  • Get methods params type parsing wsdl file in a rails/ruby application

    - by Marco Sangiorgi
    Hi, I have a question about ruby and wsdl soap. I couldn't find a way to get each method's params and their type. For example, if I found out that a soap has a methods called "get_user_information" (using wsdlDriver) is there a way to know if this method requires some params and what type of params does it require (int, string, complex type, ecc..)? I'd like to be able to build html forms from a remote wsdl for each method... Sorry for my horrible English :D

  • What does :this means in Ruby on Rails?

    - by Marco
    Hi, I'm new to the Ruby and Ruby on Rails world. I've read some guides, but i've some trouble with the following syntax. I think that the usage of :condition syntax is used in Ruby to define a class attribute with some kind of accessor, like: class Sample attr_accessor :condition end that implicitly declares the getter and setter for the "condition" property. While i was looking at some Rails sample code, i found the following examples that i don't fully understand. For example: @post = Post.find(params[:id]) Why it's accessing the id attribute with this syntax, instead of: @post = Post.find(params[id]) Or, for example: @posts = Post.find(:all) Is :all a constant here? If not, what does this code really means? If yes, why the following is not used: @posts = Post.find(ALL) Thanks

  • Hibernate Unit tests - Reset schema

    - by Marco
    Hi, I'm testing the CRUD operations of my DAOs in JUnit tests. When i execute the single test, Hibernate always resets the schema and populates the DB in a known state. But when i execute multiple tests in a row, Hibernate resets the schema once, and then the data is accumulated during the execution of the tests. This is an unexpected behavior, so I'd like to add in the @Before method of the tests a function that explicitly resets the schema to avoid the pesistence of side data created by previous tests during the execution chain. Any tips? Thanks

  • jquery/javascripts not loading in ruby on rails

    - by Marco A
    I am having a very weird problem that just came up and my guess it's that it may be easy to solve, I just can't seem to figure out. in my layout/application.html.haml, I have the following: = javascript_include_tag :all Rather than RoR translating this to a lot of script-loading lines, it does the following: <script src="/beta/assets/all.js" type="text/javascript"></script> similarly, with defaults I get: <script src="/beta/assets/defaults.js" type="text/javascript"></script> What should I look for? or what I am missing? Thanks!

  • Overload and hide methods in Java

    - by Marco
    Hi, i have an abstract class BaseClass with a public insert() method: public abstract class BaseClass { public void insert(Object object) { // Do something } } which is extended by many other classes. For some of those classes, however, the insert() method must have additional parameters, so that they instead of overriding it I overload the method of the base class with the parameters required, for example: public class SampleClass extends BaseClass { public void insert(Object object, Long param){ // Do Something } } Now, if i instantiate the SampleClass class, i have two insert() methods: SampleClass sampleClass = new SampleClass(); sampleClass.insert(Object object); sampleClass.insert(Object object, Long param); what i'd like to do is to hide the insert() method defined in the base class, so that just the overload would be visible: SampleClass sampleClass = new SampleClass(); sampleClass.insert(Object object, Long param); Could this be done in OOP?

  • How to set a predefined value in a form in Rails

    - by marco
    So I just got started in Rails, and I'm trying to create an Object (a book_loan in my case) with a Form. The thing is that I get to this form by clicking on a book, so I pass the book_id as a parameter, like localhost:3000/loans/new?id=1. Now I don't want the user to be able to set the book id field in the form, since I already know the id. So my question is how to set the value in the form. I have been trying things like: <% form_for(@loan) do |f| %> <%= f.error_messages %> ... <%= @loan.book_id = params[:id] %> <%= f.submit 'Create' %> <% end %> without any success. Does anybody have a hint for me?

  • Apache crashes after installing mysqli

    - by Marco P.
    System: Apache 2.2 running on Windows 2008 Server with PHP 5.2.17 VC6 Thread-Safe as a Module and MySQL 5.5.17 - all working fine. After installing mysqli using the php package, Apache won't start anymore. There is no error message in the log. What I have tried: Make sure Windows PATH points to libmysql.dll: Yes, done. Make sure extension_dir points to the right point: Yes. Other extensions load fine. Try without mysqli: Yes, Apache loads fine then. Try without mysql: Yes, does not help. Test mysql itself: Restarts server! Overwrite libmysql: Yes, does not help. It seems to me that there is some general problem with MySql, but the DB server seems to be running fine. I'm really out of ideas of things I could try, so I'm desperate for any hints or tricks.

