Differences Between Includes and Joins in Ruby on Rails

Too Long; Didn't Read

Many of us know about includes, joins but sometimes we confuse about their usage. As I was experimenting with code refactoring in one of my projects, there I have tried these things. As we know includes and join are used when we are performing operations on associated tables. Both are used for the same purpose. When we want to fetch data along with an associated table then includes must be used.Joins: Uses lazy loading. Includes: Uses eager loading, When. We can use joins when we. want to consider the data as a condition from the joined table.
