Flask Admin doesn't show all fields - flask-admin

Question

I have model like this:
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
I have ModelView:
class UserAdmin(sqlamodel.ModelView):
searchable_columns = ('username', 'email')
excluded_list_columns = ['password']
list_columns = ('username', 'email')
form_columns = ('username', 'email', 'password')
But no matter what i do, flask admin didn't show password field when i'm editing user info. Is there any way ? Even just to edit hash code.

Answer 1

Reason why it did not work - Flask-Admin was not able to figure out what to do with SynonymProperty, so it failed to generate form field.
There's a way you can have it working right now:
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
I pushed simple fix which adds support for the SynonymProperty, so it will work even without form customization. Unfortunately, I'm in process of adding MongoDB backend, so I won't be able to release new version any time soon.
Just in case, SynonymProperty was superseded by hybrid properties in SQLAlchemy 0.7 and onward, which should be supported by the Flask-Admin.

Much better:
from wtforms.fields import PasswordField
class UserAdmin(sqlamodel.ModelView):
searchable_columns = ('username', 'email')
excluded_list_columns = ['password']
form_overrides = dict(password=PasswordField)
