How to display man2many fields in list view in odoo 8?

Question

I tried two ways to display many2many field in list view but none of them worked:

1) <field name="test_ids"/> --> It shows just the number of records.(i.e. (3 records))

2) <field name="test_ids" widget="many2many_tags"/> --> It shows the ids of records. (i.e. 2,3,4)

How to achive this?

Answer 1

Normally,

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

must work.

The reason the m2m columns displaying the ids is either your co-model does not contain either name field or _rec_name declaration in the model.
