Using xml_id for attrs

I want to hide some columns in sale order form depends to product selected.
I think i can use the product's xml_id like this :
<field name="myfield" attrs="{'invisible': [('product_id', '!=', ref('product.my_product'))]}"/>

but i have an error :

NameError: name 'ref' is not defined

What is wrong with my attrs? There is another method to hide a field when a particular product is selected?

Sorry valentin, you can't do this.

`ref()` can only be used inside `eval` XML attributes (which is evaluated by Odoo's `safe_eval` module) as in the following example:


If your product is well known (you're already referring it by their External-ID in your example), you may try referring other field with a known value, like the product `code` ("Internal Reference") or  `ean13` ("EAN13 Barcode"):

<field name="myfield" attrs="{'invisible': [('product_id.code', '!=', 'SOME.PRODUCT.CODE')]}"/>

Hi Valentine,

By overriding fields_view_get you can do so.

Reference: fields_view_get example

In Odoo10 you can do the following:

<field name="myfield" attrs="{'invisible': [('product_id','!=', %(other_module.xml_id)d)]}"/>

Whoops. Didn't read the entire question.

You can still use this for xml-id's in attrs at least...

I think you can't hide columns in tree view depending on some choices in the runtime. This is straightforward in form views and could be achieved using attrs tag.
