In my application I need to use dynamic fields of a class.
The object is persisted into MongoDB (also dynamically) from json request:
Object obj = new Object()
def objectData = request.JSON.object
for(item in objectData) {
obj[item.key] = item.value
}
obj.save(flush: true)
However, when I am trying to get the objct back from Mongo, this way:
List<Object> objects = Object.list()
def objList = new ArrayList();
def filtered = ['class', 'active', 'metaClass', 'version']
for(obj in objects) {
objList.add(obj.properties)
}
I am getting something like this:
"objects" : [
{
"dbo" : {
"_id" : "531afe54300426462e60c1ce",
"key2" : "val2",
"key3" : "hello",
"version" : 1,
"key1" : "val1"
}
},
...
Of coarse I can take only the "dbo" of every object, and filter what I don't need manually, but it looks wrong. What would be the right way to get all the properties of an object including dynamic ones?
Definition of Object class:
package com.iibs.mongo
class Object {
String id
static mapWith = "mongo"
static constraints = {
}
}
Thanks,

Here is the group operation that I want to create depending on a nomenclature object.
private static GroupOperation createStatsGroupOperationFromNomenclature(Nomenclature nomenclature) {
Fields groupFields = Fields.fields("departmentCode");
nomenclature.getDepartmentCode().ifPresent(code -> groupFields.and("subDepartmentCode"));
nomenclature.getSubDepartmentCode().ifPresent(code -> groupFields.and("categoryCode"));
nomenclature.getCategoryCode().ifPresent(code -> groupFields.and("subCategoryCode"));
return group(groupFields)
.count().as("nbProducts")
.sum("$proposedMatchesAmount").as("nbProposedMatches")
.sum("$reviewedMatchesAmount").as("nbReviewedMatches");
}
With the previous function if I provide a departmentCode and a subDepartmentCode inside the nomenclature parameter, here is the mongo query that is executed :
{
_id: {
"departmentCode": "$departmentCode",
"subDepartmentCode": "$subDepartmentCode"
},
"nbProduct": {
$sum: 1
},
"proposedMatchesAmount": {
$sum: "$proposedMatchesAmount"
},
"reviewedMatchesAmount": {
$sum: "$reviewedMatchesAmount"
}
}
The result of this query are parsed in the following object :
#Builder
#Value
public class ProductsStatsDocument {
#Id
Nomenclature nomenclature;
Integer nbProducts;
Integer nbProposedMatches;
Integer nbReviewedMatches;
}
Problems append when I provide only a departmentCode inside the nomenclature parameter. Then the builded group operation has the following mongo query language equivalent:
{
_id: "$departmentCode",
"nbProduct": {
$sum: 1
},
"proposedMatchesAmount": {
$sum: "$proposedMatchesAmount"
},
"reviewedMatchesAmount": {
$sum: "$reviewedMatchesAmount"
}
}
And the result of this query couldn't be parsed to the previous ProductsStatsDocument because the result _id field id now a String and not a Nomenclature object.
Is it possible to force the group method to use an object as result _id field even with only one field ? Or is there an other way to build such a mongo group operation ?
=================================================================
Found the "why" of this issue. Here is a piece of code from spring data that transform the GroupOperation into a bson object :
} else if (this.idFields.exposesSingleNonSyntheticFieldOnly()) {
FieldReference reference = context.getReference((Field)this.idFields.iterator().next());
operationObject.put("_id", reference.toString());
} else {
And here is the exposesSingleNonSyntheticFieldOnly method :
boolean exposesSingleNonSyntheticFieldOnly() {
return this.originalFields.size() == 1;
}
As you can see, as soon as there is only one field to group on, it's used as _id result value.
