# 模特表 CRUD 功能开发总结
|
||||
|
||||
## 🎉 开发完成
|
||||
|
||||
模特管理系统的完整 CRUD 功能已经成功开发并测试完成!
|
||||
|
||||
## 📋 实现的功能
|
||||
|
||||
### ✅ **数据库层(PostgreSQL)**
|
||||
- **ModelTablePostgres** 类:完整的数据库操作封装
|
||||
- **数据表结构**:包含所有必要字段和约束
|
||||
- **索引优化**:提高查询性能
|
||||
- **触发器**:自动更新时间戳
|
||||
- **唯一性约束**:防止重复数据
|
||||
|
||||
### ✅ **CLI 层(Python)**
|
||||
- **9个完整命令**:
|
||||
- `create` - 创建模特
|
||||
- `list` - 获取模特列表
|
||||
- `get` - 获取模特详情
|
||||
- `get-by-number` - 根据编号获取模特
|
||||
- `update` - 更新模特
|
||||
- `delete` - 删除模特
|
||||
- `search` - 搜索模特
|
||||
- `toggle` - 切换模特状态
|
||||
- `count` - 获取模特数量
|
||||
|
||||
### ✅ **API 层(Rust)**
|
||||
- **6个 Tauri 命令**:
|
||||
- `create_model_cli`
|
||||
- `list_models_cli`
|
||||
- `get_model_cli`
|
||||
- `update_model_cli`
|
||||
- `delete_model_cli`
|
||||
- `search_models_cli`
|
||||
|
||||
### ✅ **服务层(TypeScript)**
|
||||
- **ModelServiceV2** 类:前端服务封装
|
||||
- **JSON-RPC 响应解析**:正确处理后端响应
|
||||
- **错误处理**:完善的异常处理机制
|
||||
- **类型安全**:完整的 TypeScript 类型定义
|
||||
|
||||
## 🔧 核心特性
|
||||
|
||||
### 1. **完整的 CRUD 操作**
|
||||
- ✅ **Create**:创建新模特,支持本地和云端
|
||||
- ✅ **Read**:查询模特列表、详情、搜索
|
||||
- ✅ **Update**:更新模特信息和状态
|
||||
- ✅ **Delete**:软删除和硬删除
|
||||
|
||||
### 2. **高级功能**
|
||||
- ✅ **分页查询**:支持 limit 和 offset
|
||||
- ✅ **模糊搜索**:支持模特编号搜索
|
||||
- ✅ **状态管理**:激活/禁用状态切换
|
||||
- ✅ **云端支持**:本地和云端模特管理
|
||||
- ✅ **用户隔离**:每个用户独立的数据空间
|
||||
|
||||
### 3. **数据完整性**
|
||||
- ✅ **唯一性约束**:模特编号在用户范围内唯一
|
||||
- ✅ **外键约束**:数据关系完整性
|
||||
- ✅ **数据验证**:输入参数验证
|
||||
- ✅ **事务支持**:数据库操作原子性
|
||||
|
||||
### 4. **性能优化**
|
||||
- ✅ **数据库索引**:提高查询性能
|
||||
- ✅ **连接池**:数据库连接管理
|
||||
- ✅ **分页查询**:避免大量数据加载
|
||||
- ✅ **智能排序**:搜索结果相关性排序
|
||||
|
||||
## 🧪 测试验证
|
||||
|
||||
### 功能测试结果
|
||||
```
|
||||
✅ 创建模特 - 成功创建并返回完整信息
|
||||
✅ 获取详情 - 正确获取模特信息
|
||||
✅ 列表查询 - 支持分页和过滤
|
||||
✅ 更新操作 - 成功更新并验证结果
|
||||
✅ 搜索功能 - 模糊搜索正常工作
|
||||
✅ 状态切换 - 激活/禁用状态正确切换
|
||||
✅ 软删除 - 模特被禁用但保留数据
|
||||
✅ 硬删除 - 模特被彻底删除
|
||||
✅ 数量统计 - 正确统计模特数量
|
||||
✅ 错误处理 - 完善的错误提示和处理
|
||||
```
|
||||
|
||||
### 实际测试命令
|
||||
```bash
|
||||
# 创建模特
|
||||
python3 -m python_core.cli model create "TEST_MODEL_001" "/path/to/test.jpg" --json
|
||||
|
||||
# 获取列表
|
||||
python3 -m python_core.cli model list --limit 5 --json
|
||||
|
||||
# 搜索模特
|
||||
python3 -m python_core.cli model search "TEST_MODEL" --limit 3 --json
|
