.. _layer_fields:

Layer fields translations & filters
-----------------------------------

It is possible to rename a field or choose not to show the field with it's value.

For example see the pictures below for renaming the field GRAY_INDEX:

.. image:: ../../images/wms_original_props.jpg

Into this:

.. image:: ../../images/wms_translated_props.jpg

Filter fields
-------------
To prevent certain fields from showing in the information panel, set a layer's filter_fields property:
  

    **Example request:**

    .. http:patch:: /maps_api/v2/server/viewers/(string:identifier)/layers/(int:layer)

    .. sourcecode:: http

        {
            "filter_fields": [
                {
                    "name": "fid",
                    "visible": false
                },
                {
                    "name": "objectid",
                    "visible": false
                },
                {
                    "name": "vhn_new",
                    "visible": false
                }
            ]
        }

Translations
------------
To give a field a more meaningful name, set a layer's translations property:

    **Example request:**

    .. http:patch:: /maps_api/v2/server/viewers/(string:identifier)/layers/(int:layer)

    .. sourcecode:: http

        {
            "translations": [
                {
                    "name": "naam_n2k",
                    "translation": "Naam"
                },
                {
                    "name": "shape_leng",
                    "translation": "Lengte"
                },
                {
                    "name": "shape_area",
                    "translation": "Oppervlakte"
                },
            ]
        }
