Rails Alpha2 country to Real country name

I am using country gem https://github.com/hexorx/countries and trying to get the the country name from alpha2 country names. but it comes as [object object]. here is my code. 

render :json => @countries.map { |c| [c.id, ::ISO3166::Country[c.country]] }

This returns aplha2 fine as expected, which is saved in country column: 

render :json => @countries.map { |c| [c.id, c.country] }
Solution

  • You need to pass hash (data) instead of Country instance.

    render :json => @countries.map { |c| [c.id, ::ISO3166::Country[c.country].data] }

    If you want only country name, use name:

    render :json => @countries.map { |c| [c.id, ::ISO3166::Country[c.country].name] }