  • Change find() type of contained model or array transformation

    - by Ramon Marco Navarro
    I have the following model associations: Response->Survey Response->Question Response->Choice Survey->Question Question->Choice I want to create a form where I could answer all the questions for one survey. So I used the following to return the needed data: $questions = $this->Response->Question->find('all', array( 'conditions' => array('survey_id' => $id), 'contain' => array('Choice') ) ); Sample output for debug($questions). Questions Is there a contain() option so that an associated model returns in the find('list') format so that I could use: foreach($question as $questions) { $this-Form-select('field_name', $question['Choice']); } If no option is available, how could I do this using PHP's builting array methods? PS: The foreach block won't turn into a code block. If someone could edit and fix it, please do so and delete this line. Thank you.

  • Book Review: Expert Cube Development with Microsoft SQL Server 2008 Analysis Services

    - by Greg Low
    I spent last week on campus in Redmond with the SQL Server Analysis Services Maestro program. It was great to have a chance to focus on SSAS for a week. As part of that, I did quite a bit of reading as I had quite a bit of travelling time. Ironically, I re-read a few books. The first was Marco Russo, Alberto Ferrari and Chris Webb's book Expert Cube Development with Microsoft SQL Server 2008 Analysis Services . I've often told BI classes that I've been teaching that this is a really good book and...(read more)

El Dialogo CxO , organizado por Econique, y en el que participó Oracle, tuvo lugar en Madrid en el Hotel Puerta de Ámerica. Este encuentro tenía como objetivo intercambiar opiniones sobre todos los aspectos relacionados con la gestión estratégica de clientes y el Contact Centre. En este marco, los asistentes tuvieron la oportunidad de realizar reuniones “one to one” con nuestros mejores expertos. Además Oracle presentó dos coloquios relacionados con la visión de las "Nuevas necesidades, estrategias y tendencias en la gestión del Marketing", de la mano de Gema Sebastian, Principal Sales Consultant de Oracle. En dichos coloquios los participantes de empresas, como Caprabo, Carrefour, Endesa, Jaguar Land Rover y Repsol (entre otros) trataron temas de máxima actualidad para los directivos de Marketing. Esta mesa redonda se centró sobre todo en el Marketing en redes sociales, compartiendo entre todos nuestra percepción de que es algo necesario pero que todavía el mercado no sabe muy bien cómo tratar. La escucha activa dentro de las redes y la posibilidad de reaccionar ante determinados factores se veía como un claro punto donde comenzar a trabajar de manera activa y donde Oracle puede ayudar. La experiencia de cliente fue otro de los puntos tratados en esta mesa, donde se dejó claro que ahora es el consumidor el que manda, el que quiere ver las cosas donde quiere y como quiere y que un mensaje de marketing ha de darse en el momento adecuado y aportando un valor real para que el consumidor lo acepte como algo interesante. Igualmente Oracle dispone de herramientas para hacer que esto sea posible. Por otro lado, en Lisboa, tenía lugar el Total Training 2012, una conferencia organizada por el Grupo IFE. En ella participaron más de 100 profesionales de los recursos humanos de las empresas más importantes de Portugal y tuvo como base de partida los conocimientos y experiencias, el intercambio de ideas y la discusión de oportunidades a las que actualmente se enfrentan los profesionales de este área. En este marco Oracle realizó una ponencia sobre “Los nuevos conceptos en RRHH”, de la mano de Julio Rodriguez, Principal Sales Consultant de Oracle, y que puso de manifiesto algunos conceptos tecnológicos relevantes para la gestión del talento que por su novedad, no eran muy conocidos por los profesionales de los RRHH cómo: · Saas (Software as a service) · BI (Business Intelligence) para RRHH · Social Networking y cómo integrarla dentro de la empresa · El mapa del talento, por fin fuera del Excel y en una aplicación · La movilidad en las aplicaciones de RRHH. Sin duda, esta fue una jornada cargada de intercambio de experiencias y de conocimientos para dos grandes áreas: los Recursos Humanos y la Gestión Estratégica del cliente.

  • Anyone else experiencing high rates of Linux server crashes during a leap second day?

