time_ago_in_words for created_at model in rails
The time_ago_in_words
method in Ruby on Rails is a helpful tool for displaying a human-readable representation of a time interval. It is commonly used to show how long ago a specific timestamp occurred.
To use the time_ago_in_words
method in a Rails application, you need to follow these steps:
Step 1: Ensure the gem is installed
Make sure that the rails
gem is included in your Gemfile. If it's not already there, add the following line:
gem 'rails'
Then, run bundle install
to install the gem.
Step 2: Include the ActionView module
To use the time_ago_in_words
method, you need to include the ActionView::Helpers::DateHelper
module in your view or controller. You can do this by adding the following line:
include ActionView::Helpers::DateHelper
Step 3: Use the time_ago_in_words
method
Once you have included the ActionView::Helpers::DateHelper
module, you can call the time_ago_in_words
method to display a human-readable time interval. Pass in the timestamp you want to convert as an argument to the method, like this:
time_ago_in_words(created_at)
The created_at
argument should be a timestamp, such as the created_at
attribute of a model object.
Step 4: Display the result
To display the result of the time_ago_in_words
method, you can simply output it in your view or assign it to a variable. For example, you can do something like:
<%= time_ago_in_words(created_at) %>
This will output a human-readable representation of the time interval since the created_at
timestamp.
That's it! By following these steps, you can use the time_ago_in_words
method in your Rails application to display how long ago a specific timestamp occurred.
