Question

我正在尝试更新＆＃34; contrato＆＃34;来自用户，但我收到此错误：

SQLSTATE[42S22]: Column not found: 1054 Unknown column ' contrato' in 'where clause' (SQL: select count(*) as aggregate from `contratos` where ` contrato` = 3261026)

我试图解决但我无法看到我的错误。

在控制器中，我正在进行验证，我可以修改＆＃34; contrato＆＃34;忽略用户，这样我就不会得到错误＆＃34;这个contrato存在。＆＃34;

控制器代码

public function update(Request $request, $id)
{
    $user = Auth::user();
    $contrato = Contrato::find($id);

    $request->validate([
            'contrato' => [
                'required','numeric','unique:contratos, contrato, '.$user->id' ','digits:7',
                new ValidateContrato,
            ],
        ]
    );

    $contrato->update([
        'contrato'  => $request->contrato,
    ]);

    session()->flash('message','¡Su contrato fue editado satisfactoriamente!');

    return redirect()->route('contratos.index');
}

用户模型

class User extends Authenticatable
{
    use Notifiable;

    public function contrato(){
        return $this->hasMany(Contrato::class);
    }

    public function card(){
        return $this->hasMany(Card::class);
    }

    public function pago(){
        return $this->hasMany(Pago::class);
    }

    /**
     * The attributes that are mass assignable.
     *
     * @var array
     */
    protected $fillable = [
        'name', 'lastname', 'alias', 'cedula', 'email', 'email2', 'password', 'cellphone', 'homephone', 'faxphone', 'officephone', 'born_date', 'terms_accepted', 'invoice_by_mail',
    ];

    /**
     * The attributes that should be hidden for arrays.
     *
     * @var array
     */
    protected $hidden = [
        'password', 'remember_token',
    ];
}

contrato模型

class Contrato extends Model
{
    public function user(){
        return $this->belongsTo(User::class);
    }
    /**
     * The attributes that are mass assignable.
     *
     * @var array
     */
    protected $fillable = [
        'id', 'contrato', 'user_id', 'emition_date', 'payment_reference',
    ];
}

Answer 1

你的错误在于这一行：

'required','numeric','unique:contratos, contrato, '.$user->id' ','digits:7',

删除contrato之前的空格。该行应如下所示：

'required','numeric','unique:contratos,contrato,'.$user->id' ','digits:7',

Answer 2

请更新您的验证规则，如：

$request->validate([
        'contrato' => [
            'required,numeric,unique:contratos,contrato,'.$user->id.',digits:7',
            new ValidateContrato,
        ],
