i am trying to make my code more dry and neat hence i used following in my "config/enviornment.rb":
Time::DATE_FORMATS[:default] = "%d/%M/%y"
But not saw any change in date format.Then i try "strftime" method but it doesn't suit my code.Please guide me on some better option .Thanks in advance
You can use the I18n for that.
config/locales/en.yml:
en:
date:
formats:
default: "%d/%M/%y"
short: "%b %d"
long: "%B %d, %Y"
Then use I18n.l Time.now (or <%= l Time.now %>in your views).
EDIT: To specify the format, use <%= l Time.now, :format => :short %>

I am getting an error with strftime.
My views look like:
<%=room.date%> which works and yields "2017-07-27".
However, I want to convert this to "July 27, 2017".
<%= Date.parse(room.date).strftime("%B %e, %Y ") %> does not work and causes the following error:
ActionView::Template::Error (no implicit conversion of Date into
String)
My schema is:
t.date "date"
I don't know what I am doing wrong. Thanks!
If your room.date is type of date you shouldn't try to parse it. So I'd suggest first try to use <%= room.date.strftime('%B %e, %Y'). Please comment below if that wont work.
Just to throw a different hat into the ring, you can also use
<%= l room.date, format: :long %>
which, by default, uses "%B %d, %Y" but can be easily changed by adding into your config/locales/en.yml.
en:
date:
formats:
long: "%B %e, %Y"
time:
formats:
long: "%B %e, %Y"
Use date: if it's a Date object or time: if it's DateTime or Time. This is short for I18n.l and looks like it works as far back a rails 3.2.13 at the least (it's hard to tell which rails you're using).
This way, if you ever want to support different locales the dates are all set up for it and, probably more importantly, it moves the date format out of your views, so if you ever decide you want a different format ("%A %B %e, %Y", for instance) you can change it in one place and all the views displaying dates get updated.
Note: If it is a Time or DateTime you might want to use instead
<%= l room.date, format: :date %>
and in config/locales/en.yml
en:
time:
formats:
date: "%B %e, %Y"
so your format: :long still shows the time portion when you want it to
It's asking for a String instead a Date data type, pass it a String, try with:
Date.parse(room.date.to_s).strftime("%B %e, %Y")
When room.date is a date, why do you want to parse it? You could use the Date directly.
Can you try:
<%= room.date.strftime("%B %e, %Y ") %>
Is there anyway in ruby on rails to convert this date 2014-08-13T22:11:18.138Z into a more readable format such as dd/mm/yyyy or jan 1st 2014.
It's from a createdAt field of a parse.com database.
How do I convert this?
Would I need some type of regex?
Is there built in ruby code I can use to do the conversion for me?
You could do with:
// it will be parsed to the datetime in the timezone configured by rails app.
Time.zone.parse('2014-08-13T22:11:18.138Z').strftime('%d/%m/%Y')
The Date class has a whole lot of built in conversions for standard formats. Identify the format ( in this case RFC3339 ) and you will be able to find something like this:
require 'date'
return Date.rfc3339('2014-08-13T22:11:18.138Z')
#<Date: 2014-08-13 ((2456883j,0s,0n),+0s,2299161j)>
In your locale en.yml
date:
formats:
# Use the strftime parameters for formats.
# When no format has been given, it uses default.
# You can provide other formats here if you like!
default: "%d/%m/%Y"
short: "%b %d"
long: "%B %d, %Y"
in your view
<%= I18n.l #entry.created_at, :format => :short %>
Each user of our application can have different format for Date.
I can use something like this Date::DATE_FORMATS[:default] = "%m/%d/%Y" in the application controller for changing by default date formatting.
But i want to change date formats in the en.yml to:
date:
formats:
default: "%Y/%m/%d"
short: "%b %d"
long: "%B %d, %Y"
How can i change default, short and long date formates in yml file on the fly as we can use Date::DATE_FORMATS[:default] = "%m/%d/%Y".
