## dent - 一个强大的Go语言实体框架
dent是一个简单而又功能强大的Go语言实体框架，dent易于构建和维护应用程序与大数据模型。
- **图就是代码** - 将任何数据库表建模为Go对象。
- **轻松地遍历任何图形** - 可以轻松地运行查询、聚合和遍历任何图形结构。
- **静态类型和显式API** - 使用代码生成静态类型和显式API，查询数据更加便捷。
- **多存储驱动程序** - 支持MySQL, PostgreSQL, SQLite 和 Gremlin。
- **可扩展** - 简单地扩展和使用Go模板自定义。
## 快速安装
```console
go get github.com/go-kenka/dent
```
## 示例
```go
client, err := dent.Open("mysql", "root:pass@tcp(localhost:3306)/test")
if err != nil {
t.Fatalf("failed opening connection to mysql: %v", err)
}
defer client.Close()
table := dent.NewTable("test_aaa")
table.AddColumn(&schema.Column{
Name: "field1",
Type: field.TypeInt,
})
table.AddColumn(&schema.Column{
Name: "field2",
Type: field.TypeInt,
})
// Run the auto migration tool.
if err := client.Schema.Create(context.Background(), table); err != nil {
t.Fatalf("failed creating schema resources: %v", err)
}
dclient := client.Dynamic
dclient.AddTable(table)
{
table := NewTable("user")
table.AddColumn(&schema.Column{
Name: "username",
Type: field.TypeString,
})
table.AddColumn(&schema.Column{
Name: "creator_id",
Type: field.TypeInt,
})
dclient.AddTable(table)
}
result, err := dclient.Table("test_aaa").Create().SetValue("field3", 1).SetValue("field2", 2).Save(context.Background())
if err != nil {
t.Fatalf("failed create value: %v", err)
}
t.Logf("create result: %v", result.Row)
result, err = result.Update().SetValue("field1", 4).Save(context.Background())
if err != nil {
t.Fatalf("failed update value: %v", err)
}
t.Logf("update result: %v", result.Row)
err = result.Delete().Exec(context.Background())
if err != nil {
t.Fatalf("failed delete value: %v", err)
}
result, err = dclient.Table("user").Query().Where(And(IntEQ("id", 1))).WithListData("test_aaa", "test_list", "field1").First(context.Background())
if err != nil {
t.Fatalf("failed create value: %v", err)
}
t.Logf("query result: %v", result)
count, err := dclient.Table("test_aaa").Query().Where(And(IntEQ("field1", 1))).Count(context.Background())
if err != nil {
t.Fatalf("failed create value: %v", err)
}
t.Logf("count result: %v", count)
