To use the :country input, please install a country_select plugin

Question

I have a country attribute to my guidelines model. I don\'t want to use a plugin, I just want to have country as a string. Everything is working until I try to edit a guide

Answer 1

You're using ActiveAdmin, so you're also using Formtastic.

In Formtastic, in the file formtastic/lib/formtastic/inputs/country_input.rb it clearly says:

# Rails doesn't come with a `country_select` helper by default any more, so you'll need to do
# one of the following:
#
# * install the [country_select](https://github.com/stefanpenner/country_select) gem
# * install any other country_select plugin that behaves in a similar way
# * roll your own `country_select` helper with the same args and options as the Rails one

I would add gem 'country-select' to your Gemfile and do a bundle install as is the simplest and fastest solution.
