在 django 中使用 Crispy_forms 时，“FormHelper”对象没有属性“append”

我是 Django 的新手，我正在尝试使用脆脆的表单来设计表单的样式。我的应用程序中有一个表单，它恰好是一个模型表单，我已经遵循了此处所说的内容https://stackoverflow.com/a/13201588/1076075 https://stackoverflow.com/a/13201588/1076075使 ModelForm 与 Cripy_forms 一起使用，但出现此错误：

'FormHelper' object has no attribute 'append'

这就是我的代码的样子forms.py:

from django import forms
from models import Ticket, Ticketuser
from crispy_forms.helper import FormHelper
from crispy_forms.layout import Submit, Layout, Fieldset, ButtonHolder
from crispy_forms.bootstrap import FormActions

class AddTicketForm(forms.ModelForm):

  def __init__(self, *args, **kwargs):
    super(AddTicketForm, self).__init__(*args, **kwargs)
    self.helper = FormHelper(self)
    self.helper.append(Submit('save', 'save'))

  class Meta:
    model = Ticket
    fields = ('id', 'comment')

  def process(self):
    data = self.cleaned_data
    data = data['comment']
    return data

如何克服这个问题并按照我想要的方式设计表单？

显然，表单助手 api 已更改，您需要使用add_input代替append now:

这是直接来自的示例the docs http://django-crispy-forms.readthedocs.org/en/latest/tags.html#fundamentals:

from crispy_forms.helper import FormHelper
from crispy_forms.layout import Submit

class ExampleForm(forms.Form):
    [...]
    def __init__(self, *args, **kwargs):
        super(ExampleForm, self).__init__(*args, **kwargs)
        self.helper = FormHelper()
        self.helper.form_id = 'id-exampleForm'
        self.helper.form_class = 'blueForms'
        self.helper.form_method = 'post'
        self.helper.form_action = 'submit_survey'

        self.helper.add_input(Submit('submit', 'Submit'))
