Question

我正在尝试post来自JSON的数据，除非我尝试从Many to Many关系发送数据，否则一切正常。

（我正在使用UUID）

这是我的错误：

SQLSTATE [23000]：完整性约束违规：1048列'idResource'不能为空（SQL：插入CTL_Resource_has_Tags（idResource，idTag）值（，0119a3b2-04da- 11e6-9079-6971fda2300c））

这是我正在尝试post的JSON，其中tags，quickTags和relatedTo是我的Many to Many关系，我只是不知道如何发送它或者我是否使用这个JSON，或者我正在尝试存储数据。

{
  "idResourceType": "0122b128-04da-11e6-9079-6971fda2300c",
  "idCreatorUser": "011d5c46-04da-11e6-9079-6971fda2300c",
  "idModifierUser": "011d5c46-04da-11e6-9079-6971fda2300c",

  "maximumAge": null,
  "fileName": null,
  "extension": null,
  "coachVisibility": "VIS",
  "studentVisibility": "VIS",
  "isHTML": null,
  "studentIndex": "",
  "coachIndex": "",
  "isURL": "on",
  "source": null,
  "path": null,
  "status": "ACT",
  "createTime": "2016-04-18 19:23:18",
  "updateTime": "0000-00-00 00:00:00",
  "isfolder": null,

  "productionKey": "073073097303798",
  "creatorUser": "Tamia Wilderman",
  "creationCountry": "Tanzania",
  "resourceType": "Infografía",
  "tags": [],
  "quickTags": [],
  "relatedTo": []
}

这是我在控制器中的功能，我尝试存储我的数据：

  public function store(Request $request) {


    $resource = new CTL_Resource($request->all());

    $resource->quickTags()->sync($request->quickTags);
    $resource->tags()->sync($request->tags);
    $resource->relatedTo()->sync($request->relatedTo);

  //or $resource->quickTags()->attach($request->quickTags);


    $resource->save();

    return response($resource->load('tags', 'quickTags', 'relatedTo')->makeVisible(
          ['idResource',
            'coachVisibility',
           'thumbnail',
           'studentVisibility',
           'isHTML',
           'studentIndex',
           'coachIndex',
           'isURL',
           'source',
           'path',
           'status',
           'updateTime',
           'isfolder',
           'parentResource',
           'idModifierUser',
           'idResourceType',
           'idCreatorUser',
           'idCreationCountry']
          ), 201);
  }

我的model就是这个：

<?php

namespace Knotion;

use Illuminate\Database\Eloquent\Model;

  protected $table = "CTL_Resource";
  protected $primaryKey = "idResource";

  public $incrementing = false;

尝试在同步属性之前保存模型，这样：

$resource = new CTL_Resource($request->all());

$resource->save();

$resource->quickTags()->sync($request->quickTags);
$resource->tags()->sync($request->tags);
$resource->relatedTo()->sync($request->relatedTo);
