||||
#### 根据定义好的api文件生成Dart代码
|
||||
`goctl api dart -api user/user.api -dir ./src`
|
||||
|
||||
## 根据定义好的简单go文件生成mongo代码文件(仅限golang使用)
|
||||
`goctl model mongo -src {{yourDir}}/xiao/service/xhb/user/model/usermodel.go -cache yes`
|
||||
|
||||
-src需要提供简单的usermodel.go文件，里面只需要提供一个结构体即可
|
||||
-cache 控制是否需要缓存 yes=需要 no=不需要
|
||||
src 示例代码如下
|
||||
```
|
||||
package model
|
||||
|
||||
type User struct {
|
||||
Name string `o:"find,get,set" c:"姓名"`
|
||||
Age int `o:"find,get,set" c:"年纪"`
|
||||
School string `c:"学校"`
|
||||
}
|
||||
|
||||
```
|
||||
结构体中不需要提供Id,CreateTime,UpdateTime三个字段，会自动生成
|
||||
结构体中每个tag有两个可选标签 c 和 o
|
||||
c是改字段的注释
|
||||
o是改字段需要生产的操作函数 可以取得get,find,set 分别表示生成返回单个对象的查询方法，返回多个对象的查询方法，设置该字段方法
|
||||
生成的目标文件会覆盖该简单go文件
|
||||
|
||||
## goctl rpc生成
|
||||
|
||||
命令 `goctl rpc proto -proto ${proto} -service ${serviceName} -project ${projectName} -dir ${directory} -shared ${shared}`
|
||||
如： `goctl rpc proto -proto test.proto -service test -project xjy -dir .`
|
||||
|
||||
参数说明：
|
||||
|
||||
- ${proto}: proto文件
|
||||
- ${serviceName}: rpc服务名称
|
||||
- ${projectName}: 所属项目，如xjy,xhb,crm,hera，具体查看help，主要为了根据不同项目服务往redis注册key，可选
|
||||
- ${directory}: 输出目录
|
||||
- ${shared}: shared文件生成目录，可选，默认为${pwd}/shared
|
||||
|
||||
生成目录结构示例：
|
||||
|
||||
``` go
|
||||
.

# Goctl Model
|
||||
|
||||
<h2>前言</h2>
|
||||
在当前Sql代码生成工具是基于sqlc生成的逻辑。
|
||||
goctl model 为go-zero下的工具模块中的组件之一，目前支持识别mysql ddl进行model层代码生成，通过命令行或者idea插件（即将支持）可以有选择地生成带redis cache或者不带redis cache的代码逻辑。
|
||||
|
||||
<h2>关键字</h2>
|
||||
# 快速开始
|
||||
|
||||
+ 查询类型(前暂不支持同一字段多种类型混合生成，如按照campus_id查询单结果又查询All或者Limit)
|
||||
- 单结果查询
|
||||
- FindOne(主键特有)
|
||||
- FindOneByXxx
|
||||
- 多结果查询
|
||||
- FindAllByXxx
|
||||
- FindLimitByXxx
|
||||
- withCache
|
||||
- withoutCache
|
||||
```
|
||||
$ goctl model -src ./sql/user.sql -dir ./model -c true
|
||||
```
|
||||
|
||||
<h2>准备工作</h2>
|
||||
详情用法请参考[example](https://github.com/tal-tech/go-zero/tools/goctl/model/sql/example)
|
||||
|
||||
- table
|
||||
执行上述命令后即可快速生成CURD代码。
|
||||
|
||||
```
|
||||
CREATE TABLE `user_info` (
|
||||
`id` bigint(20) NOT NULL COMMENT '主键',
|
||||
`campus_id` bigint(20) DEFAULT NULL COMMENT '整校id',
|
||||
`name` varchar(255) DEFAULT NULL COMMENT '用户姓名',
|
||||
`id_number` varchar(255) DEFAULT NULL COMMENT '身份证',
|
||||
`age` int(10) DEFAULT NULL COMMENT '年龄',
|
||||
`gender` tinyint(1) DEFAULT NULL COMMENT '性别，0-男，1-女，2-不限',
|
||||
`mobile` varchar(20) DEFAULT NULL COMMENT '手机号',
|
||||
`create_time` timestamp NULL DEFAULT CURRENT_TIMESTAMP COMMENT '创建时间',
|
||||
`update_time` timestamp NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP COMMENT '更新时间',
|
||||
PRIMARY KEY (`id`)
|
||||
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_0900_ai_ci;
|
||||
```
|
||||
```
|
||||
model
|
||||
│ ├── error.go
|
||||
│ └── usermodel.go
|
||||
```
|
||||
|
||||
<h2>imports生成</h2>
|
||||
