How to add a already loaded image into browser, into a form field of type 'file'.


/ Published in: HAML
Save to your folder(s)

This code can collect and Date and Description from user, then User can drag/drop an image in drop area to load it into browser OR if browser doesn't support drag/drop, then user can see a normal file input instead to browse and choose an image. after that user can determine a crop area for corresponding image. until here everything works charming. If I use a file input as a form field, after submit, in controller function ( by using WebImage static methods) I can get all images existing in request easily. Problem is when I use a drag/drop method to load a image in browser. then there is no File object in Request to could be retrieved in Controller using WebImage methods.
How can I add this File object somehow to Request?
I can't use Ajax because sometimes user needs to load image in browser and determine a Crop area for that.
