ciao, ho un modello in django con una relazione manytomany su se stesso. ora pero' non riesco a fare una banale select.
class Word(models.Model):
word = models.CharField(maxlength=50)
language = models.ForeignKey(Language)
translations = models.ManyToManyField("self", blank=True)
def __str__(self):
return self.word
>>> Word.objects.get(word='ciao')
DoesNotExist:.....
e invece esiste...
>>> Word.objects.get(word__contains='ciao')
TypeError: Related Field has invalid lookup: contains
>>> Word.objects.all().filter(word='ciao')
[]
avete qualche idea?
ciao
m.
