  • How to close a window (unload a NIB)?

    - by Paperflyer
    I have a custom NSWindowController subclass that loads a NIB file during initialization like this: self = [super initWithNibNamed:@"myNib"]; if (self != nil) { [self window]; } The nib contains some custom views and some other controls. The NSWindowController is the file's owner and at least one of the views even binds to it. Simply, what do I have to do to close and release that window? I spend the whole day trying to figure that out and I am still clueless. Please help me.

  • py.test import context problems (causes Django unit test failure)

    - by dhill
    I made a following test: # main.py import imported print imported.f.__module__ # imported.py def f(): pass # test_imported.py (py.test test case) import imported def test_imported(): result = imported.f.__module__ assert result == 'imported' Running python main.py, gives me imported, but running py.test gives me error and result value is moduletest.imported (moduletest is the name of the directory I keep the test in. It doesn't contain __init__.py, moduletest is the only directory containing *.py files in ~/tmp). How can I fix result value? The long story: I'm getting strange errors, while testing Django application. A call to reverse() from (django.urlresolvers). with function object foo as argument in tests crashes with NoReverseMatch: Reverse for 'site.app.views.foo'. The same call inside application works. I checked and it is converted to 'app.views.foo' (without site prefix). I first suspected my customised test setup for Django, but then I made above test.

  • PRISM View Injection/Navigation in Same Module

    - by Jeaffrey Gilbert
    This is ModuleInit.cs in Products module public class ModuleInit : IModule { private readonly IUnityContainer _container; private readonly IRegionManager _regionManager; public ModuleInit(IUnityContainer container, IRegionManager regionManager) { _container = container; _regionManager = regionManager; } #region IModule Members public void Initialize() { App app = (App)Application.Current; _regionManager.RegisterViewWithRegion(RegionNames.ModuleRegionProducts, () => _container.Resolve<Views.ProductsCycle>()); } #endregion } Below is button event handler in ProductsCycle.cs to go to another view still within same module: private void btnForward_Click(object sender, RoutedEventArgs e) { IRegion productsRegion = _regionManager.Regions["ModuleRegionProducts"]; var productsListView = _container.Resolve<Views.ProductsList>(); productsRegion.Add(productsListView, "ProductsList"); productsRegion.Activate(productsListView); } State: ProductsCycle page is successfully loaded on first load. Problem: View doesn't changed from ProductCycle page to ProductsList page when btnForward is clicked. I'm using Silverlight 4 and PRISM2. Please your advice, thank you.

  • How to conditionally execute a jquery validation?

    - by Pandiya Chendur
    I am validating form using jquery validation plugin...... rules: { Name: "required", MobileNo: { required: true, minlength: 10, remote: '<%=Url.Action("getClientMobNo", "Clients") %>' }, Address: "required" }, messages: { Name: "please provide a client name", MobileNo: { required: "Please provide a mobile phone no", rangelength: jQuery.format("Enter at least {0} characters"), remote: jQuery.format("This MobileNo is already in use") }, Address: "please provide client address" }, This works pretty well on add form validation but i use the same form for edit here they can use the same mobile no,but my plugin validates that mobileno saying there is already a mobileno... But how to execute remote attribute based on a condition, MobileNo: { required: true, minlength: 10, if($("#HfId").val() == ""){ remote: '<%=Url.Action("getClientMobNo", "Clients") %>' } }, Is this a valid jquery conditional validation statement.... How to skip remote attribute based on a condition....

