The process shown below is and example of using the [] to have the program execute a condition that searches the contents of an array till a match is found. It goes from the top to the bottom to check each and every member of the array to look for a match doing the requested [...]
Railes uses the Model-View-Controller or MVC architecture like many current web frameworks for organizing application programming. MVC in general is an architectural pattern favorably used in software engineering where the application becomes easier and less complex to modify and adjust either the visual appearance of the application or the fundamental business rules without affecting the [...]
More on text editors that are used with RoR and we not discuss VIM or Vi Improved. Vim like Emacs is quite efficient and easy to use with RoR provided it is set-up properly. The nice about Vim is that it has the nifty way of highlighting syntax in ruby making it easy to trace [...]
