工程示例：
urls.py
from django.conf.urls import url
from django.contrib import admin
from app01 import views
urlpatterns = [
url(r'^admin/', admin.site.urls),
url(r'^f1.html$', views.f1),
]
settings.py
STATIC_FILES_DIRS = ( os.path.join(BASE_DIR,'static'), )
views.py
from django.shortcuts import render
from django.shortcuts import redirect
from django.shortcuts import HttpResponse
from app01 import models
from django import forms
from django.forms import fields
class F1Form(forms.Form):
user = fields.CharField(
max_length=18,
min_length=6,
required=True,
error_messages={'required': '用户名不能为空',
'max_length': '太长了',
'min_length': '太短了'
}
)
pwd = fields.CharField(

)
age = fields.IntegerField(

error_messages={
'required': '邮箱不能为空',

}
)
email = fields.EmailField(
required=True,
min_length=8
)
def f1(request):
if request.method == 'GET':
obj = F1Form()
return render(request, 'f1.html', {'obj': obj})
else:
obj = F1Form(request.POST)
# 是否全部验证成功
if obj.is_valid():
# 用户提交的数据
print('验证成功', obj.cleaned_data)
return redirect('http://www.baidu.com')
else:
print('验证失败', obj.errors)
return render(request, 'f1.html', {'obj': obj})
