How do I implement one-many relationship in ORMLite Android?
please find the example
public class A {
private String name;
@DatabaseField (foreign = true, foreignAutoRefresh = true, columnName = "A")
private B b;
@DatabaseField(columnName = "author")
private String authorName;
}
public class B {
@DatabaseField(generatedId = true, columnName = "id")
private long id;
@DatabaseField(columnName = "name")
private String name;
@ForeignCollectionField
Collection<A> aees;
}
B has collection of A. I am calling dao.create(b);
Now i create dao of b, since b has all the data. But the table B has only created with data, A is never created. Kindly could some one help?

Right. You need to create the A
items using:
for (A a : b.aees) {
aDao.create(a);
}
ORMLite does not automatically create those for you.
You might take a look a the source code of the foreign-collection example program.
