getRewriteByProductStore does not return product URL rewrite

[daniel-ifrim]

Preconditions (*)

1. Magento 2.2.7 but I think it's on all version Magento 2.3-develop branch too
2. MySQL 5.7.26

Steps to reproduce (*)

1. Not much to test unless you make a code construct like this:

/* @var \Magento\Catalog\Model\ResourceModel\Url $this->catalogUrl */
$this->catalogUrl->getRewriteByProductStore([$productId => $storeId])

Expected result (*)

1. It should return an array with product slug like this:

[4256] => Array
        (
            [store_id] => 9999
            [visibility] => 4
            [url_rewrite] => lorem-ipsum.html
        )

Actual result (*)

1. It returns product category URL in some cases:

[4256] => Array
        (
            [store_id] => 9999
            [visibility] => 4
            [url_rewrite] => test-category/lorem-ipsum.html
        )

It happens because the SQL query from
\Magento\Catalog\Model\ResourceModel\Url::getRewriteByProductStore
doesn't look good.

This is wrong:

)->joinLeft(
    ['r' => $this->getTable('catalog_url_rewrite_product_category')],
    'u.url_rewrite_id = r.url_rewrite_id AND r.category_id is NULL',
    []
);

To get rows from table url_rewrite not in left joined table catalog_url_rewrite_product_category
we should remove AND r.category_id is NULL from left join and add it in where as:

AND r.url_rewrite_id IS NULL

where r is the alias of table url_rewrite.

Leaving AND r.category_id is NULL' in join condition will create a result with more than one row. I get all rows for that specific product including rows with product category request_path.

Further down in function getRewriteByProductStore
it adds to return variable the last row for a product:

$rowSet = $connection->fetchAll($select, $bind);
foreach ($rowSet as $row) {
    $result[$row['product_id']] = [
        'store_id' => $row['store_id'],
        'visibility' => $row['visibility'],
        'url_rewrite' => $row['request_path'],
    ];
}

In my case the last row is product category request_path and is not product request_path.
The product request_path is in the first row from the result set ($rowSet).

Query done in getRewriteByProductStore

SELECT `i`.`product_id`, 
       `i`.`store_id`, 
       `i`.`visibility`, 
       `u`.`request_path` 
FROM   `catalog_category_product_index_store22` AS `i` 
       LEFT JOIN `url_rewrite` AS `u` 
              ON i.product_id = u.entity_id 
                 AND i.store_id = u.store_id 
                 AND u.entity_type = "product" 
       LEFT JOIN `catalog_url_rewrite_product_category` AS `r` 
              ON u.url_rewrite_id = r.url_rewrite_id 
                 AND r.category_id IS NULL 
WHERE  (( i.product_id = 4256 
          AND i.store_id = 22 
          AND i.category_id = 2 ));

It returns 3 rows.

Query modied:

SELECT `i`.`product_id`, 
       `i`.`store_id`, 
       `i`.`visibility`, 
       `u`.`request_path` 
FROM   `catalog_category_product_index_store22` AS `i` 
       LEFT JOIN `url_rewrite` AS `u` 
              ON i.product_id = u.entity_id 
                 AND i.store_id = u.store_id 
                 AND u.entity_type = "product" 
       LEFT JOIN `catalog_url_rewrite_product_category` AS `r` 
              ON u.url_rewrite_id = r.url_rewrite_id
WHERE  (( i.product_id = 4256 
          AND i.store_id = 22 
          AND i.category_id = 2 )
          AND r.url_rewrite_id IS NULL);

It returns 1 row with product request_path.

UPDATE
The SQL query should include u.redirect_type=0 also because otherwise it can take row with redirect_type=301 (permanent redirects).

This code

            $select = $connection->select()->from(
                ['i' => $this->tableMaintainer->getMainTable($storeId)],
                ['product_id', 'store_id', 'visibility']
            )->joinLeft(
                ['u' => $this->getMainTable()],
                'i.product_id = u.entity_id AND i.store_id = u.store_id'
                . ' AND u.entity_type = "' . ProductUrlRewriteGenerator::ENTITY_TYPE . '"',
                ['request_path']
            )->joinLeft(
                ['r' => $this->getTable('catalog_url_rewrite_product_category')],
                'u.url_rewrite_id = r.url_rewrite_id AND r.category_id is NULL',
                []
            );

