<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 class="code xml literal-block">

<span class="nt"><field</span> <span class="na">name=</span><span class="s">"product_id"</span> <span class="na">domain=</span><span class="s">"[('type','=','product')]"</span><span class="nt">/></span>
|
||
</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 class="code xml literal-block">

|
||
</pre>
|

<p>The field used as domain must provide the domain as a JSON encoded string.</p>
