• insertNewObjectForEntityForName:inManagedObjectContext: returning NSNumber bug?

  - by beinstein

  I'm relatively well versed in CoreData and have been using it for several years with little or no difficulty. For the life of me, I can't figure out why insertNewObjectForEntityForName:inManagedObjectContext: is all of a sudden returning some sort of strange instance of NSNumber. GDB says the returned object is of the correct custom subclass of NSManagedObject, but when I go to print a description of the NSManagedObject itself, I get the following error: *** -[NSCFNumber objectID]: unrecognized selector sent to instance 0x3f26f50 What's even stranger, is that I'm able to set some relationships and attributes using setValue:forKey: and all is good. But when I try to set one specific relationship, I get this error: *** -[NSCFNumber entity]: unrecognized selector sent to instance 0x3f26f50 I've tried everything from clean all targets, to restarting both mac and iPhone, even editing the model so that the relationship in question is to-one instead of to-many. No matter what I do, the same problem appears. Has anyone ever seen anything like this before?

• rails ajax redirect

  - by badnaam

  Here is my use case I have a search model with two actions search_set and search_show. 1 - A user loads the home page which contains a search_form, rendered via a partial (search_form). 2 - User does a search, and the request goes to search_set, the search is saved and a redirect happens to search_show page which again renders the search_form with the saved search preferences. This search form is different than the one if step1, because it's a remote form being submitted to the same action (search set) 3 - Now the user does another search, and the search form is submitted via ajax to the search_set action. The search is saved and executed and now I need to present the result via rjs templates (corresponding to search_show). I am told that if the request is xhr then I can't redirect to the search_show action? Is that right? If yes, how do I handle this? Here is my controller class http://pastie.org/993460 Thanks

• What is an example of MVC in PHP?

  - by waiwai933

  I'm trying to understand the MVC pattern. Here's what I think MV is: Model: <?php if($a == 2){ $variable = 'two'; } else{ $variable = 'not two'; } $this->output->addContent($variable); $this->output->displayContent(); ?> View: <?php class output{ private $content; public function addContent($var){ $this->content = 'The variable is '.$var; } public function displayContent(){ include 'header.php'; echo $content; include 'footer.php'; } } ?> Is this right? If so, what is the controller?

• Active Record/ORM vs Normal Forms?

  - by Arsenal

  Hello, I've been playing around with Active Record a bit, and I have noticed that A.C./ORM always uses the following database model when creating a one-to-one relationship Person id | country_id | name | ... Country id | tld | name | ... No I wondered, isn't this a violiation of the third Normal Form? This clearly states "Every non-prime attribute is non-transitively dependent on every key of the table". Well this country_id isn't dependent of personid is it? So is this wrong or am I just not getting the point?

• rails 3.0.3 - ActiveRecord::Relation, undefined method error

  - by brg

  I am having this unexplained ActiveRecord::Relation, undefined method error .

• Are there Python ORMs out there that support multiple independent databases concurrently in use?

  - by sdt

  I'm writing an application in Python where I wish to use sqlite as the backing store for documents edited by the app, with documents generally living in memory, but being saved to disk-based databases when the application saves. Ideally I'd like to use something like an ORM to make access to the data from my Python application code simple. Unfortunately it seems like the majority of Python ORMs, including SQLAlchemy, SQLObject, Django, and Storm, associate the database connection (or engine or whatever) with the classes representing table data, rather than instances of those classes. This restricts these ORMs to working with a single database connection across all instances. Since I'd like to support having multiple documents open simultaneously, this isn't going to work for me. Are there any ORMs out there that support this usage model in Python? Bazaar seems to support this, but it's quite out of date, and at first glance appears to have some other shortcomings. Thanks for any suggestions!

