  ProgrammingError: ERREUR:  la référence à la colonne « parent_id » est ambigu
  LIGNE 1 : ... id, count(project_project.id) AS parent_id_count,parent_id,...

  I think there is an error while constructing the query while grouping
  by parent: the colun 'parent_id' may be related to more than one table

  Grouping by "Partner" and/or by "Manager" is okay.
