• What is the best software to write and organize written copy / content for a website?

  - by johnqtaxpayer

  I'm a newbie product manager, looking for tips on how to write and organize text copy for my company's website. I need to be able to prepare the content for our public site and turn it over to the web designer who publishes it to our live site. I want our UI team to be able to quickly glance at the copy I write and immediately know where on the page I intend for it to go. Currently, I'm using microsoft word to write and color code different text to signify where I want specific text to go. It is difficult for the UI guy to immediately know if something goes into the nav bar or into a header or a description below a header. In addition to that, it would be helpful for me to be able to write the copy in such a way that the web designer could copy and paste it into the XHTML without having to go back and manually replace special punctuation characters with the XHTML entities. What software is out there that will allow a comprehensive solution to these web copywriting issues?

• Selecting one object from a one-to-many relationship in Hibernate

  - by Nick Thomson

  I have two tables: Job job_id, <other data> Job_Link job_link_id, job_id, start_timestamp, end_timestamp, <other data> There may be multiple records in Job_Link specifying the same job_id with the start_timestamp and end_timestamps to indicate when those records are considered "current", it is guaranteed that start_timestamp and end_timestamp will not overlap. We have entities for both the Job and Job_Link tables and defining a one-to-many relationship to load all the job_links wouldn't be a problem. However we'd like to avoid that and have a single job_link item in the Job entity that will contain only the "current" Job_Link object. Is there any way to achive that?

• How to generate JPA 2.0 metamodel?

  - by yamsha

  In the spirit of type safety associated with the CriteriaQuery JPA 2.0 also has an API to support Metamodel representation of entities. Is anyone aware of a fully functional implementation of this API (to generate the Metamodel... as opposed to creating the metamodel classes manually)? It would be awesome if someone also knows the steps for setting this up in Eclipse (I assume it's as simple as setting up an annotation processor, but you never know). EDIT: Just stumbled across Hibernate JPA 2 Metamodel Generator . But the issue remains since I can't find any download links for the jar

• ORM Against a Service-Wrapped Data Source

  - by blaster

  We are tasked with migrating an existing set of entities (currently POCOs persisted with NHibernate against an MSSQL database) to now persist to some kind of web service (yet to be built, either RESTful or SOAP-based, and that we control). I like how NHibernate encapsulates the persistence concerns and lets us maintain a logic-rich, persistence-agnostic domain model. Is there any way to make NHibernate talk to a web service at the back end instead of a SQL database directly? In other words, can "service instead of SQL database" be treated as a persistence implementation detail and allow us to continue to use NHibernate? Am I asking the right question? :)

• Alt attribute encoding with JavaScript

  - by MainMa

  Hi, Html entities must be encoded in alt attribute of an image in HTML page. So <img id="formula" alt="A &rarr; B" src="formula.png" /> will work well. On the other hand, the same JavaScript code will not work document.getElementById('formula').alt = 'A &rarr; B'; and will produce A &rarr; B instead of A → B. How to do it through JavaScript, when it is not possible to put the special (unencoded) characters in the source code?

• JPA @version - can it be used to calcualate version of a table entry

  - by OpenSource

  Hi, Please consider the following table (created using a corresponding entity) request ------- id requestor type version items 1 a t1 1 5 2 a t1 2 3 3 b t1 1 2 4 a t2 1 4 5 a t1 3 9 The above is what I want to achieve. The version field is a calculated field others are user provided. Basically the request's version needs to be calculated based on the combination of requestor and the type. The first occurance with a given combination will have a version 1 then version 2 and so on. I tried various things using @version on a different entity with just the three columns and joining the two entities using ManytoOne etc but I'm not able to get to the desired outcome. I dont want to confuse you with the things I tried. Since the objective is simple there should be an easier way I suppose? Can you please help? - any help greatly appreciated! thanks in advance

• Can I bypass an intermediate object in hibernate

  - by Jherico

  I have top level entities TRACK, MEDIA_GROUP and MEDIA, each with an integer primary key. I also have a join table from TRACK to MEDIA_GROUP which is 1:1 and MEDIA has a FK column into MEDIA_GROUP. I'm trying to find a way in hibernate to map a collection of Media directly into the Track object, bypassing the creation of a MediaGroup object. Basically I want to turn this: TRACK <-> MEDIA_TRACK_MAP <-> MEDIA_GROUP <-> MEDIA into this: TRACK <-> MEDIA_TRACK_MAP <-> MEDIA But the join column between MEDIA_TRACK_MAP and MEDIA isn't the primary key of MEDIA.

