First you have to create many2one field of product.product and then you can create one2many field.
For example:
`partent_id`: fields.many2one('product.product', 'Parent Product', ondelete='cascade'),
`product_ids`: fields.one2many('product.product', 'parent_id', 'Products'),
Thanks for your reply
but it still gives the integrity error
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]
Hi,
I also have created that one2many field on same model . it works but their are no records are being displayed in one2many field .
How to display value in one2many .
you got solution to this?
if you ask something like this:
model "product.product"
fields in the same model: product_parent_id, product_children_ids
when you try running the program this show some integrity error with the fields ids that should be into list product_children_ids,
you should solve with something like this, creating domain for this filed into the xml and some additional field into model like "type_product" if haven't anyone like this field to refer:
TYPE_MODE = [('product','product'),('subproduct','subproduct')]
model ("product.product")
type_product = fields.Selection(TYPE_MODE , 'Product Type', default='product', store=True)
xml (form_view for "product.product")
<field name="product_children_ids" domain="[('type_product','=','subproduct')]">
<tree>
<field name="code"/>
<field name="descripcion"/>
<field name="other_product_field_name"/>
</tree>
</field>
if this solve work for you, make me know.
Post the code, please
