Question

我需要使用shell将发票明细的元素添加到inlineformset_factory，我的模型是：

class InvoiceDetail(CreateUpdateMixin):
    client = models.ForeignKey('client.Client', verbose_name=_('Factura A'), blank=True, null=True, default=None)
    date = models.DateField()
    tax = models.FloatField()
    concept = models.ForeignKey(ConceptDetail, null=True, blank=True, verbose_name=_('Clave Concepto'))
    custom_concept = models.CharField(max_length=150, null=True, blank=True, verbose_name=_('Concepto'))
    amount = models.IntegerField(verbose_name=_('Cantidad'))
    fee = models.FloatField(verbose_name=_('Honorarios')) 
    duty = models.FloatField(verbose_name=_('Gastos'))  
    invoice = models.ForeignKey(Invoice, null=True, blank=True, related_name='detail_concepts')

class Invoice(CreateUpdateMixin):
    invoice = models.CharField(max_length=15, verbose_name=_('Número de Factura'))
    # Details to show when calls the invoice choice from menu in procedure
    # for mabe is an addenda
    title_addenda = models.CharField(max_length=80, verbose_name=_('Titulo Detalle Factura'))
    detail_addenda = models.CharField(max_length=350, verbose_name=_('Detalle Factura'))
    status = models.ForeignKey(StatusInvoice, null=True, blank=True)

我试过了，但没有用

In [54]: invoice_obj = Invoice.objects.get(invoice=100067)
Out[55]: <Invoice: 100067>
In [56]: inv_det = InvoiceDetail.objects.get(custom_concept='PROFESSIONAL FEES FOR THE PAYMENT OFEACH ANNUAL TAX ON PATENTS')
Out[57]: <InvoiceDetail: b'PROFESSIONAL FEES FOR THE PAYMENT OFEACH ANNUAL TAX ON PATENTS'>
In [58]: # create inlineformset_factory
In [59]: TestFormSet = inlineformset_factory(Invoice, InvoiceDetail, fields='__all__')

In [61]: test = TestFormSet(instance=invoice_obj)

In [62]: test.data
Out[62]: {}
In [63]: test.save()
Out[63]: []

我尝试按照django docs inline-formsets按照我的步骤正确的文档进行操作，我做错了吗？

已修改以添加更多详细信息

我有一个迁移脚本，我需要在Invoice中添加多个InvoiceDetail对象，因此我尝试转换为inlineformset_factory，认为这是正确的方法，但我不知道，如果直接添加InvoiceDetail到发票它没有维护所有InvoiceDetail它只保留最新，如果我修改我的模型发票到m2m InvoiceDetails我可以保留所有元素但我不能使用formset.all InvoiceDetail它只保留最新的。< / p>

这是我的脚本代码：

def _get_invoice_detail(self, key, complex_dictionary):
    """
        For add correct data we need to create a formset so.
    :param complex_dictionary:
    :return:
    """
    # from django.forms.models import inlineformset_factory
    # InvoiceDetailFormSet = inlineformset_factory(Invoice, InvoiceDetail, fields='__all__')
    # load all invoices from db
    _db = {}
    _concept = {}
    obj = None
    clase = None
    for i in Invoice.objects.all():
        _db[i.invoice] = i
    res = {}
    for i in ConceptDetail.objects.all():
        _concept[i.pk] = i        
    for i in complex_dictionary:
            try:
                if int(i['CCLAVE']) in self.clients:
                    _client = self.clients[int(i['CCLAVE'])]
                _client = Client.objects.get(pk=int(i['CCLAVE']))
