Hello,

I find the attribute oldname in field definition.  Is there any use of oldname attribute?

'product_tmpl_id' : fields.many2one('product.template', 'Product Template', required=True, ondelete='cascade', select=True, oldname='product_id'),

Thanks in advance.

HI Shamji,

'oldname' is the attribute used at time of migration.

oldname (string) -- the previous name of this field, so that ORM can rename it automatically at migration


Hope this helps...

Is oldname helpful to rename the field even if it has records in the database?

For 'oldname' and 'rename_fields' parameters is used for rename the column name in database but if we used this parameter then we lost data of this column from db.
