将django表单字段更改为隐藏字段 [英] Change a django form field to a hidden field

问题描述

我有一个django表单，一个 RegexField （与普通文本输入字段非常相似）。在我看来，在某些条件下，我想把这个隐藏起来，并试图保持表单尽可能的相似。

I have a django form with a RegexField (which is very similar to a normal text input field). In my view, under certain conditions I want to hide this from the user, and trying to keep the form as similar as possible.

打开这个字段的最好方法是什么成为 HiddenInput 字段？我知道我可以使用 form ['fieldname']设置字段的属性field.widget.attr ['readonly'] ='readonly'，我可以设置所需的初始值与 form.initial ['fieldname'] ='mydesiredvalue'。但是，这不会改变窗口小部件的形式。

What's the best way to turn this field into a HiddenInput field? I know I can set attributes on the field with form['fieldname'].field.widget.attr['readonly'] = 'readonly', and I can set the desired initial value with form.initial['fieldname'] = 'mydesiredvalue'. However that won't change the form of the widget.

什么是最佳/最django-y /最简单的hacky方式使这个字段为$ code> < input type =hidden field？

What's the best/most django-y/least hacky way to make this field a <input type="hidden" field?

推荐答案

如果您有自定义模板和视图您可以排除该字段并使用 {{modelform.instance.field}} 获取该值。

If you have a custom template and view you may exclude the field and use {{ modelform.instance.field }} to get the value.

还您可能更喜欢在视图中使用：

also you may prefer to use in the view:

form.fields['field_name'].widget = forms.HiddenInput()

但我不确定它会保护发布的保存方式。

but I'm not sure it will protect save method on post.
