How to show current year in view?
Ruby on-RailsRuby on-Rails-3Ruby on-Rails Problem Overview
Is there a function I can use to show the current year in a view? I have tried
<%= Time.now %>
to try and show the time but this does not work for me.
Ruby on-Rails Solutions
Solution 1 - Ruby on-Rails
<%= Time.current.year %>
Solution 2 - Ruby on-Rails
I'd rather use Date class to get year than Time class (if you only need the Date, you don't need to consider hours, minutes and seconds).
<%= Date.today.year %>
c.f. http://ruby-doc.org/stdlib-2.1.0/libdoc/date/rdoc/Date.html#method-c-today
Solution 3 - Ruby on-Rails
I think the best way to get the current year considering application timezone is:
Date.current.year
Solution 4 - Ruby on-Rails
I like to use:
Time.zone.now.year
This takes into account the current timezone (incase you have overridden it for a particular user).
Solution 5 - Ruby on-Rails
Despite that it has already been answered, I thought it might come handy for those who want to look at benchmark results for all the suggested solutions.
require 'benchmark'
n = 500000
Benchmark.bm do |x|
x.report { n.times do ; Date.today.year; end }
x.report { n.times do ; Date.current.year; end }
x.report { n.times do ; Time.current.year; end }
x.report { n.times do ; Time.zone.now.year; end }
end
user system total real
0.680000 0.030000 0.710000 ( 0.709078)
2.730000 0.010000 2.740000 ( 2.735085)
3.340000 0.010000 3.350000 ( 3.363586)
3.070000 0.000000 3.070000 ( 3.082388)
Now, it may perhaps seem over the top for something as simple as that, however, from a simple optimisation perspective for a high throughput application, I will consider using Date.today.year
Said so, if your application is Time Zone sensitive, perhaps Date.current or Time.zone based methods are your best bet.
