Actions in WCF Data Services 5.0 RRS feed

  • Question

  • I am trying to use Actions in my WCF Data service

    I have followed the example form the WCF team blog but I am not able to see the action as a FunctionImport in the http://service/$metadata

    I have a method:

    [Action] public IEnumerable<ftInventory> CheckSupplies(ftSupplier supplier, int productId) {            return new List<ftInventory>();        }

    if I use the [WebGet] attribute then the function is seen in the metadata.

            public IEnumerable<ftInventory> CheckSupplies(ftSupplier supplier, int productId)
                return new List<ftInventory>();

    What do I need to do to ensure the the [Action]Attibute will also enable the function to show up in the metadata

  • Jawahar,

    Did you expose the action in the service's inInitializeService method?

    config.SetServiceActionAccessRule("*", ServiceActionRights.Invoke);

  • Yes I do have the setting as:

    config.SetServiceActionAccessRule("*", ServiceActionRights.Invoke);

  • Have you implemented an action provider as detailed the next parts of Alex's blog post? The article you wrote is a 3 part series on implementing actions.

  • Hello

    Yes I believe I have implemented the action provider, just took the code from the example in CodePlex and adapted for my use. I am not sure where the Action methods need to be defined. in the  SErvice class or the model class? or does it make a difference?

  • Hey Jawahar,

    On the IDataServiceActionProvider there is a method called CreateInvokable. What do you do there? The reason I ask is that this method is the place where you cooralate a method to actually be executed. I helped test this feature and the code that I wrote would look on the service for a method with the name that I was looking for via reflection, then in my implementation i would pass the MethodInfo and resolve the parameters that come into CreateInvokable and pass these into my implementation of IDataServiceInvokable. This invokable action would be called when SaveChanges is called then.

    My point is that this method needs to be implemented correctly for you to invoke the action that you need to. Perhaps we can review the code in this method along with a small samplet of your service code where you implement a method to see how this matches up. It seems like what you have has got to be pretty close.
