This is an easily customizable time_ago_in_words implementation in Swedish that will produce this output:

   1  < 5 minuter
   2  < 45 minuter
   3  < 1 timme
   4  > 2 timmar
   5  > 1 dag, 2 timmar
   6  20 April 2010 (if more than 31 days ago)

The code:

   1  class Time
   2    def time_ago_in_words
   3      words = ''
   4      timestamp = self
   5      if timestamp
   6        time_until = (Time.now.to_datetime - timestamp.to_datetime)
   7        days = time_until.to_i
   8        hours, minutes, seconds, frac = Date.day_fraction_to_time(time_until)
   9        hours = hours % 24
  10  
  11        if days == 0
  12          if hours < 1
  13            words = case minutes
  14              when 0..4 then "< 5 minuter"
  15              when 5..14 then "< 15 minuter"
  16              when 15..29 then "< 30 minuter"
  17              when 30..44 then "< 45 minuter"
  18              when 45..59 then "< 1 timme"
  19            end
  20          else
  21            words = "> #{hours} #{'timme'.inflect(hours)}"
  22          end
  23        elsif days < 31
  24          words = "> #{days} #{'dag'.inflect(days)}"
  25          if hours > 0
  26            words += ", #{hours} #{'timme'.inflect(hours)}"
  27          end
  28        else
  29          words = timestamp.l(:format => :daymonthyear)
  30        end
  31      end
  32      words
  33    end
  34  end

You’ll need this for inflections:

   1  class String
   2    def inflect(count)
   3      count > 1 ? ActiveSupport::Inflector.pluralize(self) : self
   4    end
   5  end

Add this to config/locales/sv-SE.yml for localizing the date in Swedish:

   1  time:
   2      formats:
   3        daymonthyear: "%d %B %Y"

Add this to config/initializers/inflections.rb for Swedish inflections:

   1  ActiveSupport::Inflector.inflections do |inflect|
   2    inflect.irregular 'dag', 'dagar'
   3    inflect.irregular 'vecka', 'veckor'
   4    inflect.irregular 'månad', 'månader'
   5    inflect.irregular 'timme', 'timmar'
   6    inflect.irregular 'minut', 'minuter'
   7    inflect.irregular 'sekund', 'sekunder'
   8  end

The code:

   1  class Delicious
   2    class << self
   3      def tag(username, name, count = 15)
   4        links = []
   5        url = "http://feeds.delicious.com/v2/rss/#{username}/#{name}?count=#{count}"
   6        feed = Hpricot(open(url))
   7  
   8        feed.search("item").each do |i|
   9          item = OpenStruct.new
  10          item.link = i.at('link').next.to_s
  11          item.title = i.at('title').innerHTML
  12          item.description  = i.at('description').innerHTML rescue nil
  13  
  14          links << item
  15        end
  16  
  17        links
  18      end
  19    end
  20  end

Usage:

   1  # Return last 15 items tagged with business and news from jebus's account:
   2  Delicious.tag 'jebus', 'business+news', 15

Returns an array of items.

I’m using the mail gem and received this error when sending emails:

   1  530 5.7.0 Must issue a STARTTLS command first

The fix was to first install the tlsmail gem:

   1  gem install tlsmail

Then I had to add this to config/initializers/email.rb:

   1  require 'tlsmail' 
   2  Net::SMTP.enable_tls(OpenSSL::SSL::VERIFY_NONE)

This will give the variable “something” a value of “nothing” if it’s not defined:

   1  <%
   2    something = 'nothing' if local_assigns.has_key? :something
   3  %>

   1  class Time
   2    def until_in_words
   3        words = ''
   4        if self
   5          time_until = (self.to_datetime - Time.now.to_datetime)
   6          days = time_until.to_i
   7          if days == 0
   8            hours, minutes, seconds, frac = Date.day_fraction_to_time(time_until)
   9            words += %Q{<span class="number">#{hours.abs}</span> h}
  10            words += %Q{<span class="number"> #{minutes.abs}</span> min}
  11            words += %Q{<span class="number"> #{seconds.abs}</span> sec}
  12  
  13            if time_until.to_f < 0
  14              words += " ago" 
  15            else
  16              words = "in " + words
  17            end
  18          else
  19            words = %Q{<span class="number">#{days.abs}</span> } + "day".p(days.abs)
  20  
  21            if days < 0
  22              words += " ago" 
  23            else
  24              words = "in " + words
  25            end
  26          end
  27  
  28        end
  29        words
  30      end
  31    end
  32  end

This will give you, for example, the following:

• in 1684 days
• 3794 days ago
• 1 day ago
• 22 h 12 min 6 sec ago
