如何在Django中将CreateView与crispy-forms一起使用

我想将CreateView与脆皮表格生成的布局一起使用.但是，似乎我在 forms.py 中传递给 self.helper 的所有内容都被忽略了.表单可以很好地呈现，但是仅包含CreateView生成的字段-传递给 Layout 的所有字段都将丢失.

I want to use CreateView along with crispy-forms generated layout. However, it seems that everything I pass to self.helper in forms.py is ignored. Form renders nicely, but only with fields generated by CreateView - all fields passed to Layout are missing.

我的views.py

My views.py

class MyView(CreateView):
    form_class = MyForm
    model = MyModel

    def form_valid(self, form):
        pass

我的forms.py:

My forms.py:

from django.forms import ModelForm, Textarea
from crispy_forms.helper import FormHelper
from crispy_forms.layout import Submit, Layout
from crispy_forms.bootstrap import FormActions

from .models import MyModel

class MyForm(ModelForm): 

    def __init__(self, *args, **kwargs):
        super(MyForm, self).__init__(*args, **kwargs)
        self.helper = FormHelper(self)
        self.helper.form_method = 'POST'
        self.helper.add_input(Submit('submit', 'Submit'))
        self.helper.layout = Layout( 
            FormActions(Submit('BlahBlah', 'BlahBlah', css_class='btn-primary')))

    class Meta:
        model = MyModel
        fields = ['xxx', 'yyy']

我的image_form.html:

My image_form.html:

{% load crispy_forms_tags %}
...
<form action="" method="post" enctype="multipart/form-data">
    {% csrf_token %}
    {{ form|crispy }}
</form>

我还应该做些什么才能使其正常工作?

What else should I do to make it work?