• Accessing CoreData relationships

  - by georgeliquor

  I have the following core data model with two entities: entity "item" which holds name, date, description and a to many relationship "image". image is optional. entity "image" holds url, name and relationship to one item. I load the executed Fetchrequest into this NSArray "entityArray" This is what I do to display my data in a UITableView for example to display title in main cell: NSManagedObject *object = (NSManagedObject *)[entityArray objectAtIndex:indexPath.row]; cell.textLabel.text=[object valueForKey:@"title"]; Now I have no clue how to access my relationship image ([object valueForKey:@"image"]), because it contains more than just a string.

• Why Hibernates ignores the name attribute of the @Column annotation?

  - by svachon

  Using Hibernate 3.3.1 and Hibernate Annotations 3.4, the database is DB2/400 V6R1, running that on WebSphere 7.0.0.9 I have the following class @Entity public class Ciinvhd implements Serializable { @Id private String ihinse; @Id @Column(name="IHINV#") private BigDecimal ihinv; .... } For reasons I can't figure, Hibernate ignores the specified column name and uses 'ihinv' to generate the SQL: select ciinvhd0_.ihinse as ihinse13_, ciinvhd0_.ihinv as ihinv13_, ... Which of course gives me the following error: Column IHINV not in table CIINVHD Did anyone had this problem before? I have other entities that are very alike in the way that they are using # in their database field names and that are part of the PK and I don't have this problem with them.

• Include in enity framework 4

  - by molgan

  Hello I've been using enity framework that came with 3.5sp. And now I've redone things for enityframework 4 and asp.net mvc 2. I've come across something (which worked in my previous version and asp.net mvc 1.0). I have this: public IQueryable<Booking> GetBookings() { return from b in _entities.Bookings.Include("BookingObject") select b; } And in my controller I have: return View("Index", new BookingsViewModel { Bookings = _br.GetBookings().ByDay(DateTime.Today) }); And it doesnt seem to include the "BookingObject"-entity, so I can type like <%= Model.Bookings.BookingObject.BookingObjectName %> in my view. What might be missing here? Do I need to turn something on in the diagram for it to include entities or? /M

• Why would I want to have a non-standard attribute?

  - by dontWatchMyProfile

  The documentation on Core Data entities says: You might implement a custom class, for example, to provide custom accessor or validation methods, to use non-standard attributes, to specify dependent keys, to calculate derived values, or to implement any other custom logic. I stumbled over the non-standard attributes claim. It's just a guess: If my attribute is anything other than NSString, NSNumber or NSDate I will want to have a non-standard Attribute with special setter and getter methods? So, for example, if I wanted to store an image, this would be a non-standard Attribute with type NSData and a special method, say -(void)setImageWithFileURL:(NSURL*)url which then pulls the image data from the file, puts in in an NSData and assigns it to core data? Or did I get that wrong?

• Stop Entity Framework from updating edmx model with a column that isn't needed

  - by TMan

  I have rowguids in all my tables to help with change tracking in all my tables. I don't want/need these tables in my edmx or my entities. However, I do still need to make changes to other things sometimes so everytime i go to update model from database in the edmx it adds all the rowguids in all my tables everytime and i have to manually delete each one. Is there a way to handle this from happening? Is there a way I can maybe edit the T4 to maybe ignore that 'rowguid' column? Database first Entity framework

• 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?