            $bind = [];
            foreach ($productIds as $productId) {
                $catId = $this->_storeManager->getStore($storeId)->getRootCategoryId();
                $productBind = 'product_id' . $productId;
                $storeBind = 'store_id' . $storeId;
                $catBind = 'category_id' . $catId;
                $bindArray = [
                    'i.product_id = :' . $productBind,
                    'i.store_id = :' . $storeBind,
                    'i.category_id = :' . $catBind
                ];
                $cond = '(' . implode(' AND ', $bindArray) . ')';
                $bind[$productBind] = $productId;
                $bind[$storeBind] = $storeId;
                $bind[$catBind] = $catId;
                $select->orWhere($cond);
            }

            $rowSet = $connection->fetchAll($select, $bind);
            foreach ($rowSet as $row) {
                $result[$row['product_id']] = [
                    'store_id' => $row['store_id'],
                    'visibility' => $row['visibility'],
                    'url_rewrite' => $row['request_path'],
                ];
            }

should be something like:

            $select = $connection->select()->from(
                ['i' => $this->tableMaintainer->getMainTable($storeId)],
                ['product_id', 'store_id', 'visibility']
            )->joinLeft(
                ['u' => $this->getMainTable()],
                'i.product_id = u.entity_id AND i.store_id = u.store_id'
                . ' AND u.entity_type = "' . ProductUrlRewriteGenerator::ENTITY_TYPE . '"',
                ['request_path']
            )->joinLeft(
                ['r' => $this->getTable('catalog_url_rewrite_product_category')],
                'u.url_rewrite_id = r.url_rewrite_id',
                []
            );

            $bind = [];
            foreach ($productIds as $productId) {
                $catId = $this->_storeManager->getStore($storeId)->getRootCategoryId();
                $productBind = 'product_id' . $productId;
                $storeBind = 'store_id' . $storeId;

                    'i.category_id = :' . $catBind
                ];
                $cond = '(' . implode(' AND ', $bindArray) . ' AND (r.url_rewrite_id IS NULL)) AND u.redirect_type = 0';
                $bind[$productBind] = $productId;

            }

            $rowSet = $connection->fetchAll($select, $bind);
            foreach ($rowSet as $row) {
                $result[$row['product_id']] = [

@magento-engcom-team This is a API bug related to product URLs. Can someone take a look on it ?

[hostep]

@daniel-ifrim: could you edit your initial post and change the actual results, because they are the same as the expected results. Thanks!

Other than that, if I test your queries over here on some random shop I picked, the first query returns 16 rows, and the second query 3 rows, of which 2 rows still contain category parts in the url. That's probably because they are of redirect_type '301' over here:

The way to only get a single row where no category's are in the url is by adding AND u.metadata IS NULL. Does this make sense?

[daniel-ifrim]

@hostep

• Function getRewriteByProductStore should return only one row.
  See the functions that call it.
• You have on the first position in the result set the correct row (product url row). In my result set the product URL row is the last row. MySQL returns rows how they are stored if there is no sort order. There should not be a sort order in this SQL query. The SQL query should be narrowed right.
• There is no condition in SQL query WHERE clause for redirect_type.
• Also you can tell that the JOIN query does not do what it should: exclude the categories rows.
  This "AND r.category_id IS NULL " column ('category_id') is not the link column of the 2 tables (url_rewrite_id). As far as I know, in a JOIN condition on 2 tables you have to include the link column in the JOIN clause to exclude the rows from the first table that do not exist in the second table. This is why I suggested: "AND r.url_rewrite_id IS NULL" in WHERE clause.

Thank you

[hostep]

As you can tell by the screenshot I posted above, your solution still returns more than one row.
I do agree that it should only return a single row. So, would adding a WHERE statement on the metadata column be the solution here you think?

@hostep Adding WHERE metadata IS NULL is a light fix. Someone can add data in the future in metadata column. There will be a bug.
I just run the 2 SQL queries on a store, MySQL server 5.7.26.
I can run same type of SQL queries for test on Mariadb also if you need me to.

These are the results on MySQL. I don't want to enforce this solution. Anyone that will craft a patch for this issue will have to check he's or her's fix.

On left side there is original SQL query. On right side there is the modified SQL query.

The original SQL query executed:

The modified SQL query executed:

@hostep Are you sure you didn't make a typo when you were testing ?

Thank you
