Hello,
I have got a class Lexeme which I would like to define as follows:
class Lexeme(models.Model):
class Meta:
unique_together = ((u"entity", u"language"),)
language = models.ForeignKey(Language)
# ...
I would like to have different types of lexemes, each of which has
another field type as "entity". Like so:
class CommodityLexeme(Lexeme):
class Meta:
verbose_name_plural = "Commodities"
entity = models.ForeignKey(Commodity)
class CountryLexeme(Lexeme):
class Meta:
verbose_name_plural = "Countries"
entity = models.ForeignKey(Country)
I know this doesn't work, because field name hiding is not permitted.
(See
https://docs.djangoproject.com/en/1.1/topics/db/models/#field-name-hiding-is-not-permitted).
But what would be the most elegant workaround? I suppose someone has
had a similar problem before.
Jaroslav
