我创建了一个html表单，包括6个滑块和一个提交按钮。我想将滑块的值作为整数值到我的烧瓶应用程序中
<form id="upload-form" action="{{ url_for('index') }}" method="POST" enctype="multipart/form-data">
<fieldset>
<!-- Hospital Slider -->
<div class="col-md-4">
<h4>Hospital Services</h4>
</div>
<div class="col-md-8">
<div class="""slidecontainer">
<input type="range" min="0" max="100" value="50" class="slider" id="sliderHospital">
<br>
</div>
</div>
<!-- Ambulance Slider -->
<div class="col-md-4">

这是我的烧瓶应用程序代码
from flask import Flask, render_template, request
from flask_wtf import FlaskForm
from wtforms import StringField, IntegerRangeField, PasswordField, TextAreaField, TextField, RadioField, SelectField, FileField, IntegerField, DateField
from wtforms.validators import InputRequired
import os
import os
app = Flask(__name__)
app.debug=True
app.config['SECRET_KEY'] = 'Thisisasecret!'
APP_ROOT = os.path.dirname(os.path.abspath(__file__))
class TestForm(FlaskForm):
sliderHospital = DecimalRangeField('Hospital', default=0)
@app.route('/')
def index():
return render_template('index.php')
if __name__=="__main__":
app.run()
当我运行应用程序时出现此错误
ImportError：无法导入名称IntegerRangeField
我想从表单中获取值，并将它们保存为烧瓶应用程序中的6个单独变量。我错过了什么吗？
您应该为每个范围类型输入命名。您可以从烧瓶请求中获取输入值。
演示：
<html>
<head></head>
<body>
<form method="POST" action="test">
<input type="range" min="0" max="100" name="name_of_slider" />
<input type="submit" value="submit" />
</form>
</body>
</html>
from flask import request
@app.route("/test", methods=["POST"])
def test():
name_of_slider = request.form["name_of_slider"]
return name_of_slider
