However standard functionality does not yield this result.</p> <p>With this module installed sequence value is based on other sequences in the same list, which combined with <em>_order = 'sequence ASC'</em> allows to retain ordering of which records were created.</p> <p>What this module does:</p> <ul class="simple"> <li>Works only for records created in front-end</li> <li>Makes sure that new records gets highest or lowest sequence value depending on where record is inserted (in case of editable list &quot;top&quot; or &quot;bottom&quot;)</li> </ul> <p>What this module doesn't do:</p> <ul class="simple"> <li>Does not work for records created from back-end</li> <li>It does not ensure that first element has sequence = 1</li> <li>It does not check for continues sequence numbering (e.g. sequences like 1, 2, 5, 8 are possible)</li> <li>Does not ensure sequence uniqueness</li> </ul> <p><strong>Important</strong>: this module might create negative sequence numbers (e.g. in case of tree view <em>editable=top</em>)</p> <p><strong>Technical</strong>: The module injects computed sequence into context like so: <em>{&quot;default_sequence&quot;: &lt;value&gt;}</em>. This overrides defaults defined in <em>_defaults</em> dict. If you still want to provide your own sequence value you can do it by overriding <em>default_get()</em> function.</p> <a name="usage"></a> <h3>Usage</h3> <ul class="simple"> <li>Install this module</li> <li>Define new field <em>sequence = fields.Integer()</em></li> <li>Add sequence field in desired view (you can hide field with <em>invisible=&quot;1&quot;</em> if needed)</li> <li>Ensure ordering with <em>_order = 'sequence ASC'</em></li> </ul> <a name="known-issues-roadmap"></a> <h3>Known issues / Roadmap</h3> <ul class="simple"> <li>Fix negative sequence numbers</li> <li>Ensure continuous sequence numbering</li> </ul> <a name="credits"></a> <h3>Credits</h3> <a name="contributors"></a> <h4>Contributors</h4> <ul class="simple"> <li>Andrius Preimantas &lt;<a class="reference external" href="mailto:andrius&#64;versada.lt">andrius&#64;versada.lt</a>&gt;</li> </ul> <a name="maintainer"></a> <h4>Maintainer</h4> <a class="reference external image-reference" href="http://odoo-community.org"><img alt="Odoo Community Association" src="http://odoo-community.org/logo.png" /></a> <p>This module is maintained by the OCA.</p> <p>OCA, or the Odoo Community Association, is a nonprofit organization whose mission is to support the collaborative development of Odoo features and promote its widespread use.</p> <p>To contribute to this module, please visit <a class="reference external" href="http://odoo-community.org">http://odoo-community.org</a>.</p>
