  • How to configure a has_many association with non-ActiveRecord model

    - by Callmeed
    My Rails app has a normal ActiveRecord "Account" model stored in the database. The model will store the URL to a remote XML file which defines some other objects. For example, the Account has_many :galleries but the Gallery model is simply defined by nodes in the XML document. So how do I get /accounts/1/galleries to show the galleries from that account's XML? How do I setup this relationship? I know how to do basic non-AR models, but I'm not sure how to define the association or if I need to create a Gallery model at all.

  • Ninject and Custom Controller Factory

    - by Baddie
    I'm using MEF with ASP.NET MVC as demonstrated at http://blog.maartenballiauw.be/post/2009/06/17/Revised-ASPNET-MVC-and-the-Managed-Extensibility-Framework-(MEF).aspx. When I try to use Ninject, it seems that nothing gets injected. I did some debugging, and when I reverted to the original controller factory the injection worked. What needs to be changed, or what does Ninject need in terms of controller factories for it to work?

  • Screening (multi)collinearity in a reggresion model

    - by aL3xa
    I hope that this one is not going to be "ask-and-answer" question... here goes: (multi)collinearity refers to extremely high correlations between predictors in the regression model. How to cure them... well, sometimes you don't need to "cure" collinearity, since it doesn't affect regression model itself, but interpretation of an effect of individual predictors. One way to spot collinearity is to put each predictor as a dependent variable, and other predictors as independent variables, determine R2, and if it's larger than .9 (or .95), we can consider predictor redundant. This is one "method"... what about other approaches? Some of them are time consuming, like excluding predictors from model and watching for b-coefficient changes - they should be noticeably different. Of course, we must always bare in mind specific context/goal of analysis... Sometimes, only remedy is to repeat a research, but right now, I'm interested in various ways of screening redundant predictors when (multi)collinearity occurs in a regression model.

  • iOS Switching an embedded view in storyboard

    - by Coyote6
    I have been trying to figure this out all day and I know it should be able to be done, but being new to iOS development using Objective-C and not Appcelerator I'm having newbie issues. What I am trying to accomplish is to have an embedded view in one of my other views, but to be able to switch which view is embedded through programming. I am using storyboards. When I tried to use the view container it displays the attached view, but I cannot attach multiple views to the container in the storyboard. I drew up an image, but to my annoyance I cannot post an image on here because I don't have enough "rep" points, so I posted it on my site: http://static.c6gx.com/images/iphone-embedded-views-diagram.jpg Later on I would like what appears to be a push segue, within that view container, but first I just want to be able to switch between embedded view 1, 2, 3, etc. Am I supposed to be using a view container to accomplish this, or some other type of controller? Then how would I call the transition to change the view? Thank you for any help you can provide.

  • Ninject: Controller Constructor with int argument

    - by Fleents
    How can you instantiate a Controller that has an int argument? Using Ninject.. My HomeController has a constructor like this: private int _masterId; Public HomeController(int masterId){ _masterId = masterId; } I created a controller factory like this: public class NinjectControllerFactory : DefaultControllerFactory { IKernel kernel = new StandardKernel(new ExampleConfigModule()); protected override IController GetControllerInstance(Type controllerType) { return controllerType == null ? null : (IController)kernel.Get(controllerType, 1); } }

  • TDD a controller with ASP.NET MVC 2, NUnit and Rhine Mocks

    - by Nissan Fan
    What would a simple unit test look like to confirm that a certain controller exists if I am using Rhino Mocks, NUnit and ASP.NET MVC 2? I'm trying to wrap my head around the concept of TDD, but I can't see to figure out how a simple test like "Controller XYZ Exists" would look. In addition, what would the unit test look like to test an Action Result off a view?

