The Smoothest Application Development Ride – with Ruby on Rails
Ruby onto Rails has been the topic of debate for years together, yet the capabilities of this cutting-edge technology are not known towards a lot an application developer, within their entirety. What RoR application development provides is an boosted and supremely productive lane towards the rapid industry of network application. Here, we endeavour towards light the distance towards earn this technology accessible and enjoyable towards developer settlements across the globe. So, the next moment you hire RoR developers, you can be ensured that your application shall be up and operating within none moment at all.
Let's activate off with the basics! Ruby is an ideal example of a purist's notion of a pure object-oriented grammar with an easy-to-write and maintain syntax that should be any programmer's dream come-true. And Rails? A framework that is open cause and is perfectly suited towards the industry of web-based, database-driven applications; that's Rails for you. The advantage of this framework is its potential towards grow applications up towards 10x faster than technologies, such as Java! Ruby and Rails leverage each else and the two most meaningful beliefs of lesser ropes of code and convention again form are derived from this amalgamation. As you activate growing RoR network applications, you'll implement that the mount of code required is distance lesser than else technologies. On the else hand, we possess convention again form which cuts the umbilical cord for everybody XML files. You can literally do away with everybody XML form records, as mere programming conventions rob their place.
Okay, already onto the primary course! We shall endeavour and explain the procedure of developing a web-based, database-driven application consuming Ruby onto Rails.
The Installation
Though Rails has always been a breeze when it arrived towards installation and form, there are a lot instruments available today that earn this role even simpler. Based onto your operating environment, you can choose any one of the consecutive options: Instant Rails for Windows, Locomotive for Mac OS X, and Rails LiveCD for Linux.
The Purpose
The application we are aiming towards design is assumed towards appear a list of everybody literature, design and edit prevailing book titles, and categorize literature towards categories according towards their genre, such as crime fiction or sci-fi. Designing the flesh and defining the ground rules for standardizing such as app matters as the UI experience of a user should not disagree from page towards page.
The Process
Here we possess our former brush with the iterative and incremental strategy offered via Rails. Below are the paces required towards grow any application within Rails:
Create a Rails Web Application shell (empty app)
Choose Rails' default database name or specify one yourself
Create the database whether it doesn't exist
Pick and choose your application's features
Create the tables that your app shall consume, whether they don't already exist
Create a code base for the tables
Optimize and modify the code as per your need
Repeat paces 4 -7 till your application industry is complete
Step 1 - Create a Rails Web Application shell (empty app)
Rails provides an endearing feature whereas every Rails app has the equivalent core structure. So, whenever you need towards design a novel app, Rails automatically generates a flesh for this application. This is something that a lot Ruby onto Rails consultants cherish as it affords them the additions bandwidth that they can invest within thinking of innovative features for the app. Your app shall always reside below the Rails Root directory which may be termed differently based onto the environment you use. Open a instruction prompt window and encounter your distance towards this directory. All you possess towards do already is christen your app. Type rails library (remember, our app is for a dynamic database of books?) and voila! Rails devises your app subdirectory and a tree of folders and records – your unfilled Rails app. Rails automatically composes code towards most of these records within the various subdirectories. But there are a few that need a special mention:
app/controllers – consists everybody the controller classes. A controller is a fraction that handles incoming network asks from users.
app/views – consists display templates that are converted towards HTML as soon as filling within data and replaced towards the user's browser.
app/models – consists lessons that theory and wrap the application database contents.
app/helpers – consists helper lessons towards do what their name suggests: assistance the theory, look and controller lessons within their function.
Step two - Choose Rails' default database name or specify one yourself
The database we need towards consume for this application needs towards be specified within a fixed format; its name concatenated with industry, which within this example processes our database shall be branded library_development. We should also endeavour and flee the industry database password blank as it is a convention pursued via Rails. If you ever need towards modify the database name or password, everybody you possess towards do is access and edit \library\config\database.yml.
Step three - Create the database whether it doesn't exist
Now, we design our database. Ensure that the MySQL engine is operating and log into the instruction prompt as a root user. Enter and execute the consecutive commands:
mysql –u root –p
create database library_development
grant everybody onto library_development.* towards ‘ODBC'@'localhost';
exit
Step 4 - Pick and choose your application's features
Here's what earns Rails different from else application industry technologies. Any data we attribute towards rails, it supposes that we shall need towards design, read, update and delete it. In our instance, we too need towards design book titles, edit them, delete them, etc. Therefore as soon as specifying the tables we need for the app, Rails shall automatically produce everybody the plain code. Now, do you appreciate why Rails is up towards 10x faster?
Step 5 - Create the tables that your app shall consume, whether they don't already exist
We are not going towards inhabit onto designing onto tables and defining foreign keys here. All we need towards know is that two tables are required, one for the book titles and another for the categories with a one-to-many relationship.
After designing tables within MySQL, onto the instruction prompt ensure that you are within the library_development directory and execute the consecutive command:
mysql cookbook2_development <db\create.sql
If you replace back towards the instruction prompt, without any letters or blunder, everything went fine.
Step six - Create a code base for the tables
Here, we consume scaffolding – a notion distinctive towards Rails that lets ourselves towards produce a plain application flesh without contravening a sweat. Execute the consecutive instruction onto within your app subdirectory:
ruby script\generate scaffold book book
This generates the theory, look and controller records for the section of our app that shall consume the Titles tables. We do the equivalent for the category part:
ruby script\generate scaffold category category
Step seven - Optimize and modify the code as per your need
We shall consume Mongrel; a popular Rails-friendly network server for hosting our app locally. In the library subdirectory execute the consecutive instruction towards rev up Mongrel:
mongrel_rails start
And, we are done! A few many ropes of code would be required towards patch things up and display proper letters but particularly, our app is up and operating within the blink of an eye!
We are a Ruby on Rails development company that has been leveraging its remarkable advantages for relatively a number of moment, towards design and grow cutting-edge application for our clients. We provide offshore software development services towards companies and organization across the globe and possess achieved a 100% industry rate doing the same. If you wish towards harness the tantalizing power of Ruby onto Rails for the industry of your application, do not hesitate towards get within touch with ourselves and lend RoR developers from our skill pool. You network application shall be up and operating within none moment, and shall occasion par excellence; that's a promise!
