  • core data editor problems

    - by Peyman
    I was recommended by someone in Stack Overflow to use Core Data Editor http://christian-kienle.de/CoreDataEditor/ to manage the sqlite persistent store. However the latest version (3.0) crashes on launch everytime. Older versions load but I see nothing when i point the config to the persistent store and the object model directories. There is no documentation either. can someone point me to the right place to sort this problem? I am trying to find a more manageable way to coordinate core data development than sqlite consoles. thank you

  • Design of Business Layer

    - by Adil Mughal
    Hi, We are currently revamping our architecture and design of application. We have just completed design of Data Access Layer which is generic in the sense that it works using XML and reflection to persist data. Any ways now we are in the phase of designing business layer. We have read some books related to Enterprise Architecture and Design so we have found that there are few patterns that can be applied on business layer. Table Pattern and Domain Model are example of such patterns. Also we have found Domain Driven Design as well. Earlier we decided to build Entities against table objects. But we found that there is difference in Entities and Value Objects when it comes to DDD. For those of you who have gone through such design. Please guide me related to pattern, practice and sample. Thank you in advance! Also please feel free to discuss if you didn't get any point of mine.

  • Branch by abstraction: Are there "examples" of how it can be done?

    - by Philipp Keller
    Having read Martin Fowlers "Feature Branch" and Flickrs "Flipping Out" (http://www.liip.to/flippingout) I guess there are a few guys out there who do: all (or most) development on Trunk release Trunk regularly (assuming updating your web site) not-yet-approved or not-yet-finished features should not be visible/have no impact on the regular user I've got 2 questions: granted - Flickr's article seems to work for "frontend code". But how is it cleaned up? Don't the ifs pile up? how does this work for the more "backend part"? Thinking of database changes, or model refactoring. Working with ifs doesn't seem to work - and copy-pasting classes for small adaptions also seems awkward. Are there any articles out there answering these 2 questions?

  • Arbitrary attributes error with has_one association and Factory Girl

    - by purpletonic
    I'm trying to build a basic shopping cart for a Rails app I'm working on. Nothing special, - the shopping cart has many line_items - each line_item has_one product associated and a quantity with it class Cart < ActiveRecord::Base attr_accessible :line_items has_many :line_items, :dependent => :destroy end class LineItem < ActiveRecord::Base attr_accessible :quantity, :product belongs_to :cart has_one :product end I'm trying to use RSpec to test this association, but i'm doing something wrong as I'm getting an error that says: DEPRECATION WARNING: You're trying to create an attribute 'line_item_id'. Writing arbitrary attributes on a model is deprecated, and I'm not sure why. In my factories.rb file I'm defining the line_item factory as follows: factory :line_item do quantity { Random.rand(1..5) } product end factory :cart do factory :cart_with_two_line_items do ignore do line_item_count 2 end after(:create) do |cart, evaluator| FactoryGirl.create_list(:line_item, evaluator.line_item_count, cart_id: cart) end end end Any pointers where I'm going wrong, it's probably something basic, but I'm still quite new to Rspec. Thanks in advance.

  • EXTEND_MODEL_CASES SQL 2005 workaround

    - by user282382
    Hi, I have a time series based mining model in SQL 2005 Analysis Serveries. I understand in 2008 you can do what if analysis by using EXTEND_MODEL_CASES with a Natural Prediction Join. I'm looking for a workaround or some method of doing the same thing but with 2005. My time series has 3 inputs, and one predict_only. I'd like to use the prediction function to see what types of prediction it makes for 6-12 time intervals in the future with inputs in a separate table. Is there any way to do this or something similar? Thanks

  • iPhone: Core Data: Updating a pre-filled database in future app versions.

    - by Cuzog
    I am creating an app with a database of information that needs to be pre-filled. This data will change in future versions. In the same database, I also need to store user editable information since that user edited data directly relates to the pre-filled data. My question is, if I'm pre-filling the database by creating a duplicate data model in a second app and copying over the core data file before release, how would I handle updates to that data in future versions of the app without destroying the user's existing data? Do the core data migration methods handle this, or must I write custom methods to programatically handle the merge at first app launch?

  • OpenGL Color Interpolation across vertices

    - by gutsblow
    Right now, I have more than 25 vertices that form a model. I want to interpolate color linearly between the first and last vertex. The Problem is when I write the following code glColor3f(1.0,0.0,0.0); vertex3f(1.0,1.0,1.0); vertex3f(0.9,1.0,1.0); . .`<more vertices>; glColor3f(0.0,0.0,1.0); vertex3f(0.0,0.0,0.0); All the vertices except that last one are red. Now I am wondering if there is a way to interpolate color across these vertices without me having to manually interpolate color natively (like how opengl does it automatically) at each vertex since, I will be having a lot more number of colors at various vertices. Any help would be extremely appreciated. Thank you!

