To select multiple items you can use many2many field.

In view you have to specify mamy2many tag widget

Eg:

'field_name' : fields.many2many('object.name', string='Details'),

                                <field name="field_name" widget="many2many_tags" />

Although the question is quite old, but still I am answering it for those who are still searching for the solution:

You can use this module to add checkboxes and a button to perform and action on selected records for x2many fields tree view:

Assuming you have created a lines for an object, now those lines are defined in the List/Tree View.

Suppose if you created a field for Product say (many2one), then yes it will show you list of products from which you can select only one at a time.

So instead change the datatype of the product to Many2Many.


Example:

Object A (parent)

lines = fields.One2Many(ObjectB)


Object B (child)

product_ids = fields.Many2Many(product.product)


This way it will let add multiple products into your lines (one2many lines). Hope this helps you

Hi

One2Many field is the virtual field which is used relative to Many2One relationship.

For Example:

Object X:

f1:ManytoOne in OBject Y

Object Y:

f2:ManytoOne in OBject X.f1

It is better to create the Many2Many relationship for storing the multiple values.

Thanks for answer Rajiv, but in many2one relationship also we will select only one item, but i want to select multiple items using one2many field.

Rajiv

I have no idea of selecting multiple items with one2many as its virtual field for the many2one field. Let us expect the answers for this.
