  • How to change scope data in controller?

    - by Derooie
    I am a real newbie at angular. I created something now which will let me retrieve and add items via angular and get/put them in mongodb. I use express and mongoose in the app The question is, how can i modify the data before it reaches the DOM in the controller. In this example i have created a way to retrieve data, and i get it exactly as it is stored in mongodb. What i would like is that the field where i store 1 or 0 in the database, to be shown as text. So if mongo has a value 1 i get "the value in mongo is 1" and when the field has a value of 0 get "the value is zero". (just as an example, i like other texts, but it illustrate what i want) I post my controller, html and current output. Any help would be appreciated. Controller function getGuests($scope, $http) { $scope.formData = {}; $http.get('/api/guests') .success(function(data) { $scope.x = data; }) .error(function(data) { console.log('Error: ' + data); }); } HTML <div ng-controller="getGuests"> <div ng-repeat="guest in x"> {{ guest.voornaam }} {{ guest.aanwezig }} </div> </div> The current scope output, what i see in HTML. I like to change only the value of "aanwezig" in case the value of aanwezig is 0 or 1. firstname1 1 firstname2 0 Something else, but would be great to learn, is how i can do a specific mongodb query by the push of a button and get that result.

  • Apache: scope for environmental variables

    - by Anonymous
    While there's documentation available on Apache environmental variables, I can not find answer to one important question. Imagine I use rewrite rules to set environmental variable RewriteRule ... ... [E=something:1] What is the scope of "something" - global Apache server (this means "something" will be available for other request transactions), this request (means that "something" is only valid for THIS http request (and its related processing - but what's about internal redirects and other internal stuff - are they considered as THIS request, or another one?), and may be set differently within another (concurrent) request?

  • iPhone development: Best method to allow user to chose search scope

    - by Mark Pemburn
    Hi, I'm developing my first iPhone app and want to allow the user to select the scope of their search in a more complex way than the 'scope buttons' permit. The app is related to wines and I want to the user to be able to select the 'color' (Red, White, Blush, etc.) first, and then select the type/varietal within that category. Right now, I'm using the UISearchBar's scope buttons for the colors and tapping the button opens a view with the selection of colors. This is okay except that once the 'Red' button has been selected, I can't select it a second time to change my choice of type (e.g., change from 'Merlot' to 'Syrrah', etc.) If there's a better way to do this, I'm willing to scrap my method and start from scratch. Thanks!

  • How to call angular javascript directive methods from the global scope

    - by user1659278
    I have a directive like the one of the examples from AngularJS, shown below. How can I call the toggle method from the global scope? I want to be able to toggle the zippy from some legacy code. myApp.directive('zippy', function(){ return { restrict: 'E', replace: true, transclude: true, scope: { title:'bind' }, template: '<div class="zippy">' + '<div class="title">{{title}}</div>' + '<div class="body" ng-transclude></div>' + '</div>', link: function(scope, element, attrs) { var title = angular.element(element.children()[0]), opened = true; title.bind('click', toggle); function toggle() { opened = !opened; element.removeClass(opened ? 'closed' : 'opened'); element.addClass(opened ? 'opened' : 'closed'); } toggle(); } } });

  • When to use @Singleton in a Jersey resource

    - by dexter
    I have a Jersey resource that access the database. Basically it opens a database connection in the initialization of the resource. Performs queries on the resource's methods. I have observed that when I do not use @Singleton, the database is being open at each request. And we know opening a connection is really expensive right? So my question is, should I specify that the resource be singleton or is it really better to keep it at per request especially when the resource is connecting to the database? My resource code looks like this: //Use @Singleton here or not? @Path(/myservice/) public class MyResource { private ResponseGenerator responser; private Log logger = LogFactory.getLog(MyResource.class); public MyResource() { responser = new ResponseGenerator(); } @GET @Path("/clients") public String getClients() { logger.info("GETTING LIST OF CLIENTS"); return responser.returnClients(); } ... // some more methods ... } And I connect to the database using a code similar to this: public class ResponseGenerator { private Connection conn; private PreparedStatement prepStmt; private ResultSet rs; public ResponseGenerator(){ Class.forName("org.h2.Driver"); conn = DriverManager.getConnection("jdbc:h2:testdb"); } public String returnClients(){ String result; try{ prepStmt = conn.prepareStatement("SELECT * FROM hosts"); rs = prepStmt.executeQuery(); ... //do some processing here ... } catch (SQLException se){ logger.warn("Some message"); } finally { rs.close(); prepStmt.close(); // should I also close the connection here (in every method) if I stick to per request // and add getting of connection at the start of every method // conn.close(); } return result } ... // some more methods ... } Some comments on best practices for the code will also be helpful.

