[odb-users] Nested Vectors of Composite Values

Hello everybody,
I'm trying to use the following setup of classes (stripped down to a simple
example). classes.h:
#pragma db value
class A {
std::string first;
std::string second;
friend class odb::access;
};
#pragma db value
class B {
std::string hello;
std::vector<A> a;
friend class odb::access;
};
#pragma db object
class C {
#pragma db id
std::string name;
std::vector<B> b;
friend class odb::access;
};
And I run the following to command, just to generate the SQL database schema:
# odb --database sqlite --generate-schema-only --schema-format sql classes.h
I would have expected, that three tables were generated in classes.sql:
- C
- C_b
- C_b_a
But actually, I get only these two:
CREATE TABLE "C" (
"name" TEXT NOT NULL PRIMARY KEY);
CREATE TABLE "C_b" (
"object_id" TEXT NOT NULL,
"index" INTEGER NOT NULL,
"value_hello" TEXT NOT NULL,
CONSTRAINT "object_id_fk"
FOREIGN KEY ("object_id")
REFERENCES "C" ("name")
ON DELETE CASCADE);
What am I doing wrong? What am I missing?
Any ideas?
Thanks,
Henning
