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

Rake enables you to define a set of tasks and the dependencies between them in a file, and then have the right thing happen when you run any given task. The combination of convenience and flexibility that Rake provides has made it the standard method of job automation for Ruby projects.
Including => :environment will tell Rake to load full the application environment, giving the relevant task access to things like classes, helpers, etc. Without the :environment , you won't have access to any of those extras.
Rake is a tool you can use with Ruby projects. It allows you to use ruby code to define "tasks" that can be run in the command line. Rake can be downloaded and included in ruby projects as a ruby gem. Once installed, you define tasks in a file named "Rakefile" that you add to your project.
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 If you love us?