  • Extending Django-tagging, adding extra field to each tag?

    - by victorhooi
    heya, We're coding together a Django app to handle reviews of newspaper articles. Each newspaper article model will an arbitrary number of tags associated with it. Also, each tag will have an optional ranking (0 to 10). I was thinking of using django-tagging to do this (http://code.google.com/p/django-tagging/), but I'm not sure of the best way to add the ranking to the system. Should I extend django-tagging somehow? (Not sure if this is possible, without changing django-tagging's actual code?). Or is there a better way of achieving this? Cheers, Victor

  • Why does ASP.NET web site reference assembly from GAC, when adding local reference?

    - by Konstantin
    When you use ASP.NET web site (instead of web application model) and add reference to an assembly from local folder, Visual Studio, it seems, understands that this local assembly is also in GAC and so does NOT copy this assembly to bin folder (as it does with non-GAC assemblies), but simply adds new record in web.config file. Why such a behaviour? Is it possible to force copy to bin folder (I need this since .dll is not on target environment)? I can add assembly to bin folder as file and it will work, but in this case bin folder contents will be in source control, which is not good.

  • What is the autoload class names structure, for the root "library" dir in a Zend Framework 1.10.2 pr

    - by Doron
    I have a project I created with Zend Framework 1.10.2. I usually use the application/models directory for new model files I create, and the auto loading is fine, so for example - My_Model_SampleClass is located application/models/SampleClass.php. However, I have just created a custom Exception class, and it does not fit in the models directory inside the application dir (at least the way I see it, I could be logically wrong), so I've created it in the root "library" dir, but I can't seem to find the correct class name + file name to use, so auto loading will be done correctly. BTW, I use a namespace for all custom classes I use, let's assume it's "My".

  • Can Entity Framework be used for the purpose of entity/schema definition at application runtime?

    - by Kabeer
    Hello. Can 'Entity Framework' be used for the purpose of entity definition at application runtime? Ok, to make it simple, here is what I want to achieve: My application is a product. I should be able to define entities at runtime on the basis of inputs gathered from an 'authoring' user (in effect this means 'model first' approach). These entities are of course persistable. Further, after having defined the entities and their relationships, I should be able to make complex queries across them for many reasons, including reports. Is the above possible and how? So far what I have realized is that there is a dependency on Visual Studio.

  • What's an elegant way to conditionally add a class to an HTML element in a view?

    - by ryeguy
    I occasionally have to add a class to an html element based on a condition. The problem is I can't figure out a clean way of doing it. Here's an example of the stuff I've tried: <div <%= if @status = 'success'; "class='ok'"; end %>> some message here </div> OR <% if @status == 'success' %> <div class='success'> <% else %> <div> <% end %> some message here </div> I don't like the first approach because it's crowded looking and hard to read. I don't like the second approach because the nesting is screwed up. It'd be nice to put it in the model, (something like @status.css_class), but that doesn't belong there. What do most people do?

  • python object AttributeError: type object 'Track' has no attribute 'title'

    - by ccwhite1
    I apologize if this is a noob question, but I can't seem to figure this one out. I have defined an object that defines a music track (NOTE: originally had the just ATTRIBUTE vs self.ATTRIBUTE. I edited those values in to help remove confusion. They had no affect on the problem) class Track(object): def __init__(self, title, artist, album, source, dest): """ Model of the Track Object Contains the followign attributes: 'Title', 'Artist', 'Album', 'Source', 'Dest' """ self.atrTitle = title self.atrArtist = artist self.atrAlbum = album self.atrSource = source self.atrDest = dest I use ObjectListView to create a list of tracks in a specific directory ....other code.... self.aTrack = [Track(sTitle,sArtist,sAlbum,sSource, sDestDir)] self.TrackOlv.AddObjects(self.aTrack) ....other code.... Now I want to iterate the list and print out a single value of each item list = self.TrackOlv.GetObjects() for item in list: print item.atrTitle This fails with the error AttributeError: type object 'Track' has no attribute 'atrTitle' What really confuses me is if I highlight a single item in the Object List View display and use the following code, it will correctly print out the single value for the highlighted item list = self.TrackOlv.GetSelectedObject() print list.atrTitle

  • Authlogic Multiple Password Validation

    - by Hock
    Hello, I'm using Authlogic to manage my user sessions. I'm using the LDAP add-on, so I have the following in my users model acts_as_authentic do |c| c.validate_password_field = false end The problem is that recently I found out that there will be some users inside the application that won't be part of the LDAP (and can't be added!). So I would need to validate SOME passwords against the database and the others against the LDAP. The users whose password will be validated against the database will have an specific attribute that will tell me that that password will be validated in my database. How can I manage that? Is it possible that the validate_password_field receives a "variable"? That way I could create some method that will return true/false depending on where the password validation will be done? Thanks!

