OpenERP 7: Why inherited view isn't display?

Question

I'm trying to override the Deliver button from the Delivery Orders view (i.e. stock.picking.out) and the one in the related wizard (i.e. stock.partial.picking).

To do that I've created a custom module: compose_delivery_order.

deliver_button.xml

as a gist

<data>
    <!-- override: stock/wizard/stock_partial_picking_view.xml -->
    <record id="stock_partial_picking_delivery_form" model="ir.ui.view">
        <field name="name">compose_delivery_order.stock_partial_picking_delivery_form</field>
        <field name="model">stock.partial.picking</field>
        <field name="priority" eval="15"/>
        <field name="inherit_id" ref="stock.stock_partial_picking_form"/>
        <field name="arch" type="xml">
            <xpath expr="/form/footer//button[@name='do_partial']" position="replace">
                <button
                        name="do_partial"
                        string="picking delivery"
                        type="object"
                        class="oe_highlight"
                />
            </xpath>
        </field>
    </record>

    <!-- override: sale_stock/sale_stock_view.xml -->
    <record id="view_delivery_form" model="ir.ui.view">
        <field name="name">stock.picking.out.form</field>
        <field name="model">stock.picking.out</field>
        <field name="inherit_id" ref="stock.view_picking_out_form"/>
        <field name="view_id" ref="stock_partial_picking_delivery_form"/>
        <field name="arch" type="xml">
            <xpath expr="/form/header//button[@name='action_process']" position="replace">
                <button name="action_process" states="assigned" string="[Deliver]" type="object"
                        class="oe_highlight"/>
            </xpath>
        </field>
    </record>
</data>

Issue

The button on stock.picking.out is correctly replace, but the one in stock.partial.picking is not. When I check the Manage Views info I got:

So my view is detected but not selected as the default one it seems.

Question

How can I force the use of my view?

Answer 1

After a long search, try and test I finally discover that the button for the given view was overridden in python code.

So to modify the button, I had to override the method in my module

# override: stock/wizard/stock_partial_picking.py
class stock_partial_picking(osv.osv_memory):
    _inherit = 'stock.partial.picking'
    _rec_name = 'picking_id'
    _description = "Partial Picking Processing Wizard"

    def fields_view_get(self, cr, uid, view_id=None, view_type='form', context=None, toolbar=False, submenu=False):
        # override of fields_view_get in order to change the label of the process button and the separator accordingly to the shipping type
        if context is None:
            context = {}
        res = super(stock_partial_picking, self).fields_view_get(cr, uid, view_id=view_id, view_type=view_type,
                                                                 context=context, toolbar=toolbar, submenu=submenu)
        type = context.get('default_type', False)
        if type:
            doc = etree.XML(res['arch'])
            for node in doc.xpath("//button[@name='do_partial']"):
                if type == 'in':
                    node.set('string', _('_Receive'))
                elif type == 'out':
                    node.set('string', _('[_Deliver]'))
            for node in doc.xpath("//separator[@name='product_separator']"):
                if type == 'in':
                    node.set('string', _('Receive Products'))
                elif type == 'out':
                    node.set('string', _('Deliver Products'))
            res['arch'] = etree.tostring(doc)
        return res

Answer 2

There are 2 ways of referencing views in Odoo :

1. if a view is requested by (model, type), the view with the right model and type, mode=primary and the lowest priority is matched
2. when a view is requested by id, if its mode is not primary its closest parent with mode primary is matched

If your view is requested by priority then try setting priority to a lower value.