• Use Automapper to flatten sub-class of property

  - by Neil

  Given the classes: public class Person { public string Name { get; set; } } public class Student : Person { public int StudentId { get; set; } } public class Source { public Person Person { get; set; } } public class Dest { public string PersonName { get; set; } public int? PersonStudentId { get; set; } } I want to use Automapper to map Source - Dest. This test obviously fails: Mapper.CreateMap<Source, Dest>(); var source = new Source() { Person = new Student(){ Name = "J", StudentId = 5 }}; var dest = Mapper.Map<Source, Dest>(source); Assert.AreEqual(5, dest.PersonStudentId); What would be the best approach to mapping this given that "Person" is actually a heavily used data-type throughout our domain model.

• What is your favorite convention for organizing a ASP.NET project?

  - by Michael Rosario

  Hello world. My team is starting a brand new ASP.NET solution which will probably become large. Inspired by ASP.NET MVC, we currently express all data access objects in a model project. We, however, do not have good conventions for organizing ASP.NET ascx's and aspx's. We have already reviewed DotNetNuke and want to avoid the complexity of driving the whole application through a single default.aspx . What is the best way to organize a non-MVC ASP.NET solution? Your tips, links, and advice are greatly appreciated!

• C#: How to remove items from the collection of a IDictionary<E, ICollection<T>> with LINQ?

  - by Rosarch

  Here is what I am trying to do: private readonly IDictionary<float, ICollection<IGameObjectController>> layers; foreach (ICollection<IGameObjectController> layerSet in layers.Values) { foreach (IGameObjectController controller in layerSet) { if (controller.Model.DefinedInVariant) { layerSet.Remove(controller); } } } Of course, this doesn't work, because it will cause a concurrent modification exception. (Is there an equivalent of Java's safe removal operation on some iterators?) How can I do this correctly, or with LINQ?

• Ways to call Blocks within Magento: createBlock vs Layout xml file

  - by N. B.

  Context: I'm trying to include Adminhtml blocks in the frontend of the site to replace some of the user account blocks. The first thing I'm trying to do is simply display the block on the correct page. I can replace the entire page by setting the Body of the response inside the controller, but I'm having a hard time including the block in the layout xml file and then calling it within the template. Why would I be able to create an adminhtml/sales_order_grid from Mage_Sales_OrderController using createBlock: $this->getResponse()->setBody($this->getLayout()->createBlock('adminhtml/sales_order_grid')->toHtml()); But not from a frontend layout, using a declaration <block type="adminhtml/sales_order_grid" name="orders_widget"/> within app/design/frontend/default/default/layout/sales.xml The latter produces an error without a stack trace: Fatal error: Call to a member function toHtml() on a non-object in app/code/core/Mage/Core/Model/Layout.php on line 526 Thanks for any guidance!

• Core Data Null Relationship

  - by Dylan Copeland

  I have a to-one relationship in my data model with Core Data. I'm trying to set the value of the relationship but Core Data keeps thinking that it's nil. The "creatorUser" relationship is not optional, so when I go to save my managed object context, Core Data gives errors because it thinks the "creatorUser" is nil. Any help would be greatly advised. NSManagedObject *teamManagedObject = [NSEntityDescription insertNewObjectForEntityForName:@"DCTeam" inManagedObjectContext:_managedObjectContext]; // Creator Properties NSManagedObject *creator = [self userForID:[ticketInfo objectForKey:@"userid"]]; if (!creator) { creator = [NSEntityDescription insertNewObjectForEntityForName:@"DCUser" inManagedObjectContext:_managedObjectContext]; [creator setValue:[personInfo objectForKey:@"userid"] forKey:@"userid"]; [creator setValue:[personInfo objectForKey:@"creatorName"] forKey:@"name"]; } [teamManagedObject setValue:creator forKey:@"creatorUser"];

• What is the technological basis for Azure DocumentDB?

