custom field due_date with datefield plugin after upgrade to Trac 1.6

[Ales Horak]

I was running Trac 1.2 with a custom field "due_date" and the DateField plugin.

The definitions in trac.ini are:

[ticket-custom]
due_date = time
due_date.date = true
due_date.date_empty = true
due_date.format = date
due_date.label = Termín dokončení
due_date.order = 0
due_date.value = DD-MM-YYYY

[datefield]
first_day = 1
format = dmy
separator = .

This worked ok in ticket editing with correct setting in our date format as 29.10.1999.

After upgrade to Trac 1.6, the custom field works ok, but the calendar widget trac-datepicker does not follow the datefield settings and works with dates in the format of 10/29/1999, week start on Sunday.

How can I change the trac calendar widget format to the original datefield settings?

It is unable to. The date picker always determines the format based on user's locale.

I dont now is that correct for you

I set as locale in the .wsgi Script too

environ['trac.locale'] = 'de_DE.utf8'

that worked for me

thank you, I have tried setting the `environ` value, but it did not help.

finally, the problem was in the Ubuntu 24.04 Trac package, which is missing the file 

`/usr/lib/python3/dist-packages/trac/htdocs/js/jquery-ui-i18n.js`. without it, the

datepicker ignores the current locale.

I have also found out that the problem has already been reported, including

its workaround, as described in this bug report, but not fixed in this LTS version.
