How can I pass context to a one2many field?

I have the following code:

class product_product(osv.osv):
    _name = 'product.product'
    _inherit = 'product.product'

    def test(self, cr, uid, ids, field_names=None, arg=None, context=None):
        result = {}
        if not ids: return result

        context['only_with_stock'] = True

        for id in ids:
            context['product_id'] = id
            location_obj = self.pool.get('stock.location')
            result[id] = location_obj.search(cr, uid, [('usage', '=', 'internal')], context=context)

        return result


    _columns = {
        'test': fields.function(test, type='one2many', relation='stock.location', string='Stock by Location'),
    }

product_product()

and:

<openerp>
    <data>

        <act_window
            context="{'product_id': active_id, 'only_with_stock': True}"
            id="act_stock_product_location_open"
            name="Stock by Location"
            res_model="stock.location"
            src_model="product.product"/>


        <record id="nfx_view_normal_procurement_locations_form" model="ir.ui.view">
            <field name="name">nfx_product.normal.procurement.locations.inherit</field>
            <field name="model">product.product</field>
            <field name="inherit_id" ref="stock.view_normal_procurement_locations_form"/>
            <field name="arch" type="xml">
                <group name="lot" position="before" version="7.0">
                    <group string="Locations" attrs="{'invisible': [('type', '=', 'service')]}" groups="base.group_user">
                        <field name="test" nolabel="1" context="{'product_id': active_id, 'only_with_stock': True}">
                            <tree string="Stock Location">
                                <field name="complete_name"/>
                                <field name="stock_real"/>
                                <field name="stock_virtual" invisible="'product_id' not in context"/>
                            </tree>
                        </field>
                    </group>
                </group>

            </field>
        </record>

    </data>
</openerp>

The test() function works well. It creates a one2many field with the stock locations. The complete_name field in the treeview is ok but the stock_real and stock_virtual fields are empty(0.00). I think because this fields calls _product_value() from stock/stock.py and _product_value() needs the product_id passed in the context. But it is not passed.

I wish this may help you:

    <field name="test" nolabel="1" context="{'default_product_id': active_id, 'default_only_with_stock': True}">

This worked like a charm. adding default_ before the field name eg default_product_id instead of product_id. Same can also be used to pass context in "create and edit" pop up as seen in the hr_expense.view_expenses_form view where groups_ref fields are set by context. if you try to create a new user from the expense form, some access right groups are automatically set.

Pls. try with line <field name="test" nolabel="1" context="{'product_id': active_id, 'only_with_stock': True}" options="{"always_reload": True}">

I have found the solution. The right way is indeed:

<field name="test" nolabel="1" context="{'product_id': active_id, 'only_with_stock': True}">

but there is a bug in OpenERP 7. The context is not passed. The bug is fixed and needs to be released. You can see and follow the fix here:

https://code.launchpad.net/~openerp-dev/openerp-web/7.0-opw-584668-cpa

On this page you can see the modifications and fix it youself until the oficial fix is released.

I have tried to download this branch and use it as my web folder, updated all the modules of my database, but it doesn't resolve the problem... Am I supposed to install all of OpenERP once more ?

With the line

<field name="test" nolabel="1" context="{'product_id': id, 'only_with_stock': True}">

you try to set the "product_id" to id. In this case the field id must be part of your view. Try to add an invisible field with the id:

<field name="id" invisible="1"/>

Hi, you can use active_id instead of id, with active_id, no need to add a field id invisible. Bye

both not working... :-(

I thought id was right because id is given in the URL...

Strange, the view is correct, since I saw this also in the account-addon. The problem must be in the function. You should remove method=True from the definition since this was only for v6.0. what is the value of the context within your function?

my function test is working well. It has the product_id in the context. The problem is the context is not passed to the fields <field name="stock_real"/> and <field name="stock_virtual"/>.

try to remove method=True. Please update your question, because there you are using the field "test" and not "stock_real"

I'm sorry, I have tested it again. My function test don't get's the product_id passed in the context too. As you can see above the product_id is added to the context from ids. So the search in my function test is working well but because the product_id is not passed from <field name="test" nolabel="1" context="{'product_id': id( or active_id), 'only_with_stock': True}">, the sub fields <field name="stock_real"/> and <field name="stock_virtual"/> don't has the product_id in their context...

method=True removed. Has no effect too... :-(

Ok. I would just try <field name="stock_real" context="{'product_id': parent.id}"/>

no, don't work too. I even have tried <field name="stock_real" context="{'product_id': 49}"/> with no effect...

Then I do not have any ideas. Maybe it is not possible in that special case where the fields of one2many objects are also function fields which require the context
