Wt

Hello

I've tried the dbo examples from http://www.webtoolkit.eu/wt/doc/tutorial/dbo/tutorial.html. All works fine.

Now when I change the classname of the class 'User' to 'CSystemError', something mystery will happen:

The const_iterator of the Wt::Dbo::collection can't resolve the class members...

Here are my classes:

class CSystemError {
public:
  enum Role {
    Visitor = 0,
    Admin = 1,
    Alien = 42
  };

  int test;
  std::string name;
  std::string password;
  Role        role;
  int         karma;

  template<class Action>
  void persist(Action& a)
  {
    Wt::Dbo::field(a, test,     "test");
    Wt::Dbo::field(a, name,     "name");
    Wt::Dbo::field(a, password, "password");
    Wt::Dbo::field(a, role,     "role");
    Wt::Dbo::field(a, karma,    "karma");
  }
};


class User {
public:
  enum Role {
    Visitor = 0,
    Admin = 1,
    Alien = 42
  };

  int test;
  std::string name;
  std::string password;
  Role        role;
  int         karma;

  template<class Action>
  void persist(Action& a)
  {
    Wt::Dbo::field(a, test,     "test");
    Wt::Dbo::field(a, name,     "name");
    Wt::Dbo::field(a, password, "password");
    Wt::Dbo::field(a, role,     "role");
    Wt::Dbo::field(a, karma,    "karma");
  }

};

In the 'find' part with the iteration:

  {
    Wt::Dbo::Transaction transaction(session);
    typedef Wt::Dbo::collection< Wt::Dbo::ptr<CSystemError> > Users;
    Users users = session.find<CSystemError>();
    std::cerr << "We have " << (int)users.size() << " users:" << std::endl;

        for (Users::const_iterator i = users.begin(); i != users.end(); ++i)
      std::cerr << " user " << (*i)->name                                  // 'name' will not be proposed... 
        << " with karma of " << (*i)->karma << std::endl;              // 'karma' will not be proposed...
  }

  {
    Wt::Dbo::Transaction transaction(session);
    typedef Wt::Dbo::collection< Wt::Dbo::ptr<User> > Users;
    Users users = session.find<User>();
    std::cerr << "We have " << (int)users.size() << " users:" << std::endl;

        for (Users::const_iterator i = users.begin(); i != users.end(); ++i)
      std::cerr << " user " << (*i)->name                                 // 'name' will be proposed... 
        << " with karma of " << (*i)->karma << std::endl;             // 'karma' will be proposed...
  }

Are there other classnames that I shouldn't use?
