hi,
is it possible to add the session value to an existing session? let say i
have the session purchase_order that store quantity, user can input price
in form field, i want to store it in session then calculate it.
e.g.
*views/**transaction/**purchase_order.html*
{{price = 5}}
{{grand_total = 0 }}
<table class="table table-condensed table-hover">
<tr>
<th>{{=T('Name') }}</th>
<th>{{=T('Quantity') }}</th>
<th>{{=T('Price') }}</th>
<th>{{=T('Amount') }}</th>
<th>{{=T('Action') }}</td>
</tr>
{{for id, qty in order.items():}}
{{p = db.product(id) }}
{{total_price = qty * price}}
{{grand_total += total_price}}
<tr>
<td>{{=SPAN(p.name) }}</td>
<td>
<form>
<input name="{{='quantity_%s' % p.id}}" value="{{=qty}}" class="span1"
onkeyup="ajax('{{=URL('purchase_order_callback', vars = dict(id = p.id,
action = 'adjust_total_price') ) }}',
['{{='quantity_%s' % p.id}}'], ':eval' )" />
</form>
</td>
<td>
<form>
<input name="{{='price_%s' % p.id}}" value="{{=price}}" class="span1"
onkeyup="ajax('{{=URL('purchase_order_callback', vars = dict(id = p.id,
action = 'adjust_total_price') ) }}',
['{{='price_%s' % p.id}}'], ':eval' )" />
</form>
</td>
<td>
Rp. {{=SPAN('%s' % format(total_price, ",d"), _id =
'total_price_%s' % p.id) }}
</td>
<td>
{{=SPAN(A(I(_class='icon-remove-sign'),
callback=URL('purchase_order_callback', vars=dict(id=p.id, action='remove')
),
delete='tr', _title='Remove from Order') ) }}
</td>
</tr>
{{pass}}
<tr>
<td colspan=3></td>
<td>{{=B(T('Grand Total') ) }}</td>
<td>Rp. {{=SPAN('%s' % format(grand_total, ",d"), _id = 'grand_total')
}}</td>
<td></td>
</tr>
</table>
{{=response.toolbar() }}
*controllers/transaction.py*
def purchase_order_callback():
id = int(request.vars.id)
if request.vars.action == 'adjust_total_price':
quantity = int(request.vars['quantity_%s' % id])
price = int(request.vars['price_%s' % id])
session.purchase_order[id] = quantity
session.purchase_order[id] = price
total_price = quantity * price
grand_total = 0
for calculation_id, calculation_quantity, calculation_price in
session_purchase_order.items():
product = db.product(calculation_id)
calculation_total_price = calculation_quantity * calculation_price
grand_total += calculation_total_price
return
"jQuery('#total_price_%s').html(%s);jQuery('#grand_total').html(%s);" %
(str(id), str(total_price), str(grand_total) )
*response.toolbar : session*
purchase_order:1:2
i've analyze with response.toolbar and got only 1 session store which is
the quantity, i expect to have 2 (quantity and the price base on user input
form field). how can achieve it?
thanks and best regards,
stifan
