在 Django forms.ChoiceField 上设置选定的值 [英] Setting the selected value on a Django forms.ChoiceField

问题描述

这是表单中的字段声明:

Here is the field declaration in a form:

max_number = forms.ChoiceField(widget = forms.Select(), 
    choices = ([('1','1'), ('2','2'),('3','3'), ]), initial='3', required = True,)

我想将初始值设置为 3 但这似乎不起作用.我玩过参数、引号/无引号等......但没有变化.

I would like to set the initial value to be 3 and this doesn't seem to work. I have played about with the param, quotes/no quotes, etc... but no change.

如果可能的话，有人能给我一个明确的答案吗?和/或对我的代码片段进行必要的调整?

Could anyone give me a definitive answer if it is possible? And/or the necessary tweak in my code snippet?

我使用的是 Django 1.0

推荐答案

在实例化表单时尝试设置初始值:

Try setting the initial value when you instantiate the form:

form = MyForm(initial={'max_number': '3'})
