http://localhost:8080/myApp/camunda-rest/engine/default/history/process-instance/count?processInstanceBusinessKey=myApp-201010
{
"count": 1
}
If I try to get from REST client it is providing me proper output(if the value exist in database). But I need to get the value from Java application using the below code,
ProcessInstanceRestService pIRS=new ProcessInstanceRestService("default");
ProcessInstanceQueryDto queryParameter=new ProcessInstanceQueryDto();
List<VariableQueryParameterDto> variables=new ArrayList<VariableQueryParameterDto>();
VariableQueryParameterDto variableQueryParameterDto = new VariableQueryParameterDto();
variableQueryParameterDto.setName("processInstanceBusinessKey");//processInstanceBusinessKey
variableQueryParameterDto.setValue("myApp-201010");
variables.add(variableQueryParameterDto);
queryParameter.setVariables(variables);
queryParameter.setParameter("myApp-201010");
CountResultDto cRD=pIRS.queryProcessInstancesCount(queryParameter);
return ""+cRD.getCount();
I am getting count as 0 everytime , Please let me know where I am going wrong
The business key is not a process variable. Also in the REST URL you query for historic process instances but in the code snipped you use the runtime process instance query. There are setter methods for the business key on both runtime (ProcessInstanceQueryDto#setBusinessKey) and history (HistoricProcessInstanceQueryDto#setProcessInstanceBusinessKey) DTOs.

I am trying to retrieve an entity immediately after it was saved. When debugging, I insert the entity, and check entities in google cloud console, I see it was created.
Key key = datastore.put(fullEntity)
After that, I continue with getting the entity with
datastore.get(key)
, but nothing is returned. How do I retrieve the saved entity within one request?
I've read this question Missing entities after insertion in Google Cloud DataStore
but I am only saving 1 entity, not tens of thousands like in that question
I am using Java 11 and google datastore (com.google.cloud.datastore. package)*
edit: added code how entity was created
public Key create.... {
// creating the entity inside a method
Transaction txn = this.datastore.newTransaction();
this.datastore = DatastoreOptions.getDefaultInstance().getService();
Builder<IncompleteKey> builder = newBuilder(entitykey);
setLongOrNull(builder, "price", purchase.getPrice());
setTimestampOrNull(builder, "validFrom", of(purchase.getValidFrom()));
setStringOrNull(builder, "invoiceNumber", purchase.getInvoiceNumber());
setBooleanOrNull(builder, "paidByCard", purchase.getPaidByCard());
newPurchase = entityToObject(this.datastore.put(builder.build()));
if (newPurchase != null && purchase.getItems() != null && purchase.getItems().size() > 0) {
for (Item item : purchase.getItems()) {
newPurchase.getItems().add(this.itemDao.save(item, newPurchase));
}
}
txn.commit();
return newPurchase.getKey();
}
after that, I am trying to retrieve the created entity
Key key = create(...);
Entity e = datastore.get(key)
I believe that there are a few issues with your code, but since we are unable to see the logic behind many of your methods, here comes my guess.
First of all, as you can see on the documentation, it's possible to save and retrieve an entity on the same code, so this is not a problem.
It seems like you are using a transaction which is right to perform multiple operations in a single action, but it doesn't seem like you are using it properly. This is because you only instantiate it and close it, but you don't put any operation on it. Furthermore, you are using this.datastore to save to the database, which completely neglects the transaction.
So you either save the object when it has all of its items already added or you create a transaction to save all the entities at once.
And I believe you should use the entityKey in order to fetch the added purchase afterwards, but don't mix it.
Also you are creating the Transaction object from this.datastore before instantiating the latter, but I assume this is a copy-paste error.
Since you're creating a transaction for this operation, the entity put should happen inside the transaction:
txn.put(builder.builder());
Also, the operations inside the loop where you add the purchase.getItems() to the newPurchase object should also be done in the context of the same transaction.
Let me know if this resolves the issue.
Cheers!
I need to intercept my loopback queries before they query my Mongodb to add additional filters, for example, to limit the object to what the user has access to.
I can successfully update the query on access operation hook to add filters to the GET /Applications , where Applications is my object. However This fails to work for GET /Applications/count
The command runs with a 200, however it returns zero results, even though I'm adding the exact same filters. There most be something different about count that I'm missing. The ctx object looks have a ton of functions/objects in it. I'm only touching the query property, but there must be something else I need to do.
Any ideas? Thank you, Dan
Could you please share your access hook observer's implementation. I tried it on a sample app, and following access hook works as expected for /api/Books/count:
module.exports = function(Book) {
Book.observe('access', function logQuery(ctx, next) {
ctx.query.where.id = 2; // changing filter value for where
console.log('Accessing %s matching %j', ctx.Model.modelName, ctx.query.where);
next();
});
};
Verify that you're modifying query property of Context (see access hook).
Hope that helps.
I'm new to OTRS (3.2) and also new to PERL but I have been given the task of setting up OTRS so that it will make a call to our remote webservice so a record can be created on our end when a ticket is set as "Closed".
I set up various dynamic fields so the customer service rep can fill in additional data that will be passed into the webservice call along with ticket details.
