在Ajax中加载页面

I am trying to use Wiselinks gem.

Jquery code:

window.wiselinks = new Wiselinks("#wiselinks");

views/layout/application.html.erb :

<div id="wiselinks" style="width: 100%"> <%= yield %> </div>

Show page html code:

<div class="profile_bar"> 
    some code I want to keep after loading here 
</div>
<a href="/users/feed/<%= @user.id %>" data-push="true"> 
</a>

Now, the feed page is loaded in #wiselinks div and url is changed correctly. But I would like to keep the profile bar div when loading different pages. I could use a partial but I will have to redo the same queries many times to get the data for the partial.

what is the best solution to solve this problem?
