Question

我在Ruby-on-Rails 教程中一直关注练习。

创建三个名为 person1 , person2 , >3 ,以及下的第一个和最后一个名字:First 和 :First 和 :Last 。然后创建一个 params hash,这样, params[:father] 就是 person1 , 是 person2 , 是 , 是 parems[:ccode>person3 。



有人能建议如何解决这个问题吗?

Answer 1

person1 = {:first =>  Al ,    :last =>  Bundy }
person2 = {:first =>  Peggy , :last =>  Bundy }
person3 = {:first =>  Kelly , :last =>  Bundy }
params = {
 :father => person1,
 :mother => person2,
 :child  => person3
}
params[:father][:first] #=>  Al

Answer 2

我发现这感觉更熟悉,

person1 = {first: "Papa", last: "Bear"}
person2 = {first: "Mama", last: "Bear"}
person3 = {first: "Baby", last: "Bear"}
params = {father: person1, mother: person2, child: person3}
