Hi ruby community,

I use ruby 1.8.6, rails 2.2.2 and mysql 5.045.

In my scaffold I use "t.date :birthday".

When I want to save a birthday  like 12.05.1970 I can save it. But when
I try to save older birthdays like 12.05.1969 I get the error-message
"time out of range".

Remarkable is, when I try to save the date without ruby/rails directly
in the mysl-database, there is no error-message, so it must be a kin of
ruby/rails bug.

Do somebody know a solution?

Thanks in front for every proposal for solution:-)

Dates can't store earlier than I think 1970 something. Use time.

Can you print the entire error message and stack trace, if any?

I just tried this on the same setup and had no error.

The MySQL Date doc for 5.0.x says:

The DATE type is used when you need only a date value, without a time
part. MySQL retrieves and displays DATE values in 'YYYY-MM-DD' format.
The supported range is '1000-01-01' to '9999-12-31'.

FYI,

Thanks for all suggestions!

I made a little date experiment and the normal date range of ruby 1.8.6,
rails 2.2.2 and mysql 5.045 is between 01.01.0001 and 01.01.3000 or
greater.

The error message "argument out of range" appears only when I use the
DHTMLCalendar plugin from

ruby script/plugin install
http://dhtml-calendar.googlecode.com/svn/trunk

The first two lines of the Application-Trace

vendor/plugins/svn/lib/extensions/active_record.rb:61:in `local'
vendor/plugins/svn/lib/extensions/active_record.rb:61:in `quote'

are pointing to a fault in the active_record.rb of the
DHTMLCalendar-plugin:

Line 61:  when Date then "'#{quoted_date(Time.local(value.year,
value.month, value.day, 0, 0, 0))}'"
        else            quote_without_date_cast(value, column)

Do somebody knows a solution?

Thanks in front.

While the ruby Date class has an absolutely massive range, Time
doesn't, so the plugin shouldn't really be converting a date instance
into a instance of Time (at least not without checking if it is
possible first)
