• Proper way in MVVM to drive visual states.

  - by firoso

  Given a content presenter that can display one of 4 different application pages, and I want to fade/otherwise animate a transition between pages based on view model state. Ideally I'd like to have these all defined within a DataTemplate, and then trigger transitions based on an enum from the view model, so that when some enum representing state changes, the transitions trigger to the appropriate page. Is there a known best practice to handle things like this? Immediately coming to mind is the possibiltiy to use Enter and Exit actions on data triggers to play storyboards, but this definately doesn't use the parts and states model, so I'd like to shy away from that. I've also tried using the DataStateSwitchBehavior from the codeplex Expression project, but found it to be incompatable with the latest builds of WPF 4.0/Blend 4 RC's SDK. Does anyone have any ideas on how to handle this elegantly? I'm using the MVVM-Light framework. Also I'd like to point out that as long as this resides on a DataTemplate in a Resource Dictionary, code-behind is not an option without refactoring.

• Catch PyGTK TreeView reorder

  - by mkotechno

  I have a simple gtk.TreeView with a gtk.ListStore model and set_reorderable(True), I want to catch the signal/event emited when the user reorder through drag&drop the list, but the documentation does not help much: "The application can listen to these changes by connecting to the model's signals" So I tried to connect the model (ListStore) signals... but surprise! ListStore has no signals, so you are dispatched to TreeModel signals, then I tried to connect with the TreeModel "rows-reordered" signal with no lucky. How should I catch the list reorder performed by the user?

• Create a Models Diagram Using Railroad

  - by SeeBees

  Railroad is a great UML tool for Ruby on Rails. It can automatically generate class diagrams of models and controllers. For models, a railroad-generated class diagram shows attributes of each model and the associations between one model and another. A sample diagram can be found here. It is very useful for a developer to see attributes and associations of models. While attributes and associations reveal the inner states and relationships of models, methods specify their behaviours. They are all desirable in a class diagram. I would like railroad to generate a class diagram that also lists methods for models, which will help me to know what each model does. I know methods are displayed in a diagram that is generated for controllers, but I don't see such an option for a diagram of models. Does someone know how to do that with railroad? Or is that possible? Thanks!

• Conditional relation

  - by Lowgain

  I've got a model like this: Stem -id -etc And then I have Stemrelation -stem_id -related_stem_id -active I can get the related stems with the following relations class Stem < ActiveRecord::Base has_many :stemrelations has_many :related_stems, :through => :stemrelations end class Stemrelation < ActiveRecord::Base belongs_to :stem belongs_to :related_stem, :class_name => "Stem", :foreign_key => "related_stem_id" end But now I'd only like to get the active relations. I tried adding this to the Stem model: has_many :active_related, :through => :stemrelations, :source => :related_stem, :conditions => {:active => true} but this gives me an error becasue it tries to check the active flag on the stem model instead of the stemrelation. What do I change here? Thanks!

• Performing AJAX calls on the "new" controller

  - by shmichael

  In my rails app, I want to have a sortable list as part of an object creation. The best practice suggested Railscast adds the acts_as_list plugin and then initiates AJAX calls to update item position. However, AJAX calls won't work on an unsaved model, which is the situation with new. One solution would be to save the model immediately on new and redirect to edit. This would have a nice side effect of persisting any change so the user could resume work should he be interrupted. However, this solution adds the unwanted complexity of saving an invalid model, compromising rails' validation processes. Is there any better way to allow AJAX + validations without going into too much work?

• Ruby on Rails Join Table Associations

  - by Eef

  Hey, I have a Ruby on Rails application setup like so: User Model has_and_belongs_to_many :roles Role Model has_many :transactions has_and_belongs_to_many :users Transaction Model belongs_to :role This means that a join table is used called roles_users and it also means that a user can only see the transactions that have been assigned to them through roles, usage example: user = User.find(1) transactions = user.roles.first.transactions This will return the transactions which are associated with the first role assigned to the user. If a user has 2 roles assigned to them, at the moment to get the transactions associated with the second role I would do: transactions = user.roles.last.transactions I am basically trying to figure out a way to setup an association so I can grab the user's transactions via something like this based on the roles defined in the association between the user and roles: user = User.find(1) transactions = user.transactions I am not sure if this is possible? I hope you understand what I am trying to do.

