Ouch man, after going all my app to 2.2 , only fun…  
The last darn thing I forgot to test, an old legacy table I need to  
connect sometimes… broke…

To resume it, which change in ar could have broken this?

I can`t get my methods to fallback to the upcased ones anymore…

# DB Column =\> UP\_FIELD

find\_by\_up\_field , works in 2.1  
undefined method `find\_by\_up\_field’ for #Class:0xb62a4340, on 2.2

@model.up\_field, same thing.  
This works:  
@model[‘UP\_FIELD’]

It’s overriding extract\_attribute\_names\_from\_match which doesn’t exist  
any more (see this commit:

Morning Frederick,

I changed to " find (:first, :conditions…" then it works.  
It`s just 3 calls, will try fixing the class later.  
Thank you.
