  • Zend without Database

    - by dbemerlin
    Hi, i googled for an hour now but maybe my Google-Fu is just too weak, i couldn't find a solution. I want to create an application that queries a service via JSON requests (all data and backend/business logic is stored in the service). With plain PHP it's simple enough since i just make a curl request, json_decode the result and get what i need. This already works quite well. A request might look like this: Call http://service-host/userlist with body: {"logintoken": "123456-1234-5678-901234"} Get Result: { "status": "Ok", "userlist":[ {"name": "foo", "id": 1}, {"name": "bar", "id": 2} ] } Now we want to get that into the Zend Framework since it's a hobby project and we want to learn about Zend. The problem is that all information i could find use a Database. Is there even a way to create a Zend Project that does not use a Database? And how can i write a model that represents the actions instead of objects and object-relations?

  • JPA DAO integration test not throwing exception when duplicate object saved?

    - by HDave
    I am in the process of unit testing a DAO built with Spring/JPA and Hibernate as the provider. Prior to running the test, DBUnit inserted a User record with username "poweruser" -- username is the primary key in the users table. Here is the integration test method: @Test @ExpectedException(EntityExistsException.class) public void save_UserTestDataSaveUserWithPreExistingId_EntityExistsException() { User newUser = new UserImpl("poweruser"); newUser.setEmail("[email protected]"); newUser.setFirstName("New"); newUser.setLastName("User"); newUser.setPassword("secret"); dao.persist(newUser); } I have verified that the record is in the database at the start of this method. Not sure if this is relevant, but if I do a dao.flush() at the end of this method I get the following exception: javax.persistence.PersistenceException: org.hibernate.exception.ConstraintViolationException: Could not execute JDBC batch update

  • Is there anyway to bring web @Context into JUnit (CXF+Spring)

    - by Sudheer
    I am trying to create unit test environment to test RESTFul services (cfx+spring) in my dev environemnt. To test RESTFul Services, I require @Context within JUnit test cases. @Context should contain HttpRequest, HttpSession, ServletContext, ServletConfig and all other webserver related information. I have setup the JUnit for the above, but when I run, @Context is coming as null. This could be because there is no webserver running and there is no @Context. I am just doubting whether there is a way to created sample web @Context and pass to JUnit. Any other ideas are welcome to bring web @Context into JUnit test cases. Thank you, Sudheer

  • Testing a (big) collection retrieved from a db

    - by Bas
    I'm currently doing integration testing on a live database and I have the following sql statement: var date = DateTime.Parse("01-01-2010 20:30:00"); var result = datacontext.Repository<IObject>().Where(r => r.DateTime > date).First(); Assert.IsFalse(result.Finished); I need to test if the results retrieved from the statement, where the given date is less then the date of the object, have Finished set to False. I do not know how many results I get back and currently I'm getting the first object of the list and check if that object has Finished set to false. I know testing only the first item of the list is not valid testing, as a solution for that I could iterate through the list and check all items on Finished, but putting logic in a Test is kinda going against the concept of writing 'good' tests. So my question is: Does anyone have a good solution of how to properly test the results of this list?

  • How can I utilize or mimic Application OnStart in an HttpModule?

    - by Sailing Judo
    We are trying to remove the global.asax from our many web applications in favor of HttpModules that are in a common code base. This works really well for many application events such as BeginRequest and PostAuthentication, but there is no Application Start event exposed in the HttpModule. I can think of a couple of smelly ways to overcome this deficit. For example, I can probably do this: protected virtual void BeginRequest(object sender, EventArgs e) { Log.Debug("Entered BeginRequest..."); var app = HttpContext.Current.Application; var hasBeenSet app["HasBeenExecuted"] == null ? false : true; if(!hasBeenSet) { app.Lock(); // ... do app level code app.Add("HasBeenSet", true); app.Unlock(); } // do regular begin request stuff ... } But this just doesn't smell well to me. What is the best way to invoke some application begin logic without having a global.asax?

