QGIS Server GetFeatureInfo request should take attribute sort order into account

[cxcandid]

Feature description

QGIS Server 3.24.2-1 (Windows): GetFeatureInfo request takes over the column aliases but not the configured attribute sort order.

Additional context

No response

[elpaso]

I'm not sure I understand, can you please add some details?

[cxcandid]

In QGIS we can configure an expression for attribute table sorting, but this sort order is not recognized by QGIS Server in a GetFeatureInfo request.

Or maybe you could implement another GetFeatureInfo paramter for sorting by attribute?

@cxcandid Maybe this is interresting for you #41031

I honestly don't understand your request: how the sort order for attribute table should affect the GetFeatureInfo response. All the best

[tudorbarascu]

@gioman I think this should have the feedback label or be closed.

@tudorbarascu my feature request concerns the sorting of the features in a GetFeatureInfo request and not the sorting/reordering of the attributes/fields.

Maybe the attribute place is not the right place to configure the sort order for features in GetFeatureInfo response but AFAIK there is no way to configure it in QGIS or via a parameter in the request.

It seems GetFeatureInfo request is missing a SORTBY parameter as WFS GetFeature has.

Anyone can confirm?

@nboisteault The attribute table column configuration affects the visibility and order of the attributes, so why not use the sort order of the table as the default sort order for the GetFeatureInfo query?

I can confirm, there is no way to order the results. I would add that there is not a simple way we can add this functionality: the request can query multiple layers and we should specify the ordering criteria for all of them independently.

WFS and OAPIF on the contrary can filter and order results, because they operate on a single layer for each request.

Perhaps we could add a sort by option for each layer in the server configuration panel, I am not convinced that the attribute table is the right place for this configuration: the attribute table is oriented to the desktop data visualization.

We can use w/ WFS GetFeature, several TYPENAME and several FILTERs for example: https://docs.qgis.org/3.28/fr/docs/server_manual/services/wfs.html#filter

For a GetFeatureInfo request, would it be possible to have several LAYERS and several SORTBY separated by commas ?
