脆皮表格标签的例外情况

Question

我在尝试使用下面的脆弱表单标签时收到错误

模板评论期间出错

代码{% crispy form form.helper %}

模板html文件如下

{% load crispy_forms_tags %}
...
    {% crispy form form.helper %}
...

Forms.py包含类似这样的内容

from crispy_forms.helper import FormHelper
from crispy_forms.layout import Submit
import floppyforms as forms

class SampleForm(forms.Form):
      ...

Answer 1

不用尝试。

{% crispy form helper %}

Answer 2

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'))

然后：

{% load crispy_forms_tags %}
{% crispy example_form example_form.helper %}

这是Crispy forms documentation
