  • Sharing business logic between server-side and client-side of web application?

    - by thoughtpunch
    Quick question concerning shared code/logic in back and front ends of a web application. I have a web application (Rails + heavy JS) that parses metadata from HTML pages fetched via a user supplied URL (think Pinterest or Instapaper). Currently this processing takes place exclusively on the client-side. The code that fetches the URL and parses the DOM is in a fairly large set of JS scripts in our Rails app. Occasionally want to do this processing on the server-side of the app. For example, what if a user supplied a URL but they have JS disabled or have a non-standard compliant browser, etc. Ideally I'd like to be able to process these URLS in Ruby on the back-end (in asynchronous background jobs perhaps) using the same logic that our JS parsers use WITHOUT porting the JS to Ruby. I've looked at systems that allow you to execute JS scripts in the backend like execjs as well as Ruby-to-Javascript compilers like OpalRB that would hopefully allow "write-once, execute many", but I'm not sure that either is the right decision. Whats the best way to avoid business logic duplication for apps that need to do both client-side and server-side processing of similar data?

  • Correct way to inject dependencies in Business logic service?

    - by Sri Harsha Velicheti
    Currently the structure of my application is as below Web App -- WCF Service (just a facade) -- Business Logic Services -- Repository - Entity Framework Datacontext Now each of my Business logic service is dependent on more than 5 repositories ( I have interfaces defined for all the repos) and I am doing a Constructor injection right now(poor mans DI instead of using a proper IOC as it was determined that it would be a overkill for our project). Repositories have references to EF datacontexts. Now some of the methods in the Business logic service require only one of the 5 repositories, so If I need to call that method I would end up instantiating a Service which will instatiate all 5 repositories which is a waste. An example: public class SomeService : ISomeService { public(IFirstRepository repo1, ISecondRepository repo2, IThirdRepository repo3) {} // My DoSomething method depends only on repo1 and doesn't use repo2 and repo3 public DoSomething() { //uses repo1 to do some stuff, doesn't use repo2 and repo3 } public DoSomething2() { //uses repo2 and repo3 to do something, doesn't require repo1 } public DoSomething3() { //uses repo3 to do something, doesn't require repo1 and repo2 } } Now if my I have to use DoSomething method on SomeService I end up creating both IFirstRepository,ISecondRepository and IThirdRepository but using only IFirstRepository, now this is bugging me, I can seem to accept that I am un-necessarily creating repositories and not using them. Is this a correct design? Are there any better alternatives? Should I be looking at Lazy instantiation Lazy<T> ?

