Tanzil,

Add link for each object of the thumbnail  like this

<a t-att-href="'/foo/(slug(obj))">
     <!--Print object-->
     <t t-esc="obj.name"/>
</a>

In the controller

@http.route(['/foo/<model("Your.Model"):obj>'], type='http', auth='public', website=True)
def action_foo(self, obj, **post):
     return request.website.render('Your_Module.Your_Template', {'object', obj})

Pint the value of that object in temlate

<template id="Your_Module.Your_Template">
     ..................
     <t t-esc="object.name"/>
</template>

All the best !
