Django：フォームにファイルを追加すると複数の引数エラーが発生する

Question

こんにちは私はDjangoプロジェクトを完璧に動作させています。今は、ドキュメントをアップロードするためにフィールドを追加する必要があります。 しかし、ファイルstuffsを追加した後、Djangoはエラーを出します。 1日を通してグーグルでもそれを解決することはできません。

Models.py

class salesman(models.Model): 
    user=models.ForeignKey(settings.AUTH_USER_MODEL) 
    company=models.ForeignKey(Organisation,related_name='salesmancomp') 
    salesman_name=models.CharField(max_length=250) 
    salesman_address=models.CharField(max_length=750,null=True,blank=True) 
    salesman_PAN=models.CharField(max_length=250,null=True,blank=True) 
    salesman_commission_rate=models.FloatField(null=True,blank=True) 
    attachment = models.FileField(null=True,blank=True) 

    class Meta: 
     unique_together=(('company','salesman_name'),) 

    def __str__(self): 
     return self.salesman_name 

forms.py

class salesmanform(forms.ModelForm): 
    def __init__(self,user, *args, **kwargs): 
     self.request = kwargs.pop('request', None) 
     super(salesmanform, self).__init__(*args, **kwargs) 

    class Meta: 
     model=salesman 
     fields=('salesman_name','salesman_PAN','salesman_commission_rate','salesman_address','attachment',) 
     widgets = { 
      'salesman_address': forms.Textarea 
     } 
    def clean(self): 
     cleaned_data=self.cleaned_data 
     salesman_name=cleaned_data['salesman_name'] 
     pk=self.instance.pk 
     insert = pk ==None 
     if insert: 
      try: 
       salesman.objects.get(salesman_name=salesman_name,company=self.request.user.company.entity) 
      except salesman.DoesNotExist: 
       pass 
      else: 
       raise forms.ValidationError("Salesman already exist.") 
     else: 
      pass  
     return cleaned_data 

Views.py

@login_required 
def salesmancreate(request): 

     action="Salesman Creation" 
     if request.method == 'POST': 
      rec_form=salesmanform(request.FILES,request=request,user=request.user,data=request.POST) 
      if rec_form.is_valid(): 
       new_rec = rec_form.save(commit=False) 
       new_rec.user = request.user 
       new_rec.company=request.user.company.entity 
       new_rec.save() 
       return HttpResponseRedirect(reverse('salesmancreate'),{'section':'added'},messages.add_message(request, messages.SUCCESS,'Salesman added Succesfully')) 
     else: 
      rec_form=salesmanform(request=request,user=request.user) 
     receivablescreated=salesman.objects.filter(company=request.user.company.entity).order_by('-id') 
     return render(request,'account/salesman.html',{'rec_form':rec_form,'receivablescreated':receivablescreated,'action':action}) 

マイテンプレート

<form action="." method="post"> 

    <div class="form-group"> 

     {{ rec_form.salesman_name|attr:"class:form-control"|attr:"placeholder:Salesman Name"}} 
    </div> 

     <div class="input-group margin-b-20"> 

     {{ rec_form.salesman_commission_rate|attr:"class:form-control"|attr:"placeholder:Commission Perentage" }} 
     <span class="input-group-addon"><i class="fa fa-envelope-o fa-percent"></i></span> 
    </div> 
     <div class="form-group"> 

     {{ rec_form.salesman_PAN|attr:"class:form-control"|attr:"placeholder:PAN of Salesman" }} 
    </div> 
    <div class="form-group"> 

     {{ rec_form.salesman_address|attr:"class:form-control"|attr:"style:height: 83px;"|attr:"placeholder:Address of Salesman" }} 
    </div> 
    <div class="form-group"> 

     {{ rec_form.attachment|attr:"class:form-control"|attr:"style:height: 83px;"|attr:"placeholder:Address of Salesman" }} 
    </div> 


    <div class="form-group clearfix">            
     <div class="pull-right"> 
     {% csrf_token %} 
      <button type="submit" class="btn btn-success rounded">Save</button> 
     </div> 
    </div> 
</form>

Answer 1

最初の引数がuserですが、あなたの代わりにrequest.FILESを渡すようにするには、__init__メソッドをオーバーライドします。あなたはクラスのコンストラクタのシグネチャを変更する場合は特に、経験則として

rec_form = salesmanform(user=request.user, data=request.POST, 
         files=request.FILES, request=request) 

に

rec_form=salesmanform(request.FILES,request=request,user=request.user,data=request.POST) 

、名前が付けられ、位置引数を混在しないようにしよう：行を変更します。また、PEP-8クラス命名規則に準拠するために、フォーム名をSalesmanFormに変更することを検討してください。
