python - 在 OpenERP 7 中按下按钮时如何获取工作流程状态中的日期？

Question

您好，我有一个状态为待定、已批准和已完成的工作流程，我正在尝试在“WO_APPROVE_DATE”字段中自动获取日期，当按下已批准按钮时，我该如何实现？请帮忙..

按钮

<header> 
<button name="pending_draft" string="Pending" states="pending" class="oe_highlight"   type="workflow"/>
<button name="approved_draft" string="Approved" states="approved" class="oe_highlight" type="workflow"/>
<button name="complete" string="Active" states="active" class="oe_highlight" type="workflow"/>
</header>

类

class work_order(osv.osv):


sel_states = [
    ('pending', 'Pending'),
    ('approved', 'Approved'),
    ('active', 'Complete')
]

_name = "work_order.work_order"
_description = "Work Order Details"

_rec_name = "WO_CODE"
_columns = {
    'WO_CODE' : fields.char("Work Order Code", size=64, required=True, readonly=True ),
    'WO_ASSIGNED_TO' : fields.many2one("hr.employee", "Assigned To", ondelete="no action", domain=[('job_id', '=', ('Crew Supervisor'))]),
    'WO_NOTES' : fields.text("Description"),
    'WO_APPROVE_DATE' : fields.datetime("EngineerApproval Date"),
    'state' : fields.selection(sel_states, "Workflow"),
}

def workorder_pending(self, cr, uid, ids):
    self.write(cr, uid, ids, {'state' : 'pending'})
    return True

def workorder_approved(self, cr, uid, ids):
    self.write(cr, uid, ids, {'state' : 'approved'})
    return True

def workorder_complete(self, cr, uid, ids):
    self.write(cr, uid, ids, {'state' : 'active'})
    return True

Answer 1

首先添加此行用于导入包

from openerp.tools import DEFAULT_SERVER_DATE_FORMAT, DEFAULT_SERVER_DATETIME_FORMAT, DATETIME_FORMATS_MAP, float_compare
import time
from datetime import datetime

然后像这样更改函数

def workorder_approved(self, cr, uid, ids):
        self.write(cr, uid, ids, {'state' : 'approved','WO_APPROVE_DATE':time.strftime(DEFAULT_SERVER_DATE_FORMAT)})
        return True
