dadi#Dadis-iMac brainstore (AddingMailChimp) $
I've been following this link http://cheshireoctopus.github.io/blog/2014/01/23/mailchimp-plus-gibbon-plus-rails-create-a-basic-sign-up-form/
and this one http://aspiringwebdev.com/e-mail-in-rails-with-mailchimp-and-mandrill-a-comprehensive-guide/
and I have done various modifications according to stackoverflow posts but still nothing seems to work.
I don´t have a clue what is going on here but it would be very helpful if someone could advise me...
this is my config/initializers/gibbon.rb
require 'gibbon'
gibbon = Gibbon::Request.new(api_key: "myAPIkey")
Gibbon::API.timeout = 15
Gibbon::API.throws_exceptions = false
emailapi_controller.rb
class EmailapiController < ApplicationController
def index
end
def subscribe
#list_id = "myLISTid"
gb = Gibbon::API.new
gb.lists.subscribe({
:id => #list_id,
:email => {:email => params[:email][:address]}
})
end
end
Gemfile.rb

Answer 1

If anyone is interested I managed to fix this by doing the following.
in the Gemfile I changed gem 'Gibbon' to gem 'gibbon', :git => 'https://github.com/amro/gibbon.git'
then I changed the emailapi_controller.rb to
class EmailapiController < ApplicationController
def subscribe
#list_id = ENV["MAILCHIMP_LIST_ID"]
gibbon = Gibbon::Request.new
gibbon.lists(#list_id).members.create(
body: {
email_address: params[:email][:address],
status: "subscribed"
}
)
respond_to do |format|
format.json{render :json => {:message => "You have been Successfully added to the list! :)"}}
end
end
end
the initializers/gibbon.rb is supposed to be like this:
Gibbon::Request.api_key = ENV["MAILCHIMP_API_KEY"]
Gibbon::Request.timeout = 15
Gibbon::Request.throws_exceptions = false
and the MAILCHIMP_API_KEY and MAILCHIMP_LIST_ID are stored in a application.ymlcreated by the figaro gem
hope this can help if someone stumbles on the same error.

Answer 2

The current README for Gibbon refers to Gibbon 2.x. I suggest using a release version instead of pointing your Gemfile to github. e.g.
gem 'gibbon', '~>2.2.4'

Answer 3

Try in your Gemfile, not sure why bundler is not doing it by default
gem 'gibbon', '>= 3.4.0', require: 'gibbon'
