django localflavor USStateSelect（）inital值 [英] django localflavor USStateSelect() inital value

问题描述

我试图在窗体中使用django localflavor小部件USStateSelect（），但是我希望小部件默认选择内布拉斯加。小部件只接受一个attrs arg，所以我试图理解我必须设置什么属性以获得所需的结果。以下是我在forms.py中的内容：

I'm trying to use the django localflavor widget USStateSelect() in a form, but I want the widget to have Nebraska selected by default. The Widget only accepts an attrs arg, so I'm trying to understand what attributes I have to set to get the desired result. Here's what I've got in my forms.py:

state = forms.CharField(widget=USStateSelect(attrs={'value':'NE'}))

这是HTML select元素的文档： http://www.w3.org/html /wg/drafts/html/CR/forms.html#the-select-element

This is the docs for the HTML select element: http://www.w3.org/html/wg/drafts/html/CR/forms.html#the-select-element

这是localflavor的文档： https://django-localflavor.readthedocs.org/en/latest/_modules/localflavor/我们/表单/

This is the docs for localflavor: https://django-localflavor.readthedocs.org/en/latest/_modules/localflavor/us/forms/

<option value="NE" selected>Nebraska</option>

这是我需要在我的HTML中，但我无法弄清楚attrs dict需要包含才能实现这个结果。我已经尝试添加'selected'：'selected'和'class'：'selected'到dict，但是没有这样做。

This is what I need to have in my html, but I can't figure out what the attrs dict needs to contain to achieve this result. I've tried adding 'selected':'selected' and 'class':'selected' to the dict, but that's not doing it.

我看到一些人问如何添加一个空选项，但没有人似乎希望将其默认为特定状态。任何想法都是受欢迎的。

I've seen a number of people asking how to add an empty option, but no one seems to want to make it default to a specific state. Any ideas are welcome.

谢谢，

Anthony

推荐答案

您可以设置如下初始值：

You can set the initial value like so:

state = forms.CharField(widget=USStateSelect(), initial='NE')

或者您可以在实例化形式：

or you can set it when you instantiate the form:

form = ExampleForm(initial={'state': 'NE'})
