Which are the most useful Rails gems to use in Rails? We will have a look at a number of rails gem you can use today. What is Rails? Ruby on Rails is an open-source web framework, which means the code is available to the public for free to examine, use, modify and distribute. So why are organizations choosing to implement it? Ruby on Rails has many advantages over other frameworks. These include security benefits, rapid web development, decoupled components, reduced dependencies and simple maintenance processes. It supports open source libraries that provide all the functionality out-of-the-box for common tasks such as email notifications. Moreover, developers who work with Ruby on Rails are able to take advantage of their expertise in Ruby and software engineering in general.
Top Useful Rails Gems To Use
ActiveRecord is an object-relational mapping (ORM) library that makes it easier for developers to work with database tables and to design and implement applications using Ruby on Rails. It is a layer on top of the database and allows developers to interact with the database using Ruby objects. This makes it possible for developers to use virtually any object as a database column, which increases flexibility and reduces development labor. One of the main reasons why organizations choose to implement ActiveRecord in their projects is because it can be used with any SQL dialect. However, before ActiveRecord can be used in your project, you need to have a working version of Postgres installed which consists of three components: PostgreSQL, pg_config, PostgresSQL itself.
Slim is a template pre-processor that extends the basic functionality of Ruby. The framework makes it easier to use all the features offered by ERB, which is the default templating language for Ruby.

To implement Slim in your project, you need to install the following packages:
