I have a gem that has an output with the following array (calling rate.inspect
)
[#<Fedex::Rate:0x007f9552bd6200 @service_type="FEDEX_GROUND", @transit_time="TWO_DAYS", @rate_type="PAYOR_ACCOUNT_PACKAGE", @rate_zone="4", @total_billing_weight="8.0 LB", @total_freight_discounts={:currency=>"USD", :amount=>"0.0"}, @total_net_charge="18.92", @total_taxes="0.0", @total_net_freight="18.19", @total_surcharges="0.73", @total_base_charge="18.19", @total_net_fedex_charge=nil, @total_rebates="0.0">]
I can't seem to figure out what to call on rate
to access the different values. I have tried rate.total_net_charge
but I get:
undefined method `total_net_charge' for #<Array:0x007f955408caf0>
Advice?

It appears that the object you have inside rate
is actually an Array
with one element, a Fedex::Rate
object. That is identifiable by the message:
undefined method `total_net_charge' for #<Array:0x007f955408caf0>
and much more subtly by the square brackets []
surrounding the <Fedex::Rate>
object. So to drill in to retrieve total_net_charge
, you would need to use an array method or index:
rate.first.total_net_charge
# Or by index
rate[0].total_net_charge
# Or assuming the array will sometimes have multiple objects
# loop or map to get them all
rate.each {|r| puts r.total_net_charge}
# or by map as an array of just the charges
rate.map(&:total_net_charge)
