Laravel:在我的 table 上添加数据时发现 "updated_at" 和 "created_at" 字段
Laravel : An "updated_at" and "created_at" field found when adding data on my table
当我用数据更新我的 table 时,发现了两个额外的字段,我没有添加到我的 table.Let 我显示我的代码详细信息。
迁移tableinquiry_plan详细信息:
public function up()
{
Schema::create('inquiry_plan', function (Blueprint $table) {
$table->increments('id');
$table->unsignedInteger('inquiry_id');
$table->string('title_vacation');
$table->string('email');
$table->string('phone_no', 20)->nullable();
$table->dateTime('start_date')->nullable();
$table->dateTime('end_date')->nullable();
$table->foreign('inquiry_id')->references('id')->on('inquiry_master');
});
}
在我的 planController 上添加了一个函数用于添加 activity:
这是我的控制器函数
public function addactivity(Request $request) {
try {
$validator = Validator::make($request->all(), Inquiryplan::planRules(), Inquiryplan::PlanMessages());
$plandetails = Inquiryplan::SaveOrUpdate($request);
if($plandetails !== false) {
return redirect()->route('plan')->with('success', trans('Plan details added successfully.!!'));
} else {
return back()->with('error', "Unable to save plan details.!!")->withInput();
}
} catch (\Exception $ex) {
dd($ex);
return back()->with('error', "Unable to save plan details.!!")->withInput()->withErrors($validator);
}
}
最后在我的模型中使用 saveOrupdate 函数。
这是我的模型函数
public static function SaveOrUpdate(Request $request) {
try {
$id = $request->get('id', false);
$plandetails = false;
DB::transaction(function () use ($request, &$plandetails, $id) {
$plandetails = $id ? Inquiryplan::findOrFail($id) : new Inquiryplan();
$plandetails->fill($request->all());
try {
$plandetails->save();
} catch (\Exception $ex) {
throw $ex;
}
dd($ex);
});
return $plandetails;
} catch (\Exception $ex) {
throw $ex;
}
}
当我提交表单时 return 错误
"SQLSTATE[42S22]: Column not found: 1054 Unknown column 'updated_at' in 'field list' (SQL: insert into inquiry_plan
(inquiry_id
, title_vacation
, phone_no
, start_date
, end_date
, updated_at
, created_at
) values (0, test title, 9974031835, 2018-02-06, 2018-02-14, 2018-02-06 10:44:45, 2018-02-06 10:44:45))
有什么问题?
在您的模型 Inquiryplan
中,添加此行:
public $timestamps = false;
您可以将此字段添加到迁移文件并重新开始迁移:
$table->timestamps();
所有代码:
public function up()
{
Schema::create('inquiry_plan', function (Blueprint $table) {
$table->increments('id');
$table->unsignedInteger('inquiry_id');
$table->string('title_vacation');
$table->string('email');
$table->string('phone_no', 20)->nullable();
$table->dateTime('start_date')->nullable();
$table->dateTime('end_date')->nullable();
$table->timestamps();
$table->foreign('inquiry_id')->references('id')->on('inquiry_master');
});
}
或只需将 public $timestamps = false;
放入您的模型中。
By default, Eloquent expects created_at
and updated_at
columns to
exist on your tables.
所以你需要在你的迁移文件中添加这个
$table->timestamps();
或者如果您根本不需要时间戳,请将其添加到您的模型文件 public $timestamps = false;
