Clone sqlalchemy model

clone_model.py

def clone_model(model):
    """Clone an arbitrary sqlalchemy model object without its primary key values."""
    # Ensure the model’s data is loaded before copying.
    model.id

    table = model.__table__
    non_pk_columns = [k for k in table.columns.keys() if k not in table.primary_key]
    data = {c: getattr(model, c) for c in non_pk_columns}
    data.pop('id')
    return data

Its designed to return dict. U can create model in a simple way:
model = Model(**model_dict)

you also don't need to pop('id') if you have the k not in table.primary_key list-comprehension predicate on line 7