imports代码生成对应model中包的引入管理，仅使用于晓黑板项目中（非相对路径动态生成），目前受`withCache`参数的影响，除此之外其实为固定代码。
|
||||
> 注意：这里的目录结构中有usercoursemodel.go目录，在example中我为了体现带cache与不带cache代码的区别，因此将sql文件分别使用了独立的sql文件(user.sql&course.sql)，在实际项目开发中你可以将ddl建表语句放在一个sql文件中，`goctl model`会自动解析并分割，最终按照每个ddl建表语句为单位生成独立的go文件。

```
|
||||
|
||||
<h2>vars生成</h2>
|
||||
|
||||
vars部分对应model中var声明的包含的代码块,由`table`名和`withCache`来决定其中的代码生成内容，`withCache`决定是否要生成缓存key变量的声明。
|
||||
|
||||
- withCache
|
||||
我们默认用户在建表时会创建createTime、updateTime字段(忽略大小写、下划线命名风格)且默认值均为`CURRENT_TIMESTAMP`，而updateTime支持`ON UPDATE CURRENT_TIMESTAMP`，对于这两个字段生成`insert`、`update`时会被移除，不在赋值范畴内，当然，如果你不需要这两个字段那也无大碍。
|
||||
* 带缓存模式
|
||||
|
||||
```
|
||||
var (
|
||||
UserInfoFieldNames = builderx.FieldNames(&UserInfo{})
|
||||
UserInfoRows = strings.Join(UserInfoFieldNames, ",")
|
||||
UserInfoRowsExpectAutoSet = strings.Join(stringx.Remove(UserInfoFieldNames, "id", "create_time", "update_time"), ",")
|
||||
UserInfoRowsWithPlaceHolder = strings.Join(stringx.Remove(UserInfoFieldNames, "id", "create_time", "update_time"), "=?,") + "=?"
|
||||
|
||||
cacheUserInfoIdPrefix = "cache#userInfo#id#"
|
||||
cacheUserInfoCampusIdPrefix = "cache#userInfo#campusId#"
|
||||
cacheUserInfoNamePrefix = "cache#userInfo#name#"
|
||||
cacheUserInfoMobilePrefix = "cache#userInfo#mobile#"
|
||||
)
|
||||
$ goctl model -src {filename} -dir {dir} -cache true
|
||||
```
|
||||
|
||||
目前仅支持redis缓存，如果选择带缓存模式，即生成的`FindOne(ByXxx)`&`Delete`代码会生成带缓存逻辑的代码，目前仅支持单索引字段（除全文索引外），对于联合索引我们默认认为不需要带缓存，且不属于通用型代码，因此没有放在代码生成行列，如example中user表中的`id`、`name`、`mobile`字段均属于单字段索引。
|
||||
|
||||
- withoutCache
|
||||
* 不带缓存模式
|
||||
|
||||
```
|
||||
$ goctl model -src {filename} -dir {dir}
|
||||
```
|
||||
or
|
||||
```
|
||||
$ goctl model -src {filename} -dir {dir} -cache false
|
||||
```
|
||||
生成代码仅基本的CURD结构。
|
||||
|
||||
```
|
||||
var (
|
||||
UserInfoFieldNames = builderx.FieldNames(&UserInfo{})
|
||||
UserInfoRows = strings.Join(UserInfoFieldNames, ",")
|
||||
UserInfoRowsExpectAutoSet = strings.Join(stringx.Remove(UserInfoFieldNames, "id", "create_time", "update_time"), ",")
|

# 缓存
|
||||
|
||||
<h2>types生成</h2>
|
||||
对于缓存这一块我选择用一问一答的形式进行罗列。我想这样能够更清晰的描述model中缓存的功能。
|
||||
|
||||
ypes部分对应model中type声明的包含的代码块,由`table`名和`withCache`来决定其中的代码生成内容，`withCache`决定引入sqlc还是sqlx。
|
||||
* 缓存会缓存哪些信息？
|
||||
|
||||
- withCache
|
||||
```
|
||||
type (
|
||||
UserInfoModel struct {
|
||||
conn sqlc.CachedConn
|
||||
table string
|
||||
}
|
||||
对于主键字段缓存，会缓存整个结构体信息，而对于单索引字段（除全文索引）则缓存主键字段值。
|
||||
|
||||
UserInfo struct {
|
||||
Id int64 `db:"id"` // 主键id
|
||||
CampusId int64 `db:"campus_id"` // 整校id
|
||||
Name string `db:"name"` // 用户姓名
|
||||
IdNumber string `db:"id_number"` // 身份证
|
||||
Age int64 `db:"age"` // 年龄
|
||||
Gender int64 `db:"gender"` // 性别，0-男，1-女，2-不限
|
||||
Mobile string `db:"mobile"` // 手机号
|
||||
CreateTime time.Time `db:"create_time"` // 创建时间
|
||||
UpdateTime time.Time `db:"update_time"` // 更新时间
|
||||
}
|
