%Docstring(signature="appended")
The :py:class:`QgsFieldMappingModel` holds mapping information for
mapping from one set of :py:class:`QgsFields` to another, for each set
of "destination" fields an expression defines how to obtain the values
of the "destination" fields. The model can be optionally set "editable"
allowing to modify all the fields, by default only the mapping
expression is editable.

%Docstring
Constructs a QgsFieldMappingModel from a set of ``sourceFields`` and
``destinationFields``, initial values for the expressions can be
optionally specified through ``expressions`` which is a map from the
original field name to the corresponding expression. A ``parent`` object
can be also specified.

Sets the destination fields editable state to ``editable``

Sets a map of destination field name to :py:class:`QgsProperty`
definition for field value.

Appends a new ``field`` to the model, with an optional ``expression``

Removes the field at ``index`` from the model, returns ``True`` on
success

Moves down the field at ``index``
%End

Moves up the field at ``index``
%End

Set source fields to ``sourceFields``

Returns the context generator with the source fields

Sets the base expression context ``generator``, which will generate the
expression contexts for expression based widgets used by the model.

Set destination fields to ``destinationFields``, initial values for the
