• Setting date from selectInputDate to object

  - by DD

  I have a date controller which does various things. Once a calendar date is set, I want to pass the value from the date controller to another bean. The problem I have is that the setPropertyActionListener gets called before the user clicks on a date. Is there a way to get the date from the selectInputDate after selection and pass to a bean? This is what I tried: <ice:selectInputDate popupDateFormat="dd-MMM-yyyy" renderAsPopup="true" value="#{dateRangeDateContoller.end}" > <f:setPropertyActionListener target="#{searchParameters.endDate}" value="#{dateRangeDateContoller.end}" /> </ice:selectInputDate>

• Dismiss a custom dialog?

  - by YaW

  Hi, I'm trying to make a custom dialog to show a view in this dialog. This is the Builder code: //Getting the layout LayoutInflater inflater = (LayoutInflater) getSystemService(LAYOUT_INFLATER_SERVICE); View layout = inflater.inflate(R.layout.custom_dialog_simple, (ViewGroup) findViewById(R.id.rlDialogSimple)); //Change Text and on click TextView tvDialogSimple = (TextView) layout.findViewById(R.id.tvDialogSimple); tvDialogSimple.setText(R.string.avisoComprobar); Button btDialogSimple = (Button) layout.findViewById(R.id.btDialogSimple); btDialogSimple.setOnClickListener(new OnClickListener() { public void onClick(View v) { //Do some stuff //Here i want to close the dialog } }); AlertDialog.Builder builder = new AlertDialog.Builder(AcPanelEditor.this); builder.setView(layout); AlertDialog alert = builder.create(); alert.show(); So, i want to dismiss the dialog in the onClick of btDialogSimple. How i can do it? I don't know how to call the dismiss method from inside a onclicklistener. My buttons have a custom layout, so i don't want to make a builder.setPositiveButton. Any ideas?

• Getting the last User ID in Zend Framework

  - by Ryan Murphy

  Using MySQL query browser, I manually made a table called users and input some date in the fields. I set the primary key to id and set it to auto increment. There are 3 rows, the highest id is 3. I then made the following class in the method directory to call upon the data in the table etc. class Application_Model_DbTable_User extends Zend_Db_Table_Abstract { protected $_name = 'user'; public function getLatestUserId() { $id = $this->getAdapter()->lastInsertId(); return $id; } } In the controller I do the following which gets the value generated by the method and lets the view access it: $usersDbModel = new Application_Model_DbTable_User(); $lastUserId = $usersDbModel->getLatestUserId(); $this->view->lastUserId = $lastUserId; In the view I then echo it to display it to the user: echo $this->lastUserId; However, even though my last id in the users table is 3. It displays 0. I have also tried: public function getLatestUserId() { $sql = 'SELECT max(id) FROM user'; $query = $this->query($sql); $result = $query->fetchAll(); return $result; } But this just throws out a server error. What have I done wrong? Am I missing something? Is there another way of doing this?

• How do I create multiple submit buttons for the same form in Rails?

  - by Angela

  I need to have multiple submit buttons. I have a form which creates an instance of Contact_Call. One button creates it as normal. The other button creates it but needs to have a different :attribute value from the default, and it also needs to set the attribute on a different, but related model used in the controller. How do I do that? I can't change the route, so is there a way to send a different variable that gets picked up by [:params]? And if I do then, what do I do in the controller, set up a case statement?

• cakephp why can't I have an admin route and a superuser route?

  - by Jack B Nimble

  In core.php I can define Configure::write('Routing.admin', 'admin'); and /admin/controller/index will work. but if I define both Configure::write('Routing.admin', 'admin'); Configure::write('Routing.superuser', 'superuser'); and try to look at /superuser/blah/index/ instead of it saying the controller doesn't exist it says Error: SuperuserController could not be found. instead of saying Error: BlahController could not be found. When I first read the documentation I was under the impression I could run both routes, and not just one or the other. Is there something more I need to do?

