[LRUG] How does Rails decide how to parse ambiguous dates?

[Mr Jaba]

I believe the type casting happens in the database adapter itself, for
example, the MySQL adapter will do it, as would the Postgres one.

http://api.rubyonrails.org/classes/ActiveRecord/ConnectionAdapters/Column.html#method-c-string_to_date

You can always override the Model's accessor and do your own conversion in
there?
