| # Monkey patch to ActiveRecord to prevent 'implicit' checkouts. Currently tested with Rails 4.0.8, prob | |
| # should work fine in Rails 4.1 too. | |
| # | |
| # If you create a thread yourself, if it uses ActiveRecord objects without | |
| # explicitly checking out a connection, one will still be checked out implicitly. | |
| # If it is never checked back in with `ActiveRecord::Base.clear_active_connections!`, | |
| # then it will be leaked. | |
| # |
Note that this validation runs both after the file is uploaded and after CarrierWave has processed the image. If your base uploader includes a filter to resize the image then the validation will be run against the resized image, not the original one that was uploaded. If this causes a problem for you, then you should avoid using a resizing filter on the base uploader and put any specific size requirements in a version instead.
So instead of this:

| class User < ActiveRecord::Base | |
| # ... lots of persistence stuff | |
