在djang中使用crispy_forms时，“FormHelper”对象没有属性“append”

Question

我是Django的新手，我正在尝试用酥脆的表单来设计表单。我的应用程序中有一个表单正好是一个modelform，我按照这里所说的https://stackoverflow.com/a/13201588/1076075使modelform与crispy_forms一起工作，但是得到了以下错误：

'FormHelper' object has no attribute 'append'

这是我的代码在forms.py中的外观：

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

如何克服这一点和风格的形式，我想要的？在

显然，表单helper api已经更改，现在需要使用add_input而不是{}：

下面是一个直接来自the docs的示例：

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'))

FormHelper从来没有append方法AFAIK。确实有一个append按钮的是布局：

self.helper.layout.append(HTML('<p>whatever<p>'))

http://django-crispy-forms.readthedocs.org/en/latest/dynamic_layouts.html#manipulating-a-layout

为此，您需要有一个布局集：

或者为您设置默认布局http://django-crispy-forms.readthedocs.org/en/latest/dynamic_layouts.html#formhelper-with-a-form-attached

我在另一个StackOverflow示例中有个错误，误导了您，对不起。在
