specifying idProperty in dbConfig for IndexedDB prevents store from being created...

[ddolga]

In dstore/db/IndexedDB the idProperty is specified inside the store object:

 var dbConfig = {
            version: 1,
            name: "testwarn-db",
                options: {
                    idProperty: "chkSum",
                    chkSum: {
                        indexed: true
                    }
                }
            }
        }

This is where the constructor method looks for it:

 if (!db.objectStoreNames.contains(storeName)) {
                                var idProperty = storeConfig.idProperty || 'id';
                                var idbStore = db.createObjectStore(storeName, {
                                    keyPath: idProperty,
                                    autoIncrement: storeConfig[idProperty] &&
                                    storeConfig[idProperty].autoIncrement || false
                                });

However later on when it scans the store for indexes:

 for (var index in storeConfig) {
                                if (!idbStore.indexNames.contains(index) && index !== 'autoIncrement'
                                   // && index !== "idProperty" // hack to get to work
                                    && storeConfig[index].indexed !== false) {
                                  idbStore.createIndex(index, index, storeConfig[index]);
                                }
                            }

an error is thrown in idbStore.createIndex(index, index, storeConfig[index]) : "third parameter is not an object". This is because its passing the idProperty into the createIndex method. I had to modify the code to also check that index !== "idProperty" in order to get this to work.

Got same problem. I'm trying to make a composite keyPath and write it like so

const dbConfig = {
  version: 1,
  stores: {
    answers: {
      idProperty: ['attempt', 'task'],
      attempt: {
      },
      task: {
        indexed: false
      }
    }
  }
}

It creates indexes 'idProperty' and 'attempt' instead of single 'attempt'.