So finally the solution that seems to works for now is to create a custom AggregationOperation that manage the document transformation _id part :
public class ProductsStatsGroupOperation implements AggregationOperation {
private static GroupOperation getBaseGroupOperation() {
return group()
.count().as("nbProducts")
.sum("$proposedMatchesAmount").as("nbProposedMatches")
.sum("$reviewedMatchesAmount").as("nbReviewedMatches");
}
private final Nomenclature nomenclature;
public ProductsStatsGroupOperation(Nomenclature nomenclature) {
this.nomenclature = nomenclature;
}
#Override
public Document toDocument(AggregationOperationContext context) {
Document groupOperation = getBaseGroupOperation().toDocument(context);
Document operationId = new Document();
for (Field field : getFieldsToGroupOn()) {
FieldReference reference = context.getReference(field);
operationId.put(field.getName(), reference.toString());
}
((Document)groupOperation.get("$group")).put("_id", operationId);
return groupOperation;
}
private Fields getFieldsToGroupOn() {
Fields groupFields = Fields.fields("departmentCode");
if (nomenclature.getDepartmentCode().isPresent()) {
groupFields = groupFields.and("subDepartmentCode");
}
if (nomenclature.getSubDepartmentCode().isPresent()) {
groupFields = groupFields.and("categoryCode");
}
if (nomenclature.getCategoryCode().isPresent()) {
groupFields = groupFields.and("subCategoryCode");
}
return groupFields;
}
}
There is a bad thing about this solution: the overrided method toDocument seems to be deprecated.
SQL query=>
where and ((subtype="dailyMessage" and registDate="today") or(subtype !="dailyMessage"))
i want to retrive this query by using mongodb.
i have this collection. (today is '2017-08-16T15:48:19.947Z')
{
"_id" : ObjectId("597768443b1fd6308c0350c0"),
"type" : "message",
"subtype" : "dailyMessage",
"message" : test1",
"registDate" : ISODate("2017-08-16T15:48:19.947Z")
},
{
"_id" : ObjectId("597768443b1fd6308c0350c1"),
"type" : "message",
"subtype" : "dailyPush",
"message" : test2",
"registDate" : ISODate("2017-07-25T15:48:19.947Z")
},
{
"_id" : ObjectId("597768443b1fd6308c0350c2"),
"type" : "message",
"subtype" : "dailyPush",
"message" : test3",
"registDate" : ISODate("2017-07-24T15:48:19.947Z")
}
here is my code(spring boot mongodb , using java 8)
List<String> listOfmessage = new ArrayList<String>();
listOfSubtype.add("dailyMessage");
criteria = Criteria.where("test").is("james");
criteria.andOperator(Criteria.where("registDate").gte(LocalDateTime.of(LocalDate.now(), LocalTime.MIDNIGHT)).lte(LocalDateTime.now()) , Criteria.where("subtype").in(listOfmessage) .orOperator(Criteria.where("subtype").nin(listOfmessage)));
my problem is that how can i insert orOperator on the andOperator?
As mentioned in the comment, the and outside the whole condition doesn't make sense. The below code is written for the following condition.
(condition1 AND condition2) OR condition3
Code:-
You may need to alter the below code to get the MongoOperations object based on your Spring configuration.
"register" is the collection name. You can change it accordingly as per your collection name.
public Boolean getRegisterData() {
MongoOperations mongoOperations = getMongoConnection();
List<String> listOfSubType = new ArrayList<String>();
listOfSubType.add("dailyMessage");
List<String> listOfMessage = new ArrayList<String>();
listOfMessage.add("test1");
Criteria criteriaSubTypeAndDate = new Criteria();
criteriaSubTypeAndDate.andOperator(Criteria.where("registDate")
.gte(LocalDateTime.of(LocalDate.now(), LocalTime.MIDNIGHT)).lte(LocalDateTime.now()),
Criteria.where("subtype").in(listOfSubType));
Criteria criteriaSubType = Criteria.where("subtype").ne("dailyMessage");
Criteria criteriaFull = new Criteria();
criteriaFull.orOperator(criteriaSubTypeAndDate, criteriaSubType);
Query query = new Query();
query.addCriteria(criteriaFull);
System.out.println(query);
mongoOperations.executeQuery(query, "register", new RegistryDocumentCallbackHandler());
return true;
}
Result set document processing class:-
processDocument() method will get executed for each document in the result set.
