This module adds a new Many2many custom field with a create_table attribute.

Table of contents


Many2manyCustom field is useful when a direct access to the relational table is needed, for example to be editable in a dedicated tree view.

Let’s consider following models:

class MyModelA(models.Model):

    _name = 'my.model.a'

    my_model_b_ids = fields.Many2manyCustom(

class MyModelB(models.Model):

    _name = 'my.model.b'

    my_model_a_ids = fields.Many2manyCustom(

class MyModelABRel(models.Model):

    _name = 'my.model.a.b.rel'

    my_model_a_id = fields.Many2one(
        index=True,  # Index is mandatory here
    my_model_b_id = fields.Many2one(
        index=True,  # Index is mandatory here

By setting create_table=False on the Many2manyCustom field, and using the relational table name, as _name for the relational model, we’re able to define a dedicated tree view for my.model.a.b.rel.

<record id="my_model_a_b_rel_tree_view" model="ir.ui.view">
    <field name="name">my.model.a.b.rel.tree.view</field>
    <field name="model">my.model.a.b.rel</field>
    <field name="arch" type="xml">
        <tree editable="top">
            <field name="my_model_a_id" />
            <field name="my_model_b_id" />
