  • Why don't Domain class static methods work from inside a grails "service"?

    - by ?????
    I want a grails service to be able to access Domain static methods, for queries, etc. For example, in a controller, I can call IncomingCall.count() to get the number of records in table "IncomingCall" but if I try to do this from inside a service, I get the error: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'incomingStatusService': Invocation of init method failed; nested exception is groovy.lang.MissingMethodException: No signature of method: static ms.wdw.tropocontrol.IncomingCall.count() is applicable for argument types: () values: [] How do these methods get injected? There's no magic def statement in a controller that appears to do this. Or is the problem that Hibernate isn't available from my Service class?

  • Comparison of collection datatypes in C#

    - by Joel in Gö
    Does anyone know of a good overview of the different C# collection types? I am looking for something showing which basic operations such as Add, Remove, RemoveLast etc. are supported, and giving the relative performance. It would be particularly interesting for the various generic classes - and even better if it showed eg. if there is a difference in performance between a List<T> where T is a class and one where T is a struct. A start would be a nice cheat-sheet for the abstract data structures, comparing Linked Lists, Hash Tables etc. etc. Thanks!

  • Configuring Warden for use in RSpec controller specs

    - by Chris Peters
    I was able to use Devise's sign_in method to log in a user in my controller specs. But now that I'm removing Devise from my application, I'm not quite sure how to get similar functionality working with just Warden on its own. How should I go about setting up spec/spec_helper.rb and related spec/support/*.rb files to get Warden running within controller specs sufficiently? I've tried setting up a file at spec/support/warden.rb with these contents: RSpec.configure do |config| config.include Warden::Test::Helpers config.after do Warden.test_reset! end end Then I have before calls similar to this to authenticate a user factory: before { login_as FactoryGirl.create(:user) } But here is the error that I keep seeing: NameError: undefined method `user' for nil:NilClass This error traces back to my authenticate_user! method in the controller: def authenticate_user! redirect_to login_path, notice: "You need to sign in or sign up before continuing." if env['warden'].user.nil? end I'd appreciate any guidance that anyone could provide.

  • Strange Exchange 2010 Mailbox issues

    - by jmreicha
    A little bit of information on my environment. I have 2 Exchange 2010 mailbox servers setup in a DAG, connected to a VNX SAN via fiber for the mailbox database disks. One of the servers seems to be working fine as it isn't throwing any similar errors but the other has been receiving strange errors in Event Viewer. I haven't been able to find a pattern to when these happen and I'm not really sure what I should be looking at to troubleshoot this. At this point I am wondering if the issue resides on the SAN or if this is because of an improper shutdown or something else on the Exchange side of things? Here are a few of the errors if that helps:

  • Autofac: Reference from a SingleInstance'd type to a HttpRequestScoped

    - by Michael Wagner
    I've got an application where a shared object needs a reference to a per-request object. Shared: Engine | Per Req: IExtensions() | Request If i try to inject the IExtensions directly into the constructor of Engine, even as Lazy(Of IExtension), I get a "No scope matching [Request] is visible from the scope in which the instance was requested." exception when it tries to instantiate each IExtension. How can I create a HttpRequestScoped instance and then inject it into a shared instance? Would it be considered good practice to set it in the Request's factory (and therefore inject Engine into RequestFactory)?

  • Outlook Replies with Inline Comments

    - by BillN
    I have a user who uses Word as his e-mail editor. Often when replying to an e-mail, he'll insert his comments into the body of the original e-mail. Since he is using Word as the editor, these show as [User Name] Comment Text in a contrasting color. However, some users see the comments in their Outlook, and others do not. I've tried Selecting/DeSelecting Word as the e-mail editor on the recipients, and it does not seem to make a difference. We are using Exchange 2007 with Outlook 2003 and Outlook 2007 clients along with a few Entourage Clients. There does not seem to be a pattern related to which client is used, but Entourage seems to be more likely to have the problem. TIA, Bill

