I've changed the code to: <record id="view_order_line_form_inherit" model="ir.ui.view"> <field name="name">sale.order.line.form.inherit</field> <field name="model">sale.order.line</field> <field name="inherit_id" ref="sale.view_order_line_form2"/> <field name="arch" type="xml"> <xpath expr="/form/sheet/group/group/field[@name='price_unit']" position="before"> <field name="vi_adr"/> </xpath> </field> </record>

In the second point you said that I've to inherit and and the new field, class product_product(osv.osv): _inherit = "product.product" _name = "product.product" _columns = { 'vi_adr': fields.boolean('ADR', help="Check this box if the product needs ADR (Accord europeen relatif au transport international des marchandises Dangereuses par Route)"), } product_product() Is this that you mean or is to add the new field in the sale.order.line?

And the error that I've with the new code is: Can't find field 'vi_adr' in the following view parts composing the view of object model 'sale.order.line': * sale.order.line.form.inherit Either you wrongly customized this view, or some modules bringing those views are not compatible with your current data model openerp.addons.base.ir.ir_ui_view: Can't render view mutante.view_order_line_form_inherit for model: sale.order.line

you must upload your code, then stop and start your server to get openERP to recognize the new fields you added in your python file.

I'm stoping and starting the server by doing this : ./openerp-server -c install/openerp-server.conf --update=mynewmodule, but the error that I've mentioned is always there..

that is wrong, you must FIRST stop the server. ./openerp-server stop SECOND run the command to confirm the server has stopped - ps aux | grep openerp THIRD kill any other running processes FINALLY start the server again ./openerp-server start capitals are for readability because you cannot put new lines in the comments.

I've this error doing like you told me to: ./openerp-server start No handlers could be found for logger "openerp.addons.google_docs.google_docs" Traceback (most recent call last): File "./openerp-server", line 5, in <module> openerp.cli.main() File "/opt/openerp-7.0/openerp/cli/__init__.py", line 51, in main __import__(m) File "/opt/openerp-7.0/openerp/modules/module.py", line 133, in load_module mod = imp.load_module('openerp.addons.' + module_part, f, path, descr)

I've put this working but the error is still here: " Can't find field 'vi_adr' ..."

you must add the attribute to class sale_order_line(osv.osv): if you want to record that information in an order line. If you have a product that is or is not ADR it would be much easier for you to just create 2 different products. I do not know what ADR is, so i cannot adivse you.

So if I had a field to products and if I want that field to appear in the sale_order_line I have to add this field to the class sale_order_line(osv.osv)? ADR - "Accord europeen relatif au transport international des marchandises Dangereuses par Route" Thanks

Yes, but it would probably be easier for you to create a product ADR, and add that to orders that require ADR. Or create 2 product entries - one with ADR and one without, for each of your products. That would remove the need for you to do any custom coding.

Hi, please share all module, tnks
