Running the task

The task can be run from a browser window or the command line. To run the task in the browser go to dev/tasks and find Import products from salsify or visit dev/tasks/SalsifyImportTask.

It is recommended to use the command line, because the task can easily time out in a browser. To run the task in the command line sake must be installed and the command sake dev/tasks/SalsifyImportTask must be run.

Example configuration

Extensions

SalsifyIDExtension

It is recommended to add Dynamic\Salsify\ORM\SalsifyIDExtension as an extension of any object being mapped to. It will add a SalsifyID and SalsifyUpdatedAt field that can be mapped to. The SalsifyID field is used in single object updates.

MyObject:
  extensions:
    - Dynamic\Salsify\ORM\SalsifyIDExtension

The SalsifyID and SalsifyUpdatedAt fields will still need to be explicitly mapped in the mapper config.

Dynamic\Salsify\Model\Mapper.example:
  mapping:
    \Page:
      SalsifyID:
        salsifyField: 'salsify:id'
        unique: true
      SalsifyUpdatedAt: 'salsify:updated_at'

SalsifyFetchExtension

The SalsifyFetchExtension is automatically added to left and main. It will provide a button on data objects that have a salsify mapping to refetch.

To have the button force update refetch_force_update and refetch_force_update_relations can be set to true on the data object being mapped to. When set to true refetch_force_update will force update any non-relation field in salsify. When set to true refetch_force_update_relations will force update any relation field in salsify.

\Page:
  refetch_force_update: true
  refetch_force_update_relations: true

See the Single Object Import section for more setup information.

Importer

Importers will run fetchers and mappers. Each importer needs to be passed an importerKey to its constructor. For the rest of the readme example will be used for the services.

SilverStripe\Core\Injector\Injector:
  Dynamic\Salsify\Model\Importer.example:
    class: Dynamic\Salsify\Model\Importer
    constructor:
      importerKey: example

Fetcher

To set up a fetcher an api key and a channel id need to be provided. The apiKey can be in the root Fetcher config, but can also be overridden in a specific service config. The channel id can be found by visiting the channel in Salsify and copying the last section of the url. https://app.salsify.com/app/orgs/<org_id>/channels/<channel_id> To find the api key follow this

Dynamic\Salsify\Model\Fetcher:
  apiKey: 'api key here'

Dynamic\Salsify\Model\Fetcher.example:
    channel: 'channel id'

or

Dynamic\Salsify\Model\Fetcher.example:
  apiKey: 'api key here'
  channel: 'channel id'

An organization ID can also be included to avoid an account having access to multiple organizations.

Dynamic\Salsify\Model\Fetcher:
  organizationID: 'org id'

or

Dynamic\Salsify\Model\Fetcher.example:
  organizationID: 'org id'

https://developers.salsify.com/docs/organization-id

The fetcher can also have the timeout changed for http requests. This is not a timeout for Salsify to generate an export. Timeout is in milliseconds and defaults to 2000 ms or 2 seconds. Like an apiKey the timeout can be set in the root fetcher config and be overridden by a service config.

Dynamic\Salsify\Model\Fetcher:
  timeout: 4000

or

Dynamic\Salsify\Model\Fetcher.example:
  timeout: 4000

Mapper

To set up a mapper, which will map fields from Salsify to SilverStripe, some configuration is needed.

Dynamic\Salsify\Model\Mapper.example:
  mapping:
    \Page:
       SKU:
        salsifyField: SKU
        unique: true
       Title: Product Title

Each mapper instance will need a service config. Under the mapping config one or more classes can be specified for import. Each class can have one or more fields to map, and must have at least one that is unique. All fields have the key of the SilverStripe field to map to. Title: Product Title will map Product Title from Salsify to Title in SilverStripe.

Unique Fields

Like non-unique fields, the key is the SilverStripe field to map to. salsifyField is the field from Salsify to map. unique is either true or false and will be used as a filter to check against existing records.

Dynamic\Salsify\Model\Mapper.example:
  mapping:
    \Page:
      SKU:
        salsifyField: SKU
        unique: true

The unique fields will be added to an array, with the values for each product and will be used as a filter to find existing. This allows for multiple compound unique fields.

