ent 提供了cli 工具，可以方便我们进行schema 以及代码生成，同时目前提供的cli已经够用了
go get github.com/facebookincubator/ent/cmd/entc
entc init User Pet
基于schema 的定义（字段，索引，边，配置）
entc generate ./ent/schema
说明：
生成的代码包含了crud、migrate、entity、client
使用独立的cli以及生成的代码，可能会和我们的框架不兼容 ，处理方法使用go:generate
参考配置：
package ent
?
//go:generate go run github.com/facebookincubator/ent/cmd/entc generate ./schema
generate go code for the schema directory
?
Usage:
entc generate [flags] path
?
Examples:
entc generate ./ent/schema
entc generate github.com/a8m/x
?
Flags:
--header string override codegen header
-h, --help help for generate
--idtype [int string] type of the id field (default int)
--storage strings list of storage drivers to support (default [sql])
--target string target directory for codegen
--template strings external templates to execute
entc 可以做为一个包在我们的项目中使用
package main
?
import (
"log"
?
"github.com/facebookincubator/ent/entc"
"github.com/facebookincubator/ent/entc/gen"
"github.com/facebookincubator/ent/schema/field"
)
?
func main() {
err := entc.Generate("./schema", &gen.Config{
Header: "// Your Custom Header",
IDType: &field.TypeInfo{Type: field.TypeInt},
})
if err != nil {
log.Fatal("running ent codegen:", err)
}
}
entc describe ./ent/schema
