Question

我正在研究模块。它有一个按钮，其名称是创建的，如下面的代码所示。

<button name="creates" string="Create" type="object" groups="base.group_erp_manager" />

def creates(self,cr,uid,ids,context=None):
    for id in ids:
        deg_obj=self.pool.get('deg.form').browse(cr,uid,id)
    pr=int(deg_obj.categg_temp)
    ctx=dict(context)
    ctx.update({'default_pr':pr})

    return{
        'view_type': 'form',
        'view_mode': 'form',
        'res_model': 'product.product',
        'context': ctx,
        'type': 'ir.actions.act_window',
        'target': 'current',
    }

当我点击此按钮时，我得到了

Integrity Error

The operation cannot be completed, probably due to the following:
- deletion: you may be trying to delete a record while other records still reference it
- creation/update: a mandatory field is not correctly set

[object with reference: name - name]

在我的服务器日志中我有

我的第一个问题是。为什么我的sql insert命令出错，尽管没有像creates方法那样的插入。它只是打开一个表单，我将按下保存按钮或其他东西以节省价值。其次，我如何绕过这个并转到我可以创建项目的下一步。

注意：我也有编辑，查看方法和按钮，只需在查看和编辑模式下打开值。但也有同样的问题。

修改

有一点我必须提到。我有print "\n\n Inside Create Method" 在creater方法。它永远不会显示在我的服务器控制台/终端上。

EDIT1 deg_form有`_inherit ='product.product'

Answer 1

我很确定你班上的_inherit='product.product'打破了这些事情。

您的原始表单（不是您尝试使用按钮打开的表单）正在尝试在执行按钮操作之前保存对象。由于此表单处理的是继承产品。产品＆＃39;，您的表单正在尝试使用＆product;产品＆＃39; （并分别在 - ＆lt; product_template＆＃39;）表中。我认为您的表单没有提供足够的字段来满足所需的产品_模板＆＃39;字段。

您确定需要继承吗？在我看来，你不需要它。

建议：在代码中使用print（）代替使用PDB：

import pdb; pdb.set_trace()

它非常强大，并且对OpenERP有很大的帮助。

为什么在按钮单击OpenERP时插入命令
