Rails选择国家下拉？ [英] Rails Select Drop Down for States?

问题描述

我想知道是否有一些已经内置的rails功能，以便它会与所有的美国州一起创建一个选择下拉列表，所以我不必手动输入。我在网上搜索，但我找不到任何东西。任何关于怎么做的建议，我不必手动输入所有的状态。

I was wondering if maybe there was some already built in function for rails so that it would create a select drop down list with all the U.S. states so I wouldn't have to enter it manually. I searched online but I was unable to find any. Any suggestions on what to do so I don't have to manually enter all the states?
