Unpermitted parameters: avatar, avatar_cache

[Walter Colindres]

I am attempting set up a user avatar per the documentation. When I try and create a new user with an avatar, it says it can not upload a blank field --- even though a file is selected. When I look at the output I see the following error:

Unpermitted parameters: avatar, avatar_cache

user.rb:

class User < ActiveRecord::Base

  mount_uploader :avatar, AvatarUploader

  # Include default devise modules. Others available are:

  # :token_authenticatable, :confirmable,

  # :lockable, :timeoutable and :omniauthable

  devise :database_authenticatable, :registerable,

         :recoverable, :rememberable, :trackable, :validatable

  def create

    @user = User.create(user_params)

  end

  private

  def user_params

    params.require(:user).permit( :email, :password, :remember_me, :avatar, :avatar_cache, :remove_avatar )

  end

  #attr_accessible :email, :password, :remember_me, :avatar, :avatar_cache, :remove_avatar

  validates_presence_of   :avatar

  validates_integrity_of  :avatar

  validates_processing_of :avatar

end

avatar_uploader.rb

# encoding: utf-8

class AvatarUploader < CarrierWave::Uploader::Base

  # Include RMagick or MiniMagick support:

  # include CarrierWave::RMagick

  # include CarrierWave::MiniMagick

  # Choose what kind of storage to use for this uploader:

  storage :file

  # storage :fog

  # Override the directory where uploaded files will be stored.

  # This is a sensible default for uploaders that are meant to be mounted:

  def store_dir

    "uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"

  end

  # Provide a default URL as a default if there hasn't been a file uploaded:

  # def default_url

  #   # For Rails 3.1+ asset pipeline compatibility:

  #   # ActionController::Base.helpers.asset_path("fallback/" + [version_name, "default.png"].compact.join('_'))

  #

  #   "/images/fallback/" + [version_name, "default.png"].compact.join('_')

  # end

  # Process files as they are uploaded:

  # process :scale => [200, 300]

  #

  # def scale(width, height)

  #   # do something

  # end

  # Create different versions of your uploaded files:

  # version :thumb do

  #   process :scale => [50, 50]

  # end

  # Add a white list of extensions which are allowed to be uploaded.

  # For images you might use something like this:

  # def extension_white_list

  #   %w(jpg jpeg gif png)

  # end

  # Override the filename of the uploaded files:

  # Avoid using model.id or version_name here, see uploader/store.rb for details.

  # def filename

  #   "something.jpg" if original_filename

  # end

end

new.html.erb:

<%= form_for(resource, :as => resource_name, :url => registration_path(resource_name), :html => {:multipart => true}) do |f| %>

Thanks in advance!

I figured it out. The documentation is pretty spot on, though a bit outdated in some aspects. I was placing my permitted values in the wrong file.

[Robert Sefer]

Walter, would you mind posting your solution? I am tearing my hair out trying to figure this same thing out. Thanks

[Walter Colindres]

I believe I had to move my permitted values into the controller. Let me look at it again and I will try to reply soon. It's been awhile since I played with it.

that's right, it should be in the controller, not the model
