+        As fields in MongoEngine may use different names in the database (set
+        using the :attr:`name` keyword argument to a :class:`Field` 
+        constructor), a mechanism exists for replacing MongoEngine field names
+        with the database field names in Javascript code. When accessing a 
+        field, use square-bracket notation, and prefix the MongoEngine field
+        name with a tilde (~).
