• iPhone - Create not persistant entities in core data

  - by ncohen

  Hi everyone, I would like to use entity objects but not store them... I read that I could create them like this: myElement = (Element *)[NSEntityDescription insertNewObjectForEntityForName:@"Element" inManagedObjectContext:managedObjectContext]; And right after that remove them: [managedObjectContext deleteObject:myElement]; then I can use my elements: myElement.property1 = @"Hello"; This works pretty well even though I think this is probably not the most optimal way to do it... Then I try to use it in my UITableView... the problem is that the object get released after the initialization. My table becomes empty when I move it! Thanks

• Core Data - insertNewObjectForEntityForName debug

  - by Snow Crash

  I'm trying to figure out why insertNewObjectForEntityForName is not working. I assume it's something to do with my data model but can't be sure. Xcode does not report any errors nor does it crash. All I get is the first log statement output to the console. NSLog(@"Get here..."); Task *task = (Task *)[NSEntityDescription insertNewObjectForEntityForName:@"Task" inManagedObjectContext:insertionContext]; NSLog(@"but never get here..."); Any suggestions as to how I can work out what the problem is?

• Core Data not-reverse relationship subquery

  - by user561485

  Hi, I have the following entities in CoreData: Village - villageID Bookmark - (relation) village There are multiple villages with each an unique villageID. I have a entity Bookmark which only has a relation to a Village entity; it isn't possible to make a reverse relation. Now I would like to get the village entities where there exists a Bookmark relation. I've red something about subqueries, but I can't get it right for this situation. It must be something like: Village.villageID IN (Bookmark.village.villageID) It isn't possible to get first all the Bookmarks and then loop to get all the Villages, because of the design of the framework. Can this be done in CoreData (I presume the answer is "Yes, of course!") and how?

• How is Core Data detecting the conflicts, actually?

  - by brainfrog

  Apple says about -detectConflictsForObject: If on the next invocation of save: object has been modified in its persistent store, the save fails. This allows optimistic locking for unchanged objects. Conflict detection is always performed on changed or deleted objects. So what does this mean? If I simply modify an managed object and then save the context, there is always a conflict detection happening? Does this conflict detection simply compare the timestamps of the "records" to see if the "new" data is actually "old"? Is that a conflict?

• Core Data-Linking one-to-many relationships

  - by Stelmate

  I have a one-to-many relationship where each department has many employees. When I create a new employee object I just link it to the parent department manually by setting the property to the instance of the department I have fetched from my fetch request. However, this seems to be improper because when I try to access the set of employees from the department by simply accessing the .employees property on my department object instance it returns a 0 count. Isn't the fault suppose to fire once I access a property? Am I linking my parent/child objects incorrectly?

• AND NSPedicate on Core Data relationships

  - by jesse001

  I'm having trouble compounding NSPredicate with AND, although using OR works fine. Imagine 2 entities, Doctor and Patient. Doctors can have many patients and patients many doctors. I want to find doctors that, say, have both person1 and person2 as patients. I expected this to work but it returns none. NSPredicate *predicate = [NSPredicate predicateWithFormat:@"ANY patients matches 'person1&&person2'"]; If I change && to ||, I get all doctors that have person1 or person2 as I'd expect. Thanks in advance for your help.

• Using iPhone Core Data to many Relationship

  - by BLeB

  When I define a to many relationship between entities in Xcode and then generate the data class from the entity I get a header with the following methods defined: @interface PriceList (CoreDataGeneratedAccessors) - (void)addItemsObject:(PriceListItem *)value; - (void)removeItemsObject:(PriceListItem *)value; - (void)addItems:(NSSet *)value; - (void)removeItems:(NSSet *)value; @end When I attempt to call addItemsObject with the following code a doesNotRecognizeSelector exception is thrown. PriceListItem *item = [NSEntityDescription insertNewObjectForEntityForName:@"PriceListItem" inManagedObjectContext:managedObjectContext]; item.cat = [attributeDict valueForKey:@"c"]; item.sel = [attributeDict valueForKey:@"s"]; [self addItemsObject:item]; From what I have read I do not have to implement these methods and that they are generated at runtime. Any ideas?

