Here’s my error:

NameError (undefined local variable or method `gmap\_full\_address’ for  
#Class:0x7f9bae66e788):  
app/models/address.rb:12

here’s the model:

class Address \< ActiveRecord::Base

attr\_accessible :name, :address1, :address2, :city, :state\_id,  
:country\_id, :postal\_code,  
:carrier\_id, :time\_zone, :gmap\_lat, :gmap\_long

…

after\_save {  
logger.info “attempting geocode retrieval for  
#{gmap\_full\_address}” \<------------------  
result = get\_geocode(gmap\_full\_address)  
gmap\_lat = result[:latitude]  
gmap\_long = result[:longitude]  
save  
}

def gmap\_full\_address  
address1 + ", " + city + ", " + state.abbrev  
end

I don’t understand why it’s saying gmap\_full\_address is indefined.

Anyone know why?

Because you’ve used the block form of after\_save, so self inside that  
block is the class itself, not a particular instance
