Hi,
I'm trying to update a record using modify() for table with altered primary
key, But the commit fails and exit with error: "constraint failed". When I
checked the query generated I noticed that the primary key is in the fields
list.
The following code demonstrate the problem:
//Definitions
typedef long long DbId;
namespace Wt {
namespace Dbo {
template<>
struct dbo_traits<Client> : public dbo_default_traits {
static DbId invalidId() { return UUID::generate(); }
static const char *surrogateIdField() { return 0; }
};
}
class Client {
public:
DbId id;
template<class Action>
void persist(Action& a)
{
dbo::id(a, id, "id");
}
};
// This is how I search for record to be modified:
clientPtr = session()->find<Client>().where("name = ?").bind("name");
// Every thing is ok until now, I can obtain the data and there is a result
of this query
//The error pops when I call the following:
clientPtr.modify()->note = "note";
Thanks alot,