  • Silverlight with MVVM Inheritance: ModelView and View matching the Model

    - by moonground.de
    Hello Stackoverflowers! :) Today I have a special question on Silverlight (4 RC) MVVM and inheritance concepts and looking for a best practice solution... I think that i understand the basic idea and concepts behind MVVM. My Model doesn't know anything about the ViewModel as the ViewModel itself doesn't know about the View. The ViewModel knows the Model and the Views know the ViewModels. Imagine the following basic (example) scenario (I'm trying to keep anything short and simple): My Model contains a ProductBase class with a few basic properties, a SimpleProduct : ProductBase adding a few more Properties and ExtendedProduct : ProductBase adding another properties. According to this Model I have several ViewModels, most essential SimpleProductViewModel : ViewModelBase and ExtendedProductViewModel : ViewModelBase. Last but not least, according Views SimpleProductView and ExtendedProductView. In future, I might add many product types (and matching Views + VMs). 1. How do i know which ViewModel to create when receiving a Model collection? After calling my data provider method, it will finally end up having a List<ProductBase>. It containts, for example, one SimpleProduct and two ExtendedProducts. How can I transform the results to an ObservableCollection<ViewModelBase> having the proper ViewModel types (one SimpleProductViewModel and two ExtendedProductViewModels) in it? I might check for Model type and construct the ViewModel accordingly, i.e. foreach(ProductBase currentProductBase in resultList) if (currentProductBase is SimpleProduct) viewModels.Add( new SimpleProductViewModel((SimpleProduct)currentProductBase)); else if (currentProductBase is ExtendedProduct) viewModels.Add( new ExtendedProductViewModels((ExtendedProduct)currentProductBase)); ... } ...but I consider this very bad practice as this code doesn't follow the object oriented design. The other way round, providing abstract Factory methods would reduce the code to: foreach(ProductBase currentProductBase in resultList) viewModels.Add(currentProductBase.CreateViewModel()) and would be perfectly extensible but since the Model doesn't know the ViewModels, that's not possible. I might bring interfaces into game here, but I haven't seen such approach proven yet. 2. How do i know which View to display when selecting a ViewModel? This is pretty the same problem, but on a higher level. Ended up finally having the desired ObservableCollection<ViewModelBase> collection would require the main view to choose a matching View for the ViewModel. In WPF, there is a DataTemplate concept which can supply a View upon a defined DataType. Unfortunately, this doesn't work in Silverlight and the only replacement I've found was the ResourceSelector of the SLExtensions toolkit which is buggy and not satisfying. Beside that, all problems from Question 1 apply as well. Do you have some hints or even a solution for the problems I describe, which you hopefully can understand from my explanation? Thank you in advance! Thomas

  • Global variable life in Javascript - destroyed on a reload?

    - by Paul Nathan
    (I am learning Javascript) Problem: A page I am working on has 2 views, a data entry view with a textbox and a data rendering view. There is a a href src="currentpage#" link that switches between the 2 views. In order to transmit data from view to view, the javascript parses it from the current HTML and pushes it into the correct form for the other view. This is ugly and I want to refactor it out, ideally into some sort of global where it can be neatly rendered down into the view on command (I'm refactoring the code base to a point where I can AJAX it from a server). However, I am not certain about scoping rules and variable life in JS.

  • PHP/Javascript - get php variable within javascript

    - by McNabbToSkins
    I have run into an interesting problem. I am currently developing php page and need to access a php variable within the javascript onload. $(document).ready(function() { var temp = <?php $page_id ?> } is this valid? I know that this might seem weird and not be allowed but I am developing a page that has two popup windows. The windows are created using the same view template and there is no way to distinguish between each other. If I stored a hidden value on the page with information unique to the page like so <input type="hidden" value="<?php $page_id ?> id="page_id" /> if there are two views open at the same time there is no way for me to get a unique page id like so var temp = $("#page_id").val(); Because there are two views witht he same input id that is not unique. Long story short is it valid to reference a php variable in the javascript.

  • How do I use theme preprocessor functions for my own templates?

    - by Jergason
    I have several .tpl.php files for nodes, CCK fields, and Views theming. These template files have a lot of logic in them to move things around, strip links, create new links, etc. I understand that this is bad development and not "The Drupal Way". If I understand correctly, "The Drupal Way" is to use preprocessor functions in your template.php file to manipulate variables and add new variables. A few questions about that: Is there a naming convention for creating a preprocessor function for a specific theme? For example, if I have a CCK field template called content-field-field_transmission_make_model.tpl, how would I name the preprocessor function? Can I use template preprocessor functions for node templates, CCK field templates, and Views templates? Do they have different methods of modifying template variables or adding new ones?