  • Remove binding to FrameworkElementFactory

    - by Damien
    I am currently creating a datatemplate to display data in a listview control in a specific manner and bound to the data. This works fine. But I need to be able to remove the bindings when the screen is closed and control is being disposed. How can I do this? I am thinking of just passing null as the second parameter of SetBinding and not sure if this will fix the issue. Also I have tried BindingOperation.ClearBindings, but I have a FrameworkElementFactory object and not a DependancyObject. Any help would be appricaited. //Create a Element Factory object to save the elements that make //up the DataTemplate cellTemplateFactory = new FrameworkElementFactory(typeof(TextBlock)); //Set the binding to the text property of the textblock element var binding = new Binding(dispColumn.BindingField) { TargetNullValue = string.Empty, Mode = BindingMode.OneTime };

  • advantages of Zend_Db_Table vs raw (My)SQL?

    - by sunwukung
    Currently working on a new Zend application and developing the Model. Having worked with Zend_Db_Table before, I opted to replace references in the Model to the Table API with a custom SQL script to take care of data access duties. Now I'm looking at developing a new application/domain model, and I wanted to get some feedback from people re: their experiences with Zend_Db API vs raw SQL, and use cases where it would be preferable to use the API. From a project perspective, the DB platform is unlikely to change from MySQL - so it doesn't need to be particularly abstract - and I assume writing a custom SQL API will be more performant than the assorted classes the Zend DB API requires.

  • Looking for a syntactic shortcut for accessing dictionaries

    - by Sisiutl
    I have an abstract base class that holds a Dictionary. I'd like inherited classes to be able to access the dictionary fields using a convenient syntax. Currently I have lots of code like this: string temp; int val; if (this.Fields.TryGetValue("Key", out temp)) { if (int.TryParse(temp, out val)) { // do something with val... } } Obviously I can wrap this in utility functions but I'd like to have a cool, convenient syntax for accessing the dictionary fields where I can simply say something like: int result = @Key; Is there any way to do something like this in C# (3.5)?

  • Make a usable Join relationship with LINQ on top of a database CSV design error

    - by jdk
    I'm looking for a way to fix and/or abstract away a comma-separated values (CSV) list in a database field in order to reconstruct a usable relationship such that I can properly join the two tables below and query them using LINQ and its Join method. Following is a sample showing the Person table and CsvArticleIds field having a CSV value to represent a one-to-many association with Article records. TABLE [dbo].[Person] Id Name CsvArticleIds -- ---------- -------- 1 Joe "15,22" 5 Ed "22" 10 Arnie "8,15,22" ^^^(Of course a link table should have been created; nonetheless the relationship with articles is trapped inside that list of CSV values.) TABLE [dbo].[Article] Id Title -- ---------- 8 Beginning C# 15 A Historic look at Programming in the 90s 22 Gardening in January Additional Info the fix can be at any level: C#.NET or SQL Server something easy because I will be repeating the solution for many other CSV values in other tables. Elegant is nice too. not looking for efficiency because this is part of a one-time data migration task and can take as long as it wants to run.

This is weird.

  • creative way for implementing Data object with its corresponding business logic class in java

    - by ekeren
    I have a class that need to be serialized (for both persistentcy and client-server communication) for simplicity's sake let's call the classes Business a BusinessData and I prefix for their Interfaces. All the getter and setter are delegated from Business class to BusinessData class. I thought about implementing IBusinessData interface that will contain all the getter and setters and IBusiness interface that will extend it. I can either make Business extend BuisnessData so I will not need to implement all getter and setter delegates, or make some abstract class ForwardingBusinessData that will only delegate getter and setters. Any of the above option I lose my hierarchy freedom, do any of you have any creative solutions for this problem... I also reviewed DAO pattern: http://java.sun.com/blueprints/patterns/DAO.html

