how can I select many items with field many2one?

Asked by Cuong

Hi,

With field many2one, how can I select many items? For ex, my table has product_id, many2one to product.product.
In my form, I want to add many products at once. Currently I can only select each item when I want to add products to my form view.

Thanks,

Hi Lorenzo,

I want each line in relation table to have some fields. For example, I'm doing sale quote. Quote has some fields and a quote line (one2many). Each quote line will have product_id, price. Using many2many is not appropriate.

It means that the relation table will have this schema,
===
quote_id: many2one quote
product_id: many2one product
price1: float
price2: float
===
If using many2many, I cant specify price info for each product.

Thanks,

Hi,

I add widget="many2many" in field o2m and it's changed. But when I click on button 'Add' then error occurs.

Can I customize behavior of this button or widget?

Thanks,

@Cuong: I think with the source code available, you can do whatever changes you think fit, and welcome to contribute your work back to the community. I guess you need to look at the source code for server, around the widget module(s).

Can you help with this problem?
