Ruby on Rails 3.1.12

Since v2.2.3

Available in: v2.2.3 v2.3.18 v3.0.20 v3.1.12 v3.2.22.5 v4.0.13 v4.1.16 v4.2.9 v5.2.8.1 v6.0.6 v6.1.7.10 v7.0.10 v7.1.6 v7.2.3 v8.0.4 v8.1.2

Compare with:

concat(string)

The preferred method of outputting text in your views is to use the <%= “text” %> eRuby syntax. The regular puts and print methods do not operate as expected in an eRuby code block. If you absolutely must output text within a non-output code block (i.e., <% %>), you can use the concat method.

Examples

<%
    concat "hello"
    # is the equivalent of <%= "hello" %>

    if logged_in
      concat "Logged in!"
    else
      concat link_to('login', :action => login)
    end
    # will either display "Logged in!" or a login link
%>

Parameters

string req
