Modifying cfg in script

[Max Demars]

Hi!

I am a new user of TileStache. I was using mapnik python binding in my geodjango application before and now I would like to use the capabilities of TileStache. After installing TileStache and running the demo, I would like to bind the library in my application.

I want to use PostGeoJSON.Provider to create tiles from queries on a postgis table. As the queries and rendering options would be determined by the app's user, how to modify the tileStache.cfg from a python script to pass all the  variable?


What would be the best way to achieve that?

Thank you for your help,

Max Demars

Hi Max,

It sounds like you want to create a dynamic configuration, is that right? One that is different for different users depending on some external factors?

The TileStache configuration object must conform to this description:
http://tilestache.org/doc/#custom-configuration

But you have quite a bit of leeway to create a custom behavior within that. For example, we have a dynamic configuration client in the goodies package that may be a model for you:

Thank you for your answer Mike.

I wonder now if its possible to use mapnik.Map python object instead of mapnik.xml with TileStache mapnik provider?
