“NameError: name 'redirect' is not defined”，即使导入了重定向

Question

I have this simple Flask 1.1.x app:

from flask import Flask
from flask import redirect, render_template, url_for

app = Flask(__name__)


@app.route('/', methods=['GET'])
def index():
    return render_template("index.html")
    
@app.route('/donate', methods=['GET'])
def donate():
    return render_template("donate.html")

@app.route('/donations', methods=['GET'])
def donations():
    return redirect(url_for('donate'))


if __name__ == '__main__':
    app.run(host='localhost', port=8080, debug=True)

I'm developing on a local server. When I attempt to access /donations in a browser, I get an Internal Server Error and the local server reports this error:

ERROR in app: Exception on /donations [GET]
<trimmed>
    return redirect(url_for('donate'))
NameError: name 'redirect' is not defined

I don't understand why it's reporting redirect as undefined, since I am importing it and I'm calling it the same way the Flack Quickstart Guide does.

Answer 1

Could you replace return redirect(url_for('donate')) with return redirect('/donate') ?