• Loading UINavigationController from another nib automatically by UITabBarController

  - by porneL

  I think I've found the cause: Document Info window in IB has a warning: "'Selected Navigation Controller (Second)' has nib name property set to 'SecondView.nib', but this view controller is not intended to have its view set in this manner." Bummer. I've built nib in Interface Builder that has UITabBarController at top level and switches between UINavigationControllers. It works fine when everything is in a single nib file, but I'd like to use separate nib files for UINavigationControllers. Starting with Apple's TabBar template, if I just change class of SecondView to UINavigationController, it all breaks: and all I get is this: Is it possible to have separate file for UINavigationController without programmatically setting everything? I would like TabBarController to handle loading and unloading of nibs.

• What makes an effective UI for displaying versioning of structured hierarchical data

  - by Fadrian Sudaman

  Traditional version control system are displaying versioning information by grouping Projects-Folders-Files with Tree view on the left and details view on the right, then you will click on each item to look at revision history for that configuration history. Assuming that I have all the historical versioning information available for a project from Object-oriented model perspective (e.g. classes - methods - parameters and etc), what do you think will be the most effective way to present such information in UI so that you can easily navigate and access the snapshot view of the project and also the historical versioning information? Put yourself in the position that you are using a tool like this everyday in your job like you are currently using SVN, SS, Perforce or any VCS system, what will contribute to the usability, productivity and effectiveness of the tool. I personally find the classical way for display folders and files like above are very restrictive and less effective for displaying deep nested logical models. Assuming that this is a greenfield project and not restricted by specific technology, how do you think I should best approach this? I am looking for idea and input here to add values to my research project. Feel free to make any suggestions that you think is valuable. Thanks again for anyone that shares their thoughts.

• PyQt QAbstractListModel seems to ignore tristate flags

  - by mcieslak

  I've been trying for a couple days to figure out why my QAbstractLisModel won't allow a user to toggle a checkable item in three states. The model returns the Qt.IsTristate and Qt.ItemIsUserCheckable in the flags() method, but when the program runs only Qt.Checked and Qt.Unchecked are toggled on edit. class cboxModel(QtCore.QAbstractListModel): def __init__(self, parent=None): super(cboxModel, self).__init__(parent) self.cboxes = [ ['a',0], ['b',1], ['c',2], ['d',0] ] def rowCount(self,index=QtCore.QModelIndex()): return len(self.cboxes) def data(self,index,role): if not index.isValid: return QtCore.QVariant() myname,mystate = self.cboxes[index.row()] if role == QtCore.Qt.DisplayRole: return QtCore.QVariant(myname) if role == QtCore.Qt.CheckStateRole: if mystate == 0: return QtCore.QVariant(QtCore.Qt.Unchecked) elif mystate == 1: return QtCore.QVariant(QtCore.Qt.PartiallyChecked) elif mystate == 2: return QtCore.QVariant(QtCore.Qt.Checked) return QtCore.QVariant() def setData(self,index,value,role=QtCore.Qt.EditRole): if index.isValid(): self.cboxes[index.row()][1] = value.toInt()[0] self.emit(QtCore.SIGNAL("dataChanged(QModelIndex,QModelIndex)"), index, index) print self.cboxes return True return False def flags(self,index): if not index.isValid(): return QtCore.Qt.ItemIsEditable return QtCore.Qt.ItemIsEnabled | QtCore.Qt.ItemIsEditable | QtCore.Qt.ItemIsUserCheckable | QtCore.Qt.ItemIsTristate You can test it with this, class MainForm(QtGui.QMainWindow): def __init__(self, parent=None): super(MainForm, self).__init__(parent) model = cboxModel(self) self.view = QtGui.QListView() self.view.setModel(model) self.setCentralWidget(self.view) app = QtGui.QApplication(sys.argv) form = MainForm() form.show() app.exec_() and see that only 2 states are available. I'm assuming there's something simple I'm missing. Any ideas? Thanks!

• Searching in Ruby on Rails - How do I search on each word entered and not the exact string?

