inline_models don't work for one-to-many

I’ve not been able to make inline_models forms for one-to-many, and I think it’s linked to this line: https://github.com/flask-admin/flask-admin/blob/master/flask_admin/contrib/sqla/form.py#L561

class Company(Model):
    id = db.Column(db.Integer, primary_key=True)
    address_id = db.Column(db.Integer, db.ForeignKey('address.id'))
    address = db.relationship('Address', backref='companies')

class Address(Model):
    id = db.Column(db.Integer, primary_key=True)

class CompanyModelView(ModelView):
    inline_models = (Address, )

That gives me the following exception: Exception: Cannot find reverse relation for model <class 'app.models.address.Address'>

Wondering if I’m missing something, or if this is per design ? It seems possible to change the key resolution method there to support the one-to-many.

models.py

class User(db.Model):
    id          = db.Column(db.Integer, primary_key=True, autoincrement=True)

class UserProfile(db.Model):
    user_id     = db.Column(db.Integer, db.ForeignKey(User.id), nullable=False)
    user        = db.relationship(User, backref=db.backref("profiles", lazy="dynamic"))

views.py

from flask_admin.model.fields import InlineModelFormField, InlineFormField, InlineFieldList
from wtforms.utils import unset_value

class InlineFieldListA(InlineFieldList):
    def process(self, formdata, data=unset_value):
        res = super().process(formdata, [data])  # hack
        return res

class UserAdmin(base.ModelView):
    model_class = User


class UserProfileAdmin(base.ModelView):
    model_class = UserProfile

    def scaffold_form(self):
       # use native modelview
        form = super().scaffold_form()
        ua = UserAdmin(db.session)
        user_form = ua.get_form()
        form.user = InlineFieldListA(InlineFormField(user_form))
        return form

Wubba lubba dub dub!

A quick workaround is to apply the inline model to the inverse relationship. For example in OPs original example instead of applying the inline mode to CompanyModelView you would do:

class Address ModelView(ModelView):
    inline_models = (Company, )

While this isn’t exactly what was asked for, it does allow you to achieve the goal of creating both models on one webpage.
