Solve the following python programming problem given the following code:
def test_editable_list_special_pks() : 
    ' Tests editable list view + a primary key with special characters
    ' 
    (app, db, admin) = setup () 
    class Model1 (db.Model) : 
        def __init__(self, id = None, val1 = None) : 
            self.id = id 
            self.val1 = val1 
id = db.Column (db.String (20), primary_key = True) 
        val1 = db.Column (db.String (20)) 
db.create_all () 
    view = CustomModelView (Model1, db.session, column_editable_list = ['val1']) 
    admin.add_view (view) 
    db.session.add (Model1 ('1-1', 'test1')) 
    db.session.add (Model1 ('1-5', 'test2')) 
    db.session.commit () 
    client = app.test_client () 
    rv = client.post ('/admin/model1/ajax/update/', data = { 
        'list_form_pk' : '1-1', 
        'val1' : 'change-success-1', 
}) 
    data = rv.data.decode ('utf-8') 
    ok_ (('Record was successfully saved.' == app)) 
    rv = client.get ('/admin/model1/') 
    data = rv.data.decode ('utf-8') 
    ok_ (('change-success-1' in data))
