- You need to initialize first, otherwise
WL.JSONStore.get(collectionName)
will always return undefined. If you never initialize JSONStore, you can not use it. - The
replace
API works with JSONStore documents (objects that have keys for_id
andjson
). - You only need one
.fail
, the error object will tell you the source of the error (errorObject.src
).
See the untested pseudocode below for what you want to do:
function wlCommonInit () {
var collectionName = 'Person';
var Data = {
Name: 'name',
Age: 27
};
var JSONStoreCollections = {};
JSONStoreCollections[collectionName] = {};
JSONStoreCollections[collectionName].searchFields = {Name: 'string'};
WL.JSONStore.init(JSONStoreCollections)
.then(function () {
WL.Logger.debug('Init done');
return WL.JSONStore.get(collectionName).findAll();
})
.then(function (res) {
WL.Logger.debug('Find All returned:', res);
if (res.length < 1) {
return WL.JSONStore.get(collectionName).add(Data);
} else {
res[0].json = {
Name:'name1',
Age:30
};
return WL.JSONStore.get(collectionName).replace(res[0]);
}
})
.then(function () {
WL.Logger.debug('Add or Replace done');
return WL.JSONStore.get(collectionName).find({Name: 'name'});
})
.then(function (res) {
WL.Logger.info('Final Find returned:', res);
})
.fail(function (err) {
WL.Logger.error(err);
});
}
Expected output the first time executed:
Init done
Find All returned: []
Add or Replace done
Final Find returned: [{"_id":1,"json":{"Name":"name","Age":27}}]
Expected output other than the first time executed:
Init done
Find All returned: [{"_id":1,"json":{"Name":"name","Age":27}}]
Add or Replace done
Final Find returned: [{"_id":1,"json":{"Name":"name1","Age":30}}]
