Uncaught ReferenceError: JST is not defined

Using Rails 3.2.22

Here's the console stack trace:

Within editor.js it's referring to this method where JST is being referenced:

/**
  * Adds the wysihtml5 toolbar. If uploads are enabled, also adds the
  * necessary file inputs for uploading.
  */
 Editor.prototype._addToolbar = function() {
   var template = JST['active_admin/editor/templates/toolbar']({
     id: this.$el.attr('id') + '-toolbar'
   })

   this.$toolbar = $(template)

   if (config.uploads_enabled) {
     var _this = this
     this.$toolbar.find('input.uploadable').each(function() {
       _this._addUploader(this)
     })
   }

   this.$el.find('.wrap').prepend(this.$toolbar)
 }

I haven't done anything with the initialization file yet - I don't want to upload images. Do I still need to fill this out?