  • Adding business logic to a domain class using a getter style method name

    - by Richard Paul
    I'm attempting to add a method to a grails domain class, e.g. class Item { String name String getReversedName() { name.reverse() } } When I attempt to load the application using grails console I get the following error: Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory':Invocation of init method failed; nested exception is org.hibernate.PropertyNotFoundException: Could not find a setter for property reversedName in class Item ... 18 more It looks like Hibernate is interpreting getReversedName() as a getter for a property, however in this case it is a derived field and hence should not be persisted. Obviously in my actual code the business logic I'm exposing is more complex but it isn't relevant to this question. I want to be able to call item.reversedName in my code/gsps. How can I provide property (getter) access to a method in a Grails domain class without Grails attempting to map it with Hibernate?

  • OOP App Architecture: Which layer does a lazy loader sit in?

    - by JW
    I am planning the implemention an Inheritance Mapper pattern for an application component http://martinfowler.com/eaaCatalog/inheritanceMappers.html One feature it needs to have is for a domain object to reference a large list of aggreageted items (10,000 other domain objects) So I need some kind of lazy loading collection to be passed out of the aggregate root domain object to other domain objects. To keep my (php) model scripts organised i am storing them in two folders: MyComponent\ controllers\ models\ domain\ <- domain objects, DDD repository, DDD factory daccess\ <- PoEAA data mappers, SQL queries etc views\ But now I am racking my brains wondering where my lazy loading collection sits. Any suggestions / justifications for putting it in one place over another another?

  • what is wrong: "value Parsers is not a member of package scala.util.parsing.combinator"?

    - by Nick Fortescue
    I've got the above odd error message that I don't understand "value Parsers is not a member of package scala.util.parsing.combinator". I'm trying to learn Parser combinators by writing a C parser step by step. I started at token, so I have the classes: import util.parsing.combinator.JavaTokenParsers object CeeParser extends JavaTokenParsers { def token: Parser[CeeExpr] = ident } abstract class CeeExpr case class Token(name: String) extends CeeExpr This is as simple as I could make it. The code below works fine, but if I uncomment the commented line I get the error message given above: object Play { def main(args: Array[String]) { //val parser: _root_.scala.util.parsing.combinator.Parsers.Parser[CeeExpr] CeeParser.token val x = CeeParser.token print(x) } } In case it is a problem with my setup, I'm using scala 2.7.6 via the scala-plugin for intellij. Can anyone shed any light on this? The message is wrong, Parsers is a member of scala.util.parsing.combinator.

  • .NET: Best way to execute a lambda on UI thread after a delay?

I thought of several ways to do this and finally settled on this approach Task.Factory.StartNew(() => Thread.Sleep(1000)) .ContinueWith((t) => textBlock.Text="Done",TaskScheduler.FromCurrentSynchronizationContext()); But I'm wondering if there's an easier way that I missed. Any suggestions for a shorter, simpler or easier technique? Assume .NET 4 is available.

  • Designing constructors around type erasure in Java

    - by Internet Friend
    Yesterday, I was designing a Java class which I wanted to be initalized with Lists of various generic types: TheClass(List<String> list) { ... } TheClass(List<OtherType> list) { ... } This will not compile, as the constructors have the same erasure. I just went with factory methods differentiated by their names instead: public static TheClass createWithStrings(List<String> list) public static TheClass createWithOtherTypes(List<OtherType> list) This is less than optimal, as there isn't a single obvious location where all the different options for creating instances are available. I tried to search for better design ideas, but found surprisingly few results. What other patterns exist for designing around this problem?

  • Why does CentOS Linux use cpu/core #1 so much more in a 4-core system?

    - by ck_
    I've been watching top and htop for awhile on a very active server and I am wondering why linux does not automatically use cpu affinity better? CPU #1 (actually core #1 of 4) is used much more heavily than the others. Is there a setting similar to what vm.swappiness does for vm swap that forces a preferred affinity pattern? Should I be using forced affinity settings within mysql/apache/nginx/exim to get better results? This is on CentOS 2.6.32-279 x86_64 SMP Thanks for any suggestions.
