Uni Ecto Plugin

Debugging complex macro code in Elixir can be frustrating. Keep your plugin macros thin. Have the macro call standard, readable Elixir functions located in a plain module.

Understanding the difference between and constraints is crucial here. Validations are executed by your Elixir code without touching the database, while constraints are enforced at the database level. The unique_constraint/3 leverages the database's unique indexes to provide a safe, race-condition-free mechanism for uniqueness.

Plugins interact with Ecto through three primary integration points: uni ecto plugin

Install the plugin via npm or yarn inside your Uni-app project root: npm install uni-ecto-plugin --save Use code with caution. 1. Initializing the Repository

Trigger events automatically whenever a record is created, updated, or deleted. Debugging complex macro code in Elixir can be frustrating

A robust Ecto plugin needs to be easy to integrate. Ideally, a developer should only need to add a single line of code to their Schema or Repo module to unlock its features. 1. The Schema Extension Boilerplate

defmodule MyApp.User do use Ecto.Schema import Ecto.Changeset Plugins interact with Ecto through three primary integration

: The plugin uses multilayered fractal noise that is color-mapped to create evolving, spooky, or fantasy-inspired visuals. Customizable Presets : It includes approximately 20 adjustable presets

# test_helper.exs Uni.Ecto.Test.start(repo: MyApp.Repo, mode: :no_db)

You might wonder, "Can't I just use Ecto's built-in prepare_changes or multi-statements?"

def uni_broadcast_config do [ topic: fn post -> "posts:#post.id" end, only_if: fn changeset -> # Only broadcast if the status actually changed to "published" Ecto.Changeset.get_change(changeset, :status) == "published" end ] end Use code with caution.
