[分享] 更方便在 Rails 内写 OR 语句的 gem at January 17, 2017
关于直接写 SQL 是否比较好看，每个人观感都不一
我的确"考虑的有点简单"，or 这方法也是 Rails 5 才新加的功能
只希望这个小工具能给还身在 Rails 3, Rails 4 的人多几项选择啰！

要写
```
Person.where(name: 'Pearl').or(Person.where(age: 24))
```
还是
```
Person.where(name: 'Pearl').or(age: 24)
```
或是
```
Person.where('name = ? OR age = ?', 'Pearl', 24)
```
就看个人抉择呗，各語法都支援的
[分享] 更方便在 Rails 内写 OR 语句的 gem at January 17, 2017
简单不就是一件好事么？
其实就是个语法糖，举例来说：
Rails 5:
```
xxx = Model.join(yyy)
result = xxx.where(zzz).or(xxx.where(aaa)).or(xxx.where(bbb))
```
rails_or:
```
xxx = Model.join(yyy)
result = xxx.where(zzz).or(aaa).or(bbb)
```
