Odoo 12上不存在字段

Question

我试图在Odoo 12中制作一个模块，但一直给我一个错误字段，但我已经在模型内部定义了该字段

已经检查过几次并更改了一些代码，但还是没有运气

model.py

class ProductProduct(models.Model):
    _inherit = 'product.product'

    isbn = fields.Char('ISBN Code', unique=True, help="Shows International Standard Book Number")
    catalog_num = fields.Char('Catalog Number', help="Shows Identification Number of Books")
    lang = fields.Selection(string='Language', selection='_get_lang')
    author_id = fields.Many2one('res.partner','Author',domain=[('penulis','=',True)])
    publisher_id = fields.Many2one('res.partner','Publisher',domain=[('penerbit','=',True)])
    nbpage = fields.Integer('Number of Pages')
    location_id = fields.Many2one('stock.location', 'Location', help="Shows position of book", domain=[('lokasi buku','=',True)])
    num_edition = fields.Integer('No. Edition', help="Edition number of book")
    resensi = fields.Text('Resensi')
    state = fields.Selection([('available','Available'),('rent','Rented')],'State',readonly=True, default='available')

    _sql_constraints = [
        ('unique_barcode','unique(barcode)', 'barcode field must be unique across all the products'),
        ('code_uniq', 'unique (default_code', 'Code of the product must be unique!')
    ]

    @api.model
    def _get_lang(self):
        return self.env['res.lang'].get_installed()

view.xml：

    <record model="ir.ui.view" id="buku_tree_view">
        <field name="name">buku.tree</field>
        <field name="model">product.product</field>
        <field name="arch" type="xml">
            <tree string="Buku">
                <field name="default_code"/>
                <field name="name"/>
                <field name="publisher_id"/>
                <field name="author_id"/>
                <field name="location_id"/>
                <field name="categ_id"/>
                <field name="state"/>
            </tree>
        </field>
    </record>

我不断收到“字段publisher_id不存在”的信息，但是正如您所看到的，我已经在model.py中定义了它。

错误消息：

有人知道我的代码有什么问题吗？

Answer 1

如果您一次在模型（.py文件）和视图中添加了该字段，则会收到此错误。尝试在视图中注释该字段，然后再次运行，您可以在视图中取消注释。

Answer 2

您的代码完全正确，问题可能出在您将 .py文件添加到 init .py文件中。

1. 将model.py文件导入 init .py文件
2. 由于发生xml错误，odoo无法接受此更新，因此请在部分数据下的清单 .py中注释xml文件。
3. 现在重新启动更新，现在取消注释xml重新启动，升级它应该可以了。

Answer 3

我发现必须在安装模块之前安装“库存”模块。谢谢大家。
