• Lino-Welfare: Miscellaneous translations. Added explicit blank=True to ChoiceList fields where necessary.

    “jobs.Contract [u’Datumsbereich 01.12.2011…31.12.2011 auxdferhalb Begleitungsperiode 01.08.2012….’] (1 object(s) with primary key 180)”

  • Added i18n support (locale dirs) for modules lino.modlib.accounts and lino.modlib.ledger.

  • New feature: Lino now supports writing dummy modules. A little change in lino.core.modeltools.resolve_app(), and a first example lino.modlib.postings.dummy used in lino_xl.lib.cal.

  • New test application lino.test_apps.quantityfield.

    QuantityFields are implemented as CharFields and therefore should not be declared null=True. The message “Nullable CharField %s in %s” % (f.name,model) produced by lino.core.kernel.analyze_models() is now again a plain Exception.

    But if blank=True, empty strings are converted to None values.

  • VoucherTypes caused problems because it had no blank_item:

    Unresolved value '' for <class 'lino.modlib.ledger.models.VoucherTypes'>

        response = callback(request, *callback_args, **callback_kwargs)

        obj.__dict__[self.field.name] = self.field.to_python(value)
      File "t:\hgwork\lino\lino\utils\choicelists.py", line 462, in to_python
        return self.choicelist.to_python(value)
      File "t:\hgwork\lino\lino\utils\choicelists.py", line 328, in to_python
        raise Exception("Unresolved value %r for %s" % (value,cls))

    I completely removed the blank_item from ChoiceList and replaced it by None. My feeling (had already been saying before that this blank_item was a strange thing). But not yet sure whether there will be surprises…
