Ruby on Rails includes tools that make common development tasks easier "out-of-the-box", such as scaffolding that can automatically construct some of the models and views needed for a basic website. Together with Ruby on Rails, these tools provide a basic development environment. Ruby on Rails is most commonly not connected to the Internet directly, but through some front-end web server.
The latter is the facility for RESTful web services. Ruby on Rails is separated into various packages, namely ActiveRecord an object-relational mapping system for database access , Active Resource provides web services , Action Pack, Active Support and Action Mailer.
Prior to version 2. Apart from standard packages, developers can make plugins to extend existing packages. Earlier Rails supported plugins within their own custom framework; version 3.
Ruby on Rails is often installed using RubyGems , a package manager  which is included with current versions of Ruby. Many free Unix-like systems also support installation of Ruby on Rails and its dependencies through their native package management system. For example, if there is a class Sale in the model, the corresponding table in the database is called sales by default. It is only if one deviates from this convention, such as calling the table "products sold", that the developer needs to write code regarding these names.
Generally, Ruby on Rails conventions lead to less code and less repetition. For example, using the ActiveRecord module of Rails, the developer does not need to specify database column names in class definitions.
Instead, Ruby on Rails can retrieve this information from the database based on the class name. The episode gave rise to a polite protest in the Ruby on Rails community. I only grant promotional use [of the Rails logo] for products I'm directly involved with.
Such as books that I've been part of the development process for or conferences where I have a say in the execution. I would most definitely seek to enforce all the trademarks of Rails. Rails running on Matz's Ruby Interpreter the de facto reference interpreter for Ruby had been criticized for issues with scalability. In , Gartner Research noted that despite criticisms and comparisons to Java, many high-profile consumer web firms are using Ruby on Rails to build scalable web applications.
In March , security researcher Egor Homakov discovered a "mass assignment" vulnerability that allowed certain Rails applications to be remotely exploited, and demonstrated it by non-maliciously hacking GitHub after his earlier attempts at responsible disclosure were dismissed.
On September 24, , a session cookie persistence security flaw was reported in Ruby on Rails. In a default configuration, the entire session hash is stored within a session cookie known as CookieStore , allowing any authenticated session possessing the session cookie to log in as the target user at any time in the future.
As a workaround, administrators are advised to configure cookies to be stored on the server using mechanisms such as ActiveRecordStore. Researchers Daniel Jackson and Joseph Near developed a data debugger they called "Space" that can analyze the data access of a Rails program and determine if the program properly adheres to rules regarding access restrictions. On April 15, , Near reported that an analysis of 50 popular Web applications using Space uncovered 23 previously unknown security flaws.
