Php Laravel save（）方法返回true但不更新记录

我正在使用Elount更新我的表Opportunity

机会模型

<?php namespace App;

use Illuminate\Database\Eloquent\Model;

class Opportunity extends Model {

protected $primaryKey = 'OpportunityID';

protected $table = 'opportunitys';
// relationships
public function csfs()
{
    return $this->hasMany('App\Csf', 'opportunityID');
}

public function benefits()
{
    return $this->hasMany('App\Benefit', 'opportunityID');
}

public function risks()
{
    return $this->hasMany('App\Risk', 'opportunityID');
}

public function projects()
{
    return $this->belongsTo('App\Project', 'projectID');
}

public static function createNewOpportunity($input, $projectID)
{
    $opportunity = new Opportunity;
    $opportunity->value = $input['value'];
    $opportunity->margin = $input['margin'];
    $opportunity->duration = $input['duration'];
    $opportunity->tender_type = $input['tender_type'];
    $opportunity->likelihood_of_success = $input['likelihood_of_success'];
    $opportunity->scope_of_work = $input['scope_of_work'];
    $opportunity->deliverables = $input['deliverables'];
    $opportunity->projectID = $projectID;
    $opportunity->high_level_background = $input['high_level_background'];
    if($opportunity->save())
        {
            Opportunity::leadSalesOppComplete($projectID);
            return true;
        };

}

public static function leadSalesOppComplete($projectID)
{
    $task = Lead::where('projectID', '=', $projectID)->first();
    $task->sales_opp = true;
    return $task->save();
}

我得到了身份证，找到了机会

$something = Opportunity::find($id);

我死了，把这个扔了，我得到了这个

Opportunity {#259 ▼
 #primaryKey: "OpportunityID"
#table: "opportunitys"
#connection: null
#perPage: 15
+incrementing: true
+timestamps: true
#attributes: array:12 [▼
"opportunityID" => 11
"value" => 0
"margin" => 0
"tender_type" => ""
"likelihood_of_success" => 0
"high_level_background" => ""
"scope_of_work" => ""
"deliverables" => ""
"duration" => ""
"projectID" => 6
"created_at" => "2015-03-11 17:45:47"
"updated_at" => "2015-03-11 17:45:47"
 ]
  #original: array:12 [▶]
#relations: []
#hidden: []
#visible: []
#appends: []
#fillable: []
#guarded: array:1 [▶]
#dates: []
#casts: []
#touches: []
#observables: []
#with: []
#morphClass: null
+exists: true
}

这是正确的。然后我用

    $something->margin = $request['margin'];
    $something->duration = $request['duration'];
    $something->tender_type = $request['tender_type'];
    $something->likelihood_of_success = $request['likelihood_of_success'];
    $something->scope_of_work = $request['scope_of_work'];
    $something->deliverables = $request['deliverables'];
    $something->high_level_background = $request['high_level_background'];

现在如果我死了，我会得到

Opportunity {#259 ▼
#primaryKey: "OpportunityID"
#table: "opportunitys"
#connection: null
#perPage: 15
+incrementing: true
+timestamps: true
#attributes: array:12 [▼
"opportunityID" => 11
"value" => "25000"
"margin" => "0"
"tender_type" => "Proposal"
"likelihood_of_success" => "0"
"high_level_background" => ""
"scope_of_work" => ""
"deliverables" => ""
"duration" => ""
"projectID" => 6
"created_at" => "2015-03-11 17:45:47"
"updated_at" => "2015-03-11 17:45:47"
]
#original: array:12 [▼
  "opportunityID" => 11
  "value" => 0
  "margin" => 0
  "tender_type" => ""
  "likelihood_of_success" => 0
  "high_level_background" => ""
  "scope_of_work" => ""
  "deliverables" => ""
  "duration" => ""
  "projectID" => 6
  "created_at" => "2015-03-11 17:45:47"
  "updated_at" => "2015-03-11 17:45:47"
]
#relations: []
#hidden: []
#visible: []
#appends: []
#fillable: []
#guarded: array:1 [▶]
#dates: []
#casts: []
#touches: []
#observables: []
#with: []
#morphClass: null
+exists: true
}

我只更改了显示更改的值

我现在跑步

$something->save();

当我死了并把它扔掉时，它返回真值

但数据库中没有更改任何记录

有什么想法吗

tinker的两个图像

商机模型中的这一行修复了问题

Protected $primaryKey = "opportunityID";

尽管很难理解为什么仍然可以检索数据并创建新记录。

我遇到了一个非常类似的问题，这篇文章让我找到了一个解决方案。我也在重写一个

primaryKey

环境：

• PHP7.1
• 流明5.3（明显有说服力）
• 甲骨文12（使用）

选择
和
插入
操作使用
受保护的$primaryKey='USER_ID'save（）
返回了
true
，但
UPDATE
操作仍不起作用

找到这个帖子后，我换了个案子<代码>受保护的$primaryKey='user_id'，糟糕，这三个操作都可以！我希望我能有一个更确切的解释，为什么这是有效的。当我创建表时，我清楚地使用了upper
用户ID VARCHAR2（50字节）NOT NULL
我对Laravel 5.4和MySQL有同样的问题。我最初的代码是：

$attach = new Attachments ;
$attach->site_id = ($type == 'site' ? $typeId : null) ;
...

通过添加空主id，
save（）
的行为与预期一致

$attach = new Attachments ;
$attach->id = null ;
$attach->site_id = ($type == 'site' ? $typeId : null) ;
...

回答标题中的问题：

$user = \App\User::find(1);
$boolean = $user->save();

这将成为现实。Save始终返回true，除非更新或保存未成功（因为找不到用户id或类似的原因）。如果某个属性已更改，则不会对其进行检查。要查看属性是否已更改，请参见

这里有一点类似于Laravel eloquent Model.php：

    // If the model already exists in the database we can just update our record
    // that is already in this database using the current IDs in this "where"
    // clause to only update this model. Otherwise, we'll just insert them.
    if ($this->exists) {
      $saved = $this->isDirty() ?
         $this->performUpdate($query) : true;
    }


    // ...

    return $saved;

如果模型属性已更改且未保存，
isDirty（）
为真。因此，如果
isDirty（）
为false，模型将不会更新并返回true。
数组$request是什么？其中有任何值吗？如果它是Request的注入实例，请尝试通过调用input（）来获取值，例如$Request->input（'margin'）。如何检查数据库中的记录没有更改？这很棘手。但我认为这个问题与您dd（）save（）有关。我怀疑dd（）只是停止了php脚本的执行。不打断它，直接检查数据库怎么样？非常有趣。当您尝试更新记录时，可能有一些数据库事务正在进行中？另外，您是否可以尝试从
php artisan tinker
更新记录？感觉它与数据库/表的编码有关。
save（）
方法使用Laravel的查询生成器中的
where
创建具有对象属性的查询。因此，最终这并不是真正的Laravel，它只是用您设置的键进行查询。现在您的表编码可以改变情况了，
utf8\u general\u ci
通常被推荐来避免这种问题。这就是解决我的问题！但是我不知道我的代码到底是怎么回事！！！无论如何谢谢你
    // If the model already exists in the database we can just update our record
    // that is already in this database using the current IDs in this "where"
    // clause to only update this model. Otherwise, we'll just insert them.
    if ($this->exists) {
      $saved = $this->isDirty() ?
         $this->performUpdate($query) : true;
    }


    // ...

    return $saved;