  - by bgadoci

  I have built a blog application w/ ruby on rails and I am trying to implement a search feature. The blog application allows for users to tag posts. The tags are created in their own table and belong_to :post. When a tag is created, so is a record in the tag table where the name of the tag is tag_name and associated by post_id. Tags are strings. I am trying to allow a user to search for any word tag_name in any order. Here is what I mean. Lets say a particular post has a tag that is 'ruby code controller'. In my current search feature, that tag will be found if the user searches for 'ruby', 'ruby code', or 'ruby code controller'. It will not be found if the user types in 'ruby controller'. Essentially what I am saying is that I would like each word entered in the search to be searched for, not necessarily the 'string' that is entered into the search. I have been experimenting with providing multiple textfields to allow the user to type in multiple words, and also have been playing around with the code below, but can't seem to accomplish the above. I am new to ruby and rails so sorry if this is an obvious question and prior to installing a gem or plugin I thought I would check to see if there was a simple fix. Here is my code: View: /views/tags/index.html.erb <% form_tag tags_path, :method => 'get' do %> <p> <%= text_field_tag :search, params[:search], :class => "textfield-search" %> <%= submit_tag "Search", :name => nil, :class => "search-button" %> </p> <% end %> TagsController def index @tags = Tag.search(params[:search]).paginate :page => params[:page], :per_page => 5 @tagsearch = Tag.search(params[:search]) @tag_counts = Tag.count(:group => :tag_name, :order => 'count_all DESC', :limit => 100) respond_to do |format| format.html # index.html.erb format.xml { render :xml => @tags } end end Tag Model class Tag < ActiveRecord::Base belongs_to :post validates_length_of :tag_name, :maximum=>42 validates_presence_of :tag_name def self.search(search) if search find(:all, :order => "created_at DESC", :conditions => ['tag_name LIKE ?', "%#{search}%"]) else find(:all, :order => "created_at DESC") end end end

• Should Factories Persist Entities?

  - by mxmissile

  Should factories persist entities they build? Or is that the job of the caller? Pseudo Example Incoming: public class OrderFactory { public Order Build() { var order = new Order(); .... return order; } } public class OrderController : Controller { public OrderController(IRepository repository) { this.repository = repository; } public ActionResult MyAction() { var order = factory.Build(); repository.Insert(order); ... } } or public class OrderFactory { public OrderFactory(IRepository repository) { this.repository = repository; } public Order Build() { var order = new Order(); ... repository.Insert(order); return order; } } public class OrderController : Controller { public ActionResult MyAction() { var order = factory.Build(); ... } } Is there a recommended practice here?

• WYSIWYG with Qt - font size woes

  - by Rob

  I am creating a custom Qt widget that mimics an A4 printed page and am having problems getting fonts to render at the correct size. My widget uses QPainter::setViewport and QPainter::setWindow to mimic the A4 page, using units of 10ths of a millimetre which enables me to draw easily. However, attempting to create a font at a specific point size doesn't seem to work and using QFont:setPixelSize isn't accurate. Here is some code: View::View(QWidget *parent) : QWidget(parent), printer(new QPrinter) { printer->setPaperSize(QPrinter::A4); printer->setFullPage(true); } void View::paintEvent(QPaintEvent*) { QPainter painter(this); painter.setWindow(0, 0, 2100, 2970); painter.setViewport(0, 0, printer->width(), printer->height()); // Draw a rect at x = 1cm, y = 1cm, 6cm wide and 1 inch high painter.drawRect(100, 100, 600, 254); // Create a 72pt (1 inch) high font QFont font("Arial"); font.setPixelSize(254); painter.setFont(font); // Draw in the same box // The font is too large painter.drawText(QRect(100, 100, 600, 254), tr("Wg\u0102")); // Ack - the actual font size reported by the metrics is 283 pixels! const QFontMetrics fontMetrics = painter.fontMetrics(); qDebug() << "Font height = " << fontMetrics.height(); } So I'm asking for a 254 high font (1 inch, 72 pts) and it's too big and sure enough when I query for the font height via QFontMetrics it is 283 high. Does anyone else know how to use font sizes in points when using custom mapping modes like this? It must be possible. Note that I cannot see how to convert between logical/device points either (i.e. the Win32 DPtoLP/LPtoDP equivalents.)

