将属性添加到< input>标签为django ModelForm字段 [英] Adding an attribute to the <input> tag for a django ModelForm field

问题描述

我有一个django模型，我使用ModelForm作为表单显示。默认值在很大程度上对我来说非常有用。

但是，我希望我的html < input ...> 标签有一个额外的属性，即我想包括一个占位符属性，如下所示：

 < input placeholder ={{field.label}}... /> 
  

将这个属性添加到我的html中最简单的方法是什么？据我所知，我需要实现自己的过滤器来输出该字段，但是当我想做的所有事情都是一个人离开，但添加一个附加属性时，这似乎是过分的。

解决方案

请参阅文档

 类AuthorForm（ModelForm）：
 class Meta：
 model = Author 
 widgets = {
'name'：TextInput（attrs = {'placeholder'：'name'}），
} 
  

您可以随时创建自己的从TextInput派生的小部件，并包含占位符属性，并使用小部件字典只需将字段映射到新的小部件，而不必为每个字段指定占位符属性。

I have a django model that I'm displaying as a form using a ModelForm. The defaults work very well for me for the most part.

However, I would like my html <input ...> tags to have one additional attribute, namely I would like to include a placeholder attribute, like the following:

<input placeholder="{{field.label}}" ... />

What is the easiest way to add this attribute to my html? As far as I can tell it appears I need to implement my own filter to output the field, but this seems like overkill when all i want to do is leave everything alone but add one additional attribute.

解决方案

See the documentation

class AuthorForm(ModelForm):
    class Meta:
        model = Author
        widgets = {
            'name': TextInput(attrs={'placeholder': 'name'}),
        }

You could always create your own widget that derives from TextInput and includes the placeholder attribute, and use the widgets dictionary to simply map fields to your new widget without specifying the placeholder attribute for every field.
