  • How to get a nicely formatted PHP Web Service response?

    - by Bruno
    I called an API like this: $service = new Class_Service(); $parameters = new GetClasses(); $parameters->Request = new GetClassesRequest(); $parameters->Request->SourceCredentials = new SourceCredentials(); $parameters->Request->SourceCredentials->SourceName = "Name"; $parameters->Request->SourceCredentials->Password = "Pass"; $parameters->Request->SourceCredentials->SiteIDs = array( 12 ); $classes = $service->GetClasses($parameters); var_dump($classes); And received a response like this: object(GetClassesResponse)#7 (1) { ["GetClassesResult"]=> object(GetClassesResult)#8 (6 { ["Classes"]=> object(stdClass)#9 (1) { ["Class"]=> array(25) { [0]=> object(Mi_Class)#10 (21) { ["ClassScheduleID"]=> int(15) ["Visits"]=> NULL ["Clients"]=> NULL ["Location"]=> object(Location)#11 (30) { ["BusinessID"]=> NULL ["SiteID"]=> int(12) ["BusinessDescription"]=> NULL ["AdditionalImageURLs"]=> object(stdClass)#12 (0) { } ["FacilitySquareFeet"]=> NULL Does a response normally look like this? How do I go about getting the data in a formatted manner?

  • Is it possible to cancel function override in parent class and use function from top level parent

    - by Anatoliy Gusarov
    class TopParent { protected function foo() { $this->bar(); } private function bar() { echo 'Bar'; } } class MidParent extends TopParent { protected function foo() { $this->midMethod(); parent::foo(); } public function midMethod() { echo 'Mid'; } public function generalMethod() { echo 'General'; } } Now the question is if I have a class, that extends MidParent because I need to call class Target extends MidParent { //How to override this method to return TopParent::foo(); ? protected function foo() { } } So I need to do this: $mid = new MidParent(); $mid->foo(); // MidBar $taget = new Target(); $target->generalMethod(); // General $target->foo(); // Bar UPDATE Top parent is ActiveRecord class, mid is my model object. I want to use model in yii ConsoleApplication. I use 'user' module in this model, and console app doesn't support this module. So I need to override method afterFind, where user module is called. So the Target class is the class that overrides some methods from model which uses some modules that console application doesn't support.

  • multiple models in Rails with a shared interface

    - by dfondente
    I'm not sure of the best structure for a particular situation in Rails. We have several types of workshops. The administration of the workshops is the same regardless of workshop type, so the data for the workshops is in a single model. We collect feedback from participants about the workshops, and the questionnaire is different for each type of workshop. I want to access the feedback about the workshop from the workshop model, but the class of the associated model will depend on the type of workshop. If I was doing this in something other than Rails, I would set up an abstract class for WorkshopFeedback, and then have subclasses for each type of workshop: WorkshopFeedbackOne, WorkshopFeedbackTwo, WorkshopFeedbackThree. I'm unsure how to best handle this with Rails. I currently have: class Workshop < ActiveRecord::Base has_many :workshop_feedbacks end class Feedback < ActiveRecord::Base belongs_to :workshop has_many :feedback_ones has_many :feedback_twos has_many :feedback_threes end class FeedbackOne < ActiveRecord::Base belongs_to :feedback end class FeedbackTwo < ActiveRecord::Base belongs_to :feedback end class FeedbackThree < ActiveRecord::Base belongs_to :feedback end This doesn't seem like to the cleanest way to access the feedback from the workshop model, as accessing the correct feedback will require logic investigating the Workshop type and then choosing, for instance, @workshop.feedback.feedback_one. Is there a better way to handle this situation? Would it be better to use a polymorphic association for feedback? Or maybe using a Module or Mixin for the shared Feedback interface? Note: I am avoiding using Single Table Inheritance here because the FeedbackOne, FeedbackTwo, FeedbackThree models do not share much common data, so I would end up with a large sparsely populated table with STI.

