flask简单的注册功能

from datetime import datetime
from app import db


# 会员
class User(db.Model):
    __tablename__ = "user"
    id = db.Column(db.Integer, primary_key=True)  # 编号
    name = db.Column(db.String(100), unique=True)  # 昵称
    pwd = db.Column(db.String(100))  # 密码
    email = db.Column(db.String(100), unique=True)  # 邮箱
    phone = db.Column(db.String(11), unique=True)  # 手机号码
    info = db.Column(db.Text)  # 个性简介
    face = db.Column(db.String(255), unique=True)  # 头像
    addtime = db.Column(db.DateTime, index=True, default=datetime.now)  # 注册时间
    uuid = db.Column(db.String(255), unique=True)  # 唯一标志符
    userlogs = db.relationship('Userlog', backref='user')  # 会员日志外键关系关联
    comments = db.relationship('Comment', backref='user')  # 评论外键关系关联
    moviecols = db.relationship('Moviecol', backref='user')  # 收藏外键关系关联

    def __repr__(self):
        return "<User %r>" % self.name

    # 检查密码匹配
    def check_pwd(self, pwd):
        from werkzeug.security import check_password_hash
        return check_password_hash(self.pwd, pwd)

第一步：定制forms表单

from flask_wtf import FlaskForm
from wtforms import StringField, PasswordField, SubmitField
from wtforms.validators import DataRequired, EqualTo


class RegistForm(FlaskForm):
    name = StringField(
        label="昵称",
        description="昵称",
        validators=[
            DataRequired("请输入昵称"),
        ],
        render_kw={
            "class": "form-control input-lg",
            "placeholder": "昵称",
        }
    )
    email = StringField(
        label="邮件",
        description="邮件",
        validators=[
            DataRequired("请输入邮件"),
        ],
        render_kw={
            "class": "form-control input-lg",
            "placeholder": "邮件",
        }
    )
    phone = StringField(
        label="电话",
        description="电话",
        validators=[
            DataRequired("请输入电话"),
        ],
        render_kw={
            "class": "form-control input-lg",
            "placeholder": "电话",
        }
    )
    pwd = PasswordField(
        label="密码",
        description="密码",
        validators=[
            DataRequired("请输入密码"),
        ],
        render_kw={
            "class": "form-control input-lg",
            "placeholder": "密码",
        }
    )
    repwd = PasswordField(
        label="",
        description="",
        validators=[
            DataRequired("请再次输入密码"),
            EqualTo("pwd", message="前后密码不一致"),
        ],
        render_kw={
            "class": "form-control input-lg",
            "placeholder": "再次输入密码",
        }
    )
    submit = SubmitField(
        label="注册",
        render_kw={
            "class": "btn btn-lg btn-success btn-block",
        }
    )
    def validate_phone(self, field):
        phone = field.data
        rex = "1[358]\d{9}"
        if not re.findall(rex, phone):
            raise ValidationError("手机格式不正确")

第二步：改造html模板

 <form role="form" method="post" action="{{ url_for('home.regist') }}">
                        <fieldset>
                            <div class="form-group">
                                <label for="input_name"><span
                                        class="glyphicon glyphicon-user"></span>&nbsp;{{ form.name.label }}</label>
                                {{ form.name }}
                            </div>
                            {% for err in form.name.errors %}
                                <div class="col-md-12" id="error_name">{{ err }}</div>
                            {% endfor %}
                            <div class="form-group">
                                <label for="input_email"><span
                                        class="glyphicon glyphicon-envelope"></span>&nbsp;{{ form.email.label }}</label>
                                {{ form.email }}
                            </div>
                            {% for err in form.email.errors %}
                                <div class="col-md-12" id="error_email">{{ err }}</div>
                            {% endfor %}
                            <div class="form-group">
                                <label for="input_phone"><span
                                        class="glyphicon glyphicon-phone"></span>&nbsp;{{ form.phone.label }}</label>
                                {{ form.phone }}
                            </div>
                            {% for err in form.phone.errors %}
                                <div class="col-md-12" id="error_phone">{{ err }}</div>
                            {% endfor %}
                            <div class="form-group">
                                <label for="input_password"><span
                                        class="glyphicon glyphicon-lock"></span>&nbsp;{{ form.pwd.label }}</label>
                                {{ form.pwd }}
                            </div>
                            {% for err in form.pwd.errors %}
                                <div class="col-md-12" id="error_password">{{ err }}</div>
                            {% endfor %}
                            <div class="form-group">
                                <label for="input_repassword"><span
                                        class="glyphicon glyphicon-lock"></span>&nbsp;{{ form.repwd.label }}</label>
                                {{ form.repwd }}
                            </div>
                            {% for err in form.repwd.errors %}
                                <div class="col-md-12" id="error_repassword">{{ err }}</div>
                            {% endfor %}
                            {{ form.submit }}
                            {{ form.csrf_token }}
                        </fieldset>
                    </form>

第三步：接收post请求数据存入数据库

from . import home
from flask import render_template, redirect, url_for, flash
from .forms import RegistForm
from werkzeug.security import generate_password_hash
from app.models import User
from app import db

@home.route("/regist/", methods=["GET", "POST"])
def regist():
    form = RegistForm()
    if form.validate_on_submit():
        data = form.data
        name = data.get("name")
        email = data.get("email")
        phone = data.get("phone")
        pwd = generate_password_hash(data.get("pwd"))
        user = User(
            name=name,
            email=email,
            phone=phone,
            pwd=pwd,
        )
        db.session.add(user)
        db.session.commit()
        flash("注册成功", "ok")
        return redirect(url_for('home.login'))
    return render_template("home/regist.html", form=form)
