Question

I have a controller:

class StatsController < ApplicationController

  require 'time'

  def index
      @started = "Thu Feb 04 16:12:09 UTC 2010"
      @finished = "Thu Feb 04 16:13:44 UTC 2010"
      @duration_time = stats_duration(@started, @finished)
  end

  private
  def stats_duration(started, finished)
    time_taken = distance_of_time_in_words(Time.parse(started), Time.parse(finished))
    time_taken
  end

end

It takes in a start and end time and calculates the duration between the times.

When I run this I get the following error:

private method `gsub!’ called for Thu
Feb 04 16:12:09 UTC 2010:Time

Why is this happening?

Answer 1

private method gsub! called when using Time.parse usually means that you have called parse with a Time object rather than a String so it sounds like your code is actually trying to parse the time twice.

e.g.

>> t = Time.now
=> Fri Feb 05 13:12:17 +0000 2010
>> Time.parse(t)
