copied!<p>I'm posting my solution (update user details, not overwrite them) so it may help someone. Based on <code>pipeline.user.update_user_details</code> I coded the following:</p> <pre><code>def fill_user_details(backend, details, response, user, is_new=False, *args, **kwargs): """Fills user details using data from provider, without overwriting existing values. backend: Current social authentication backend details: User details given by authentication provider response: ? user: User ID given by authentication provider is_new: flag source: social_auth.backends.pipeline.user.update_user_details """ # Each pipeline entry must return a dict or None, any value in the dict # will be used in the kwargs argument for the next pipeline entry. # # If any function returns something else beside a dict or None, the # workflow will be cut and the value returned immediately, this is useful # to return HttpReponse instances like HttpResponseRedirect. changed = False # flag to track changes for name, value in details.iteritems(): # do not update username, it was already generated if name in (USERNAME, 'id', 'pk'): continue # set it only if the existing value is not set or is an empty string existing_value = getattr(user, name, None) if value is not None and (existing_value is None or not is_valid_string(existing_value)): setattr(user, name, value) changed = True # Fire a pre-update signal sending current backend instance, # user instance (created or retrieved from database), service # response and processed details. # # Also fire socialauth_registered signal for newly registered # users. # # Signal handlers must return True or False to signal instance # changes. Send method returns a list of tuples with receiver # and it's response. signal_response = lambda (receiver, response): response signal_kwargs = {'sender': backend.__class__, 'user': user, 'response': response, 'details': details} changed |= any(filter(signal_response, pre_update.send(**signal_kwargs))) # Fire socialauth_registered signal on new user registration if is_new: changed |= any(filter(signal_response, socialauth_registered.send(**signal_kwargs))) if changed: user.save() </code></pre>
