博客园项目使用Form组件和Ajax实现注册需要注意的点

一.注册相关的知识点

首先是自己新建一个应用，users，然后在里面定义一个文件forms.py，然后在里面定义需要校验的字段和相应的钩子函数，关于forms组件，笔者在前一篇博客中详细地进行了说明，不清楚的同学可以去翻阅。forms.py如下：

# _*_ coding:utf-8 _*_


import re
from django import forms
from django.core.validators import RegexValidator
from django.forms import widgets, ValidationError
from .models import UserProfile


class RegisterForm(forms.Form):
    username = forms.CharField(
        required=True,
        min_length=6,
        max_length=15,
        error_messages={
            "required": "用户名不能为空",
            "min_length": "用户名长度不能小于6",
            "max_length": "用户名长度不能大于15"
        },
        widget=widgets.TextInput(attrs={"placeholder": "请输入您的用户名", "class": "form-control"})
    )
    password = forms.CharField(
        required=True,
        min_length=6,
        max_length=30,
        error_messages={
            "required": "密码不能为空",
            "min_length": "密码长度不能小于6",
            "max_length": "密码长度不能超过30",
        },
        widget=widgets.PasswordInput(attrs={"placeholder": "请输入密码", "class": "form-control"})
    )
    password_again = forms.CharField(
        required=True,
        min_length=6,
        max_length=30,
        error_messages={
            "required": "密码不能为空",
            "min_length": "密码长度不能小于6",
            "max_length": "密码长度不能超过30",
        },
        widget=widgets.PasswordInput(attrs={"placeholder": "请再次输入您的密码", "class": "form-control"})
    )

    email = forms.EmailField(
        required=True,
        error_messages={
            "required": "邮箱不能为空",
            "invalid": "邮箱格式错误",
        },
        widget=widgets.EmailInput(attrs={"placeholder": "请输入您的邮箱", "class": "form-control"})
    )

    mobile = forms.CharField(
        required=True,
        max_length=11,
        min_length=11,
        error_messages={
            "required": "手机号码不能为空",
            "min_length": "手机号码长度必须是11位",
            "max_length": "手机号码长度必须是11位",
        },
        validators=[RegexValidator("\d+", "手机号码只能是数字")],
        widget=widgets.TextInput(attrs={"placeholder": "请您输入你的手机号码", "class": "form-control"})
    )

    def clean_username(self):
        name = self.cleaned_data.get("username")
        is_exist = UserProfile.objects.filter(username=name).exists()
        if is_exist:
            raise ValidationError("抱歉，用户名已经存在")
        return name

    def clean_password(self):
        """
        再加入一个判断，不能是纯数字或者纯字母
        """
        password = self.cleaned_data.get("password")
        result = re.findall("(?=^.{8,}$)((?=.*\d)|(?=.*\W+))(?![.\n])(?=.*[A-Z])(?=.*[a-z]).*$", password)
        if result:
            return password
        else:
            raise ValidationError("密码必须包含大小写，长度至少为8")

    def clean(self):
        if self.cleaned_data.get("password") == self.cleaned_data.get("password_again"):
            return self.cleaned_data
        else:
            raise ValidationError("对不起，两次输入的密码不一致")