  - by user1703840

  Microsoft announced the availability of Azure DocumentDB as follows... A fully-managed, highly-scalable, NoSQL document database service. - Rich query over a schema-free JSON data model - Transactional execution of JavaScript logic - Scalable storage and throughput - Tunable consistency - Rapid development with familiar technologies - Blazingly fast and write optimized database service I really like the "transactional execution of JavaScript logic". Sounds like an approach similar to that of PostgreSQL NoSQL. Anyone know what is the technological basis for the Azure DocumentDB service? SQL Server?

• Could not find default endpoint element

  - by edosoft

  I've added a proxy to a webservice to a VS2008/.NET 3.5 solution. When constructing the client .NET throws this error: Could not find default endpoint element that references contract 'IMySOAPWebService' in the service model client configuaration section. This might be because no configuaration file was found for your application or because no end point element matching this contract could be found in the client element Searching for this error tells me to use the full namespace in the contract. Here's my app.config with full namespace: <client> <endpoint address="http://192.168.100.87:7001/soap/IMySOAPWebService" binding="basicHttpBinding" bindingConfiguration="IMySOAPWebServicebinding" contract="Fusion.DataExchange.Workflows.IMySOAPWebService" name="IMySOAPWebServicePort" /> </client> I'm running XP local (I mention this because a number of Google hits mention win2k3) The app.config is copied to app.exe.config, so that is also not the problem. Any clues?

• Unique keys for Sphinx along three vectors instead of two

  - by Brendon Muir

  I'm trying to implement thinking-sphinx across multiple 'sites' hosted under a single rails application. I'm working with the developer of thinking-sphinx to sort through the finer details and am making good progress, but I need help with a maths problem: Usually the formula for making a unique ID in a thinking-sphinx search index is to take the id, multiply it by the total number of models that are searchable, and add the number of the currently indexed model: id * total_models + current_model This works well, but now I also through an entity_id into the mix, so there are three vextors for making this ID unique. Could someone help me figure out the equation to gaurantee that the id's will never collide using these three variables: id, total_models, total_entities The entity ID is an integer. I thought of: id * (total_models + total_entities) + (current_model + current_entity) but that results in collisions. Any help would be greatly appreciated :)

• Mixing Transaction Script pattern with DDD/CQRS

  - by Herman

  Hi all, Here is the situation, in order to support our legacy system, we need to insert to a table whenever a user logs in. This is basically an CRUD operation, so it doesn't really make sense to create repository/entity/command/event for this since this doesn't tie to any business rules at all. The only benefit to create a CQRS command is that this database write can happen asynchronously under that model. Which is a better route to take? Use CQRS, and then call a stored proc. when handling that command? Just call database directly in the controller (I am using asp.net mvc)

• Weird problem cucumber behaving differently when run with the debugger

  - by James

  When I run a cucumber test it executes the code thinking that a collection obtained inside of a controller via a has_many relationship on a model is empty when it isn't. I ran this same test but with the debugger turned and a breakpoint before the collection is used. When I print collection in the debugger at this breakpoint the collection is as it should be (not empty). Then I continue and the test executes as it should. With no debugger and breakpoints though, the test exectues as though the collection is empty. Has anyone had a problem like this/what did you do to fix it?

• How to pre-check checkboxes in formtastic

  - by trustfundbaby

  I have a form I'm trying to set up ... Users can have many posts, and each post can have many people watching it. The Watch model is set up polymorphically as 'watchable' so it can apply to different types of models. It has a user_id, watchable_id, watchable_type and timestamps as attributes/fields. This is soley so that when people comment on a post, users watching the post can get an email about it. What I'm trying to do is show the user a list of users that they can tag on each post, which is not problem. This is what I'm using right now http://pastie.org/940421 The problem with this, is that when you go to edit an update/post ... all the checkboxes are prechecked ... I want it to pre-check only users who are currently watching the post.

• How do I set default values on new properties for existing entities after light weight core data migration?

