These are also listed next to the input field on the sequence form view.</p> <p>If you want to add more variables for use in the expression, you can extend this module.</p> <p>Use cases for this module could be:</p> <ul class="simple"> <li>You want to generate alphanumeric numbering</li> <li>You want to apply some math to the number to prevent customers from knowing their place in the sequence</li> <li>You want to use UUID</li> </ul> <p><strong>Table of contents</strong></p> <div class="contents local topic" id="contents"> <ul class="simple"> <li><a class="reference internal" href="#usage" id="id1">Usage</a></li> <li><a class="reference internal" href="#bug-tracker" id="id2">Bug Tracker</a></li> <li><a class="reference internal" href="#credits" id="id3">Credits</a><ul> <li><a class="reference internal" href="#authors" id="id4">Authors</a></li> <li><a class="reference internal" href="#contributors" id="id5">Contributors</a></li> <li><a class="reference internal" href="#maintainers" id="id6">Maintainers</a></li> </ul> </li> </ul> </div> <a name="usage"></a> <h2><a class="toc-backref" href="#id1">Usage</a></h2> <p>To use this module, you need to:</p> <ul class="simple"> <li>Go to the form view of an <cite>ir.sequence</cite> record</li> <li>Go to the Python tab</li> <li>Enable the 'Use Python' checkbox</li> <li>Change the default 'number' expression to something more fancy.</li> </ul> <p>Examples:</p> <pre> <code lang="python"># To separate the Odoo-generated number with hyphens eg. 0-0-0-0-1 '-'.join(number_padded) # To have an UUID as the sequence value uuid.uuid4().hex # To use an 8-digit binary number '{0:#010b}'.format(number + 300)[2:]</code> </pre> <p>And so on.</p> <a name="bug-tracker"></a> <h2><a class="toc-backref" href="#id2">Bug Tracker</a></h2> <p>Bugs are tracked on <a class="reference external" href="https://github.com/OCA/server-tools/issues">GitHub Issues</a>.
