我在models.py以下型號：故障排除 「相關領域具有無效查詢：icontains」
class ListinoTraduttore(models.Model):
traduttore = models.ForeignKey('Traduttore', related_name='Traduttore')
linguaDa = models.ForeignKey(Lingua, related_name = "linguaDa")
linguaA = models.ForeignKey(Lingua, related_name = "linguaA")
prezzoParola = models.CharField(max_length=50, blank=True)
prezzoRiga = models.CharField(max_length=50, blank=True)
scontoCat = models.CharField(max_length=50, blank=True)
scontoFuzzy = models.CharField(max_length=50, blank=True)
scontoRipetizioni = models.CharField(max_length=50, blank=True)
class Meta:
verbose_name_plural = "Listini Traduttori"
def __unicode__(self):
return u"%s Da %s A %s Parola=%s Riga=%s ScontoCAT=%s ScontoFuzzy=%s ScontoRipetizioni=%s" % (self.traduttore, self.linguaDa, self.linguaA, self.prezzoParola, self.prezzoRiga, self.scontoCat, self.scontoFuzzy, self.scontoRipetizioni)
class Traduttore(models.Model):
nome = models.CharField(nomeString, max_length=50)
cognome = models.CharField(cognomeString, max_length=50)
nomeAzienda = models.CharField(nomeAziendaString, max_length=50, blank=True)
codiceFiscale = models.CharField(codiceFiscaleString, max_length=50, blank=True)
partitaIva = models.CharField(partitaIvaString, max_length=50, blank=True)
indirizzo = models.CharField(indirizzoString, max_length=50, blank=True)
telefono = models.CharField(telefonoString, max_length=50, blank=True)
fax = models.CharField(faxString, max_length=50, blank=True)
email = models.EmailField(max_length=50, blank=True)
referente = models.CharField(referenteString, max_length=50, blank=True)
valuta = models.ForeignKey(Valuta)
metodoPagamento = models.ForeignKey(MetodoPagamento)
datiBancari = models.CharField(datiBancariString, max_length=50, blank=True)
programmiUtilizzati = models.ManyToManyField(Programma, blank=True)
note = models.CharField(max_length=200, blank=True)
listino = models.ManyToManyField(ListinoTraduttore, related_name='listino', blank=True)
def __unicode__(self):
return u"%s %s %s" % (self.nome, self.cognome, self.nomeAzienda)
class Meta:
verbose_name_plural = "Traduttori"
而在admin.py我有以下幾點：
class TraduttoreAdmin(admin.ModelAdmin):
list_display = ("nome", "cognome", "nomeAzienda")
search_fields = ["nome", "cognome", "nomeAzienda"]
class ListinoTraduttoreAdmin(admin.ModelAdmin):
list_display = ("traduttore", "linguaDa", "linguaA", "prezzoParola", "prezzoRiga", "scontoCat", "scontoFuzzy", "scontoRipetizioni")
search_fields = ['traduttore__nome", "linguaDa", "linguaA"]
但是，當我嘗試在ListinoTraduttore表中的管理頁面中進行搜索我有以下錯誤：

嗨，我做到了，但沒有任何變化。我有同樣的錯誤。你有什麼其他的建議？ – user1545895 2012-08-01 12:03:43
