Using StringListProperty efficently in Google App Engine


StringListProperty is a datastore value type that stores list items. Using StringListProperty is very easy:

#!/usr/bin/env python
from google.appengine.ext import webapp
from google.appengine.ext.webapp import util
from google.appengine.ext import db

class Page(db.Model):
    title=db.StringProperty(multiline=False)
    keywords=db.StringListProperty()

class MainHandler(webapp.RequestHandler):
    def get(self):
        newpage=Page()
	newpage.title="Suat ATAN's books"
        newpage.keywords=["book","author"]
        newpage.put()

	newpage=Page()
	newpage.title="Suat ATAN's life"
        newpage.keywords=["canada","author"]
        newpage.put()

	newpage=Page()
	newpage.title="Suat ATAN's gusto"
        newpage.keywords=["coffe","pizza"]
        newpage.put()

	pages=Page().all().filter("keywords" = "author")
	for page in pages:
	    print i.title+"--"+i.keywords

def main():
    application = webapp.WSGIApplication([('/', MainHandler)],
                                         debug=True)
    util.run_wsgi_app(application)

if __name__ == '__main__':
    main()

We describe the StringListProperty in Page class and use it directly as newpage.keyword=[“item1″,”item2”]
When we want fetching rows that contains “author” string two rows will shown. Becuase only “Suat ATAN’s book” and “Suat ATAN’s life” pages have this string in its StringListPropery

A new version of Python template maker


I developed a script early for dressing pages with demanded template here is newer version:

from BeautifulSoup import BeautifulSoup
#Configuration
root="D:/users/suat.atan/Desktop/yenisehrivan/"
cssroot="/htmlres/css/"
jsroot="/htmlres/js/"

class TemplateMaker():
    def generate(self,NUDEPAGE_NAME):
        NUDEPAGE=open(root+"pages/"+NUDEPAGE_NAME+".html").read()
        index=open(root+"pages/index.html").read()
        soup = BeautifulSoup(index)
        head= soup.findAll("head")
        #header

Dreamweaver-like html template dressing in Aptana with Python


The best way for dressing multiple page with a single template is Dreamweaver HTML template system. This system is ok but not available in Aptana.  For this problem i coded a simple python script that can launchable under Aptana. This script reading head elements of main page for css and javascript’s after this asks the zero-templated(nude) page name and gets content from zero-templated page and combines template and nude page. After that writing templated page to a html file.

For using this script you must download BeatifulPython script and import it.

from BeautifulSoup import BeautifulSoup
root="D:/users/suat.atan/Desktop/myproject/"
index=open(root+"pages/index.html").read()
soup = BeautifulSoup(index)
head= soup.findAll("head")
HEAD= head[0]
html1=""""""
html2="""""" body_name=raw_input("Template page: (withoyut .html expression)-->") body=open(root+"pages/"+body_name+".html").read() html3=""
HTML=html1+str(HEAD)+html2+body+html3
file =open(root+"pages/new_template.html","w")
file.write(HTML)
file.close()
print "Generated"
