Body
The answer was actually quite simple: make the container behave like an stl container, and then to use boost's <code>iterator<>()</code> function instead of <code>range()</code>. To do this, I had to make the typedefs in <code>stl_iter</code> public, and to rename them to <code>value_type</code> and <code>iterator</code>. Heres the updated C++ code. <pre><code>#include <memory> #include <vector> #include <string> #include <boost/python.hpp> template<class T> T* get_pointer(std::shared_ptr<T> const& p) { return p.get(); } template<class T> class stl_iter { protected: virtual T& get_vector()=0; public: // Next two lines changed, and made public typedef typename T::value_type value_type; typedef typename T::iterator iterator; virtual ~stl_iter() {} virtual void append(value_type item) { get_vector().push_back(item); } virtual iterator begin() { return get_vector().begin(); } virtual iterator end() { return get_vector().end(); } }; class K { std::string val; public: K(std::string s) : val(s) {} std::string get_val() const { return val; } }; typedef std::shared_ptr<K> pK; typedef std::vector<pK> vK; class Container : public stl_iter<vK> { vK items; protected: vK& get_vector() { return items; } public: virtual ~Container() {} }; typedef std::shared_ptr<Container> pContainer; typedef std::vector<pContainer> vContainer; BOOST_PYTHON_MODULE_INIT(test) { using namespace boost::python; class_<K, pK>("K", init<std::string>()) .def("__str__", &K::get_val) ; class_<Container, pContainer>("Container") .def("append", &Container::append) // Use iterator() instead of range() .def("__iter__", iterator<Container>()) ; } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
