TurboGears
A python-based web Megaframework
What does it do?
Write web applications faster.
Achieves this by allowing the user to write applications in a high-level interpreted programming
language while conforming to the Model-View-Controller
architecture.
What does it use? Kid CherryPy SQLObject MochiKit
Code Examples
:Model:
# Pretend all the import statements are here.
# Next two lines are generated in every project.hub = PackageHub("newwiki")__connection__ = hub
# SQL equivalent to defining a table Page with the columns# “Pagename” with a length of 30 and “data” with no max length# set. AlternateID=True ensures uniqueness with pagename.class Page(SQLObject): pagename=StringCol(alternateID=True, length=30) data=StringCol()
Code Examples, continued
:Controller:# Pretend there are import statements here, too.wikiwords=re.compile(r"\b([A-Z]\w+[A-Z]+\w+)")#Detects words LikeThis or TurboGears.
class Root(controllers.RootController): @turbogears.expose(html=".templates.page") #Tells TG to use the page template def default(self, pagename): #for root requests along with the return self.index(pagename) #variable pagename @turbogears.expose(html=".templates.edit") #The edit method uses the edit def edit(self, pagename): #template page = Page.byPagename(pagename) #Finds the pagename in the database return dict(pagename=page.pagename, data=page.data, new=False)
