I have tried many times to save new image after carrierwave keep file after validation fail, but not success.

<%= form_for @user, :html => {:multipart => true} do |f| %>
  <p>
    <label>My Avatar</label>
    <%= f.file_field :avatar %>
    <%= f.hidden_field :avatar_cache %>
  </p>
<% end %>

I had to sanitize parameter for :avatar, :avatar_cache, ...

It has still display new image ,but when i save the form the new image not saved.

Make sure :avatar_cache is included in your permitted params.
