Django CreateView类如何实例化模型？

from django.db import models

class MyModel(models.Model):
    name = models.CharField(max_length=100)
    description = models.TextField()

from django import forms
from .models import MyModel

class MyModelForm(forms.ModelForm):
    class Meta:
        model = MyModel
        fields = ['name', 'description']

from django.urls import path
from .views import MyModelCreateView

urlpatterns = [
    path('mymodel/create/', MyModelCreateView.as_view(), name='mymodel_create'),
]

from django.urls import reverse_lazy
from django.views.generic.edit import CreateView
from .models import MyModel
from .forms import MyModelForm

class MyModelCreateView(CreateView):
    model = MyModel
    form_class = MyModelForm
    template_name = 'mymodel_form.html'  # 指定模板文件
    success_url = reverse_lazy('mymodel_list')  # 成功创建后的重定向URL

<!-- mymodel_form.html -->
<form method="post">
    {% csrf_token %}
    {{ form.as_p }}
    <button type="submit">Submit</button>
</form>

<!-- mymodel_form.html -->
<form method="post">
    {% csrf_token %}
    {{ form.as_p }}
    {% if form.errors %}
        <div class="error">
            {{ form.errors }}
        </div>
    {% endif %}
    <button type="submit">Submit</button>
</form>

class MyModelCreateView(CreateView):
    # ...
    success_url = reverse_lazy('mymodel_list')  # 确保'mymodel_list'是一个有效的URL名称