I couldn't get the webservice call to trigger when the ticket was "Closed" but I did get it to trigger when the "priority" was changed so I'm just using that now to test the webservice.
I'm just using the Test.pm and TestSimple.pm files that were included with OTRS.
When I look at the Debugger for the Webserice, I can see that the calls were being made:
$VAR1 = {
'TicketID' => '6'
};
My webservice currently just has one method "create" which just returns true for testing.
however I get the following from the Test.pm
"Got no TicketNumber (2014-09-02 09:20:42, error)"
and the following from the TestSimple.pm
"Error in SOAP call: 404 Not Found at /TARGET/SHARE/var/otrs/Kernel/GenericInterface/Transport/HTTP/SOAP.pm line 578 (2014-09-02 09:20:43, error)
I've spent countless hours on Google but couldn't find anything on this. All I could find is code for the Test.pm and TestSimple.pm but nothing really helpful to help me create a custom invoker for my needs and configure the webservice in OTRS to get it to work.
Does anyone have any sample invokers that I can look at to see how to set it up?
Basically I need to pass the ticket information along with my custom dynamic fields to my webservice. From there I can create the record on my end and do whatever processing.
I'm not sure how to setup the Invoker to pass the necessary ticket fields and dynamic fields and how to make it call a specific method in my remote webservice.
I guess getting the Test.pm and TestSimple.pm to work is the first step then I can modify those for my needs. I have not used PERL at all so any help is greatly appreciated.
I'm also struggling with similar set of requirements too. I've also never programmed in PERL, but I can tell you at least that the "Got no TicketNumber" in the Test.pm is right from the PrepareRequest method, there you can see this block of code:
# we need a TicketNumber
if ( !IsStringWithData( $Param{Data}->{TicketNumber} ) ) {
return $Self->{DebuggerObject}->Error( Summary => 'Got no TicketNumber' );
}
You should change all references to TicketNumber to TicketID, or remove the validation whatsoever (also there is mapping to ReturnedData variable).
Invoking specific methods on your WS interface is quite simple (but poorly documented). The Invoker name that you specify in the "OTRS as requester" section of web service configuration corresponds to the WS method that will be called. So if you have WS interface with a method called "create" just name the Invoker "create" too.
As far as the gathering of dynamic field goes, can't help you on that one yet, sorry.
Cheers
We are building some plugins in Microsoft Dynamics CRM by inheriting from IPlugin. We have these configured so they fire whenever an Account is updated.
The problem is the plugins are calling our services, which causes our service to respond with an update. We are doing some pretty hacky things right now to prevent these cyclical updates from happening.
We were wondering if there was a way to pass a value to the IOrganizationService service (the web service) that a plugin can look at. Our other system could send a flag ("hey, don't bothing sending an update!") and the plugin could skip calling back.
Can we pass parameters from web service to the plugins?
Good idea could be usage of custom flag-field. For example you add bit field and call it CallFromExternalSystem. So when you make an update from your external system through IOranizationService you just fill this flag with true field and in plugin you can check condition that this field is present in fields list so you have no need to call external system endpoint again.
We decided the correct solution was to use the value found in IPluginExecutionContext.InputParameters["Target"]. In the case of an Update, this returns an Entity containing attributes for all the attributes that were updated.
We basically have a list of attribute names we cared about. We loop through names and see if any of them appear in the entity attribute list. If so, we send an update to our other system. The good news is, Dynamics CRM ignores updates where the values don't actually change, so trying to update a value to itself is no-op.
public void Execute(IServiceProvider serviceProvider)
{
IPluginExecutionContext context = serviceProvider.GetService(typeof(IPluginExecutionContext));
Entity entity = (Entity)context.InputParameters["Target"];
string[] fields = new string[] { "name", "statecode", "address1_line1" };
bool hasUpdates = fields.Where(f => entity.Attributes.Contains(f)).Any();
if (!hasUpdates)
{
return;
}
}
I found a strange problem while doing some unit-testing on Magento.
I have a test function which test a value from core_config_data table. So in order to have access to that value for test, in the setUp() function I am saving the config value in database:
public function setUp()
{
parent::setUp();
$systemConfig = new Mage_Core_Model_Config();
$systemConfig->saveConfig(
'my/custom/path/config',
12
);
}
and in my test method I am getting that value from database likeso:
$productsNo = Mage::getStoreConfig(my/custom/path/config);
but its value is null, and not a string as expected.
This is strange, because if I am refreshing the database after running the test, the value it's existing in database. And if I'm running the test again, the test will work and the value it's not null anymore.
What am I doing wrong? I don't save the value correctly, or I don't fetch it in a good way?
You only save the configuration value to the database, but you don't refresh the config cache, which is used by Mage::getStoreConfig().
To achieve saving and refreshing at the same time you could use:
Mage::app()->getConfig()
->saveConfig('my/custom/path/config', 12)
->reinit();
This way the configuration value will be available in the current and subsequent requests.
In case you don't really need persistence, that is, if you only need this configuration value for the current request, than I'd rather recommend to use:
Mage:app()->getStore()
->setConfig('my/custom/path/config', 12);
