Hi I am new MVEL framework.
I have json,
fund: {
"name":"mounika",
"surName":"Gaja"
}
I need to check whether that node "name" is present in the fund object in MVEL.
Please help me with this out.

I am trying to create an item in a SharePoint list using Microsoft Graph API and all the fields are inserting except when I add a user column I get the following error:
"code": "generalException",
"message": "General exception while processing".
Based on research, to insert into a user column the user's LookupId is required. My request body for the user column is as follows:
{
"fields": {
"[ColumnName]LookupId": "12"
}
}
If anybody could advise what I'm doing wrong or if I can insert using the user's email that would be better.
Cheers.
Everything is good with your request, but this body will work only for lookup/user columns where setting "Allow multiple selections" is false. I guess in your case it's true.
You can check it with the endpoint
GET https://graph.microsoft.com/v1.0/sites/{{SiteId}}/lists/{{ListName}}/contentTypes?expand=columns(select=name,type,personOrGroup)
where personOrGroup.allowMultipleSelection will show the flag.
For user or lookup type column where multiple selection is allowed, use the following body (and obviously you may pass multiple values in array):
{
"fields": {
"[columnName]LookupId#odata.type":"Collection(Edm.String)",
"[columnName]LookupId":["12"]
}
}
As for referring to user fields with email, I don't think it's possible with Graph API, but you may check Sharepoint REST API v1 if it supports that
Using NodeJS, I am trying to update relationship field which link to another app (contacts-leads). I have try all combination but still getting error. I think I have the necessary data to post, app_id, item_id, external_id..etc. I need help with forming JSON structure.
p.request('put','item/<Item_Id>/value', data)
var data {....}
app_id:'<app_id>'
value:'<value>' (value is the app_item_id of the link to application; that is the number in URL)
app_item_id: '<app_item_id>'
external_id:'<external_id>'
I was able to update non-relationship field without problem.
Thanks
Well, going to answer my own question. That will work for single app link, not sure about multiple ones.
data = {
"<external_id>": {
"apps": [{"app_id": <app_id>}],
"value: <app_item_id>
}
}
This question may very well be a general API question, but the API I am using is the Connectwise Tickets API.
I'm writing in VB and I'm getting my list of tickets(i) then I'm setting the following variable:
currentTicket = tickets(i)
So that I can reference value like currentTicket.Source.Name and save the info to a DB.
As long as the Connectwise user put something into the "Source" field, everything works fine. I can reference that property and log it to the database or whatever else I want to do. If they left it blank though, even trying to look at currentTicket.Source.Name stops my program in it's tracks. It doesn't crash or error out, it just doesn't go past the line of code referencing the empty field.
Since it won't even let me reference currentTicket.Source.Name for example, I am unable to check to see if currentTicket.Source.Name = "" or Is Nothing.
What am I missing? Is there a way to check and see if the property even exists for a given API response?
Any help would be appreciated.
EDIT:
OK so I decided to take the Ticket object and grab the raw json and send it to the command line output.
When a ticket has the source field filled in, this is what that section of the JSON looks like:
...
},
"servicelocation": {
"id":4,
"name":"remote",
"_info":{
"location_href":"https://API_url"
}
},
"source":{
"id":4,
"name":"Email Connector",
"_info": {
"source_href":"https://API_url"
}
},
"severity": "Medium",
"impact":"Medium",
...
When the source field in the application has been left blank, the JSON looks like this instead:
...
},
"servicelocation": {
"id":4,
"name":"remote",
"_info":{
"location_href":"https://API_url"
}
},
"severity": "Medium",
"impact":"Medium",
...
That behavior is probably normal, I'm obviously just missing the knowledge of how to deal with it. I feel like I should be able to test if the property of the object is non-existent the same way I test if it's null or "", using Tickets(i).Source.Name, but I get no exceptions, no errors, no crashes, the program just sits their waiting for a response to "What's Source Name's value?"
I mean I suppose I could parse out the entire JSON response, create my own private object, assign values as they exist and then set my own property values so I could then set mySourceName = "" When it doesn't exist in the JSON response, but that seems like a lot of work when I only care about like 10 fields and it's a pretty large json response.
