Hello,

I want to make many2one field readonly=false which is located in one2many field and this field follow the attribute readonly=true from the py file.

Here are defined invoice_line field in base module.

invoice_line = fields.One2many('account.invoice.line', 'invoice_id', string='Invoice Lines', readonly=True, states={'draft': [('readonly', False)]}, copy=True)

What i wan't is in this invoice_line field there is one m2o field is name which is description simply i want to make that field readonly=false whichever state follow the invoice. Below i just try the fields_view_get but didn't get any successful result.

 @api.model

    def fields_view_get(self, view_id=None, view_type='tree', toolbar=False, submenu=False):

#         context = if self.env.context is None:context = {}

        res = super(AccountInvoice, self).fields_view_get(view_id=view_id, view_type=view_type, toolbar=toolbar, submenu=False)

        active_id = self.env['account.invoice'].browse(self.env.context.get('active_id'))

        print "-----------------",active_id.state

        if view_type == 'form':

            fields = res.get('fields', {})

            method_nodes = etree.XML(res['fields']['invoice_line']['views']['tree']['arch'])

            for node in method_nodes.xpath("//field"):

                modifiers = json.loads(node.get("modifiers", '{}'))

                modifiers.update({'readonly':True})

                node.set("modifiers", json.dumps(modifiers))

            for node in method_nodes.xpath("//field[@name='name']"):

                modifiers = json.loads(node.get("modifiers", '{}'))

                modifiers.update({'readonly': False})

                node.set("modifiers", json.dumps(modifiers))

            res['fields']['invoice_line']['views']['tree']['arch'] = etree.tostring(method_nodes)

        return res

 Please give some suggestion.

Thanks in advance.
