A Brief

Rails is opinionated software.  It makes the notion that there is a better method to do things, and it is intended to encourage that technique and in certain cases to discourage options.  If you understand ‘The Rails Way’, you will perhaps determine a wonderful upsurge in productivity.  If you continue to bring old behaviors from other languages to your Rails project development and strive to utilize designs you have learned somewhere else, you may get fewer contented experiences.

The Rails philosophy comprises two main guiding philosophies:

  • Don’t Repeat Yourself (DRY):  DRY is a philosophy of software development that describes that ‘Every portion of information must have an unambiguous, single, and authoritative depiction within a scheme.’  By not writing similar information again, the code is more extensible, more sustainable, and less buggy.
  • Convention over Configuration (CoC):  Rails has estimations about the greatest way to do several things in any web application, and defaults to the set of conventions, rather than necessitating that you specify details through infinite configuration files.
