We are in an interconnected world, where people across the planet can use the projects that we develop, and having the opportunity to offer them with additional international languages make them a lot better. We can obviously use locale for doing the translations of static strings like labels, or placeholder descriptions that appear across our applications, so we should also have something that can give us a way to translate the dynamic content. There is a really great Ruby gem that makes the translation of model attributes a lot easier. This gem is called Globalize and is very easy to use.
One of the things that may prevent us from changing or even just thinking of changing our working environments is the necessity to do all the installations and the configurations that we once set up that are needed for software development. Fortunately, there is a cure for this pain. Laptop is a script that prepares your working macOS machine for web and mobile development.
One of the main reasons why we as developers love programming in Ruby is because of the freedom that it gives to us. Having the autonomy to do something is one of the core pillars of motivation. In this article, we will briefly see how you can write a method that you can then call for each of your string objects, prepending an “a” or “an” before words.

It is very difficult to think about an application that does not have any string data type. Names, emails, object attributes, etc. are very common. Knowing their wide usages, it is obvious that we should at least learn the best practices about them. I recently learned about the difference between the efficiency of two similar string functions, which was a bit surprising and that made me write this article. Although both methods do the concatenation of strings, there is a big difference in their performance.

Fortunately, as with many other type of functionalities that you can easily get out of the box without writing too much code in Rails projects, there is also a gem that is specific for this purpose. Ransack is a Ruby gem that enables the creation of both simple and advanced search forms for Ruby on Rails projects.

It is no doubt that one of the activities that takes most of the time of software developers is debugging. We as programmers can make many mistakes, which may lead to many bugs that need to be fixed. One of the best ways to fix these bugs, understand the flow of an application, or implement new features is through debugging. ByeBug is a great Ruby gem that helps us fix bugs and debug projects by going through each line. It is similar to pry, with additional functionalities.

It is no doubt that there are certain pages that you do not need to have them viewed by all the visitors of your application. You can also have users of different roles that may not be allowed to access certain parts of your applications. There is a really good Ruby gem called cancan that excels at this. It makes the authorization of your app resources pretty straight-forward, so you do not have to duplicate permission checking code across controllers and views.
Rails controllers have callbacks that can be useful when we want to execute a particular piece of code before or after other methods have been invoked. However, there is no Rails built-in after_response_sent callback that could be used to invoke a method after we have rendered the response to the user, either via an HTML or JSON response.

Retryable is another handy gem that lets you repeat a code block after an exception has happened. It has a really easy syntax, and comes with many customizations, that make it a great tool to use, especially when you have to work with web services.
