如何将数据从一条路线传输到烧瓶中的另一条路线

Question

I'm having some trouble transferring info from a form from one route (main) to another route (score)
this is my main route calling the form

@main.route('/', methods=['GET', 'POST'])
def root():
    form = form()
    if form.validate_on_submit():
        form_data = form.score.data
        return redirect(url_for('main.score', form_data=form_data))
    return render_template('root.html', form=form)

and in the score layout i have this

{% extends 'layout.html' %}

{% block content %}
    <p>{{ form_data.score }}</p>
{% endblock content %}

i want it to display the score that the user inputs into the form
and i keep getting this error:

jinja2.exceptions.UndefinedError: 'form_data' is undefined

您应该只呈现分数模板，而不是尝试重定向到它：

return render_template('score.html', form_data=form_data)
