为 One2many 字段设置默认值 [英] Set default values for One2many field

问题描述

我有一个 student_student 类，它有一个 one2many 字段result_ids，定义如下:

I have a class student_student which have a one2many fieldresult_ids defined like the following:

    result_ids = fields.One2many("schoolresults.detail", "student_id", "School Results", default="_get_subjects")

和

def _get_subjects(self):
     cr = self.pool.cursor()
     self.env
     return self.pool.get('schoolresults.subject').search(cr, self.env.uid, [])

在另一边我有一个班级schoolresults_subject:

in the other side I have a class schoolresults_subject:

class schoolresults_subject(models.Model):
    _name = "schoolresults.subject"
    _description = "Student's subjects."
    name = fields.Char("Subject")

class schoolresults_detail(models.Model):
    _name = "schoolresults.detail"
    _description = "Student's results."
    student_id = fields.Many2one("student.student", "Student", ondelete="cascade")
    subject_id = fields.Many2one("schoolresults.subject", "Subject")
    result = fields.Float("Result", compute='_compute_value', store=True)

我想要做的是使用 one2many 中的 default 参数，每当用户尝试创建新的学生档案时，用上一堂课的科目列表填充 result_ids场地.但是每当我尝试创建学生档案时，我都会收到此错误Wrong values for student.student.result_ids.请问有没有办法做到这一点?

What I'm trying to do is to fill the result_ids with a subjects list from the last class, whenever the user trying to create a new student profile, using the the default parameter in the one2many field. But whenever I try to create a student profile I get this error Wrong values for student.student.result_ids. Please is there anyway to achieve that?

附注.我正在使用 Odoo 9

推荐答案

我可以通过覆盖 default_get 方法来做到这一点:

I could do this by overriding the default_get method:

def default_get(self, fields):
    res = super(student_student, self).default_get(fields)
    srd = self.env['schoolresults.detail']
    ids=[]
    school_result={'subject_id':1,'result':0} #dict for fields and their values
    sr = srd.create(school_result)
    ids.append(sr.id)


    res['result_ids'] = ids
    return res

这是如何覆盖 one2many 字段的 default_get.

This is how to override default_get for one2many field.
