
        self._password = generate_password_hash(password)

    def _get_password(self):
        return self._password

    def check_password(self, password):
        return check_password_hash(self._password, password)

    password = db.synonym("_password", descriptor=property(_get_password, _set_password))

    def __repr__(self):
        return '<User %r>' % self.username

我有ModelView:

class UserAdmin(sqlamodel.ModelView):
    searchable_columns = ('username', 'email')
    excluded_list_columns = ['password']
    list_columns = ('username', 'email')
    form_columns = ('username', 'email', 'password')

但无论我做什么,当我正在编辑用户信息时,flask admin都没有显示密码字段.有什么办法吗？甚至只是编辑哈希码.

它无效的原因 - Flask-Admin无法弄清楚如何处理SynonymProperty,因此无法生成表单字段.

有一种方法可以让它立即运作:

class UserAdmin(sqlamodel.ModelView):
    searchable_columns = ('username', 'email')
    excluded_list_columns = ['password']
    list_columns = ('username', 'email')
    form_columns = ('username', 'email')

    def scaffold_form(self):
        form_class = super(UserAdmin, self).scaffold_form()
        form_class.password = wtf.TextField('Password')
        return form_class

我推动了简单的修复,它增加了对SynonymProperty的支持,因此即使没有表单自定义它也能工作.不幸的是,我正在添加MongoDB后端,所以我很快就无法发布新版本.

为了以防万一,SynonymProperty被SQLAlchemy 0.7及以后的混合属性所取代,Flask-Admin应该支持它.