  • Using GLOrtho to view Side, Front, Top perspectives of a 3D scene

    - by talldan
    Dear all, I'm building a game level editing app as part of a university project. In my application I have multiple viewports, a Perspective viewport and three orthographic views all setup to view the same scene. I've successfuly setup the orthographic views and can translate and scale them to mimic scrolling and zooming. Unfortunately, I'm having one problem - my scene still contains 3 dimensions, so objects viewed in orthographic mode of certain depths are clipped when they fall outside of my clipping volume. Most 3D authoring tools or level editors allow you to view all objects in orthographic mode regardless of depth. I guess what I need to do is scale my scene in the appropriate dimension so that all values lie between 1 and -1, is there a straightforward way of going about this? Or is there a different better approach. Thanks very much for your help, Dan

  • a question about rails general practice with REST, json, and ajax

    - by Nik
    Hi all, I have this question concerning REST I think: I have read a few rest tutorials and the feeling I get from them is that each action in a restful controller tends to be lean and almost single purpose: "Index gives off a collection of a model show gives off one model edit/new a prep place for changing/create a model update/create changes and makes new model deletes removes one model" After reading all these tutorials, rest seems to be to be a means to create an interface for a model, much like active resource type of thing. the mantra seems to be "controller provides data and data only and is also pretty convention over configuration, so expect projects_path to return a bunch of projects" I can understand that, and I like the cleanliness. But here's when I run into some trouble in reality in applying these guidelines: say three models, Project with attrib title, User with attrib name, and Location with attrib address. Say in views/users/index.html.erb, I want to use Ajax to fetch and display a project in a div#project_display when the user clicks on a project element, I know that I can use views/projects/show.js.rjs like this: page.replace_html 'project_display' "#{@project.name}" where in the projects_controller.rb def show @project = Project.find(params[:id]) repsond_to do |format| format.js and other formats... end end I have no problem in doing that for a couple of years now. BUT doesn't that mean that my JS response for the project#show action is LOCkED to present data to div#project_display element and show only whatever I that rjs template says it should show? That's very limiting and doesn't sound very "interface" like. I have never used JSON before or much XML, so I thought, maybe the JS response should send back raw stuff, like JSON and somehow the page on which the ajax request was called has the instruction on what do to with these raw data. That sounds a lot more flexible, doesn't it? Because look back at that exmpale, what if in the views/locations/index.html.erb, I want to do the exact same thing except I want to put the response in div#project_goes_here and the response should be #{project.name} I know this is a trivial change but that's the point: the RJS only allows one template at a time. So I think the JSON route is the way to go, but how does the already loaded page, the one that the ajax call came from, know when or how to "look forward" to incoming data? I read that PrototypeJS has this template thing, I wouldn't mind using it with JSON, but if you can demonstrate this or other means for displaying received-from-ajax data, I am all attention. Thank You

  • Two different definitions of database schema

    - by AspOnMyNet
    a) I found two definitions of schema: FIRST - A set of information that describes a table is known as a schema, and schemas are used to describe specific tables within a database, as well as entire databases (and the relationship between tables in them, if any). SECOND - A database schema is a way to logically group objects such as tables, views, stored procedures etc. Think of a schema as a container of objects. I assume the two descriptions describe entirely different concepts, which just happen to use the same name? b) A database schema is a way to logically group objects such as tables, views, stored procedures etc. Think of a schema as a container of objects. If I understand the above definition correctly, then database schema is similar to a namespace, only difference being that we can assign access permissions to database schema, while same can’t be done with namespaces? thanx

  • Adding HTML to the DOM through the client.

    - by Mantorok
    Hi all Just wanted your views on the most efficient way to render content on demand, the reason this has come to light is that I'm maintaining a AA compliant website and we recently added video to it, and one of the techniques to avoid invalidation was to add the HTML for the video to the DOM after the page has loaded - which is fine and working ok. However, I found 2 possible techniques and I would appreciate some views, the one I'm currently using is an AJAX call that returns the HTML, the other technique is a hidden field that contains the HTML - I'm presently using the former. The main reason I'm asking the question is because there may be times when this particular control is also requested via an AJAX call, so I would end up with back-to-back AJAX calls, which seems a bit inefficient to me. I hope this makes sense, are there any better techniques to achieve this? Am I worrying too much over the consecutive AJAX calls? Thanks

  • can i change the black background of an iphone app?

