我想用Flask和WTForms建立一个网站。但是我无法使文本输入起作用(该页面不允许我在框中输入任何文本)。你能告诉我怎么了吗?
页面的外观如下:
这是我使用WTForms创建的表单
from flask_wtf import FlaskForm
from wtforms import SubmitField, IntegerField
from wtforms.validators import DataRequired, NumberRange, EqualTo
class RequestDataForm(FlaskForm):
feature_count = IntegerField('Number of features', validators=[DataRequired(), NumberRange(min=1, max=50)])
effective_rank = IntegerField('Effective Rank', validators=[DataRequired(), NumberRange(min=1, max=EqualTo(feature_count))])
noise = IntegerField('Noise', validators=[DataRequired(), NumberRange(min=0, max=1)])
submit = SubmitField('Submit')
这是layout.html
<!DOCTYPE html>
<html>
<style>
</style>
<head>
<!-- Required meta tags -->
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">

</head>
<body>
<main role="main" class="container">
<div class="row">
<div class="col-md-8">
{% with messages = get_flashed_messages(with_categories=true) %}
{% if messages %}
{% for category, message in messages %}
<div class="alert alert-{{ category }}">
{{ message }}
</div>
{% endfor %}
{% endif %}
{% endwith %}
{% block page_content %}{% endblock %}
</div>
</div>
</main>
</body>
</html>
这是我的page.html
{% extends 'layout.html' %}
{% block page_content %}
<div class="content-section">
<form method="POST" action="">
{{ form.hidden_tag() }}
<fieldset class="form-group">
<legend class="border-bottom mb-4">Fill with values.</legend>
<div class="form-group">
{{ form.feature_count.label(class="form-control-label") }}
{{ form.feature_count.label(class="form-control form-control-lg") }}
</div>
<div class="form-group">
{{ form.effective_rank.label(class="form-control-label") }}
{{ form.effective_rank.label(class="form-control form-control-lg") }}
</div>
<div class="form-group">
{{ form.noise.label(class="form-control-label") }}
{{ form.noise.label(class="form-control form-control-lg") }}
</div>
</fieldset>
<div class="form-group">
{{ form.submit(class="btn btn-outline-info") }}
</div>
</form>
</div>
{% endblock page_content%}
答案 0 :(得分:2)
根据您的HTML,您只为每个表单元素而不是元素本身输出label
。尝试将它们全部更新为:
<div class="form-group">
{{ form.noise.label(class="form-control-label") }}
{{ form.noise(class="form-control form-control-lg") }}
</div>
