I am in odoo18 and currently on the Receipt page. At the bottom section of this page, there is a tab called Operations which contains the product lines. I want to make this entire section read-only except for the hamburger icon (the “lot” action button) that allows adding lots to the products.
In hamburger button:
First, I used this code to make the entire section read-only, but it also disabled the hamburger icon, so I could not add lots at all:
<xpath expr="//field[@name='move_ids_without_package']" position="attributes">
<attribute name="readonly">
state == 'done' or approval_editable_has_po != 'edit_approved'
</attribute>
<attribute name="force_save">1</attribute>
</xpath>
Then, I changed the code by setting each individual column to read-only, leaving only the hamburger icon editable:
<xpath expr="//field[@name='move_ids_without_package']/list/field[@name='product_id']" position="attributes">
<attribute name="readonly">parent.state == 'done' or parent.approval_editable_has_po != 'edit_approved'</attribute>
<attribute name="force_save">1</attribute>
</xpath>
(…and similar XPaths for other columns)
The result is: all columns are read-only, so users cannot add new products — which is correct — and the hamburger icon still works, which is also what I want.
However, I also want to hide the “Add a line” button.
I tried:
<xpath expr="//field[@name='move_ids_without_package']/list" position="attributes">
<attribute name="create">0</attribute>
</xpath>
This hides Add a line, but it disappears permanently.
Then I tried adding conditions:
<xpath expr="//field[@name='move_ids_without_package']/list" position="attributes">
<attribute name="create">
parent.state != 'done' or parent.approval_editable_has_po == 'edit_approved'
</attribute>
</xpath>
But this does not work — look like the create attribute seems to accept only True/False/1/0 and ignores domain-like expressions.
My question is:
Is it possible to hide the “Add a line” button conditionally (based on state and approval fields) while still keeping the hamburger icon editable?
