Arel is a Relational Algebra for Ruby. It 1) simplifies the generation complex of SQL queries and it 2) adapts to various RDBMS systems. It is intended to be a framework framework; that is, you can build your own ORM with it, focusing on innovative object and collection modeling as opposed to database compatibility and query generation.

CarrierWave storage for Dropbox

This gem adds to carrierwave a storage facility which will use the PostgreSQL's oid datatype to reference a large object residing in the databse. It supports up to 2GB files, though it's better suited for smaller ones. Makes life easier for fast prototyping and put all your data in the same place, allows one backup for all your data and file storage in heroku servers.

Lazily loads large columns on demand. By default, does this for all TEXT (:text) and BLOB (:binary) columns, but a list of specific columns to load on demand can be given. This is useful to reduce the memory taken by Rails when loading a number of records that have large columns if those particular columns are actually not required most of the time. In this situation it can also greatly reduce the database query time because loading large BLOB/TEXT columns generally means seeking to other database pages since they are not stored wholly in the record's page itself. Although this plugin is mainly used for BLOB and TEXT columns, it will actually work on all types - and is just as useful for large string fields etc.

Gems main responsibility is to provide service for copying Carrierwave files between records
