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

我有一个带有 RegexField 的 Django 表单，它与普通的文本输入字段非常相似.

I have a Django form with a RegexField, which is very similar to a normal text input field.

在我看来，在某些情况下，我想对用户隐藏它，并尽量保持表单的相似性.将此字段转换为 HiddenInput 字段的最佳方法是什么?

In my view, under certain conditions I want to hide it from the user, and trying to keep the form as similar as possible. What's the best way to turn this field into a HiddenInput field?

我知道我可以在字段上设置属性:

I know I can set attributes on the field with:

form['fieldname'].field.widget.attr['readonly'] = 'readonly'

我可以设置所需的初始值:

And I can set the desired initial value with:

form.initial['fieldname'] = 'mydesiredvalue'

但是，这不会改变小部件的形式.

However, that won't change the form of the widget.

使该字段成为 <input type="hidden"> 字段的最佳/最django-y"/最不hacky"的方法是什么?

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 }} 获得价值.

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

您也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帖子的保存方法.

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