    - by Cristi Balu?a
    My app is structured like this, a single MainWindow with window backgroundColor to white(which doesn't appear anywhere anyway), and in this nib i have a UINavigationController which doesn't seems to have a backgroundColor. Any view controller is added from code and made from code and they have a gray background. What happens is that when i rotate the iphone and the views are rotating as well, i see a black background under my views. Can this be changed? It looks ugly especially if i have a photo that is rotating in the same time with my gray background.

  • Seam page navigation with includes

    - by Marc
    Hello, I'm using seam page navigation rules. and did not experience any problem with adding rules which redirect from one page to another. But since I designed my page views using those redirection simply don't happen anymore for those pages. Tried to define the rule to the view that gets included, then to the view that includes the others (which to me was making more sense) but none work. Is there anything special about page navigation in seam using included view-id ? I'm using jsf, xhtml as my page views. Thanks

  • Set Window Properties based on Datatype of UserControl

    - by Kage
    I've got a simple window, that is container for various views. I've got a DataTemplate that shows the correct view based on whatever the window's MainViewModel property is set to. <DataTemplate DataType="{x:Type VM:StartupViewModel}"> <AdornerDecorator> <V:StartupView /> </AdornerDecorator> </DataTemplate> What I'd like to do is for certain views, change some properties on the base window, ie WindowStyle, ResizeMode etc. something like triggers, but on datatypes instead of property values? How could I accomplish this?

  • Django Multi-Table Inheritance VS Specifying Explicit OneToOne Relationship in Models

    - by chefsmart
    Hope all this makes sense :) I'll clarify via comments if necessary. Also, I am experimenting using bold text in this question, and will edit it out if I (or you) find it distracting. With that out of the way... Using django.contrib.auth gives us User and Group, among other useful things that I can't do without (like basic messaging). In my app I have several different types of users. A user can be of only one type. That would easily be handled by groups, with a little extra care. However, these different users are related to each other in hierarchies / relationships. Let's take a look at these users: - Principals - "top level" users Administrators - each administrator reports to a Principal Coordinators - each coordinator reports to an Administrator Apart from these there are other user types that are not directly related, but may get related later on. For example, "Company" is another type of user, and can have various "Products", and products may be supervised by a "Coordinator". "Buyer" is another kind of user that may buy products. Now all these users have various other attributes, some of which are common to all types of users and some of which are distinct only to one user type. For example, all types of users have to have an address. On the other hand, only the Principal user belongs to a "BranchOffice". Another point, which was stated above, is that a User can only ever be of one type. The app also needs to keep track of who created and/or modified Principals, Administrators, Coordinators, Companies, Products etc. (So that's two more links to the User model.) In this scenario, is it a good idea to use Django's multi-table inheritance as follows: - from django.contrib.auth.models import User class Principal(User): # # # branchoffice = models.ForeignKey(BranchOffice) landline = models.CharField(blank=True, max_length=20) mobile = models.CharField(blank=True, max_length=20) created_by = models.ForeignKey(User, editable=False, blank=True, related_name="principalcreator") modified_by = models.ForeignKey(User, editable=False, blank=True, related_name="principalmodifier") # # # Or should I go about doing it like this: - class Principal(models.Model): # # # user = models.OneToOneField(User, blank=True) branchoffice = models.ForeignKey(BranchOffice) landline = models.CharField(blank=True, max_length=20) mobile = models.CharField(blank=True, max_length=20) created_by = models.ForeignKey(User, editable=False, blank=True, related_name="principalcreator") modified_by = models.ForeignKey(User, editable=False, blank=True, related_name="principalmodifier") # # # Please keep in mind that there are other user types that are related via foreign keys, for example: - class Administrator(models.Model): # # # principal = models.ForeignKey(Principal, help_text="The supervising principal for this Administrator") user = models.OneToOneField(User, blank=True) province = models.ForeignKey( Province) landline = models.CharField(blank=True, max_length=20) mobile = models.CharField(blank=True, max_length=20) created_by = models.ForeignKey(User, editable=False, blank=True, related_name="administratorcreator") modified_by = models.ForeignKey(User, editable=False, blank=True, related_name="administratormodifier") I am aware that Django does use a one-to-one relationship for multi-table inheritance behind the scenes. I am just not qualified enough to decide which is a more sound approach.

