Question

我有多个Many2many字段，但出现以下错误：

关系流不存在，未定义表

我找不到发生此错误的位置。有人可以帮我解决此错误吗？

class College(models.Model):
_name = 'module5_college'
_description = 'College Info'
_rec_name = 'clg'

clg = fields.Char("College Name")
uni = fields.Char("Affiliated to")
cou = fields.Many2many('module5_stream',string="Stream")


class Stream(models.Model):
_name = 'module5_stream'
_description = 'Stream info'
_rec_name = 'cou'

cou = fields.Selection([
    ('BTECH', 'BTECH'),
    ('MTECH', 'MTECH'),
    ('MCA', 'MCA')],"Stream")

cou_mode = fields.Selection([
    ('Regular','Regular'),
    ('Lateral','Lateral'),
    ('Distance','Distance')],"Course Mode")

sem_no = fields.Integer("No of semesters")
# full_score = fields.Integer(compute='score_calc',string="Score")
sem = fields.Many2many('module5_sem',"Semesters")


class Semester(models.Model):
 _name = 'module5_sem'
 _rec_name = 'id'

 sem_no = fields.Char("Semester No")
 sub = fields.Many2many('module5_subject',"Subjects")

Answer 1

您必须遵循此示例，因为这是创建 many2many 字段的方法：

employees_ids = fields.many2many('Employees.Employees', 'tasks_employees_rel', 'task_id', 'employee_id', 'Employees assigned to task')

给你一个更好的例子。

可以将一个员工分配给许多任务

可以将任务分配给许多员工

因此您有一个many2many关系，这意味着您必须创建一个包含两个键的新表。

Many2Many字段表未定义的Odo，无法获取多个Many2Many字段
