Odoo 9. How to override form widgets?
<p>I work with odoo <strong>9</strong>. In the system exists <em>render_value</em> method for each type of field: </p>

<pre><code>/odoo/addons/web/static/src/js/views/form_widgets.js
/odoo/addons/web/static/src/js/views/form_relational_widgets.js
</code></pre>

<p>How I can use my custom method <em>render_value</em>(for example in <strong>FieldChar</strong>) for all forms? And how I can use specific <em>render_value</em> for one form or one module? </p>

<p>I created <code>form_widgets.js</code> in my module, but I not understand how properly override Field.</p>

<pre><code>odoo.define('my_module.form_widgets', function (require) {
"use strict";

// what I should do here???

});
</code></pre>

<p>Can you provide small example? Thank in advance.</p>
