如何在web.py中使用POST方法更新postgreSQL数据库中的表？

Question

Here's my web.py code so far. I want to use my web server to update a table.

import web


urls = ('/', 'Index')

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

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

web.config.debug = True

db = web.database(dbn='postgres', db='my_db', user='postgres', pw='******', host='localhost')

class Index:

    def GET(self):
        drivers = db.select("drivers")
        return render.index(drivers)

    def POST(self, name):
        return "post"

if __name__ == '__main__':app.run()

Right now it takes what's in the table and prints it out in the browser. But I want to implement some logic that adds numeric values to the table as a while loop runs using the post method. How can I do this?

You can do the Postgres insertion as follows,

def POST(self):
    sequence_id = db.insert('test1', col1=5, col2=3)  # insert(tablename, seqname=None, _test=False, **values)

Refer this for more details.

You may use,

data = json.loads(web.data()) # convert to dictionary if needed using json.loads

or

data = web.input().number # number is the key which holds the data

depending on how you send data to POST method.

eg: If content-type = application/json use web.input().number

Refer this as well.
