In the official document: https://www.odoo.com/documentation/12.0/reference/qweb.html, It says "esc takes an expression, evaluates it and prints the content", where does this value come from? From my_module.py in module or from javascript in the same xml?
To be more specific, I have a CharField called "my_link" (let's suppose its id is "my_app.my_module.my_link"), which is a link like "//www.odoo.com" in my_module.py, and I want to transfer it to my frontend page my_frontend.xml, and engage it in the html iframe code as the value of the attribute "src", so what should I do?
My xml is most likely to this: (sorry for not showing the indent, the editor eats them all)
<record model="ir.ui.view" id="my_app.my_module_form">
<field name="name">My Module Form</field>
<field name="model">my_app.my_module</field>
<field name="arch" type="xml">
<form>
<sheet>
<t t-call="website.layout">
<body>
<div>
<!-- Below is where I want to transfer my value to -->
<iframe id="preview" t-att-src="row {{ my_app.my_module.my_link }}" scrolling="no"></iframe></div>
</body>
</t>
</sheet>
</form>
</record>
When I tried to run this xml, it just gives me the same code in the browser
<iframe id="preview" t-att-src="row {{ my_app.my_module.my_link }}" scrolling="no"></iframe>without render the value in it.
Anyone has some nice idea about this? Thanks a lot!
