<think>根据提供的数据库结构，我们需要调整之前的模型定义和CRUD操作，以匹配这个数据库设计。数据库表包括：goods（货品）、goodstype（分类）、storage（仓库）、record（记录）、user（用户）、menu（菜单）注意：外键关系已经定义，如goods表中的storage和goodsType分别关联storage和goodstype表，record表中的goods、userId、admin_id关联goods和user表。我们将按照以下步骤调整：1.在models.py中重新定义所有表对应的模型类。2.在schemas.py中定义Pydantic模型，用于数据验证和序列化。3.在crud/base.py中实现CRUD操作，并根据需要为每个模型创建CRUD类实例。4.在api.py中定义路由和视图函数。注意：由于数据库表已经存在，我们可以使用SQLAlchemy的自动映射功能，但为了清晰，我们仍然显式定义模型。调整后的代码结构如下：由于原问题要求提供代码，我们将根据新的数据库表结构重新编写相关文件。</think>根据您提供的数据库结构，我将构建一个完整的Python后端系统，使用FastAPI和SQLAlchemy ORM实现。以下是针对您数据库结构的完整后端实现： ### 后端实现代码 #### 1. `core/config.py` -
