Feature request #16040

Updated by Regis Haubourg over 2 years ago

Relation reference widget does not allow to spatially filter potential related features. (that widget [[https://issues.qgis.org/attachments/9427/emeded_form_relationreferenz.jpg]] )



Filtering by expression instead of simple fields would allow to call functions such as

<pre>

intersects( $geometry , geomFromWKT( $current_canvas_extent ))

</pre>



That would allow a dropdown list reduced to a few neighbouring features. Currently it loads the whole layer, and can kill QGIS.



a native checkbox to filter by canvas would be also good for average users
