Question

我想在以下index.html页面的<td>中显示数据库中的每一行：

$def with(items)
<h1></h1>
<br/>
<br>
<table border="1">
    <tr>
        <th>Name</th>
        <th>address</th>
        <th>number</th>
    </tr>

    <tr>
        <td>//want name here</td>
        <td>//address here</td>
        <td>//number here</td>
    </tr>
</table>

app.py代码：

import web
import MySQLdb

urls = (
  '/', 'Index'
)

app = web.application(urls, globals())

render = web.template.render('templates/')

class Index(object):
    def GET(self):
        return render.hello_form()

    def POST(self):
            form = web.input(name="a", newname="s", number="d")
            conn = MySQLdb.connect(host= "localhost", user="root", passwd="", db="testdb")
            x = conn.cursor()
            x.execute("SELECT * FROM details  WHERE name = '%s'" % (form.name))
            conn.commit()
            items = x.fetchall()
            for row in items: 
                conn.rollback()
                conn.close()
                return render.index(items)
    if __name__ == "__main__":
        app.run()

项（获取的结果）将是一个元组数组。按原样返回数组，在html上显示整个数据，HTML只渲染一次。

app.py代码

import web
import MySQLdb

urls = (
  '/', 'Index'
)

app = web.application(urls, globals())

render = web.template.render('templates/')

class Index(object):
    def GET(self):
        return render.hello_form()

def POST(self):
        form = web.input(name="a", newname="s", number="d")
        conn = MySQLdb.connect(host= "localhost", user="root", passwd="", db="testdb")
        x = conn.cursor()
        x.execute("SELECT * FROM details  WHERE name = '%s'" % (form.name))
        items = x.fetchall()       
        conn.close()
        return render.index(items) // return the array of results as a whole
if __name__ == "__main__":
    app.run()

在index.html上

$def with(items)
<h1></h1>
<br/>
<br>
<table border="1">
    <tr>
        <th>Name</th>
        <th>address</th>
        <th>number</th>
    </tr>
   $for row in items: 
        <tr>
        <td>$row[0]</td>
        <td>$row[1]</td>
        <td>$row[2]</td>
        </tr>
</table>

Iterate over the items and display them