  • Adding custom context menu items to an Outlook MailItem using Outlook 2007 VSTO 3.0

    - by cbass
    Hi I've been trying to figure out how to create a context menu in VSTO 2007. I'm hoping that is possible. When I make this call. Dim commandBar As Microsoft.Office.Core.CommandBar = _word.CommandBars("Text") I get the following error. This object model command is not available in e-mail. I've look all over and from what I can tell it's not possible to add to the context menu in Office 2007. This doesn't seem right. I've also tried this event without any luck since it isn't being fired when right clicking on the MailItem ItemContextMenuDisplay(ByVal commandBar As Microsoft.Office.Core.CommandBar, ByVal selection As Microsoft.Office.Interop.Outlook.Selection) Hoping that someone can help. Thanks in advance.

  • How should objects be in a Java game.

    - by Gabriel A. Zorrilla
    EDIT: i just deleted the entire post and reformulated the question to be more generic. I want to do a simple strategy game: map, units. Map: one class. Units: another class, self drawn. Simple questions: How does an unit should redraw itself on the map. A unit should be a JPanel or similar Swing component (just to be able to manage them as an entity with its own mousehandlers) or can be another thing, without neglecting the fact that it should be an autonomous object with its own action handlers and fields. Is this map-units model correct of a simple game that would help me to learn in a fun way Java and OOP fundamentals. Thats it!

  • file_column not creating files, just empty tmp directory

    - by Yanaek
    Up to the end of December 2009 everything worked fine, so i assume that after some upgrades on servers (Ubuntu 8.10 and second Ubuntu 9.10) something stopped working. Model: class Product < ActiveRecord::Base belongs_to :category file_column :thumbnail, :magick = { :geometry = "150x100" } there is of course table 'products' in database, and it has column 'thumbnail' what's interesting that File actually is uploaded to server, it goes to the /tmp directory under RackMultipartXXXX-0 name, and it is unmodified image. The problem is, that then this file is not moved to 'tmp' dir under RAILS_ROOT/public/product/ nor the 'XX' (where xx means ID of a product) under public/product also. i don't know what to do, i spend few HOURS trying different versions of file_column, also trying to make new, test rails application only from scaffold, but then, in this new application problem was the same

  • Naming convention for the primary key in a Table

    - by kwokwai
    Hi all, I am learning the Model relationship types in cakephp. I have built twotables and in one of the Table A, I got these fields in it: Table A {postID, topic, content} Table B {replyID, content, postID} And when I ran the web page, a bunch of error related to SQL popped up saying that cakephp couldn't find post_id. It is weird that I have already declared the $primaryKey to be using postID in the tableA.php under Models folder, but cakephp seemed want me to change the ID field to post_id instead of postID, because the error disappeared after I have changed the primaryKey to post_id. ANy ideas?

  • 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. All of a sudden I'm now dumbfounded by an error. 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 once specific relationship, I get this error: *** -[NSCFNumber entity]: unrecognized selector sent to instance 0x3f26f50 Has anyone ever encountered anything like this before? I've tried clean all targets, restarting everything, even changing the model to the relationship in question is a to-one instead of a to-many. Nothing makes any difference.

  • 3d user experience with HTML5 and Javascript

    - by chako
    I've to build a 3D user experience with HTML5 and any required JS library which provides such functionality. 3D scene consists of a cylindrical pipe and surface. It has 360 degree rotation and can zoom in and out. As user selects a parameter, specific value of that parameter at various depth of pipe in surface should display. I've searched for HTML5 3d and JS libraries and found three.js could help for this.Also found this useful presentation on HTML 3d engine: http://projects.mariusgundersen.net/OnGameStart/#1 .But as this is my first time with HTML5 3d modeling, how should I initiate to build ? What parameters should be considered ? Which tools and libraries would best fit for such requirements ? I would like to create a 3d model using HTML5 and JS 3d engine as shown in the 1st image.

  • Django : json serialize a queryset which uses defer() or only()

    - by PlanetUnknown
    Now I've been using json serializer and it works great. I had to modify my queries where I started using the only() & defer() filters, like so - retObj = OBJModel.objects.defer("create_dt").filter(loged_in_dt__gte=dtStart) After I've done the above, suddenly the json serializer is returning empty fields - {"pk": 19047, "model": "OBJModel_deferred_create_dt", "fields": {}} If I remove the defer(), the serializer gives all the data correctly. import json from django.utils import simplejson from django.core import serializers json_serializer = serializers.get_serializer("json")() retObj = OBJModel.objects.defer("create_dt").filter(loged_in_dt__gte=dtStart) json_serializer.serialize(retObj, ensure_ascii=False) I've scratched my head on this for a while now. Any insight would be great. NOTE : I am using django 1.1
