Hello,

After solving some issue on the Ubuntu side, I have now a "/var/log/openerp-server.log" file working again.

Launching OpenERP server with additional options "--debug --log-level=debug_rpc_answer" now provide me useful informations !!!

When performing "product.template" edition thru the web interface, I captured the following syntax :

'dimension_type_ids': [[6, False, [1, 2]]]

I fully know/understand what is the last part of the "value" => "[1, 2]". This is the list of "foreign IDs" from model "product.variant.dimension.option" I just assigned to my template from the Web interface. But I don't know at all what the begin "6, False" refer to... :(

Does anyone have a clue about this syntax ? I'm not familiar with python at all so maybe this is some particular python syntax ? Or an OpenERP "usual format" ?

Any advice will be nice, I keep searching on my side ;o)

Just FYI, when performing a "read" on the same object I only get :

'dimension_type_ids': [1, 2]

Have a nice day everybody.

UPTADE based on S@@D awesome answer

As only one answer is allowed, I'll update my own response here based on S@@D answer.

For an people looking to use perl as XML RPC interface to OpenERP, here is a sample of template.product object data (ie: a perl hash ref):

$object_data = {
    'name' => 'this is my template',
    'uom_id' => '1',
    'uom_po_id' => '1',
    'procure_method' => 'make_to_order',
    'variant_model_name' => '[_o.option_id.code_]',
    'do_not_update_variant' => '1',
    'sale_ok' => '1',
    'dimension_type_ids' => '[[6, 0, [1, 2]]',
    'variant_model_name_separator' => '\'\'',
    'supply_method' => 'produce',
    'type' => 'product',
    'categ_id' => '24',
    'is_multi_variants' => '1'
};

Where :

'dimension_type_ids' => '[[6, 0, [1, 2]]',

Is an update of a "many2many" field.

Have a look to S@@D link about tuple syntax (sorry but I have not enough karma to add link in my own answer). At the bottom of the developer book documentation page, you will have the "write" explained with all kindly syntax for many2many, one2many, many2one (the simpler one ;) ).

Note: I was only aware of CRUD (create/read/update(ie write)/delete(ie unlink) capability of OpenERP XML RPC... I'll now have a look to others listed in the doc page ;)

Thank you again S@@D Have a nice day

Thank you Nicolas C, i was trying to add some records to a Many2many field in Python.

model_obj.write({'field': [[6, 0, ids]]})
