Question

I am trying to create a custom method called full_address that takes the values of the address, city, state, and zip columns together.

Here is what my rails model location.rb looks like.

class Location < ActiveRecord::Base
  attr_accessible :address, :city, :state, :zip, :latitude, :longitude
  def full_address
    [address, city, state, zip].compact.join(', ')
  end
  geocoded_by :full_address
  after_validation :geocode
end 

Does that work? If so, how?

Thanks in advance.

Answer 1

Yes it works, adress, city, state and zip are methods generated to access the instance variable value. Here is an example to explain

def address
    "address"
end

def city
    "city"
end

def state
    "state"
end

def zip
    "zip"
end

[address, city, state, zip].compact.join(', ') # => "address, city, state, zip"
