Why is my object.save working in one place and failing in another?
require 'rubygems'
require 'mysql2'

@inverters=Inverter.where(:mac=>@mac)
Inverter.transaction do
  @inverters.each do |inverter|
    inverter.ip = @client_ip
    inverter.save               # Object is saved:)!
  end
end

require 'rubygems'
require 'mysql2'

@outputs=<a two dimensional hash>
Output.transaction do
  @outputs.each do |out|
    @newOut = Output.new
    @newOut.inverter_id = out[:inverter_id]
    @newOut.eac = out[:eac]
    @newOut.pac = out[:pac]
    @newOut.vac = out[:vac]
    @newOut.iac = out[:iac]
    @newOut.epv = out[:epv]
    @newOut.ppv = out[:ppv]
    @newOut.vpv = out[:vpv]
    @newOut.save                   # Object fails to save to db:(.

    # 2 lines of other code
  end
end
