Ruby on Rails continues to be an extremely powerful yet developer-friendly solution for tackling all manner of web projects, and this trend doesn’t appear to be abating anytime soon.\u00a0 Due to Rails’ insistence of “convention over configuration<\/a>“, however, it can often be difficult to precisely determine how you should go about solving a particular problem or what the Ruby on Rails best practices might actually be as the technology rapidly changes from year to year and from version to version.<\/p>\n

While Rails is far too massive a topic to cover everything, in this article we’ve assembled some of the most fundamental Ruby on Rails Examples for 2022 as you embark on your own development journey with Rails and the amazing possibilities with which that entails.<\/p>\n

Ruby on Rails Examples: What You Need to Know<\/h2>\n

1. Jump Start with Scaffolding<\/h3>\n

Scaffolding<\/a> is a great feature of Rails for individuals new to the development, or perhaps those just new to Rails itself. Scaffolding is one of the many generate commands that allows you to automatically create all the framework files you need for a simple object, including the model, controller, database migration file, and basic views.<\/p>\n

For example, if you want to create a simple Book model and all associated components, you might run the following command in the terminal.
\n\"Ruby
\nHere we’re asking rails to generate a scaffold object called Book and then specifying the model fields afterward in the format of field_name:data_type.<\/p>\n

You should immediately see an output with all the generates files and paths.
\n\"Ruby
\nBelieve it or not, you now technically have a working rails application!\u00a0 You can run your rails server ($ rails s)\u00a0 and browse to your localhost to see your functional page.\u00a0 It won’t be pretty, but as is the beauty of Rails, it should just work out of the box with the fields behaving as you expect.<\/p>\n

While scaffolding is a great jumping-off point for developers still learning Rails, much of the code generated by the scaffold command will be wasted or not appropriate for most projects, so be weary of all the files and code created when running this command in your own projects.<\/p>\n

2. Properly Associating Many to Many<\/h3>\n

During development, you may find you need to associate two models through a many-to-many relationship, whereby each instance of a model can be matched with any number of instances of the other model, and vice versa.<\/p>\n

There are essentially two methods by which to create such an association, so we’ll briefly discuss both options and why one method in particular (has_many :through) is the far superior implementation.<\/p>\n
