如何更改odoo中另一个型号的默认字段值

Question

如何在form_serial_no_id模型的plot.allocate模型的Many2one字段中将状态字段的默认值formdownload模型记录更改为true？

我已经写了一个方法来覆盖PlotAllocation模型的odoo创建函数，但它仍然没有将状态字段的值更改为true。相反，它会转到父类（plot.allocate）中create方法的override函数。无论何时我保存记录，控制都转到父方法的创建函数，并忽略继承plot.allocate模型的类PlotAllocation的创建函数。我怎样才能解决这个问题？

from openerp import models, fields, api 


class CompanyName(models.Model): 
    _name = 'companyname' 
    _rec_name = 'company_name' 

    company_name = fields.Char(string="Company Name", required=True) 
    company_short_code = fields.Char(string="Company short code", required=True) 


class FormDownload(models.Model): 
    _name = 'formdownload' 
    _rec_name = 'form_serial_no' 

    name = fields.Many2one('companyname', string="Company Name", ondelete='cascade', 
          required=True) 
    form_serial_no = fields.Char(string="Form Serial No", readonly=True) 
    status = fields.Boolean(string="Status", default=False) 

    @api.model 
    def create(self, vals): 
     serial_no = self.env['ir.sequence'].get('formdownload.form_serial_no') 
     code = self.env['companyname'].browse(vals['name']).company_short_code 

     # capitalize company short code values 
     code = code.upper() 

     # merge code and serial number 
     vals['form_serial_no'] = code + serial_no 
     return super(FormDownload, self).create(vals) 


class PlotAllocation(models.Model): 
    _inherit = 'plot.allocate' 

    form_serial_no_id = fields.Many2one('formdownload', 
             domain=[('status', '=', False)], 
             ondelete='cascade', string="Form Serial No") 

    def create(self, vals): 
     form_id = vals['form_serial_no_id'] 
     form_obj = self.env['formdownload'].browse(vals['status']) 

     if form_id: 
      form_obj.write({'status': True}) 

     return super(PlotAllocation, self).create(vals) 

这里是父类的创建覆盖功能

class plot_allocate(osv.osv): 
    _name = 'plot.allocate' 
    _inherit = ['mail.thread', 'ir.needaction_mixin']  

def create(self, cr, uid, vals, context=None): 
     offer_dt = vals.get('offer_dt') 
     offer_price = vals.get('offer_price') 
     plot_no = vals.get('plot_no') 
     payment_plan = vals.get('payment_plan') 
     # generate and store the offer letter reference number 
     vals['offer_letter_reference_number'] = self.pool.get(
      'ir.sequence').get(cr, uid, 'offer_letter_reference_number') 
     # override creation method to prevent creation of duplicate plots 
     if plot_no: 
      plot_no_duplicate = self.search(
       cr, uid, [('plot_no', '=', plot_no)]) 
      if plot_no_duplicate: 
       raise osv.except_osv(
        _('Duplicate!'), 
        _('Plot No is allocated or is open for allocation already')) 
     # change status of unallocated plots to allocated in unit_master 
     unit_master = self.pool.get('unit.master').browse(cr, uid, plot_no) 
     # change corresponding plot in unit_master to allocated 
     unit_master.write({'status': 'allocated'}) 
     project_and_plot_id = super(
      plot_allocate, self).create(
      cr, uid, vals, context=context) 
     plot = self.browse(cr, uid, project_and_plot_id, context=context) 
     if payment_plan: 
      self.calc_payment_plan(cr, uid, plot, offer_dt, payment_plan) 
     return project_and_plot_id 

Answer 1

试试这个：

@api.model 
def create(self, vals): 
    status = self.env['formdownload'].browse(vals['form_serial_no_id'])   
    if self.form_serial_no_id.id == status.status: 
     status.write({'status': True})  
    return super(PlotAllocation, self).create(vals) 

Answer 2

我想这代码，它工作得很好：

@api.model 
def create(self, vals): 
     rec_id = super(PlotAllocation, self).create(vals) 
     if rec_id.form_serial_no_id : 
      # raise exceptions.ValidationError('Your code is here should make the status of companyname to true') 
      # print 'Your code is here should make the status of companyname to true' 
      rec_id.form_serial_no_id.status = True 
     return rec_id 

Answer 3

试试这个：

@api.model 
def create(self, vals): 
    form_id = vals['form_serial_no_id'].id 
    form_obj = self.env['formdownload'].browse([form_id]) 

    if your condition: 
     form_obj.write({'status':True}) 

    return super(PlotAllocation, self).create(vals)
