Comment:
Thanks for this ticket, however it works for me with MariaDB, MySQL, and
other built-in backends (I checked with Django 3.0, 3.1, 3.2, 4.0, 4.1,
and on the current `main` branch)
{{{
--
-- Create constraint sample_othermodel_firstname on model othermodel
--
ALTER TABLE `sample_othermodel` ADD CONSTRAINT
`sample_othermodel_firstname` CHECK (`firstname` = '');
}}}
