How do I make it so the subclasses can add members to the Parameters class?

  • Rails Nested Attributes, Relationship for Shared or Common Object

    - by SooDesuNe
    This has to be a common problem, so I'm surprised that Google didn't turn up more answers. I'm working on a rails app that has several different kinds of entities, those entities by need a relation to a different entity. For example: Address: a Model that stores the details of a street address (this is my shared entity) PersonContact: a Model that includes things like home phone, cell phone and email address. This model needs to have an address associated with it DogContact: Obviously, if you want to contact a dog, you have to go to where it lives. So, PersonContact and DogContact should have foreign keys to Address. Even, though they are really the "owning" object of Address. This would be fine, except that accepts_nested_attributes_for is counting on the foreign key being in Address to work correctly. What's the correct strategy to keep the foreign key in Address, but have PersonContact and DogContact be the owning objects?

  • running requestAnimationFrame from within a new object

    - by JVE999
    I'm having trouble running an animation. This is inside var ob1 = function() {};. When called, it runs for a while and then I get the error Uncaught RangeError: Maximum call stack size exceeded. However, this same structure has no problems running outside of the object. /////////////// Render the scene /////////////// this.render = function (){ renderer.render(scene,camera); if(isControls == true) controls.update(clock.getDelta()); this.animate(); //console.log(true); requestAnimationFrame(this.render()); } /////////////// Update objects /////////////// this.animate = function (){ console.log("!"); }

  • jQuery object are immutable?

    - by Daniel
    Hello a new noob on jQuery here and I was wondering if jQuery objects are immutable. For example: var obj1 = $("<tag></tag>"); var obj2 = obj1.append("something"); Will obj1 and obj2 be the same meaning obj2 will reference obj1? UPDATE: The above example kind of scratches the surface of what i want to know, a more accurate question is : If i chain function from the jQuery api will they return the same object or a new one (as the case with strings in Java)?

  • VNC Server not responsive after a few days

    - by assylias
    I am new to Ubuntu (11.10) - I installed Ubuntu on a box which has no screen and no keyboard. I connect to that box via tightvncserver. The box is mostly used as a file and media server (i.e. samba + XBMC). So far so good. I can connect via VNC to the box and take control of it. But after a few days, when trying to connect via VNC, I don't get a response. The media server is still on, ping is fine, but VNC is down. The only solution I have found is to plug a screen and keyboard and reboot. I am not sure how to diagnose the problem (maybe some log files?) or if this is just a configuration issue. Any help appreciated.

  • Alt/Shift key not released after switching keyboard layout

    - by szx
    Sometimes when I switch layout using either Alt+Shift or Ctrl+Shift the Alt key is not recognized as being released thus if I press e.g. F a File menu opens up. Last time that happend I lost all data I filled into a text form on a webpage because I pressed the Home key while typing and Firefox suddenly went to my home page! Moreoever, it still remains unreleased after hundreds of keypresses like if I'm holding it! Same goes for the Shift key. I would rather file a bug at Launchpad if I could but I have no clue what fucking package name should I type in the ubuntu-bug command! Have anyone else had this issue? Can you suggest a solution or maybe another place to report this bug?

    I saved a PublicKey instance in a file using ObjectOutputStream. This file is then stored inside a jar file which is then loaded by JBoss.

  • Google Analytics goal funnel does not recognize virtual page views

    - by Webber Smith
    I have a setup wizard with 3 steps. Since I'm using AJAX each step uses a virtual pageview with an appropriate URL for each step (see below). The pageviews are being recorded in the Content section of Google Analytics but the Goal Funnel still shows zero for each step. I've tried advise on other forums such as... Make sure Goal URL is set to Exact match Make sure no steps or the Goal URL are a parent directory of any other steps. For example, don't track /wizard/ as a Goal/step and track /wizard/step2/. Not sure why this would be a problem since it is an exact match, but it shouldn't hurt so I tried it... Require (or don't require - tried both) the first step in the funnel ...but none of these seem to work. Thoughts? Goal Settings Exact match : "/wizard/setup-complete/" Funnel Step 1 : "/wizard/step1/" Step 2 : "/wizard/step2/" Step 3 : "/wizard/step3/"

  • Closing lid does not suspend laptop

    - by fgysin
    I'm on a Lenovo T400 laptop. In the past I had suspend problems on every second version of Ubuntu (at least it feels like it), but in 11.04 it was working perfectly. Now, after the upgrade to 11.10 closing the laptop lid does no longer initialize suspension. When I choose 'Suspend' from the shutdown menu it works perfectly, so this does not seem to be an issue with suspend itself. The options in System Settings>Power are of course set to suspend in case of closing the lid (both for battery and AC poer). Note: I have no idea if this is of any importance, but I'm running the gnome-session-fallback stuff, as I just hate the Unity desgin.

  • 301 redirects - can we not delete old pages?

