on 10/12/14, 9:04 PM 1,998 views

I made this code to compute the total quantity of the product but the answer is displaying in the view. how can i fix this?? any help please.. Stock.picking.out class...

Here's my code:

 def _get_total_quantity(self, cr, uid, ids, field_name, args, context=None):
        res ={}
        product_qty = {}
        total_quantity= {}
        qty = 0.00
        move_pool = self.pool.get('stock.move')

        for stock_move_picking in self.browse(cr,uid,ids,context=context):
            total_qty = move_pool.search(cr,uid,[('picking_id','=', stock_move_picking.id)],context = context)
            for picking in move_pool.browse(cr,uid,total_qty, context=context):
           qty = qty + picking.product_qty
            res[stock_move_picking.id] = {'total_quantity':qty}
        return res
    _columns = {
               'total_quantity':fields.function(_get_total_quantity, type='float', method=True,store=True, multi=True, string='Summation of Quantity', ),

I think its due to store= True.

because store=True means it will take value from database.

And In database it will store when you create/Update in existing record.

First try without  store = True

But If you want forcefully store value in database then you should try below.

def _get_stock_move_picking_id( cr, uid, ids, context=None):

        ### logic to return id list of parent object.

def _get_total_quantity(self, cr, uid, ids, field_name, args, context=None):

          #Same logic what ever you done 

         res[stock_move_picking.id] = qty

return res               

'total_quantity':fields.function(total_quantity, method=True,string='tOtal Amount',

                                               'YOUR_LINE_OBJECT': (_get_stock_move_picking_id, ['product_qty'], 20),


thanks Piyush but it didn't work:(

Hello ,

your "total_quantity" field also put in stock.picking and check it.


thanks Nirav Jani finally it works.

Please try this one

res[ids[0]] = qty

return res

got the same error too AttributeError: 'float' object has no attribute 'iteritems'

Hi Alcaline,

I find this works for me. v7/v8/v9

import logging

_logger = logging.getLogger('WHATEVER U WANT')

_logger = logging.getLogger(__name__) ## Or FileName of your py.file

_logger.info("Testing: {0}{1}{2}".format(item1, item2, item3))

Now, Im not sure about all your other code, see doc's and check your

Def function & feilds.function are correct.

And test test test... Let us know how you go, & Good luck. 

thanks Vee

You define a function field with type float. So, change the following line

res[stock_move_picking.id] = {'total_quantity':qty}

to this one.

res[stock_move_picking.id] = qty

hi Ben I tried that one but it gives me an Error like this AttributeError: 'float' object has no attribute 'iteritems'. how to solve this one??

Try to set multi=False, in function field definition. I assume no other field is depend on the function.

Hi, I see you update your post. While debugging, what is the value of qty?

Ben Bernard

the value of qty is the summation of Quantity/RSQ. I used this equation to call the value of qty and view to field 'total_quantity' res[stock_move_picking.id] = {'total_quantity':qty} Did i used the wrong equation or what?

Just wondering. It's hard to read other's code in limited context and awful format (provided by this forum).
