I just want to limit the item that can be input in my

module( let's say 20 lines) which has one2many relationship.

I made some dirty hack in js

I added this line:

if(this.o2m.options.add_limit){
                if(this.records.length < this.o2m.options.add_limit){
                    this._super.apply(this, arguments);
                }else{
                    alert('Cannot add an item \nLimit Exceed:'+this.o2m.options.add_limit);
                }
            }else{
                this._super.apply(this, arguments);
            }

and this in my view.xml:

<field name="one2many_field' options="{"add_limit":28}" />

So the user cannot add item next of it.

Hi,

Here is a more simpler method,

Use @api.constrains to limit the adding of item in a one2many field

Here is sample code:

class SaleOrder(models.Model):
    _name = 'sale.order'
    _description = 'Sale Order'

    name = fields.Char(string='Name')
    sale_lines = fields.One2many('sale.order.line', 'order_id', string='Sale Lines')

    @api.constrains('sale_lines')
    def _check_sale_lines(self):
        for record in self:
            if len(record.sale_lines) > 20:
                raise ValidationError('Not more than 20 lines')

When a user attempts to add more than 20 lines to a sale order, the constraint will be triggered and prevent the change from being saved.

Regards

Hello,

you can use limit in one2many field. like this:

'order_line': fields.one2many('sale.order.line', 'order_id', 'Order Lines', limit=10),

It will limit only the display but adding can still continue. What I mean is that adding of item should stop after 20 lines. Or the "add item" should disappear.

Hello you can check on create method like this: def create(self, cr, uid, vals, context=None): if len(vals.get('line_ids')) > 3: raise osv.except_osv(_('Warning!'), _('Record limit is over!'))