  - by Moritz

  I've successfully completed light weight migration on my core data model. My custom entity Vehicle received a new property 'tirePressure' which is an optional property of type double with the default value 0.00. When 'old' Vehicles are fetched from the store (Vehicles that were created before the migration took place) the value for their 'tirePressure' property is nil. (Is that expected behavior?) So I thought: "No problem, I'll just do this in the Vehicle class:" - (void)awakeFromFetch { [super awakeFromFetch]; if (nil == self.tirePressure) { [self willChangeValueForKey:@"tirePressure"]; self.tirePressure = [NSNumber numberWithDouble:0.0]; [self didChangeValueForKey:@"tirePressure"]; } } Since "change processing is explicitly disabled around" awakeFromFetch I thought the calls to willChangeValueForKey and didChangeValueForKey would mark 'tirePresure' as dirty. But they don't. Every time these Vehicles are fetched from the store 'tirePressure' continues to be nil despite having saved the context.

• Can't Instantiate Windsor Custom Component Activator

  - by jeffn825

  Hi, I'm getting an exception calling Resolve: KernelException: Could not instantiate custom activator Inner Exception: {"Constructor on type 'MyProj.MyAdapter`1[[MyProj.MyBusinessObject, MyAsm, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null]]' not found."} There's definitely a public parameterless constructor there (and I've verified this using reflection at runtime)...so I figure the problem might have to do with the fact that it's generic? I've tried getting the component model object and setting RequiresGenericArguments to true, but that hasn't gotten me anywhere. Any help would be much appreciated! Thanks.

• Rails best practice on conditional parameters in a controller action

  - by randombits

  I have a controller create action looks for one or more parameters in the following ruleset. Let's say we have two parameters, foo and bar. The rules are the following: 1) if foo doesn't exist in the parameter list, bar must. 2) if bar doesn't exist in the parameter list, foo must. 3) they can both co-exist. they can't both be omitted (that's redundant with my rules above :) ) Can anyone show an example in Rails on how this is handled in the controller? Should I use a before_filter? Would appreciate some guidance as this isn't something that ActiveRecord validates.. so I'd need to build an error message to the user directly from controller logic, not model logic. For bonus points, I output the error in XML, so if you can show how that's done, that'd be great. Hypothetically let's call the resource "Lorem", so it is created via http://foo/lorem.xml and we have lorem_controller.rb.

• Is there a way to circumvent CA1726:UsePreferredTerms?

  - by klausbyskov

  I have a problem with the code analysis rule CA1726:UsePreferredTerms. Our business domain has two crucial concepts named Case and Flag. According to CA, it's apparently a deadly sin to use these names, however I really don't care since, as I said, they are crucial concepts in our domain model. CA complains not only about the type declarations but about every method parameter-name aswell. So does anyone know if there is a workaround other than adding loads of suppressions or disabling the rule altogether? Could I add the names to a custom dictionary?

• Proper way to build a data Repository in ASP.NET MVC

  - by rockinthesixstring

  I'm working on using the Repository methodology in my App and I have a very fundamental question. When I build my Model, I have a Data.dbml file and then I'm putting my Repositories in the same folder with it.... IE: Data.dbml IUserRepository.cs UserRepository.cs My question is simple. Is it better to build the folder structure like that above, or is it ok to simply put my Interface in with the UserRepository.cs? Data.dbml UserRepository.cs              which contains both the interface and the class Just looking for "best practices" here. Thanks in advance.

• RoR - Paperclip - How to set minimal width of an attachement

  - by sNiCKY

  Hi, my layout's requirement is to keep all thumbnails at 80px height, not higher, not smaller. In my model I set the style to :thumb= "500x80", so basically almost every picture which is not too wide gets its perfect miniature with 80px height. Sometimes, however, my pictures are narrow and high, so the thumb can have unclickable dimensions of like 5x80. So I dont want to crop pictures as long as thumbnails are not getting crazy narrow, but I think I can make a little sacrifice and crop them if thumb's width is getting smaller than 25px. So my questions is - is it possible in paperclip to set minimal proportions of a picture by which the style will be "500x80" and beyond that it will turn to sth like "25x80#"?
