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:
|
|
|
|
``` 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
|
|
)
|
|
```
|
|
|
|
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.
|
|
|
|
``` 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>
|
|
```
