使用simple_form时，country_select的正确代码是什么？

Question

Without simple_form, my code for country_select will be:

<%= f.label :country %>
<%= f.country_select :country, include_blank: true %>

But with simple_form gem installed, will this be the code?:

<%= f.input :country %>

Answer 1

Yes, Simple Form will pick up the string "country" in the attribute name, and automatically apply country_select underneath, provided you include the country_select gem in your Gemfile:

gem 'country_select'

You can force the mapping, if necessary with:

<%= f.input :field_name, as: :country %>
