Hello. I've added a metaField to my Shopify Store that store the location of the Products and Collections. I can fetch the value added to the metafield from my Model class. What I'm trying to do is to filter the products fetched based on the value added to the metaField. I'm not able to find a way to do that.
Below is the ProductModel that I'm using where I'm accessing the metaField value. I'm able to access the value of the metaField this way:
import Foundation
import Buy
final class ProductModel: Model {
typealias ModelType = Storefront.Product
let model: ModelType
let id: String
let title: String
let summary: String
let price: String
let images: PageableArray<ImageModel>
let variants: PageableArray<VariantModel>
let storeLocation: String?
// ----------------------------------
// MARK: - Init -
//
required init(from model: ModelType) {
self.model = model
let variants = model.variants.nodes.models.sorted {
$0.price < $1.price
}
let lowestPrice = variants.first?.price
self.id = model.id.rawValue
self.title = model.title
self.summary = model.descriptionHtml
self.price = lowestPrice == nil ? "No price" : Currency.stringFrom(lowestPrice!)
self.images = PageableArray(
with: model.images.nodes,
pageInfo: PageMetaData(pageInfo: model.images.pageInfo)
)
self.variants = PageableArray(
with: model.variants.nodes,
pageInfo: PageMetaData(pageInfo: model.variants.pageInfo)
)
if let metaFieldValue = model.metafield?.value {
self.storeLocation = metaFieldValue
BSLog.debugLog("MetaField : \(metaFieldValue)")
} else {
self.storeLocation = "No Location"
}
}
}
Below is how I'm fetching the products:
func fetchProducts(with ids: [String], completion: @escaping (PageableArray<ProductModel>?) -> Void) {
let query = ClientQueryProduct.queryForProducts(with: ids)
let task = self.client.queryGraphWith(query) { (query, error) in
error.debugPrint()
if let query = query, let results = query.nodes as? [Storefront.Product] {
let products = PageableArray(
with: results,
pageInfo: PageMetaData()
)
completion(products)
} else {
print("Failed to load products: \(String(describing: error))")
completion(nil)
}
}
task.resume()
}
How I'm querying the product:
static func queryForProducts(with ids: [String]) -> Storefront.QueryRootQuery {
let graphIDs: [GraphQL.ID] = ids.map { GraphQL.ID.init(rawValue: $0) }
return Storefront.buildQuery { $0
.nodes(ids: graphIDs) { $0
.onProduct { $0
.fragmentForProduct()
}
}
}
}
The Product Query to fetch the details of the product.
extension Storefront.ProductQuery {
@discardableResult
func fragmentForProduct() -> Storefront.ProductQuery { return self
.id()
.title()
.descriptionHtml()
.variants(first: 250) { $0
.fragmentForStandardVariant()
}
.images(first: 250) { $0
.fragmentForStandardProductImage()
}
.metafield(namespace: "custom", key: "location") { $0
.value()
}
}
}
Is there a way I can filter the products using the metaField value?
