Ruby on rails foreach with bootstrap3 string class

Question

I would like to use foreach loop through data and display this bootstrap data loading system having 3 columns per row, however I will need some rows for the amount of data, as shown below:

<div class="row"> <div class="col-md-4">*DATA HERE*</div> <div class="col-md-4">*DATA HERE*</div> <div class="col-md-4">*DATA HERE*</div> </div> <div class="row"> <div class="col-md-4">*DATA HERE*</div> <div class="col-md-4">*DATA HERE*</div> <div class="col-md-4">*DATA HERE*</div> </div> <div class="row"> <div class="col-md-4">*DATA HERE*</div> <div class="col-md-4">*DATA HERE*</div> <div class="col-md-4">*DATA HERE*</div> </div> 

Can anyone advise how to do this using foreach in rails, it is obvious that only class 1.row will be displayed below and put all the col-md-4 elements returned into it. I would like for him to create another .row class after it has reached 3 elements in a row and will start again. Hope this makes sense! What I still have:

 <div class="row"> <% @work.each do |w| %> <div class="col-md-6"> <%= w.image_url %> </div> <% end %> </div> 

Answer 1

use list # each_slice

 <% @work.each_slice(3) do |works| %> <div class="row"> <% works.each do |work| %> <div class="col-md-4">*work.name*</div> <% end %> </div> <% end %>
