I am using zf-boilerplate for my zend framework project. I am using the Gedmo extensions and need to get an instance of the doctrine event manager in the bootstrap.
ie. I would like to be able to do the following:
$evm = $this->getDoctrine()->getEventManager()
How can I do this?
You can access the entity manager by calling
Zend_Registry::get('em');
If you're in the middle of bootsrap, then make sure you bootstrap entity manager before accessing it.
Just like resource methods, you use the bootstrap() method to execute resource plugins. Just like with resource methods, you can specify either a single resource plugin, multiple plugins (via an array), or all plugins. Additionally, you can mix and match to execute resource methods as well.
(Zend Framework manual)
i.e. execute the code below first
// Execute all resource methods and plugins:
$bootstrap->bootstrap('doctrine');
UPDATE
Didn't notice the question was about EventManager. Use the code below in order to get access to it
Zend_Registry::get('doctrine')->getEventManager ();

The question may sound funny but I think this should be possible.
What I want is to use a repository that is purely custom but is exposed just like a Repository. This service would have methods to get, save, delete and list objects where the data could be from any arbitrary source.
Looking through the code, I think it should be possible since methods are accessed using CrudMethods and RepositoryInvoker. I belief this requires an implementation of RepositoryFactoryInformation that will be discovered by Repositories. I started experimenting a bit and it looks like a full-blown spring-data-noop module.
Am I on the right track or is there an easier way to accomplish this?
I've ended up writing spring-data-custom to create fully customized spring-data repositories, allowing custom code to be used with spring-data-rest etc.
Enable custom repositories (#EnableCustomRepositories)
Annotate eligible entities (#Custom)
Create a repository (extend CustomRepository<T, ID>)
Add custom behavior:
Let repository extend a new interface with the Custom suffix
Create an implementation of the new interface with the Impl prefix
Add one or more CRUD methods named findOne, save, findAll, delete (see DefaultCrudMethods)
Add query methods annotated with #Query
Export repository using spring-data-rest
(copied from README)
As #wwadge correctly mentioned, spring-data-keyvalue is an alternative. Repositories have to implement KeyValueAdapter, e.g. MapKeyValueAdapter.
The easier way is to use spring-data-keyvalue project which does what you are trying to do.
I try to create the entity like this:
DatastoreService ds = DatastoreServiceFactory.getDatastoreService();
Entity stock = new Entity("Stock", 1);
stock.setProperty("Stock", "FCB");
ds.put(stock);
but keep getting the error:
No source code is available for type com.google.appengine.api.datastore.DatastoreService; did you forget to inherit a required module?
The error means just what it says, the GWT compiler needs access to the Java source it compiles to Javascript, and obviously DatastoreService is not something that should exist on the frontend - so you have an architecture issue here.
You'll need to write a proxy that can call a server component (Which in turns calls the DatastoreService) and returns DTOs/value objects (that you define and thus have the source for).
Cheers,
No source code is available
GWT transliterate Java to Javascript, reading it's source code and there a limited language support.
What you're trying to achieve is a Server only operation and you're adding this operation within the client code, which will run on a browser. Neither GAE allow this or GWT has the source of these classes nor capability to do so.
Solution
You need to create a request to your server that will access the DatastoreService , the return the output to the client code.
Below a example of a properly architect GWT web application:
Like Rails is there any way to add custom error message to validator?
Like:
if(this.password != this.passwordConfirmation){
this.errors.add('password', {rule: 'invalid'})
}
You can create custom validations on your models. Or create custom objects and inject them into your models to resusable code. Its actually in the docs!
http://sailsjs.org/#/documentation/concepts/ORM/Validations.html?q=custom-validation-rules
You can create a custom config file for error handling. You can reach that global config object by sails.config.error for example. Advantage of this solution is, that you can access this object in services and other places, where you have no access to the res object.
Next step would be creating a policy which would pass this config error object to res.locals. Or it could be handled in a response file, but I have no experience with that.
Out of the box, Sails.js does not support custom validation messages. But there's a workaround, using hooks.

I'm using ASP.Net MVC 4 RTM Web API. I have a controller action with a parameter that I'd like to populate via custom model binding. To achieve this, I created a class that derives from System.Web.Http.Controllers.HttpParameterBinding that sets the value of this parameter. I then created an attribute class that derives from System.Web.Http.ParameterBindingAttribute which I use to decorate the parameter on my controller action.
This is all working great, my HttpParameterBinding class is populating the action parameter correctly. The problem I have is that my custom parameter binding class has a dependency that I'd like resolved via my IoC container (Unity). Is there a way to override how Web API creates HttpParameterBinding instances so that I can build up my custom binding class dependency from Unity? I was able to do something similar for a filter attribute by creating a custom filter provider that uses Unity's BuildUp method to populate dependencies, however I'm not seeing anything similar for Web API's HttpParameterBindings.
In general: to use IoC / Unity in the Web API you need to set it up seperately.
Try downloading the nuget package Unity.WebApi and see if that helps!
Take a look at this article: Parameter Binding in WebAPI
It walks through a couple different options from Converters to Binders to BinderProviders. It sounds like you may be able to write a custom ModelBinderProvider which knows how to provide your dependency. If that isn't high enough in the chain you can look at replacing the default IActionValueBinder service. It's a DefaultActionValueBinder instance, which you can extend or simply re-implement.
I also highly recommend downloading the WebAPI source code, as it's been an incredible help for these issues as I've run into them. Here's the WebAPI source code. I recommend downloading it so you can open it in VS for easy navigation.
Feel free to check out FlitBit too (It's very modular, don't let the number of packages scare you off)! I'm working on a WebAPI package for supporting FlitBit, specifically FlitBit.IoC and FlitBit.Dto. I'll add an update if I work out my IoC issue, since it's very similar to yours.
I'm working on a GWT project and I find it very tedious to have to add a function to my servlet, then copy and paste the function signature into my Service interface, then copy and paste it into my ServiceAsync interface and change the return parameter to be a callback. Is there a tool or a setting where I can just add public methods to my class and they can get copied into the other interfaces? Even if its not automatic it would be nice to be able to select specific methods and have them copied automatically.
I'm using eclipse and ideally it would update my interface each time I save implementation since thats when it checks my code and complains that my changes break the interface.
If you add the method to your *Service interface, then Eclipse can auto-generate the method ("Add unimplemented methods...") in your *ServiceImpl servlet, which you can then just fill in. Also, if you've got the Google Eclipse plugin installed, it will underline the new method in your *Service interface and complain that it's not in the *ServiceAsync. It might have a CTRL + 1 option to generate it in that interface as well.
You don't really need a tool. Just factor out the many RPC methods by just one method that takes a Request/Response. all you need to do is create subclasses of Request/Response and you don't need to think about adding new methods in the 2 interfaces.
You can use Google Guice on the server side to map the incomming request to a class handling the call... or you could use a visitor approach to forward the incoming request to the code handling the request (without resorting on a big instanceof construct).