Field Types

The built in field types are Raw, Literal, File, Image, HasOne, HasMany. There are some specialized field types that are SalsifyID, SalsifyUpdatedAt, SalsifyRelationsUpdatedAt that are meant for mapping to specific fields without modifications. More types can also be added.

Raw

By default the Raw type is used. It will write the salsify property value into the object field.

Dynamic\Salsify\Model\Mapper.example:
  example:
    mapping:
      \Page:
        Title: 'Web Title'

SalsifyID, SalsifyUpdatedAt, and SalsifyRelationsUpdatedAt

Fields that have these types cannot be modified, but will be handled like a raw type.

Dynamic\Salsify\Model\Mapper.example:
  example:
    mapping:
      \Page:
        SalsifyID:
          salsifyField: 'salsify:id'
          type: SalsifyID
        SalsifyUpdatedAt:
          salsifyField: 'salsify:updated_at'
          type: SalsifyUpdatedAt
        SalsifyRelationsUpdatedAt:
          salsifyField: 'salsify:relations_updated_at'
          type: SalsifyRelationsUpdatedAt
Boolean

Useful for mapping Yes/No value fields from salsify to the boolean database type.

Dynamic\Salsify\Model\Mapper.example:
  example:
    mapping:
      \Page:
        Obsolete:
          salsifyField: 'obsolete'
          type: Boolean
isTrue

The boolean handler also comes with a handy isTrue helper method. This is helpful when modifications or skipping has to be done on a Yes/No formatted property.

Literal

To set a field that doesn't have a salsify field a literal field can be used.

Dynamic\Salsify\Model\Mapper.example:
  example:
    mapping:
      \Page:
        Author:
          value: 'Chris P. Bacon'
          type: Literal

The above example will set the Author field to Chris P. Bacon for all mapped pages.

Files and Images

To get an image or file from salsify to map to an object a type needs to be specified.

Dynamic\Salsify\Model\Mapper.example:
  example:
    mapping:
      \Page:
        FrontImage:
          salsifyField: Front Image
          type: Image

Images and files can also be mapped by ID.

Dynamic\Salsify\Model\Mapper.example:
  mapping:
    \Page:
      FrontImageID:
        salsifyField: Front Image
        type: Image

If the mapping is specified as an image and it is not a valid image extension, salsify will be used to try and convert the file into a png.

Image Transformation

To cut down on 500 errors caused by trying to resize images when visiting a page images can be transformed by salsify. When an image transformation is updated in the config it will also re-download the image with the new transformations.

Dynamic\Salsify\Model\Mapper.example:
  mapping:
    \Page:
      FrontImageID:
        salsifyField: Front Image
        type: Image
        transform:
          - 'c_fit'
          - 'w_1000'
          - 'h_1000'
          - 'dn_300'
          - 'cs_srgb'

The above will download http://a1.images.salsify.com/image/upload/c_fit,w_1000,h_1000,dn_300,cs_srgb/sample.jpg instead of http://a1.images.salsify.com/image/upload/sample.jpg.

To see what transformations salsify supports please visit https://getstarted.salsify.com/help/transforming-image-files.

It is recommended to do this to all large files.

HasOne and HasMany

has_one and has_many relations can be done just about the same. The HasOne's salsifyField doesn't matter. The ManyRelation type requires a salsify field that is an array. ManyRelation can also have a sort column specified. All modifications to the data will be passed through to the mapping relation.

HasOne example:
Dynamic\Salsify\Model\Mapper.example:
  mapping:
    \Page:
      Document:
        salsifyField: 'salsify:id'
        type: 'HasOne'
        relation:
          \Documentobject:
            Title: Document Title
ManyRelation example:
namespace {
    use SilverStripe\CMS\Model\SiteTree;

    class Page extends SiteTree
    {

        /**
         * @var array
         */
        private static $many_many = [
            'Features' => Feature::class,
        ];

        ];
    }

        public function featureModifier($class, $dbField, $config, $data)
        {
            $features = [];
            foreach ($this->owner->config()->get('featureFields') as $featuredField) {
                if (array_key_exists($featuredField, $data) && $this->is_true($data[$featuredField])) {
                    $features[] = [
                        'FeatureName' => $featuredField,
                    ];
                }

        private function is_true($val, $return_null = false)
        {
            $boolval = (bool)$val;

            if (is_string($val)) {
                $boolval = filter_var($val, FILTER_VALIDATE_BOOLEAN, FILTER_NULL_ON_FAILURE);

