                                                <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>
