  • help with Zend dispatcher

    - by simple
    this is the Zend Controller Dispatcher Standart public function isDispatchable(Zend_Controller_Request_Abstract $request) { $className = $this->getControllerClass($request); echo 'is dispatchanble started'; var_dump($className); if (!$className) { return false; } var_dump(class_exists($className, false)); if (class_exists($className, false)) { return true; } $fileSpec = $this->classToFilename($className); $dispatchDir = $this->getDispatchDirectory(); $test = $dispatchDir . DIRECTORY_SEPARATOR . $fileSpec; return Zend_Loader::isReadable($test); } I need to set up custom modular structure and loading just using plugins (I need to setup the path where zend looks for controller), so I am stuck tracing down I came to the isDispatchable method that returns false and consequently the dispatching returns error . This method returns false because class_exists return false , it is surely has to do with auto loading ,but confused. help will be appreciated,though I got the feeling that I am looking at wrong place.

  • In QT 4.6 w/ Webkit: How to handle popup window requests (WebView::createWindow)?

    - by CM
    Hi all, I'm new to QT and have been trying to create a test browser. What I'm trying to do now is to handle js-based popup requests. After reading the QT documentation, I learned that I need to re-implement the QWebView::createWindow method to do just that. Now I've re-implemented this method, but it seems to be not called when I try to click a link that triggers a popup window. Can any one help me? Do I need to subclass both the WebView and WebPage classes? If so, how do I do that? I'm quite new to QT and I've done tons of searches and found nothing. Thank you all in advance for any hint and advice!

  • Function naming: sendCharacter or receiveCharacter?

    - by bobobobo
    I'm trying to name a function that runs when a character is received by the object. For the caller, it should be named sendCharacter, so that it can call: object->sendCharacter( character ) ; That looks nice for the caller.. but for the receiver, it implements a method /// Called when this object is do something /// with a character /// from the caller void sendCharacter( char c ) ; So for the recipient class, it looks like this method will actually send a character out, not receive one. So then, I could call the function receiveCharacter /// Called when this object is do something /// with a character /// from the caller void receiveCharacter( char c ) ; But now the caller does this: object->receiveCharacter( character ) ; Which just looks odd. How can I better name this function?

  • will_paginate route only works on page > 1

    - by Avishai
    I have the following routes defined: map.resources :categories, :has_many => :downloads map.resources :downloads, :member => {:go => :get}, :collection => {:tag => :get} map.connect '/downlods/page/:page', :controller => 'downloads', :action => 'index' map.connect '/categories/:category_id/downloads/page/:page', :controller => 'downloads', :action => 'index' For some reason, the first page that the will_paginate helper is called on causes links with ?page=2 to be rendered, while subsequent pages have links with /downloads/page/2. Do you know what might be causing this?

  • Real-world examples of populating a GWT CellTable using a clean MVP pattern?

    - by piehole
    We are using the GWT-Presenter framework and attempting to use CellTable to put together an updateable grid. It seems as though several of the GWT constructs for CellTable don't lend themselves to easily breaking up the logic into clean view and presenter code. Examples: 1) Within the View's constructor, the CellTable is defined and each column is created by anonymous inner classes that extend the Column class to provide the onValue() method. 2) The FieldUpdater interface must be implemented to provide logic to execute when a user alters data in a cell. This seems like it would best fit in the Presenter's onBind() method, but FieldUpdaters often need access to the Cell or Column which belong in the view. CellTable does not have accessor methods to get hold of the Columns or Cells, so it seems the only way for the Presenter to get them is for me to create a multitude of member variables on the View and accessors on my Display interface. Can anyone provide good examples for dealing with CellTable in GWT-Presenter or a comparable MVP

  • C# Constructor Problem When Using Generics

    - by Jimbo
    Please see an example of my code below: public class ScrollableCheckboxList { public List<ScrollableCheckboxItem> listitems; public void ScrollableCheckboxList<TModel>(IEnumerable<TModel> items, string valueField, string textField, string titleField) where TModel : class { listitems = new List<ScrollableCheckboxItem>(); foreach (TModel item in items) { Type t = typeof(TModel); PropertyInfo[] props = new [] { t.GetProperty(textField), t.GetProperty(valueField), t.GetProperty(titleField) }; listitems.Add(new ScrollableCheckboxItem { text = props[0].GetValue(item, null).ToString(), value = props[1].GetValue(item, null).ToString(), title = props[2].GetValue(item, null).ToString() }); } } } The code produces the following error: 'ScrollableCheckboxList': member names cannot be the same as their enclosing type This clearly means that there is a method in the class that has the same name as the class, but usually insinuates that the method is trying to return something (which is not allowed) In my case, all I have done is declare a constructor - why would this be a problem?

  • Is there an autorelease pool in class methods?

