Bug report #12060
WFS: missing fields when using GetFeature on a layer with a join
|Affected QGIS version:||master||Regression?:||No|
|Operating System:||Easy fix?:||No|
|Pull Request or Patch supplied:||No||Resolution:||fixed/implemented|
|Crashes QGIS or corrupts data:||No||Copied to github as #:||20262|
- shapefile layer with main data
- MySQL table (view)
- linked, caching enabled.
All works well so far.
But when I do a WFS-request, I only see the shapefile's attribute fields - not the ones I joined.
I checked permissions, and even tried checking select/insert/update/delete for just the table too.
I also checked the "Fields" tab of the shapefile - I see the fields listed, with WFS checked.

Just to be sure, are we speaking about QGIS server here, right?
So the issue would be: if you do a join in a layer, then the same layer published (with qgis server) as WFS do not show the joined attributes, right? And also you are saying that the same layer with a join do not work at all if using QGIS as wfs client, right?
Does this happen with any type of layers and joined tables, or just specific formats?

- Affected QGIS version changed from 2.6.0 to master
Using QGIS as WFS client works for me for WFS layers with joined tables from QGIS server.
Anyway I confirm that the joined attributes show always empty.
This is on QGIS (server) master, not sure if it worked in previous qgis server releases, anyone that can check?

We are indeed talking about QGis Server.
The MySQL is on another server. If I set up the service using QGis Desktop (that's where I also perform the "join", so I'm not reading the view directly from MySQL, the join is performed by QGis), the view works fine when I view it in the application.
I check the permissions, it seems fine for:
- the layer I joined to (shapefile)
- the individual fields listed (view created by QGis)
- I even added permissions in the WFS-matrix for the table (MySQL table)
But when I then open the WFS-service using QGis, the attributes do not show up. I don't know how this worked in previous versions.

I don't know how this worked in previous versions.
this is the point, I already confirmed that joined attributes do not show in qgis server wfs layers regardless of the data type used. Now it is just a matter to confirm if it ever used to work in old releases.

Perhaps it is because of issues when one would insert, update, delete a field which has been joined to the layer?
If that's the case, the WMS/WFS fields should be disabled in the [Fields] tab.
Although I feel it should still allow you to do a select though.
On the other hand: I'm greateful for this, but QGis does allow a WFS Service to access all the properties of features which originate from a MySQL View in the database itself (relying on this now!)
