MySql column names with "-" in them

Rails
1

I am getting warnings in my logs for updates to a table I created that
has column names from an XML response file i get from Google Checkout
notifications. I basically log the orders into a mimicked table.
Column names examples are “total-refund-amount” and so on.

Below are the warnings. Any ideas on how to supress this? my updates
are working. But its a pain to scroll through logs when one order
creates about 300kb of text regarding these warnings.

Has anybody experienced this? found a work-around?

Exception occurred during reader method compilation.
Maybe total-refund-amount is not a valid Ruby identifier?
compile error

or ‘;’
def total-refund-amount; missing_attribute(‘total-refund-amount’,
caller) unless @attributes.has_key?(‘total-refund-amount’);
(v=@attributes[‘total-refund-amount’]) &&
ActiveRecord::ConnectionAdapters::MysqlColumn.value_to_decimal(v); end
^

The easiest solution would be to rename your fields with undescores to
follow Rails conventions.

If you need to stuff map easily, a substitution on ‘-’ for ‘_’ is easy
enough to handle in your processing code.
