    <p>I'm trying to serialize using boost property tree write_json, it saves everything as strings, it's not that data are wrong, but I need to cast them explicitly every time and I want to use them somewhere else. (like in python or other C++ json (non boost) library)</p> <p>here is some sample code and what I get depending on locale:</p> <pre><code>boost::property_tree::ptree root, arr, elem1, elem2; elem1.put&lt;int&gt;("key0", 0); elem1.put&lt;bool&gt;("key1", true); elem2.put&lt;float&gt;("key2", 2.2f); elem2.put&lt;double&gt;("key3", 3.3); arr.push_back( std::make_pair("", elem1) ); arr.push_back( std::make_pair("", elem2) ); root.put_child("path1.path2", arr); std::stringstream ss; write_json(ss, root); std::string my_string_to_send_somewhare_else = ss.str(); </code></pre> <p>and <code>my_string_to_send_somewhere_else</code> is sth. like this:</p> <pre><code>{ "path1" : { "path2" : [ { "key0" : "0", "key1" : "true" }, { "key2" : "2.2", "key3" : "3.3" } ] } } </code></pre> <p>Is there anyway to save them as the values, like: <code>"key1" : true</code> or <code>"key2" : 2.2</code>?</p>

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.
