jinja2 模板使用

task

有时候需要把数据（比如csv，或者\t分割）转换成html，方便查看。

jinja安装

pip install Jinja2
doc: http://docs.jinkan.org/docs/jinja2/index.html

过程

demo数据

1，2，3，4，5
6，7，8，9，10

把这两行数据渲染在表格里

1. 创建your_template.html

    
        
        
        
    
    
        
            {% for item in data %}
            
            {% endfor %}
        

            

                

                    mt
                
                

                    flow
                
                

                    总消费
                
                

                    关闭消费
                
                

                    关闭占比
                
                

                    打开占比
                
            

                

                    {{ item[0] }}
                
                

                    {{ item[1] }}
                
                

                    {{ item[2] }}
                
                

                    {{ item[3] }}
                
                

                    {{ item[4] }}
                
                

                    {{ item[5] }}
                
            
    

2. html生成脚本gen_html.py

 # encoding=utf-8
 import sys
 from jinja2 import Environment, FileSystemLoader

 env = Environment(loader=FileSystemLoader('./', encoding='utf-8'))

 data = []
 with open('./data') as f:
     for line in f:
         line = line.decode('gb18030', 'ignore').strip()
         cols = line.split(u'\t')
         data.append(cols)

 template = env.get_template('your_template.html')
 html = template.render(date=date, encoding='utf-8', data=data)  # unicode string
 print >> sys.stdout, html.encode('utf-8', 'ignore')

3. email

 python gen_html.py > temp.html

 email_to="[email protected]"
 /usr/lib/sendmail -t <<< "To: $email_to
 From: [email protected]
 Subject: demo
 Content-type: text/html; charset=utf-8
 $(cat temp.html)
 "
