ORMlite Android foreign key support

寵の児 提交于 2019-11-30 08:20:34
I am not clever from ORMlite documentation. Is is possible to declare in class, that this parameter is foreign key? e.g. I have table Customer: @DatabaseTable(tableName = "customer") public class Customer { @DatabaseField(id = true) private String customerName; @DatabaseField private String customerSurname; @DatabaseField(foreign = true) private String accountNameHolder; @DatabaseField private int age; public Customer() { } } AccountNameHolder should aim towards DatabaseField name from table Accounts. How to do that? I have found only parameter foreign = true, but there is nothing about, which

问题 Have a problem with querying data via Ormlite DAO, when there are few thousand results. Code: List<Point> pl = db.getPointsDAO().queryBuilder().where(). eq("route_id", croute).query(); When I want to get a large list of points List<Point> pl for current Route croute I have to wait like 40 sec for 40.000 points. where Point.class is: @DatabaseTable(tableName = "points") public class Point extends BaseEntity { @DatabaseField(generatedId = true) private Integer point_id; @DatabaseField(canBeNull

Ormlite setup without using base activities

岁酱吖の 提交于 2019-11-30 07:04:21
I'm using ORMLite in an android project, and I'm not wanting to use the extended activities because I'm inserting values into the database on an AsyncTask. In the docs it says: "If you do not want to extend the OrmLiteBaseActivity and other base classes then you will need to duplicate their functionality. You will need to call OpenHelperManager.getHelper(Context context, Class openHelperClass) at the start of your code, save the helper and use it as much as you want, and then call OpenHelperManager.release() when you are done with it." It also says to add the database helper class in the

ORMLite and Images saved as BLOB on Android

我的未来我决定 提交于 2019-11-30 05:07:58
So I recently switched my database stuff over to ORMLite in my android tablet application I am writing. So far so good, got most things refactored/recoded. Though I am having issues to what was originally stored in the database as a BLOB. In my original data model it looked like this: byte[] imageBytes; but I don't think I can use that in ORMLite, best I could tell it has to be a string so now I have: @DatabaseField String picture; But now, I am confused as to how to read and write those data bits as bytes, etc...I was using code like this to ferry data to and from the database: ... //Set the

How do I properly annotate inheritance classes using ORMLite?

大城市里の小女人 提交于 2019-11-30 05:04:54
问题 I'm trying to use inheritance with ORMLite and I can't work out if it is supported or not from looking at the documentation and googling. What I want to do is have public abstract class Person{ public int id; public String name; } public class Student extends Person{ public String school; public String year; // other student stuff } public class Teacher extends Person{ public String title; // other teacher stuff } What I can't work out (assuming it's supported) is how to annotate the 3

What is the best way to implement many-to-many relationships using ORMLite?

£可爱£侵袭症+ 提交于 2019-11-30 04:48:07
I'm currently playing with ORMlite to make a model with tables and relationships. One relationship is a many-to-many relationship. What's the best way to implement that? To be more concrete: Let's say I've got these two tables Product id brand Purchase id A purchase can have several products and one products can be in several purchases. Using ORMLite I could have a @ForeignCollectionField in each model but I don't think it would work. The only valid solution I see is to make a third table Product_Purchase to link Product and Purchase with many-to-one relationships. What do you folks think?

Setup Gradle to run Java executable in Android Studio

隐身守侯 提交于 2019-11-30 02:39:24
问题 So here's the deal: I'm using ORMLite for Android, which uses annotations for it's mapping in Android. As you know, annotations are slow in Android, and the makers of ORMLite have realized this, so they added the ability to run a java executable to generate a resource file that bypasses the need to check annotations at runtime in the android app. It looks something like this: public class DatabaseConfigUtil extends OrmLiteConfigUtil { private static final Class<?>[] classes = new Class[] {

Is there any way to disable ORMLite's check that a field declared with DataType.SERIALIZABLE implements Serializable?

房东的猫 提交于 2019-11-30 00:00:48
问题 Question title just about says it all. I have a field declared like this: @DatabaseField(canBeNull=false,dataType=DataType.SERIALIZABLE) List<ScheduleTriggerPredicate> predicates = Collections.emptyList(); Depending on context, predicates can either contain the empty list or an immutable list returned by Collections.unmodifiableList(List) with an ArrayList as its parameter. I therefore know that the object in question is serializable, but there is no way I can tell the compiler (and therefore