• Needing to copy properties before validation

  - by Mikael

  I have a farily complex model needing to be validated, the problem is that this model is used on two different places, one where you register your customer and one where you simply add addresses. Some fields on the address are simply not visible on the register customer form. So when i check if ModelState.IsValid i get false of course since eg. the name is not entered on the billing address, but it is on the customer. That is why i want to before validation occurs, copy a couple of fields to the model, and then validate. I am somewhat lost though and i need help. My action looks something like this: public ActionResult Register(WebCustomer customer) { customer.CopyProperties(); if(TryUpdateModel(customer)) { ... } ... But it always returns false, and ModelState.IsValid continues to be false.

• How to organize asp.net mvc project (using entity framework) and a corresponding database project?

  - by Bernie

  I recently switched to vs2010 and am experimenting with asp.net MVC2. I am building a simple website and use the entity framework to design the data model. From the .edmx file, I generate the database tables. After a few iterations, I decided that it would be nice to have version control of the database schema as well, and therefore I added a database project into which I imported the script that is generated from the datamodel. As a result, I have to generate the sql every time that I change the model and redo the import. The database project automatically updates the database. Although the manual steps to generate the sql and the import are annoying, this works pretty well, until I wanted to add the standard tables for user accounts/authorization etc. I can use the framework tools to add the necessary tables, views etc. to the database, but as I do not want to have them in the .edmx model I end up with a third manual step. Is anybody facing similar issues?

• Entity Framework: Data Centric vs. Object Centric

  - by Eric J.

  I'm having a look at Entity Framework and everything I'm reading takes a data centric approach to explaining EF. By that I mean that the fundamental relationships of the system are first defined in the database and objects are generated that reflect those relationships. Examples Quickstart (Entity Framework) Using Entity Framework entities as business objects? The EF documentation implies that it's not necessary to start from the database layer, e.g. Developers can work with a consistent application object model that can be mapped to various storage schemas When designing a new system (simplified version), I tend to first create a class model, then generate business objects from the model, code business layer stuff that can't be generated, and then worry about persistence (or rather work with a DBA and let him worry about the most efficient persistence strategy). That object centric approach is well supported by ORM technologies such as (n)Hibernate. Is there a reasonable path to an object centric approach with EF? Will I be swimming upstream going that route? Any good starting points?

• Two models, one STI and a Validation

  - by keruilin

  Let's say I have two tables -- Products and Orders. For the sake of simplicity assume that only one product can be purchased at a time so there is no join table like order_items. So the relationship is that Product has many orders, and Order belongs to product. Therefore, product_id is a fk in the Order table. The product table is STI -- with the subclasses being A, B, C. When the user orders subclass Product C, two special validations must be checked on the Order model fields order_details and order_status. These two fields can be nil for all other Product subclasses (ie A and B). In other words, no validation needs to run for these two fields when a user purchases A and B. My question is: How do I write validations (perhaps custom?) in the Order model so that the Order model knows to only run the validations for the two fields -- order_details and order_status -- when Product subclass C is being saved to the orders table?

• Implements an Undo/Redo in MVC

  Hello, I have a Java application and I want to implement an Undo/Redo option. the value that I want to stock and that I want to be able to recover is an integer. My Class Model implements the interface StateEditable and I have to redefine the 2 functions restoreState(Hashtable<?, ?> state) and storeState(Hashtable<Object, Object> state) but I don't know what to put on them. It will be really great if somebody can help me to do that. These are the first lines of my Model class, the value that I want to do an undo/redo on it is value public class Model extends Observable implements StateEditable { private int value = 5; private UndoManager undoRedo = new UndoManager(); final UndoableEditListener editListener = new UndoableEditListener() { public void undoableEditHappened(UndoableEditEvent evt) { undoRedo.addEdit(evt.getEdit()); } }; @Override public void restoreState(Hashtable<?, ?> state) { } @Override public void storeState(Hashtable<Object, Object> state) { } }