            }

            return $boolval;
        }
    }
}
Dynamic\Salsify\Model\Mapper.example:
  extensions:
    - SalsifyExtension
  featureFields:
      - "Feature One"
      - "Feature Two"
  mapping:
    \Page:
      Features:
        salsifyField: 'Features'
        type: 'ManyRelation'
        modification: 'featureModifier'
        sortColumn: 'SortOrder'
        relation:
          Feature:
            Name:
              salsifyField: 'FeatureName'
              unique: true
Salsify Relations

Relationships between products can also be created in salsify. By default it will map to a has_many and many_many relation. The salsifyField is the name of the relation type.

Dynamic\Salsify\Model\Mapper.example:
  mapping:
    \Page:
      RelatedProducts:
        salsifyField: 'You May Also Like'
        type: 'SalsifyRelation'

To map to a has_one relation a single object can be returned.

Dynamic\Salsify\Model\Mapper.example:
  mapping:
    \Page:
      AlternateProduct:
        salsifyField: 'Alternate'
        type: 'SalsifyRelation'
        single: true

Field Fallback

A fallback field can be specified for salsify. The fallback will be used when the normal salsifyField is not in the data from salsify for the object being mapped. The fallback can be a string or array.

Dynamic\Salsify\Model\Mapper.example:
  mapping:
    \Page:
      Title:
        salsifyField: 'Product Web Title'
        fallback: 'Product Title'

or

Dynamic\Salsify\Model\Mapper.example:
  mapping:
    \Page:
      Title:
        salsifyField: 'Product Web Title'
        fallback:
          - 'Product Title'
          - 'SKU'

Keeping Field Values Without a Salsify Field

By default all values that are to be mapped will wipe values if there is no salsify field in the data for an object. This can be changed so it keeps values for a field.

Dynamic\Salsify\Model\Mapper.example:
  mapping:
    \Page:
      Title:
        salsifyField: 'Product Web Title'
        keepExistingValue: true

This will keep the previous value of the title, even if the field is no longer in the data.

Extending onBeforeMap

onBeforeMap is run after the fetcher runs, but before the mapper starts to map. It is passed the file url from the channel export and if the map is of multiple or a single product.

Dynamic\Salsify\Model\Mapper.example:
  extensions:
    - ExampleFeatureExtension
<?php
namespace {
    use SilverStripe\Core\Extension;
    use JsonMachine\JsonMachine;

    /**
     * Class ExampleFeatureExtension
     */
    class ExampleFeatureExtension extends Extension
    {
        /**
         * Gets all the attributes that are in a field group and sets them in the mapper's config
         * @param $file
         * @param bool $multiple
         */
        public function onBeforeMap($file, $multiple)
        {
            $attributes = [];
            $attributeStream = JsonMachine::fromFile($file, '/1/attributes');
            foreach ($this->owner->yieldSingle($attributeStream) as $attribute) {
                if (array_key_exists('salsify:attribute_group', $attribute)) {
                    if ($attribute['salsify:attribute_group'] == 'Product Features') {
                        $attributes[] = $attribute['salsify:id'];
                    }
                }
            }

            $this->owner->config()->set('featureFields', $attributes);
        }
    }
}

Extending onAfterMap

onAfterMap is run after the fetcher runs, but before the mapper starts to map. It is passed the file url from the channel export and if the map is of multiple or a single product. This extension point is good for cleaning up products that are not in the channel export.

Dynamic\Salsify\Model\Mapper.example:
  extensions:
    - ExampleCleanUpExtension
<?php
namespace {
    use SilverStripe\Core\Extension;
    use JsonMachine\JsonMachine;
    use Dynamic\Salsify\Task\ImportTask;
    use Dynamic\Salsify\Model\Mapper;

    /**
     * Class ExampleCleanUpExtension
     */
    class ExampleCleanUpExtension extends Extension
    {
        /**
         * @param $file
         * @param bool $multiple
         */
        public function onAfterMap($file, $multiple)
        {
            // don't clean up on a single product import
            if ($multiple == Mapper::$SINGLE) {
                return;
            }