Is that the normal way of doing things with APIs?
Overview
I'm using Ember data and have a JSONAPI. Everything works fine until I have a more complex object (let's say an invoice for a generic concept) with an array of items called lineEntries. The line entries are not mapped directly to a table so need to be stored as raw JSON object data. The line entry model also contains default and computed values. I wish to store the list data as a JSON object and then when loaded back from the store that I can manipulate it as normal in Ember as an array of my model.
What I've tried
I've looked at and tried several approaches, the best appear to be (open to suggestions here!):
Fragments
Replace problem models with fragments
I've tried making the line entry model a fragment and then referencing the fragment on the invoice model as a fragmentArray. Line entries add to the array as normal but default values don't work (should they?). It creates the object and I can store it in the backend but when I return it, it fails with either a normalisation issue or a serialiser issue. Can anyone state the format the data be returned in? It's confusing as normalising the data seems to require JSONAPI but the fragment requires JSON serialiser. I've tried several combinations but no luck so far. My line entries don't have actual ids as the data is saved and loaded as a block. Is this an issue?
DS.EmbeddedRecordsMixin
Although not supported in JSONAPI, it sounds possible to use JSONAPI and then switch to JSONSerializer or RESTSerializer for the problem models. If this is possible could someone give me a working example and the JSON format that should be returned by the API? I have header authorisation and other such data so would I still be able to set this at the application level for all request not using my JSONAPI?
Ember-data-save-relationships
I found an add on here that provides an add on to do this. It seems more involved than the other approaches but when I've tried this I can send the data up by setting a the data as embedded. Great! But although it saves it doesn't unwrap it correct and I'm back with the same issues.
Custom serialiser
Replace the models serialiser with something that takes the data and sends it as plain JSON data and then deserialises back into something Ember can use. This sounds similar to the above but I do the heavy lifting. The only reason to do this is because all examples for the above solutions are quite light and don't really show how to set this up with an actual JSONAPI set up that would need it.
Where I am and what I need
Basically all approaches lead to saving the JSON fine but the return JSON from the server not being the correct format or the deserialisation failing but it's unclear what it should be or what needs to change without breaking the existing JSONAPI models that work fine.
If anyone know the format for return API data it may resolve this. I've tried JSONAPI with lineEntries returning the same format as it saved. I've tried placing relationship sections like the add on suggested and I've also tried placing relationship only data against the entries and an include section with all the references. Any help on this would be great as I've learned a lot through this but deadlines a looming and I can't see a viable solution that doesn't break as much as it fixes.
If you are looking for return format for relational data from the API server you need to make sure of the following:
Make sure the relationship is defined in the ember model
Return all successes with a status code of 200
From there you need to make sure you return relational data correctly. If you've set the ember model for the relationship to {async: true} you need only return the id of the relational model - which should also be defined in ember. If you do not set {async: true}, ember expects all relational data to be included.
return data with relationships in JSON API specification
Example:
models\unicorn.js in ember:
import DS from 'ember-data';
export default DS.Model.extend({
user: DS.belongsTo('user', {async: true}),
staticrace: DS.belongsTo('staticrace',{async: true}),
unicornName: DS.attr('string'),
unicornLevel: DS.attr('number'),
experience: DS.attr('number'),
hatchesAt: DS.attr('number'),
isHatched: DS.attr('boolean'),
raceEndsAt: DS.attr('number'),
isRacing: DS.attr('boolean'),
});
in routes\unicorns.js on the api server on GET/:id:
var jsonObject = {
"data": {
"type": "unicorn",
"id": unicorn.dataValues.id,
"attributes": {
"unicorn-name" : unicorn.dataValues.unicornName,
"unicorn-level" : unicorn.dataValues.unicornLevel,
"experience" : unicorn.dataValues.experience,
"hatches-at" : unicorn.dataValues.hatchesAt,
"is-hatched" : unicorn.dataValues.isHatched,
