Hi RoR community,

for my webapp I need the german date format.

To display the german date format like 31.12.2009, I implemented in the  
environment.rb following:

ActiveSupport::CoreExtensions:📅:Conversions::DATE\_FORMATS.merge!(  
:default =\> ’ %d.%m.%Y ’  
)

If I use the DhtmlCalendarHelper “calendar\_field” the date in edit-mode  
is diplayed in german date-format, like 21.11.1990.

If I use the DhtmlCalendarHelper “calendar\_box” the date in edit-mode  
falls back to american date-format, like 1990-11-21.

Do somebody knows why?

Thanks ahead for every answer!

Regs,

hermann
