<p>When you define a view you can specify on the relational fields a domain
attribute. This attribute is evaluated as filter to apply when displaying
existing records for selection.</p>

<h2><a class="toc-backref" href="#id1">Usage</a></h2>
<p>When you define a view you can specify on the relational fields a domain
attribute. This attribute is evaluated as filter to apply when displaying
existing records for selection.</p>
<pre>
<code lang="xml"><field name="product_id" domain="[('type','=','product')]"/></code>
</pre>
<p>The value provided for the domain attribute must be a string representing a
valid Odoo domain. This string is evaluated on the client side in a
restricted context where we can reference as right operand the values of
fields present into the form and a limited set of functions.</p>
<p>In this context it's hard to build complex domain and we are facing to some
limitations as:</p>
<blockquote>
<ul class="simple">
<li>The syntax to include in your domain a criteria involving values from a
x2many field is complex.</li>
<li>The right side of domain in case of x2many can involve huge amount of ids
(performance problem).</li>
<li>Domains computed by an onchange on an other field are not recomputed when
you modify the form and don't modify the field triggering the onchange.</li>
<li>It's not possible to extend an existing domain. You must completely redefine
the domain in your specialized addon</li>
<li>etc...</li>
</ul>
</blockquote>
<p>In order to mitigate these limitations this new addon allows you to use the
value of a field as domain of an other field in the xml definition of your
view.</p>
<pre>
<code lang="xml"><field name="product_id_domain" invisible="1"/>
<field name="product_id" domain="product_id_domain"/></code>
</pre>
<p>The field used as domain must provide the domain as a JSON encoded string.</p>
<pre>
<code lang="python">product_id_domain = fields.Char(
compute="_compute_product_id_domain",
readonly=True,
store=False,
)
@api.depends('name')
def _compute_product_id_domain(self):
for rec in self:
rec.product_id_domain = json.dumps(
[('type', '=', 'product'), ('name', 'like', rec.name)]
)</code>
</pre>