  • Hibernate HQL m:n join problem

    - by smallufo
    I am very unfamiliar with SQL/HQL , and am currently stuck with this 'maybe' simple problem : I have two many-to-many Entities , with a relation table : Car , CarProblem , and Problem . One Car may have many Problems , One Problem may appear in many Cars, CarProblem is the association table with other properties . Now , I want to find Car(s) with specified Problem , how do I write such HQL ? All ids are Long type . I've tried a lot of join / inner-join combinations , but all in vain.. -- updated : Sorry , forget to mention : Car has many CarProblem Problem has many CarProblem Car and Problem are not directly connected in Java Object. -- update , java code below -- @Entity public class Car extends Model{ @OneToMany(mappedBy="car" , cascade=CascadeType.ALL) public Set<CarProblem> carProblems; } @Entity public class CarProblem extends Model{ @ManyToOne public Car car; @ManyToOne public Problem problem; ... other properties } @Entity public class Problem extends Model { other properties ... // not link to CarProblem , It seems not related to this problem // **This is a very stupid query , I want to get rid of it ...** public List<Car> findCars() { List<CarProblem> list = CarProblem.find("from CarProblem as cp where cp.problem.id = ? ", id).fetch(); Set<Car> result = new HashSet<Car>(); for(CarProblem cp : list) result.add(cp.car); return new ArrayList<Car>(result); } } The Model is from Play! framework , so these properties are all public .

  • implementing the generic interface

  • Is Domain Anaemia appropriate in a Service Oriented Architecture?

    - by Stimul8d
    I want to be clear on this. When I say domain anaemia, I mean intentional domain anaemia, not accidental. In a world where most of our business logic is hidden away behind a bunch of services, is a full domain model really necessary? This is the question I've had to ask myself recently since working on a project where the "domain" model is in reality a persistence model; none of the domain objects contain any methods and this is a very intentional decision. Initially, I shuddered when I saw a library full of what are essentially type-safe data containers but after some thought it struck me that this particular system doesn't do much but basic CRUD operations, so maybe in this case this is a good choice. My problem I guess is that my experience so far has been very much focussed on a rich domain model so it threw me a little. The remainder of the domain logic is hidden away in a group of helpers, facades and factories which live in a separate assembly. I'm keen to hear what people's thoughts are on this. Obviously, the considerations for reuse of these classes are much simpler but is really that great a benefit?

  • Get parameter values from method at run time

    - by Landin Martens
    I have the current method example: public void MethodName(string param1,int param2) { object[] obj = new object[] { (object) param1, (object) param2 }; //Code to that uses this array to invoke dynamic methods } Is there a dynamic way (I am guessing using reflection) that will get the current executing method parameter values and place them in a object array? I have read that you can get parameter information using MethodBase and MethodInfo but those only have information about the parameter and not the value it self which is what I need. So for example if I pass "test" and 1 as method parameters without coding for the specific parameters can I get a object array with two indexes { "test", 1 }? I would really like to not have to use a third party API, but if it has source code for that API then I will accept that as an answer as long as its not a huge API and there is no simple way to do it without this API. I am sure there must be a way, maybe using the stack, who knows. You guys are the experts and that is why I come here. Thank you in advance, I can't wait to see how this is done. EDIT It may not be clear so here some extra information. This code example is just that, an example to show what I want. It would be to bloated and big to show the actual code where it is needed but the question is how to get the array without manually creating one. I need to some how get the values and place them in a array without coding the specific parameters.

  • Using map() on a _set in a template?

    - by Stuart Grimshaw
    I have two models like this: class KPI(models.Model): """KPI model to hold the basic info on a Key Performance Indicator""" title = models.CharField(blank=False, max_length=100) description = models.TextField(blank=True) target = models.FloatField(blank=False, null=False) group = models.ForeignKey(KpiGroup) subGroup = models.ForeignKey(KpiSubGroup, null=True) unit = models.TextField(blank=True) owner = models.ForeignKey(User) bt_measure = models.BooleanField(default=False) class KpiHistory(models.Model): """A historical log of previous KPI values.""" kpi = models.ForeignKey(KPI) measure = models.FloatField(blank=False, null=False) kpi_date = models.DateField() and I'm using RGraph to display the stats on internal wallboards, the handy thing is Python lists get output in a format that Javascript sees as an array, so by mapping all the values into a list like this: def f(x): return float(x.measure) stats = map(f, KpiHistory.objects.filter(kpi=1) then in the template I can simply use {{ stats }} and the RGraph code sees it as an array which is exactly what I want. [87.0, 87.5, 88.5, 90] So my question is this, is there any way I can achieve the same effect using Django's _set functionality to keep the amount of data I'm passing into the template, up until now I've been passing in a single KPI object to be graphed but now I want to pass in a whole bunch so is there anything I can do with _set {{ kpi.kpihistory_set }} dumps the whole model out, but I just want the measure field. I can't see any of the built in template methods that will let me pull out just the single field I want. How have other people handled this situation?