  • FluentNHibernate Unit Of Work / Repository Design Pattern Questions

    - by Echiban
    Hi all, I think I am at a impasse here. I have an application I built from scratch using FluentNHibernate (ORM) / SQLite (file db). I have decided to implement the Unit of Work and Repository Design pattern. I am at a point where I need to think about the end game, which will start as a WPF windows app (using MVVM) and eventually implement web services / ASP.Net as UI. Now I already created domain objects (entities) for ORM. And now I don't know how should I use it outside of ORM. Questions about it include: Should I use ORM entity objects directly as models in MVVM? If yes, do I put business logic (such as certain values must be positive and be greater than another Property) in those entity objects? It is certainly the simpler approach, and one I am leaning right now. However, will there be gotchas that would trash this plan? If the answer above is no, do I then create a new set of classes to implement business logic and use those as Models in MVVM? How would I deal with the transition between model objects and entity objects? I guess a type converter implementation would work well here. Now I followed this well written article to implement the Unit Of Work pattern. However, due to the fact that I am using FluentNHibernate instead of NHibernate, I had to bastardize the implementation of UnitOfWorkFactory. Here's my implementation: using System; using FluentNHibernate.Cfg; using FluentNHibernate.Cfg.Db; using NHibernate; using NHibernate.Cfg; using NHibernate.Tool.hbm2ddl; namespace ELau.BlindsManagement.Business { public class UnitOfWorkFactory : IUnitOfWorkFactory { private static readonly string DbFilename; private static Configuration _configuration; private static ISession _currentSession; private ISessionFactory _sessionFactory; static UnitOfWorkFactory() { // arbitrary default filename DbFilename = "defaultBlindsDb.db3"; } internal UnitOfWorkFactory() { } #region IUnitOfWorkFactory Members public ISession CurrentSession { get { if (_currentSession == null) { throw new InvalidOperationException(ExceptionStringTable.Generic_NotInUnitOfWork); } return _currentSession; } set { _currentSession = value; } } public ISessionFactory SessionFactory { get { if (_sessionFactory == null) { _sessionFactory = BuildSessionFactory(); } return _sessionFactory; } } public Configuration Configuration { get { if (_configuration == null) { Fluently.Configure().ExposeConfiguration(c => _configuration = c); } return _configuration; } } public IUnitOfWork Create() { ISession session = CreateSession(); session.FlushMode = FlushMode.Commit; _currentSession = session; return new UnitOfWorkImplementor(this, session); } public void DisposeUnitOfWork(UnitOfWorkImplementor adapter) { CurrentSession = null; UnitOfWork.DisposeUnitOfWork(adapter); } #endregion public ISession CreateSession() { return SessionFactory.OpenSession(); } public IStatelessSession CreateStatelessSession() { return SessionFactory.OpenStatelessSession(); } private static ISessionFactory BuildSessionFactory() { ISessionFactory result = Fluently.Configure() .Database( SQLiteConfiguration.Standard .UsingFile(DbFilename) ) .Mappings(m => m.FluentMappings.AddFromAssemblyOf<UnitOfWorkFactory>()) .ExposeConfiguration(BuildSchema) .BuildSessionFactory(); return result; } private static void BuildSchema(Configuration config) { // this NHibernate tool takes a configuration (with mapping info in) // and exports a database schema from it _configuration = config; new SchemaExport(_configuration).Create(false, true); } } } I know that this implementation is flawed because a few tests pass when run individually, but when all tests are run, it would fail for some unknown reason. Whoever wants to help me out with this one, given its complexity, please contact me by private message. I am willing to send some $$$ by Paypal to someone who can address the issue and provide solid explanation. I am new to ORM, so any assistance is appreciated.

  • JQuery Tools Overlay for modal dialog broken under IE8

    - by Gary McGill
    I've been developing a website that has several modal dialog boxes. I've been using jQuery Tools Overlay for the dialog boxes. However, I've just discovered that it doesn't seem to work properly on IE8. In Chrome (and I presume other browsers), the dialog is highlighted by darkening the rest of the page "below" it, but on IE8 the page "below" is obliterated - all you get is the dialog on a black background. This appears to be nothing to do with the way I've configured it - the same problem is evident on the jQuery Tools website itself. If you click the link above and then click one of the two buttons headed "For User Interactions", then you'll see what I mean. What's the deal? Does it simply not support IE8? If so, (a) grrrr... and (b) what else should I use?

  • Moq broken? Not working with .net 4.0

    - by vdh_ant
    Hi guys I am receiving the following exception when trying to run my unit tests using .net 4.0 under VS2010 with moq 3.1. Attempt by security transparent method 'SPPD.Backend.DataAccess.Test.Specs_for_Core.When_using_base.Can_create_mapper()' to access security critical method 'Microsoft.VisualStudio.TestTools.UnitTesting.Assert.IsNotNull(System.Object)' failed. Assembly 'SPPD.Backend.DataAccess.Test, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' is marked with the AllowPartiallyTrustedCallersAttribute, and uses the level 2 security transparency model. Level 2 transparency causes all methods in AllowPartiallyTrustedCallers assemblies to become security transparent by default, which may be the cause of this exception. The test I am running is really straight forward and looks something like the following: [TestMethod] public void Can_create_mapper() { this.SetupTest(); var mockMapper = new Moq.Mock<IMapper>().Object; this._Resolver.Setup(x => x.Resolve<IMapper>()).Returns(mockMapper).Verifiable(); var testBaseDa = new TestBaseDa(); var result = testBaseDa.TestCreateMapper<IMapper>(); Assert.IsNotNull(result); //<<< THROWS EXCEPTION HERE Assert.AreSame(mockMapper, result); this._Resolver.Verify(); } I have no idea what this means and I have been looking around and have found very little on the topic. The closest reference I have found is this http://dotnetzip.codeplex.com/Thread/View.aspx?ThreadId=80274 but its not very clear on what they did to fix it... Anyone got any ideas?

