Usage
$importer = new CSVImporter; //Will read CSV file $importer->setData(new CSVReader([ 'filename' => $this->file->tempName, 'fgetcsvOptions' => [ 'delimiter' => ';' ] ])); //Import multiple (Fast but not reliable). Will return number of inserted rows $numberRowsAffected = $importer->import(new MultipleImportStrategy([ 'tableName' => VendorSwType::tableName(), 'configs' => [ [ 'attribute' => 'name', 'value' => function($line) { return $line[1]; }, 'unique' => true, //Will filter and import unique values only. can by applied for 1+ attributes ] ], ])); //Import Active Records (Slow, but more reliable). Will return array of primary keys $primaryKeys = $importer->import(new ARImportStrategy([ 'className' => BusinessType::className(), 'configs' => [ [ 'attribute' => 'name', 'value' => function($line) { return $line[2]; }, ], [ 'attribute' => 'items', 'virtual' => true, //set non AR DB attribute (behavior or public model attribute) 'value' => function($line) { return Item::find()->select(['id'])->column('id'); }, ] ], ])); // More advanced example. You can use queries to set related data. // Use query caching for performance $importer->import(new MultipleImportStrategy([ 'tableName' => ProductInventory::tableName(), 'configs' => [ [ 'attribute' => 'product_name', 'value' => function($line) { //You cand perform your filters and excludes here. Empty exclude example: return $line[7] != "" AppHelper::importStringFromCSV($line[7]) : null; }, ], [ 'attribute' => 'id_vendor_sw_type', 'value' => function($line) { $name = AppHelper::importStringFromCSV($line[1]); $vendor = VendorSwType::getDb()->cache(function ($db) use($name) { return VendorSwType::find()->where(['name' => $name])->one(); }); return isset($vendor) ? $vendor->id : null; }, ], ], ])); //Special case only available with Active Record Strategy. //Get primary key list of new imported items for later use. $primaryKeys = $importer->import(new ARImportStrategy([ 'className' => Fabrica::className(), 'configs' => [ [ 'attribute' => 'name', 'value' => function($line) { return $line[0]; }, ] ], ])); //You can use the primary key list for the next import of related data. //The order of primary key items will be the same as in csv file. $importer->import(new MultipleImportStrategy([ 'tableName' => Product::tableName(), 'configs' => [ [ 'attribute' => 'id_fabrica', 'value' => function($line) use (&$primaryKeys) { return array_shift($primaryKeys); }, 'unique' => true, ], ], ])); //You can skip CSV Row / Active Record import if some csv row doesn't meet the requirements. $importer->import(new MultipleImportStrategy([ 'tableName' => ProductCategory::tableName(), 'configs' => [ [ 'attribute' => 'name', 'value' => function($line) { return $line[0]; }, ], [ 'attribute' => 'description', 'value' => function($line) { return $line[1]; }, ], [ 'attribute' => 'estado', 'value' => function($line) { return $line[2]; }, ] ], //All ACTIVE categories that don't have name set to 'MS_SQLSERVER' or empty will be imported. 'skipImport' => function($line){ if($line[0] == 'MS_SQLSERVER' || $line[0] == ""){ return true; } if($line[2] == 'NOT ACTIVE'){ return true; } } ])); //Import or update multiple (Fast but not reliable). Will return number of inserted, updated and unchanged rows //ARUpdateStrategy can be used instead of MultipleUpdateStrategy if you want to use AR validation. //The returned value will be the number of inserted, updated and unchanged rows in both cases. $records = $importer->import(new MultipleUpdateStrategy([ 'className' => Customer::className(), 'csvKey' => function ($line) { return $line[0]; }, 'rowKey' => function ($row) { return $row['gecom_id']; }, 'skipImport' => function ($line) { return !$line[0]; }, 'configs' => [ [ 'attribute' => 'customer_id', 'value' => function($line) { return $line[0]; }, ], ], ]));
