Cocoon Gem Example: How to Implement Cocoon Gem in Rails 6?
This tutorial will teach how to use cocoon-shaped gems to create complex and dynamic Rails in Ruby on Rails. For example, suppose you want to create a form for users to enter the names of their friends. You don't know in advance how many friends your users will have. How to add a specific number of fields in the layout?
Rails have no built-in bracket to answer this question. Therefore, to solve this problem, we can use cocoon gems. Cocoon supports JavaScript nested forms so that you can add or remove fields dynamically.
This example shows how to use the cocoon gem to add or delete nested fields asynchronously without creating a new query. We will develop a demo where users can add n friends. Therefore, the friend's name is a sub-attribute of the username.