  • Custom OData operation / customize EF model to hide join table in many-to-many relationship

    - by AC
    I've got a data model that has two tables with a join table for a many to many relationship & creating an OData service to expose the data for CRUD ops in a Silverlight app. What I'd like to do is abstract the join table from the service. I'm not sure if the best way to do this would be in the model (using EF in .NET3.5SP1) or if I should do it with a custom service operation. If I do it in the EF model (not sure how I'd do this), then the OOTB WCF Data Service stuff would make it easy to say [..]/Courses(1)/Modules ... otherwise I'd have to create a custom operation to do this. Is it possible to do this in the EF model and if so, how does that work?

  • Problems using the Razor model when creating my knockout ViewModel

    - by Emil Kantis
    I'm having problems with using the Model in a javascript call when setting up my knockout VM.. @model List<AdminGui.Models.Domain> <script src="http://ajax.aspnetcdn.com/ajax/knockout/knockout-2.2.1.js" type="text/javascript"></script> <script type="text/javascript"> function ViewModel() { var self = this; self.domains = ko.observableArray( ko.utils.arrayMap(@Model, function(item) { return new Domain(item.guid, item.description, item.namespaces); })); } I get a syntax error on @Model in the ko.utils.arrayMap call. I suspect it might be my Razor-fu that is lacking... :)

  • Using USB PS2 hand controller in C#.NET

    - by rross
    I'm attempting to create a program that takes input from a usb ps2 hand controller, translate and passes the info to a rs232 device. I already have everything working for the rs232 device. The problem is interfacing with a usb controller. There doesn't seem to be any good documentation out there and on top of that .NET3.0/3.5 doesn't have any libs to help you out. How would one even get started?

  • Asp.Net MVC Handle Drop Down Boxes that are not part of the Model

    - by Pino
    I have a small form which the user must fill in and consists of the following fields. Name (Text) Value (Text) Group (Group - Is a list of option pulled from a database table) Now the Model for this View looks like so, public string Name { get; set; } public string Value { get; set; } public int GroupID { get; set; } Now the view is Strongly Typed to the above model. What method would one use to populate the drop down list? Since the data is not contained within the Model (It could be contained in the Model) should we be using Temp/View data? A HTML Helper? What would be the ideal way to achieve this.

  • Django updating a single model

    - by Hellnar
    Hello How can I use the update() method on a single model which I retrieved via Queryset.get() ? It seems like model. Model doesn't have an update() method yet I cannot invoke .save() as I have a pre-save signals which messes things up. EDIT: An idea would be passing some parameter to the save method and catching it at the pre_save signal, so that I can understand the purpose, how can this be done ? Thanks

  • ModelName(django.contrib.auth.models.User) vs ModelName(models.Model)

    - by amr.negm
    I am developing a django project. I created some apps, some of those are related to User model, for instance, I have a feeds app that handles user feeds, and another app that deals with extra user data like age, contacts, and friends. for each of these, I created a table that should be connected to the User model, which I using for storing and authenticating users. I found two ways to deal with this issue. One, is through extending User model to be like this: ModelName(User): friends = models.ManyToMany('self') ..... Two, is through adding a foreign key to the new table like this: ModelName(models.Model): user = models.ForeignKey(User, unique=True) friends = friends = models.ManyToMany('self') ...... I can't decide which to use in which case. in other words, what are the core differences between both?

  • Updating database row from model

    - by Jamie Dixon
    Hey everyone, I'm haing a few problems updating a row in my database using Linq2Sql. Inside of my model I have two methods for updating and saving from my controller, which in turn receives an updated model from my view. My model methods like like: public void Update(Activity activity) { _db.Activities.InsertOnSubmit(activity); } public void Save() { _db.SubmitChanges(); } and the code in my Controller likes like: [HttpPost] public ActionResult Edit(Activity activity) { if (ModelState.IsValid) { UpdateModel<Activity>(activity); _activitiesModel.Update(activity); _activitiesModel.Save(); } return View(activity); } The problem I'm having is that this code inserts a new entry into the database, even though the model item i'm inserting-on-submit contains a primary key field. I've also tried re-attaching the model object back to the data source but this throws an error because the item already exists. Any pointers in the right direction will be greatly appreciated. UPDATE: I'm using dependancy injection to instantiate my datacontext object as follows: IMyDataContext _db; public ActivitiesModel(IMyDataContext db) { _db = db; }

