If you mean the number of projects related to a customer

class res_partner(osv.Model):

_name = 'res.partner'

_inherit = 'res.partner'

def _get_number_of_projects(self, cr, uid, ids, name, args, context=None):

res = {}

for partner_id in ids:

proj_ids = self.pool.get('project.project').search(cr, uid, [('partner_id', 'in', ids)], context=context)

res[partner_id] = len(proj_ids)

return res

 

_columns = {

'num_of_projects': fields.function(_get_number_of_projects, type='integer', string='Number Of Projects' , store=True),

}

Then in the view :

<record id="inherit_partner_veiw" model="ir.ui.view">

<field name="name">Inherit Partner View</field>

<field name="model">res.partner</field>

<field name="inherit_id" ref="base.view_partner_form"/>

<field name="arch" type="xml">

<xpath expr="//field[@name='website'] " position="after">

<field name="num_of_projects"/>

</xpath>

</field>

</record>

I Hope this helps you :)