  • Drag and drop + custom drawing in Android

    - by Rich
    I am working on something that needed custom drag-and-drop functionality, so I have been subclassing View, doing a bunch of math in response to touch events, and then rendering everything manually through code on the canvas in onDraw. Now, the more functionality I add, the more the code is growing out of control and I find myself writing a ton more code than I would expect to write in a high level environment like Android. Is this how it's done, or am I missing something? If I'm not doing anything fancy in the UI, the framework handles the majority of my interactions. Built-in controls handle the touches and drags, and my code is pretty much limited to business logic and data. Is there a way to leverage the power of some of the UI controls and things like animations while also doing some of it manually in the onDraw canvas? Is there an accepted standard of when to use one or the other (if indeed the two approaches can be mixed)?

  • is this a simple monad example?

    - by zcaudate
    This is my attempt to grok monadic functions after watching http://channel9.msdn.com/Shows/Going+Deep/Brian-Beckman-Dont-fear-the-Monads. h uses bind to compose together two arbitrary functions f and g. What is the unit operator in this case? ;; f :: int - [str] ;; g :: str = [keyword] ;; bind :: [str] - (str - [keyword]) - [keyword] ;; h :: int - [keyword] (defn f [v] (map str (range v))) (defn g [s] (map keyword (repeat 4 s))) (defn bind [l f] (flatten (map f l))) (f 8) ;; = (0 1 2 3 4 5 6 7) (g "s") ;; = (:s :s :s :s) (defn h [v] (bind (f v) g)) (h 9) ;; = (:0 :0 :0 :0 :1 :1 :1 :1 :2 :2 :2 :2 :3 :3 :3 :3 :4 :4 :4 :4 :5 :5 :5 :5)

  • Accessing every child class of parent class in Java

    - by darkie15
    Hi All, I have to implement a logic whereby given a child class, I need to access its parent class and all other child class of that parent class, if any. I did not find any API in Java Reflection which allows us to access all child classes of a parent class. Is there any way to do it? Ex. class B extends class A class C extends class A Now using class B, I can find the superclass by calling getSuperClass(). But is there any way to find all the child classes once I have the parent class i.e. class B and class C?? Regards, darkie

  • Implementing simple business model in Haskell

    - by elmes
    Supose we have a very simple model: Station has at least one Train Train has at least two Stations The model has to allow to check what stations any given train visits and to check what trains visit a particular station. How to model it in Haskell? I am a Haskell newbie, so please correct me: once an object is created, you cannot modify it - you can only make a new object based on that one (~immutability). Am I right? If so, I'll have to create a lot of temporary variables with semi-initialized objects (during deserialization or even in unit tests). Basically what I need is an example of modeling domain classes in Haskell - after reading "Learn you a haskell.." I still have no idea how to use this language.

  • Directory file size calculation - how to make it faster?

    - by Xinxua
    Using C#, I am finding the total size of a directory. The logic is this way : Get the files inside the folder. Sum up the total size. Find if there are sub directories. Then do a recursive search. I tried one another way to do this too : Using FSO (obj.GetFolder(path).Size). There's not much of difference in time in both these approaches. Now the problem is, I have tens of thousands of files in a particular folder and its taking like atleast 2 minute to find the folder size. Also, if I run the program again, it happens very quickly (5 secs). I think the windows is caching the file sizes. Is there any way I can bring down the time taken when I run the program first time??

  • slow php command line performance - is this normal or do I have an install problem?

    - by Frank Schwieterman
    I have a simple PHP app that prints 'hello world'. When I run it from the command line it takes 6 seconds. Is this normal? It seems to take 1 seconds before "hello world" prints, then 5 seconds after. I assume this is overhead of the interpreter. I am running PHP version 5.2.12 on Windows Server 2008 R2. Could this be an install issue, or is it typical? I did a manual install of PHP then added whatever components were needed to run Drupal. The only PHP addon I remember adding was MDB2, CGI support is there too. I am used to a Lua project I run from the command line, hundreds of lines of code that will run in under a second. I have some unit tests I run from the command line, and already with just a few they are very slow. I run them from Netbeans and the tests are still very slow.

