ruby on rails - Mongoid paper clip photo is removed when parent.update_attributes!(attr) called -

I have 2 models

users models too many The embedded image is as low as

  class user Mongoid :: Document Field: user_name, type: string embeds_im: picture, cascade_kelbox: true ... and  

Image model is implemented as follows

  Mogoyade in class picture :: documents include mogaid :: paperclipf Land: Description, type: string is_mangode_tated_file: photo, default_style: '', default_style :: thumb, url: "/: attachment /: id /: style. Extension", style: {origin: ['2000x1200': jpg ], Thumbs: ['600x400 #',: jpg]}, convert_points: {all: '-quality 90-script-background black-flaton + matte'} ... and

Issue User_controller # update

  def update ... @ user.update_attributes! (User_params) ... end def user_par Ams params.require (: user) .permit (: user_name, picture: [: id,: description]) end  

Expiration of #update is passed to the description of the picture from the id ... and it does but the uploaded image should not be updated After it has been removed?

How can I update the description of the uploaded photo @ user.update_attributes! (User_params) ?

Removal after being tested!

  image_param = params [: user] .delete (: pictures) @ user.pictures.where (: id.in => pictures_params.map (& id: id)) . Do each. Picture | Pic.set (: description, pictures_params.find {| p | p [: id] == pic.id} [: description]) end