  • Using scope, defined in parent model, inside it's child (STI pattern)

    - by Anton
    I implement a class hierarchy using STI pattern class A scope :aaa, where([someField]:[someValue]) end class B < A end The problem is that when I try to call something like: B.limit(5).aaa => SELECT "[table]".* FROM "[table]" WHERE "[table]"."type" IN ('A') AND ([someField] = [someValue]) LIMIT 5 So I am getting 5 objects of type A, which satisfies scope :aaa But I need to do the same with rows where type = "B" Is there any way to use scopes from parent, without redifinning it in childs in STI pattern? Thanks in advance EDITED I just discussed it with my frind and he showed me one important thing. A in not the root class of STI. IN fact whole hierarchy looks like class O < ActiveRecord::Base end class A < O scope ..... ..... end class B < A end maybe the reason is in hierarchy itself?...

  • Rails Scope for association of 0 size.

    - by MissingHandle
    I'm having trouble figuring out the scope method for all the Foos that have no Bars. That is: class Foo < ActiveRecord::Base has_may :bars end class Bar < ActiveRecord::Base belongs_to :foo end I'd like to write a scope method that returns me all the foos that have no bars. Something like: class Foo < ActiveRecord::Base has_may :bars scope :has_no_bars, includes(:bars).where("COUNT(foo.bars) = 0") end But I don't understand the appropriate syntax. Any help? Happy to use a MetaWhere solution if easier.

  • Why ADF Developers Should Attend ODTUG This Year

    - by shay.shmeltzer
    If you are using Oracle ADF or planning to pick it up in the next year, I would encourage you to try and attend this year's ODTUG K-Scope conference. If you are not familiar with it, ODTUG - the Oracle Development Tools User Groups - holds a yearly conference that is very technical in nature. It is not a huge conference in terms of the number of attendees, but this just means that you have more opportunities to interact with Oracle ACEs, Oracle Product Managers, and other developers. The conference is known to be a no-fluff, no-marketing, technical conference. This year however there is one key new thing that should be of interest to readers of this blog. A new track called the "Fusion Middleware" track has been formed and it has lots of sessions for any level of ADF developer. The track is run by several Oracle ACEs who are also involved in the ADF Enterprise Methodology Group. They have sessions for every level of ADF awareness - from the beginner to the expert, and you can also learn about related technologies such as WebCenter and SOA Suite. Most of the sessions are run by users who share their real world experience with the technology. And me and other PMs will also be running a few sessions and hands-on labs there. Check out the list of sessions in the Fusion Middleware track. And don't miss the Sunday symposium too.

  • Is my JS/Jquery methodology good?

    - by absentx
    I always struggle with which of the stack sites is best to post "questions of theory" like this, but I think programmers is the best, if not, as usual a mod will move it etc... I am seeking critique on what has become my normal methodology of writing javascript. I have become heavily reliant on the Jquery library, but I think this has helped me learn the native language better also. Anyways, please critique the following style of JS coding...buried are a lot of questions of scope, if you could point out the strengths and weaknesses of this style I would appreciate it. var critique ={ start: function(){ globalness = 'GLOBAL-GLOBAL'; //available to all critique's methods var notglobalness = 'LOCAL-LOCAL';// only available to critiques start method //am I using the "method" teminology properly here?? $('#stuff').on('click','a.closer-target',function(){ $target = $(this); if($target.hasClass('active')){ $target.removeClass('active'); } else{ $target.addClass('active'); critique.madness($target); } }) console.log(notglobalness+': at least I am useful at home'); console.log('note here that: '+notglobalness+' is no longer available after this point, lets continue on:'); critique.madness(notglobalness); }, madness: function($e){ // do a bunch of awesomeness with $e //but continue to keep it seperate because you think its best to keep things isolated. //send to the next function when complete here console.log('here is globalness, which is still available from the start method of critique!! ' + globalness); console.log('lets see if the globalness carries on to a new var object!!'); console.log('the locally isolated variable of NOTGLOBALNESS is available here because it was passed to this method, lets show it:'+$e); carryOn.start(); } } //end critique var carryOn={ start: function(){ console.log('any chance critique.globalness will work here??? lets see: ' +globalness); console.log('it absolutely does'); } } $(document).ready(critique.start);

