from flask.ext.wtf.html5 import NumberInput

class Form(Form):
    value = NumberInput( [Required()])
    submit = SubmitField('Next')

{{ form.value }}

上面的代码将输出以下内容:

The code above will output this:

<wtforms.widgets.html5.NumberInput object at 0x3c94a50>

好吧，我期望的是:

<input type="number">

基本上，问题是如何使用wtforms渲染input type="number".

Basically, the question is how can I render an input type="number" with wtforms.

推荐答案

首先，您的value应该是字段，而不是小部件.

First of all, your value should be a field, not a widget.

value = IntegerField(widget=NumberInput())

WTForms字段在调用时生成html，因此请尝试

WTForms fields generate html on call, so try

{{ form.value() }}
