I'm trying to use in memory test with NHibernate, and i succeeded to do that in this little project :
https://github.com/demojag/NHibernateInMemoryTest
As you can see from the map of the object i had to comment this line :
//SchemaAction.None(); Test will fail. this option hide the schema exportation.
this comment is just i guess I've made because so far i haven't found serious documentation about Schema Actions.
I'm doing those tests because i have an existing situation i would like to test in memory but all the entity maps have the option SchemaActions.None(), and when i try to execute the in memory test i get a lot of "no such tables".
I would like to know if exist a way to keep the Schema action option set to none and export the schema anyway ? (i know that can be an encapsulation violation so it would not really have a lot of sense).
I would like to leave this option set to none because is a "DatabaseFirst" application , and i can't take the risk to drop the database and re create it every time the configuration is build, but i guess, if in the configuration i don't specify the instruction "exposeConfiguration" and SchemaExport, i can be pretty safe.
Thank you in advice
Giuseppe.
You should be able to override any and all settings in the HBM or Fluent NHibernate mappings via the NHibernate.Cfg.Configuration.BeforeBindMapping event which gives you programmatic runtime access to NHibernate's internal model for a mapping. See the example below which sets up BeforeBindMapping event handler which overrides the SchemaAction specified in the mapping to whatever you want.
public NHibernate.Cfg.Configuration BuildConfiguration()
{
var configuration = new NHibernate.Cfg.Configuration();
configuration.BeforeBindMapping += OnBeforeBindMapping;
// A bunch of other stuff...
return configuration;
}
private void OnBeforeBindMapping( object sender, NHibernate.Cfg.BindMappingEventArgs bindMappingEventArgs )
{
// Set all mappings to use the fully qualified namespace to avoid class name collision
bindMappingEventArgs.Mapping.autoimport = false;
// Override the schema action to all
foreach ( var item in bindMappingEventArgs.Mapping.Items )
{
var hbmClass = item as NHibernate.Cfg.MappingSchema.HbmClass;
if ( hbmClass != null )
{
hbmClass.schemaaction = "all";
}
}
}

We have some logic that depends on the record type of a custom object in our managed package. One of our clients has created some custom record types for this SObject - which is throwing an exception.
We've put in a fix, but want to update our unit tests to catch this case as well - so we need to be able to create a new RecordType for this SObject and assign it. However, I cannot figure out how to do this dynamically in Apex.
Tried:
insert new RecordType(...);
This throws "DML not allowed on RecordType".
According to SF API the RecordType has a "create" method, but:
RecordType rt = new RecordType();
rt.DeveloperName = 'Test';
rt.Name = 'Test';
rt.SObjectType = 'Listing__c';
rt.create();
Yields "Method does not exist or incorrect signature". Same result when trying as a static method:
RecordType.create(rt);
Ideas?
After discussing with some other SF devs and re-reading the API documentation, it looks like this cannot be done through APEX API (though possible through SOAP API calls).

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;
}
}
For my Flash Builder 4.6 Project I have a http service defined which looks at a url from our website.
What I'd like to be able to do though is to change the web service url on the fly within the app. i.e. using the existing url as default but having an admin/settings screen to change where the web service points (either stored in our sqlite database or in local memory).
This would be so that we could allow our customers to host their own version of the website/database but still be able to use/download the app through the app stores.
Has anyone had any experience with doing this?
EDIT: Adding some more details after the comments below.
When I created the HTTP Service through the FlashBuilder wizard it creates two web service classes a super class and a sub class which inherits from the super class. All of the code that the wizard populates goes into the super class.
I can assume that the code I need to put in would be in the sub class. But I do not know which function I'd put it in or how.
Below is a sample of the Super's constructor:
// initialize service control
_serviceControl = new mx.rpc.http.HTTPMultiService("websitehere");
var operations:Array = new Array();
var operation:mx.rpc.http.Operation;
var argsArray:Array;
operation = new mx.rpc.http.Operation(null, "loginRequest");
operation.url = "login.php";
operation.method = "GET";
argsArray = new Array("un","pw");
operation.argumentNames = argsArray;
operation.serializationFilter = serializer0;
operation.properties = new Object();
operation.properties["xPath"] = "/";
operation.contentType = "application/x-www-form-urlencoded";
operation.resultType = valueObjects.Data;
operations.push(operation);
_serviceControl.operationList = operations;
I'm not sure what property of the _serviceControl variable I would need to alter.
Also when I search for my website in my code it brings back a .fml file inside a .model directory which seems to get auto refreshed if I change the service url through the wizard. Would this not cause an issue?
I then have the challenge of accessing the user defined url. Within the app we use an sqlite database to store data but I think it would probably be better to use a 'SharedObject' which we also use to know what account they are logged into. How reliable is this? I assume I would be able to access this via the Service?
Though the awkward thing is that we were planning to have this configurable on a settings screen that would have been accessed after logging in. But to log in it would already need to know which server to point to.
if im reading your question correctly then your main ambition is to dynamically change the url for the services based on a user defined variable.
This is very easy to accomplish and even easier to accomplish if you are using parsley / spicelib.
a few points
dont change the code in the super file, this will get overwritten whenever the service gets refreshed. change everything in its generated sub-Class.
Shared Objects are very good for small quantities of data but should never be used for massive datasets i.e storing a big arraycollection.