  • Objective C iPhone performance issue

    - by Asad Khan
    Ok guys I am developing an iPhone app I have a Model class which follows a Singleton design pattern. Now I have an NSArray in it which is initialized to around some 1000 NSStrings in the init method. Now I need to use this data in some view controller. so I import Model.h, I create an array of NSString objects in view controller & set the data to it. But now the problem is that now I have 2000 NSStrings currently allocated, which I believe is not a good thing on iPhone due to memory considerations. releasing model object wont help because I've overrided release method to release nothing according to the pattern & I cannot change the design now because now a lot of code works on the assumption of model being a singleton. & in future maybe the initial NSStrings may grow to 2000 or even more & then I'll have 4000 NSStrings allocated at one time .... I am a little confused on how to go about it any suggestions

  • .htaccess file on localhost throwing an error when using a Virtual Host config on my Localhost!!

  • Allowing Xform controls for optional XML elements

    - by Cam
    Hi, In designing an XForm interface to an XML database (using eXist and XSLTForms), I'd like to include an input control for an optional element. The XML data records already exist and while some contain the optional element, others don't. To update a record, I'm using the existing XML record as the model instance. The problem is that the form control is not displayed when the optional element is not present, which is logical, but presents a problem when a user wants to add data to the optional element. To be more explicit, here's an example data record, data.xml: <a> <b>content</b> </a> with RNC schema: start = element a { element b { text }, element notes { text }? } XForms model: <xf:model> <xf:instance xmlns="" src="data.xml"/> <xf:submission id="save" method="post" action="update.xq" /> </xf:model> And control: <xf:input ref="/a/notes"> <xf:label>Notes (optional): </xf:label> </xf:input> The problem is that the 'Notes' input control is simply not displayed. An obvious solution is to add a trigger button to allow the user to insert the element if needed, but it is preferable to just have the input control appear, and be empty. My question is: is there some subtle combination of lesser-know attributes/binds/multiple instances/xpath expressions that will cause the control to always be displayed? Thanks

  • Does RazorEngine require MVC3 to be installed?

    - by tkha007
    I am working on a web project that uses MVC2. I decided to try out RazorEngine to do some e-mail templating. This appeared to work fine when I was protyping using an MVC2 project so I assumed that RazorEngine will work fine for my e-mail templating solution. What I had forgotten at the time was that I actually had MVC3 installed on my local development machine. After deploying the project on a pre-test server I get the following error in the logs when the application attempts to do anything with RazorEngine: Could not load file or assembly 'System.Web.Razor, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified. File name: 'System.Web.Razor, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' at RazorEngine.Compilation.DefaultCompilerServiceFactory.CreateCompilerService(Language language) at RazorEngine.Templating.TemplateService.CreateTemplateType(String razorTemplate, Type modelType) at RazorEngine.Templating.TemplateService.CreateTemplate[T](String razorTemplate, T model) at RazorEngine.Templating.TemplateService.Parse[T](String razorTemplate, T model) at RazorEngine.Razor.Parse[T](String razorTemplate, T model) at System.Dynamic.UpdateDelegates.UpdateAndExecute3[T0,T1,T2,TRet](CallSite site, T0 arg0, T1 arg1, T2 arg2) at Persistence.Utility.RazorEngineHelper.Parse(String templateName, Object model) in The fact that it can't find 'System.Web.Razor' means that this DLL does not exist on the deployed server. The only difference I can think of between the deployment server and my local dev machine is that the deployment server does not have MVC3 installed but I may be mistaken because the deployment server is not something I normally control and as such I don't have a lot of information about it. It is meant to host this particular application so there have been previous deployments of this application to this server. This is the first time I'm making a deployment with RazorEngine as a dependency.

  • What do I need to do if I want all typeof(MyEnum)'s to be handled with MyEnumModelBinder?

    - by Byron Sommardahl
    I have an Enum that appears in several of my models. For the most part, the DefaultModelBinder handles binding to my models beautifully. That it, until it gets to my Enum... it always returns the first member in the Enum no matter what is handed it by the POST. My googling leads me to believe I need to have a model binder that knows how to handle Enums. I found an excellent article on a possible custom modelBinder for Enums: http://eliasbland.wordpress.com/2009/08/08/enumeration-model-binder-for-asp-net-mvc/. I've since implemented that modelBinder and registered it in my global.asax: ModelBinders.Binders[typeof (MyEnum)] = new EnumBinder<MyEnum>(MyEnum.MyDefault); For some reason, the EnumBinder< isn't being called when the model I'm binding to has MyEnum. I have a breakpoint in the .BindModel() method and it never break. Also, my model hasn't changed after modelBinding. Have I done everything? What am I missing here?

