|
||
|
||
## 1. 表定义
|
||
|
||
**表名**：`tx_hardware`
|
||
|
||
**描述**：TX硬件版本维度表，存储所有硬件版本号
|
||
|

|
||
## 2. 字段定义
|
||
|
||
| 列名 | 类型 | 约束 | 说明 |
|
||
|------|------|------|------|
|
||
| id | UUID | PK, NOT NULL | 主键，自动生成 |
|
||
| version | VARCHAR(50) | UNIQUE, NOT NULL | 硬件版本号 |
|
||
| is_deleted | BOOLEAN | NOT NULL, DEFAULT FALSE | 软删除标记 |
|
||
| created_at | TIMESTAMP | NOT NULL, DEFAULT NOW() | 创建时间 |
|
||

## 3. EF Core 模型
|
||
|
||
### 实体类
|
||
|
||
```csharp
|
||
// Models/TxHardware.cs
|
||
namespace WCTDataMiner.Models;
|
||
|
||
public class TxHardware
|
||
{
|
||
public Guid Id { get; set; } = Guid.NewGuid();
|
||
public string Version { get; set; } = null!;
|
||
public bool IsDeleted { get; set; } = false;
|
||
public DateTime CreatedAt { get; set; } = DateTime.UtcNow;
|
||
|
||
// Navigation Properties
|
||
public ICollection<TestScenario> TestScenarios { get; set; } = [];
|
||
}
|
||
```
|
||
|
||
### 配置类
|
||
|
||
```csharp
|
||
// Data/Configurations/TxHardwareConfiguration.cs
|
||
using Microsoft.EntityFrameworkCore;
|
||
using Microsoft.EntityFrameworkCore.Metadata.Builders;
|
||
using WCTDataMiner.Models;
|
||
|
||
namespace WCTDataMiner.Data.Configurations;
|
||
|
||
public class TxHardwareConfiguration : IEntityTypeConfiguration<TxHardware>
|
||
{
|
||
public void Configure(EntityTypeBuilder<TxHardware> builder)
|
||
{
|
||
builder.ToTable("tx_hardware");
|
||
|
||
builder.HasKey(e => e.Id);
|
||
builder.Property(e => e.Id).HasColumnName("id");
|
||
|
||
builder.Property(e => e.Version)
|
||
.IsRequired()
|
||
.HasMaxLength(50)
|
||
.HasColumnName("version");
|
||
|
||
builder.Property(e => e.IsDeleted)
|
||
.IsRequired()
|
||
.HasDefaultValue(false)
|
||
.HasColumnName("is_deleted");
|
||
|
||
builder.Property(e => e.CreatedAt)
|
||
.IsRequired()
|
||
.HasDefaultValueSql("NOW()")
|
||
.HasColumnName("created_at");
|
||
|
||
builder.HasIndex(e => e.Version).IsUnique();
|
||
}
|
||
}
|
||
```
|
||
|
||

|
||
|
||
## 4. 使用说明
|
||
|
||
硬件版本在解析文件名时自动创建，无需预置数据：
|
||
|
||
```csharp
|
||
// 获取或创建硬件版本
|
||
public async Task<TxHardware> GetOrCreateAsync(string version)
|
||
{
|
||
var existing = await context.TxHardwares
|
||
.FirstOrDefaultAsync(h => h.Version == version);
|
||
|
||
if (existing != null) return existing;
|
||
|
||
var newHardware = new TxHardware { Version = version };
|
||
context.TxHardwares.Add(newHardware);
|
||
await context.SaveChangesAsync();
|
||
return newHardware;
|
||
}
|
||
``` |
