rails attribute names camelcase issue

Question

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.

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

Just like translating Ruby in rjs templates to JavaScript cameCase convention.

Answer 1

Maybe set up aliases for all defined column names?

column_names.each do |column_name|
  alias_attribute column_name.underscore, column_name
end

You could add that to a concern and include that concern in all relevant models.