  • WebLogic Server Weekly for March 26th, 2012: WLS 1211 Update, Java 7 Certification, Galleria, WebLogic for DBAs, REST and Enterprise Architecture, Singleton Services

    - by Steve Button
    WebLogic Server 12c Certified with Java 7 for Production Use WebLogic Server 12c (12.1.1) has been certified with JDK 7 for development usage since December and we have now completed JDK 7 certification for use with production systems. In doing so, we have updated the WebLogic Server 12c (12.1.1) distributions incorporating fixes associated with JDK 7 support as well as some bundled patches that address several issues that have been discovered since the initial release. These updated distributions are available for download from OTN and will be beneficial for all WebLogic Server 12c (12.1.1) users in general. What's New Release Notes Download Here! Updated Oracle WebLogic Server 12.1.1.0 distribution Never one to miss a trick, Markus Eisele was one of the first to notice the WebLogic Server 12c update and post a blog about it. Sources told me that as of Friday last week you have an updated version of WebLogic Server 12c on OTN. http://blog.eisele.net/2012/03/updated-oracle-weblogic-server-12110.html Using WebLogic Server 12c with Java 7 - Video To illustrate the use of Java 7 with WebLogic Server 12c, I put together a screen cam showing the creation of a domain using Java 7 and then build and deploy a simple web application that uses Java 7 syntax to show it working. Ireland OUG Presentation: WebLogic for DBAs Simon Haslam posted his slides from a presentation he gave Dublin on 21/3/12 at the OUG Ireland conference. In this presentation, he explains the core concepts and ideas behind WebLogic Server, walks through an installation and offers some tips and common gotcha's to avoid. Simon also covers some aspects of installing and use Enterprise Manager 12c. Note: I usually install the JVM and use the generic .jar installer rather than using an installer bundled with a JVM. http://www.slideshare.net/Veriton/weblogic-for-dbas-10h Slightly Retro: Jeff West on Enterprise Architecure and REST In this weeks flashback, we look at Jeff West's blog from early 2011 where he provides some thoughtful opinions on enterprise architecture and innovation, then jumps into his views on REST. After I progressed in my career and did more team-leading and architecture type roles I was ‘educated’ on what it meant to have Asynchronous and Long-Running processes as part of your Enterprise Application architecture. If I had a synchronous process then I needed a thread available to service the request and then provide the response. https://blogs.oracle.com/jeffwest/entry/weblogic_integration_wli_web_services_and_soap_and_rest_part_1 Starting Managed Servers without an Administration Server using Node Manager and WLST Blogger weblogic-tips shows how to start a managed server without going through the Administration Server, using the Node Manager and WLST. Connect WLST to a Node Manager by entering the nmConnect command. http://www.weblogic-tips.com/2012/02/18/starting-managed-servers-without-an-administration-server-using-node-manager-and-wlst/ Using WebLogic Server Singleton Services WebLogic Server has supported the notion of a Singleton Service for a number of releases, in which WebLogic Server will maintain a single instance of a configured singleton service on one managed server within a cluster. This blog demonstrates how the singleton service can be accessed and used from applications deployed on the cluster. http://buttso.blogspot.com.au/2012/03/weblogic-server-singleton-services.html

  • Creating an app pool a month to limit the scope of issues

    - by user39550
    I have about 360 sites running on a single app pool. Now I know we have a coding issue with one of those sites, were we have accidentally coded a memory leak. So what happens is the site runs, the memory leak starts and soon the app pool runs out of memory. Then slowly but surely, the rest of the 360 sites start going down like a domino affect. I understand that the root of the problem is some bad coding, which we'll fix, but instead of bringing down said 360 sites, I was thinking, we could create a new app-pool monthly that every site we create would go into that months app pool. First, that limit the scope of the issues to 5 - 20 sites and second if one site started having issues we wouldn't be bringing down all 360 sites. Is there any issues to this thinking, possible ramifications? Thanks in Advance! Jeremiah

  • How to reach a Global Scope IPv6 host?

