首先HTML效果圖：
HTML程式碼：
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>註冊內容驗證</title> </head> <body> <form action="/register/" method="post" novalidate> <p>username:{{ obj.username }}{{ obj.errors.username.0 }}</p> <p>password:{{ obj.password }}{{ obj.errors.password.0 }}</p> <p>age:{{ obj.age }}{{ obj.errors.age.0 }}</p> <p>email:{{ obj.email }}{{ obj.errors.email.0 }}</p> <p>address:{{ obj.address }}{{ obj.errors.address.0 }}</p> <p>{{ obj.gender }}</p> <p>{{ obj.users }}</p> <p>{{ obj.myaddrs }}</p> <p><input type="submit" value="提交"><input type="reset" value="重置"> </p> </form> </body> </html>
後臺Veiws程式碼：
from django.shortcuts import render,redirect from django import forms from django.forms import widgets # Create your views here. #建立Form驗證類，繼承forms.Form class RegisterForm(forms.Form): username = forms.CharField(max_length=32,min_length=12,required=True,error_messages={ "max_length":"長度必須為6~12", "min_length":"長度必須為6~12", "required":"使用者名稱不能為空", }) password = forms.CharField(required=True,error_messages={ "required":"密碼不能為空！" }) age = forms.IntegerField(required=True,error_messages={ "required": "密碼不能為空！", "invalid":"年齡必須為數字！" }) email = forms.EmailField(required=True,error_messages={ "required": "郵箱不能為空！", "invalid": "郵箱格式不正確！" }) address = forms.CharField( initial=2, widget = widgets.Select(choices=((1,"北京"),(2,"上海"),(3,"深圳"),)) ) gender = forms.ChoiceField( choices=((0,"男"),(1,"女")), widget=widgets.RadioSelect, initial=0 ) #多選select，值為列表 users = forms.MultipleChoiceField( choices=((1,'上海'),(2,'北京'),(3,"深圳")), initial=[2,], #可以加屬性 widget=widgets.SelectMultiple(attrs={"class":"ray"}) ) myaddrs = forms.MultipleChoiceField( choices=((1, '上海'), (2, '北京'), (3, "深圳")), initial=3, widget=widgets.CheckboxSelectMultiple ) def register(request): if request.method=="GET": obj = RegisterForm() return render(request,"registervalid.html",{"obj":obj}) else: #將表單值獲取到 傳入Form引數 obj = RegisterForm(request.POST) if obj.is_valid(): print("驗證成功！",obj.cleaned_data) return redirect("Http://www.baidu.com") else: print("驗證失敗！",obj.errors) return render(request,"registervalid.html",{"obj":obj})
