  1. \n
    current_user.uploads is AREL object. So u have to specify what upload do u want to update. For example first user upload.<\/p>\n
    current_user.uploads.first.update_attributes(params[:upload])\n<\/code><\/pre>\n
    or maybe<\/p>\n
    @upload = current_user.uploads.find(params[:upload].delete(:id))\n@upload.update_attributes(params[:upload])\n<\/code><\/pre>\n
    or all records<\/p>\n
    @upload = current_user.uploads\n@upload.update_all(params[:upload])\n<\/code><\/pre>\n<\/li>\n
  2. \n
    try this instead:<\/p>\n
    @upload.update_attributes(params[:upload])\n<\/code><\/pre>\n<\/li>\n
  3. \n
    @upload = current_user.uploads, it is given you the array of uploads object, but attributes methods is apply for single object. So you have to apply each methods<\/p>\n
    @uploads = current_user.uploads\n@uploads.each do | upload|\n  upload.update_attributes(params[:upload])\nend\n<\/code><\/pre>\n<\/li>\n<\/ol>\n
