我有这段代码
class MyCustomException extends Exception {
Result result;
}
//do you really need switchMap?
.flatMap(result -> {
if (result.success()) {
return Observable.just(result.getResource());
} else {
return Observable.error(MyCustomException(result));
}
})
//do* operators is meant to call side effect methods without changing the stream
.doOnError(exception -> {
if(exception instanceof MyCustomException) {
Result result = ((MyCustomException) exception).getResult();
onFailure(result);
}
})
.onErrorResumeNext(exception -> {
if(exception instanceof MyCustomException) {
return Observable.empty();
} else {
return Observable.error(exception); //propagate error downstream
}
})
我尝试了<?php
namespace App\Models;
use Reliese\Database\Eloquent\Model as Eloquent;
class B2 extends Eloquent
{
protected $table = 'b2';
protected $primaryKey = 'kip_b1';
public $incrementing = false;
public $timestamps = false;
protected $fillable = [
'entried',
'kip_b1'
];
public function user()
{
return $this->belongsTo(\App\Models\User::class, 'kip_b1', 'username');
}
public function scopeEntried($query){
return $query->where('entried',1);
}
}
php artisan tinker命令提示符返回
BadMethodCallException，带有消息'调用未定义的方法 照亮\数据库\查询\生成器:: entried（）'
