Splitting string into linked words

Question

So I have standart scaffold cycle that prints a string of tags of a meet.

<% @meets.each do |meet| %>
      <p class="MeetTags"><%= meet.tags %></p>
   <% end %>

How can I separate string of for example 3 words, so that each would be in separate box. Thank you!

You can do some think like

<% @meets.each do |meet| %>
  <% meet_tags = meet.tags.split(' ') %>
  <% meet_tags.each do |meet_tag|%>
   <p class="MeetTags"><%= meet_tag %></p>
  <%end%>
<% end %>

Assuming that your tags are joined with space:

<% @meets.each do |meet| %>
  <% meet.tags.split(' ').each do |word| %>
    <p class="MeetTags"><%= word %></p>
  <% end %>
<% end %>

And how can I get eat coffee lunch instead of ["eat coffee lunch"] – Danielius Visockas Nov 26 '13 at 09:58
@DanieliusVisockas change comma into space in `split` 'condition', just as I did in edited answer. – Marek Lipka Nov 26 '13 at 10:02
I want to get rid of [ and " symbols. If I change space to comma I get ["eat", "coffee", "lunch"] – Danielius Visockas Nov 26 '13 at 10:06
@DanieliusVisockas You mean, you get these in HTML? – Marek Lipka Nov 26 '13 at 10:08
Yes, I've pasted it from my site. – Danielius Visockas Nov 26 '13 at 10:14
@DanieliusVisockas ok, it was my mistake. Please check out edited answer. – Marek Lipka Nov 26 '13 at 10:40
Thank you, symbols to complete comment – Danielius Visockas Nov 26 '13 at 11:38

your problem is that meet.tags is an array, so you're telling rails to display the array: that's why you're seeing the square braces.

If you want to split tags into groups of 3, and then show them separated by spaces, you could do this:

<% @meets.each do |meet| %>
  <% tag_arr = meet.tags.split(' ') %>
  <% tag_arr.in_groups_of_3.each do |tag_subarr|%>
   <p class="MeetTags"><%= tag_subarr.reject(&:blank?).join(" ") %></p>
  <%end%>
<% end %>

I'm using .reject(&:blank?) because the in_groups_of method will pad the last subarray out with nil, which will mess up your formatting, and maybe cause other problems if you try and do anything with the member elements of tag_subarr.
