我很难将一个formset保存到数据库中.我有两个模型,一个有一个ForeignKey到另一个(我在Django管理页面中为Balanta模型做了一些条目):

models.py

    class Balanta(models.Model):
    data=models.DateField()

    class Meta:
        ordering=['data']
        verbose_name_plural="Balante"

    def __unicode__(self):
        return unicode(self.data)


class Conturi(models.Model):
    cont=models.PositiveIntegerField()
    cont_debit=models.DecimalField(default=0, max_digits=30, decimal_places=2)
    cont_credit=models.DecimalField(default=0, max_digits=30, decimal_places=2)
    balanta=models.ForeignKey(Balanta)

    class Meta:
        #ordering=['cont']
        verbose_name_plural="Conturi"

    def __unicode__(self):
        return unicode(self.cont)

接下来我做了一个forms.py:

from sitfin.models import Conturi, Balanta
from django.forms import ModelForm

class BalantaForm(ModelForm):
    class Meta:
        model=Balanta

class ConturiForm(ModelForm):
    class Meta:
        model=Conturi

和views.py:

from django.http import HttpResponseRedirect
from django.shortcuts import get_object_or_404, render_to_response
from django.template import RequestContext
from sitfin.models import Balanta, Conturi
from sitfin.forms import BalantaForm, ConturiForm
from …
