Question

In my rails view(index.html.erb), i have following structure

<div>
   <%= render :partial => "create" %>
</div>

<div>
   <%= render :partial => "show" %>
</div>

In controller’s create action if i use

def create 
  render :update do |page|
     page.replace_html 'show', :partial => 'show'
  end
end

I get below error

undefined method `map' for nil:NilClass

because the instance variable doesnt get initialized from controller

If i use

def create
    render :file => "_show.erb"
end

I get template missing error. because the base layout file is not getting rendered.

I basically want to update the partial on create event.

Any suggestions would be of great help.

The solution :layout => false works.

But, newly added entry doesnt come until page refresh

 @entry = Model.find(:all) 

in the _show.html.erb doesnt get updated

You can try like this it will surely works…………..

   def create
     render :partial => "show" ,:layout => false
   end

but your page should be name like

_show.html.erb
