Rails: Ignoring non-existant attributes passed to create()

Question

I have the following Rails model:

class CreateFoo < ActiveRecord::Migration
  def self.up
    create_table :foo do |t|
      t.string :a
      t.string :b
            


        

Answer 1

I think using the attr_accessible method in the model class for Foo would achieve what you want, e.g.,:

class Foo < ActiveRecord::Base

  attr_accessible :a, :b, :c

  ...
end

This would allow the setting/updating of only those attributes listed with attr_accessible.