"raceEndsAt" : unicorn.dataValues.raceEndsAt,
"isRacing" : unicorn.dataValues.isRacing
},
"relationships": {
"staticrace": {
"data": {"type": "staticrace", "id" : unicorn.dataValues.staticRaceId}
},
"user":{
"data": {"type": "user", "id" : unicorn.dataValues.userId}
}
}
}
}
res.status(200).json(jsonObject);
In ember, you can call this by chaining model functions. For example when this unicorn goes to race in controllers\unicornracer.js:
raceUnicorn() {
if (this.get('unicornId') === '') {return false}
else {
return this.store.findRecord('unicorn', this.get('unicornId', { backgroundReload: false})).then(unicorn => {
return this.store.findRecord('staticrace', this.get('raceId')).then(staticrace => {
if (unicorn.getProperties('unicornLevel').unicornLevel >= staticrace.getProperties('raceMinimumLevel').raceMinimumLevel) {
unicorn.set('isRacing', true);
unicorn.set('staticrace', staticrace);
unicorn.set('raceEndsAt', Math.floor(Date.now()/1000) + staticrace.get('duration'))
this.set('unicornId', '');
return unicorn.save();
}
else {return false;}
});
});
}
}
The above code sends a PATCH to the api server route unicorns/:id
Final note about GET,POST,DELETE,PATCH:
GET assumes you are getting ALL of the information associated with a model (the example above shows a GET response). This is associated with model.findRecord (GET/:id)(expects one record), model.findAll(GET/)(expects an array of records), model.query(GET/?query=&string=)(expects an array of records), model.queryRecord(GET/?query=&string=)(expects one record)
POST assumes you at least return at least what you POST to the api server from ember , but can also return additional information you created on the apiServer side such as createdAt dates. If the data returned is different from what you used to create the model, it'll update the created model with the returned information. This is associated with model.createRecord(POST/)(expects one record).
DELETE assumes you return the type, and the id of the deleted object, not data or relationships. This is associated with model.deleteRecord(DELETE/:id)(expects one record).
PATCH assumes you return at least what information was changed. If you only change one field, for instance in my unicorn model, the unicornName, it would only PATCH the following:
{
data: {
"type":"unicorn",
"id": req.params.id,
"attributes": {
"unicorn-name" : "This is a new name!"
}
}
}
So it only expects a returned response of at least that, but like POST, you can return other changed items!
I hope this answers your questions about the JSON API adapter. Most of this information was originally gleamed by reading over the specification at http://jsonapi.org/format/ and the ember implementation documentation at https://emberjs.com/api/data/classes/DS.JSONAPIAdapter.html
I am looking for a more detailed list of possible API responses when using Yodlee's REST API. Think of it as an XSD response but for a JSON string. I want to know if there are possible data elements that are not listed Yodlee's JSON response examples.
The only info I can really find so far is here.
When I review these examples, it appears that the example JSON responses do not fully describe every field.
Here is part of the getItemSummaryForItem1 JSON example for maturityDate element
"maturityDate":{
},
It looks like there is an array, but the possible data elements for that maturityDate array are undeclared. Then later on maturityDate is shown to be:
"maturityDate":{
"date":"0014-02-01T00:00:00-0800",
"localFormat":"dd/MM/yyyy"
},
And then in another example from getUserTransactionCategories
{
"categoryId":31,
"categoryName":"Retirement Income",
"transactionCategoryTypeId":2,
"isBudgetable":1,
"localizedCategoryName":"Retirement Income",
"isHidden":false,
"categoryLevelId":3
},
Based on that I would think all possible data elements are there.
But then there is another one which introduces the childCategory data element
{
"categoryId":2,
"categoryName":"Automotive Expenses",
"isDeleted":0,
"transactionCategoryTypeId":4,
"isBudgetable":1,
"localizedCategoryName":"Automotive Expenses",
"isHidden":false,
"categoryLevelId":3,
"childCategory":[
{
"categoryId":5641,
"categoryName":"1_SubCategory1",
"categoryDescription":"Subcategory desc1",
"isDeleted":0,
"isBudgetable":0,
"localizedCategoryName":"1_SubCategory1",
"isHidden":false,
"parentCategoryId":2,
"categoryLevelId":4
}
}
Thanks!
Yodlee team is working on to get this details documented, this is a time taking process and will be soon available over their portal. Meanwhile, is there any specific field or API response for which you are looking to get all the child elements which will help you out without blocking your integration?
