第一步：定制forms表单

# -*- coding: utf-8 -*-# @Author: Laifrom flask_wtf import FlaskFormfrom wtforms import StringField, PasswordField, SubmitFieldfrom wtforms.validators import DataRequired, EqualToclass 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.name.label }}                                {
   { form.name }}                            
      
                            {% for err in form.name.errors %}                                
      
       {
   { err }}
      
                            {% endfor %}                            
      
                                
        {
   { form.email.label }}                                {
   { form.email }}                            
      
                            {% for err in form.email.errors %}                                
      
       {
   { err }}
      
                            {% endfor %}                            
      
                                
        {
   { form.phone.label }}                                {
   { form.phone }}                            
      
                            {% for err in form.phone.errors %}                                
      
       {
   { err }}
      
                            {% endfor %}                            
      
                                
        {
   { form.pwd.label }}                                {
   { form.pwd }}                            
      
                            {% for err in form.pwd.errors %}                                
      
       {
   { err }}
      
                            {% endfor %}                            
      
                                
        {
   { form.repwd.label }}                                {
   { form.repwd }}                            
      
                            {% for err in form.repwd.errors %}                                
      
       {
   { err }}
      
                            {% endfor %}                            {
   { form.submit }}                            {
   { form.csrf_token }}                        
     
                    
    

第三步：接收post请求数据存入数据库

from . import homefrom flask import render_template, redirect, url_for, flashfrom .forms import RegistFormfrom werkzeug.security import generate_password_hashfrom app.models import Userfrom 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)
