<%= f.search_field :name_cont %>
<%= f.submit %>
<% end %>
<ul>
<% @users.each do |user| %>
<li><%= user.name %> [<%= user.devices.map {|device| device.name }.join(', ') %>]</li>
<% end %>
</ul>
<% if params[:q] %>
<%= link_to 'Export 1', dashboard_index_path({name: params[:q][:name_cont]}.merge({format: :csv})) %>
<% else %>
<%= link_to 'Export 2', dashboard_index_path(format: 'csv') %>
<% end %>
```