    - by Bron Gondwana
    POSTMORTEM Anticlimax: only thing that died was my VPN (openvpn) link to the cluster, so there was an exciting few seconds while it re-established. Everything else was fine. Starting back ntp everywhere. If you look at Marco's blog at http://my.opera.com/marcomarongiu/blog/2012/06/01/an-humble-attempt-to-work-around-the-leap-second - he has a solution for phasing the time change over 24 hours using ntpd -x to avoid the 1 second skip. Give that a go if it matters to you. For the systems I run, the jump isn't a problem. Just today, Sat June 30th - starting soon after the start of the day GMT. We've had a handful of blades in different datacentres as managed by different teams all go dark - not responding to pings, screen blank. They're all running Debian Squeeze - with everything from stock kernel to custom 3.2.21 builds. Most are Dell M610 blades, but I've also just lost a Dell R510 and other departments have lost machines from other vendors too. There was also an older IBM x3550 which crashed and which I thought might be unrelated, but now I'm wondering. The one crash which I did get a screen dump from said: [3161000.864001] BUG: spinlock lockup on CPU#1, ntpd/3358 [3161000.864001] lock: ffff88083fc0d740, .magic: dead4ead, .owner: imapd/24737, .owner_cpu: 0 Unfortunately the blades all supposedly had kdump configured, but they died so hard that kdump didn't trigger - and they had console blanking turned on. I've disabled console blanking now, so fingers crossed I'll have more information after the next crash. Just want to know if it's a common thread or "just us". It's really odd that they're different units in different datacentres bought at different times and run by different admins (I run the FastMail.FM ones)... and now even different vendor hardware. Most of the machines which crashed had been up for weeks/months and were running 3.1 or 3.2 series kernels. The most recent crash was a machine which had only been up about 6 hours running 3.2.21. THE WORKAROUND Ok people, here's how I worked around it. disabled ntp: /etc/init.d/ntp stop created http://linux.brong.fastmail.fm/2012-06-30/fixtime.pl (code stolen from Marco, see blog posts in comments) ran fixtime.pl without an argument to see that there was a leap second set ran fixtime.pl with an argument to remove the leap second NOTE: depends on adjtimex. I've put a copy of the squeeze adjtimex binary at http://linux.brong.fastmail.fm/2012-06-30/adjtimex - it will run without dependencies on a squeeze 64 bit system. If you put it in the same directory as fixtime.pl, it will be used if the system one isn't present. Obviously if you don't have squeeze 64 bit... find your own. I'm going to start ntp again tomorrow. As an anonymous user suggested - an alternative to running adjtimex is to just set the time yourself, which will presumably also clear the leapsecond counter.

  • SQLRally Nordic gets underway

    - by Rob Farley
    PASS is becoming more international, which is great. The SQL Community has always been international – it’s not as if data is only generated in North America. And while it’s easy for organisations to have a North American focus, PASS is taking steps to become international. Regular readers will be aware that I’m one of three advisors to the PASS Board of Directors, with a focus on developing PASS as a more global organisation. With this in mind, it’s great that today is Day 1 of SQLRally Nordic, being hosted in in Sweden – not only a non-American country, but one that doesn’t have English as its major language. The event has been hosted by the amazing Johan Åhlén and Raoul Illyés, two guys who I met earlier this year, but the thing that amazes me is the incredible support that this event has from the SQL Community. It’s been sold out for a long time, and when you see the list of speakers, it’s not surprising. Some of the industry’s biggest names from Microsoft have turned up, including Mark Souza (who is also a PASS Director), Thomas Kejser and Tobias Thernström. Business Intelligence experts such as Jen Stirrup, Chris Webb, Peter Myers, Marco Russo and Alberto Ferrari are there, as are some of the most awarded SQL MVPs such as Itzik Ben-Gan, Aaron Bertrand and Kevin Kline. The sponsor list is also brilliant, with names such as HP, FusionIO, SQL Sentry, Quest and SolidQ complimented by Swedish companies like Cornerstone, Informator, B3IT and Addskills. As someone who is interested in PASS becoming global, I’m really excited to see this event happening, and I hope it’s a launch-pad into many other international events hosted by the SQL community. If you have the opportunity, thank Johan and Raoul for putting this event on, and the speakers and sponsors for helping support it. The noise from Twitter is that everything is going fantastically well, and everyone involved should be thoroughly congratulated! @rob_farley

  • Session Mania: Content Catalog & Suggest-a-Session

    - by Justin Kestelyn
    As ably reported in the Oracle Technology Network blog, the Oracle Develop Conference's content catalog is now public (as are the catalogs for JavaOne and Oracle OpenWorld), meaning you can now explore technical sessions scheduled for the conf to your heart's content."But something's missing", you may tell yourself. "Where is my favorite subject, the one I happen to also be an expert on?" Well, there's good news for you, too: The Suggest-A-Session project has returned. It works thus: Submit a session idea via Oracle Mix and ask your colleagues, Oracle Mix community, friends and anyone else you know to vote for your session. (You must be an Oracle Mix member to vote.) Voting is open through June 20. For the most part, the top voted sessions will be selected for the Oracle Develop Conf (or Oracle OpenWorld) official agenda. See the FAQ for fine print.Apparently some people have already jumped into this loophole, including Oracle ACE Director Marco Gralike, who has "gone video" on us: Why wait? Suggest-a-session!