  • How can I disable a model field in a django form

    - by jammon
    I have a model like this: class MyModel(models.Model): REGULAR = 1 PREMIUM = 2 STATUS_CHOICES = ((REGULAR, "regular"), (PREMIUM, "premium")) name = models.CharField(max_length=30) status = models.IntegerField(choices = STATUS_CHOICES, default = REGULAR) class MyForm(forms.ModelForm): class Meta: model = models.MyModel In a view I initialize one field and try to make it non-editable: myform = MyForm(initial = {'status': requested_status}) myform.fields['status'].editable = False But the user can still change that field. What's the real way to accomplish what I'm after?

  • MVC Custom Model Binder Binding Multiple Values

    - by BMD86
    Hello everyone, I have a scenario in which I have multiple sources to bind to my model. For one, I have a view tied to a strongly-typed model, but this scenario also entails posting data to this view from a 3rd party site. Essentially, what I believe I am after in the custom model binding is to investigate the form values in the Request object within HTTPContext to see if I have a field such as "postedFirstName". If so, I want to bind that value instead of the textbox "FirstName" in my view. I've done a good bit of searching but have not find anything that exactly addresses such a scenario. This link was close, I thought, but not quite: http://stackoverflow.com/questions/970335/asp-net-mvc-mixing-custom-and-default-model-binding Any input is greatly appreciated!

  • Cakephp with underscore table ignores model

    - by xiaohouzi79
    Hi, I have one table metrics and another table metric_levels. In the Metric model I have $hasMany = 'MetricLevels' but anything inside the MetricLevels model is totally ignored. But, if I rename the model to 'Metric' and have $useTable = 'metric_levels' it works fine. I've tried all combinations, but none seem to work. I've tried plurals, singulars, underscores, nothing seems to work. The model is simply ignored and it just takes the value from the database. Any help is appreciated.

  • model.matrix() with na.action=NULL?

    - by Vincent
    I have a formula and a data frame, and I want to extract the model.matrix(). However, I need the resulting matrix to include the NAs that were found in the original dataset. If I were to use model.frame() to do this, I would simply pass it na.action=NULL. However, the output I need is of the model.matrix() format. Specifically, I need only the right-hand side variables, I need the output to be a matrix (not a data frame), and I need factors to be converted to a series of dummy variables. I'm sure I could hack something together using loops or something, but I was wondering if anyone could suggest a cleaner and more efficient workaround. Thanks a lot for your time! And here's an example: dat <- data.frame(matrix(rnorm(20),5,4), gl(5,2)) dat[3,5] <- NA names(dat) <- c(letters[1:4], 'fact') ff <- a ~ b + fact # This omits the row with a missing observation on the factor model.matrix(ff, dat) # This keeps the NA, but it gives me a data frame and does not dichotomize the factor model.frame(ff, dat, na.action=NULL) Here is what I would like to obtain: (Intercept) b fact2 fact3 fact4 fact5 1 1 0.7266086 0 0 0 0 2 1 -0.6088697 0 0 0 0 3 NA 0.4643360 NA NA NA NA 4 1 -1.1666248 1 0 0 0 5 1 -0.7577394 0 1 0 0 6 1 0.7266086 0 1 0 0 7 1 -0.6088697 0 0 1 0 8 1 0.4643360 0 0 1 0 9 1 -1.1666248 0 0 0 1 10 1 -0.7577394 0 0 0 1

  • Passing a model into RedirectToAction()

    - by larryq
    I'm curious how this works. In MVC you can call View() and pass a model as a parameter, but RedirectToAction (one of its incarnations at least) takes a 'routeValues' object, which appears to be the closest match. If your model is passed in this parameter will that model type be available in the subsequent action method? Or are there caveats involved that might prevent accurate translation in some circumstances?
