【问题描述】：
我想使用 Flask 在我的网站上为每个注册用户创建一个独特的个人资料页面。目前，我的个人资料页面代码是这样的：
@app.route('/profile/')
def profile():
if 'email' not in session:
return redirect(url_for('signin'))
user = User.query.filter_by(email = session['email']).first()
if user is None:
return redirect(url_for('signin'))
else:
return render_template('profile.html')
但是，当我尝试改变时
@app.route('/profile/<lastname>')
def profile(lastname):
我收到 werkzeug.routing.BuildError。我的问题是，我是否在为每个用户创建一个独特的个人资料页面的正确轨道上，如果是这样，我怎样才能将变量添加到我的 url，这样我就不会收到 BuildError？谢谢您的帮助。
这是完整的 routes.py 代码：
from intro_to_flask import app
from flask import Flask, render_template, request, flash, session, redirect, url_for
from forms import ContactForm, SignupForm, SigninForm
from flask.ext.mail import Message, Mail
from models import db, User
mail = Mail()
@app.route('/')
def home():
return render_template('home.html')
@app.route('/about')
def about():
return render_template('about.html')
@app.route('/contact', methods=['GET', 'POST'])
def contact():
form = ContactForm()
if request.method == 'POST':
if form.validate_on_submit() == False:
return render_template('contact.html', form=form)
else:
name = request.form['name']
subject = request.form['subject']
senderEmail = request.form['email']
message = request.form['message']
msg = Message(subject, sender = senderEmail, recipients= ['myemailaddress@gmail.com'])
msg.body = message + "\n\n" + name + " (" + senderEmail + ")"
mail.send(msg)
return render_template('contact.html', success=True)
elif request.method == 'GET':
return render_template('contact.html', form=form)
@app.route('/signup', methods = ['GET', 'POST'])
def signup():
form = SignupForm()
if 'email' in session:
return redirect(url_for('profile'))
if request.method == 'POST':
if form.validate() == False:
return render_template('signup.html', form = form)
else:
newuser = User(form.firstname.data, form.lastname.data, form.email.data, form.password.data)
db.session.add(newuser)
db.session.commit()
session['email'] = newuser.email
return redirect(url_for('profile'))
elif request.method == 'GET':
return render_template('signup.html', form = form)
@app.route('/profile/')
def profile():
if 'email' not in session:
return redirect(url_for('signin'))
user = User.query.filter_by(email = session['email']).first()
if user is None:
return redirect(url_for('signin'))
else:
return render_template('profile.html')
@app.route('/signin', methods=['GET', 'POST'])
def signin():
form = SigninForm()
if 'email' in session:
return redirect(url_for('profile'))
if request.method == 'POST':
if form.validate() == False:
return render_template('signin.html', form=form)
else:
session['email'] = form.email.data
return redirect(url_for('profile'))
elif request.method == 'GET':
return render_template('signin.html', form = form)
@app.route('/signout')
def signout():
if 'email' not in session:
return redirect(url_for('signin'))
session.pop('email', None)
return redirect(url_for('home'))
我相信 BuildError 来自我调用 url_for('profile') 但我的配置文件函数将 lastname 作为参数并且它没有反映在我的 url_for 命令中。我只是不确定应该在我的 url_for 方法中包含什么参数。
这是我的 models.py 的代码：
from flask.ext.sqlalchemy import SQLAlchemy
from werkzeug import generate_password_hash, check_password_hash
db = SQLAlchemy()
class User(db.Model):
__tablename__ = 'users'
uid = db.Column(db.Integer, primary_key = True)
firstname = db.Column(db.String(100))
lastname = db.Column(db.String(100))
email = db.Column(db.String(120), unique = True)
pwdhash = db.Column(db.String(54))
def __init__(self, firstname, lastname, email, password):
self.firstname = firstname.title()
self.lastname = lastname.title()
self.email = email.lower()
self.set_password(password)
def set_password(self, password):
self.pwdhash = generate_password_hash(password)
def check_password(self, password):
return check_password_hash(self.pwdhash, password)

问题不在您显示的代码中，您必须在忘记添加
lastname参数的地方调用url_for()。
