如何在django中为每个用户使用临时数据库

class UserDatabaseRouter:
    def db_for_read(self, model, **hints):
        if model._meta.app_label == 'your_app_label':
            # 获取当前用户的数据库名称
            user_db = get_current_user().database_name
            return user_db
        return None

    def db_for_write(self, model, **hints):
        if model._meta.app_label == 'your_app_label':
            user_db = get_current_user().database_name
            return user_db
        return None

    def allow_relation(self, obj1, obj2, **hints):
        if obj1._meta.app_label == 'your_app_label' or obj2._meta.app_label == 'your_app_label':
            return True
        return None

    def allow_migrate(self, db, app_label, model_name=None, **hints):
        if app_label == 'your_app_label':
            return db == get_current_user().database_name
        return None
