Question

I am getting error at in registrationscontroller at 15 and 99 I have done following in my app

def user_params
#assumption: user params are coming in params[:user]
params.require(:user).permit(:first_name, :last_name, :mobile, :uid, :provider, :avatar )
end
in user.rb

has_attached_file :avatar, :styles => { :medium => "300x300>", :thumb => "100x100>" }, :default_url => "/images/:style/missing.png"
validates_attachment_content_type :avatar, :content_type => /\Aimage\/.*\Z/

in migration

class AddAvatarToUsers < ActiveRecord::Migration
  def change

add_attachment :users, :avatar

  end
end

ActiveRecord::UnknownAttributeError in MyDevise::RegistrationsController#create

app/controllers/my_devise/registrations_controller.rb:99:in `build_resource'
app/controllers/my_devise/registrations_controller.rb:15:in `create'

Extracted source (around line #99):

# Signs in a user on sign up. You can overwrite this method in your own

Build

I think your problem is to do with Devise building your objects:

def build_resource(hash=nil)
    self.resource = resource_class.new_with_session(hash || {}, session)
end

You're confusing Devise's operations (it's best to leave Devise alone & add functionality on top of it)

Extra Fields

Here's what I'd do:

Set up Devise to handle extra attributes
Add extra attributes after registration

Params

class ApplicationController < ActionController::Base
  before_filter :configure_permitted_parameters, if: :devise_controller?

  protected

  def configure_permitted_parameters
    devise_parameter_sanitizer.for(:sign_up) << :avatar
  end
end

Fields

You can use these resources to add extra attributes to your model when registering new users:

From the looks of it, changing the params selector, you should be able to upload the avatar image through the registration form

Nice you might want to consider accepting my answer ;) – Richard Peck Feb 28 '14 at 16:18 — Richard Peck, Feb 28 '14 at 16:18
