Limiting characters/words in view - ruby on rails

I am displaying recent comments on the home page of a blog application I am building in Ruby on Rails. I want to limit the number of characters that are displayed from the body column of the comments table.

I am assuming I can just add something to the end of the code for <%=h comment.body %> but I don't know what that would be yet as I am new to both Ruby and Rails.

Here is the code I have in the /views/posts/index.html.erb file:

<% Comment.find(:all, :order => 'created_at DESC', :limit => 5).each do |comment| -%>
    <p>
        <%=h comment.name %> commented on 
        <%= link_to h(comment.post.title), comment.post %><br/>
        <%=h comment.body %>
        <i> <%= time_ago_in_words(comment.created_at) %> ago</i>
    </p>
<% end -%>
Solution

  • Try the truncate view helper

    <%=h truncate(comment.body, :length => 80) %>
