Chain methods together in an Array (or string, split('.') ) and perform sequentially.Can be used to fetch related object's attributes without explicit ruby code (ie Front-End JS).NOTE: Will fallback to 'nil' instead of throwing error

try_chain.rb

## Controller
## value = send_chain(@activity, 'asset.product.code')

def try_chain(record, attrib)
  attrib.split('.').inject(record) {|o, a| o = o.try(a); o }
end

## Model
## value = send_chain('asset.product.code')

def get_column_value(attrib)
  attrib.split('.').inject(self) {|o, a| o = o.try(a); o }
end
