odoo 9 - Field does not exist

问题

follow the documentation Odoo 9.0, I created a new module which I created a new model as follows:

models.py

# -*- coding: utf-8 -*-

from openerp import models, fields, api

class payModel(models.Model):
    _name = 'payModel.payModel'
    _inherit = 'hr.employee'

    num_CN = fields.Char("CN°")

and my form view:

<record model="ir.ui.view" id="payModel_form_view">
    <field name="name">payModel.num_CN</field>
    <field name="model">hr.employee</field>
    <field name="inherit_id" ref="hr.view_employee_form"/>
    <field name="arch" type="xml">
        <data>
            <xpath expr="//field[@name='bank_account_id']" position="after">
                <field name="num_CN"/>
            </xpath>
        </data>
    </field>
</record>

I verirfy in Settings -> Technical -> Database Structure -> Models that the model and the field were added by success But I get this error :

the num_CN does not exist

I try to add this field in employee form view by developer mode but I get the same error!

Can sameone help me what's missing?

回答1:

First of all - about your model.

_name = 'payModel.payModel' means that when you install module Odoo will create new table with name payModel_payModel. After this in the system will be your custom object - payModel.payModel.

_inherit = 'hr.employee' means that you expand table hr_employee(Odoo object - hr.employee).

If you want to create new table and use your new object you need to remove _inherit = 'hr.employee'. If you need to extend the hr.employee(for example add new fields or add some logic to model etc.) you need to remove _name = 'payModel.payModel'

Second problem which can be it is dependencies. If your module depends from hr module you need to mark this in __openerp__.py of your module:

'depends': ['hr'],

And one more thing. Make sure that models.py is imported in __init__.py of your module. Restart openerp-server before updating your module after changes in .py files. Odoo does not see changes in .py files without restart.

Hope this helps you.
