First, you are overwriting, not adding to, 'string' on each iteration of the
loop. Second self.demandeur is a ManyRelatedManager which you cannot
iterate through. If you want to iterate through the items in the set you
have to call .all() on the ManyRelatedManager. Something like (untested)
should do it:
def dem(self):
return ' '.join([str(agent) for agent in self.demandeur.all()])