public class RegistryDocumentCallbackHandler implements DocumentCallbackHandler {
#Override
public void processDocument(DBObject dbObject) throws MongoException, DataAccessException {
System.out.println("Registry collections data ===>" + dbObject.toString());
}
}
Im working with a custom plugin for CRM online 2015 and every time I try to access the activityparty from the field "Email.To" I get
"base {System.SystemException} = {"Unable to cast object of type 'Microsoft.Xrm.Sdk.Entity' to type ...ActivityParty'."}"
Here is how my code looks like:
public class PreCreate : Plugin
{
public PreCreate()
: base(typeof(PreCreate))
{
base.RegisteredEvents.Add(new Tuple<int, string, string, Action<LocalPluginContext>>(20, "Create", "email", new Action<LocalPluginContext>(ExecutePreEntityCreate)));
}
public void ExecutePreEntityCreate(LocalPluginContext localContext)
{
var target = (Entity)localContext.PluginExecutionContext.InputParameters["Target"];
using (var context = new XrmServiceContext(localContext.OrganizationService))
{
var email = target.ToEntity<Email>(); //The entity has the right values
var activityPartyList=email.To // here I see the exception
//If I use the following code:
var activityParty = email.GetAttributeValue<EntityCollection>("to");
//I get an empty ActivityParty(empty Id)
}
}
}
Do I have to do some initialization for activityparty types?
There is no issue with the code, the field Email.To will return a EntityCollection and to obtain that you need to use:
var entityCollection = email.GetAttributeValue<EntityCollection>("to");
This will give you a collection of entities that need to be converted to ActivityParty(entityCollection.Entities).
To convert the Entities you need to:
foreach (var entityItem in entityCollection.Entities)
{
var ap = entityItem.ToEntity<ActivityParty>();
//Here you will get the LogicalName in this case Lead
// the Id and the name
var leadId = ap.PartyId.Id;
//To get the Lead
var lead=context.LeadSet.FirstOrDefault(l => l.Id == leadId);
}
I am trying to follow the guidelines provided http://msdn.microsoft.com/en-us/library/dn314429.aspx by Microsoft for Unittesting DbSets. All was going well - as they documented. Until I got to some code which works with a inheritance table. Since OfType() is an extension method, I cannot figure out how to create a Mock which will work to keep my code testable.
To clarify: I am trying to Test My Service Layer, which take a DBContext which is Injected, and which exposes several DbSets. In particular, I have an abstract History class, which has concrete derived types of StaffHistory, ContactHistory, etc. As a result, I only have 1 DbSet on my Dbcontext, which is of type History. I then use the Extension method OfType to set the discriminator and query the particular type.
When I create a Mock DbSet all usually works fine, except the OfType extension method fails, reporting NullReference Exception.
Any ideas or tips?
Service Layer:
public IEnumerable<ContactHistory> GetContactHistory(int ContactId, int AgeInDays)
{
var age = DateTimeOffset.Now.AddDays(-Math.Abs(AgeInDays));
return context.History.OfType<ContactHistory>()
.Where(h => h.ContactId == ContactId && h.CreatedAt >= age)
.AsEnumerable();
}
Unit Test Code:
[TestMethod]
public void History_Returns_Limited_Results()
{
var testData = new List<ContactHistory> {
new ContactHistory {
ContactId = 1,
CreatedAt = DateTimeOffset.Now,
UserName = "UserA",
Action = "Action",
},
new ContactHistory {
ContactId = 4,
CreatedAt = DateTimeOffset.Now.AddDays(-61),
UserName = "UserA",
Action = "Action",
},
new ContactHistory {
ContactId = 4,
CreatedAt = DateTimeOffset.Now.AddDays(-60),
UserName = "UserA",
Action = "Action",
},
new ContactHistory {
ContactId = 4,
CreatedAt = DateTimeOffset.Now,
UserName = "UserA",
Action = "Action",
}
}.AsQueryable();
// Setup
var mockContext = new Mock<IPEContext>();
var mockSet = new Mock<IDbSet<History>>();
mockSet.As<IQueryable<ContactHistory>>().Setup(m => m.Provider).Returns(testData.Provider);
mockSet.As<IQueryable<ContactHistory>>().Setup(m => m.Expression).Returns(testData.Expression);
mockSet.As<IQueryable<ContactHistory>>().Setup(m => m.ElementType).Returns(testData.ElementType);
mockSet.As<IQueryable<ContactHistory>>().Setup(m => m.GetEnumerator()).Returns(testData.GetEnumerator());
mockContext.Setup(c => c.History).Returns(mockSet.Object);
// Test
var service = new HistoryService(mockContext.Object);
var historyFound = service.GetContactHistory(4, 60);
// Verify
Assert.IsNotNull(historyFound);
Assert.AreEqual(2, historyFound.Count());
}
Is there something flawed in my approach? Is there something flawed in how I have setup my mock? This was following the Microsoft Article I mentioned above so that I could test service logic acting on a DbSet. The only flaw seems to be the Extension Method - not sure how I should work around that.