  Hi all, I'm a bit new to using emacs for webdevelopment. I am using php-mode and i am happy with it. There is only one issue i have which causes me a lot of problems because of our company's coding style. When i have a function, e.g.: $instance = new Model('foo', 'bar'); And I want to indent it like this: $instance = new Model( 'foo', 'bar' ); Emacs does the following when i insert a newline before the first argument and indents it like this: $instance = new Model( 'foo', 'bar' ); Can anyone point me in a direction on how i can configure/change this?

• JDT: How to retrieve the correct IJavaElement to a corresponding RefactoringDescriptor?

  - by Chris

  I implement the IRefactoringExecutionListener interface in an Eclipse plug-in to get notified when the user refactors his code, so I can update a visual editor displaying corresponding UML Boxes accordingly. Now I have a RefactoringDescriptor and cannot manage to map it's information (project name as String, new name as String and resource path as IPath) to my model. My model is basically a Hashmap in which fully qualified names (String) of types are mapped instances of IJavaElement, or more precisely: IType. How can I "convert" between the two representations so I can update my model? Regards, Chris

• Domain-driven design with Zend

  - by mik

  This question is a continuation of my previous question here http://stackoverflow.com/questions/2122850/zend-models-architecture (big thanks to Bill Karwin). I've made some reading including this article http://weierophinney.net/matthew/archives/202-Model-Infrastructure.html and this question http://stackoverflow.com/questions/373054/how-to-properly-create-domain-using-zend-framework Now I understand, what domain driven design is. But examples are still very simple and poor. They are based on one table and one model. Now, my question is: do they use Domain Model Design in real-world PHP projects? I've been looking for some good documentation about this, but I haven't found anything good enough, that explains how to manage several tables and transfer them to Domain Objects. As long as I know, there is Hibernate library, that has this features in Java, but what should I use in PHP (Zend Framework)?

• Specification, modeling and programming are principially the same, right?

  - by Gabriel Šcerbák

  In formal specifications based on abstract algebraic types and equational theory you use formulas of equational theory to specify theory. System which will satisfy those constraints is called in formal logic a model. Modeling is process of creating a model, which abstracts of some aspects, which are unnecessary details for a specific case. So concrete system has to adhere to created model in observed aspects. Programming is a process of creating a program which will have specific behaviour - will perform specific algorithms - and programming languages through different paradigms enable us to think in a certain specific way, which abstracts of some details, usually machine specific ones. So could we be doing all those things at the same time, because they are principially the same? Is declarative programming the nearest attempt to do that? Could we use some sort f programming languages which will be good for programming as well as for modeling and specification?

• Symfony 1.3 and forms: the password changes when i click on 'Save', why??

  - by user248959

  Hi, i have installed sfDoctrineGuardUser and have created this model that inherits sfGuardUser model: Usuario: inheritance: extends: sfGuardUser type: simple columns: nombre_apellidos: string(60) sexo: boolean fecha_nac: date provincia: string(60) localidad: string(255) email_address: string(255) avatar: string(255) avatar_mensajes: string(255) I have also created a module called 'miembros' based on that model. Well, I log normally through sfGuardAuth/signin, then i go to "miembros/edit/id/$id_of_the_member_i_used_to_log_in" and push 'Save' button. Then i logout. If i try to log in again, it says: "The username and/or password is invalid". Later, i have realized that when click 'Save' the value of the field 'password' changes (well its encrypted version). So that is the reason why i can not then log in. But, why the value of the password change when i click on 'Save' ??? Regards Javi

• C# Design Layout/Patterns

  I am still fairly new to C# and I am trying to decide the best way to structure a new program. Here is what I want to do and I would like feed back on my idea. Presentation Layer Business Layer (Separate Class Library) Data Layer (Separate Class Library) Model Layer (Separate Class Library) What I am struggling with is if it is ok to have the classes in the Data Layer and Business Layer inherit from the types I define in Model Layer. This way I can extended the types as needed in my Business Layer with any new properties I see fit. I might not use every property from the Model type in my Business Layer class but is that really a big deal? If this isn't clear enough I can try and put together an example.

