Ruby on
Rails has been around for quite some time and has generated quite a buzz
because of its adeptness at rapid development of web applications. Many a RoR development company has benefited from its inherent advantages. Experts and
experienced Ruby on Rails consultants will vouch for the fact that as simple as
RoR development is, it is not without its traps; traps that are sprung by many
an experienced developer! Here we try to outline 5 such common errors that have
perennially plagued Ruby on Rails web application development.
- If you do not define schema constraints, your data model that acts as the heart of your application will slowly degrade leading to data corruption owing to bugs in your code. This will infallibly lead to a stage where no data will populate any of the fields in your application.
- Writing MVC-oriented code is another error that sets you back. The beauty of RoR is that you can adhere to an object-oriented model to simplify and streamline code. You don’t need to add model and controllers in expected locations similar to an MVC structure.
- Not using content_tag is a big error that can lead to gaping security holes in your XSS. Creating helper methods and defining tags will reduce ugly string concatenation and interpolation.
- Overloading memory is a classic glitch that pulls down the response time of ecommerce sites. Imagine iterating again and again through a large stack of data every time a user access the site, to sift and find the right record. Use find_each that pulls only a 1000 records at one point in time, drastically reducing dynamic memory requirements.
- Not performing a peer code review can lead to on-dimensional errors. Using GitHub to generate a pull request and letting your team review your code, will make it more efficient and of higher quality.