  • How to find scrollable elements in DOM using XPath?

    - by ak.
    Basically I need to find all elements on the page that have a scrollbar (vertical or horizontal) How to tell if an element has a scrollbar and can actually be scrolled? I found this code snippet on jsperf. Is it possible to capture the logic behind the code into and XPath expression? Or are there any other ways to check for scrollbars? Added: Just to explain what I'm trying to do: I'm developing extension for Firefox. Basically it introduces Vim-style mouseless shortcuts (I know there is Vimperator and Pentadactyl...). One of the features I'd like to implement is to allow the use to select the container that's scrolled with j/k keys. That's why I need to discover all scrollable elements on any given random page.

  • System.Diagnostics.Debugger.Debug() stopped working

    - by Andrew Miner
    I'm working on a program which uses the System.Diagnostics.Debugger.Break() method to allow the user to set a breakpoint from the command-line. This has worked fine for many weeks now. However, when I was working on fixing a unit test today, I tried to use the debug switch from the command-line, and it didn't work. Here's what I've tried: I've confirmed that the Debug() method is really being called (by putting a System.Console.WriteLine() after it) I've confirmed that the build is still in Debug I've done a clean build I've restarted Product Studio A quick Google search didn't reveal anything, and the API documentation for .Net doesn't mention anything about this function not performing correctly. So... any ideas?

  • Invoicing vs Quoting or Estimating

    - by FreshCode
    If invoices can be voided, should they be used as quotations? I have an Invoices tables that is created from inventory associated with a Job or Order. I could have a Quotes table as a halfway-house between inventory and invoices, but it feels like I would have duplicate data structures and logic just to handle an "Is this a quote?" bit. From a business perspective, quotes are different from invoices: a quote is sent prior to an undertaking and an invoice is sent once it is complete and payment is due, but how to represent this in my repository and model. What is an elegant way to store and manage quotes & invoices in a database? Edit: indicated Job === Order for this particular instance.

  • Rails - how do you create a user index page like stack overflows with multiple tabs whilst keeping t

    - by adam
    On stackoverflow in the users profile area there are many tabs which all display differing information such as questions asked and graphs. Its the same view though and im wondering hows its best to achieve this in rails whilst keeping the controller skinny and logic in the view to a minimum. def index @user = current_user case params[:tab_selected] when "questions" @data = @user.questions when "answers" @sentences = @user.answers else @sentences = @user.questions end respond_to do |format| format.html # index.html.erb nd end but how do i process this in the index view without a load of if and else statments. And if questions and answers are presented differently whats the best way to go about this.

  • Updating or inserting high scores in SQL

    - by Roger Gilbrat
    I've been racking my brain over this for the past few days and I'm not sure it's possible, but figured I ask here. Is it possible for a single SQL statement to update a high score if your score is greater or insert it if your first score? My Score table has a UserID, Level and Score columns and I like it to follow the following logic: If your new score is greater than your last score for this Level, then replace it. If you don't have a score for this Level then add it. If your score for this Level is less than your highest score for this Level then do nothing. Is this possible in a single SQL statement or do I have to use two, one to see if you have a new high score and if so, replace it? Each UserID would have only one score in the table for each Level. I'm using MySQL.

  • Issues with taglibs while using jasmine-maven-plugin to test dojo widgets with templates

    - by user2880454
    I am using jasmine-maven-plugin to run javascript unit tests for my dojo widgets. One of my dojo widgets refers to a html template jsp file with taglibs. When I initialize my dojo widgets, I get the following error: Error: Invalid template: <%@ taglib uri="http://www.springframework.org/security/tags" prefix="sec"% The plugin uses jetty to deploy the scripts to test. I tried including jstl jar into the WEB-INF folder but it doesn't work. I am assuming it's just not DOJO and this taglib issue can occur even with simple js file. I am looking for some clue on why taglibs are not recognized here. If I remove the taglib entries, my tests just work fine.

  • django related_name for field clashes.

