feat: Add Dynamic REST Controller and Service for PySpringModel

[NFUChen]

Description

This pull request introduces dynamic RESTful API support for PySpringModel entities, significantly simplifying CRUD operations and resource management. By incorporating a PySpringModelRestController and a PySpringModelRestService, the framework now provides an extensible mechanism to handle model-based API endpoints dynamically.

Key Changes

1. Controller:

   • Added PySpringModelRestController, which dynamically registers CRUD routes for all models registered with the framework.
   • Supports standard operations: GET, POST, PUT, and DELETE for single and multiple records.

2. Service:

   • Implemented PySpringModelRestService to encapsulate database operations for PySpringModel entities.
   • Handles logic for fetching, creating, updating, and deleting records.

3. Provider Update:

   • Enhanced PySpringModelProvider to include PySpringModelRestController and PySpringModelRestService as injectable components.

4. Dynamic Routing:

   • Routes are dynamically registered based on the available models, reducing boilerplate code and simplifying API management.

Motivation

The new REST capabilities enhance the framework's usability, allowing developers to quickly expose APIs for their models without repetitive manual configuration. This change aligns with the framework's goal of providing seamless and intuitive integrations.

Example Usage

Once a model is registered with the framework, the REST controller will automatically expose endpoints such as:

• GET /{model_name}/{id}: Fetch a single record by ID.
• POST /{model_name}: Create a new record.
• PUT /{model_name}/{id}: Update an existing record.
• DELETE /{model_name}/{id}: Delete a record by ID.

How to Test

1. Register a PySpringModel entity in the framework.
2. Start the application and access the generated API endpoints via the provided routes.
3. Perform CRUD operations and ensure responses match the expected behavior.

Checklist

• Added PySpringModelRestController for dynamic route registration.
• Implemented PySpringModelRestService for CRUD logic.
• Updated PySpringModelProvider to inject new components.
• Tested the endpoints for a registered model.

Additional Notes

This update sets the foundation for further extensions, such as advanced query support, custom validation, and role-based access control for model APIs.
