Question

Considering the following objects and a corresponding view:

class first_object(osv.osv):
    _name = "first.object"
    _columns = {
                'id': fields.integer ('First ID'),
                'flag': fields.boolean ('Flag'),
                'second_object_id': fields.one2many('second.object','first_object_id')
    }

class second_object(osv.osv):
    _name = "second.object"
    _columns = {
                'id': fields.integer ('Second ID'),
                'first_object_id': fields.many2one('first.object','random field'),
                'field_x': fields.float('x',size=128),
                'field_y': fields.float('y',size=128),
    }

<record model="ir.ui.view" id="first_object_view_id">
    <field name="name">Frist Object</field>
    <field name="model">first.object</field>
    <field name="type">form</field>
    <field name="arch" type="xml">
        <form>
            <notebook>
                <page>
                    <field name="id"></field>
                    <field name="flag"></field>
                    <field name="second_object_id">
                        <tree editable="top">
                            <field name="field_x" attrs="{'invisible':[('flag','=',True)]}"/>
                            <field name="field_y"/>
                        </tree>
                        <form>
                            <field name="field_x"/>
                            <field name="field_y"/>
                        </form>
                    </field>
                </page>
            </notebook>
        </form>
    </field>
</record>

Notice the attrs I have now for the field of the second object named field_x in the tree which is based on the field of the first object named flag.

First of all, the attribute in this case is ignored completely. I dont know why it wont work. Second, assuming this can’t work and the attributes MUST refer to local fields, the invisible attribute does not work for the tree view, just the form view. However, if you set a simple invisible=”1″ in the tree it would work just fine (I cant rely on that, I need the rule I provide with attributes). Any ideas?

EDIT:
The problem seems to be making fields invisible via attributes (and not invisible=”1″) in the TREE view. It works fine in the form. If this can be done it would solve my problem.

EDIT 2:
I tried with separated view definitions and local fields instead of many2one and one2many to no avail. However, I managed to somehow achieve this with invisible="context.get('xxx',True/False)". The problem is once the condition is matched, it remains invisible even after creating a new record where the condition is not matched.

Answer 1

it seems trying to set an conditional invisible attribute will not affect the true view. only invisible=”1″. which makes sense since i can’t imagine a tree view with some invisible field of which the entire column itself is not invisible.