    - by Absolute0
    I am getting a field clash in my models: class Visit(models.Model): user = models.ForeignKey(User) visitor = models.ForeignKey(User) Error: One or more models did not validate: profiles.visit: Accessor for field 'user' clashes with related field 'User.visit_set'. Add a related_name argument to the definition for 'user'. profiles.visit: Accessor for field 'visitor' clashes with related field 'User.visit_set'. Add a related_name argument to the definition for 'visitor'. what would be a sensible 'related_field' to use on visitor field? This model basically represents the visits that take place to a particular user's profile. Also should I replace any of the ForeignKey's with a ManyToManyField? The logic is a bit confusing. Edit: This seems to fix it, but I am unsure if its what I want. :) class Visit(models.Model): user = models.ForeignKey(User) visitor = models.ForeignKey(User, related_name='visitors')

  • Must a Language that Implements Monads be Statically Typed?

    - by Morgan Cheng
    I am learning functional programming style. From this link http://channel9.msdn.com/shows/Going+Deep/Brian-Beckman-Dont-fear-the-Monads/, Brian Beckman gave a brilliant introduction about Monad. He mentioned that Monad is about composition of functions so as to address complexity. A Monad includes a unit function that transfers type T to an amplified type M(T); and a Bind function that, given function from T to M(U), transforms type M(T) to another type M(U). (U can be T, but is not necessarily). In my understanding, the language implementing monad should be type-checked statically. Otherwise, type errors cannot be found during compilation and "Complexity" is not controlled. Is my understanding correct?

  • Rails - Active Record :conditions overrides :select

    - by Nick
    I have a fairly large model and I want to retrieve only a select set of fields for each record in order to keep the JSON string I am building small. Using :select with find works great but my key goal is to use conditional logic with an associated model. Is the only way to do this really with a lamda in a named scope? I'm dreading that perhaps unnecessarily but I'd like to understand if there is a way to make the :select work with a condition. This works: @sites = Site.find :all, :select => 'id,foo,bar' When I try this: @sites = Site.find :all, :select => 'id,foo,bar', :include => [:relatedmodel], :conditions => ["relatedmodel.type in (?)", params[:filters]] The condition works but each record includes all of the Site attributes which makes my JSON string way way too large. Thanks for any pointers!

  • Is there a Java equivalent for Ruby on Rails "url_for"?

    - by Oren Ben-Kiki
    I have written something like this pretty easily in C# (string GetUrl(new { controller = "foo", action = "bar", baz = "fnord" }), based on the existing capabilities of the XmlRouteCollection class provided by the ASP.NET MVC framework (why it isn't there out of the box is beyond me; the additional required code was trivial). I am now faced with a JSP project, and I need the same ability: centralize the logic for generating all URLs in one place, based on a list of routing rules. Is there some code somewhere I could reuse/adapt to do this in Java? It seems like a common enough requirement, but google proved surprisingly unhelpful in finding something like this.

  • How do I measure distances in an image?

    - by Ram Bhat
    Let's say we have an image like so Let's say we've already used filters and an edge detection algorithm in this pic. Now my goal is to measure distances (NOT actual distances, distance can be in any arbitrary unit) . eg: How do I find the length of the hall? (until the window) Or the height of the bookshelves? How exactly do you place the "scale" and measure. I'm looking for ideas. However it would help if the answers were in terms of OpenCV.

  • Combining features from other projects in an ASP.NET MVC application

    - by Katie D
    Hello, I am writing an ASP.NET MVC application that combines a set of features from existing applications. The new application is suppose to use UI features and logic created (especially for this purpose) in the existing applications. For that reason I wanted to create in the existing applications some kind of a "blackbox" that I will be able to drop in my new application along with a matching connection string, and it will work independently, binding data on it's own. I thought about using partial views, but I am having trouble with passing the model data to it, since the controller of the new application should not know about the model of the existing applications. I can not use ASP.NET WebForms, since my application should be a "postback-less" application, and ASP.NET AJAX toolkit or frameworks alike are out of the question. Any help would be greatly appreciated. Thank you, Katie
