Redmine

Goal: I want to set a custom_field value only for issues created via Email

My Attempt: Patch mail_handler.rb to set custom field at custom_field_values_from_keywords. This prevented emails from even being created as tickets. Am I chaining the wrong function?

module MailHandlerPatch

  def self.included(base)
    base.send(:include, ClassMethods)

    base.class_eval do 
      alias_method_chain :custom_field_values_from_keywords, :mod
    end
  end

  module ClassMethods

    def custom_field_values_from_keywords_with_mod(customized)
      arr = custom_field_values_from_keywords_without_mod
      Rails.logger.info "****** #{arr.inspect}  " 

      arr["27"] = "email" 
      return arr
    end

  end

end

MailHandler.send :include, MailHandlerPatch
