我知道有三个主要的符号为whereActiveRecord方法提供参数:

1. 纯字符串
2. 排列
3. 哈希

指定and的where方法是直截了当:

# Pure String notation
Person.where("name = 'Neil' AND age = 27")

# Array notation
Person.where(["name = ? AND age = ?", 'Neil', 27])

# Hash notation
Person.where({name: "Neil", age: 27})

or为这个相同的where方法指定是为了哈希语法.可能吗？

# Pure String notation
Person.where("name = 'Neil' OR age = 27")

# Array notation
Person.where(["name = ? OR age = ?", 'Neil', 27])

# Hash notation DOESN'T WORK
Person.where({name: "Neil" OR age: 27})
