Return value

string The row identifier.

1 call to CachePluginBase::getRowId()

CachePluginBase::getRowCacheKeys in core/modules/views/src/Plugin/views/cache/CachePluginBase.php

Returns the row cache keys.

File

core/modules/views/src/Plugin/views/cache/CachePluginBase.php, line 355

Class

CachePluginBase

The base plugin to handle caching.

Namespace

Drupal\views\Plugin\views\cache

Code

public function getRowId(ResultRow $row) {
    // Here we compute a unique identifier for the row by computing the hash of
    // its data. We exclude the current index, since the same row could have a
    // different result index depending on the user permissions. We exclude also
    // entity data, since serializing entity objects is very expensive. Instead
    // we include entity cache tags, which are enough to identify all the
    // entities associated with the row.
    $row_data = array_diff_key((array) $row, array_flip([
        'index',
        '_entity',
        '_relationship_entities',
    ])) + $this->getRowCacheTags($row);
    // This ensures that we get a unique identifier taking field handler access
    // into account: users having access to different sets of fields will get
    // different row identifiers.
    $field_ids = array_keys($this->view->field);
    $row_data += array_flip($field_ids);
    // Finally we compute a hash of row data and return it as row identifier.
    return hash('sha256', serialize($row_data));
