[OSM-dev] amf_controller

RIchard

Over the weekend I variously looked at amf_controller in an attempt to  
move it to using all the rails objects.

The number one problem is that we have multipart keys in our database  
and rails doesn't natively support that. That is, they key on the way  
nodes table is id, sequence_id. Not just id. So, all the SQL you're  
writing with joins, rails will magically do for you normally with  
something like

Way.find(42, :include => :nodes)

But it fails because of the multipart keys.

There's a magic plugin that makes all of this go away but I need to  
test it more to make sure it doesn't fuck up other bits of code. I'm  
not online right now but it'll be in http://del.icio.us/SteveC/rails 
+key or some such.

Second, what would be really nice is a description of the functions,  
above each function (rdoc for bonus points) which lists what the input  
is (with object types) and what the expected output is. I think this  
will be a lot easier to do code against than reverse-engineering the  
SQL and so on. I've looked at the wiki but the function descriptions  
aren't complete enough (unless I've missed something) as above.

have fun,
