基于modelform和ajax的注册

forms文件

创建ModelForm组件

from django import forms

from crm import models

from django.core.exceptions import ValidationError

import hashlib

#注册form

class RegForm(forms.ModelForm):

    #添加确认密码  按照form组件的样式写

    password = forms.CharField(widget=forms.PasswordInput(),required="不能为空",label="密码22",min_length="")

    re_password = forms.CharField(widget=forms.PasswordInput(),label="确认密码",min_length="")

    class Meta:

        #指定关联的model

        model=models.UserProfile

        #要展示的内容

        # fields="__all__"   #展示所有的字段

        # exclude=["is_active"] #排除这个字段

        #或者指定要显示的字段  决定了在页面上的显示顺序 ***  即使是自定义的re_password也可以写进来

        fields=["username","name","password","re_password","department","mobile"]

        #这个label的注释直接在modelform中改 或者 在model中写verbose_name="用户名"

        #这设置的label只对models里的字段起作用, 自己定义的re_password 不起作用

        labels={   #全局设置, 没有加label的字段就还是按数据库里的字段名

            "username":"用户名",

            "password":"密码",

            "name":"姓名",

            "department":"部门",

        }

        widgets = {

            # "password":forms.PasswordInput(attrs={"class":"form-control"})  #密码显示密文

        }

        # 单加的报错 只对title做设置

        error_messages = {

            "username":{"required":"不能为空","invalid":"格式错误"},

            "department":{"required":"不能为空"},

            "mobile":{"required":"不能为空"},

        }

    ##初始化把样式调出来

    def __init__(self,*args,**kwargs):

        super().__init__(*args,**kwargs)

        #调节样式

        print(self.fields) #拿到的是对象

        for field in self.fields.values(): #field 是取出来的对象

            field.error_messages={"required":"不能为空"}#批量处理

            field.widget.attrs.update({"class":"form-control"})

    def clean(self): #两次密码校验

        pwd = self.cleaned_data.get("password")

        re_pwd = self.cleaned_data.get("re_password")

        print(self.cleaned_data)

        if pwd == re_pwd and pwd:  #如果密码和确认密码一致, 并且存在

            # 两次密码一致 之后对密码进行加密

            md5 = hashlib.md5() # MD5对象

            md5.update(pwd.encode("utf-8")) #加密结果

            pwd = md5.hexdigest()

            print(pwd)  #3c4423d6a2f6dfcac2ad6f6d1981ad35

            self.cleaned_data["password"] = pwd

            print("-->",self.cleaned_data)

            #{'username': 'sanjiang@qq.com', 'name': 'sanjiang', 'password': '3c4423d6a2f6dfcac2ad6f6d1981ad35', 're_password': 'sanjiang', 'department': <Department: 销售部>, 'mobile': None}

            return self.cleaned_data

        else:

            self.add_error("re_password","两次密码不一致") #把错误提示加到re_password 容易取值

            raise ValidationError("两次密码不一致") #错误提示加到了所有的错误里了不容易取值

在views文件中利用modelform实例化

from django.shortcuts import render,HttpResponse,redirect

from crm.models import UserProfile

from crm.forms import RegForm

from django.http import JsonResponse

#注册 用ModelForm 和ajax

def reg(request):

    form_obj = RegForm()

    if request.method=="POST":

        form_obj = RegForm(request.POST) #用RegForm做校验

        res = {"user":None,"err_msg":""}

        if form_obj.is_valid(): #通过校验

            print('通过校验')

            print(form_obj.cleaned_data)

            #{'username': 'sanjiang@qq.com', 'name': 'sanjiang', 'password': '3c4423d6a2f6dfcac2ad6f6d1981ad35', 're_password': 'sanjiang', 'department': <Department: 销售部>, 'mobile': None}

            res["user"] = form_obj.cleaned_data.get("username")

            # 写入数据到数据库

            form_obj.cleaned_data.pop("re_password") #把re_password删除 因为没有在models的字段里

            # print(form_obj.cleaned_data)

            obj = UserProfile.objects.create(**form_obj.cleaned_data)

            # print(obj)

        else:

            # print("错误信息:",form_obj.errors)

            # print("部分干净信息:",form_obj.cleaned_data)

            res["err_msg"] = form_obj.errors

        return JsonResponse(res)

    return render(request,"reg.html",{"form_obj":form_obj})