• Improving the efficiency of multiple concurrent Core Animation animations

  - by Alex

  I have a view in my app that is very similar to the month view in the built-in Calendar app. There's a subview that holds the individual cells (a custom UIView subclass that draws text into its layer), and when the user navigates to the next "month", I create the new cells and slide the view to show them. When the animation stops, I remove the old, hidden cells and set things up so it's ready to go for the next animation. This all works nicely. However, I'd like to animate the cells' text color, as in the Calendar app, so that the outgoing ones transition to a lighter color and the incoming ones transition to a darker color. The problems is that I can have as many as 70 cells, so doing individual animations is very slow -- between 5-10 fps on my iPhone 3GS. I'm trying to find a less computationally intense way of doing this. My reading of the Shark results is that the majority of the time is spent redrawing the text for each frame for each frame. This makes sense, since text rendering is hardly the cheapest operation. I've considered creating a second view -- one holding the "outgoing" state and one holding the "incoming" state and using a single opacity animation to gradually reveal the updated cells while both are sliding. I'm concerned that instead of having 70 cells, I'll have 140, which seems like a lot of views. So, is that too many views or would there be a better way of doing this?

• Core Data to-many relationship in code

  - by Jan Bezemer

  I have three entities: Session, User and Test. A session has 0-many users and a user can perform 0-6 tests. (I say 0 but in the real application always at least 1 is required, at least 1 user for a session and at least 1 test for a user. But I say 0 to express an empty start.) All entities have their own specific data attributes too. A user has a name, A session has a name, a test has six values to be filled in by the user, and so on. But my issue is with the relationships. How do I set multiple users and have them added to one session (same goes for multiple tests for one user). How do I show the content in a right way? How do I show a session that has multiple users and these users having completed multiple tests? Here's my code so far with regard to issue 1: Session *session = [NSEntityDescription insertNewObjectForEntityForName:@"Session" inManagedObjectContext:context]; session.name = @"Session 1"; User *users = [NSEntityDescription insertNewObjectForEntityForName:@"User" inManagedObjectContext:context]; users.age = [NSNumber numberWithInt:28]; users.session = session; //sessie.users = users; [sessie addUserObject:users]; With regard to issue 2: I can log the session, but I can't get the user(s) logged from a session. NSFetchRequest *fetchRequest = [[NSFetchRequest alloc] init]; NSEntityDescription *entity = [NSEntityDescription entityForName:@"Session" inManagedObjectContext:context]; [fetchRequest setEntity:entity]; NSArray *fetchedObjects = [context executeFetchRequest:fetchRequest error:&error]; for (Session *info in fetchedObjects) { NSLog(@"Name: %@", info.name); NSLog(@"Having problems with this: %@",info.user); //User *details = info.user; //NSLog(@"User: %@", details.age); }

• I'm an experienced PHP programmer, how would it be for me to learn and use Django and Ruby on Rails?

  - by João Paulo Apolinário Passos

  I'm an experienced PHP programmer, I still have lots to learn but I consider myself experienced. I sometimes use pure PHP and sometimes some framework like CodeIgniter. I always wanted to learn new technologies like Python and Ruby, and their best frameworks for web are Django and Ruby on Rails, but I want to ask to persons like me who migrated from PHP to some of this technologies if is it worth it; Thank you

• Add Microsoft Core Fonts to Ubuntu

  - by Matthew Guay

  Have you ever needed the standard Microsoft fonts such as Times New Roman on your Ubuntu computer?  Here’s how you can easily add the core Microsoft fonts to Ubuntu. Times New Roman, Arial, and other core Microsoft fonts are still some of the most commonly used fonts in documents and websites.  Times New Roman especially is often required for college essays, legal docs, and other critical documents that you may need to write or edit.  Ubuntu includes the Liberation alternate fonts that include similar alternates to Times New Roman, Arial, and Courier New, but these may not be accepted by professors and others when a certain font is required.  But, don’t worry; it only takes a couple clicks to add these fonts to Ubuntu for free. Installing the Core Microsoft Fonts Microsoft has released their core fonts, including Times New Roman and Arial, for free, and you can easily download these from the Software Center.  Open your Applications menu, and select Ubuntu Software Center.   In the search box enter the following: ttf-mscorefonts Click Install on the “Installer for Microsoft TrueType core fonts” directly in the search results. Enter your password when requested, and click Authenticate. The fonts will then automatically download and install in a couple minutes depending on your internet connection speed. Once the install is finished, you can launch OpenOffice Writer to try out the new fonts.  Here’s a preview of all the fonts included in this pack.  And, yes, this does included the infamous Comic Sans and Webdings fonts as well as the all-important Times New Roman. Please Note:  By default in Ubuntu, OpenOffice uses Liberation Serif as the default font, but after installing this font pack, the default font will switch to Times New Roman. Adding Other Fonts In addition to the Microsoft Core Fonts, the Ubuntu Software Center has hundreds of free fonts available.  Click the Fonts link on the front page to explore these, and install the same as above. If you’ve downloaded another font individually, you can also install it easily in Ubuntu.  Just double-click it, and then click Install in the preview window. Conclusion Although you may prefer the fonts that are included with Ubuntu, there are many reasons why having the Microsoft core fonts can be helpful.  Thankfully it’s easy in Ubuntu to install them, so you’ll never have to worry about not having them when you need to edit an important document.

