Description

Hi,

I've been trying to run the Shortest Path algo from the "Kanagawa" sample on my own server, but the result is as follows:

Warning: Error?: msDrawMap(): Failed to draw layer named 'path'. in /usr/local/apache2/htdocs/routingj/phtmls/sp.backup.phtml on line 77

Fatal error: Call to a member function saveWebImage() on a non-object in /usr/local/apache2/htdocs/routingj/phtmls/sp.backup.phtml on line 78

Does anyone ever run into this problem? Anything anyone can offer to help?

Thanks, ned

  • owner changed from somebody to anton.
  • priority changed from major to minor.
  • status changed from new to assigned.

Please try to execute:

SELECT * from shortest_path_astar_as_geometry_internal_id('kanagawa', 76309, 124369);

instead of

SELECT * from shortest_path_astar_as_geometry_internal_id('SELECT id,the_geom FROM kanagawa', 76309, 124369);

Same result when I just used 'kanagawa'.

I've managed to make it work temporarily by changing the code in shortest_path_astar2_as_geometry_internal_id_directed.

In the original code:

query := query 'FROM '

quote_ident(geom_table) ' where setSRID('BOX3D('ll_x' '

ll_y','ur_x' 'ur_y')'::BOX3D, ' srid

') && the_geom, ' quote_literal(sourceid) ' , '

quote_literal(targetid) ' , dir, rc ),'

quote_ident(geom_table) ' where edge_id = gid ';

My temporary solution:

query := query 'FROM '

quote_ident(geom_table) ' where setSRID('BOX3D('ll_x' '

ll_y','ur_x' 'ur_y')'::BOX3D, ' srid

') && the_geom, ' quote_literal(sourceid) ' , '

quote_literal(targetid) ' , false, false ),'

quote_ident(geom_table) ' where edge_id = gid ';

Difference is in the syntax for "dir" and "rc". I forced it to use "false" and it works (i'm sure "true" would also work). I am a newbie in postgis. I am not sure how the quote and double pipe system works but I suspect that the original code is only missing a couple of single quote in the original code.

any ideas?

Thanks

  • status changed from assigned to closed.
  • resolution set to fixed.

OK, it seams like it started with PostgreSQL 8.2.5

Since this version it is not allowed to concatenate boolean and text.

Fixed with #47

Sorry, I can't find ticket #47. Did you happen to mis-type it?

Thanks, I really appreciate all your help.

Yeah, sorry. I meant [47].