  • How to return all aspnet_compiler errors (not just those in first directory)

    - by Dan Atkinson
    Hi there! Is there a way to get the aspnet_compiler to go through all views and return all errors, rather than just the errors in the current view directory? For example, lets say I have a project that has a bunch of folders... Views Folder1 Folder2 Folder3 Folder4 Two of them (Folder2 and Folder3) have errors. aspnet_compiler will run, and only return the errors it comes across in Folder2. It won't return those in Folder3 at the same time. Once I fix the errors in Folder2 and run it again, it'll then pick up the ones in the Folder3. I fix those. And then have to run the tool again, and again until it's all fixed. This is getting annoying!! For reference, here's the command I use: C:\Windows\Microsoft.NET\Framework\v2.0.50727\aspnet_compiler -v / -p "C:\path\to\project" Thanks in advance!

  • Replacing IFrame with div

    - by Roland
    I have a IFrame where I load in a custom search, and display the results within the iframe. The search results I obtain by calling an external url, that returns a value. I need to implement the same thing for a mobi site that works on mobile devices, and thus I need to replace the IFrame with something else. Will this be possible using a div tag, since most mobile devices do not support frames. And no javascript may be used. Any advice will be appreciated.

  • iPhone grouped table view cell reuse

    - by William Jockusch
    My iPhone programs frequently contain grouped table views. A typical use might be for settings. The number of rows in these table views can run anywhere from roughly 2 to 20. The cells typically don't have a lot of uniformity. Should I be trying to reuse the cells? If so, how much commonality do cells need to have to get a shared identifier? For example, consider two cells with the same size, but one contains a slider and the other contains a label. Or is this just not worth the bother? Thanks

  • ACL suggestions needed for a small light framework developed

    - by Sai
    Hello all, I've developed a small framework that was needed for the firm that I work. The problem is I've not made a full level framework, as developers are finding tough time to understand what is what, So I made a simple structure with app/controllers, app/models, app/views so that they can clearly separate the code and can get used to higher frameworks later. All other things like components/modules/helpers are just coded for now in a file called app_functions.php. The above framework is derived from cakePHP, not all, but just the framework uses a modified code of dispatcher of cake. The models all work with normal sqls, and views with pure html using a template engine. Now I'm trying to develop a small application over it, it cameout well, but ACL is something which many versions of it have not proved that satisfactory. Can anybody suggest a good ACL. I've checked phpGACL(too heavy), Zend_ACL likely won't be compatible, Cakephp's ACL which wont fit in the structure,as we are not using cake's SQLs, as there too many queries hitting the database for one page display.

  • In Prism (CAL), how can I RegisterPresenterWithRegion instead of RegisterViewWithRegion

    - by Edward Tanguay
    I have a module in a Prism application and in its initialize method I want to register a presenter instead of a view with a region, i.e. I want to do this: PSEUDO-CODE: regionManager.RegisterPresenterWithRegion( "MainRegion", typeof(Presenters.EditCustomerPresenter)); instead of loading a view like this: regionManager.RegisterViewWithRegion( "MainRegion", typeof(Views.EditCustomerView)); The presenter would of course bring along its own view and ultimately register this view in the region, but it would allow me to bind the presenter to the view in the presenter's constructor instead of binding the two together in XAML (which is more of a decoupled MVVM pattern which I want to avoid here). How can I add a Presenter to a Region instead of a view? namespace Client.Modules.CustomerModule { [Module(ModuleName = "CustomerModule")] public class CustomerModule : IModule { private readonly IRegionManager regionManager; public CustomerModule(IRegionManager regionManager) { this.regionManager = regionManager; } public void Initialize() { regionManager.RegisterViewWithRegion("MainRegion", typeof(Views.EditCustomerView)); } } }
