from . import home
from flask import render_template, redirect, url_for, flash
from .forms import RegisterForm
from app.models import User
from werkzeug.security import generate_password_hash
from app import db
import uuid
@home.route('/register/', methods=['GET', 'POST'])
def register():
form = RegisterForm()
if form.validate_on_submit():
data = form.data
user = User(
name=data['name'],
pwd=generate_password_hash(data['pwd']),
email=data['email'],
phone=data['phone'],
uuid=uuid.uuid4().hex
)
db.session.add(user)
db.session.commit()
flash('注册成功', category='ok')
return redirect(url_for('home.register'))
return render_template('home/register.html', form=form)
修改register.html会员注册模板
{% with msgs = get_flashed_messages(category_filter=['ok']) %}
{% if msgs %}
{% for msg in msgs %}
{{ msg }}
