Hi,all:

   I'm trying to avoid project name repeated while creating a project by using this code:

@api.constrains('name')
def check_info(self):
    info_id = self.search([('name', '=', self.name)])
    if len(info_id) > 1:
        raise Warning('%s project name repeated!' % info_id)
  It will warn me when I try to create a project when there is another project
with same as I created.


  However,if a project named "Project_A"and its privacy is "followers" and I'm not invited,I 
can still create a project named "Project_A" without receiving a warning,in fact I wanna avoid 
creating this "Project_A" again.
  So how can I update my code or do some configuration to meet the requirements?Thanks for your 
answer

Search duplicates under the SuperUser (sudo):

@api.constrains('name')
def check_info(self):
    info_id = self.sudo().search([('name', '=', self.name)])
    if len(info_id) > 1:
        raise Warning('%s project name repeated!' % info_id)
