Disable autocomplete on textfield in Django?
提问by tau-neutrino
Does anyone know how you can turn off autocompletion on a textfield in Django?
有谁知道如何关闭 Django 中文本字段的自动完成功能？
For example, a form that I generate from my model has an input field for a credit card number. It is bad practice to leave autocompletion on. When making the form by hand, I'd add a autocomplete="off" statement, but how do you do it in Django and still retain the form validation?
例如，我从模型生成的表单有一个信用卡号输入字段。保持自动完成是不好的做法。手工制作表单时，我会添加一个 autocomplete="off" 语句，但是您如何在 Django 中执行此操作并仍然保留表单验证？

In your form, specify the widget you want to use for the field, and add an attrsdictionary on that widget. For example (straight from the django documentation):
在您的表单中，指定要用于该字段的小部件，并attrs在该小部件上添加字典。例如（直接来自django 文档）：
class CommentForm(forms.Form):
name = forms.CharField(
widget=forms.TextInput(attrs={'class':'special'}))
url = forms.URLField()
comment = forms.CharField(
widget=forms.TextInput(attrs={'size':'40'}))
Just add 'autocomplete'='off'to the attrs dict.
只需添加'autocomplete'='off'到 attrs 字典。

Add the autocomplete="off" to the form tag, so you don't have to change the django.form instance.
将 autocomplete="off" 添加到表单标记中，这样您就不必更改 django.form 实例。
<form action="." method="post" autocomplete="off">
{{ form }}
</form>
<form action="." method="post" autocomplete="off">
{{ form }}
</form>

If you are defining your own forms, you can add attributes to your fields in the form.
如果您要定义自己的表单，则可以向表单中的字段添加属性。
class CommentForm(forms.Form):
name = forms.CharField(widget=forms.TextInput(attrs={
'autocomplete':'off'
}))
If you are using modelforms, you won't have the luxury of defining field attributes in the form. However, you can use __init__to add required attributes.
如果您使用模型表单，您将无法在表单中定义字段属性。但是，您可以使用__init__添加必需的属性。
class CommentForm(forms.ModelForm):
def __init__(self, *args, **kwargs):
super(CommentForm, self).__init__(*args, **kwargs)
self.fields['name'].widget.attrs.update({
'autocomplete': 'off'
})
You can also add attributes from Meta
您还可以从 Meta
class CommentForm(forms.ModelForm):
class Meta:
widgets = {
'name': TextInput(attrs={'autocomplete': 'off'}),
}

For me adding extra attribute in templates also worked:
对我来说，在模板中添加额外的属性也有效：
`<form method="POST", autocomplete="off">
{% csrf_token %}
{{ form.as_p }}`