• Is it possible to specify Jquery File Upload to post back only once (for multiple files)?

• DDD and MVC Models hold ID of separate entity or the entity itself?

  - by Dr. Zim

  If you have an Order that references a customer, does the model include the ID of the customer or a copy of the customer object like a value object (thinking DDD)? I would like to do ths: public class Order { public int ID {get;set;} public Customer customer {get;set;} ... } right now I do this: public class Order { public int ID {get;set;} public int customerID {get;set;} ... } It would be more convenient to include the complete customer object rather than an ID to the View Model passed to the form. Otherwise, I need to figure out how to get the vendor information to the view that the order references by ID. This also implies that the repository understand how to deal with the customer object that it finds within the order object when they call save (if we select the first option). If we select the second option, we will need to know where in the view model to put it. It is certain they will select an existing customer. However, it is also certain they may want to change the information in-place on the display form. One could argue to have the controller extract the customer object, submit customer changes separately to the repository, then submit changes to the order, keeping the customerID in the order.

• How to implement a caching model without violating MVC pattern?

  - by RPM1984

  Hi Guys, I have an ASP.NET MVC 3 (Razor) Web Application, with a particular page which is highly database intensive, and user experience is of the upmost priority. Thus, i am introducing caching on this particular page. I'm trying to figure out a way to implement this caching pattern whilst keeping my controller thin, like it currently is without caching: public PartialViewResult GetLocationStuff(SearchPreferences searchPreferences) { var results = _locationService.FindStuffByCriteria(searchPreferences); return PartialView("SearchResults", results); } As you can see, the controller is very thin, as it should be. It doesn't care about how/where it is getting it's info from - that is the job of the service. A couple of notes on the flow of control: Controllers get DI'ed a particular Service, depending on it's area. In this example, this controller get's a LocationService Services call through to an IQueryable<T> Repository and materialize results into T or ICollection<T>. How i want to implement caching: I can't use Output Caching - for a few reasons. First of all, this action method is invoked from the client-side (jQuery/AJAX), via [HttpPost], which according to HTTP standards should not be cached as a request. Secondly, i don't want to cache purely based on the HTTP request arguments - the cache logic is a lot more complicated than that - there is actually two-level caching going on. As i hint to above, i need to use regular data-caching, e.g Cache["somekey"] = someObj;. I don't want to implement a generic caching mechanism where all calls via the service go through the cache first - i only want caching on this particular action method. First thought's would tell me to create another service (which inherits LocationService), and provide the caching workflow there (check cache first, if not there call db, add to cache, return result). That has two problems: The services are basic Class Libraries - no references to anything extra. I would need to add a reference to System.Web here. I would have to access the HTTP Context outside of the web application, which is considered bad practice, not only for testability, but in general - right? I also thought about using the Models folder in the Web Application (which i currently use only for ViewModels), but having a cache service in a models folder just doesn't sound right. So - any ideas? Is there a MVC-specific thing (like Action Filter's, for example) i can use here? General advice/tips would be greatly appreciated.

• How to fix: unrecognized selector sent to instance

  I am having a problem that may be simple to fix, but not simple for me to debug. I simple have a button inside a view in IB; the file's owner is set to the view controller class I am using and when making the connections, everything seems fine, ie. the connector is finding the method I am trying to call etc. however, I am receiving this error: Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[UIApplication getStarted:]: unrecognized selector sent to instance 0x3d19130' My code is as follows: RootViewController.h @interface RootViewController : UIViewController { IBOutlet UIButton* getStartedButton; } @property (nonatomic, retain) UIButton* getStartedButton; - (IBAction) getStarted: (id)sender; @end RootViewController.m #import "RootViewController.h" #import "SimpleDrillDownAppDelegate.h" @implementation RootViewController @synthesize getStartedButton; - (void)viewDidLoad { [super viewDidLoad]; } - (IBAction) getStarted: (id)sender { NSLog(@"Button Tapped!"); //[self.view removeFromSuperview]; } - (void)dealloc { [getStartedButton release]; [super dealloc]; } @end Seems simple enough...any thoughs?

