Being a beginner-level ruby on rails developer, imagine one of your code sets has affected the whole app functionality. What would you do? Of course, you have to be prepared to face the consequences!
Thus, if you really want to get rid of mistakes that might have been made in Ruby on Rails development, then you’re at the right place. We will throw some light on them but before that let’s understand the process.
Ruby on Rails (ROR), written in Ruby programming language, is a server-side web application development framework and supports MVC (model-view-controller) architecture.
As this programming language streamlines the whole website development process, it works on the “convention over configuration” principle.
What does Convention over configuration mean?
It is a software development paradigm utilised by many frameworks. Moreover, it helps the developers in making the decisions by decreasing the comings and without compromising on flexibility.
Besides that, it is assumed that expert RoR developers perfectly follow the standardized yet best practice conventions.
Remember, if all the practical principles are under your belt, you never know how magically they would do wonders to your project. But, if you don’t, you are on the verge of a breakdown just because it will disturb your project handling power. Mind you, some projects don’t have the afford to face delays.
In this article, we have compiled all the usual mistakes Ruby on Rails developers make (when the principle conventions are unknown). Let’s plunge into them!
8 Common Mistakes In Ruby On Rails Developers Make
Do you want to know what’s wrong with Ruby on Rails? Then, trust me, there’s nothing like that. Every framework comes with a set of terms and when you don’t do things that way, things go wrong.
So, here, we’re highlighting some of the RoR development mistakes:
- Putting more than the required logic in the model
When we interacted with one of the business owners, he shared an interesting story.
Story: Most developers deploy all their logic in the model layer of MVC architecture. We shouldn’t forget that the model layer is for whole business codes. Yes, logic like email notifications and data conversions must not be added to the model layer if you really want to make your ruby on rails application work out best.
The model layer is suitable for configurations like mutation methods, queries, access wrappers, and relations and validations.
- Stuffing a lot of programming in the view
View layer is specifically for your website appearance. RoR developers use this layer to add HTML or CSS tags. However, some novice developers put database information in this layer which affects the efficiency and load speed of the whole architecture.
- Deployment of too much logic in the controller
Controller, as the name says it all, helps in controlling the management of requested parameters, cookies handling, rendering, or redirecting views of the project. Thus, Ruby on Rails developers should avoid filling up this controller layer as in another case, it will increase the app load time.
- Overlooking your log files
You probably know about the default log files already placed in the database of the framework that can be best used during the production or development of the app. But, you seldom pay heed to them (which is counted as a mistake). Right?
Well, as you must know, many apps are dependent on log monitoring tools. Still, keeping an eye on log files is important for Ruby on Rails project development.
- Lack of automated testing
What Ruby on Rails developers lack in doing is they forget to implement automated testing accurately. However, RoR provides powerful and just efficient automated testing capabilities.
It is a general rule of thumb that one integrated or automated test should be written for each operation in controllers. With this, RoR developers will
- modify or expand the code.
- Update ROR version.
- Verify the real functionality of the application.
- Forget using memorization
Memoization is basically a technique that makes applications faster, and more robust. Also, it speeds up accessors during RoR project development.
The results of different procedures that do hefty work or variables initializing are cached due to this technique. Besides that, it uses ||= operator to configure the cache variable.
- Implement accurate naming conventions in RoR projects
Naming convention is an agreed technique or scheme used to name things. In programming, a set of rules is utilized to choose characters for identifiers which denotes types, functions, and variables.
Some of the basic things to do are:
- Singular model names should be used.
- The plural controller name should be featured and if multiple words are to be added, then use camelcase.
- Avoid using reserved names for the projects. For instance, you can use “Klass” but avoid giving your set of codes the name “Class.”
- Eliminate the complexity by following default routes.
- With plural table names, it is easier to map models or tables automatically.
- Blocking on calls to external services
Ruby on Rails applications that fall under 3rd party providers make it feasible to integrate APIs and may run slowly. Moreover, to avoid blocking on calls, pass some code to the backend job instead of calling services from RoR applications.
If you’re an RoR developer, you would definitely love to avoid these mistakes we have combined under this article. Once these mistakes are known, it is easier to put them off and enhance skills during the development process.
