将属性添加到脆皮形式的Django [英] Adding Attribute to crispy forms django

问题描述

大家好，我正在使用引导程序开关，看来我想添加标签需要：

Hey guys I am using bootstrap switch and it looks like if I want to add a label I need to:

<input name="switch-labelText" type="checkbox" data-label-text="Label">

我使用的是脆皮表格，可以看到我可以使用Field来添加属性，如下所示：

I am using crispy forms and I can see that I can do add attribute using the Field like so:

Field('field_name', css_class="black-fields")

这对我来说都有意义，但我似乎无法添加data-label-text。所以我的问题是我可以使用酥脆的表格制作自定义属性吗？

This all makes sense to me but I can't seem to add data-label-text. So my question is can I make a custom attribute with crispy forms?

这是我的表格：

class InstanceCreationForm(forms.Form):
    some_field = forms.BooleanField(required=False)
    some_field2 = forms.BooleanField(required=False)
    some_field3 = forms.BooleanField(required=False)

    def __init__(self, *args, **kwargs):
        super(InstanceCreationForm, self).__init__(*args, **kwargs)
        self.helper = FormHelper()
        self.helper.form_show_labels = False
        self.helper.layout = Layout(
            #This is a syntax error
            Field('some_field', data-label-text="whatever")
        )
        self.helper.add_input(Submit('submit', 'Submit'))

推荐答案

来自文档：

如果要设置html属性，并用连字符（如 data-name ）隔开，因为Python在关键字参数中不支持连字符和连字符是HTML中的常用符号，下划线将转换为连字符，因此您可以这样做：
Field（'field_name'，data_name = whatever）

If you want to set html attributes, with words separated by hyphens like data-name, as Python doesn’t support hyphens in keyword arguments and hyphens are the usual notation in HTML, underscores will be translated into hyphens, so you would do: Field('field_name', data_name="whatever")

因此，您需要使用关键字 data_label_text 。

So you need to use the keyword data_label_text instead.

Field('some_field', data_label_text="whatever")
