Question

In a normal application i set services

services = {
    'users.login': login,
    'test': router
}

but I would like to do like this:

services = [
    'users.login',
    'test'
]

and every request goes to router function. this takes 2 params: service name (can be “users.login” or “test” in this case) and input (that is the object sent by flex to python)
then if the command(service) from flex is named “users.login”. I would like to run the router with the params and then this will open the function login in the commands.users.login package. How would I do that? Thanks.

Solved last night!

from pyamf.remoting.gateway.google import WebAppGateway
import logging

class TottysGateway(WebAppGateway):
def __init__(self, services_available, root_path, not_found_service, logger, debug):
    # override the contructor and then call the super
    self.services_available = services_available
    self.root_path = root_path
    self.not_found_service = not_found_service
    WebAppGateway.__init__(self, {}, logger=logging, debug=True)

def getServiceRequest(self, request, target):
    # override the original getServiceRequest method
    try:
        # try looking for the service in the services list
        return WebAppGateway.getServiceRequest(self, request, target)
    except:
        pass

    try:
        # don't know what it does but is an error for now
        service_func = self.router(target)
    except:
        if(target in self.services_available):
            # only if is an available service import it's module
            # so it doesn't access services that should be hidden
            try:
                module_path = self.root_path + '.' + target
                paths = target.rsplit('.')
                func_name = paths[len(paths) - 1]
                import_as = '_'.join(paths) + '_' + func_name
                import_string = "from "+module_path+" import "+func_name+' as service_func'
                exec import_string
            except:
                service_func = False

    if(not service_func):
        # if is not found load the default not found service
        module_path = self.rootPath + '.' + self.not_found_service
        import_string = "from "+module_path+" import "+func_name+' as service_func'

    # add the service loaded above
    assign_string = "self.addService(service_func, target)"
    exec assign_string

    return WebAppGateway.getServiceRequest(self, request, target)
