AttributeError：“布尔”对象没有属性“ _fields”-Odoo v8

Question

我只是在模型中添加了一些相关字段，其他一些字段也起作用，但是对于该模型，它们只是不起作用，这些是我的模型：

class book_block(models.Model):
    _name = 'book.block'

    name = fields.Char(string="Name")
    code = fields.Char(string="Code", size=11)
    size_code = fields.Many2one('bsi.book.block.size', string="Size")
    text_paper = fields.Many2one('text.paper', string="Text Paper")
    n_pages_one_color = fields.Integer(string="N° of pages 1 color")
    adnl_n_pages_one_color = fields.Integer(string="Additional N° of pages one color")

class mrp_worksheet_contract(models.Model):
    _name = 'mrp.worksheet.contract'

    @api.model
    def create(self, vals):
        if vals.get('name', 'New') == 'New':
            vals['name'] = self.env['ir.sequence'].next_by_code('mrp.worksheet.contract') or '/'
        return super(mrp_worksheet_contract, self).create(vals)

    name = fields.Char('Reference', required=True, index=True, copy=False, readonly='True', default='New')
    date = fields.Date(string="Date")
    book_block = fields.Many2one('book.block', string="Book Block")
    n_pages_one_color = fields.Integer(string="N of pages one color", related="book_block.n_pages_one_color")
    adnl_n_pages_one_color = fields.Integer(string="Additional N° of pages one color", related="book_block.adnl_n_pages_one_color")

book_block字段还可以， n_pages_one_color和adnl_n_pages_one_color字段附带了问题，这使我感到adnl_n_pages_one_color ：

AttributeError: 'bool' object has no attribute '_fields'

我不明白，它应该可以工作，我也看不到任何错误，即使book_block Many2one字段也可以，那么，这是怎么回事？

有任何想法吗？

Answer 1

可能是您需要从openerp导入“ _”。

from openerp.tools.translate import _

Answer 2

不引用布尔（非布尔）字段。 错误是根据_setup_related方法从_setup_related方法生成的（从tracebak： 文件“ C：\\ Program Files（x86）\\ Odoo 8.0-20170914 \\ server。\\ openerp \\ fields.py”，行514，在_setup_related中 ）。源代码：设置相关字段的属性。 因此，我建议您检查具有相关属性的任何字段。 并检查book_block模型中是否存在adnl_n_pages_one_color字段。