• Hibernate won't autogenerate sequence table

  - by Jason

  I'm trying to use a sequence table to generate keys for my entities. I notice that if I just use the @GeneratedValue(strategy=GenerationType.TABLE) with no explicit generator, Hibernate will automatically create the hibernate_sequences table in my DB if it doesn't exist. This is great. However, I wanted to make some changes to the sequence table, so I created a @TableGenerator like the following: @GeneratedValue(strategy=GenerationType.TABLE, generator="vdat_seq") @TableGenerator(name="vdat_seq", table="VDAT_SEQ", pkColumnName="seq_name", valueColumnName="seq_next_val", allocationSize=1) This works fine if I manually create the VDAT_SEQ table in my schema; Hibernate won't auto-create it anymore. This causes an issue in my unit tests, since I'd rather not have to manually create a table and maintain it on our testing DB. Is there a configuration variable or some other way to get Hibernate to generate the sequence table?

• Doctrine2: Filtering by ManToMany Association

  - by Shroder

  I want to retrieve a collection of objects based on what they are associated to. For example, by a category. This would be a Many to Many relationship. I've been able to achieve that with MEMBER OF, however I need to pass in an array of IDs, opposed to one at a time. I see there is an "IN ()", but it seems to require a subquery, which I would like to avoid. MEMBER OF example: SELECT o FROM Entity\Object1 o WHERE 'CATEGORY_CODE' MEMBER OF o.categories (Edit) This is what I would like to do, but perhaps I'm misunderstanding how entities work in DQL: SELECT o FROM Entity\Object1 o WHERE o.categories.Id IN (id, id, id)

• Delete Entity in Many to Many Relation. Don't get error but entity is not deleted

  - by Shapper

  I have, in EF5, two entities: User and Role. Between User and Role there is a many to many relation. I don't have an entity for the UserRoles database which sets the relation. I have a User and I want to delete a role without loading it from the database. Context context = new Context(); User user = context.Users.First(x => x.Id == 4); user.Roles = new List<Role>(); Role role = new Role { Id = 20 }; context.Roles.Attach(role); user.Roles.Remove(role); context.SaveChanges(); I don't get any error but the role is not removed. Any idea why? Thank you, Miguel

• 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.

  I have two classes, both of which need to be able to call the same instance of entitymanager class Engine { EntityManager::Entitymanager EManager; } And I need to add an object to a vector contained by this particular instance of Engine. What I want to do is be able to add a bullet spawned by the player to the vector that contains all my entities. class Player : Entity { void SpawnBullet() {Engine::EManager.Add(BULLET);} } The above returns this error: error: object missing in reference to ‘Engine::EManager’ How do I resolve this? Any help or pointers in the right direction would be much appreciated!

• How can I double-enhance a class with cglib?

  - by artemb

  Hi there! Here's the code: Patient patient = factory.createPatient(); Enhancer enhancer = new Enhancer(); enhancer.setSuperclass(patient.getClass()); enhancer.setCallback(new DefaultMethodInterceptor(patient)); patient = (Patient) enhancer.create(); assertThat(patient.getFirstName()).isNotNull(); Enhancer enhancer2 = new Enhancer(); enhancer2.setSuperclass(patient.getClass()); enhancer2.setCallback(new DefaultMethodInterceptor(patient)); patient = (Patient) enhancer2.create(); assertThat(patient.getFirstName()).isNotNull(); It fails on the last assert with net.sf.cglib.core.CodeGenerationException: java.lang.reflect.InvocationTargetException-->null ... Caused by: java.lang.reflect.InvocationTargetException ... Caused by: java.lang.ClassFormatError: Duplicate method name&signature in class file my/package/entity/Patient$$EnhancerByCGLIB$$ca1e6685$$EnhancerByCGLIB$$f52743be I ask this because I want to enhance Hibernate's entities, but sometimes it returns already enhanced ones by itself and my second enhancement fails. How can I avoid this?

• Difference between SRC and HREF

  - by Vijey

  The SRC and HREF attributes are used to include some external entities like an image, a CSS file, a html file, any other web page or a javascript file. Is there a clear differentiation between SRC and HREF? where/when to use SRC or HREF? I think they can't be used interchangeably. I'm giving below few examples where these attributes are used: To refer a CSS file: href="cssfile.css" inside the link tag To refer a js file: src="myscript.js" inside the script tag To refer an image file: src="mypic.jpg" inside an image tag To refer another webpage: href="http://www.webpage.com" inside an anchor tag