OK - I have figured this out. Of course there was a simple answer, but one which eluded me, because I had already mapped the Linq Provider and all in as the Type IQueryable. If you are using the .OfType() method, your mock must return on the Untyped Queryable method.
Here is the test code to allow the Method to work properly:
[TestMethod]
public void History_Returns_Limited_Results()
{
var today = new DateTimeOffset(DateTime.Today, DateTimeOffset.Now.Offset);
var testData = new List<ContactHistory> {
new ContactHistory {
ContactId = 1,
CreatedAt = today,
UserName = "UserA",
Action = "Action",
},
new ContactHistory {
ContactId = 4,
CreatedAt = today.AddDays(-61),
UserName = "UserA",
Action = "Action",
},
new ContactHistory {
ContactId = 4,
CreatedAt = today.AddDays(-60),
UserName = "UserA",
Action = "Action",
},
new ContactHistory {
ContactId = 4,
CreatedAt = today,
UserName = "UserA",
Action = "Action",
}
}.AsQueryable();
// Setup
var mockContext = new Mock<IPEContext>();
var mockSet = new Mock<IDbSet<History>>();
mockSet.As<IQueryable>().Setup(m => m.Provider).Returns(testData.Provider);
mockSet.As<IQueryable>().Setup(m => m.Expression).Returns(testData.Expression);
mockSet.As<IQueryable>().Setup(m => m.ElementType).Returns(testData.ElementType);
mockSet.As<IQueryable>().Setup(m => m.GetEnumerator()).Returns(testData.GetEnumerator());
mockContext.Setup(c => c.History).Returns(mockSet.Object);
// Test
var service = new HistoryService(mockContext.Object);
var contact = new Person { ContactId = 4 };
var historyFound = service.GetContactHistory(contact, 60);
// Verify
Assert.IsNotNull(historyFound);
Assert.AreEqual(2, historyFound.Count());
}
I have 2 domain classes, User and Dog (for example)
class User {
String id
Map<String, Dog> dogs
}
class Dog {
String name
}
My Controller get as an input a json
{"key" : "dogKey", "userId" : "someId", "dogName" : "dog"}
def addDog(){
String key = request.JSON.key
User user = User.get(request.JSON.userId)
String dogName = request.JSON.dog
...
if(! user.dogs){
user.dogs = new HashMap<>(1)
}
user.dogs.put(key, new Dog(name: dogName))
user.save(flush: true)
}
after running the user data # Mongo is:
user:
{ _id:....,
dogs: {
"dogKey": null
}...
}
can someone please explain me what i'm missing?
Thanks!
Roy
may be dog reference is not save in database
def addDog(){
String key = request.JSON.key
User user = User.get(request.JSON.userId)
String dogName = request.JSON.dog
...
if(! user.dogs){
user.dogs = new HashMap<>(1)
}
Dog dog = new Dog(name: dogName)
dog.save(flush:true)
user.dogs.put(key, dog)
user.save(flush: true)
}
