实现：表单验证

工程示例：

urls.py

from django.conf.urls import urlfrom django.contrib import adminfrom app01 import viewsurlpatterns = [    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 renderfrom django.shortcuts import redirectfrom django.shortcuts import HttpResponsefrom app01 import modelsfrom django import formsfrom django.forms import fieldsclass 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(        required=True,        min_length=32    )    age = fields.IntegerField(        required=True,        error_messages={            'required': '邮箱不能为空',            'invalid': '邮箱格式错误',        }    )    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})

f1.html

    
         
     
    
      
用户{
    { obj.user }}{
    { obj.errors.user.0 }}
    
      
密码{
    { obj.pwd }}{
    { obj.errors.pwd.0 }}
    
      
年龄{
