如何添加“班级”到Django中的ChoiceField？ [英] How do I add a "class" to a ChoiceField in Django?

问题描述

我的Django表单中有一个 ChoiceField ：

I have a ChoiceField in my Django Form:

gender = forms.ChoiceField(label='', choices=GENDER)

我想添加一个 class attr 到字段，这样我就可以设置样式。像下面这样的东西通常可以工作：

I'd like to add a class attr to the field so I can style it. Something like the following usually works:

forms.Field(label="Display name",help_text='',widget=forms.TextInput(attrs={'class': 'wideInput'}))

但这不是为ChoiceField工作，我得到以下错误：

But this doesn't work for the ChoiceField, I get the following error:

TypeError： init （）有一个意外的关键字参数'attrs'

TypeError: init() got an unexpected keyword argument 'attrs'

我应该使用什么 widget 来添加类

What widget should I use in order to add a class to my ChoiceField?

推荐答案

我快速阅读了 https://docs.djangoproject.com/en/1.4/ref/forms/widgets/

涉及到小部件-显然，它们是

which rabbited on about widgets - apparently they are

Django对HTML输入元素的表示。小部件处理HTML的呈现

Django’s representation of a HTML input element. The widget handles the rendering of the HTML

然后将每个表单字段绑定到小部件-阅读以下内容：

and then each form field is tied to a widget - have a read of:

https://docs.djangoproject.com/zh-CN/1.4/ref/forms/fields/#built-in-fields

对于ChoiceField， defaultWidget是选择（如上面的链接所述）。确定，知道正确的小部件，添加我刚需要的类：

for the ChoiceField, the defaultWidget is "Select" (as noted in the above link). Ok, knowing the right widget, to add the class i just needed:

widget=forms.Select(attrs={'class':'regDropDown'})

，以便最后一行显示为：

so that my final line ended up reading:

gender = ChoiceField(label='', choices=SEX, widget=forms.Select(attrs={'class':'regDropDown'}))

Huzzah！
