BTW there is a blog application in svn http://cppcms.svn.sourceforge.net/viewvc/cppcms/blog/trunk/

This once runs CppCMS blog.

Honestly whatever feels right.

You may create some set of "model" classes over cppdb and then set
the values to the form from this model.

You may use temporary variables.

You can call.

   cppdb::result r = ...

   my_from.name.value(r.get<std::string>(0));
   my_from.title.value(r.get<std::string>(1));


And so on.

Its really up to you.

Some users create some set of model classes and separate them from controller
some use directly SQL in controller and setup their content.

Whatever feels right