||||
)
|
||||
```
|
||||
* 数据有更新（`update`）操作会清空缓存吗？
|
||||
|
||||
会，但仅清空主键缓存的信息，why？这里就不做详细赘述了。
|
||||
|
||||
- withoutCache
|
||||
```
|
||||
type (
|
||||
UserInfoModel struct {
|
||||
conn sqlx.SqlConn
|
||||
table string
|
||||
}
|
||||
* 为什么不按照单索引字段生成`updateByXxx`和`deleteByXxx`的代码？
|
||||
|
||||
理论上是没任何问题，但是我们认为，对于model层的数据操作均是以整个结构体为单位，包括查询，我不建议只查询某部分字段（不反对），否则我们的缓存就没有意义了。
|
||||
|
||||
UserInfo struct {
|
||||
Id int64 `db:"id"` // 主键id
|
||||
CampusId int64 `db:"campus_id"` // 整校id
|
||||
Name string `db:"name"` // 用户姓名
|
||||
IdNumber string `db:"id_number"` // 身份证
|
||||
Age int64 `db:"age"` // 年龄
|
||||
Gender int64 `db:"gender"` // 性别，0-男，1-女，2-不限
|
||||
Mobile string `db:"mobile"` // 手机号
|
||||
CreateTime time.Time `db:"create_time"` // 创建时间
|
||||
UpdateTime time.Time `db:"update_time"` // 更新时间
|
||||
}
|
||||
)
|
||||
```
|
||||
<h2>New生成</h2>
|
||||
new生成对应model中struct的New函数，受`withCache`影响决定是否要引入cacheRedis
|
||||
* 为什么不支持`findPageLimit`、`findAll`这么模式代码生层？
|
||||
|
||||
目前，我认为除了基本的CURD外，其他的代码均属于<i>业务型</i>代码，这个我觉得开发人员根据业务需要进行编写更好。
|
||||
|
||||
- withCache
|
||||
```
|
||||
func NewUserInfoModel(conn sqlx.SqlConn, c cache.CacheConf, table string) *UserInfoModel {
|
||||
return &UserInfoModel{
|
||||
CachedConn: sqlc.NewConn(conn, c),
|
||||
table: table,
|
||||
}
|
||||
}
|
||||
```
|
||||
- withoutCache
|
||||
```
|
||||
func NewUserInfoModel(conn sqlx.SqlConn, table string) *UserInfoModel {
|
||||
return &UserInfoModel{conn: conn, table: table}
|
||||
}
|
||||
```
|
||||
# QA
|
||||
|
||||
* goctl model支持根据数据库连接后选择表生成代码吗？
|
||||
|
||||
目前暂时不支持，在后面会向这个方向扩展。
|
||||
|
||||
* goctl model除了命令行模式，支持插件模式吗？
|
||||
|
||||
很快支持idea插件。
|
||||
|
||||
|

<h2>FindOne查询生成</h2>
|
||||
FindOne查询代码生成仅对主键有效。如`user_info`中生成的FindOne如下：
|
||||
|
||||
|
||||
- withCache
|
||||
|
||||
```
|
||||
func (m *UserInfoModel) FindOne(id int64) (*UserInfo, error) {
|
||||
idKey := fmt.Sprintf("%s%v", cacheUserInfoIdPrefix, id)
|
||||
var resp UserInfo
|
||||
err := m.QueryRow(&resp, idKey, func(conn sqlx.SqlConn, v interface{}) error {
|
||||
query := `select ` + userInfoRows + ` from ` + m.table + `where id = ? limit 1`
|
||||
return conn.QueryRow(v, query, id)
|
||||
})
|
||||
switch err {
|
||||
case nil:
|
||||
return &resp, nil
|
||||
case sqlc.ErrNotFound:
|
||||
return nil, ErrNotFound
|
||||
default:
|
||||
return nil, err
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
- withoutCache
|
||||
|
||||
```
|
||||
func (m *UserInfoModel) FindOne(id int64) (*UserInfo, error) {
|
||||
|
||||
query := `select ` + userInfoRows + ` from ` + m.table + `where id = ? limit 1`
|
||||
var resp UserInfo
|
||||
err := m.conn.QueryRow(&resp, query, id)
|
||||
switch err {
|
||||
case nil:
|
||||
return &resp, nil
|
||||
case sqlx.ErrNotFound:
|
||||
return nil, ErrNotFound
|
||||
default:
|
||||
return nil, err
|
||||
|
||||
}
|
||||
```
|
||||
|
||||
<h2>FindOneByXxx查询生成</h2>
|
||||
