Ruby on Rails

HI
  
  Firstly we need install paperclip, imagemagic on your machine , then we need define relation to the model suppose product and product_images. we need to define accepts_nested_attributes_for :product_images in your model then
 
 when you create object of model we need build product object to the product_iamges model.

In your view create _form.html.erb and _product_image_fields.html.erb.

In your form.html.erb write above code

 <div class="control-group">
      <label class = "control-label">Select image<abbr title="required">*</abbr></label>
        <%= f.fields_for :product_images do |builder| %>
          <%= render 'product_image_fields', :f => builder %>
        <% end %>
      <div class="controls">
        <%= link_to_add_fields "Browse more image", f, :product_images %></p>
      </div>
    </div> 
And your product_images.html.erb write above code
<div>
  <%= f.file_field :photo %>

    <span>
      <%= f.check_box :default_image, {checked: false}  %>
      Default Image
    </span>

    <span>&nbsp;<%= link_to_remove_fields "remove", f %></span>

  </div>

 This code work perfectly to me...
