Forum OpenACS Development: New package: MAPS (Google Maps integration)

Do you have a public demo?

Sorry, Eduardo. I think of the server is down.

I`m glad you like it. Sorry about these lines; I`m going to remve these from the code.

Actually it`s very simple to write a callback. It`s based on the object_type you want to map. Take a look at the file /tcl/maps-callback-procs.tcl and see the implementations for organization and dotlrn_community. The callback must supply the following fields:

-object_id: The Id of maped object
-url: The URL to access this object (maybe somebody could use the service contract API to get it)
-pname: Object name
-message: Localized message to access this object, meaning something like "Access this object"

These parameter must be upvar'd in an array named map_info.

To insert a maped object, access the link maps_instance/admin and see the options.

Post here if you have any doubts

We have a provisory documentation at the address http://www.softwarepublico.gov.br/dotlrn/clubs/openacs/xowiki/en/pacote-maps.

Feel free to post here if you have any doubts.

Sorry. We have a lack of documentation that should be solved soon.

The map information is really a tricky thing, but it's not hard to understand. The map is based in two objects: maps and position. Avery time you create a package instance, a new map is created, and this map can have as many positions as you want.

The package is designed to think that you are going to mount the map somewhere and include it in another place. Let's say that you you mount it under /maps: a new map_id will be created for this instance. You are going to include this map_id in any other you want to.

So, what you have to do is:

1 - Create the callback for your object_type. It's pretty simple: it should only supply some info that is specific for this object and we use it when we are maping. I guess this part of documentation is OK.

2 - Include the page /maps/lib/position-view with the maping object_id, return_url and map_id (we have to find a better way to discover this map_id) in the page that you edit the object information. In organizations package, for example, the information page should be organizations/www/one and object_id should be organization_id. This page will show the object's individual position.

3 - Include the page /maps/lib/map-view supplying the map_id (again, there must be a clever way to do it) and you can see all the positions in this map.

I recommend you to run a svn export right now, because we have done a lot of improvements in the last few hours. Let me know if there's any other thing you want to know, so we can put it back in the documentation.

I hope it's useful. :)

Well, if you could supply more info about the error maybe I could help you more. My guess in this case is that you didn't sign out for a Google Maps API Key, as the map is not being shown. Take a look at the docs here:

http://www.softwarepublico.gov.br/dotlrn/clubs/openacs/xowiki/en/pacote-maps

Or just type /doc in your install and click under the maps package. You have to go to /maps/admin/ page and click on the edit parameters link. In this page you have to supply the key that Google gives you here: http://code.google.com/apis/maps/signup.html

If it doesn't work, try to give me more details about the error, such as log messages or something like this, so I can help you better.

I hope it helps.

Sorry, my mistake. You could try the SVN at trunk without password:

# svn co http://svn.softwarepublico.gov.br/svn/openacs/trunk/packages/maps