    - by KBS
    First time here :) We have a page on the site which ranks well for an SEO term (top 5) but contains old information. We have added a new page but Google doesn't rank it that well. Information on these pages is time sensitive. Old: example.com/2013-related-information.html New: example.com/2014-related-information.html Obvious solution is to delete old page and do a 301 redirect to the new page. Now, can we still keep the old page by giving it a new URL. Step1: example.com/2013-related-information.html is redirect to example.com/2014-related-information.html Step2: example.com/2014-related-information.html is recreated with a new address such as example.com/new-2013-related-information.html What we are trying to do is to send the user to the fresh page but still not wasting the record copy if someone wants to go and dig up old page. Would appreciate help!! Cheers

  • T9 patented while QWERTY is not?

    - by Marco W.
    I've seen that there are lots of custom keyboards for Android, but all are QWERTY keyboards. I couldn't find any keyboard with T9 layout. Is this because T9 is patented and the QWERTY layout is not? So if I made a T9 keyboard, I would have to pay patent fees? So what does the patent protect when you look at T9? Only the layout? Or the prediction engine? The problem is, this way of predicting words is the only one that makes sense for this layout ...

  • command-line zip not working

    - by ptriek
    I have a Wordpress site on a Debian/Linux dedicated server, with a Backupbuddy plugin for making automatic backups. The plugin, however, gives an error 'Your server does not support command line ZIP'. My knowledge of Linux commands is very limited, but I managed installing zip with the command sudo apt-get install zip However, I still get the same error message. Plugin documentation mentions the problem could also be caused by disabled exec() or safe_mode - but exec isn't disabled, and safe_mode is off. Any ideas what might be causing this, or how to fix it? The only thing I could think of, is it might be caused by wrong permissions?

  • Proxy object references in MVC code

    - by krystan honour
    Hi there, I am just figuring out best practice with MVC now I have a project where we have chosen to use it in anger. My question is. If creating a list view which is bound to an IEnumerable is this bad practise? Would it be better to seperate the code generated by the WCF Service reference into a datastructure which essentially holds the same data but abstracts further from the service, meaning that the UI is totally unaware of the service implementation beneath. or do people just bind to the proxy object types and have done with it ? My personal feeling is to create an abstraction but this seems to violate the DRY principle.

  • Question of using static_cast on "this" pointer in a derived object to base class

    - by Johnyy
    Hi, this is an example taken from Effective C++ 3ed, it says that if the static_cast is used this way, the base part of the object is copied, and the call is invoked from that part. I wanted to understand what is happening under the hood, will anyone help? class Window { // base class public: virtual void onResize() { } // base onResize impl }; class SpecialWindow: public Window { // derived class public: virtual void onResize() { // derived onResize impl; static_cast<Window>(*this).onResize(); // cast *this to Window, // then call its onResize; // this doesn't work! // do SpecialWindow- } // specific stuff };

  • Choosing a design pattern for a class that might change it's internal attributes

    - by the_drow
    I have a class that holds arbitrary state and it's defined like this: class AbstractFoo { }; template <class StatePolicy> class Foo : public StatePolicy, public AbstractFoo { }; The state policy contains only protected attributes that represent the state. The state might be the same for multiple behaviors and they can be replaced at runtime. All Foo objects have the same interface to abstract the state itself and to enable storing Foo objects in containers. I would like to find the least verbose and the most maintainable way to express this.

    I am using Ubuntu 12.04 as my OS. Till yesterday, my LAN was working fine , but after that my LAN is not working properly. What I mean is that it shows that the LAN wire is connected properly, but when I try to open a website it gets stuck on resolving host. I am using the web browser as Google-chrome.

Can anybody, help me with a solution to this problem.

  • Objective C Object Functioning & Passing Arrays

    - by Patrick
    I apologise if this has been asked before but I can't find the info I need. Basically I want a UITableView to be populated using info from a server, similar to the SeismicXML example. I have the parser as a separate object, is it correct to alloc, init an instance of that parser & then tell RootViewController to make it's table data source a copy of the parser's array. I can't include code because I haven't written anything yet, I'm just trying to get the design right before I start. Perhaps something like: xmlParser = [[XMLParser alloc] init]; [xmlParser getXMLData]; // Assuming xmlParser stores results in an array called returnedArray self.tableDataSource = xmlParser.returnedArray Is this the best way of doing it?

  • C# - Rollback SqlTransaction in catch block - Problem with object accessability

    - by Marks
    Hi there. I've got a problem, and all articles or examples i found seem to not care about it. I want to do some database actions in a transaction. What i want to do is very similar to most examples: using (SqlConnection Conn = new SqlConnection(_ConnectionString)) { try { Conn.Open(); SqlTransaction Trans = Conn.BeginTransaction(); using (SqlCommand Com = new SqlCommand(ComText, Conn)) { /* DB work */ } } catch (Exception Ex) { Trans.Rollback(); return -1; } } But the problem is, that the SqlTransaction Trans is declared inside the try block. So it is not accessable in the catch() block. Most examples just do Conn.Open() and Conn.BeginTransaction() before the try block. But i think thats a bit risky, since both can throw multiple exceptions. Am I wrong, or do most people just ignore this risk? Whats the best solution to be able to rollback, if an exception happens. Thanks in advance, Marks
