如何从具有空格的字符串中创建符号? [英] How to create a symbol from a string that has whitespaces?

问题描述

我正在为电影名称存储创建一个Ruby哈希.

I am creating a Ruby hash for movie names storage.

当哈希键是包含空格的字符串时，它就可以正常工作.

When the hash's keys are strings that contains whitespaces, it works just fine.

如:

movies = {"Avatar" => 5, "Lord of the rings" => 4, "Godfather" => 4}

现在我正在尝试将符号的使用替换为符号:

Now I am trying to replace the use of strings with symbols:

movies = {Avatar: 5, Lord of the rings: 4, Godfather: 4}

显然那是行不通的.

Ruby如何在符号命名中处理空格?

自行尝试

"Lord of the rings".to_sym