• Do NOT remove the reference to System.Core from your VS2010 Project

  - by Lee Brandt

  One of the things I routinely do when adding a new class library project, is remove all references and just add them back in as I need them. That is NOT a good idea for Visual Studio 2010. When I DID need System.Core, and went to add it back, this is what I got: "A reference to 'System.Core' could not be added. This component is automatically referenced..." After some Googling I found this article: http://connect.microsoft.com/VisualStudio/feedback/details/525663/cannot-remove-system-core-dll-reference-from-a-vs2010-project It tells you to add it back manually. Here is the part that needs back in the project file. After the last PropertyGroup node, add this node:   <ItemGroup>     <Reference Include="System.Core" />   </ItemGroup> You should be good to go again. Hope this helps.

• New SQL Server 2012 per core licensing – Thank you Microsoft

  - by jchang

  Many of us have probably seen the new SQL Server 2012 per core licensing, with Enterprise Edition at $6,874 per core super ceding the $27,495 per socket of SQL Server 2008 R2 (discounted to $19,188 for 4-way and $23,370 for 2-way in TPC benchmark reports) with Software Assurance at $6,874 per processor? Datacenter was $57,498 per processor, so the new per-core licensing puts 2012 EE on par with 2008R2 DC, at 8-cores per socket. This is a significant increase for EE licensing on the 2-way Xeon 5600...(read more)

• I have a server running Windows 2008 R2 Core and it needs to hosts either SVN or GIT

  - by Jason Adams

  The server allocated for our cross platform projects (both Mac & PC) source repository is running Win2008R2 Core. We're really happy with its stability and we aren't interested in moving over to non-core. We need to get either SVN or GIT installed on the aforementioned box in the shortest amount of steps. We know the advantages/disadvantages of both systems. That being said, we don't care which one we use, we're just are looking for the path of least resistance on setting up a repository on a machine running R2 core.

• Django - How to do CSFR on public pages? Or, better yet, how should it be used period?

  - by orokusaki

  After reading this: http://docs.djangoproject.com/en/dev/ref/contrib/csrf/#how-to-use-it I came to the conclusion that it is not valid to use this except for when you trust the person who is using the page which enlists it. Is this correct? I guess I don't really understand when it's safe to use this because of this statement: This should not be done for POST forms that target external URLs, since that would cause the CSRF token to be leaked, leading to a vulnerability. The reason it's confusing is that to me an "external URL" would be on that isn't part of my domain (ie, I own www.example.com and put a form that posts to www.spamfoo.com. This obviously can't be the case since people wouldn't use Django for generating forms that post to other people's websites, but how could it be true that you can't use CSRF protection on public forms (like a login form)?

• Django: A Result Specific Numeration for Pagination.

  - by TheLizardKing

  Simply put I want what http://www.reddit.com/ and http://news.ycombinator.com/ have to the left of every link. A numerated link starting with 1 and continuing to the next page by means of pagination. I really enjoy using generic views and their built-in pagination for Django and it seems to allow me access to these values if I was on page 3 with 2 items per page. {'MEDIA_URL': ''} {'LANGUAGES': '<<languages>>', 'LANGUAGE_BIDI': False, 'LANGUAGE_CODE': 'en-us'} {'debug': True, 'sql_queries': '<<sql_queries>>'} {'messages': [], 'perms': <django.core.context_processors.PermWrapper object at 0xadedeec>, 'user': <User: thelizardking>} {'first_on_page': 5, 'has_next': True, 'has_previous': True, 'hits': 7, 'is_paginated': True, 'last_on_page': 6, 'links_list': [<Link: Funky Town>, <Link: Apple Jax>], 'next': 4, 'page': 3, 'page_obj': <Page 3 of 4>, 'page_range': [1, 2, 3, 4], 'pages': 4, 'paginator': <django.core.paginator.Paginator object at 0xadf914c>, 'previous': 2, 'results_per_page': 2} I know there is an add filter for templates but that's as close as I think I can get and that really doesn't do what I want. Am I going to have to use a custom template filter here or is there something I am not seeing?
