How to display a field in tree view based on a selection field value in Odoo?

Question

I have a scenario where a field has to be displayed based on value of the selection field.

class mro_order(osv.osv):
_inherit="mro.order"

 _columns={
        'released_part':fields.one2many('mro.released', 'released_id', 'Released parts',),
        'rel_id':fields.many2one('mro.released', 'Parts'),
        'parts_id1': fields.many2one('product.product', 'Parts', required=True, domain = [('maintain_ok','=',True)],),

    }

class mro_order_parts_line(osv.osv):



_inherit="mro.order.parts.line"

    _columns={
        'sts': fields.selection([
        ('new', 'New'),
        ('release', 'released'),

        ], 'State', default='new', readonly= False, select=True),
    }

    def onchange_sts(self, cr, uid, ids, sts):

            value = {}
            if sts == 'release':
                    value['parts_id'] = fields.many2one('mro.released','Parts')
            return value


class mro_released(osv.Model):
    _name="mro.released"

    _columns={
        'name': fields.char('Description', size=64),
            'parts_id': fields.char('Parts'),
            'parts_qty': fields.float('Quantity'),
            'parts_uom': fields.many2one('product.uom','Unit of Measure'),
            'released_id': fields.many2one('mro.order', 'Maintenance Order'),
        'state': fields.selection([
        ('scrap', 'Scrap'),
        ('reusable', 'Re-usable'),

        ], 'State', readonly= False, select=True, required=True),

    }



This is my xml file

<?xml version="1.0" encoding="utf-8"?>
<openerp>
    <data>
        <record model="ir.ui.view" id="released_parts_id">
                <field name="name">mro.order.form</field>
                <field name="model">mro.order</field>
                <field name="inherit_id" ref="mro.mro_order_form_view"/>
                <field name="arch" type="xml">
            <xpath expr="//form/sheet/notebook/page/group/field/tree/field[@name='parts_id']" position="before">
                <field name="sts" onchange="onchange_sts(sts)"/>
            </xpath>

            <xpath expr="//form/sheet/notebook/page/group[@string='Planned Parts']" position="after">
                            <group string="Released Parts">
                                        <field name="released_part" nolabel="1">

                                            <tree string="Released Parts" editable="bottom">
                                                <field name="parts_id" />
                                                <field name="parts_qty"/>
                                                <field name="parts_uom" />
                                                <field name="name"/>
                                            </tree>


                                        </field>
                                </group>

                    </xpath>
                </field>
            </record>
    </data>
</openerp>

Based on the value of selection field, I want to change the relation of a many2one field or based on the value of selection field replace another many2one field named 'A' with different relation to replace the other many2one field named 'B' with different relation in the tree view of xml.

Kindly anyone has any idea on this?

You can use attrs attribute for this.

attrs

dynamic attributes based on record values.

A mapping of attributes to domains, domains are evaluated in the context of the current row's record, if True the corresponding attribute is set on the cell.

Possible attributes are invisible (hides the button) and readonly (disables the button but still shows it)

Here for this define two fields separately and give the correct attrs attribute to view the correct one.

For Eg:- you can give attrs attribute like the following for the field you want to show when the selection field is "new"

attrs="{'invisible':[('sts', '!=', 'new')]}"

From the comments:- code for your condtion

                <field name="parts_id1" attrs="{'invisible':[('sts', '!=', 'new')]}"/>
                <field name="parts_id2" attrs="{'invisible':[('sts', '!=', 'release')]}"/>

Hope this helps.
