爲One2many字段

Question

設置默認值我有一個類student_student具有像限定的one2many字段result_ids以下：

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, []) 

在另一側我有一個類 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) 

我想要做的是填充result_i帶有最後一堂課的科目列表，每當用戶嘗試創建新的學生檔案時，使用one2many字段中的default參數。 但是，每當我嘗試創建一個學生檔案，我得到這個錯誤Wrong values for student.student.result_ids。 無論如何要實現這一目標嗎？

Answer 1

我可以通過重寫default_get方法做到這一點：

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 

這是如何覆蓋default_get爲one2many領域。

幸得：Default values for one2many

Answer 2

我這裏不完全讓你的要求，但你可以試試下面的：

def _get_subjects(self): 
    subjects = self.env['schoolresults.subject'].search([]) 
    details = self.env['schoolresults.detail'] 
    for subject in subjects: 
     details |= details.new({'subject_id': subject.id}) 
    return details 

但解釋錯誤消息：你回國的schoolresults.subject一個記錄，但您的字段result_ids的編碼爲schoolresults.detail。這是絕對錯誤的;-)

Answer 3

result_ids = fields.Many2many("schoolresults.detail", "student_id", "School Results", default="_get_subjects") 

def get_default_lines(self): 
    obj = self.env['your.class.name'].search([]) 
    return obj 

嘗試增加many2many領域類。
