Top Ruby on Rails programmers Best Practices

Ruby on Rails (RoR) is an open-source framework with an intuitive design and syntax requirements that simplifies the web development process. Ruby on Rails is a language with a stronger inclination toward convention rather than arbitrariness. Hence, Ruby on Rails programmers needs to acquaint themselves with a number of RoR development best practices. This is in order to master how to write modular and concise codes for web development projects.

Although it has been emphasized that Ruby on Rails programmers are to be mindful of syntax, there are a number of other principles that can help simplify the entirety of the web development process. The following is a rundown of 5 principles that serve as a guide.

1. Minimizing the Placement of Logic in the Controller

Since Ruby is a language based on MVC architecture, it's a good practice to minimize the collection of logic in the controller. Renowned Ruby on Rails experts are always cautious, ensuring they don't become accustomed to placing view logic, domain logic, etc., into the controller.

That's because while it's easier to do so, it ultimately impels the controller object to infringe the single responsibility principle, and this, in turn, creates complications. These complications make it difficult to effect changes in the app eventually.

Not every logic shouldn't be housed in the controller. Even though these may still partly breach the single responsibility principle, they do allow Ruby on Rails programmers to manage the controller more efficiently.

These include Session and Cookie Management, which encompasses every cookie processing protocol, including authentication and authorization. Model Selection, which entails the use of a single find method that sets an instance variable to deliver subsequent responses, to find appropriate model objects based on request parameters. The Request Parameter Management used to identify the request parameters and the corresponding model methods. Rendering and Redirecting, which is responsible for displaying results or redirecting accordingly.

2. Prioritizing the Review of Log Files

Many Ruby on Rail programmers turns to the default log files of the development and production only when an issue arises. When you look to hire Ruby on Rails programmer, it's imperative to look for programmers who're inclined to monitor the log files of the development and testing phases.

By making proactive use of log files, Ruby on Rails programmers can ensure that the SQL, which is automatically rendered by the platform for the definition of associations in the model's, is efficient. In doing so, Ruby on Rails experts can easily identify errors in their code before the application is deployed.

This helps to eliminate errors which may otherwise slip past the tests into the production, because the size of the dataset available in the development and testing phase may be too insignificant to show any errors until the dataset begins to expand during the production to show lapses that give rise to performance problems in the app.

3. Implementing Tests Efficiently

Despite the fact that testing a development before production sounds ideal, some Ruby on Rails programmers still finds reasons to side-step this crucial stage of the development. There are a handful of automated tests that have been built into the platform, that is well worth the effort to put to good use.

In addition, there are a host of gems like RSpec and Cucumber that provide powerful test mechanisms for RoR developments. Seasoned Ruby on Rails experts usually develops highly effective TDD and BDD style tests by themselves. When vying to hire Ruby on Rails programmer, you need to find out which test measures are deemed appropriate by the programmer for your development.

Deft Ruby on Rails programmers uses at least one sophisticated integration test for every action in the controller. Such tests are expedient not just for the initial development, but for subsequent extensions and upgrades of the app.

They provide evidence of error-free operations, testing the basic functionalities of the app for use during both the implementation of the production and post-production phases of the app. The tests also provide a comprehensive inventory of the function of the app to future developers who might be implementing feature enhancements or extensions for the app.

4. Using Symbols in Place of Strings in Hashes

Symbols are better than strings most times in the code because they represent specific data-types that can be used to denote variables immutably. In addition, they take up only a single spot in the memory, making for space-efficiency.

So, when conciseness is a major requirement in the project, symbols are more appropriate for use in saving the name of a variable. Also, for variables whose values must remain immutable, symbols are most-suitable characters for the creation of the variable's name. Besides, seasoned Ruby on Rails experts reckon that it's much easier to write condensed Ruby hashes that have symbols as keys than Ruby hashes with strings.

5. Using Gems Cautiously

As in any widely used programming platform, there is an ever-expanding pool of gems for just about any conceivable functionality in Ruby on Rails. Although these gems can help fast-track app developments, an over-reliance on them is not advised.

Every gem operates within an ecosystem of gems, so the addition of one gem necessitates the inclusion of many others. A disproportionate amount of gems in an application's Gemfile ultimately imposes a drag on the app's process, leading to performance issues and slower test processions. This can also necessitate more complex server memory configurations, leading to additional operational cost.

When you look to hire Ruby on Rails programmers, it's important to access the programmer's inclination towards deploying gems. It's advisable for Ruby on Rails programmers to deploy custom made functionalities in place of gems for as much as possible.

Conclusion

Ruby on Rails is a platform which allows Ruby on Rails experts to master various aspects of an app development, including the naming, coding, model selection, etc. through the application of a finite set of guiding principles. The application of the aforementioned practices, even when you're looking to hire Ruby on Rails programmer for your development, can help eliminate common coding errors and design flaws, and enhance extensibility in your development.
