一、切入點(diǎn)使用form
讓頁(yè)面生成寫好的表單，從form切入，注冊(cè)用戶名，昵稱，密碼，確認(rèn)密碼，郵箱，驗(yàn)證碼
-
常用的函數(shù)
-
{{obj_register.non_field_errors.0}}顯示all
-
from django.core.validators import RegexValidator用來寫正則的
-
from django.core.exceptions import ValidationError用來捕獲clean異常的
-
from django import forms 用來繼承的
-
from django.forms import fields 用來調(diào)用字段的
-
from django.forms import widgets 用來引入頁(yè)面插件的
-
注意點(diǎn)
-
驗(yàn)證碼判斷
首先我們將驗(yàn)證是儲(chǔ)存在session中，而session是在request中，這里我們需要構(gòu)造一個(gè)繼承的函數(shù)，給我們form表單函數(shù)加入一個(gè)屬性
class Base(object):
def __init__(self,request,*args,**kwargs):
self.request = request
super(Base,self).__init__(*args,**kwargs)
-
clean_name 重寫
- 用戶名、郵箱、判斷是結(jié)合數(shù)據(jù)庫(kù)查找判斷是否存在
- 驗(yàn)證碼是去session判斷
-
多字段判斷clean
- 判斷兩次輸入的密碼是否正確使用clean
當(dāng)我們想給某個(gè)字段加上額外的判斷時(shí)候，一定要重寫clean_name -
widgets.TextInput 為標(biāo)簽屬性賦值
-
widgets.CheckboxInput({'value':"0"})，checkbox設(shè)置
