Create Rails models for every table in the database

model_creator.rb

invalid_chars = [' ', '$', '(', ')']

ActiveRecord::Base.connection.tables.each do |table_name|
  name = table_name
  invalid_chars.map { |ch| name = name.gsub(ch, '_') }
  name = name.camelize
  name = name + "_" if Module.const_defined? name

  eval %{
   class #{name} < ActiveRecord::Base
      self.table_name = "#{table_name}" ;
      self.primary_key = "#{ActiveRecord::Base.connection.primary_key table_name}" ;
    end
  }
end
