TypeError：__ init __（）得到了一个意外的关键字参数＆＃39; widget＆＃39;

Question

运行命令python manage.py runserver时出现运行时服务器错误。终端显示错误： 第35行，在CustomertaskForm中，startdate = forms.DateInput（widget = forms.DateField（））TypeError： init （）得到了一个意外的关键字参数＆＃39; widget＆＃39;

forms.py

class CustomertaskForm(forms.ModelForm):

    def __init__(self, *args, **kwargs):
        super(CustomertaskForm, self).__init__(*args, **kwargs)

    title=forms.CharField(widget=forms.TextInput(attrs={'class':'form-control', 'required': 'required'}))
    discription=forms.CharField(widget=forms.TextInput(attrs={'class': 'form-control', 'required': 'required'}))
    startdate=forms.DateInput(widget=forms.DateField())
    enddate=forms.DateInput(widget=forms.DateField())

    class Meta:
        model=Customertask
        fields=['title','discription','startdate','enddate']

models.py

class Customertask(models.Model):
   title=models.CharField(max_length=200)
   discription=models.CharField(max_length=500)
   startdate=models.DateTimeField()
   enddate=models.DateTimeField()

view.py

def createtasks(request):
if request.method == 'POST':
    form=CustomertaskForm(request.POST)
    if form.is_valid():
        tasksave=Customertask.objects.create(
            customer=models.ForeignKey(Customer)
            title=form.cleaned_data['title'],
            discription = form.cleaned_data['discription'],
            startdate=form.cleaned_data['startdate'],
            enddate=form.cleaned_data['enddate']
        )
        tasksave.save()
        return HttpResponseRedirect('/customer/tasktable')
else:
    form=CustomertaskForm()
return render(request, 'customer/createtasks.html', {'form': form})

迁移很重要，每次在models.py或forms.py中进行更改时，请明确注释迁移。

Answer 1

您的小部件和字段方式错误 - DateField是一个字段，DateInput是一个小部件。因此，您的表单使用forms.DateField(widget=forms.DateInput())。但是，由于DateField默认使用DateInput，因此您可以完全删除小部件参数：

class CustomertaskForm(forms.ModelForm):
    ...
    startdate=forms.DateField()
    enddate=forms.DateField()

另外，您可以通过保存模型表单来创建任务。您无需手动拨打Customertask.objects.create()：

if form.is_valid():
    tasksave=form.save()
    return HttpResponseRedirect('/customer/tasktable')

Answer 2

  

在表单中尝试此操作。

     

Forms.py

        widgets = {
        'Title': forms.TextInput(attrs={'class': 'form-control','required':'required'}),
        'Description': forms.TextInput(attrs={'class': 'form-control','required':'required'}),
        'StartDate': forms.DateInput(attrs={'class': 'form-control', 'type': 'date','required':'required'}),
        'EndDate': forms.DateInput(attrs={'class': 'form-control', 'type': 'date','required':'required'}),
       }
