laravel集成baum

安装git https://github.com/etrepat/baum 

运行install后会生成migrate，默认有id, parent_id, lft, rgt, depth, 其他根据自己需要自定

$table->increments("id");
$table->string("title")->comment("栏目名称");
$table->integer("parent_id")->nullable()->index()->comment("父级id"); //生成的
$table->string("keywords")->nullable();
$table->string("description")->nullable();
$table->integer("sort");
$table->integer("is_show")->comment("是否显示");
$table->integer("lft")->nullable()->index(); //生成的
$table->integer("rgt")->nullable()->index(); //生成的
$table->integer("depth")->nullable(); //生成的

模型：

model不继承Model，需要继承Node

<?php

namespace App;

use IlluminateDatabaseEloquentModel;
use Baum;

class Taxon extends  BaumNode
{
    protected $table = "taxons";
    protected $fillable=["title","parent_id","keywords","description", "sort", "is_show", "lft", "rgt", "depth"];
}

自动填充

<?php

namespace AppJobs;

use AppTaxon;
use IlluminateBusQueueable;
use IlluminateFoundationBusDispatchable;

class TaxonFormFields
{
    use Dispatchable, Queueable;

    protected $id;

    protected $fieldList = [
        "title" => "",
        "parent_id" => "",
        "keywords" => "",
        "description" => "",
        "is_show" => "1",
        "sort" => "50",
    ];

    /**
     * Create a new job instance.
     *
     * @return void
     */
    public function __construct($id = null)
    {
        $this->id = $id;
    }

    /**
     * Execute the job.
     *
     * @return void
     */
    public function handle()
    {
        $fields = $this->fieldList;
        if ($this->id) {
            $fields = Taxon::findOrFail($this->id);
        }
        return $fields;
    }
}

自定义request

<?php

namespace AppHttpRequests;

use IlluminateFoundationHttpFormRequest;

class TaxonRequest extends FormRequest
{
  /**
   * Determine if the user is authorized to make this request.
   *
   * @return bool
   */
  public function authorize()
  {
    return true;
  }

  /**
   * Get the validation rules that apply to the request.
   *
   * @return array
   */
  public function rules()
  {
    return [
      "title" => "required"
    ];
  }

  /**
   * Return the fields and values to create a new post from
   */
  public function fillData()
  {
    return [
        "title" => $this->title,
        "parent_id" => $this->parent_id,
        "keywords" => $this->keywords,
        "description" => $this->description,
        "is_show" => $this->is_show,
        "sort" => $this->sort,
        "lang" => "zh-cn",
    ];
  }
}

表单

<div class="form-group">
  <label for="taxon_title" class="col-sm-1 control-label">{{ trans("admin.title") }}</label>
  <div class="col-sm-11">
    <input type="text" class="form-control" id="taxon_title" name="title" value="{{ $title }}">
    <p class="help-block">{{ $errors->first("title") }}</p>
  </div>
</div>
<div class="form-group">
  <label for="taxon_keywords" class="col-sm-1 control-label">{{ trans("admin.keywords") }}</label>
  <div class="col-sm-11">
    <input type="text" class="form-control" id="taxon_keywords" name="keywords" value="{{ $keywords }}">
  </div>
</div>
<div class="form-group">
  <label for="taxon_description" class="col-sm-1 control-label">{{ trans("admin.description") }}</label>
  <div class="col-sm-11">
    <textarea class="form-control" id="taxon_description" name="description">{{ $description }}</textarea>
  </div>
</div>
<div class="form-group">
  <label for="taxon_is_showe" class="col-sm-1 control-label">{{ trans("admin.is_show") }}</label>
  <div class="col-sm-11">
    <input type="radio" id="taxon_is_show_1" name="is_show" value="{{ $is_show }}" @if($is_show == 1) checked="checked" @endif> {{ trans("admin.yes") }}
    <input type="radio" id="taxon_is_show_0" name="is_show" value="{{ $is_show }}" @if($is_show == 0) checked="checked" @endif> {{ trans("admin.no") }}
  </div>
</div>
<div class="form-group">
  <label for="taxon_sort" class="col-sm-1 control-label">{{ trans("admin.sort") }}</label>
  <div class="col-sm-11">
    <input type="text" class="form-control" id="taxon_sort" name="sort" value="{{ $sort }}">
  </div>
</div>
<div class="form-group">
  <div class="col-sm-offset-1 col-sm-11">
    <input type="hidden" name="parent_id" value="{{ $parent_id }}" />
    <input type="submit" class="btn btn-default" value="提交" />
  </div>
</div>

添加分类

/**
   * 创建新表单页面
   *
   * @return Response
   */
  public function create(Request $request)
  {
    $taxon = $this->dispatch(new TaxonFormFields());
    $parent_id = $request->get( "parent_id", "");
    $taxon["parent_id"] = $parent_id;

    return view("admin/taxon/create", $taxon);
  }

  /**
   * 将新创建存储到存储器
   *
   * @param Request $request
   * @return Response
   */
  public function store(TaxonRequest $request)
  {
      $parent = Taxon::find($request->input("parent_id"));
      $taxon = Taxon::create($request->fillData());
      $taxon->makeChildOf($parent);
      
      return redirect("admin/taxons");
  }

修改如果只修改数据，不修改分类结构就按照laravel修改就可以，

/**
   * 显示编辑表单页面
   *
   * @param int $id
   * @return Response
   */
  public function edit($id)
  {
    $taxon = $this->dispatch(new TaxonFormFields($id));
    return view("admin/taxon/edit", $taxon);
  }

  /**
   * 在存储器中更新
   *
   * @param Request $request
   * @param int $id
   * @return Response
   */
  public function update(TaxonRequest $request, $id)
  {
      $taxon = Taxon::findOrFail($id);
      $taxon = $taxon->fill($request->fillData());
      $taxon->save();
      
      return redirect("admin/taxons");
  }

删除

/**
   * 从存储器中移除
   *
   * @param int $id
   * @return Response
   */
  public function destroy($id)
  {
    $taxon = Taxon::findOrFail($id);
    $taxon->delete();
    return response()->json(["error_num" => "0", "link" => "/admin/taxons"]);
  }
