I know that I’d already post a message about deferred but I think I haven’t understand very well.

I have a function that is suppose to return a new dictionnary but it returns a deferred.

class MainPage(pages.BasePage):

templateFile = "main.html"

def initialize(self, dbpool=None):

self.dbpool = dbpool

def setUp(self, request, *args):

var = self.initPermissions(request) #var is suppose to get the new list

print var

def wmfactory_welcome(self, request):

return "Bienvenue, %s" % request.getComponent(myguard.Authenticated).name

def initPermissions(self, request): #create and return the results of a sql query

group = request.getComponent(myguard.Authenticated).group

listGroup = group.split(',')

sql = "select permission from permissions where 1"

for item in listGroup:

sql += " or permissions.group='%s'" % item.lstrip()

theDeferred = self.dbpool.runQueryDict(sql)

return theDeferred.addCallback(self.makeDict) # suppose to call makeDict when the results has arrived

def makeDict(self, results):

# when I print what is in results, I can see all the data from the sql query

listPermissions = []

for item in results:

listPermissions.append(item.get('permission'))

return listPermissions # return the new list but the function setUp receive a deferred

I’ve put some comments in the code to help you understand what I want.

The big problem is that var receive a deferred and not the new list
