entities

问题 I have a Entity of TeamMembers. And the TeamMember can have a Specification with a value. So I have three Entities: TeamMember, Specifications, SpecificationValues. In the SpecificationValue table I want to store the TeamMember_id, the Specification_id and the value that is just for that TeamMember. The Specifications and TeamMembers Entities are working. But now I want to show all the Specifications, if I go to the edit route (see code example) of a TeamMember, and have to possibility over

问题 I have a table Object that has 2 fields that are foreign keys (user_id and teacher_id).

So supposing I know the user_id and teacher_id for my object, instead of doing: $object->setUserId(1) I have to do: $user = $this->getDoctrine()->getRepository('MyBundle:Users')->find(2); $object->setUser($user) is there no way to work

问题 We are starting with a MVC project using EF. We will need write a lot of queries in LINQ using subselect and don't have figured out yet how this could be done. The most simple case of these is in this form: select p.Id, p.Title, (select count(*) from Comments c where c.PostId = p.Id ) as CommentCount from Post p where p.UserId = 'John'; Reading the "101 page" of examples from Microsoft and Stack Overflow I couldn't find a example like this. I found examples using join and group, but in some

问题 i tried to share my entities in a JPA 2.0 project in eclipse Juno, ´cause i´m creating a test project and i need to access then there to make my tests and if i create any other project a can reuse those entities. The biggest problem is that hibernate ( 4.1.9 ) can find my jar in a relative path, but the most strange is that in my test project using only Spring 3 hibernate read my entities jar and hbm files perfectly. But when i try to do the same with the real project using tomcat 7.0.27 it

问题 I think that the standard practice to name tables in MySQL is to use plural names. The classes refering to those tables should also be plural? For example, imagine that you have a table called Users, that is used for authentication purposes.

What are JPA enities? does they actually hold the data for each row, I mean, are they stored instances that hold the row data? or they just map tables of the db and then insert and delete in them? for example if I use this: entity.setUserName("michel");
