The output from my hash is giving me the following date time:
16 May 11 13:12:14 +0000
How do I go about formatting this into something sensible?
Thanks
I'll assume you are wanting this output in a view... First, you can create some formats:
# /config/locales/en.yml:
en:
date:
formats:
full: "%b %d, %Y"
time:
formats:
full: "%B %d, %Y at %I:%M%p"
Then you can display a datetime in a view using the l method with specified format:
<%= l #something.updated_at, :format => :full %>
This would display something like the following:
May 16, 2011 at 01:12pm

I'm using the format below to display my time ago but need help understanding how to do the format for the default date format. Using rails-timeago gem:
=timeago_tag Time.zone.now, :nojs => true, :limit => 2.days.ago, lang: :en
print>> 2d
After that it does the yyyy-dd-mm format.
I would like to format the default date like May 22, 2014. There's a (:strftime,'%B %d, %Y') that I've used in other format to display how I wanted it but I'm not sure how the syntax works with the timeago_tag helper.
As we discussed in the comments, timeago_tag has a format option, so to get your date in the format "%B %d, %Y":
= timeago_tag Time.zone.now, nojs: true, limit: 2.days.ago, lang: :en, format: "%B %d, %Y"
I've got a strange problem with date translations in my Ruby On Rails 3 application, and I really don't understand why...
Here are my en.yml and fr.yml :
fr:
date:
formats:
default: "%d/%m/%Y"
short: "%e %b"
long: "%e %B %Y"
time:
formats:
default: "%d %B %Y %H:%M:%S"
short: "%d %b %H:%M"
long: "%A %d %B %Y %H:%M"
am: 'am'
pm: 'pm'
en:
date:
formats:
default: "%Y-%m-%d"
long: "%B %d, %Y"
short: "%b %d"
time:
am: am
formats:
default: ! '%a, %d %b %Y %H:%M:%S %z'
long: ! '%B %d, %Y %H:%M'
short: ! '%d %b %H:%M'
pm: pm
This is not specific to a particuliar view, but for instance in one of my view :
<td><%=l job_application.created_at, :format => :default %></td>
I get those strange outputs :
With locale = :en
=> t, 30 o 2012 18:09:33 +0000
With locale = :fr
=> 30 o 2012 18:09:33
Where do these wrong "formats" come from ?
I'm using Rails 3.2.8 (with Postgresql / gem pg), and everything related to I18n works fine except for dates.
Thanks for any help !
I think I've finally figured this out, sorry for taking so long.
The Rails l helper just calls I18n.localize. If you trace through the I18n.localize code, you'll end up here:
format = format.to_s.gsub(/%[aAbBp]/) do |match|
case match
when '%a' then I18n.t(:"date.abbr_day_names", :locale => locale, :format => format)[object.wday]
when '%A' then I18n.t(:"date.day_names", :locale => locale, :format => format)[object.wday]
when '%b' then I18n.t(:"date.abbr_month_names", :locale => locale, :format => format)[object.mon]
when '%B' then I18n.t(:"date.month_names", :locale => locale, :format => format)[object.mon]
when '%p' then I18n.t(:"time.#{object.hour < 12 ? :am : :pm}", :locale => locale, :format => format) if object.respond_to? :hour
end
end
So the localize helper doesn't use strftime for the "stringy" parts of the date/time, it tries to do it by itself. Add the translations (as arrays in your YAML) for the month and day names as above and your localized dates and times should start working.
If you don't have those translation arrays in your YAML, then I18n.t(:"date.abbr_month_names") will give you strings like this:
"translation missing: en.date.abbr_month_names"
and then I18n.localize will end up doing silly things like this:
"translation missing: en.date.abbr_month_names"[10]
That will use String#[] instead of the expected Array#[] and you end up with random looking single character month and day names.

Because created_at is a DateTime, rails using time formats (not date).
https://github.com/svenfuchs/rails-i18n/blob/master/rails/locale/en.yml#L195
time:
am: am
formats:
default: ! '%a, %d %b %Y %H:%M:%S %z'
Type in your console
I18n.t(:"date")
to check if you are getting the translations you defined in your translation .yml file.
Compare the structure with the standard EN locale
I18n.t(:"date", locale:'en')
That made me notice I was declaring the date: attribute twice in my .yml, and the first part was being overwritten by the second declaration.
You should get the abbr_month_names that you declared when calling
I18n.t(:"date.abbr_month_names")
These are the ones that will be used when calling %b.
If not, check your locale .yml file to make sure they are properly declared, and not being declared twice.
You may also call I18n.locale to check if the .yml file you are editing is the one being used by rails

I am using Ruby on Rails v3.2.2 and I would like to display a data as-like <day_number> <month_name> <year_number>. That is, I have a datetime database table column and I would like to change its contained values, for example, from 2012-04-27 00:00:00 to 27 april 2012.
How can I make that?
The standard way is use rails localization.
model
I18n.l(datetime, :format => :short)
controller
I18n.l(datetime, :format => :long)
view
<%= l(datetime), :format => :custom %>
config/locales/en.yml
en:
time:
formats:
long: "%A %B %d %Y | %I:%M %p GMT"
short: "%d %B %Y, %H:%M GMT"
custom: "your custom format"
date:
formats:
short: "%d %B %Y"
long: "%A %B %d %Y"
custom: "your custom format"
In your case the format should be "%d %A %Y".
The benefit is if you want to change format you can do it in one place for all datetimes which you are using.
You can use the method
str_name.strftime("%d %A %Y")
I have my default locale set in the environment.rb as de (German).
I also see all the error messages in German, so the locale is picked up by the server. But when I try to print date with strftime like following:
some_date.strftime('%B, %y')
It prints in English (January, 11), and not the expected German (Januar, 11).
How can I print the date according to the default locale?
Use the l (alias for localize) method instead of raw strftime, like this:
l(date, format: '%B %d, in the year %Y')
See here for more information.
You can also define 'named' formats, a couple of them (short, long) are already predefined.
you can also make it shorter:
l(some_date, :format => '%d %B %Y')
In es.yml put:
es:
date:
formats:
default: "%d / %m / %Y"
In index.html.erb put:
<%= l somemodel.datefield %>
