Rails通过local_assigns部分循环

Question

I'm populating a partial with many instance variables in the locals hash. Is there a way to pull multiple instance variables from local_assigns in the partial?

<%= render 'tabs', :locals => {:tab1 => @news, :tab2 => @people, :tab3 => @tags} %>

In the partial I'd like to create a dynamic set of tabs based on the number of instance variables I populate the locals with.

<% local_assigns.each do |local_assign| %>
  <% local_assign.each do |tabs| %>
     <!-- Grab tab class name -->
     <li class="tab"><%= tabs[:class] %></li>
  <% end %>
<% end %>

Answer 1

Why don't you just pass it as an array

render 'tabs', :locals => {:tabs => [@news, @people, @tags]} %>

in your view

<% tabs.each do |tab| %>
   <!-- Grab tab class name -->
   <li class="tab"><%= tab[:class] %></li>
<% end %>

Thanks Vimsha I ended up using collection instead of locals and created the instance variable in the controller.

Controller
@tabs = [@news, @people]

View
<%= render 'tabs', :collection => @tabs %>
