Detailed explanation of the use of Django controls and parameter passing

This time I will bring youdjangoControland detailed explanation of the use of passing parameters. What are theprecautionsfor using Django controls and passing parameters? Here is the actual combat Let’s take a look at the case.

This article introduces the single selection and multi-selection in the djangoHTML form control, and explains how to pass parameters.

1. Form controls in HTML:

Forms are generally written in HTML as:

 这个method代表方法，方法一般有两个一个是'post'，一个是'get'，action是提交表单到何处，可填写一个网址。不填则默认到本页面。 {%csrf_token%} 这个是django中的一个标签，用于防止恶意攻击使用，如果不加入这个标签，会遇到不能提交的问题，处理麻烦一点，建议加上。 这就是一个单选标签，多选为type='checkbox'。 value是显示的内容，并且后端提交后也将此作为值，其中name是后端 获取时所用的如后端使用 select = request.POST['select']获取这个单选按钮的value，另外也可以用select = request.POST.get('select',None)来获取。 这就是一个提控件，其中的type='submit'会保证点击后表单（
）中的内容被提交到后端。 一个输入框  

The overall structure of the previous paragraph in HTML is

     
  
 {%csrf_token%}    
  

Then the previous HTML is like this.

2. Accept data in django’s view.py:

The backend can write a def in the view to accept the data passed in by the frontend:

Such as:

def receive_data(request): if request.POST: # 如果数据提交 print('有提交') select = request.POST.get('select',None) text = request.POST.get('text',None) print(select,text) return render(request,'your_html.html', locals()) # your_html.html改为你的html页面并且参考前面的博客建立url链接。

This is a simple case of django creation before and after interaction, conducted under django 1.10.5python3.5 html 5.
