如何從視圖中獲取過濾數據？

Question

我加入這個模塊base.candidat我想開一個特定的候選人（即具有相同的電子郵件作爲候選）的應用程序模塊「基地Candidat」我加入這個功能base_candidat.py

class base_candidat(osv.osv): 
    _columns = { 
     'candidat_name': fields.char('Candidat', size=128, required=True), 
     'blacklist': fields.boolean('Blacklist'), 
     'email_candidat': fields.char('Email', size=32), 
     'mobile': fields.char('Mobile', size=32), 
     'priority': fields.selection(AVAILABLE_PRIORITIES, 'Appreciation'), 
     'user_id': fields.many2one('res.users', 'Responsable'), 
     'specialite': fields.many2one('base.candidat.specialite', 'Spécialité'), 
    } 

    def action_get_applications(self, cr, uid, ids, context=None): 
     modelDataClass = self.pool.get('ir.model.data') 
     hrApplicantClass = self.pool.get('hr.applicant') 

     model, action_id = modelDataClass.get_object_reference(cr, uid, 'hr_recruitment', 'action_hr_job_applications') 
     action = self.pool.get(model).read(cr, uid, action_id, context=context) 
     email_ids = self.browse(cr, uid, ids[0], context).email_candidat 
     candidature_ids = hrApplicantClass.search(cr, uid, [('email_from', '=', email_ids)], context=context) 

     action['context'] = {'default_res_model': self._name, 'default_res_id': ids[0]} 
     action['domain'] = str([('candidature_ids', 'in', email_ids)]) 

     return action 

我沒有結果。有什麼建議麼？？

如果我很清楚，'action'是一個不允許的變量名。如果你使用它，程序將不一致。 （有同樣的情況「主動」）

在我看來，這個領域表情不是這一行正確：
action['domain'] = str([('candidature_ids', 'in', email_ids)])
因爲這意味着你的模型具有candidature_ids領域，但該模型還沒有，所以這種情況下可以」不滿意，所以當你使用它時你看不到任何記錄。
您的概念的另一個問題，email_ids是字符串（不是數字，所以變量名稱是欺騙性的）並且candidature_ids是一個數字列表。

在我看來，你想寫一個函數字段。這是一個示例代碼，它可能不是最佳性能，但我認爲它會幫助您瞭解功能領域的本質：

def _getApplications(self, cr, uid, ids): 
    hrApplicantClass = self.pool.get('hr.applicant') 

    # get all of candidate 
    candidateDatas = self.read(cr, uid, ids, ['email_candidat']) 

    # collect all of emails 
    emails = [] 
    for candidate in candidateDatas: 
     if candidate['email_candidat'] not in emails: 
      emails.append(candidate['email_candidat']) 

    # get all of relevant applicant 
    applicantIds = hrApplicantClass.search(cr, uid, [('email_from', 'in', emails)]) 
    applicantDatas = hrApplicantClass.read(cr, uid, applicantIds, ['email_from']) 

    # pair base_candidat id with application id 
    retVal = {} 
    for candidate in candidateDatas: 
     retVal[candidate['id']] = [] 
     if not candidate['email_candidat']: 
      continue 
     else: 
      for applicant in applicantDatas: 
       if applicant['email_from'] == candidate['email_candidat']: 
        retVal[candidate['id']].append(applicant['id']) 

    return retVal 

# the field definition 
'application_ids': fields.function(_getApplications, method=True, type='one2many', 'Applications')
