Thinking Elixir Podcast
Enhancing Testing and Security in Ecto
This chapter explores the use of helper functions and fixtures to optimize testing in multi-tenant applications. It also introduces new Ecto functionality for improved data redaction in logs, enhancing security in schema management.
News includes Phoenix 1.8.0-rc release with DaisyUI styled Tailwind components and magic link authentication, a new design pattern called "scopes", a new privacy-focused feature in Ecto for schema redaction, the Elixir Secure Coding Training project finding a new home at TvLabs, a helpful iex shell tip for multiline commands, and more! We interview Krzysztof Nalepa, the primary creator of LiveDebugger, discussing how this powerful tool helps debug LiveView states and structures, how the project originated, upcoming features, and more.
