Why can't Yii2 inject dependency and throw NotInstantiableException?

Question

Yii

Exception 'yii\di\NotInstantiableException' with message 'Can't instantiate core\lib\goodsProvider\GoodsBuffer.'

There is a GoodsBuffer class - it itself without a constructor:


It must be thrown as a dependency into the JackFinder class, GoodsBuffer goes as the 2nd parameter:


I get an exception: Exception 'yii\di\NotInstantiableException' with message 'Can not instantiate core\lib\goodsProvider\GoodsBuffer .'

Exception 'yii\di\NotInstantiableException' with message 'Can not instantiate core\lib\goodsProvider\GoodsBuffer.'

1. Namespace is specified correctly in accordance with the autoloader standard:


2. The autoloader must also see the core directory: it even contains FinderInterface, which implements JackFinder.

What could be the problem?

Answer 1

Hang up. I guessed to call the class without DI, through new:

public function __construct()
    {
        $this->buffer = new GoodsBuffer();
    }

Got an error from PHP. I forgot to change the version in the console:

Exception 'ParseError' with message 'syntax error, unexpected 'array' (T_ARRAY), expecting function (T_FUNCTION) or const (T_CONST)'

It was necessary to think of calling through new right away - it would save an hour of time.

Answer 2

Try like this

SELECT id,SUM(кол-во)
GROUP BY id
HAVING SUM(кол-во) > someValue

Answer 3

SELECT *
FROM table1
WHERE id IN ( select id 
from table1 GROUP BY id
HAVING SUM(кол-во)) >= 2
