title: Is it possible to use QWeb template in Form view?
body: <p>I tried to use QWeb Template in a custom view. I don't find any documentation explaining this, any reference?</p>
  <p>Here's the sample code:</p>
  <pre><code>&lt;record id=&quot;realestate_property_view_form&quot; model=&quot;ir.ui.view&quot;&gt;
      &lt;field name=&quot;name&quot;&gt;realestate.property.form&lt;/field&gt;
      &lt;field name=&quot;model&quot;&gt;realestate.property&lt;/field&gt;
      &lt;field name=&quot;arch&quot; type=&quot;xml&quot;&gt;
          &lt;form string=&quot;Property&quot;&gt;
              &lt;header&gt;
                  &lt;button name=&quot;approve_action&quot; type=&quot;object&quot; string=&quot;Approve&quot;/&gt;
              &lt;/header&gt;
              &lt;sheet&gt;
                  &lt;group&gt;
                      &lt;group&gt;
                          &lt;field name=&quot;name&quot; /&gt;
                          &lt;field name=&quot;address&quot; /&gt;
                      &lt;/group&gt;
                      &lt;template&gt;
                          &lt;t t-name=&quot;templatePreviewBox&quot;&gt;
                              &lt;div&gt;
                                  &lt;img t-attf-src=&quot;'http://localhost:3000/rest/api/' + record.image_url.raw_value&quot; /&gt;
                              &lt;/div&gt;
                          &lt;/t&gt;
                      &lt;/template&gt;
                  &lt;/group&gt;
              &lt;/sheet&gt;
          &lt;/form&gt;
      &lt;/field&gt;
  &lt;/record&gt;
  </code></pre>
  <p>The problem is that if I inspect element in the browser, it's still displayed as <code>&lt;img t-attf-src&gt;</code> instead of <code>&lt;img src&gt;</code>, and the string expression seems not evaluated.</p>
  <p>I find the documentation in Odoo official site is not complete enough, so I really appreciate for any references or documentation about this QWeb.</p>
