Custom date format

Rails
1

Hi, I’ve followed these directions :
http://railswiki.pdxruby.org/HowToDefineYourOwnDateFormat.html

It seems pretty straightforward but obviously it doesn’t work for me…
article.date_edited.to_formatted_s(:my_format_1)

produce a default formatted date, not the one I’ve defined in
environment.rb :
ActiveSupport::CoreExtensions::date::Conversions::DATE_FORMATS.merge!(
:my_format_1 => ‘%d/%m/%Y - %H:%M’,
:my_format_2 => ‘%l:%M %p, %B %d, %Y’
)

What’s wrong ?

Thanks

What does “it doesn’t work for me” mean?

I’m doing this and it works fine. Just make sure the format definitions
in your environment.rb go outside the run block.

By the way, you can just use some_date.to_s(:format) - Date#to_s is
aliased to Date#to_formatted_s

It means that my_format_1 has no effect at all when used with
to_formatted_s, Rails displays the default date format instead.

Thank for the hint Josh,

I’m working on a Rails Engine and I wonder how it could be related with
the problem ? I really don’t understand…

Just to be sure, here is the content of the files again :

environment.rb :
ActiveSupport::CoreExtensions::date::Conversions::DATE_FORMATS.merge!(
:my_format_1 => ‘%d/%m/%Y - %H:%M’,
:my_format_2 => ‘%l:%M %p, %B %d, %Y’
)

the view - list.rhtml
<%= article.date_edited.to_s(:my_format_1) %>

I’ve tried with the console and everything is ok :
my_format_1 is listed and Date.today.to_s(:my_format_1) returns a date
formatted accordingly to the format…

The record in the db does contain a date value and trying different
formats (eg. :short) works fine in the view

I really don’t understand…

But at least I’m learning about the console ! Great tool !

That looks to me like it should work. I suggest checking things out in
the console. Go in script/console and examine
ActiveSupport::CoreExtensions::date::Conversions::DATE_FORMATS to make
sure your format additions worked, then try printing
Date.today.to_s(:my_format_1). Also, look in the database and make sure
there is a date in the field, try printing it with a different format,
etc.

Last thing I can think of is to quit and restart your server. I think
you have to do that to get changes in the environment.rb to load.
