Solve the following python programming problem given the following code:
def test_ajax_fk_multi() : 
    (app, db, admin) = setup () 
    class Model1 (db.Model) : 
        __tablename__ = 'model1' 
        id = db.Column (db.Integer, primary_key = True) 
        name = db.Column (db.String (20)) 
        def __str__(self) : 
            return self.name 
table = db.Table ('m2m', db.Model.metadata, db.Column ('model1_id', db.Integer, db.ForeignKey ('model1.id')), db.Column ('model2_id', db.Integer, db.ForeignKey ('model2.id'))) 
    class Model2 (db.Model) : 
        __tablename__ = 'model2' 
        id = db.Column (db.Integer, primary_key = True) 
        name = db.Column (db.String (20)) 
        model1_id = db.Column (db.Integer (), db.ForeignKey (Model1.id)) 
        model1 = db.relationship (Model1, backref = 'models2', secondary = table) 
db.create_all () 
    view = CustomModelView (Model2, db.session, url = 'view', form_ajax_refs = { 
        'model1' : { 
            'fields' : ['name'], 
}, 
}) 
    admin.add_view (view) 
    ok_ (('model1' in view._form_ajax_refs)) 
    model = Model1 (name = 'first') 
    db.session.add_all ([form, Model1 (name = 'foo')]) 
    db.session.commit () 
    form = view.create_form () 
    eq_ (form.model1.__class__.__name__, 'AjaxSelectMultipleField') 
    with app.test_request_context ('/admin/view/') : 
        ok_ (('data-json="[]"' in form.model1 ())) 
        form.model1.data = [model] 
        ok_ (('data-json="[[1, &quot;first&quot;]]"' in form.model1 ())) 
client = app.test_client () 
    client.post ('/admin/view/new/', data = { 
        'model1' : as_unicode (model.id), 
}) 
    mdl = db.session.query (Model2).first () 
    ok_ ((mdl is not None)) 
    ok_ ((mdl.model1 is not None)) 
    eq_ (len (mdl.model1), 1) 

    
    

    Fix the buggy line: db.session.add_all ([form, Model1 (name = 'foo')])
assistant
#Here is Python code to fix the buggy line: db.

db.session.add_all ([model, Model1 (name = 'foo')])
