<%x=@late_commers.split(“,”)%>
<% x.each do |late_commer| %>

<%= late_commer.at(0) %> <%end%>

This works for me. No need to declare x as Array.new… that’s going
to happen when you assign it the value of late_commers.split

Why the late_commer.at(0) if late_commer is the value of an individual
string? Are you sure that late_commers is a string to begin with?

irb(main):001:0> x = “This, is, a, test”
=> “This, is, a, test”
irb(main):002:0> y = x.split(“,”)
=> [“This”, " is", " a", " test"]
irb(main):003:0> y.each do |z|
irb(main):004:1* puts z
irb(main):005:1> end
This
is
a
test
=> [“This”, " is", " a", " test"]
irb(main):006:0>

honey ruby, c’mon… Did you know about such things like controllers?
Passing whole work with arrays in views it’s a bad idea.

app/controllers/my_controller.rb

class MyController < ApplicationController
def commers
@late_commers = “Khamar Md,2 hrs: 5
min,Accounts,Gandhinagar”.split(",")
end
end

app/views/my/commers.html.erb

…

.. <% @late_commers.each do |late_commer| %> <%end%> ..
<%= late_commer %>
..

No need to declare x as Array.new.
You’re right. There is no need to declare it case split returning an
array.

Why the late_commer.at(0) if late_commer is the value of an individual
string? Are you sure that late_commers is a string to begin with?
Greg, +1
honey, you’re trying to get each item(that is a string object in this
case) from array.
And it doesn’t have such method like ‘at’
