camelCase to snake_case

[aw]

I am using Lift-Mapper with Oracle. Oracle is a case-insensitive
database. For Hibernate projects, I have used the Enhanced Naming
Convention to translate Java camelCase to a more Oracle friendly
snake_case. I am interested in doing the same thing with Lift Mapper/
Record.

In the mean time, I need to override dbTableName and dbColumnName, but
I'd like to avoid that and just agree on the convention.

I could imagine that the Database Provider would maintain a flag to
say whether the database is case sensitive or not, and then based on
that flag, would pass either the camelCase directly (for case
sensitive), or snake_case(camelCase) (for case insensitive).

(Or, does this functionality already exist and I just haven't
configured it properly?)

Probably not too hard to do on your own via a trait: the trait should extend MappedField, override dbColumnName, and calculate it based on getClass.

It's not currently a feature, but please open a ticket http://github.com/dpp/liftweb/issues .  We'll get it into M8

While this works, I think it is too tedious to do on all classes and
fields. I think a better approach would be to make the Connection
naming aware and just "do the right thing" (tm) based an the specified
naming convention

Acually, I'm going to do it based on a single function in MapperRules.

Thank you. I will open an Issue for this. I was reluctant to do it
thinking that it was a user issue. ;-)
