Supporting Individual, Organization, & Organizational Unit relational hierarchies. - [Quick Start](#quick-start) ``` composer require poing/ylem php artisan ylem:seed ``` Like the primordial substance from which all matter is formed, this is *intended* as the **core** application fabric for business and consumer interaction. Directed Acyclic Graph (DAG) ---------------------------- [](#directed-acyclic-graph-dag) Topological ordering and [directed acyclic graph](https://en.wikipedia.org/wiki/Directed_acyclic_graph) functions are provided for Laravel Eloquent models by the [`gazsp/baum`](https://packagist.org/packages/gazsp/baum) package. *`baum/baum` is no longer maintained.* While some *key* functions will be covered in this document, see the [complete documentation](https://github.com/gazsp/baum) for additional functions. The use of the Dijkstras algorithm, to determine the shortest path, is **not** a *necessary* consideration of this project. Dijkstras algorithm functionally is **not** provided by the `gazsp/baum` package *anyway*. [Package discovery](https://laravel.com/docs/5.7/packages#package-discovery) for `gazsp/baum` is handled by the extra section of **this** packages `composer.json` file. *Just to make it easier to use.* Recursive Functions ------------------- [](#recursive-functions) Recursive functions are **important** for *cyclining* through **all** elements in the tree. This is because the `depth` of nodes and all decendants **will** be different. *This is the **advantage** that DAG provides, you're not locked into a strict level of hierarchies.* ``` . ├── alpha │   └── bravo │   └── charlie └── one └── two └── three └── four └── five └── six └── seven └── eight └── nine └── ten └── eleven └── twelve ``` ### Blade [](#blade) Below is an *example* of *recursive* iteration using the Blade templating engine provided with Laravel. *Recursive iteration can be acheived with `PHP` and other languages **too**.* Generating an unordered list output, *similar* to the tree *shown above*. ``` function getBlade() // Function or Route { $roots = \App\DirectedAcyclicGraph::roots()->get(); return view('roots', compact('roots')); } ``` ``` @foreach ($roots as $item) {{ $item->someValue }} @include('nodes', array('items' => $item->getImmediateDescendants())) @endforeach ``` ``` @foreach ($items as $item) {{ $item->someValue }} @include('nodes', array('items' => $item->getImmediateDescendants())) @endforeach ``` Quick Start ----------- [](#quick-start) 1. Create a Laravel Project ``` laravel new project_name -or- composer create-project --prefer-dist laravel/laravel project_name ``` 2. `cd project_name` 3. `composer require poing/ylem` 4. Publish the Laravel package ``` php artisan vendor:publish --provider Ylem\\Providers\\YlemServiceProvider ``` 5. `php artisan migrate` 6. Seed the demo table *This could take a while, builds `10` root nodes with random nested itmes.* ``` php artisan db:seed --class=Ylem\\Database\\Seeds\\StubSeeder ``` 7. Open `/ylem` in a browser. ### Stub Model and Data [](#stub-model-and-data) You will see the random data *associated* to `Ylem\Models\Stub`. This is simply a test table, once *seeded*, it can be used to *examine* the relationships. Faker is used to create: Company Name, JOB TITLE, and People Name. ``` $faker->company └── strtoupper($faker->jobTitle) └── $faker->name ``` ### php artisan tinker [](#php-artisan-tinker) Here are some `tinker` commands to check out: ``` $node = Ylem\Models\Stub::find(50); $node->isRoot(); // Checks if root node $node->getRoot(); // Gets the root node $node->parent()->get(); // Gets parent node, if not root $node->siblings()->get(); // Gets siblings, sharing the same parent $node->children()->get(); // Gets any children for this node ``` ### Health Score 25 — LowBetter than 37% of packages Maintenance20 Infrequent updates — may be unmaintained Popularity10 Limited adoption so far Community8 Small or concentrated contributor base Maturity53 Maturing project, gaining track record Bus Factor1 Top contributor holds 87.9% of commits — single point of failure How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
