Django提交复制表格

Question

嗨，大家好，我对表单有疑问。我有两个模型，其中一个模型在不同模型上有3个相关的ForeignKeys。在下面的例子中将显示代码。 问题是第一种形式是submited好的，并插入数据库的作品。但下一个表格不会提交。不知道我做错了什么。

模型

class OutgoingInvoice(models.Model): 
    id = models.AutoField(primary_key=True) 
    invoice_number = models.IntegerField() 
    date = models.DateField() 
    time = models.TimeField() 
    place = models.CharField(max_length=255) 
    status = models.CharField(max_length=255) 
    due_date = models.DateField() 
    total_invoice_amount = models.DecimalField(decimal_places=5, max_digits=255) 
    vat_amount = models.DecimalField(decimal_places=5, max_digits=255) 
    invoice_amount = models.DecimalField(decimal_places=5, max_digits=255) 
    discount = models.DecimalField(decimal_places=5, max_digits=255) 
    user_id = models.ForeignKey('IzibiziUser') 
    organization_id = models.ForeignKey('IzibiziOrganization') 
    customer_id = models.ForeignKey('OrganizationInfo') 

    def __str__(self): 
     return str(self.id) 

形式

class InsertNewCustomer(forms.ModelForm): 
    name  = forms.RegexField(regex=r'\w+', label=_('Klijent'),widget = forms.TextInput({'class':'form-control', 'placeholder':'Klijent'})) 
    oib   = forms.RegexField(regex=r'\d.+', label=_('OIB'),widget = forms.TextInput({'class':'form-control', 'placeholder':'OIB'})) 
    address  = forms.RegexField(regex=r'\w+', label=_('Adresa'), widget = forms.TextInput({'class':'form-control', 'placeholder':'Adresa'}))

    @property 
    def clean_form(self): 
     try: 
      obj = OrganizationInfo.object.get(oib__iexact=self.cleaned_data['oib']) 
     except OrganizationInfo.DoesNotExist: 
      return self.clean_form 

    class Meta: 
     model = OrganizationInfo 
     fields = ('name', 'oib', 'address', 'city', 'postal_code',) 
     exclude = (
      'country', 'phone', 'email', 'iban', 'webpage', 'delivery_address', 'delivery_city', 'delivery_postal_code', 
      'delivery_country',) 


class OutNewInovice(forms.ModelForm): 
    date   = forms.RegexField(regex=r'\w+', label=_('Datum računa'), widget = forms.TextInput({'class':'form-control date-now', 'placeholder':'Datum računa'})) 
    due_date  = forms.DateField(label=_('Datum dospjeća'), widget = forms.TextInput({'class':'form-control', 'placeholder':'Datum dospjeća'})) 
    time   = forms.RegexField(regex=r'\w+', label=_('Vrijeme'), widget = forms.TextInput({'class':'form-control time-now', 'placeholder':'Vrijeme'})) 
    status   = forms.ChoiceField(widget = forms.Select(),choices = ([('1','Neplaćeno'), ('2','Plaćeno')]), initial='1', required = True,) 
    place   = forms.RegexField(regex=r'\w+', label=_('Mjesto'), widget = forms.TextInput({'class':'form-control', 'placeholder':'Mjesto'})) 
    invoice_number = forms.RegexField(regex=r'\w+', label=_('Broj računa'), widget = forms.TextInput({'class':'form-control', 'placeholder':'Broj računa'})) 


    status.widget.attrs['class'] = 'selectpicker' 
    status.widget.attrs['style'] = 'width:100%;' 

    @property 
    def clean_form(self): 
     try: 
      obj = OutgoingInvoice.object.get(status__iexact=self.cleaned_data['status']) 
     except OrganizationInfo.DoesNotExist: 
      return self.clean_form 


    class Meta: 
     model = OutgoingInvoice 

     fields = ('date', 'due_date', 'time', 'status', 'place', 'invoice_number',) 
     exclude = ('total_invoice_amount', 'vat_amount', 'vat_amount', 'invoice_amount', 'discount',)

    variables = RequestContext(request, {

     'new_customer': new_customer, 
     'new_inovce': new_inovce, 
    }) 

    return render_to_response(template, variables) 

如果不需经过看到我做错了。表单提交时，我没有在窗体上发生任何错误。

Answer 1

在对数据执行任何操作之前，您需要检查两个表单是否有效，如果两个表单都有效，则只需重定向。这：

if new_customer.is_valid(): 
     a = new_customer.save() 

     if new_inovce.is_valid(): 
      ... 
    return HttpResponseRedirect('/novi_izlazni_racuni/') 

应该是这样的：

valid = new_customer.is_valid() 
    valid = new_inovce.is_valid() and valid 
    if valid: 
     a = new_customer.save() 
     ... 
     return HttpResponseRedirect('/novi_izlazni_racuni/') 

这迫使这两种形式进行验证
