Rails 3 Model Mapping Certain Columns To Different Model Attributes

I have the old legacy table called 'DXFTACCTS', and I created Rails model 'Account'. class Account < ActiveRecord::Base set_table_name 'DXFTACCTS' end The problem is that DXF

Solution 1:

You can use the method alias_attribute like this:

classAccount < ActiveRecord::Base
  set_table_name "DXFTACCTS"

  alias_attribute :first_name, :XORFNAMEend

alias_attribute creates the methods first_name, first_name= and first_name? which will map to the XORFNAME column in your table. However, you will NOT be able to use it in conditions like regular columns. For example:

Account.all(:conditions => { :first_name =>"Foo" })

That will fail...

Solution 2:

I think something like definition of getter and setter methods should do the trick:

classAccount < ActiveRecord::Base    

  ...

  deffirts_nameself[:XORFNAME]
  end

  def first_name= value
    self[:XORFNAME] = value 
  end

  ...

end
