如何在Django中向ChoiceField添加“类”？

I have a ChoiceField in my Django Form:

我的Django表格中有一个ChoiceField：

sex = forms.ChoiceField(label='', choices=SEX)

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

我想在场上添加一个类attr，这样我就可以设计它。像下面这样的东西通常有效：

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

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

但是这对ChoiceField不起作用，我得到以下错误：

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

TypeError：init（）得到一个意外的关键字参数'attrs'

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

我应该使用哪个小部件来向ChoiceField添加类？

2 个解决方案

#1

I had a quick read of https://docs.djangoproject.com/en/1.4/ref/forms/widgets/

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

which rabbited on about widgets - apparently they are

对小部件嗤之以鼻 - 显然他们是

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

Django表示HTML输入元素。窗口小部件处理HTML的呈现

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

然后每个表单字段绑定到一个小部件 - 阅读：

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

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:

对于ChoiceField，defaultWidget是“Select”（如上面的链接所示）。好的，知道正确的小部件，添加我刚才需要的类：

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

so that my final line ended up reading:

所以我的最后一行结束了：

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

Huzzah!

好哇！

#2

the ChoiceField use the forms.Select widget

ChoiceField使用forms.Select小部件

forms.Select(attrs={"name": "select_0","class": "form-control"})
