Rails 4 Paperclip with Devise, file saving error - ruby-on-rails-4

Question

I'm using devise gem with paperclip to handle authentication and upload pictures. Problem is that I have used paperclip on the same model twice for storing two pictures (let's call those paperclip columns :avatar , :superbadge), my model name is User.
Now, when I choose to upload two pictures, my rails application ignores the first file that I have chosen, instead It uses second chosen file and saves it in the first paperclip column, leaving second paperclip column blank. How do I fix it?
My application controller:
class ApplicationController < ActionController::Base
protect_from_forgery with: :exception
before_action :configure_devise_permitted_parameters, if: :devise_controller?
protected
def configure_devise_permitted_parameters
registration_params = [:name, :email, :password, :password_confirmation,:avatar,:superstarbadge]
if params[:action] == "update"
devise_parameter_sanitizer.for(:account_update) {
|u| u.permit(registration_params << :current_password)
}
elsif params[:action] == "create"
devise_parameter_sanitizer.for(:sign_up) {
|u| u.permit(registration_params)
}
end
end
end
My User.rb model:
class User < ActiveRecord::Base
devise :database_authenticatable, :registerable, :validatable
has_attached_file :avatar, :styles => { :small => "100x100>" }
validates_attachment_content_type :avatar, :content_type => /\Aimage\/.*\Z/
has_attached_file :superstarbadge, :styles => { :tiny => "100x100>" }, :default => "superbadge.jpg"
validates_attachment_content_type :superstarbadge, :content_type => /\Aimage\/.*\Z/
has_many :questions
has_many :answers
def to_s
email
end
end
My form_for for creating new user with devise gem (I'm using slim template language not erb):
h1 Sign up
= form_for(resource, as: resource_name, url: registration_path(resource_name), :html => { :multipart => true }) do |f|
= devise_error_messages!
.field
label= f.label :name
= f.text_field :name, autofocus: true
.field
label= f.label :email
= f.email_field :email, autofocus: true
.field
label= f.label :password
= f.password_field :password, autocomplete: 'off'
.field
label= f.label :password_confirmation
= f.password_field :password_confirmation, autocomplete: 'off'
.field
= f.label :avatar
= f.file_field :avatar
.field
= f.file_field :avatar
div
= f.submit "Sign up"

Answer 1

Both the file_field's in your form are referring to avatar field so when you submit the form the second chosen file (i.e., latest) gets saved as avatar. There is no file_field for superstarbadge so it never gets saved.
You need one file_field for avatar and other one for superstarbadge. So, your code should look like:
.field
= f.label :avatar
= f.file_field :avatar
.field
= f.file_field :superstarbadge ## This one should be superstarbadge and NOT avatar