  • Mavericks system Ruby and gem broken

    - by T1000
    When I tried to run ruby -v or gem -v (or any other command), I get: dyld: lazy symbol binding failed: Symbol not found: _ruby_run Referenced from: /usr/local/bin/ruby Expected in: /usr/lib/libruby.dylib dyld: Symbol not found: _ruby_run Referenced from: /usr/local/bin/ruby Expected in: /usr/lib/libruby.dylib This is after I ran rvm system to temporally switch to the system default Ruby. RVM is working fine, but I have a special need to install a gem to the system Ruby and I can't because of this problem. Does anyone know why? It seems to be some kind of link problem to Ruby, but I'm don't know how to solve this. I ran which ruby and it's at this point located in "/usr/local/bin/ruby". I checked the Ruby in "/usr/lib/" and it's pointing to my system Ruby: "../../System/Library/Frameworks/Ruby.framework/Versions/Current/usr/lib/ruby" Any help would be appreciated.

  • SQL Reporting Services - Subreports Broken into multiple columns

    - by devin
    Hi, I inherited an SQL Reporting Services .rdl project from somebody and need help fixing some functionality. In each row of the report, there is a subreport. In order to save space the subreport is divided into 3. Such that in each row of the report, it splits the data of the subreport into 3 smaller tables. Right now, it fills these 3 subreports horizontally. (ie. if the result has 9 values, the first subtable will have 1, 4 & 7, the second subtable will have 2, 5 & 8, etc) Is there a way to have it fill the subtables vertically? (ie. the first subtable would have 1,2 & 3) Thanks!

  • SQL SERVER – Implementing IF … THEN in SQL SERVER with CASE Statements

    - by Pinal Dave
    Here is the question I received the other day in email. “I have business logic in my .net code and we use lots of IF … ELSE logic in our code. I want to move the logic to Stored Procedure. How do I convert the logic of the IF…ELSE to T-SQL. Please help.” I have previously received this answer few times. As data grows the performance problems grows more as well. Here is the how you can convert the logic of IF…ELSE in to CASE statement of SQL Server. Here are few of the examples: Example 1: If you are logic is as following: IF -1 < 1 THEN ‘TRUE’ ELSE ‘FALSE’ You can just use CASE statement as follows: -- SQL Server 2008 and earlier version solution SELECT CASE WHEN -1 < 1 THEN 'TRUE' ELSE 'FALSE' END AS Result GO -- SQL Server 2012 solution SELECT IIF ( -1 < 1, 'TRUE', 'FALSE' ) AS Result; GO If you are interested further about how IIF of SQL Server 2012 works read the blog post which I have written earlier this year . Well, in our example the condition which we have used is pretty simple but in the real world the logic can very complex. Let us see two different methods of how we an do CASE statement when we have logic based on the column of the table. Example 2: If you are logic is as following: IF BusinessEntityID < 10 THEN FirstName ELSE IF BusinessEntityID > 10 THEN PersonType FROM Person.Person p You can convert the same in the T-SQL as follows: SELECT CASE WHEN BusinessEntityID < 10 THEN FirstName WHEN BusinessEntityID > 10 THEN PersonType END AS Col, BusinessEntityID, Title, PersonType FROM Person.Person p However, if your logic is based on multiple column and conditions are complicated, you can follow the example 3. Example 3: If you are logic is as following: IF BusinessEntityID < 10 THEN FirstName ELSE IF BusinessEntityID > 10 AND Title IS NOT NULL THEN PersonType ELSE IF Title = 'Mr.' THEN 'Mister' ELSE 'No Idea' FROM Person.Person p You can convert the same in the T-SQL as follows: SELECT CASE WHEN BusinessEntityID < 10 THEN FirstName WHEN BusinessEntityID > 10 AND Title IS NOT NULL THEN PersonType WHEN Title = 'Mr.' THEN 'Mister' ELSE 'No Idea' END AS Col, BusinessEntityID, Title, PersonType FROM Person.Person p I hope this solution is good enough to convert the IF…ELSE logic to CASE Statement in SQL Server. Let me know if you need further information about the same.

