對不起,我是一個相對Laravel初學者。多對多口才 - 相同型號
我有一個名爲PACS的模型。每臺PACS可以與許多其他PACS相關。從一個到另一個的關係也有一個方向,推或拉。
我PACS模式有一個多對多的關係定義爲
public function pacsRelation() {
return $this->belongsToMany('App\PACS', 'pacs_has_pacs', 'pacsId', 'hasPacsId')->withTimestamps()->withPivot('transferRelation');
}
我的透視表
Schema::create('pacs_has_pacs', function (Blueprint $table) {
$table->increments('id');
$table->timestamps();
$table->integer('pacsId')->unsigned();
$table->integer('hasPacsId')->unsigned();
$table->enum('transferRelation', ['push', 'pull']);
$table->foreign('pacsId')->references('pacsId')->on('pacs');
$table->foreign('hasPacsId')->references('pacsId')->on('pacs');
});
我PACS模型表
Schema::create('pacs', function (Blueprint $table) {
$table->increments('pacsId');
$table->timestamps();
$table->string('email');
$table->string('name');
$table->string('fax')->nullable();
$table->string('edi')->nullable();
$table->string('contact');
});
我有麻煩的我正在執行以下代碼,並且沒有行出現在我的數據透視表中並且沒有錯誤。
public function handle()
{
$this->error("The relationship is defined push or pull by how the receiving party is able to retreive images from the sending party.");
$valid = false;
while (!$valid) {
$receiving = $this->ask('Receiving PACS name');
try {
$pacs = PACS::where('name', '=', $receiving)->firstOrFail();
} catch (ModelNotFoundException $e) {
$this->error('This PACS does not exist');
continue;
}
$valid = true;
}
$this->info($pacs);
$valid = false;
while (!$valid) {
$sending = $this->ask('Sending PACS name');
try {
$sendingPacs = PACS::where('name', '=', $sending)->firstOrFail();
} catch (ModelNotFoundException $e) {
$this->error('This PACS does not exist');
continue;
}
$valid = true;
}
$this->info($sendingPacs);
$relation = $this->choice('Push or Pull relation?', ['push', 'pull']);
$pacs->pacsRelation()->save($sendingPacs, ['transferRelation'=>$relation]);
$this->info('Relationship successfully defined.');
}
有什麼明顯的我失蹤或我走了這個錯誤的方式嗎?