  • Is there a nice way of having static generic parameters is Java?

    - by Chris
    Hello, recently I'm writing some functions that I take from Haskell and translate into Java. One of the main problems I have is I cannot easily create a static property with a generic type. Let me explain by a little example... // An interface to implement functions public interface Func<P, R> { public R apply(P p); } // What I want to do... (incorrect in Java) public class ... { public static <T> Func<T, T> identity = new Func<T, T>() { public T apply(T p) { return p; } } } // What I do right now public class ... { private static Func<Object, Object> identity = new Func<Object, Object>() { public Object apply(Object p) { return p; } } @SuppressWarnings("unchecked") public static <T> Func<T, T> getIdentity() { return (Func<T, T>)identity; } } Are there any easier ways to do something like that? What kind of problems might arise if the syntax I used would be valid?

  • Rails nested association issue

    - by Ben Langfeld
    Ok, so I'm new to both Ruby and Rails and I'm trying to do what I believe is called a nested association (please correct me if this is the wrong terminology). I currently have a User model and a Domains model and I have many to many associations setup (using has_many :through) between the two, and this works fine. I now want to extend this to allow for a single role per domain per user (eg User1 is a member of Domain1 and has the role "Admin"). I have setup a Roles model with a single field (name:string) and have created three roles. I have also added a role_id column to the join table (memberships). I expected (and this is probably the issue) to be able to just use user1 = User.find(1) user1.domains.first => <some domain object> user1.domains.first.role => <some role object> but this returns a method not defined error. Can anyone tell me what I'm failing to grasp here? My model classes can be seen at http://gist.github.com/388200

  • Conflict with @Html.LabelFor and W3C Validator?

    - by Tyler
    I have a model that I am using to present an index of a model from a database and have given a display name to some of the rows that may need spaces in them, (I.e. "weekstarting" in a db would be given a display name of "Week Starting"). So I set the display name for my model like this: [DisplayName("Week Starting")] public DateTime WeekStarting { get; set; } and then in the table headers for my table I use the following line of code to display the field name using its given display name: @Html.LabelFor(x => x.First().WeekStarting) The above all works fine. But I am using the W3C validator and it is giving me the following error for the example I have given: The for attribute of the label element must refer to a form control. Forgive me if it is obvious but what am I doing wrong here? I am not using a form I am simply displaying an index of items in a table. I have tried to look for an answer and saw someone suggest that the form controls being referred to need ids (even though I'm not using a form) but this would not be applicable in this instance because if I tried to set an id in the index it would be duplicated with each item in the index: foreach (var item in Model.Tbms) { <tr><td>@item.value</td><tr>.... would be repeated for each item, and also unsure where I would put the id in any case, the td? } Or is there a better way to label the field header, with my preferred display name in the first place? I guess I could just swap @Html.LabelFor... for Hard code field name but do I have to?

  • How to set title and class in the HTML for the options of a ModelChoiceField?

    - by celopes
    I have a model class MyModel(models.Model): name = models.CharField(max_length=80, unique=True) parent = models.ForeignKey('self', null=True, blank=True) I want to render a ModelChoiceField for that model that looks like: <select name="mymodel" id="id_mymodel"> <option value="1" title="Value 1" class="">Value 1</option> <option value="2" title="Value 2" class="Value 1">Value 2</option> </select> The differences between this output and the default output for a ModelChoiceField are the title and class elements in the OPTION tag. They don't exist in ModelChoiceField's default output. For my purposes: The title element is supposed to be the Option Name. The class element is supposed to be self.parent.name. (this is my problem) So, in the HTML snippet above, Value 1 has no parent and Value 2 has a parent of Value 1. What is the best mechanism to change ModelChoiceField's default HTML output? EDIT: I understand how to create a new Widget for rendering HTML. The problem is how to render a value from the underlying model in each of the options.

  • Quick question regarding MVC framework for a java game

    - by Jason
    I have a question regarding the use of the MVC framework for a blackjack game im writing in java. As I understand, my model would be a class that stores the state of the game, and more specifically, each players hand. Within the model class, I would have an array of listeners, which would be notified each time the game state changes (ie a player has drawn a new card). These listeners would be my viewer, which is the class that handles the display of the game. This class would implement the ActionListener interface, and each time the model changes, it would call/"notify" my viewer's actionPerformed method. My question is as follows: I intend to have two JPanels, each devoted to displaying the respective player's hand. As a player draws a new card, a new ImageIcon would be added to the panel. My question is how would the viewer class know what card has been added to the player's hand? I suppose I could store the player's hand before a notify event, and then upon the notification event, compare the new state with the old, to find out what has changed. I'm a complete novice here, so I could be completely wrong, but it seems a bit tedious to do this. Is there a more efficient/common way of detecting what has changed in the model between the before and after state? Another solution would be to redraw the entire panel each time the notification occurs? Would this be a better idea?

