<p>This is a technical module. Its goal is to ease the play of onchange method directly called from Python code.</p> |

<h1><a class="toc-backref" href="#id1">Usage</a></h1> |
||||
|
<p>To use this module, you need to:</p> |
||||
|
<ul class="simple"> |
||||
|
<li>depend on this module</li> |
||||
|
<li>call <cite>yourmodel.play_onchanges(values, [‘field’])</cite></li> |
||||
|
</ul> |
||||
|
<p>Example if you want to create a sale order and you want to get the values relative to partner_id field (as if you fill the field from UI)</p> |
||||
|
<blockquote> |
||||
|
<p><cite>vals = {‘partner_id’: 1}</cite></p> |
||||
|
<p><cite>vals = self.env[‘sale.order’].play_onchanges(vals, [‘partner_id’])</cite></p> |
||||
|
</blockquote> |
||||
|
<p>Then, <cite>vals</cite> will be updated with partner_invoice_id, partner_shipping_id, pricelist_id, etc…</p> |
||||
|
<p>Default values will be used to process onchange methods, if respective fields are not set in <cite>vals</cite>. |
||||
|
You can get them if you pass fields name in the list of fields.</p> |
||||
|
<blockquote> |
||||
|
<p><cite>vals = {‘partner_id’: 1}</cite></p> |
||||
|
<p><cite>vals = self.env[‘sale.order’].play_onchanges(vals, [‘partner_id’, ‘date_order’])</cite></p> |
||||
|
</blockquote> |
||||
|
<p><cite>vals</cite> will contain, in addition to the changed values, the default value for <cite>date_order</cite></p> |
||||
|
<p>You can also use it on existing record for example:</p> |
||||
|
<blockquote> |
||||
|
<p><cite>vals = {‘partner_shipping_id’: 1}</cite></p> |
||||
|
<p><cite>vals = sale.play_onchanges(vals, [‘partner_shipping_id’])</cite></p> |
||||
|
</blockquote> |
||||
|
<p>Then the onchange will be played with the vals passed and the existing vals of the sale. <cite>vals</cite> will be updated with partner_invoice_id, pricelist_id, etc..</p> |
||||
|
<p>Behind the scene, <cite>play_onchanges</cite> will execute <strong>all the methods</strong> registered for the list of changed fields, so you do not have to call manually each onchange. To avoid performance issue when the method is called on a record, the record will be transformed into a memory record before calling the registered methods to avoid to trigger SQL updates command when values are assigned to the record by the onchange</p> |
||||
|
<p>Notes:</p> |
||||
|
<ul class="simple"> |
||||
|
<li>Order in onchange_fields is very important as onchanges methods will be played in that order.</li> |
||||
|
<li>If you use memory object in <cite>vals</cite>, be award that onchange method in base model call <cite>self.invalidate_cache()</cite> that reset it.</li> |
||||
|
</ul> |
