If this is a technical question that others may benefit from, considering also asking it on Stackoverflow: https://stackoverflow.com/questions/ask?tags=onflow-cadenceLine 191 mentions a deprecation notice https://www.flowdiver.io/contract/A.49a7cda3a1eecc29.NFTCatalog?tab=deployments
I found a script that uses the old function call..and am trying to figure out how to use the new call..specifically, how to get hold of the
catalog within the function that is passed in
Old script -
import MetadataViews from 0x1d7e57aa55817448
import NFTCatalog from 0x49a7cda3a1eecc29
import NFTRetrieval from 0x49a7cda3a1eecc29
pub fun main(ownerAddress: Address) : {String : [UInt64]} {
let catalog = NFTCatalog.getCatalog() // Want to replace this call as per deprecation notice
let account = getAuthAccount(ownerAddress)
let items : {String : [UInt64]} = {}
for key in catalog.keys {
let value = catalog[key]!
let tempPathStr = "catalogIDs".concat(key)
if let tempPublicPath = PublicPath(identifier: tempPathStr) {
account.link<&{MetadataViews.ResolverCollection}>(
tempPublicPath,
target: value.collectionData.storagePath
)
let collectionCap = account.getCapability<&AnyResource{MetadataViews.ResolverCollection}>(tempPublicPath)
if !collectionCap.check() {
continue
}
let ids = NFTRetrieval.getNFTIDsFromCap(collectionIdentifier : key, collectionCap : collectionCap)
if ids.length > 0 {
items[key] = ids
}
}
}
return items
}
New script -
pub fun main(ownerAddress: Address) : {String : [UInt64]} {
let account = getAuthAccount(ownerAddress)
let items : {String : [UInt64]} = {}
NFTCatalog.forEachCatalogKey(fun (key: String): Bool {
// but how do I get hold of the catalog here? to do a catalog[key]
nvm - found all my answers here 🙂 https://github.com/onflow/nft-catalog#using-the-catalog-for-marketplaces-and-other-nft-applications
