Today i wondered how to add the description to the order report. What has to be done is find a link from the object which gets looped ([[repeatIn(o.order_line,’line‘)]]) to the description field. Here comes the general step-by-step approach on how to do that in openerp. I assume you use the gtk client.

  1. Our starting point is the sale.order report, so we open Administration->Low Level Objects->Actions->Report XML. Where we look for order and see ir.actions.report.xml and sale.order.

  2. Now we check what fields sale.order has, so we open Administration->Customization->Database structure->Objects and look for sale.order, which has a field order_line with a one2many relation (remember that: [[repeatIn(o.order_line,’line‘)]]? this is where the order_line object is being looped).

  3. Now we look at the sale.order.line object and see a reference to product_id which is a many2one field.

  4. Now check the product.product object and look for product_tmpl_id (product.template).

  5. And finally on our path we reach product.template and inside it a field called description, thats what we need, so we basically have the path from sale.order to the product description, we just need, to concatenate it.

</ol>

And this is the result: line.product_id.product_tmpl_id.description
And to get it working in our report template we use it like that:

[[ line.product_id.product_tmpl_id.description or removeParentNode(‚tr‘) ]] or

[[ line.product_id.product_tmpl_id.description or “ ]] or

[[ line.product_id.product_tmpl_id.description or removeParentNode(‚para‘) ]]

Thats it.

Special thanks go to alex_joni from the #openobject irc channel who guided me through the tour and showed me the simplicity of openerp. I hope this helps some people.