    - by mystify
    I have an class method which generates an UIView, like this: + (UIImage*)imageWithFileName:(NSString*)imgFile { UIImage *img = nil; NSBundle *appBundle = [NSBundle mainBundle]; NSString *resourcePath = [appBundle pathForResource:imgFile ofType:nil]; if (resourcePath != nil) { NSURL *imageURL = [NSURL fileURLWithPath:resourcePath]; NSData *data = [[NSData alloc] initWithContentsOfURL:imageURL]; img = [UIImage imageWithData:data]; // should be autoreleased!! [data release]; } return img; } However, when I use this, the image data is NEVER freed. There is definitely a memory bug with this, although I didn't break any memory management rule I am aware of. My guess is that because this is a class method which gets called from instance methods, There is no active autorelease pool in place or it's one that only gets drained when I quit the app. Could that be right?

  • Line breaks in XML are ignored by the SAX Parser

    - by Siddharth Iyer
    I am parsing an XML with some CData that contains line breaks. The parser ignores these line breaks. I am trying to figure out a way to catch these newlines in the characters() method and replace them with a break tag for display purposes. I have tried almost everything under the sun and have been scouring stackoverflow for the past 3 hours. I tried every combination of replacing "\n", "\r\n" and so on with a break tag in the characters() method of the parser. I am absolutely helpless right about now.... and would sincerely appreciate any help I can get. Thanks!!!

  • grailsApplication not getting injected in a service , Grails 2.1.0

    - by vijay tyagi
    I have service in which i am accessing few configuration properties from grailsApplication I am injecting it like this class MyWebService{ def grailsApplication WebService webService = new WebService() def getProxy(url, flag){ return webService.getClient(url) } def getResponse(){ def proxy = getProxy(grailsApplication.config.grails.wsdlURL, true) def response = proxy.getItem(ItemType) return response } } When i call getProxy() method, i see this in tomcat logs No signature of method: org.example.MyWebService.getProxy() is applicable for argument types: (groovy.util.ConfigObject, java.lang.Boolean) values: [[:], true] Possible solutions: getProxy(), getProxy(java.lang.String, boolean), setProxy(java.lang.Object) which means grailsApplication is not getting injected into the service, is there any alternate way to access configuration object ? according to burtbeckwith's post configurationholder has been deprecated, can't think of anything else. Interestingly the very same service works fine in my local IDE(GGTS 3.1.0), that means locally grailsApplication is getting injected, but when i create a war to deploy to a standalone tomcat, it stops getting injected.

  • Methods specific only to an instance? What are they called in Ruby?

    - by daremarkovic
    I know there are "instance methods", "class methods" but what are these types of methods called, for eg: s1 = "This is my STRING!" def s1.m1 downcase end p s1 # => "This is my STRING!" p s1.m1 # => "this is my string!" What type of method is the "m1" method called on the s1 "instance" of the "string" class? It's really weird because I didn't know this was possible at all if I try: s2 = "This is ANOTHER string" s2.m1 # => Won't work! Which kind of makes sense, but not sure why defining methods like m1 on instances on a class are useful at all.

  • Major inconsistencies in Zend Framework

    - by John Nall
    Okay first of all let me just say Zend Framework is the greatest tool I have ever used in 30+ years of programming (well, for web development, Qt wins the desktop market). However, through my use I have noticed some glaring and annoying inconsistencies. For instance, Zend_Form_Element's have a setAttrib() method. Now why the hell is this the only method in that API which is abbrev.? Why then am I using setRequired() instead of setReq()? I have more examples, I am extremely nerd raged about this. It is completely ruining what could have been God's gift to web development. FOR FUTURE REFERENCE NEVER ABBREV. THINGS WHEN MAKING AN API. also always filter data before storing it i m o Who do we talk to about this, where something will actually get done about it?

  • Iphone Orientation Change

    - by SG
    I am trying to implement orientation change functionality in my application.I have overrided -(void) didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation. In this method i change the frame size of the tableview(including the position of the cell items) which is present in the view. The tableview Details: Added to the view as [self.view addSubView:tableView] in the viewDidLoad method of the view controller; Cell item (row) has a textfield and a segmented control. There are 10 cells in the table view and in landscape mode only 2 cells are visible and in potrait mode 5 cells are visible. I have implemented scroller. Issue: Certain times on changing the orientation to potrait mode certain segmented controls in the cell are not rendered (Not shown at all). This happens when i am viewing the last couple of cells in the landscape mode and i change the orientation to potrait mode.

  • Can someone explain Kohana 3's routing system?

    - by alex
    In bootstrap.php, where you set routes, I'm having a hard time getting them to work. I read some documentation a while ago that I can't seem to find again that explains them. Here is one of my examples Route::set('products', 'products/(type)', array('type' => '.+')) ->defaults(array( 'controller' => 'articles', 'action' => 'view_product', 'page' => 'shock-absorbers', )); I thought that would mean a request like products/something would load up the articles controller, and the action_view_product method. But I can't get it to work. Can someone please explain to me exactly how they work, and what all the method parameters are?

