I have legacy Sql Server database and Rails applications. Column names in database are all in PascalCase (FirstName, CustomerId...). I''m searching for an easy way to use underscore_casing in Ruby and PascalCasing in database. I would like to write first_name in Rails for FirstName column in database. Just like translating Ruby in rjs templates to JavaScript cameCase convention. The best I found so far is a start of writing plugin: http://code.google.com/p/rails-mssql-tools/ Any advice would be great.

Check methods like..
human_name()
tableize()
underscore()
humanize()
pluralize()
singularize()

camelize and underscore will convert a string to required casing but I''m looking for something more general like: ActiveRecord::Base.camelize_table_column_names = true :-) like existing ActiveRecord::Base.pluralize_table_names --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

There is nothing that specific and generic but you can iterate through
all the attributes using meta and then do something to this effect
self.attributes.each do |method_name|
define_method(method_name.underscore)
method_name
end
define_method(method_name.underscore + "=", value)
method_name = value
end
end
This is very much pseudocode but I assure you this is possible and not
too hard to do.
Check methods like "define_method" out for more information. Even
better
look at "alias_attribute"
