Do you ever find yourself needing to grab specific data from your database without the need for instantiating entire Active Record objects? Maybe you just new one or another attribute and that’s it. Well, have no fear, because the pluck method is here to save the day!
Using pluck, you can easily retrieve specific columns from your database without the overhead of creating full Active Record objects. This can be a huge time-saver and optimization for your application.
Here’s an example of how to use pluck with a model called Destination that has the these fields: id, name and description, all of them of type String. Check it out:
1
2
3
4
5
# This will retrieve an array of all the destination names in the table
names = Destination.pluck(:name)
# This will retrieve an array of arrays, where each inner array contains the `id`, `name`, and `description` of a destination
destination_attributes = Destination.pluck(:id, :name, :description)
So the next time you find yourself needing to quickly retrieve specific data from your database, give pluck a try!
Happy coding :)
