def construct_models(metadata):
    if not metadata.tables:
        generate_tables(metadata)
    tables = metadata.tables
    models = [model for model in get_all_django_models() if not model._meta.proxy]

    sa_models_by_django_models = {}

    for model in models:

        table_name = (
            metadata.schema + '.' + model._meta.db_table
            if metadata.schema else model._meta.db_table
        )
        mixin = getattr(model, 'aldjemy_mixin', None)
        bases = (mixin, BaseSQLAModel) if mixin else (BaseSQLAModel, )
        table = tables[table_name]
