The Stand Out feature of Pylons from other Web Frameworks
Pylons framework is an open source web application written in python. Pylons Framework is strongly influenced by Ruby on Rails: with two of its main components, Webhelpers and Routes. There is a page on web framework by the Python wiki that lists over 25 different frameworks. It is a time consuming to try all the frameworks before concluding which among the list meets your needs. Below are some features you will find interesting to know:
Programming is the process is taking an algorithm encoding it into a notation, a programming language so that the computer can easily execute it. In its simplest form, programming could also mean making mistakes. In web applications, making mistakes is inevitable. Web Frameworks, in general, do not have debuggers that allows one to view the variables and the piece of code originating the error. It is quite a stressful assignment to search for the cause of error while working. At times, most programmer’s intentionally makeup exception statements to make their web application stop at a line, to investigate errors. Interestingly, Pylons offer an online debugger. If your web application by any chance throws an exception, you will get a backtrack on the web page. The debugger works with AJAX (Client-side Script) requests, thereby printing the debug URL on the console.
Exploring the World: Paster shell
As mentioned above Pylons is an open-source web application framework written in Python. It runs using different instances of python modules. The application work environment is opaque. The paster shell is a Python shell and you can run it in your work environment. Pylons offer a variety of utility functions and global variables. For a personal understanding on navigating through the application, it is quite necessary to explore the Webhelpers utilities and surf through the available global variables. Fortunately, if things turn as expected to your taste, you can copy them into your application without thinking twice.
Simplifying the development cycle: -reload
Running an application has a full command, which is paster serve –reload development.ini. The Paste(r) web server monitors your Python files, thanks to the reload option. If a sudden alteration is carried out on the code and it is saved, the paster is fast to detect the change. The application will then run as the new code is loaded. The simplest development cycle that could be is simply just saving you file and reloading your web page.
WSGI – ready for production use
Unlike other web frameworks that may have a web server built in, Pylons do not depend on a certain web server for operation. There is an option to switch between web server based on your taste and preference as long as your choice of a web server is conversant with WSGI. The Web Server Gateway Interface is a requirement for the simple and general interface between web frameworks and web servers for Python Programming language.
Pylons stand as a template for your web application project. Pylons create and modify files where your database models, Your Controller code and your HTML templates are located. Upgrades will be the reason why you will consider changing the template. In other to assist in your consideration, Pylons illustrates the difference and comparisons between the new template and the current template you are operating. The choice to upgrade the template is strictly a decision on your choice and conviction with the new template.
