Have you ever struggled with the time and a software project’s dead line, well for sure you should have experienced this kind of situation in many times before, as a developer. In today’s software industry one of most important aspects is the time, along with the talent and skills the ability to complete a certain task within a given period is of time is crucial. This impression leads to rapid application development, which every software company strives to accomplish. So whenever you reach this kind of situation there’s always a solution under the hood and that’s the beauty of software industry. Django Web Framework is one enormous solution that you can look for rapid application development. Python’s simplicity and Django’s flexibility cover up the needs in the context of this matter.
Intro To Python
What Is Django And What’s It Origin?
We can simply describe that Django is a web framework that 100% built using Python. That’s it, it’s really a framework that built for convenience and to reduce the time consuming efforts. Out of the box Django is very conceptive and robust basically the environment, so the developers only have to focus on how they going to implement a certain web application using Django, main considerations that affects a web application. Let’s see how Django is invented (the origin), Django grew organically from real-world applications written by a Web-development team in Lawrence, Kansas, USA. It was born in the fall of 2003, when the Web programmers at the Lawrence Journal-World newspaper, Adrian Holovaty and Simon Willison, began using Python to build applications The World Online team, responsible for the production and maintenance of several local news sites, thrived in a development environment dictated by journalism deadlines. For the sites including LJWorld.com, Lawrence.com, and KUsports.com journalists (and management) demanded that features be added and entire applications be built on an intensely fast schedule, often with only days or hours notice. Thus, Simon and Adrian developed a timesaving Web-development framework out of necessity it was the only way they could build maintainable applications under the extreme deadlines. So if we look at the context of this situation, they invent this framework in order to simplify and to speed the development process of their web applications, that underline concept is the hall way to Django’s success within the industry.
Django’s Current States And Capabilities
Now, several years later, Django is a well-established open source project with tens of thousands of users and contributors spread across the planet. Two of the original World Online developers (the “Benevolent Dictators for Life,” Adrian and Jacob) still provide central guidance for the framework’s growth, but it’s much more of a collaborative team effort. This history is relevant because it helps explain two key things. The first is Django’s “sweet spot.” Because Django was born in a news environment, it offers several features that are particularly well suited for ecommerce site like Amazon.com, Craigslist, and The Washington Post that offer dynamic, database-driven information. Don’t let that turn you off, though, although Django is particularly good for developing those sorts of sites, that doesn’t preclude it from being an effective tool for building any sort of dynamic Web site. (There’s a difference between being particularly effective at something and being ineffective at other things.).Let’s take a look at Django’s most conceptual capabilities.
Based On Model View Controller (MVC) Design Pattern
Although Django is based on MVC design pattern the way it uses the naming for the pattern is bit different
- Models (Model) – abstract the used data by defining classes for them and storing them on a relational database
- Views (View) – take the job of the controllers in MVC and basically define, what the user get to see. Functions (functions that changes according to the model) not classes here.
- Template (Controller) – Define how the users see the view.
Division Of Easiness And Maintainability (Applications And Projects)
Give developer a more modularize way of manipulating the web application’s parts
- Application – this is the point where you store actual functionality. For example a discussion forum would be an application; a weblog would be an application.
- Project – A project is for example your whole web site (entire outcome). Here you store your central configuration and general templates and images.
Applications are a simple way to share common functionality between various projects.
- Python (Django can work above the version 2.5)
- A text editor
This is all what you need to start developing with Django frame work, because it ships with a light weight development server (NOT suitable for production environment) to play around with it.
- Fast CGI (Common Gate way interface) – Common Gateway Interface, a specification for transferring information between a World Wide Web server and a CGI program. A CGI program is any program designed to accept and return data that conforms to the CGI specification. The program could be written in any programming language, including C, Perl, Java, or Visual Basic. Django itself support better processing metrology to up holds a fast CGI surrounding.
- mod_python – is an Apache module that embeds the Python interpreter within the server.
- mod_wsgi – is a simple Apache module implementation which can use to host any Python application which supports the Python WSGI interface.
Supports Most Common Database Engines
Main Features Resides On Developers Perspective
- A good collection of contributed applications
- Administration interface
- Authentication system
- Comments system
- Template language focused in inheritance.
- Simple form processing.
- Lots of fun stuff.
As you can see Django is a more convenient and easy to handle web framework purely built using Python, once you have mastered Django it will simply speed up your application development process and enhance the usability of your application through easy maintainability. Django can be used to develop small-scale corporate web application to expandable ecommerce web applications (this is just a surface markup which means Django can be use to develop further more complex web applications, don’t judge it from the outside view). So Django is currently available as an open source product (under BSD license) all developers, architects and fun makers are invited to use it and experience emphasize power of it.
