Rails 3.1.0, geokit, with error acts_as_mappable

问题

I am getting the

undefined local variable or method `acts_as_mappable'

error when using geokit, and after tons of Goggling and attempts, I cannot seem to be able correct the problem.

Basically, I have the following gems installed:

geokit (1.6.0, 1.5.0)
geokit-rails31 (0.1.3)

and have the following in my model

class House < ActiveRecord::Base
  acts_as_mappable
end

and Gemfile:

gem 'geokit', '>= 1.5.0'
gem 'geokit-rails31'

I get the error with or without doing the following in my local app.

rails plugin install git://github.com/jlecour/geokit-rails3.git

Okay - Here is the solution for anyone that needs help on how I got it to work...

Make sure your project Gemfile does not contain any geokit info of any kind.

install geokit

> gem install geokit

> gem list geo
*** LOCAL GEMS ***
geokit (1.6.0, 1.5.0)

uninstall geokit-rails3 and geokit-rails31

> gem uninstall geokit-rails31 geokit-rails3

in your project, at the root level:

> rails plugin install git://github.com/jlecour/geokit-rails3.git

edit the spec

> vi vendor/plugins/geokit-rails3/geokit-rails3.gemspec

change rails dependency line to be

s.add_runtime_dependency 'rails', '>= 3.1.0'

now, edit the Gemfile to include the gem

gem 'geokit-rails3', :path => 'vendor/plugins/geokit-rails3'

Note, the Gemfile only contains an entry for the geokit-rails3, and no entries for normal geokit gem. i.e. there is not a "gem 'geokit', '>= 1.5.0'" entry

then in your application root, do a

bundle install

It should be setup, and you can now follow a typical tutorial - as described in the git instructions
