<h2><a class="toc-backref" href="#id1">Usage</a></h2>
<p>Many2manyCustom field is useful when a direct access to the relational table
is needed, for example to be editable in a dedicated tree view.</p>
<p>Let's consider following models:</p>
<pre>
<code lang="python">class MyModelA(models.Model):
_name = 'my.model.a'
my_model_b_ids = fields.Many2manyCustom(
'my.model.b',
'my_model_a_b_rel',
'my_model_a_id',
'my_model_b_id',
create_table=False,
)
class MyModelB(models.Model):
_name = 'my.model.b'
my_model_a_ids = fields.Many2manyCustom(
'my.model.a',
'my_model_a_b_rel',
'my_model_b_id',
'my_model_a_id',
create_table=False,
)
class MyModelABRel(models.Model):
_name = 'my.model.a.b.rel'
my_model_a_id = fields.Many2one(
'my.model.a',
required=True,
index=True, # Index is mandatory here
)
my_model_b_id = fields.Many2one(
'my.model.b',
required=True,
index=True, # Index is mandatory here
)</code>
</pre>
<p>By setting <cite>create_table=False</cite> on the Many2manyCustom field, and using the
relational table name, as <cite>_name</cite> for the relational model, we're able to
define a dedicated tree view for <cite>my.model.a.b.rel</cite>.</p>
<pre>
<code lang="xml"><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" />
</tree>
</field>
</record></code>
