def block in rake task

Question

I got undefined local variable or method 'address_geo' for main:Object with the following rake task. What's the problem with it?

include Geokit::Geocoders  namespace :geocode do   desc "Geocode to get latitude, longitude and address"   task :all => :environment do     @spot = Spot.find(:first)     if @spot.latitude.blank? && [email protected]?       puts address_geo     end      def address_geo       arr = []       arr << address if @spot.address       arr << city if @spot.city       arr << country if @spot.country       arr.reject{|y|y==""}.join(", ")     end   end end

Update: Gotcha

This potentially adds the method to global scope and will conflict with any other method with the same name. Look at @Hula_Zell's answer https://stackoverflow.com/a/44294243/584440 for a better way.

Original answer

You are defining the method inside the rake task. For getting the function, you should define outside the rake task (outside the task block). Try this:

include Geokit::Geocoders  namespace :geocode do   desc "Geocode to get latitude, longitude and address"   task :all => :environment do     @spot = Spot.find(:first)     if @spot.latitude.blank? && [email protected]?       puts address_geo     end   end    def address_geo     arr = []     arr << address if @spot.address     arr << city if @spot.city     arr << country if @spot.country     arr.reject{|y|y==""}.join(", ")   end end