Anyway here is how i achieve this.
In the SubClass you can change the constructor function.
Here is how i change my urls based on a config variable but you can just as easily use a SharedObject instead.
public function SubClassConstructor(){
if(CONFIG::DOMAIN_IDENT == "development" || CONFIG::DOMAIN_IDENT == "dev" || CONFIG::DOMAIN_IDENT == "d"){
_serviceControl.endpoint = "http://yoururl1";
}
else if(CONFIG::DOMAIN_IDENT == "production" || CONFIG::DOMAIN_IDENT == "prod" || CONFIG::DOMAIN_IDENT == "p"){
_serviceControl.endpoint = "http://yoururl2";
}
}
Of course this isn't exactly what your looking for but its a working solution, of course you can use Bindings to a Global ApplicationModel or direct reference to the SharedObject i guess you already know how to use the SharedObject.
Ask if you need any further help or guidance.
As cghrmauritius' solution didn't quite work for me, I am posting up the final solution that did work in my situation.
public function subConstructor()
{
super();
_serviceControl.baseURL = "http://url1";
}
Obviously for my final solution I need to implement the shareobject as well but overriding the url was my main priority.
I am importing data into a new Symfony2 project using Doctrine2 ORM.
All new records should have an auto-generated primary key. However, for my import, I would like to preserve the existing primary keys.
I am using this as my Entity configuration:
type: entity
id:
id:
type: integer
generator: { strategy: AUTO }
I have also created a setter for the id field in my entity class.
However, when I persist and flush this entity to the database, the key I manually set is not preserved.
What is the best workaround or solution for this?
The following answer is not mine but OP's, which was posted in the question. I've moved it into this community wiki answer.
I stored a reference to the Connection object and used that to manually insert rows and update relations. This avoids the persister and identity generators altogether. It is also possible to use the Connection to wrap all of this work in a transaction.
Once you have executed the insert statements, you may then update the relations.
This is a good solution because it avoids any potential problems you may experience when swapping out your configuration on a live server.
In your init function:
// Get the Connection
$this->connection = $this->getContainer()->get('doctrine')->getEntityManager()->getConnection();
In your main body:
// Loop over my array of old data adding records
$this->connection->beginTransaction();
foreach(array_slice($records, 1) as $record)
{
$this->addRecord($records[0], $record);
}
try
{
$this->connection->commit();
}
catch(Exception $e)
{
$output->writeln($e->getMessage());
$this->connection->rollBack();
exit(1);
}
Create this function:
// Add a record to the database using Connection
protected function addRecord($columns, $oldRecord)
{
// Insert data into Record table
$record = array();
foreach($columns as $key => $column)
{
$record[$column] = $oldRecord[$key];
}
$record['id'] = $record['rkey'];
// Insert the data
$this->connection->insert('Record', $record);
}
You've likely already considered this, but my approach would be to set the generator strategy to 'none' for the import so you can manually import the existing id's in your client code. Then once the import is complete, change the generator strategy back to 'auto' to let the RDBMS take over from there. A conditional can determine whether the id setter is invoked. Good luck - let us know what you end up deciding to use.
In simple tests I can assert whether an object has been persisted by whether it's Id is no longer at it's default value. But delete an object and want to check whether the object and perhaps its children are really not in the database, the object Id's will still be at their saved values.
So I need to go to the db, and I would like a helper assertion to make the tests more readable, which is where the question comes in. I like the idea of using Load to save the db call, but I'm wondering if the ensuing exceptions can corrupt the session.
Below are how the two assertions would look, I think. Which would you use?
Cheers,
Berryl
Get
public static void AssertIsTransient<T>(this T instance, ISession session)
where T : Entity
{
if (instance.IsTransient()) return;
var found = session.Get<T>(instance.Id);
if (found != null) Assert.Fail(string.Format("{0} has persistent id '{1}'", instance, instance.Id));
}
Load
public static void AssertIsTransient<T>(this T instance, ISession session)
where T : Entity
{
if (instance.IsTransient()) return;
try
{
var found = session.Load<T>(instance.Id);
if (found != null) Assert.Fail(string.Format("{0} has persistent id '{1}'", instance, instance.Id));
}
catch (GenericADOException)
{
// nothing
}
catch (ObjectNotFoundException)
{
// nothing
}
}
edit
In either case I would be doing the fetch (Get or Load) in a new session, free of state from the session that did the save or delete.
I am trying to test cascade behavior, NOT to test NHib's ability to delete things, but maybe I am over thinking this one or there is a simpler way I haven't thought of.
Your code in the 'Load'-section will always hit Assert.Fail, but never throw an exception as Load<T> will return a proxy (with the Id-property set - or populated from the 1st level cache) without hitting the DB - ie. ISession.Load will only fail, if you access a property other than your Id-property on a deleted entity.
As for your 'Get'-section - I might be mistaken, but I think that if you delete an entity in a session - and later try to use .Get in the same session - you will get the one in 1st level cache - and again not return null.
See this post for the full explanation about .Load and .Get.
If you really need to see if it is in your DB - use a IStatelessSession - or launch a child-ISession (which will have an empty 1st level cache.
EDIT: I thought of a bigger problem - your entity will first be deleted when the transaction is committed (when the session is flushed per default) - so unless you manually flush your session (not recommended), you will still have it in your DB.
Hope this helps.