• Where to place a query that should be included in all or most views

  - by Andrew

  In my application I have a sidebar which I want to include a list of pages. Cheating on the MVC setup, I can pretty easily display this as follows (in HAML): # layouts/_sidebar.html.haml %h4 Pages %ul.pages - for page in Page.all %li= link_to page.title, page Now, this works just fine, but clearly it's against the convention. The problem is, this shared layout partial is present in most (but not all) views, and therefore to serve the pages from the controller layer would mean needing to inject an instance variable into almost every controller action in the application. That isn't very clean or DRY. So, how would you handle this kind of situation? Is there a clean, DRY place to put this kind of a simple query that respects Rails MVC convention better?

• Can't add to NSMutableArray from SecondaryView

  - by Antonio

  Hi guys, I've searched and read and still haven't found a concrete answer. Brief: I have an application where I declare an NSMutableArray in my AppDelegate to synthesize when the application loads. (code below). I have a SecondaryViewController call this function, and I have it output a string to let me know what the array size is. Every time I run it, it executes but it does not add any objects to the array. How do I fix this? AppDelegate.h file #import <UIKit/UIKit.h> @class arrayTestViewController; @interface arrayTestAppDelegate : NSObject <UIApplicationDelegate> { UIWindow *window; arrayTestViewController *viewController; NSMutableArray *myArray3; } @property (nonatomic, retain) NSMutableArray *myArray3; @property (nonatomic, retain) IBOutlet UIWindow *window; @property (nonatomic, retain) IBOutlet arrayTestViewController *viewController; -(void)addToArray3; @end AppDelegate.m file #import "arrayTestAppDelegate.h" #import "arrayTestViewController.h" @implementation arrayTestAppDelegate @synthesize window; @synthesize viewController; @synthesize myArray3; #pragma mark - #pragma mark Application lifecycle - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { myArray3 = [[NSMutableArray alloc] init]; // Override point for customization after application launch. // Add the view controller's view to the window and display.

• ASP.NET MVC Viewmodel trouble...

  - by ile

  I've already started similar topic, but still didn't find final solution... So here I am with new one :) ... I'm developing NerdDinner from scratch and now I came to point where I define DinnerViewModel. Following these instructions (starting from Listing 5) I came to this: namespace Nerd.Controllers { // View Model Classes public class DinnerViewModel { public DinnerViewModel(List<Dinner> dinners) { this.Dinners = dinners; } public List<Dinner> Dinners { get; private set; } } public class DinnerController : Controller { private DinnerRepository dinnerRepository = new DinnerRepository(); .... public ActionResult NewDinners() { // Create list of products var dinners = new List<Dinner>(); dinners.Add(new Dinner(/*Something to add*/)); // Return view return View(new DinnerViewModel(dinners)); } } } Also, the Dinner table in this new version of NerdDinner is a bit shortened (it contains of DinnerID, Title, EventDate and Description fields). No matter what I try to add here dinners.Add(new Dinner(/*Something to add*/)); I always get following error Error 1 'Nerd.Model.Dinner' does not contain a constructor that takes '1' arguments C:\Documents and Settings\ilija\My Documents\Visual Studio 2008\Projects\Nerd\Nerd\Controllers\DinnerController.cs 150 25 Nerd Because I'm total beginner in C# and generally OOP, I have no idea what to do here... I suppose I need to declare a constructor, but how and where exactly? Thanks, Ile

• Using the same code in different (partial) views

  Maybe this question is quite simple because I'm new to MVC2. I have a simple demo MVC project. (1) A weak-typed view: Index.aspx <% Html.RenderPartial("ArticalList", ViewData["AllArticals"] as List<Artical>); %> (2) A strong-typed partical view: ArticalList.ascx <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<List<Artical>>" %> <% foreach (Artical a in Model) { %> <%= Html.ActionLink(a.Title, "About", new { id = a.ID })%><br /> <%} %> (3) Here is the HomeController.cs public ActionResult Index() { ViewData["AllArticals"] = Artical.GetArticals(); return View(); } public ActionResult ArticalList() { return PartialView(Artical.GetArticals()); } Sorry I'm using a Web-Form "angle", because if I'm using a Web-Form, when I visit Index.aspx, rendering ArticalList.ascx will call public ActionResult ArticalList(). But here I need to write Artical.GetArticals() twice in two actions. How can I put them in one?

