Revision as of 23:34, 25 January 2013

The word yes is printed to screen. User votes 'yes', 'no', or 'maybe'. For each 'maybe' the word gets x amount bigger. For each 'yes' it gets twice that amount bigger. Each no is counted as zero and does not affect the size.

Code

Make db

Make a db to count the votes. Run once.

#!/usr/bin/python
#-*- coding:utf-8 -*-

import pymongo
from pymongo import Connection
 
connection = Connection()
myDB = connection['yes1']
collection = myDB.collection 

# create db entry to track votes, starting at zero.
entry = {'title': 'yesVotes', 'tally': 0 }
collection.insert(entry)

Voting interface

Display the word 'YES', with css properties determined by tally in db.

import cgi

import random
 
#========= get votes tally from db

connection = Connection()
myDB = connection['yes1']
collection = myDB.collection 

entry = myDB.collection.find({'title': 'yesVotes'})
tally = entry[0]['tally']				# entry[0] is the hash in our db. Grab value of 'tally' from the hash.

cssOpacity = float(tally) * 0.001
cssFontsize = float(tally) * 0.0001


#========= display the word styled according to no. of votes