Note: in view i use <%= l Time.now.to_date, :format=>:short%>
Thanks.
You can use in application controller only with different data format.
write in application controller.
Time::DATE_FORMATS.merge!(:data_format => "%d-%B-%Y")
Time::DATE_FORMATS.merge!(:data_format_month => "%m-%d-%Y")
and in view or helper call data_format or data_format_month.
example
created_on.to_s(:data_format) for displaying D-B-Y format
update_on.to_s(:data_format_month ) for displaying M-D-Y format
I keep having to append ".strftime("%H:%M")" to anything that is displaying a time in my Rails project. I have a start time and an end time for each Concert object, so I have to append ".strftime("%H:%M")" whenever I wanna display those times.
Note that I'm not asking to change the date format. The date looks fine as it is (as MM/DD/YYYY).
What's the best way to get around this? Is there a way to set the default time format?
(I'm pretty sure this is only a Ruby thing, but I'm a newbie, so I'm not sure.)
Since you're using Rails, take advantage of the I18n support: http://guides.rubyonrails.org/i18n.html#adding-date-time-formats
# config/locales/en.yml
en:
time:
formats:
default: "%H:%M"
Then when you call I18n.l Time.now or <%= l Time.now %>, it'll use that format automatically.
Ruby on Rails has built-in presets for formatting Date and Time instances. Here's what they are for Time on my machine:
>> Time::DATE_FORMATS
=> {:short=>"%d %b %H:%M", :db=>"%Y-%m-%d %H:%M:%S", :rfc822=>#<Proc:0x0000000103700b08#/Users/donovan/.gem/gems/activesupport-3.0.1/lib/active_support/core_ext/time/conversions.rb:13>, :time=>"%H:%M", :number=>"%Y%m%d%H%M%S", :long_ordinal=>#<Proc:0x0000000103700e50#/Users/donovan/.gem/gems/activesupport-3.0.1/lib/active_support/core_ext/time/conversions.rb:12>, :long=>"%B %d, %Y %H:%M"}
You can easily use them like so:
>> Time.now.to_s(:db)
=> "2011-01-12 15:26:11"
You can define your own and use it, too:
>> Time::DATE_FORMATS[:mine] = "%H:%M"
=> "%H:%M"
>> Time.now.to_s(:mine)
=> "15:28"
You could create a custom function in your application_helper.rb file. Maybe something like:
def custom_time(date)
date.strftime("%H:%M")
end
Not sure if this is best practice but it should work well.
I use an initializer: config/initializers/time_formats.rb which contains:
[Time, Date].map do |klass|
klass::DATE_FORMATS[:app_date] = "%m/%d/%Y"
klass::DATE_FORMATS[:app_month_and_year] = "%B %Y"
klass::DATE_FORMATS[:app_abbrev_month_and_year] = "%b %Y"
...
end
Then I use Time.now.to_s(:app_date), etc based on how I want to display it.
You could add Time::DATE_FORMATS[:default] = "%H:%M" to accomplish what you're trying to do. This is not internationalized though - for that, coreyward's answer is probably better.
My field:
<%= f.text_field :expires_at, :label => false, :class => "input-field" %>
but I want the date to be kinda like this when the page loads: June, 1st, 1752 9:54:00 pm
How would I do that?
Why are you using a text_field for a datetime? Consider using time_select instead.
If you really want to format a date that way though, just use strftime.
So, in your case, add
:value => #object.expires_at.strftime('%B %d, %Y %H:%M:%S %p')
You can format dates and times using the strftime method.
See Ruby's strftime and then use :value => #date_value
If you want this date format to be used throughout your application, you can set the default format in your environment.rb file:
ActiveSupport::CoreExtensions::Time::Conversions::DATE_FORMATS.merge!(:default => "%a %m/%d/%Y %I:%M%p")
If you do this, every time you display a date, it will be formatted according to the date format string you've provided.