  • Forcing LINQ to SQL to make one single call for all child rows

    - by zaph0d
    Let say I have a method (example taken from another post): public IQueryable<CityBlock> GetCityBlocks(){ var results = from o in db.city_blocks let buildings = GetBuildingsOnBlock(o.block_id) //returns Iqueryable select new CityBlock { BuildingsOnBlock = buildings, BlockOwner = o.block_owner }; return results; } In the calling method I add Skip() and Take() methods plus some filtering and then do a ToList(). The trouble is that I am getting dozens of database calls - one for all the city blocks and then a separate one for each building. Is there a way that I can refactor this code to just make two calls: one for the city blocks and one for all the buildings

  • How to clone a model's attributes easily?

    - by Zabba
    I have these models: class Address < ActiveRecord::Base belongs_to :event attr_accessible :street, :city validates :street, :city, :presence => true end class Event < ActiveRecord::Base has_one :address accepts_nested_attributes_for :address end If I do the below assignment in the Events create action and save the event I get an error: #Use the current user's address for the event @event.address_attributes = current_user.address.attributes #Error occurs at the above mentioned line ActiveRecord::RecordNotFound (Couldn't find Address with ID=1 for Event with ID=) I think what's happening is that all the address's attributes (including the primary key) is getting assigned in the @event.address_attributes = line. But all I really want is the "real data" (street, city), not the primary keys or created_at etc to get copied over. I suppose I could write a small method to do this sort of selective copy but I can't help but feel there must be some built-in method for this? What's the best/right way to do this?

  • WPF textbox derived control override drag&drop OnPreviewDrop (C sharp)

    - by Petr Klus
    Hi, I have been working on my custom control derived from the TextBox and I have encountered a problem I can not solve right now. Brief description of the problem: my textbox contains plain text which contains tags which I want to keep consistent - so far I have overriden text selection so they can be selected only as a whole tag etc. Right now I have moved to processing of drag&drop. If any text is dropped on the textfield and it is dropped on the tag, I want the insertion to be moved before or after the tag. The actual problem is with setting of the e.Handled=true. If I set it to true, it almost works - the text is inserted via my routine, but it is not removed from the source. If I set it to false, after executing my method the original textbox's insertion method is run. Is there any way to alter event routing? Or am I approaching this wrong from the start? Code of my method: protected override void OnPreviewDragEnter(DragEventArgs e) { base.OnPreviewDragEnter(e); e.Handled = true; // let us draw our very own caret... } protected override void OnPreviewDrop(DragEventArgs e) { base.OnPreviewDrop(e); fieldsReady = false; int selStart = this.SelectionStart; int selLength = this.SelectionLength; string droppedData = (string)e.Data.GetData(DataFormats.StringFormat); // where to insert Point whereDropped = e.GetPosition(this); int droppedIndex = GetCharacterIndexFromPoint(whereDropped, true); if (droppedIndex == this.Text.Length - 1) { double c = GetRectFromCharacterIndex(droppedIndex).X; if (whereDropped.X > c) droppedIndex++; } // only if the source was us, do this: if (this.SelectionLength > 0) // this means that we are dragging from our textbox! { // was there any selection? if so, remove it! this.Text = this.Text.Substring(0, selStart) + this.Text.Substring(selStart + selLength); e.Handled = true; // 2DO!! alter the indices depending on the removed selection // insertion this.Text = this.Text.Substring(0, droppedIndex) + droppedData + this.Text.Substring(droppedIndex); } }

  • Design pattern for data entry forms with LINQ2SQL

    - by petebob796
    I am about to start a new winforms data entry application, it already has the database designed which I am comfortable with. I was going to use LINQ2SQL to access the tables to keep things type safe but am now wondering about design patterns, something I am just getting into. Since LINQ is giving me objects to use should I still create classes in between to hold the validation code and helper methods or should these just go in with the UI? It just seems I will end up with classes sat in between with little code which will cause the UI classes to have code just getting and setting values in the intermediate class and returning from validation to flag errors... Any good reading on this? Should I consider the entity framework (or similar) instead?

  • DDD: Where to create entity objects?

    - by ciscoheat
    I have three entities that must interact: User, SupportTicketand PhoneConversation. When someone calls in requesting help, the User should have a SupportTicket assigned to him, with a PhoneConversation assigned to the Ticked describing the call. My question is: In what entity should I put the method CreatePhoneSupportTicket() that creates a new SupportTicket and a PhoneConversation, relates them to each other and finally relates the SupportTicket to the User? I'm guessing it can't be on the user because that would violate the SRP (the user does a few more things). But the method itself does more than one thing, it should create both a SupportTicket and a PhoneConversation. Is this a situation when a Service is a better solution then putting methods on entities? Thanks for your help!