    - by Vaibhav Bajpai
    I have setup DNS64+NAT64 on a machine with 2 interfaces: eth0: public IPv4 address (connected to outside world) eth1: global scope IPv6 address: 2001::/64 I can successfully use ping6 google.com on this machine. Now I want to connect my MacBook to this machine by making it an IPv6-only client and perform some tests, but I do not have an IPv6 address assigned on this MacBook. I'm wondering, how should I manually assign one so as to route all my IPv6 traffic (I will disable IPv4 on my MacBook) to this machine, which will be picked up by DNS64+NAT64 to be converted to IPv4 requests and sent to the outside world?

  • Question regarding IPv6 - Solicited-Node Address with a Link local scope

    - by Pulse
    Situation: A small LAN comprising a Windows 7 Ultimate x54 PC, 2 XP Pro x86 PCs and an Asus router.The Win 7 box has IPv6 enabled. There are no other IPv6 enabled devices on the LAN. In my firewall I see numerous requests originating from the Win 7 PC, which are for the Multicast address ff02::1:ff.... which is a Solicited-Node address query and has a scope of 2 which equates to the local link. As far as I knew local link addresses are filtered by routers, hence local link. Given that situation I'm wondering why I'm seeing these queries being generated to various addresses? Any ideas? Thanks.

  • Managing software projects - advice needed

    - by Callum
    I work for a large government department as part of an IT team that manages and develops websites as well as stand alone web applications. We’re running in to problems somewhere in the SDLC that don’t rear their ugly head until time and budget are starting to run out. We try to be “Agile” (software specifications are not as thorough as possible, clients have direct access to the developers any time they want) and we are also in a reasonably peculiar position in that we are not allowed to make profit from the services we provide. We only service the divisions within our government department, and can only charge for the time and effort we actually put in to a project. So if we deliver a project that we have over-quoted on, we will only invoice for the actual time spent. Our software specifications are not as thorough as they could be, but they always include at a minimum: Wireframe mockups for every form view A data dictionary of all field inputs Descriptions of any business rules that affect the system Descriptions of the outputs I’m new to software management, but I’ve overseen enough software projects now to know that as soon as users start observing demos of the system, they start making a huge amount of requests like “Can we add a few more fields to this report.. can we redesign the look of this interface.. can we send an email at this part of the workflow.. can we take this button off this view.. can we make this function redirect to a different screen.. can we change some text on this screen… can we create a special account where someone can log in and get access to X… this report takes too long to run can it be optimised.. can we remove this step in the workflow… there’s got to be a better image we can put here…” etc etc etc. Some changes are tiny and can be implemented reasonably quickly.. but there could be up to 50-100 or so of such requests during the course of the SDLC. Other change requests are what clients claim they “just assumed would be part of the system” even if not explicitly spelled out in the spec. We are having a lot of difficulty managing this process. With no experienced software project managers in our team, we need to come up with a better way to both internally identify whether work being requested is “out of spec”, and be able to communicate this to a client in such a manner that they can understand why what they are asking for is “extra” work. We need a way to track this work and be transparent with it. In the spirit of Agile development where we are not spec'ing software systems in to the ground and back again before development begins, and bearing in mind that clients have access to any developer any time they want it, I am looking for some tips and pointers from experienced software project managers on how to handle this sort of "scope creep" problem, in tracking it, being transparent with it, and communicating it to clients such that they understand it. Happy to clarify anything as needed. I really appreciate anyone who takes the time to offer some advice. Thanks.

However, I bump into problem when, in my app, I want to display search result with empty search string but selected scope button. It seems like it's a must to enter some search string in order to get the search result table being initialized and displayed. Is there any ways to display search result immediately after user has picked a scope but not entered search word yet? Thanks Bill

  • How to use Multiple Variables for a lock Scope in C#

    - by Gunner
    I have a situation where a block of code should be executed only if two locker objects are free. I was hoping there would be something like: lock(a,b) { // this scope is in critical region } However, there seems to be nothing like that. So does it mean the only way for doing this is: lock(a) { lock(b) { // this scope is in critical region } } Will this even work as expected? Although the code compiles, but I am not sure whether it would achieve what I am expecting it to.
