基于CI3.0 开发的ORM，操作数据更加简单, 抛弃CI_Model

Github: https://github.com/wugang8068/RealRap

安装方法:

composer require csitc/real-rap dev-master

欢迎大家进行fork, 如果给我一个star, 我会更加努力维护的哦;

ORM有什么好处， 想必各位都大概知道了， ORM可以方便我们查找数据更加便捷，只需要去维护模型之间的关系， 而不需要去处理各种复杂的SQL语句，RealRap彻底抛弃CI_Model, 使用更抽象的\RealRap\Model作为模型父类。 底层的sql查询还是采用CI_DB_query_builder的AR。可以看做是对DB的一层封装吧。 相对于Laravel的Eloquent来说，无需配置Connection,直接复用CI的DB Connection。目前支持单个模型的CRUD，还不支持模型关联等复杂的关系逻辑。后面会慢慢完善这个项目。我是一名PHP小菜，还请各位大神勿喷，缺点还请大家赐教。

以下是英文介绍, 鄙人英文很low ,将就看一下吧;

RealRap

This is a CI ORM, and inspired by laravel eloquent

Retrieve

Example: We need to fetch the user where user_id >= 50 and order by user_id and user_mobile and get the first one

$users = User::all(['*'])->where([
'user_id <=' => 50]
)->order([
'user_id' => 'desc',
'user_mobile' => 'desc'])
->limit(1)->getOne();

The result mybe like this:

{
"id":50,
"user_nick_name":"18386053521",
"user_device_id":"B86E62AC-5FC4-45E3-A3F0-EB4544DB135D",
"user_mobile":"17288",
"user_create_date":"2016-07-10 09:44:54"
}

In the User.php, we can just write like this:

class User extends Model{

protected $table = 'inf_user';

protected $primaryKey = 'user_id';

protected $cast = [
'user_id' => 'integer',
'is_subscribed' => 'bool'
];

protected $hidden = [
'agent_user',
'bank_real_name',
'is_subscribed',
'rebate_already_mentioned',
'rebate_being_mention',
'rebate_unmentioned',
'user_email'
];

protected $attributes = [
'user_id' => 'id',
];

}

Update

$user = User::findWhere([
'user_mobile' => '12381121695'
])->getOne();
if($user){
$user->user_mobile = '134234';
$user->save();
}

Create

$user = new User();
$user->user_nick_name = 'Tom';
$user->save();

Delete

$user = User::findWhere(['user_mobile' => '18600908262'])->getOne();
if($user){
print_r($user->delete() ? 'record delete success' : 'record delete failed');
}else{
print_r('record is not exists');
}

or

User::findWhere(['user_mobile' => '18600908262'])->delete()

Transaction

\RealRap\RealRap::trans(function(){
$user = new User();
$user->user_mobile = '13345727773';
$user->save();
$user = new User();
$user->user_mobile = '13347818106';
$user->save();
},function(){
echo 'success';
},function(){
echo 'error';
});

Model Relation

if we want to add model relation,
4000
for example, there is a table named ==inf_user==, and a table named ==inf_cd_keys==, and each recored in ==inf_user== has one or many record inf ==inf_cd_keys==, so it’s easy to access the result with the flowing code;

First, get the user record

$this->user = User::all(['*'])->where([
'user_mobile' => '17010058640'
])->order([
'user_id' => 'desc',
'user_mobile' => 'desc'
])->limit(1)->getOne();

Then fetch if by the flowing:

$keys = $this->user->key
//The $keys is an array within objects or an object or null depends on the relation in User.php

Or the retrieve code can like this

$this->user = User::all(['*'])->with(['key','order'])->where([
'user_id < ' => 20
])->order([
'user_id' => 'desc',
'user_mobile' => 'desc'
])->get();
dump($this->user);

User.php

class User extends Model
{

protected $table = 'inf_user';

protected $primaryKey = 'user_id';

protected function key(){
return $this->hasMany(Key::class,'cdk_bind_user');
//return $this->hasOne(Key::class,'cdk_bind_user');
}
}

Key.php

class Key extends Model
{

protected $table = 'inf_cd_keys';

protected $primaryKey = 'cdk_id';

}

To DO LIST:

Wrap the collection data instead of an array
