<h3>How to define a computed field</h3>
<p>Computed fields are defined with the fields
<strong>Dependencies</strong> and <strong>Compute</strong>.</p>
<p>The field <strong>Dependencies</strong> lists the fields that
the current field depends on. It is a comma-separated list of
field names, like <code>name, size</code>. You can also refer to
fields accessible through other relational fields, for instance
<code>partner_id.company_id.name</code>.</p>
<p>The field <strong>Compute</strong> is the Python code to
compute the value of the field on a set of records. The value of
the field must be assigned to each record with a dictionary-like
assignment.</p>
<pre>
for record in self:
record['size'] = len(record.name)
</pre>
<p>The only predefined variables are</p>
<ul>
<li><code>self</code> (the set of records to compute)</li>
<li><code>datetime</code> (Python module)</li>
<li><code>dateutil</code> (Python module)</li>
<li><code>time</code> (Python module)</li>
</ul>
<p>Other features are accessible through <code>self</code>, like
<code>self.env</code>, etc.</p>
