Ruby on rails-paperclip do not save to the database

I'm a newbies to the rails world . What I'm trying to do is to add the abilities to user to add picture . I did some reaserch and, I found a gem called "paperclip",but after installing. Every time I try to upload a picture, I get "no file selected".

this is my models

attr_accessible :description, :image
 validates :description, presence: true
 validates :user_id, presence: true
 belongs_to :user 
 has_attached_file :image , :styles => { :small => "150x150>" }

 validates_attachment :image , :presence => true,
 :content_type => { :content_type => ["image/jpeg", "image/jpg","image/png","image/gif"] },
 :size => { :in => 0..10.kilobytes }

and this is my views

<div class="form-inputs">
 <%= f.input :image , label: "upload a picture !! " %>
<%= f.input :description , as: :text ,input_html: { rows:"3"} %>

Step by Step

Gem

gem "paperclip", "~> 3.0"

Terminal

$ bundle install
$ rails generate paperclip user image
$ rake db:migrate

User model

class User < ActiveRecord::Base
  attr_accessible:image, :description

  validates :description, presence: true
  validates :user_id, presence: true

  has_attached_file :image, styles: { medium: "320x240>"}

  validates_attachment :image, presence: true,
                            content_type: { content_type: ['image/jpeg', 'image/jpg', 'image/png', 'image/gif'] },
                            size: { less_than: 5.megabytes } # you wanna change that
  belongs_to :user

end

Your View is ok, don't forget to rake db:migrate and restart your Server
