Generating an HTML input tag from a Django Froms module
First create a forms.py file under the current application
Vim forms.py
From Django Import forms
def forms. Adminform (forms. Form):
Username = forms. Charfield () #生成明文的输入框
Password = forms. Charfield (Widget=forms.widgets.passwordinput)
#生成一个密文显示的输入框
Password = forms. Charfield (Widget=forms.widgets.passwordinput (attrs={' class ': ' Auto '})
(Attrs={' class ': ' Auto '}) #定义标签属性
Email1 = forms. Charfield (Widget=forms.widgets.emailinput)
EMAIL2 = forms. Emailfield ()
#widget类型是通过正则表达式来判定的
Views.py write a method for generating the input tag of the forms module
def index2 (Request):
if Request.method = = ' POST ':
#判断在html表单里面提交的方式是什么 (typically 2 way post and get)
form = forms. Adminform (Request. POST)
A class in the #AdminForm是在froms. PY, invoked through the forms method and assigned to a form
If Forms.is_valid ():
#判断是否合法, the error message will be prompted on the front page of the wrong input
data = Form.cleaned_data #请求通过接受该数据
m = Adminform (username= ' Tom ', password= ' tom123 ')
#AdminForm里面提交数据, and save
M.save ()
else: #如果输入规则不匹配在前台显示错误信息
Print Form.erros.as_data ()
Print Form.erros.as_json ()
Print Form.erros.as_text ()
Common error message Formats
Else
form = forms. Adminform ()
#判断如果不是post方法提交的
return render_to_response (' index2.html ', {' Model ': form})
#把结果返回给前端的index2. Html,model is a variable inside the front index2.html that accepts data returned in the background, and the form is the real data
3.index2.html Content
<meta http-equiv= "Content-type" content= "text/html"/>
<title></title>
<body>
<form action= '/index2/' method= ' POST ' >
<p> User name:{{model.username}}</p>
<p> Password:{{model.password}}</p>
<p> Email:{{model.email}}</p>
<input type= ' Submit ' value= ' submission '/>
</form>
</body>
After the optimization, more concise save a lot of HTML code
<meta http-equiv= "Content-type" content= "text/html"/>
<title></title>
<body>
<form action= '/index2/' method= ' POST ' >
{{model.as_table}} has been shown in table Form
{{Model.as_ul}} has been shown in UL form
#具体查看form父类里面的详细方法---source code
#好处省代码
#坏处样式不可控
<input type= ' Submit ' value= ' submission '/>
</form>
</body>