• When should we use Views, Temporary Tables and Direct Queries ? What are the Performance issues in a

  - by Shantanu Gupta

  I want to know the performance of using Views, Temp Tables and Direct Queries Usage in a Stored Procedure. I have a table that gets created every time when a trigger gets fired. I know this trigger will be fired very rare and only once at the time of setup. Now I have to use that created table from triggers at many places for fetching data and I confirms it that no one make any changes in that table. i.e ReadOnly Table. I have to use this tables data along with multiple tables to join and fetch result for further queries say select * from triggertable By Using temp table select ... into #tx from triggertable join t2 join t3 and so on select a,b, c from #tx --do something select d,e,f from #tx ---do somethign --and so on --around 6-7 queries in a row in a stored procedure. By Using Views create view viewname ( select ... from triggertable join t2 join t3 and so on ) select a,b, c from viewname --do something select d,e,f from viewname ---do somethign --and so on --around 6-7 queries in a row in a stored procedure. This View can be used in other places as well. So I will be creating at database rather than at sp By Using Direct Query select a,b, c from select ... into #tx from triggertable join t2 join t3 join ... --do something select a,b, c from select ... into #tx from triggertable join t2 join t3 join ... --do something . . --and so on --around 6-7 queries in a row in a stored procedure. Now I can create a view/temporary table/ directly query usage in all upcoming queries. What would be the best to use in this case.

• MVC3 DropDownListFor selected value does not reset if I set the Id

  - by BarryFanta

  I've read a lot of posts on here regarding the dropdown selected value issues (not showing etc etc...) but mine is the opposite problem. I want the drop down to always reset after the view is returned after a button submits the page through the controller action. So how I've structured it all works but is it possible to reset the dropdown list each time? I can't find a way to do it and I've tried a lot of ways, believe me. My View: @Model.PspSourceModel.PayAccount.PaymentProviderId <br /> @Html.DropDownListFor( x => x.PspSourceModel.PayAccount.PaymentProviderId, new SelectList(Model.PspSourceModel.PaymentProviders, "Value", "Text", "-- please select --"), "-- please select --" My Controller: // I've tried forcing the selected value id here - doesn't effect the dropdownlist still? pspVM.PspSourceModel.PayAccount.PaymentProviderId = 1; return (View(pspVM)); My Webpage shows: 1 (the id I set in the Action) dropdownlist with the id=6 or whatever value was chosen prior to submitting the form. From the questions and answers on SO and the wider web I thought the dropdownlist seems tied to the id you choose but how do I override that to reset the dropdown to 'please select' each time? Thanks in advance.

  I have this unit test: [TestMethod] public void Delete_Post_Passes_With_State_4() { //Arrange ViewResult result = stateController.Delete( 4 ) as ViewResult; var model = (State)result.ViewData.Model; //Act RedirectToRouteResult redirectResult = stateController.Delete( model ) as RedirectToRouteResult; var newresult = stateController.Delete( 4 ) as ViewResult; var newmodel = (State)newresult.ViewData.Model; //Assert Assert.AreEqual( redirectResult.RouteValues["action"], "Index" ); Assert.IsNull( newmodel ); } Here are the two controller actions that handle deleting: // // GET: /State/Delete/5 public ActionResult Delete(int id) { var x = _stateService.GetById( id ); return View(x); } // // POST: /State/Delete/5 [HttpPost] public ActionResult Delete(State model) { try { if( model == null ) { return View( model ); } _stateService.Delete( model ); return RedirectToAction("Index"); } catch { return View( model ); } } What I can't figure out is why this test fails. I have verified that the record actually gets deleted from the list. If I set a break point in the Delete method on the line: var x = _stateService.GetById( id ); The GetById does indeed return a null just as it should, but when it gets back to the newresult variable in the test, the ViewData.Model is the deleted model. What am I doing wrong?
