when use morph_to relation, can't use where_has to filter

[nervermore]

I have to model, AdminAuth ， Services and Works
The relations are below:

• AdminAuth
  id
  source_type
  source_id

• Services
  id

• Works
  id

the source_type has two:
"company"--Services ,
"work"---Works

class AdminAuth(Model):
    __table__ = 't1_admin_auth'
    __casts__ = {
        'latest_check_time': 'str',
    }

    # relations
    @morph_to
    def source(self):
        return

class Services(Model):
    __table__ = 'service'
    __morph_name__ = 'company'

    @scope
    def active(self, query):
        return query.where('active', 1).where('state', 1).where('isPay', 1)

    @morph_one('t1_admin_auth')
    def adminAuth(self):
        return AdminAuth

now , if i use

AdminAuth.where('source_type', 'company').with_('source').paginate()

i can get correct response, but if i need to filter some servcies, like this:

adminAuth = AdminAuth.where('source_type', 'company').where_has('source', lambda q: q.where('status', 1)).paginate()

or

adminAuth = AdminAuth.where('source_type', 'company').has('source').paginate()

both of them are wrong, the exception shows:

orator.exceptions.query.QueryException: (1054, "Unknown column 't1_admin_auth.None' in 'where clause'")
 (SQL: SELECT COUNT(*) AS aggregate FROM `t1_admin_auth` WHERE `source_type` = %s AND
 (SELECT COUNT(*) FROM `t1_admin_auth` WHERE `t1_admin_auth`.`source_id` = `t1_admin_auth`.`None`) >= %s 
(['company', 1]))

it seems the sql is wrong ,so if there is an way to slove my problem?