• PHP MVC Framework Structure

  - by bigstylee

  I am sorry about the amount of code here. I have tried to show enough for understanding while avoiding confusion (I hope). I have included a second copy of the code at Pastebin. (The code does execute without error/notice/warning.) I am currently creating a Content Management System while trying to implement the idea of Model View Controller. I have only recently come across the concept of MVC (within the last week) and trying to implement this into my current project. One of the features of the CMS is dynamic/customisable menu areas and each feature will be represented by a controller. Therefore there will be multiple versions of the Controller Class, each with specific extended functionality. I have looked at a number of tutorials and read some open source solutions to the MVC Framework. I am now trying to create a lightweight solution for my specific requirements. I am not interested in backwards compatibility, I am using PHP 5.3. An advantage of the Base class is not having to use global and can directly access any loaded class using $this->Obj['ClassName']->property/function();. Hoping to get some feedback using the basic structure outlined (with performance in mind). Specifically; a) Have I understood/implemented the concept of MVC correctly? b) Have I understood/implemented Object Orientated techniques with PHP 5 correctly? c) Should the class propertise of Base be static? d) Improvements? Thank you very much in advance! <?php /* A "Super Class" that creates/stores all object instances */ class Base { public static $Obj = array(); // Not sure this is the correct use of the "static" keyword? public static $var; static public function load_class($directory, $class) { echo count(self::$Obj)."\n"; // This does show the array is getting updated and not creating a new array :) if (!isset(self::$Obj[$class]) && !is_object(self::$Obj[$class])) //dont want to load it twice { /* Locate and include the class file based upon name ($class) */ return self::$Obj[$class] = new $class(); } return TRUE; } } /* Loads general configuration objects into the "Super Class" */ class Libraries extends Base { public function __construct(){ $this->load_class('library', 'Database'); $this->load_class('library', 'Session'); self::$var = 'Hello World!'; //testing visibility /* Other general funciton classes */ } } class Database extends Base { /* Connects to the the database and executes all queries */ public function query(){} } class Session extends Base { /* Implements Sessions in database (read/write) */ } /* General functionality of controllers */ abstract class Controller extends Base { protected function load_model($class, $method) { /* Locate and include the model file */ $this->load_class('model', $class); call_user_func(array(self::$Obj[$class], $method)); } protected function load_view($name) { /* Locate and include the view file */ #include('views/'.$name.'.php'); } } abstract class View extends Base { /* ... */ } abstract class Model extends Base { /* ... */ } class News extends Controller { public function index() { /* Displays the 5 most recent News articles and displays with Content Area */ $this->load_model('NewsModel', 'index'); $this->load_view('news', 'index'); echo $this->var; } public function menu() { /* Displays the News Title of the 5 most recent News articles and displays within the Menu Area */ $this->load_model('news/index'); $this->load_view('news/index'); } } class ChatBox extends Controller { /* ... */ } /* Lots of different features extending the controller/view/model class depending upon request and layout */ class NewsModel extends Model { public function index() { echo $this->var; self::$Obj['Database']->query(/*SELECT 5 most recent news articles*/); } public function menu() { /* ... */ } } $Libraries = new Libraries; $controller = 'News'; // Would be determined from Query String $method = 'index'; // Would be determined from Query String $Content = $Libraries->load_class('controller', $controller); //create the controller for the specific page if (in_array($method, get_class_methods($Content))) { call_user_func(array($Content, $method)); } else { die('Bad Request'. $method); } $Content::$var = 'Goodbye World'; echo $Libraries::$var .
