Hi guys

I dont know what's going on here I tried to set as readonly two buttons when for example I click on it but this dont work.

I have 5 boolean fields to help and I store the True or False option on a database

I have a funtion to update the fields.

class account_invoice(osv.osv):
    _inherit = 'account.invoice'
    
    
    _columns = {
        'impressoori' : fields.boolean('Original ja foi impresso'),
        'impressodupl': fields.boolean('Duplicado Impresso'),
        'impressotri' : fields.boolean('Triplicado ja foi impresso'),
        'impressoall' : fields.boolean('Todas as vias ja foram impressas'),
        'impressoseg' : fields.boolean('Segunda via ja impressa')
    }
    
    _defaults = {
        'impressodupl': False,
        'impressoori': False,
        'impressotri': False,
        'impressoall': False,
        'impressoseg': False,
    }

def update_field_all(self, cr, uid, ids,context):
        for invoice in self.browse(cr, uid, ids):
             cr.execute("UPDATE account_invoice SET impressoall = True WHERE id = %d" %(invoice.id) )
             cr.execute("UPDATE account_invoice SET impressodupl = True WHERE id = %d" %(invoice.id) )
             cr.execute("UPDATE account_invoice SET impressotri = True WHERE id = %d" %(invoice.id) )
             cr.execute("UPDATE account_invoice SET impressoori = True WHERE id = %d" %(invoice.id) )
             
             #raise osv.except_osv(_('This is the error title'), _('This is the error message'))
        return True

My Xml file :

record model="ir.ui.view" id="account_invoice_rule_saft_inherit">
            <field name="name">account.invoice.rule.saft.inherit</field>
            <field name="model">account.invoice</field>
            <field name="inherit_id" ref="account.invoice_form"/>
            <field name="arch" type="xml">
        <notebook colspan="4" position="after">
            <!--<button name="%(account.account_invoices)d" position="replace">-->