  • Auto-Insert double quotes for HTML attributes broken

    - by ScottS
    In VS2008, it used to be that whenever I was typing an html attribute in an .aspx page when I hit '=' a pair of double quotes was automatically inserted and the cursor placed inside them. I guess I've changed a setting, but I don't know what to change to get that functionality back. I am using Resharper if it makes a difference.

  • Facebook multi-friend-selector + new javascript API = BROKEN ?

    - by Simon_Weaver
    I am using the fb:serverfbml tag to render a multi-friend-selector inside an IFrame. I am using the new javascript API. I have been trying ALL DAY to get it working. When I click on the underlines 'selected' link (to filter by the selected friends) the whole page refreshes and the selected friends disappear. Does the multi-friend-selector just not work with the javascript API? <fb:serverfbml> <script type="text/fbml"> <fb:request-form action="http://apps.facebook.com/rollingrazor/" target="_top" method="POST" invite="true" type="Blah blah blah" content="Blah blah! &lt;fb:req-choice url=&quot;http://apps.facebook.com/rollingrazor/&quot; label=&quot;Let me check my friends&quot; /&gt;"> <fb:multi-friend-selector showborder="false" actiontext="Invite your friends" rows="5" cols="5" bypass="cancel" target="_top" /> </fb:request-form> </script> </fb:serverfbml> <div id="fb-root"></div> <script> window.fbAsyncInit = function () { FB.init({ appId: 'xxxxxxx', status: true, cookie: true, xfbml: true }); }; (function () { var e = document.createElement('script'); e.async = true; e.src = document.location.protocol + '//connect.facebook.net/en_US/all.js'; document.getElementById('fb-root').appendChild(e); } ()); </script> Can someone give me a working example using new javascript API with a multi-friend-selector?

  • Is NUnit broken with Windows7 for C++/CLI?

    - by Andy Dent
    NUnit is failing in C++/CLI with a System.IO.FileNotFoundException. I have tried my own freshly-created project, the C++/CLI sample included with NUnit and the one from CodeProject How to use NUnit to test native C++ code using Visual Studio 2008sp1 with NUnit 2.5.5 as well as 2.4.8. I installed 2.4.8 just on C:\ in case there was something weird about paths with spaces such as Program Files (x86). I have no problems with a C# sample using NUnit. in NUnit GUI, all of these C++/CLI projects encounter the same problem, on attempting to open the projects. I'd really like to use NUnit but for now have had to go back to standard Microsoft tests System.IO.FileNotFoundException...

  • iPhone hitTest broken after rotation

    - by Adam
    Hi all, I have a UIView that contains a number of CALayer subclasses. I am using the following code to detect which layer a touch event corresponds to: - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { UITouch *touch = [touches anyObject]; CGPoint touchPoint = [touch locationInView:self]; NSLog(@"%@,%@",NSStringFromCGPoint(point),[self.layer hitTest:point].name); } This works fine until the device is rotated. When the device is rotated all current layers are removed from the superlayer, and new CALayers are created to fit the new orientation. The new layers are correctly inserted and viewable in the correct orientation. After the rotation the hitTest method consistently returns nil when clearly clicking on the newly created layers and registers for locations of layers which are incorrect. The coordinates of the hit test are correct, but no layers are found. Am I missing a function call or something after handling the rotation? Cheers, Adam

