Django inlineformset_factoryレンダリングエラー

Question

私はinlinefactoryを使用して2つのモデルでビューを構築しようとしています。これは、レンダリングさModels.py

class serviceinvoice(models.Model): 
    user=models.ForeignKey(User,related_name='invoice')  
    invoice_number=models.PositiveIntegerField() 
    #invoice_no = models.CharField(max_length = 500, default = increment_invoice_number, null = True, blank = True) 
    invoice_date = models.DateField() 
    invoice_receivable=models.ForeignKey(Receivables,null=True) 
    total_amount=models.DecimalField(decimal_places=2,max_digits=20) 
    total_amountwithtax=models.DecimalField(decimal_places=2,max_digits=20) 

    def __str__(self): 
     return self.invoice_number 

class serviceinvoiceitems(models.Model): 
    user=models.ForeignKey(settings.AUTH_USER_MODEL,related_name='serviceinvoiceitems') 
    invoice_number=models.ForeignKey(serviceinvoice) 
    Product=models.CharField(max_length=1000,null=True) 
    UOM=models.CharField(max_length=100,null=True) 
    Quantity=models.FloatField(null=True) 
    Rate=models.FloatField(null=True) 
    Tax_rate=models.FloatField(null=True) 

    def __str__(self): 
     return self.invoice_number 

forms.py

createinvoiceformset = inlineformset_factory(serviceinvoice, serviceinvoiceitems,fields='__all__') 

class createinvoice(forms.ModelForm): 
    class Meta: 
     model = serviceinvoice 
     exclude = ('user',) 
     widgets = { 
      'invoice_date': forms.DateInput(attrs={'class':'datepicker'}), 
     } 

views.py

@login_required 
def createinvoice(request): 
    if request.method == 'POST': 
     inv_form=createinvoice(data=request.POST)   
     if inv_form.is_valid(): 
      new_form=inv_form.save(commit=False) 
      new_formset=createinvoiceformset(request.POST,instance=new_form) 
      if new_formset.is_valid(): 
       new_form.save() 
       new_formset.save() 
       return HttpResponse('Invoice created') 
    else: 
     inv_form=createinvoice() 
     new_formset=createinvoiceformset(instance=serviceinvoice()) 
     inv_form.fields["invoice_receivable"].queryset=Receivables.objects.filter(user=request.user) 
    return render(request,'account/createinvoice.html',{'inv_form':inv_form,'new_formset':new_formset}) 

次のエラーがテンプレートにあります。

_wrapped_view（1つの）必要な位置引数不足している： '要求'

Answer 1

あなたのビュー名フォームcreateinvoiceとcreateinvoice衝突を。彼らは違うはずです。

あなたのコードは、関数名（例えばdef create_invoice(...)）、およびクラス名（例えばclass CreateInvoice(...)、CreateInvoiceFormSet、...）
