Question

当我运行以下程序时，出现错误：AttributeError：'CreateBatchForm'对象没有属性'get'

我试图更改对象的名称并更新了传递给“ create_batch_admin”形式的参数，但这无济于事。

urls.py

urlpatterns += [   
    #path('batches/create/', views.CreateBatchForm, name='create_batch_admin'),
    path('batches/create/', views.CreateBatchForm, name='create_batch_admin'),
]

        errors = None
        # Check if the form is valid:
        if form.is_valid():
            Batch.objects.create(

            # redirect to a new URL:

朋友，我刚刚发现我需要更改文件 urls.py 从这个

   path('batches/create/', views.CreateBatchForm, name='create_batch_admin'),

对此

   path('batches/create/', views.create_batch_admin, name='create_batch_admin'),

AttributeError：'CreateBatchForm'对象没有属性'get'