  • Many to Many Logic in ASP.NET MVC

    - by Jonathan Stowell
    Hi All, I will restrict this to the three tables I am trying to work with Problem, Communications, and ProbComms. The scenario is that a Student may have many Problems concurrently which may affect their studies. Lecturers may have future communications with a student after an initial problem is logged, however as a Student may have multiple Problems the Lecturer may decide that the discussion they had is related to more than one Problem. Here is a screenshot of the LINQ representation of my DB: LINQ Screenshot At the moment in my StudentController I have a StudentFormViewModel Class: // //ViewModel Class public class StudentFormViewModel { IProbCommRepository probCommRepository; // Properties public Student Student { get; private set; } public IEnumerable<ProbComm> ProbComm { get; private set; } // // Dependency Injection enabled constructors public StudentFormViewModel(Student student, IEnumerable<ProbComm> probComm) : this(new ProbCommRepository()) { this.Student = student; this.ProbComm = probComm; } public StudentFormViewModel(IProbCommRepository pRepository) { probCommRepository = pRepository; } } When I go to the Students Detail Page this runs: public ActionResult Details(string id) { StudentFormViewModel viewdata = new StudentFormViewModel(studentRepository.GetStudent(id), probCommRepository.FindAllProblemComms(id)); if (viewdata == null) return View("NotFound"); else return View(viewdata); } The GetStudent works fine and returns an instance of the student to output on the page, below the student I output all problems logged against them, but underneath these problems I want to show the communications related to the Problem. The LINQ I am using for ProbComms is This is located in the Model class ProbCommRepository, and accessed via a IProbCommRepository interface: public IQueryable<ProbComm> FindAllProblemComms(string studentEmail) { return (from p in db.ProbComms where p.Problem.StudentEmail.Equals(studentEmail) orderby p.Problem.ProblemDateTime select p); } However for example if I have this data in the ProbComms table: ProblemID CommunicationID 1 1 1 2 The query returns two rows so I assume I somehow have to groupby Problem or ProblemID but I am not too sure how to do this with the way I have built things as the return type has to be ProbComm for the query as thats what Model class its located in. When it comes to the view the Details.aspx calls two partial views each passing the relevant view data through, StudentDetails works fine page: <%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<MitigatingCircumstances.Controllers.StudentFormViewModel>" %> <% Html.RenderPartial("StudentDetails", this.ViewData.Model.Student); %> <% Html.RenderPartial("StudentProblems", this.ViewData.Model.ProbComm); %> StudentProblems uses a foreach loop to loop through records in the Model and I am trying another foreach loop to output the communication details: <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<IEnumerable<MitigatingCircumstances.Models.ProbComm>>" %> <script type="text/javascript" language="javascript"> $(document).ready(function() { $("DIV.ContainerPanel > DIV.collapsePanelHeader > DIV.ArrowExpand").toggle( function() { $(this).parent().next("div.Content").show("slow"); $(this).attr("class", "ArrowClose"); }, function() { $(this).parent().next("div.Content").hide("slow"); $(this).attr("class", "ArrowExpand"); }); }); </script> <div class="studentProblems"> <% var i = 0; foreach (var item in Model) { %> <div id="ContainerPanel<%= i = i + 1 %>" class="ContainerPanel"> <div id="header<%= i = i + 1 %>" class="collapsePanelHeader"> <div id="dvHeaderText<%= i = i + 1 %>" class="HeaderContent"><%= Html.Encode(String.Format("{0:dd/MM/yyyy}", item.Problem.ProblemDateTime))%></div> <div id="dvArrow<%= i = i + 1 %>" class="ArrowExpand"></div> </div> <div id="dvContent<%= i = i + 1 %>" class="Content" style="display: none"> <p> Type: <%= Html.Encode(item.Problem.CommunicationType.TypeName) %> </p> <p> Problem Outline: <%= Html.Encode(item.Problem.ProblemOutline)%> </p> <p> Mitigating Circumstance Form: <%= Html.Encode(item.Problem.MCF)%> </p> <p> Mitigating Circumstance Level: <%= Html.Encode(item.Problem.MitigatingCircumstanceLevel.MCLevel)%> </p> <p> Absent From: <%= Html.Encode(String.Format("{0:g}", item.Problem.AbsentFrom))%> </p> <p> Absent Until: <%= Html.Encode(String.Format("{0:g}", item.Problem.AbsentUntil))%> </p> <p> Requested Follow Up: <%= Html.Encode(String.Format("{0:g}", item.Problem.RequestedFollowUp))%> </p> <p>Problem Communications</p> <% foreach (var comm in Model) { %> <p> <% if (item.Problem.ProblemID == comm.ProblemID) { %> <%= Html.Encode(comm.ProblemCommunication.CommunicationOutline)%> <% } %> </p> <% } %> </div> </div> <br /> <% } %> </div> The issue is that using the example data before the Model has two records for the same problem as there are two communications for that problem, therefore duplicating the output. Any help with this would be gratefully appreciated. Thanks, Jon

  • appstats broken filename in callstack

If your request handlers modify sys.path, you must make the same modifications to sys.path in appengine_config.py so the Appstats web interface can see all files. Actually I'm using appengine_django and two path was inserted to sys.path. I did it same again at appengine_django.py but also failed. Maybe some custom setting with appengine_config.py can solve this problem but doesn't figure out how to fix it. What can I do?

