ModelFormフィールドattrs

Question

django docsによれば、モデルフォームフィールドはattrsを受け入れます。私はattrsを適用しようとすると、私は私が作るしようとしてるのフォームは非常に単純です

TypeError: init() got an unexpected keyword argument 'attrs'

を取得し、私はちょうどそれにスタイルを適用したいです。私は間違って何をしていますか？

forms.py

from django import forms 

from .models import ServiceReportModel 


class ServiceReportCreateForm(forms.ModelForm): 
    class Meta: 
     model = ServiceReportModel 
     fields = [ 
      'request_number', 
      'request_reason', 
      'actions_taken', 
     ] 


class ServiceReportUpdateForm(forms.ModelForm): 
    class Meta: 
     model = ServiceReportModel 
     fields = [ 
      'report_number', 
      'request_number', 
      'request_reason', 
      'actions_taken', 
     ] 
     widgets = { 
      'report_number': forms.CharField(attrs={'class': 'form-control'}), 
      'request_number': forms.CharField(attrs={'class': 'form-control'}), 
      'request_reason': forms.CharField(attrs={'class': 'form-control'}), 
      'actions_taken': forms.Textarea(attrs={'class': 'form-control'}), 
     } 

views.py

from django.views.generic.edit import CreateView, UpdateView, DeleteView 
from django.urls import reverse_lazy 

from .forms import ServiceReportCreateForm, ServiceReportUpdateForm 
from .models import ServiceReportModel 


class ReportCreateView(CreateView): 
    form_class = ServiceReportCreateForm 
    model = ServiceReportModel 


class ReportCreateView(UpdateView): 
    form_class = ServiceReportUpdateForm 
    model = ServiceReportModel 


class ReportDeleteView(DeleteView): 
    model = ServiceReportModel 
    success_url = reverse_lazy('reports-list') 

models.py

import uuid 
from django.urls import reverse 
from django.db import models 
from django.forms import ModelForm 
from main import models as main_models 
from customers import models as customers_models 


class ServiceReportModel(models.Model): 
    report_number = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False) 
    request_number = models.ForeignKey(ServiceRequestModel, 
             on_delete=models.PROTECT, 
             null=True, 
             related_name='s_report_number' 
            ) 
    reported_by = models.ForeignKey(main_models.MyUser, editable=False, related_name='reports') 
    reported_date = models.DateTimeField(auto_now_add=True) 
    updated_by = models.ForeignKey(main_models.MyUser, editable=True, blank=True, null=True, related_name='+') 
    updated_date = models.DateTimeField(auto_now=True) 
    request_reason = models.CharField(max_length=255, null=True) 
    actions_taken = models.TextField() 

    def get_absolute_url(self): 
     return reverse('service-report', kwargs={'pk': self.pk})

フィールドattrsを受け入れない、ウィジェットが行います。同様に、widgetsディクショナリではフィールドではないウィジェットが必要です。 TextInputを使用してください。