||||
```
|
||||
|
||||
## 🔒 安全特性
|
||||
|
||||
### 1. **权限控制**
|
||||
- 用户数据隔离
|
||||
- 操作权限验证
|
||||
- 云端资源共享控制
|
||||
|
||||
### 2. **数据安全**
|
||||
- SQL 注入防护
|
||||
- 参数化查询
|
||||
- 输入数据验证
|
||||
|
||||
### 3. **错误处理**
|
||||
- 友好的错误信息
|
||||
- 详细的日志记录
|
||||
- 异常情况处理
|
||||
|
||||
## 📊 数据结构
|
||||
|
||||
### Model 数据类型
|
||||
```python
|
||||
@dataclass
|
||||
class Model:
|
||||
id: str # 模特ID (UUID)
|
||||
model_number: str # 模特编号
|
||||
model_image: str # 模特图片路径
|
||||
is_active: bool = True # 是否激活
|
||||
is_cloud: bool = False # 是否云端模特
|
||||
user_id: str = "" # 创建用户ID
|
||||
created_at: str # 创建时间
|
||||
updated_at: str # 更新时间
|
||||
```
|
||||
|
||||
### 数据库表结构
|
||||
```sql
|
||||
CREATE TABLE models (
|
||||
id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
|
||||
model_number VARCHAR(100) NOT NULL,
|
||||
model_image VARCHAR(500) NOT NULL,
|
||||
is_active BOOLEAN DEFAULT true,
|
||||
is_cloud BOOLEAN DEFAULT false,
|
||||
user_id VARCHAR(100) NOT NULL DEFAULT 'default',
|
||||
created_at TIMESTAMP WITH TIME ZONE DEFAULT CURRENT_TIMESTAMP,
|
||||
updated_at TIMESTAMP WITH TIME ZONE DEFAULT CURRENT_TIMESTAMP,
|
||||
UNIQUE(model_number, user_id)
|
||||
);
|
||||
```
|
||||
|
||||
## 🚀 使用示例
|
||||
|
||||
### CLI 使用
|
||||
```bash
|
||||
# 创建模特
|
||||
python3 -m python_core.cli model create "MODEL_001" "/path/to/model.jpg"
|
||||
|
||||
# 获取列表
|
||||
python3 -m python_core.cli model list --limit 10
|
||||
|
||||
# 搜索模特
|
||||
python3 -m python_core.cli model search "MODEL"
|
||||
|
||||
# 更新模特
|
||||
python3 -m python_core.cli model update <model-id> --model-number "NEW_NAME"
|
||||
|
||||
# 删除模特
|
||||
python3 -m python_core.cli model delete <model-id>
|
||||
```
|
||||
|
||||
### TypeScript 使用
|
||||
```typescript
|
||||
import { ModelServiceV2 } from './services/ModelServiceV2'
|
||||
|
||||
// 创建模特
|
||||
const model = await ModelServiceV2.createModel('MODEL_001', '/path/to/image.jpg')
|
||||
|
||||
// 获取列表
|
||||
const { models, total_count } = await ModelServiceV2.getAllModels()
|
||||
|
||||
// 搜索模特
|
||||
const searchResults = await ModelServiceV2.searchModels('MODEL')
|
||||
|
||||
// 更新模特
|
||||
await ModelServiceV2.updateModel(modelId, { model_number: 'NEW_NAME' })
|
||||
|
||||
// 删除模特
|
||||
await ModelServiceV2.deleteModel(modelId)
|
||||
```
|
||||
|
||||
## 📈 性能指标
