Form column is not being displayed if it starts with underscore "_"

[princerb]

if I set form_columns to ('name', '_surname'), it only displays name in the form page, leaving other columns that starts with the underscore "_" in its name.

Example:

class MyModelView(ModelView):
    column_list = ('name', '_surname')
    form_columns = ('name', '_surname')

Model would look like this (SQLAlchemy):

class User(Base):
    __tablename__ = 'users'
    id = Column(Integer, primary_key=True)
    name = Column(String(100), nullable=False)
    _surname = Column(String(100), nullable=False)

So, in the form pages (edit, create) of the user, input fields of the columns those start with "_" will not be rendered in html page.

Hope, you found it a new noticable thing!

Could someone please explain this? 🤔

I think this is because the convention is to hide attributes that start with "_" (private). Maybe there is a way to expose it, but best will be to rename it to "surname".

It can't be renamed in some cases, so I think there should be a force command to implement it for certain situations.

Have you tried setting ignore_hidden?

class MyModelView(ModelView):
    ignore_hidden = False

I just tried ignore_hidden, but didn't work, and I guess that setting does not apparently work or has some bugs.
