第一種自定義
獲取到表單的數(shù)據(jù)，自寫校驗(yàn)規(guī)則
第二種form插件的方式
定義校驗(yàn)類
class UserForm(forms.Form):
username = forms.CharField(label="用戶名", error_messages={"required": "用戶名必填"})
password = forms.CharField(label="密碼", error_messages={"required": "密碼必填"})
sms_code = forms.CharField(label="驗(yàn)證碼", error_messages={"required": "驗(yàn)證碼必填"})
使用校驗(yàn)類
@csrf_exempt
def login_handler(req):
if req.method == "POST":
user_form = UserForm(req.POST)
if user_form.is_valid():
user_obj = user_form.cleaned_data
is_auth = authenticate(username=user_obj.get("username"), password=user_obj.get("password"))
if is_auth and is_auth.is_active:
login(req, is_auth)
return HttpResponseRedirect('/')
else:
return render(req, "login.html", {"retcode": 1, "stderr": "用戶名或密碼不正確"})
else:
return render(req, "login.html", {"retcode": 1, "stderr": user_form.errors})
else:
return HttpResponseRedirect("/login")
前端接收返回錯誤提示

錯誤信息放在form之中仇箱，否則不會有提示

使用schedule等第三方的庫
from datetime import date
from marshmallow import Schema, fields, pprint
class ArtistSchema(Schema):
name = fields.Str()
class AlbumSchema(Schema):
title = fields.Str()
release_date = fields.Date()
artist = fields.Nested(ArtistSchema())
bowie = dict(name='David Bowie')
album = dict(artist=bowie, title='Hunky Dory', release_date=date(1971, 12, 17))
schema = AlbumSchema()
result = schema.dump(album)
pprint(result.data, indent=2)
# { 'artist': {'name': 'David Bowie'},
# 'release_date': '1971-12-17',
# 'title': 'Hunky Dory'}
