Hi,

I am creating one of the module for Investor inside of Builder's ERP and the problem occured while creating the buttons in my Odoo8. Buttons are created but they are disabled; doesn't shows any functionality.

Here is my code,

investor.py

class investor_record(orm.Model):

_name="invest.record"

def button_monthly_interest(self, cr, uid, ids, context=None):

print("Hello Function Started !")

context = context or {}

res = {}

''''''

print("Function Name- Monthly Interest Button-")

for value in self.browse(cr, uid, ids, context=context):

print("For Loop Starts !")

result1 = relativedelta.relativedelta(datetime.today(),datetime.strptime(value.start_date,"%Y-%m-%d"))

print("Monthly Interest")

value.return_amount=((value.roi or 0.0)*(result1.month or 1)*value.amount)

print(value.return_amount)

print("Months")

print(result1.months)

value.returns = (value.amount or 0.0) * (1 + (value.roi or 0.0)*(result1.months or 1))

value.return_amount=value.returns

print("Amount to be Returned!")

print(value.returns)

print(value.return_amount)

return res

def _amount_returns(self, cr, uid, ids, field, arg, context=None):

print("Function for Amount Returns !")

context = context or {}

res = {}

''''''

def monthdelta(d1, d2):

print("Function for Month delta !")

delta = 0

while True:

mdays = monthrange(d1.year, d1.month)[1]

d1 += timedelta(days=mdays)

if d1 <= d2:

delta += 1

else:

break

return delta

for cal in self.browse(self, uid, ids, context=context):

print("For loop for Calculation !")

result2 = relativedelta.relativedelta(datetime.today(),datetime.strptime(cal.start_date,"%Y-%m-%d"))

print("Monthly Interest (Return Amount)!")

cal.return_amount=((cal.roi or 0.0)*(result2.months or 1)*cal.amount)

print(cal.return_amount)

res[cal.id] = (cal.amount or 0.0) * (1 + (cal.roi or 0.0)*(result2.months or 1))

print("Months")

print(cal.months)

return res

_columns={

store={

'value': (lambda self, cr, uid, ids, c={}: ids, ['amount', 'roi'], 10),

},),

}

@api.one

@api.depends('voucher_id.amount')

def _get_voucher_amount(self):

print("Vouchers for Amount!")

self.amt=self.voucher_id.amount

class res_partner(osv.Model):

_inherit="res.partner"

_columns={

'is_investor':fields.boolean('Is an Investor'),

'investment_ids':fields.one2many('invest.record','investor_id',string="Investment Records"),
