How to hide some fields in Form View if no record found in many2many relationship?

Basic idea: Hide few fields in client form view for OpenERP users which are not defined as VIP users in my custom many2many table (user_id, partner_id)

What I've already done:

In res.partner form view:

<field name="vip_ids" widget="many2many_tags" placeholder="VIP users..."/>

My custom module which adds many2many relationship for res.partner module:

from openerp.osv import orm, fields
from osv import fields, osv
class res_partner_users_vip_rel2(osv.osv):
    _inherit = 'res.partner'
    _description = "VIP status for partner (users)"
    _columns = {
        'vip_ids': fields.many2many(
            'res.users',
            'res_partner_users_vip_rel2',
            'partner_id',
            'users_id',
            'VIP status'),
    }
res_partner_users_vip_rel2()

In Form View I can successfully save multiple users in newly created field, but I am stuck at hiding other fields for users who are not defined in my many2many relationship.

As I understand, I need to use attrs attribute but I don't understand how to use it with many2many relationship.

This doesn't work:

<field name="mobile" attrs="{'invisible': [('uid','in', vip_ids)]}"/>
<field name="fax" attrs="{'invisible': [('uid','in', vip_ids)]}"/>
<field name="email" widget="email" attrs="{'invisible': [('uid','in', vip_ids)]}"/>

Any advice would be greatly appreciated :)

I have try this and working :

       <record id="view_0001" model="ir.ui.view">  
            <field name="name">XXXXXXX</field>
            <field name="model">res.partner</field>
            <field name="arch" type="xml">
                <form string="XXXXXXXXXX" version="7.0">
                    <group col="4" colspan="2">
                        <field name="ids_count"/> 
                        <field name="mobile" attrs="{'invisible': [('ids_count','=', 0)]}"/>
                        <field name="fax" attrs="{'invisible': [('ids_count','=', 0)]}"/>
                        <field name="email" widget="email" attrs="{'invisible': [('ids_count','=',0)]}"/> 
                    </group>
                    <field name="vip_ids"></field>

                </form> 
            </field>
       </record>

with modified model definiton

from openerp.osv import fields, osv
class res_partner_users_vip_rel2(osv.osv):
    _inherit = 'res.partner'
    _description = "VIP status for partner (users)"
    def getcount(self, cr, uid,ids,name,arg,context):
        res={}
        sql="""
            SELECT partner_id id, count(*) cnt FROM res_partner_users_vip_rel2 
            WHERE partner_id = """+str(ids[0])+""" GROUP BY partner_id """
        cr.execute(sql)
        res.update(dict(cr.fetchall()))
        if res!={}:
            return res 
        return {ids[0]:0}
    _columns = {                
        'ids_count':fields.function(getcount,type="integer",string='Count'),

        'vip_ids': fields.many2many(
            'res.users',
            'res_partner_users_vip_rel2',
            'partner_id',
            'users_id',
            'VIP status'),
         }

Thanks, but doesn't seem to work. Field is shown both when user is added in many2many relation and also when he s not

Hello, 

It could be achieved without function field and only with xml. You can use attrs attribute like

attrs="{'invisible': [('m2m_field', '=', [(6, False, [])])]}"attrs="{'invisible': [('m2m_field', '=', [(6, False, [])])]}" 
            

On webclient m2m field outputs like [(6, False, [list_of_record_ids])], when there is no record list becomes empty and it outputs like [(6, False, [])] . It can be used in xml condition.

Thanks aharoen. Yesteday evening I came up with similar solution:

def _get_active_ids(self, cr, uid, ids, field_name, arg, context=None):
      result = {}
      for clase in self.browse(cr, uid, ids, context=context):
         result[clase.id] = False
         for membre in clase.vip_ids:
            if membre.id == uid:
                result[clase.id] = True
      return result

class res_partner_users_vip_rel2(osv.osv):
    _inherit = 'res.partner'
    _description = "VIP2 status for partner (users)"
    _columns = {
        'vip_ids': fields.many2many(
            'res.users',
            'res_partner_users_vip_rel2',
            'partner_id',
            'users_id',
            'VIP2 status'),
        'is_current_user_vip': fields.function(
            _get_active_ids,
            type='boolean',
            string="Does current user have VIP access?"),
    }

res_partner_users_vip_rel2()