  • C# properties: How are they instantiated?

    - by Pedery
    Hi! This might be a pretty straightforward question, but I'm trying to understand some of the internal workings of the compilation. Very simply put, imagine an arbitrary object being instantiated. This object is then allocated on the heap. The object has a property of type PointF (which is value type), with a get and a set method. Imagine the get and the set method containing a few calculations for doing their work. How and where (stack/heap) and when is this code instantiated? This is the background for this question: I'm writing get and set methods for an object and these methods need to be accessed very frequently. The get and set code in itself is rather massive so I feared that in a worst case scenario the methods would be instantiated as an object or a value type with all internal code for every access of the property. On the other hand the code is probably instantiated when the main object is created and the CPU is simply told to jmp to the property code start. Anyway, this is what I want to have clarified.

  • Calling a register method from 2 or more controllers best practice

    I don't want to repeat myself. That is, I don't want the same code in two different controllers. I always start from a default mvc5 web app project. That project has a Register ActionMethod in an AccountController: // // GET: /Account/Register [AllowAnonymous] public ActionResult Register() { return View(); } // // POST: /Account/Register [HttpPost] [AllowAnonymous] [ValidateAntiForgeryToken] public async Task<ActionResult> Register(RegisterViewModel model) { if (ModelState.IsValid) { var user = new ApplicationUser() { UserName = model.UserName }; var result = await UserManager.CreateAsync(user, model.Password); if (result.Succeeded) { await SignInAsync(user, isPersistent: false); return RedirectToAction("Index", "Home"); } else { AddErrors(result); } } // If we got this far, something failed, redisplay form return View(model); } Say I have a CampaignController and I want to register a user when he/she is on that page, fills out his/her username and pass and clicks the send form/submit button. What is the best thing to do in the ActionMethod of that form/controller? Yes, I want to have the registerform in two or more places. What is the best way to accomplish this in mvc 5?

  • Agile web development with rails

    - by Steve
    Hi.. This code is from the agile web development with rails book.. I don't understand this part of the code... User is a model which has name,hashed_password,salt as its fields. But in the code they are mentioning about password and password confirmation, while there are no such fields in the model. Model has only hashed_password. I am sure mistake is with me. Please clear this for me :) User Model has name,hashed_password,salt. All the fields are strings require 'digest/sha1' class User < ActiveRecord::Base validates_presence_of :name validates_uniqueness_of :name attr_accessor :password_confirmation validates_confirmation_of :password validate :password_non_blank def self.authenticate(name, password) user = self.find_by_name(name) if user expected_password = encrypted_password(password, user.salt) if user.hashed_password != expected_password user = nil end end user end def password @password end def password=(pwd) @password = pwd return if pwd.blank? create_new_salt self.hashed_password = User.encrypted_password(self.password, self.salt) end private def password_non_blank errors.add(:password,"Missing password")if hashed_password.blank? end def create_new_salt self.salt = self.object_id.to_s + rand.to_s end def self.encrypted_password(password, salt) string_to_hash = password + "wibble" + salt Digest::SHA1.hexdigest(string_to_hash) end end

  • jquery, attaching objects (instead of string attribute) to an element

    - by binaryLV
    Hi! I'm trying to build DOM with jQuery and fill it with data that is received with AJAX (data type = json). I'd like to also store this data as an object, attached to a specific DOM element. Does jQuery provide any method for this? The reason I want to do it is because only part of data is initially displayed; other data might be needed later, depending on user actions. I tried using attr(), but it stores a string "[object Object]" instead of an actual object: var div = $('<div/>'); div.attr('foo', {bar: 'foobar'}); alert(div.attr('foo')); // gives "[object Object]" alert(typeof div.attr('foo')); // gives "string" alert(div.attr('foo').bar); // gives "undefined" Another way to do this would be by "bypassing" jQuery (div[0].foo = {bar: 'foobar'};), though this seems to be a "dirty workaround", if jQuery happens to already support attaching objects. Any ideas? Thanks in advance!
