Source: https://masteringphoenixforms.com/Forms in Phoenix don’t have to be complex. Phoenix, Ecto, and LiveView allow you to create complex, interactive forms with incredible speed — but to do so, you’ll need to understand a series of interconnected concepts.
To truly understand what you are doing, it’s important to master changesets, schemas and validations, and to_form/1, nested parameters, associations, embeds, CoreComponents, and much more.
Mastering Phoenix Forms is a detailed practical guide that systematically and consistently explains all aspects of working with forms. The course is presented in a text format and includes 60 lessons with a clear structure.
During the course, you will create two full-fledged applications in Phoenix: from a simple form in “deadview” with basic fields to a complex LiveView form with dynamic nested associations and advanced logic.
The material is presented step by step — from basic principles to more complex topics. Each new concept is introduced at the optimal moment to ensure maximum understanding and a solid foundation.
By the end of the course, forms in Phoenix will no longer seem confusing. Having mastered the overall architectural picture of how Phoenix, Ecto, and LiveView interact, you will be able to quickly create complex, dynamic, and maintainable solutions — and you’ll have a new appreciation for the power of LiveView as a development stack