            $productStream = JsonMachine::fromFile($file, '/4/products');
            $productCodes = [];

            foreach ($this->owner->yieldKeyVal($productStream) as $name => $data) {
                $productCodes[] = $data['salsify:id'];
            }

            $invalidProducts = Product::get()->exclude([
                'SalsifyID' => $productCodes,
            ]);

            $count = 0;
            foreach ($this->owner->yieldSingle($invalidProducts) as $invalidProduct) {
                /** @var Product $invalidProduct */
                $invalidProduct->doArchive();
                $count++;
            }
            ImportTask::output("Archived {$count} products");
        }
    }
}

Extending beforeObjectWrite

This extension point is good for detecting which fields were changed. This is helpful to create redirects for pages if a parent has changed during mapping.

Dynamic\Salsify\Model\Mapper.example:
  extensions:
    - ExampleRedirectExtension
<?php
namespace {
    use SilverStripe\Core\Extension;
    use SilverStripe\ORM\DataObject;
    use SilverStripe\RedirectedURLs\Model\RedirectedURL;
    use Dynamic\Salsify\Task\ImportTask;

    /**
     * Class ExampleRedirectExtension
     */
    class ExampleRedirectExtension extends Extension
    {
        /**
         * This will create a redirect if a page's parent changes
         * @param DataObject $object
         */
        public function beforeObjectWrite($object)
        {
            if (!$object instanceof \Page) {
                return;
            }

            if (!$object->isChanged()) {
                return;
            }

            $changed = $object->getChangedFields(false, DataObject::CHANGE_VALUE);

            if (!array_key_exists('ParentID', $changed) && !array_key_exists('URLSegment', $changed)) {
                return;
            }

            $oldParent = $object->ParentID;
            $oldSegment = $object->URLSegment;
            if (array_key_exists('ParentID', $changed)) {
                $parent = $changed['ParentID'];
                $oldParent = $parent['before'];
            }

            if (array_key_exists('URLSegment', $changed)) {
                $segment = $changed['URLSegment'];
                $oldSegment = $segment['before'];
            }

            $this->createRedirect($oldParent, $oldSegment, $object->ID);
        }

        /**
         * @param \Page|int $oldParent
         * @param string $oldSegment
         * @param int $objectID
         */
        private function createRedirect($oldParent, $oldSegment, $objectID)
        {
            if (is_int($oldParent)) {
                $oldParent = \Page::get()->byID($oldParent);
            }

            $redirect = RedirectedURL::create();
            $redirect->RedirectCode = 301;
            $redirect->FromBase = preg_replace('/\?.*/', '', $oldParent->Link($oldSegment));
            $redirect->LinkToID = $objectID;
            $redirect->write();
            ImportTask::output("Created redirect from {$redirect->FromBase} to {$redirect->LinkTo()->Link()}");
        }
    }
}

Extending afterObjectWrite

To publish an object after mapping the afterObjectWrite method can be extended. It is passed the DataObject that was written, if the object was in the database, and if the object was published. If the object does not have the versioned extension applied $wasPublished will be false.

Dynamic\Salsify\Model\Mapper.example:
  extensions:
    - ExamplePublishExtension
<?php
namespace {
    use SilverStripe\Core\Extension;
    use SilverStripe\Versioned\Versioned;

    /**
     * Class ExamplePublishExtension
     */
    class ExamplePublishExtension extends Extension
    {
        /**
         * This will publish all new mapped objects and mapped objects that are already published.
         * @param DataObject|Versioned $object
         * @param bool $wasWritten
         * @param bool $wasPublished
         */
        public function afterObjectWrite($object, $wasWritten, $wasPublished)
        {
            if ($object->hasExtension(Versioned::class)) {
                if (!$wasWritten || $wasPublished) {
                    $object->publishRecursive();
                }
            }
        }
    }
}

Single Object Import

Adding a re-fetch button in the cms requires some configuration. An organization is required to fetch a single product. A SalsifyID field is also required for single object imports. Only a mapping service with the name of single is required and will act just like a normal mapper config; however, a fetcher service config can also be defined to specify the organization.

Dynamic\Salsify\Model\Fetcher.single:
  organizationID: 'org id'

Dynamic\Salsify\Model\Mapper.single:
