设置在线预订表单，获取此错误- TypeError at /bookings/ 'OnlineForm‘对象不可调用

Question

有人能帮忙吗。我目前正在通过一个项目，在那里我试图创建一个虚拟餐厅的网站，包括在线订票表。我收到以下错误消息: TypeError at /bookings/ 'OnlineForm‘对象不可调用

我看过很多视频，读过Django文档，我仍然不知道自己做错了什么。我对Django很陌生，所以这一切都是我的学习。你能给出的任何建议都会受到极大的感谢。提前谢谢你

这是我的密码：

view.py：

class BookingForm(FormView):
    form_class = OnlineForm()
    args = {}
    def booking_view(self, request):
        if request.method == 'POST':
            form = OnlineForm(request.POST)
        
        return render(request, 'bookings.html')

models.py

OCCASION_CHOICE = (
    ('Birthday', 'BIRTHDAY'),
    ('Anniversary', 'ANNIVERSARY'),
    ('Graduation', 'GRADUATION'),
    ('Communion', 'COMMUNION'),
    ('Confirmation', 'CONFIRMATION'),
    ('Christening', 'CHRISTENING'),
    ('Date Night', 'DATE NIGHT'),
)

class Booking(models.Model):
    name = models.CharField(max_length=50)
    email_address = models.EmailField()
    phone = models.IntegerField()
    number_of_people = models.IntegerField(validators=[MinValueValidator(1), MaxValueValidator(10)],default='1', help_text='For parties of more than 10, please call us on 021 4569 782')
    date = models.DateField()
    time = models.TimeField()
    occasion = models.CharField(max_length=100, choices=OCCASION_CHOICE, default='Birthday')

    def __str__(self):
        return self.name

forms.py：

from django.forms import ModelForm
from .models import Booking


class OnlineForm(ModelForm):
    class Meta:
        model = Booking
        fields = '__all__'

urls.py：

from . import views
from .views import BookingForm
from django.urls import path

app_name = 'bookingsystem'


urlpatterns = [
    path('', views.Home.as_view(), name='home'),
    path('bookings/', BookingForm.as_view(), name='bookings'),
    path('menus/', views.Menus.as_view(), name='menus'),
    path('edit_bookings', views.editBooking.as_view(), name='edit_bookings'),
]

bookings.html：

{% extends "base.html" %}

{% block content %}

<form method="POST">
    {% csrf_token %}
    {{form}}
    
   <button id="submit-button" class="btn btn-success">Book Now</button>
</form>

{%endblock%}

根据django描述的说法，对于FormView，您没有定义自己的POST方法的选项。将您的观点重写为

class BookingForm(FormView):
    template_name = 'bookings.html'
    form_class = OnlineForm

会解决这个问题。尽管您需要添加一个form_valid方法来定义在提交有效数据的表单时要执行的操作。