  • Recovering Broken Connections In A Peer to Peer Network

    - by peter
    Hi All, I am implementing a peer to peer network using WCF NetPeerTcpBinding connections. I am using a central server which itself overrides the class CustomPeerResolverService. All this service does is register peers, and publish information about the peers to each other. On my server application I can visibly see which peers are currently connected on the GUI. My question is, each peer has a TCP connection to the server. When I unplug my network connection all connections to this server are severed. When the network comes back online those connections to the server are not re-established. What do I need to do to make sure they are re-established? Here is what each of the peer to peer bindings look like on the peers. <netPeerTcpBinding> <binding name="PeerTcpConfig" port="0"> <security mode="None"></security> <resolver mode="Custom"> <custom address="net.tcp://127.0.0.1/GlobalStoreAPIServer" binding="netTcpBinding" bindingConfiguration="TcpConfig"> </custom> </resolver> </binding> </netPeerTcpBinding> So what that means is that my server has an endpoint at 'net.tcp://127.0.0.1/GlobalStoreAPIServer'

  • Playing videos in UIWebView broken in iOS4?

    - by rforte
    I have an app that's worked since version 2.0 of the SDK where I create and add a UIWebView and then load the URL of an .mov to play a movie. Ever since the early version of the 4.0 beta up until the 4.0 GM this has stopped working. When I load a movie now I get the following error: :Plug-in handled load" and the movie never displays. Is this a known issue? Am I doing something wrong in 4.0?

  • Crystal report subreport parameter autobinding logic feeds duplicate parameters to different subrepo

    - by quillbreaker
    I have a report, and I place the same subreport within the footer twice. The report has three parameters and the subreport has four parameters. When I try to run the report through the report designer, it prompts me for seven parameters instead of the eleven I was hoping for. It prompts for one set of parameters for the subreport (with a default prompt of @parameter(subreport.rpt)/@parameter(subreport.rpt - 01), and passes the same set of parameters to both subreports. This isn't what I want the report to do. Furthermore, if I look at 'show report parameters', it does show eleven parameters, with the same value for both subreport parameter sets. So it knows that it's two different subreports, but it does not want to let me enter it that way. Is there some way I can make crystal designer realize that it should take different values for each subreport? The only solution I've found is to add 8 more parameters, one for each subreport / subreport parameter combination, and bind them individually. It works, but it feels like a workaround. Does anyone have a better solution?

  • xslt broken: pattern does not match

What is wrong with Package/Participants/Participant ? What do I miss here? Thanks a lot!

  • Broken tables in RichTextBox control (word wrap)

    - by Ben Robbins
    We are having problems with the Windows.Forms.RichTextBox control in Visual Studio 2008. We are trying to display text supplied as an RTF file by a 3rd party in a windows forms application (.NET 3.5). In this RTF text file there are tables, which contain text that spans multiple lines. The RTF file displays correctly when opened with either WordPad or Word 2003. However, when we load the RTF file into the RichTextBox control, or copy & paste the whole text (including the table) into the control, the table does not display correctly - the cells are only single line, without wrapping. Here are links to images showing the exact problem: Correctly displayed in WordPad Incorrectly displayed in RichTextBox control I have googled for solutions and 3rd party .net RTF controls without success. I have found this exact problem asked on another forum without an answer (in fact that's where the link to the images come from) so I'm hoping stack overflow does better ;-) My preferred solution would be to use code or a 3rd party control that can correctly render the RTF. However, I suspect the problem is that the RichTextBox control only supports a subset of the full RTF spec, so another option would be to modify the RTF directly to remove the unsupported control codes or otherwise fix the RTF file itself (in which case any information as to what control codes need to be removed or modified would be a huge help).
