はforms.ModelFormにウィジェットを割り当てるときに、私は次のエラーを取得しています

Question

ウィジェット。 このエラーを修正する方法を提案してください。

from django import forms 
from django.forms import ModelForm, CharField 
from .models import * 

class CreateTaskMaster(forms.ModelForm): 
    class Meta(): 
     model = TaskMaster 
     fields = ["sid", "tasktype", "task_title", "task_description", 
      "datacenter", "priority", "sourceincident", "processingteam", 
       "duedate"] 
    widgets = { 
     'duedate': CharField(widget=forms.TextInput(attrs={'class': 'form- 
       control mr-sm-2'})), 
       } 

forms.py Model.pyが

Class TaskMaster(models.Model): 
    sid = models.CharField(max_length=3) 
    processor = models.ForeignKey(User,null=True) 
    tasktype = models.ForeignKey(TaskTypeTable, null=True) 
    task_title = models.TextField(null=True) 
    task_description = models.TextField(null=True) 
    datacenter = models.ForeignKey(DatacenterTable,null=True) 
    priority = models.ForeignKey(PriorityTable, null=True) 
    status = models.ForeignKey(StatusTable,default=1, null=True) 
    pid = models.IntegerField(null=True) 
    sourceincident = models.URLField(null=True) 
    errorincident = models.URLField(null=True) 
    processingteam = models.ForeignKey(TeamTable, null=True) 
    createddate = models.DateField(("Date"), default=datetime.date.today) 
    duedate = models.DateField(("Date"), default=datetime.date.today) 
    istaskactive = models.BooleanField(default=True) 

    class Meta: 
    ordering = ('duedate',)

、次の方法を試してみてくださいのみフォームクラスを置き換える：

class CreateTaskMaster(forms.ModelForm): 
    class Meta(): 
     model = TaskMaster 
     fields = ["sid", "tasktype", "task_title", "task_description", 
      "datacenter", "priority", "sourceincident", "processingteam", 
       "duedate"] 
     widgets = {'duedate': forms.TextInput(attrs={'class': 'form- 
       control mr-sm-2'}), 
       }
