Rails Fixtures with Legacy Database

My setup was:

MySQL Table name: TABLENAME (all caps)
Rails Model name: TableName (camel case)

1. The fixture file has to be TABLENAME.yml (not case sensitive)
2. fixtures() takes the symbol name of the Model, in this case :tableName (note the first lowercase letter) This is the bit that drove me mad - i was writing fixtures :TableName which appeared to work, but then the test failed if I tried TableName(:foo)
3. Now you can write tableName(:foo)
