是否可以在Django中的表单上显示模型帮助文本作为标题属性？

I want to show the model field help_text as an HTML title attribute in a form, instead of it being appended to the end of the line, as is the default.

我想将模型字段help_text显示为表单中的HTML标题属性,而不是将其作为默认值附加到行的末尾。

I like all the information about a model Field being in one place (in the Model definition itself), and would therefore not like to specify a custom title for each widget. It is okay, however, if there is a way to specify that the title attribute of each of widgets should be equal to the value of help_text. Is that possible? I'm looking for something to the effect of:

我喜欢模型字段在一个地方(在模型定义本身中)的所有信息,因此不想为每个小部件指定自定义标题。但是,如果有一种方法可以指定每个小部件的title属性应该等于help_text的值,那也没关系。那可能吗?我正在寻找一些效果:

widgets = {'url':TextInput(attrs={'title': help_text})}

The only other way I can think of doing this, is to make custom widgets for every single one of the built-in Widget types. Is there an easier, lazier way to achieve the same effect?

我能想到的另一种方法是为内置的Widget类型中的每一个创建自定义小部件。是否有更简单,更懒惰的方式来达到同样的效果?

Using Javascript is also an option, but that would really only be a very far-off last resort. I'm thinking that this has to be a rather common use-case; how have you guys handled it in the past?

使用Javascript也是一种选择,但这实际上只是一个非常遥远的最后手段。我认为这必须是一个相当普遍的用例;你们过去怎么处理它?

2 个解决方案

#1

Model._meta.get_field('field').help_text

In your case

在你的情况下

widgets = {'url':TextInput(attrs={'title': Model._meta.get_field('url').help_text})}

#2

Here's another way using a class decorator.

这是使用类装饰器的另一种方式。

def putHelpTextInTitle (cls):
    init = cls.__init__

    def __init__ (self, *args, **kwargs):
        init(self, *args, **kwargs)
        for field in self.fields.values():
            field.widget.attrs['title'] = field.help_text

    cls.__init__ = __init__
    return cls

@putHelpTextInTitle
class MyForm (models.Form):
    #fields here

The class decorator is adapted from here

类装饰器从这里改编而来

#1

Model._meta.get_field('field').help_text
