针对一个实例：注册用户讲解。
模型：models.py
class UserInfo(models.Model):
    name=models.CharField(max_length=32)
    pwd=models.CharField(max_length=32)
    email=models.EmailField()
    tel=models.CharField(max_length=32)
    
模板: register.html:
<!DOCTYPE html>
<html lang="en">
    <head>
        <meta charset="UTF-8">
        <title>Title</title>
    </head>
    <body>
    <form action="" method="post">
        {% csrf_token %}
        <div>
            <label for="user">用户名</label>
            <p><input type="text" name="name" id="name"></p>
        </div>
        <div>
            <label for="pwd">密码</label>
            <p><input type="password" name="pwd" id="pwd"></p>
        </div>
        <div>
            <label for="r_pwd">确认密码</label>
            <p><input type="password" name="r_pwd" id="r_pwd"></p>
        </div>
         <div>
            <label for="email">邮箱</label>
            <p><input type="text" name="email" id="email"></p>
        </div>
        <input type="submit">
    </form>
    </body>
</html>

视图函数：register
# forms组件
from django.forms import widgets
wid_01=widgets.TextInput(attrs={"class":"form-control"})
wid_02=widgets.PasswordInput(attrs={"class":"form-control"})

class UserForm(forms.Form):
    name=forms.CharField(max_length=32,
                         widget=wid_01
                         )
    pwd=forms.CharField(max_length=32,widget=wid_02)
    r_pwd=forms.CharField(max_length=32,widget=wid_02)
    email=forms.EmailField(widget=wid_01)
    tel=forms.CharField(max_length=32,widget=wid_01)

def register(request):

    if request.method=="POST":
        form=UserForm(request.POST)
        if form.is_valid():
            print(form.cleaned_data)       # 所有干净的字段以及对应的值
        else:
            print(form.cleaned_data)       #
            print(form.errors)             # ErrorDict : {"校验错误的字段":["错误信息",]}
            print(form.errors.get("name")) # ErrorList ["错误信息",]
        return HttpResponse("OK")
    form=UserForm()
    return render(request,"register.html",locals())
