Managing Dynamic Forms with Elixir and Phoenix LiveView
The article introduces the concept of managing dynamic forms in the Phoenix LiveView environment for Elixir applications, where users can dynamically add and remove embedded item inputs. It provides a walkthrough of building a sample application, including setting up the project, generating default components with the Phoenix framework, and modifying migrations to use a jsonb field for order items. The author, Benjamin Rosas, shows how to use Ecto v3.10's sort_param and drop_param options to efficiently manage lists of embedded forms for orders and items. These tools allow for adding new items to a list via a sort parameter, and removing items with a drop parameter, making the form reactive and interactive without any JavaScript. The article also includes a cleanup step for existing views to prevent rendering errors.
