werkzeug.routing.BuildError：無法為端點“auth.Esp_Index”構建 url。您的意思是“auth.login”嗎？

Question

我正在嘗試構建一個簡單的注冊和登錄表單，但我遇到了錯誤。 我試圖通過閱讀文檔來修復它，但沒有運氣。 你能幫忙嗎？

“werkzeug.routing.BuildError：無法為端點 'auth.Esp_Index' 構建 url。你的意思是 'auth.login' 嗎？”

init .py中的代碼

from flask import Flask
from flask_sqlalchemy import SQLAlchemy
from flask_login import LoginManager

db = SQLAlchemy()


def create_app():
    app = Flask(__name__)

    app.config['SECRET_KEY'] = '\xbd\xc5H\xe5\xd0rX\xcc\x11\x99'
    app.config['SQLALCHEMY_DATABASE_URI'] = 'postgresql://support:support@rea-lnx-tdin01:5432/postgres'

    db.init_app(app)

    from .auth import auth as auth_blueprint
    app.register_blueprint(auth_blueprint)
    return app

auth.py中的代碼

from flask import Blueprint, render_template, redirect

auth = Blueprint('auth',__name__)


@auth.route('/login', methods=["GET", "POST"])
def login():

Answer 1

When build a URL with url_for() in Flask, you should pass the endpoint of the view function, the default value of endpoint is the name of the view function , not the URL rule.

所以你應該在你的模板中寫下這個：

<a href="{{ url_for('auth.registration') }}" />
