This page of the documentation describes variables that can be used in a t-foreach loop in Qweb, but doesn't provide any examples of how to access those variables. I was thinking that I could use the $as_index variable to list line numbers on a sales order, but everything I have tried causes an error. Can anyone provide an example of how to output the index? Or, even better, the index + 1, since it starts at zero?

try this code inside table,
<t t-set="i" t-value="1"/>
<tr t-foreach="o.order_line" t-as="l">
<td> <span t-esc="i"/> </td>
<t t-set="i" t-value="i+1"/>
</tr>
That's what I came up with, too. Just wanted to know how to do it in the manner described in the "documentation".

I got the $as_index variable to work. Here is an example:
<tr t-foreach="o.order_line" t-as="l">
<td>
<span t-esc="l_index + 1" />
. . .
The index is zero-based, hence the addition of 1. Hope this helps.
This is pretty simple and straight forward.
When we define our loop like this:
<code>
<t t-foreach="people" t-as="person">
<tr>
<th scope="row"><span t-raw="person_index"/></th>
<td><span t-field="person.name"/></td>
<td><span t-field="person.age"/></td>
<td><span t-raw="person.weight"/></td>
</tr>
</t>
</code>
To get the current index/position of the person with the loop you can do person_index. i.e your variable_index or any other available variable withing the context of qweb loop.
I have tryed this:
<t t-set="i" t-value="1"/>
<tr t-foreach="o.order_line" t-as="l">
<td> <span t-esc="i"/> </td>
<t t-set="i" t-value="i+1"/>
</tr>
When the loop finishes, the ounter resets to 1. Does anyone kow a way to update a variable outside the loop? I would like to define a variable before the loop and set it to false. If I find what I am looking for inside the loop I would like to set the value of the variable to True. This var would later be used as a condition if a div is visible or not.
Any help is appreciated. Thx
var_index is automatically defined
Check https://www.odoo.com/documentation/8.0/reference/qweb.html#loops
Yes, that is the page I linked in my question. What I was hoping for was an example of usage. Everything I tried resulted in an error.
@Antony Lesuisse, Thanks for the link. I'm currently building a community module to add multiple product images for use in the website e-commerce pages here: https://github.com/OdooCommunityWidgets/website_multi_image unfortunately i've only just begun playing around with Odoo development and I have hit a brick wall trying to figure out how to create a t-foreach loop to output all images in the one2many in this module. Do you have any suggestions on how I could achieve this in 8.0?
