How do you do relative time in Rails?

How to Do Relative Time in Rails? ⏰🚂

Are you struggling to display relative time in your Rails application? You know, the kind that says "30 seconds ago" or "2 days ago" instead of showing an exact timestamp? Don't worry, you're not alone! Many developers face this dilemma, but luckily, Rails provides an elegant solution to make your life easier. 🙌

The Problem 😫

As a Rails developer, you may encounter situations where you need to display time in a user-friendly and human-readable format. Instead of showing the raw timestamp, you want to show relative time, making it easier for users to understand when an event occurred. In our case, we want to display time like "30 seconds ago," "2 days ago," or "9/1/2008" for dates longer than a month.

The Solution 💡

Rails comes with a handy method called time_ago_in_words that allows you to calculate relative time effortlessly. All you need to do is pass a Time object or a timestamp to this method, and it will return the relative time string for you. Let's see how it works:

<%= time_ago_in_words(@post.created_at) %>

In the example above, we assume you have a @post object with a created_at attribute. By simply calling time_ago_in_words with the created_at value, Rails will do the heavy lifting for you and display something like "5 minutes ago" or "1 day ago" based on the time elapsed since the post was created. 😎

Customization Options 🛠️

Rails provides several options to customize the output based on your requirements. Here are a few commonly used ones:

Limiting Words

By default, time_ago_in_words returns a full sentence, like "5 minutes ago." However, if you want to limit the output to only the relevant part, you can use the :only option. For example:

<%= time_ago_in_words(@post.created_at, only: [:seconds, :minutes, :hours]) %>

This will display a relative time string like "5 minutes" or "2 hours," excluding larger units like days or months.

No Time Ago Text

If you prefer not to include the "ago" part in the relative time string, you can use the :no_time_ago option. For example:

<%= time_ago_in_words(@post.created_at, no_time_ago: true) %>

This will display "5 minutes" instead of "5 minutes ago."

Now, It's Your Turn! 🚀

With the time_ago_in_words method at your disposal, you can now impress your users with beautifully formatted relative time in your Rails application. Say goodbye to boring timestamps and embrace the power of user-friendly time representations! Give it a try and let us know how it goes. 😃
