Function field, show date field as text - OpenERP v7

Question

So far I'm trying to get a date field data, translated into text format in OpenERP v7.

I made a function on stock module, but when I declare this on my xml view, it returns Undefined tag, and I can't group line by date anymore.

This is my code:

    def _date_(self, cr, uid, ids, fields, arg, context):
    x={}
    for record in self.browse(cr, uid, ids):
        if record.create_date :
            a = date.strptime(record.create_date, "%Y-%m-%d")
            b = a.strftime("%Y-%m-%d")
            x[record.id] = text(b(a))
        return x

    _columns = {
        'create_date': fields.date('Creation Date', readonly=True, select=True),
        'date_': fields.function(_date_, type='text', string='date copy', store=True),

And on stock_view.xml

<filter string="Creation" name="groupby_create_date" icon="terp-go-month" domain="[]" context="{'group_by':'date_'}"

It doesn't actually group them, but show 'undefined' tag, and groups all lines without discrimination by month, which is the normal behavior of create_date date type field, so, how can I achieve this?

I'm making some tests, but I don't see any change on it.

Can someone please shed some light on this?

Thanks in advance!

'date_': fields.function(date, type='date', string='date copy', store=True)

x[record.id] = text(b(a))

and not convert date in text type

Hope this help
