DuplicatelessORMLite

Duplicateless creation of new records for ORM Lite

Description

By default ORMLite doesn't supports create-if-not-exists logic. Of course BaseDaoImpl class has createIfNotExists and createOrUpdate methods, but they both just make checks on id fields. That is if passed DTO has default id value (0 or null) new record will be created.

This tiny library extends BaseDaoImpl and adds insertIfNotExists method, which creates records in database only if they aren't present yet. Basically it performs check of all values except id.

Instalation

Add this dependency to the build.gradle:

compile 'com.github.mikeherasimov:duplicatelessormlite:0.1'

Configuration steps

• set DuplicatelessDaoImpl.class as daoClass for your DTOs, for example:

@DatabaseTable(tableName = Food.TABLE_NAME, daoClass = DuplicatelessDaoImpl.class)
public class Food {
...
}

• don't use primitive types for fields, except id field (it can cause exception, however I'm not sure)

Also there is properly configured example in sample directory, so you may want to check it.
