[Cartoweb-users] Setting the query policy via parameter

[Marc.Monnerat at swisstopo.ch]

Hello Oliver,

Thank you for your explanation. Looks pretty logical. Well, I think the
"query" plugin was originally build for graphical selection build. The
"query_select" is  more or less a wild addition and should be removed.

My problem was to to select objects, both graphically (queryByShape) and by
attributes (queryByAttributes) and to be able to filter in/out objects by
both methods. That means, I have to extend the "query" plugin for attributes
querying, but it's a daring enterprise to me. Is there any plan in that
direction from your side ? Or is there any solutions I did not thought of?

Regards,

Marc

Hi Marc

after investigating a bit, I could only find that unless a geometry is 
received, the tables are not intersected. So the problem is not directly 
linked to the policy but how the query is handled on server side when using 
GET parameters.
Im not yet sure why a geometry is needed at that stage, that plugin being 
fairly complicated.
So until one of my colleague more knowledgable with plugin become available,

I can only open a bug report about that issue, sorry.

regards
Oliver
