Its not possible to send File via Rest...

[thisisole]

i want to get my data via rest api.

for this i get a json like this:

"avatar": {
  "content": "/9j/4AAQSkZJRgAdBAQEAkACQAAD/4QBaRXhpZgAATU0AKgAAAAgABQMBAAUA\nAAABAAAASgMDAAEAAAABAAAAAFEQAAEAAAABAQAAAFERAAQAAAABAAAWJVES\nAAQAAAABAAAWJQAAAAAAAYagAACxj//bAEMAAgEBAgEBAgICAgICAgIDBQMD\nAwMDBgQEAwUHBgcHBwYHBwgJCwkICAoIBwcKCgoLDAwMDAcJDg8NDA4LDAwM\n/9sAQwECAgIDAwMGAwMGDAgHCAwMDAwMDAwMDAwMDAwMDAwMDAwMDAwMDAwM\nDAwMDAwMDAwMDAwMDAwMDAwMDAwMDAwM/8AAEQgAFQAUAwEiAAIRAQMRAf/E\nAB8AAAEFAQEBAQEBAAAAAAAAAAABAgMEBQYHCAkKC//EALUQAAIBAwMCBAMF\nBQQEAAABfQECAwAEEQUSITFBBhNRYQcicRQygZGhCCNCscEVUtHwJDNicoIJ\nChYXGBk=\n",
  "content_type": "image/jpg", 
  "filename": "test.jpg"
},

then i am getting this error:

Paperclip::AdapterRegistry::NoHandlerError in Api::V1::UsersController#create
No Handler found

so i use a function from this example http://paoloibarra.com/2014/09/27/Image-Upload-Using-Rails-API-And-Paperclip/ but it seems not to be working with paperclip_database

in my logs are following entries, but nothing is stored in the database. no other error... its just ignoring the avatar:

[paperclip] Database Storage Initalized.
[paperclip] Deleting files for avatar
[paperclip] Writing files for avatar

totally my fault...
