Django Crispy 形式 - 位置参数跟随关键字参数错误

Question

我是 crispy 表单的新手，我正在尝试使用 bootstrap 将一些表单字段设置为 bootstrap 面板，然后我会将一些其他字段添加到另一个面板中，依此类推。构建第一个面板时出现以下错误。

有些地方出了问题，但我不确定是什么？

Traceback:

这是我的forms.py

class EditSiteForm(forms.ModelForm):

    class Meta:
        model = SiteData
        fields = ['location', 'site_type', 'bgp_as', 'opening_date','last_hw_refresh_date','is_live',
                    'tel','address','town','postcode',
                    'regional_manager','regional_manager_tel','assistant_manager','assistant_manager_tel' ,'duty_manager','duty_manager_tel']

    def __init__(self, *args, **kwargs):
        super(EditSiteForm, self).__init__(*args, **kwargs)
        self.helper = FormHelper(self)
        self.helper.form_id = 'edit_site_form'
        self.helper.form_method = 'POST'
        self.helper.add_input(Submit('submit', 'Save', css_class='btn-primary'))
        self.helper.layout = Layout(
           Div(title='', css_class='panel panel-primary',
                Div(title='Details', css_class='panel-heading'),
                Div(css_class='panel-body',
                    Field('location', placeholder='Location'),
                    Div('site_type', title="Site Type")
                ),
            )
        )

这是它抱怨的台词

Div(title='Details', css_class='panel-heading'),

Answer 1

我觉得是真的在抱怨这个：

Div(css_class='panel-body',
    Field('location', placeholder='Location'),
    Div('site_type', title="Site Type")
),

您在关键字参数 (css_class) 之后传递了两个位置参数 (Field 和 Div)。

您可以通过重新安排来解决此问题：

Div(
    Field('location', placeholder='Location'),
    Div('site_type', title="Site Type")
    css_class='panel-body',
),
