[odb-users] How to use the lazy_weak_ptr?

[黄奕]

I currently have two odb model like below:
A.hpp
class A
{
...
private:

odb::lazy_shared_ptr<B> m_b;
...

};
#pragma db object(A) pointer(std::shared_ptr)
#pragma db member(m_b)


B.hpp
class B
{
...
private:
odb::lazy_shared_ptr<A> m_a;
...
};
#pragma db object(B) pointer(std::shared_ptr)
#pragma db member(m_a)


They obviously have circular reference, and I want to use lazy_weak_ptr to fix it by the codes below:
A.hpp
class A
{
...
private:
odb::lazy_shared_ptr<B> m_b;
...
};
#pragma db object(A) pointer(std::shared_ptr)
#pragma db member(m_b)


B.hpp
class B
{
...
private:
#pragma db inverse(m_b)

odb::lazy_weak_ptr<A> m_a;
...
};
#pragma db object(B) pointer(std::shared_ptr)
#pragma db member(m_a)
 
But I get the error of “error: object data member ‘ m_a' specified in db pragma column is inverse”.


It seems like I use the lazy_weak_ptr in a wrong way, is there anyone can help me?
