![]() Web2pyįormerly known as Enterprise Web Framework, Web2py is based on Ruby on Rails, but written in Python (2.5, 2.6 or 2.7 but not 3.*), and designed to prevent common Web security failings such as cross-site scripting. Compared to Django, it’s a bit more flexible. TurboGears lets you create single file applications-simple examples or Web services in minimal mode-then switch to full-stack projects for a more complex website. It’s a sophisticated ORM and is highly regarded. Pylons provides the controller mechanism, Genshi the view through HTML/ XHTML templating and SQLAlchemy looks after the model. It’s built on top of best-of-breed open source components including Pylons, SQLAlchemy, Genshi and Repoze. TG2 was built to try and answer frustrations surrounding TurboGears 1 and Django. Is it perfect? Well, the templating isn’t considered very Pythonic and the ORM is not as good as SQLAlchemy, but it’s got a lot of happy users. Sites built on it include Mozilla, Pinterest and Instagram. Extensibility is one of Django’s strengths. Django is also interesting in that it supports both Python 2.* and 3.* using the single file compatibility library six. It helps that it’s not difficult to install and set up. Like many Python frameworks, Django uses a Model View Controller (MVC) approach and works with all major database engines. Named after the legendary guitarist Django Reinhardt, this is the best known of the frameworks, with over 4,300 sites listed on djangosites. Note that I’ve listed TurboGears2 and Web2py instead of Plone and Zope 2-they’ve been around a bit longer. Let’s look at three frameworks and see how they compare. ![]() Do you really want to write code for working with different types of databases, adding object relational mapping code if necessary? What about generating Web pages, managing sessions and cookies, developing admin interfaces, creating tests and worrying about all the ways hackers can defeat your code? Once you’re up to speed, Web frameworks can save you a lot of time.Ĭlick here to find Python developer jobs. ![]() Unless you have a well-funded and skilled team, it makes more sense to use code that’s already been developed and tested. The point of a Web framework is to save you the effort of writing infrastructure code when developing a non-trivial website. ![]() Web development frameworks in Python are about as common as content management systems in PHP. A visit to PyPi, the official package index, shows that frameworks alone have a whopping 12,514 packages available, with Django, Plone and Zope 2 leading the pack. This will create a project called HelloWorld.One thing Python isn’t short of is packages and Web frameworks. Full stack projects can be quickly created by the following Gearbox command − It is a set of commands, which are useful for management of more complex TG projects. The tg.devtools of TurboGears contains Gearbox. The following is the complete code of our first TurboGears application −įrom tg import expose, TGController, AppConfigĬonfig = AppConfig(minimal = True, root_controller = M圜ontroller())Įnter in browser’s address bar to view ‘Hello World TurboGears’ message. It means that our application is going to be served at port number 8080 of localhost. Server = make_server('', 8080, application) This module has make_server() method which requires port number and application object as arguments.įrom wsgiref.simple_server import make_server As mentioned earlier, we shall use simple_server module in wsgiref package to set up and start it. In order to serve this application, we now need to start the HTTP server. The make_wsgi_app() function here constructs application object. AppConfig class constructor here takes two parameters – minimal attribute set to true and the controller class.Ĭonfig = AppConfig(minimal = True, root_controller = RootController()) Next, set the application’s configuration and declare application object. The TGController class also needs to be imported from tg module. In our first application, index() method is mapped as root of our application. Methods in this class are available for access by decorator from tg module. Simple examples and services can be built quickly with minimal set of dependencies.Īpplication class in a TG application is inherited from TGController class. TurboGears has a minimal mode that makes it possible to create single file applications quickly.
