I am trying to add "approve" state to the invoices. I did these changes.
I have inherited "account.invoice" module and view also.
previously invoice has "draft" "open" states i have added "validate" in between draft and open.Just i am updating the state when the user click on "act_validate" signal. It's working fine but i unable to edit the form when it is in "validate" state. Please help me using below code snippet.

_inherit = "account.invoice"
def _paid_amount_in_company_currency(self, cr, uid, ids, name, args, context=None):
if context is None:
context = {}
res = {}
ctx = context.copy()
for v in self.browse(cr, uid, ids, context=context):
voucher = self.browse(cr, uid, v.id, context=ctx)
res[voucher.id] = self.pool.get('res.currency').compute(cr, uid, voucher.currency_id.id, voucher.company_id.currency_id.id, voucher.amount_total, context=ctx)
return res
def approve(self, cr, uid, ids):
self.write(cr, uid, ids, {'state': 'validate'})
return True
_columns = {
'state': fields.selection([
