制作提交按钮表单字段 [英] Making a submit button form field

问题描述

因此存在一个代码段此处：

我打算重用它，但是当我在forms.py中声明它并渲染html时。

I was going tor reuse this, but when I declare this in my forms.py, and I render the html..

submit_button = SubmitButtonField()

value 未提供（转义为字符串 None ），而 name 默认为 submit_button ，可能是由于 forms.Widget 构造函数所致。

value is not supplied (it's escaped to string None), while name is default to submit_button, probably because of the forms.Widget constructor.

如何提供名称和价值？我试图为小部件编写一个初始化方法...

How can I supply the name and the value? I tried to write an init method for the widget...

def __init__(self, name, value, label, attrs):        
    print '%s, %s, %s, %s' %(name, value, label, attrs)
    self.name, self.value,self.label = name, value, label
    self.attrs = attrs

但是如果该字段是总是（默认）默认使用小部件 SubmitButtonWidget ...代替，我应该在字段init方法中提供这些值。但这不允许我这样做。

But this doesn't quite make sense if the field is always (supposedly) default to use the widget SubmitButtonWidget... instead I should supply these values in the field init method. But it doesn't allow me to do.

我应该如何重写此代码段，使其可以接受我提供的值？

How should I rewrite this snippet so it can accept my supplied values?

推荐答案

如摘要顶部的注释中所述，用法是

As written in the comment at the very top of the snippet, the usage is

submit_button = SubmitButtonField(label="", initial=u"Your submit button text")

您缺少的值来自初始关键字参数。名称是表单字段的名称。

Your missing value comes from the initial keyword argument. The name is the name of the form field.
