推荐答案

最快捷的方法是使用 input_html 选项将一个类添加到您的输入中.

The quickest way to get that working is simply add a class to your input using the input_html options.

f.input :color, input_html: { class: 'colorpicker' }

然后在active_admin.js.coffee中，添加将.colorpicker输入框变成颜色选择器的代码.

And then in active_admin.js.coffee, add in the code to turn .colorpicker input fields into color pickers.

如果你打算制作很多它们，或者为它们添加选项，那么制作一个 自定义 Formtastic 输入，用于添加这些类并合并颜色选择器库可以选择的选项.

If you are going to be making a lot of them, or adding options to them, it might be worth it to make a custom Formtastic input that adds those classes and merges the options that can get picked up by the colorpicker library.