|
||||
FindOneByXxx查询生成可以按照单个字段查询、多个字段以AND关系且表达式符号为`=`的查询（下称：组合查询）,对除主键之外的字段有效，对于单个字段可以用`withCache`来控制是否需要缓存，这里的缓存只缓存主键，并不缓存整个struct，注意：这里有一个隐藏的规则，如果单个字段查询需要cache，那么主键一定有cache；多个字段组成的`组合查询`一律没有缓存处理,<strong><i>且组合查询不能相互嵌套</i></strong>，否则会报`circle query with other fields`错误，下面我们按场景来依次查看对应代码生成后的示例。
|
||||
|
||||
>注：目前暂不支持除equals之外的条件查询。
|
||||
|
||||
+ 单字段查询
|
||||
以name查询为例
|
||||
- withCache
|
||||
```
|
||||
func (m *UserInfoModel) FindOneByName(name string) (*UserInfo, error) {
|
||||
nameKey := fmt.Sprintf("%s%v", cacheUserInfoNamePrefix, name)
|
||||
var id string
|
||||
err := m.GetCache(key, &id)
|
||||
if err != nil {
|
||||
return nil, err
|
||||
}
|
||||
if id != "" {
|
||||
return m.FindOne(id)
|
||||
}
|
||||
var resp UserInfo
|
||||
query := `select ` + userInfoRows + ` from ` + m.table + `where name = ? limit 1`
|
||||
err = m.QueryRowNoCache(&resp, query, name)
|
||||
switch err {
|
||||
case nil:
|
||||
err = m.SetCache(nameKey, resp.Id)
|
||||
if err != nil {
|
||||
logx.Error(err)
|
||||
}
|
||||
return &resp, nil
|
||||
case sqlc.ErrNotFound:
|
||||
return nil, ErrNotFound
|
||||
default:
|
||||
return nil, err
|
||||
}
|
||||
}
|
||||
```
|
||||
- withoutCache
|
||||
|
||||
```
|
||||

}
|
||||
}
|

||||
以`campus_id`和`id_number`查询为例。
|
||||
|
||||
```
|
||||
func (m *UserInfoModel) FindOneByCampusIdAndIdNumber(campusId int64,idNumber string) (*UserInfo, error) {
|
||||
var resp UserInfo
|
||||
query := `select ` + userInfoRows + ` from ` + m.table + `where campus_id = ? AND id_number = ? limit 1`
|
||||
err = m.QueryRowNoCache(&resp, query, campusId, idNumber)
|
||||
// err = m.conn.QueryRows(&resp, query, campusId, idNumber)
|
||||
switch err {
|
||||
case nil:
|
||||
return &resp, nil
|
||||
case sqlx.ErrNotFound:
|
||||
return nil, ErrNotFound
|

return nil, err
|
||||
}
|
||||
}
|
||||
```

<h2>FindAllByXxx生成</h2>
|
||||
FindAllByXxx查询和FindOneByXxx功能相似，只是FindOneByXxx限制了limit等于1，而FindAllByXxx是查询所有,以两个例子来说明

if err != nil {
|
||||
return nil, err
|
||||
}
|
||||
return resp, nil
|
||||
}
|

```
|
||||
- 查询多个组合字段`campus_id`等于某值且`gender`等于某值的所有数据

<h2>Delete生成</h2>

|
||||
## modelctl用途
|
||||
* 根据数据库中表名生成model.go代码,目前支持通过【指定配置文件】和【命令行参数】两种形式来生成
|
||||
|
||||
## modelctl使用说明
|
||||
* modelctl参数说明
|
||||
|
||||
> 生成配置文件模板
|
||||
|
||||
`modelctl model template`
|
||||
|
||||
> 根据指定配置文件生成*model.go,-c参数为配置文件名称
|
||||
|
||||
参考命令：`modelctl -c config.json`
|
||||
|
||||
> 根据命令行生成*model.go
|
||||
|
||||
`modelctl cmd [--address|-a,--schema|-s,--force|-f,--redis|-r]`
|
||||
|
||||
参考命令：`modelctl cmd -a root:123456@127.0.0.1:3306 -s user -f -r `
|
||||
|
||||
`--address|-a` 数据库连接地址，格式：[username]:[password]@[address],参考格式：root:123456@127.0.0.1:3306
|
||||
|
||||
`--schema|-s` 指定数据库名称
|
||||
|
||||
`--force|-f` 是否强制覆盖源文件，默认：false，强制覆盖将导致原或已修改文件丢失
|
||||
|
||||
`--redis|-r` 是否生成redis缓存逻辑代码，默认：false
|
||||
|
||||
详细说明见 `--help|-h`
|
||||
|
||||
* 配置文件模板说明
