issue with country select

[royzinn]

Hi,
I'm using the gem:
gem 'activeadmin', github: 'gregbell/active_admin'

and i'm trying to use the country select using the country_select gem. I have created the form:

= semantic_form_for [:admin, @team] do |f|
  = f.inputs do
    = f.input :name
    = f.input :country, as: :country, priority_countries: ["IL", "ES", "GB", "FR"]
  = f.actions :commit

but I keep getting this error: wrong number of arguments (4 for 1..3) no matter what I do.
Any suggestions?
Thanks,
Roy

Are you using rails 4?
I think it is related with formtastic, not activeadmin
see formtastic/formtastic#1048 and formtastic/formtastic#1049

If you are using the edge version of the country_select gem, it does not appear formtastic has been updated to handle it.

You can override the formtastic country input like this to handle country_select's updated method parameters:

# app/inputs/country_input.rb
class CountryInput < Formtastic::Inputs::CountryInput

  def to_html
    raise "To use the :country input, please install a country_select plugin, like this one: https://github.com/stefanpenner/country_select" unless builder.respond_to?(:country_select)
    input_wrapping do
      label_html <<
      builder.country_select(method, input_options, input_html_options)
    end
  end

end

I'm experiencing the same issue as described here.

My setup initially only included the country_select gem:

gem "country_select", "~> 8.0"

Solution:
Adding the countries gem to my Gemfile and running bundle install resolved the problem:

gem "countries", "~> 5.7"

My f.input configuration:
Here's how my country input field is configured, in case it's relevant:

f.input :country, as: :country,
          selected: "US",
          priority_countries: [ "US", "GB" ],
          except: [ "IL" ],
          prompt: "Select a Country"
