烧瓶动态复选框

这非常简单:我有一个ID列表,我想将其作为一系列复选框显示给用户。用户应选择所需的内容,然后检查选择了哪些内容并执行功能。这是我的代码:

app.py:

getlisteUsers(): user{
    console.info('yess2')
    let data;
     this.http.get("http://localhost:8080/tests/getAll.php").pipe(
        tap(_=> this.log(`chargement de la liste réussit`)),
        catchError(this.handleError(`getlisteMotAApprendre`, [])))
    .subscribe(res => data = res);
    return data
}

和我的template.html:

from flask import Flask, render_template, flash, request, redirect
from wtforms import Form, TextField, TextAreaField, validators, StringField, SubmitField,widgets, SelectMultipleField
from flask_wtf import FlaskForm

app = Flask(__name__)
app.config.from_object(__name__)
@app.route("/example", methods=["GET", "POST"])
    def example():
      form = FlaskForm()
      ids= ['a','b','c']
      if request.method == 'POST':
          selected_ids = request.form.getlist("ids")
          if form.validate():
              flash('nice')
          else:
              flash('something went wrong')

      return render_template('example.html', form=form, ids= ids)

但是,这在我提交时会产生500错误。我要去哪里错了?十分感谢您的建议!
