找不到 'job.card.desc' 的参考字段 'project_id'

Question

我有两个模块，它们相互关联，但显示错误 There is no reference field found

请告诉我我错过了什么

我的 job.card.desc 模块如下所示：

class jobCardDesc(models.Model):

_inherit                =   'job.card.desc'
project_id          =   fields.Many2one('mrp.projects', string="Project ID")

和mrp.projects喜欢这样

class project_mrp(models.Model):
_name                   =   'mrp.projects'
name                    =   fields.Char(string = "Project Name")
code                    =   fields.Char(string = "Project Code", default = 'New')
jobCardIds              =   fields.One2many('job.card.desc','project_id',string="Job Card Ids")

Answer 1

我通过添加

得到了这个工作

project_id          =   fields.Many2one('mrp.projects', string="Project ID")

直接在模块 'job.card.desc' 中，而不是在继承的 中添加 project_id 字段job.card.desc 模块

找不到 'job.card.desc' 的参考字段 'project_id'

There is no reference field 'project_id' found for 'job.card.desc'
