I define an ir.ui.view as follows:

    <record id="product_view_extension" model="ir.ui.view">
      <field name="name">Product View Extension</field>
      <field name="model">product.template</field>
      <field name="inherit_id" ref="product.product_template_form_view"/>
      <field name="arch" type="xml">
        ...

Inside the body of `arch`, I wish to iterate through a data structure generated on the server side. Here is a pseudo code of what I want on the server side:

p = the product.template being shown in ir.ui.view
result = []
for price_list in p.price_lists
  result.append(price_list.do_some_calculation())
make result available for view

However, for the case of `ir.ui.view`, there is no controller involved, so I don't know how to make `result` available for the view. 

Ultimately I want to be able to do something like this in the view: 

<t t-foreach="result" t-as="dict">     
    <div>            
        <span t-field="dict.field" />      
    </div>
</t>

Whereas `result` is the array generated above, and `hash` is a plain old Python dictionary.

This type of stuff is very simple to do in frameworks like Rails and Laravel, however, I can't figure out how to do it in Odoo.
