# ActiveAdmin already includes the necessary jquery in active_admin/base,
# so just add this to javascripts/active_admin.js after //= require active_admin/base

# model_name - you guessed it, the name of the model we are calling sort on.
#              This is the actual variable name, no need to change it.

# active_admin and formtastic seem kinda picky about displaying both the
# image and the file input together here... in fact, it seems like this
# is the ONLY way to do this? Adding anything else after the image_tag squashes it.
